At present, the water sources of hotels and inns are mostly municipal tap water or well water, all of which have the problem of relatively high water hardness. In practical applications, it is easy to cause equipment scaling, unstable heat exchange efficiency, hard and gray clothes in the laundry room, and serious waste of detergent, etc. To effectively solve the above problems and enhance the commercial image of hotels and guesthouses,Softened water equipmentIt has been widely applied

　　According to the water supply department, the water we use and drink at present does indeed come in two types: soft and hard. For a long time, due to the limitations of technology and equipment, the production and supply of tap water in our country have contained relatively high levels of chemical elements such as fluorine, iodine, copper, zinc, calcium and magnesium, and thus are classified as hard water. Scientific experiments have proved that the higher the hardness of drinking water, the higher the incidence of hypertension, heart disease, cerebrovascular and kidney stones in the population. At the same time, it also brings some troubles to People's Daily lives, such as the constant formation of scale in the sink and bathtub. The water pipes and shower heads are rusted and hardened, and the white shirts turn yellow after washing. Good tea fails to taste good and becomes insipid and bitter, etc.

　　Softening water equipment removes heavy metals from water, turning hard water into soft water. Drinking soft water treated by softening water equipment tastes good and has no peculiar smell. Using soft water can save money. Because soft water does not form scale and does not cause rust, it will reduce the amount of soap and laundry detergent used in household washing, and decrease the occurrence of chronic diseases such as heart, brain and kidney problems. Meanwhile, soft water can effectively inhibit. When a skin injury or similar accident occurs, first wash the affected area with soft water, then soak absorbent cotton, gauze, towel, etc. in soft water and gently rub the affected area. This can quickly heal the wound and make the caused swelling disappear immediately. This is because soft water has the function of regenerating cell tissues.

　　Beijing Yuanlai Company is introducing the United StatesFleck Based on the new type of program controller, combined with the characteristics of water quality conditions and the actual operation experience of the equipment, an energy-saving fully automatic water softening equipment suitable for the usage conditions has been developed. The control device of the fully automatic water softener is imported from the original factory in the United States. The tank body is made of various materials: fiberglass reinforced plastic, carbon steel lined with plastic, and stainless steel, and can be flexibly designed according to the needs of users. The resin is in good use.001×7Strong acid type sodium ion exchange resin The salt dissolving tank adoptsPEMaterial.

　　Working principle: The hardness of water is mainly determined by the cations in it: calciumCa2+"Magnesium"(Mg2+)Composed of ions. When the raw water containing hardness ions passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are exchanged with the sodium ions in the resin. The resin adsorbs the calcium and magnesium ions while the sodium ions enter the water. Thus, the water flowing out of the exchanger is softened water with the hardness ions removed. As the exchange process continues, in the resinNa+Once all are taken out, the exchange function is lost and it is used at this pointNaclThe solution regenerates the resin and adsorbs itCa2+,Mg2+After being replaced, the resin re-adsorbed sodium ions and restored its softening exchange capacity.

　　The fully automatic water softening equipment, also known as the fully automatic water softener, is mainly applied in industrial water use such as boiler softening, cooling water replenishment, and chemical batching. The fully automatic water softener mainly consists of a water softener tank and a fully automatic control valve.PEIt is composed of a salt tank, a regeneration system for softening resin and connecting pipelines. Among them, the fully automatic control valve is like the brain of the human body, directing the operation of the entire softening water system, such as backwashing, regeneration, cleaning and water injection. Therefore, for a softening water device, choosing the right control valve is very important, as it is related to the reliability and stability of the entire system's operation. Now, what Yuanlai Jun recommends to you is an American brandfleckFleck, now let's specifically introduce the relevant knowledge of Fleck control valves:

　　It is classified into four series according to its application and structural features:

　　1The series of small civil control valves mainly consists of5600,5600SE,5000,6600,6700It is composed of a type of control valve and is suitable for single-valve and single-tank systems.

　　Structural features: The pistons are arranged longitudinally, and the valve body material is all engineering valve body material plastic. During regeneration, there is a hard water bypass, and an additional valve or solenoid valve is needed to block the hard water.5600The type of regeneration procedures include7The process involves two more cleaning steps than other valves, and the regeneration quality is superior to that of other valves. It is suitable for small civilian water softeners.

　　2The single-piston industrial control valve series mainly consists of2510,2750,2850,3150It is composed of a type of control valve and is suitable for single-valve and single-tank systems. If it is used in a double-tank system, additional valves are required to achieve this.

　　Structural features: The pistons are arranged laterally. In addition to2510All other valve body materials are lead-free brass.

　　Optional bypass piston without hard water, with a large backwash flow rate. If it is configured as a double-tank system, additional valves need to be added to achieve this. It is applicable to boiler water softeners and other industrial water softeners.

　　3The double-piston industrial control valve series mainly consists of2900,3900It is composed of a type of control valve and is suitable for double-tank systems without the need for additional valve control.

　　Structural features: The pistons are arranged laterally, with two pistons. One controls the regeneration program, and the other realizes the switching of water inlet and outlet. The valve body material is all lead-free brass, and a hard-water bypass piston can be optionally equipped. It can be configured into a dual-tank system or a multi-tank system without the need for additional valves. It is applicable to water softeners for boilers and other industrial water softeners.

　　4The dual-tank one-in-use and one-standby control valve series mainly consists of8500,9000,9500It is composed of a type of control valve, with a single valve simultaneously controlling two resin tanks(One in use and one on standby, alternating and regenerating)It can continuously supply softened water. Due to the use of soft water regeneration, the regeneration effect is good and it is suitable for various water usage scenarios. For systems with large water consumption, multiple units can be operated in parallel.

　　Structural features: One valve controls two tanks, with two pistons. One controls the regeneration program, and the other enables the two tanks to switch between each other. Regeneration is initiated by the flow rate. In addition to8500The valve body is made of lead-free brass. It is suitable for occasions that require continuous supply of softened water and adopts a one-in-use and one-standby form.

　　Control valves can also be classified into those with hard water bypass and those without based on whether hard water enters the system during regeneration. Small civil control valves belong to the category with hard water, single-piston industrial control valves and double-piston industrial control valves belong to the optional category without hard water, and double-tank control valves with one in use and one as backup belong to the category without hard water.

　　Due to its reliable stability, Fleck control valves are widely used in water softening devices and play a crucial role in the water treatment industry.
