Summary of the first valve of the first valve: Today is very happy to introduce the characteristics of the multi-function water pump control valve, because these features make this valve have more comprehensive performance, let's take a look at what is different.
Hammer Drill, also known as a percussion drill or Impact Drill, is a power Tool used chiefly for drilling in hard materials. It is a type of rotary drill with an impact mechanism that generates a hammering motion. The percussive mechanism provides a rapid succession of short hammer thrusts to pulverize the material to be bored, so as to provide quicker drilling with less effort. If a hammer drill's impact mechanism can be turned off, the tool can be used like a conventional drill to also perform tasks such as screwdriving.
A preliminary summary of the first valve:
Today I am very happy to introduce the characteristics of the multi-function water pump control valve, because these features make this valve have more comprehensive performance, let's take a look at what is different.
Features:
1. The double-chamber diaphragm control structure of the multi-function water pump control valve can realize online maintenance of the valve, greatly reducing maintenance time and cost.
2. Spray polymer coating on the inner and outer surfaces of the valve to improve the surface anti-corrosion performance.
3. The control line has a backwash function. During the process of opening and closing the valve, the water flow in the control line is reversed, and the impurities in the filter can be rinsed clean. This makes the filter not easy to block, and can be adapted to the poor water quality conditions such as raw water and sewage.
4, no water hammer calculation, no on-site professional debugging, fast closing time automatically corresponds to zero flow time. This avoids possible water hammer hazards caused by calculation errors, debugging errors, and control errors.
5. The diaphragm is reinforced with special rubber and nylon mesh. After the Hunan Provincial Rubber and Rubber Products Quality Supervision and Inspection Authorized Station, the number of fatigue bending of the diaphragm fatigue is more than 1.2 million times without cracking (with provincial inspection report).
6. Eliminate the water hammer device and the valve opening and closing action is completely interlocked, and has the functions of quick closing, slow closing, and absorption of water hammer.
7. The main material of the valve is in accordance with the industry standard CJ/T167-2002 "Multi-function water pump control valve". When using cast steel (WCB), its tensile strength, compressive strength and elongation are better than ductile iron.
8, the entire process of automatic operation. When the pump is turned on, the pressure of the water in the pipeline rises to make the valve automatically open slowly, so that the motor can start at no load, reduce the starting surge current, ensure the safe use of electrical equipment and components, and avoid the water hammer of the pump; The valve automatically realizes two-stage closing, which is very suitable for automatic control of modern water plants.
9, no electrical and hydraulic components, no heavy hammer, and can reliably eliminate the impact of the pump water hammer, so fewer points of failure, basically no maintenance, long service life.
10. Multi-function water pump control valve adopts metal seal type between the slow-closing valve plate and the main valve plate. The new patented “Tâ€-shaped nitrile rubber ring seal and metal seal double seal type are used between the main valve plate and the main valve plate seat. , no movement and wear, reliable sealing performance and long service life.
11. The dual-chamber diaphragm control method is used instead of the piston type control method, which has the following advantages:
a. Stop the water shut off smoothly without generating pressure fluctuations;
b. A quick and sensitive action response can be achieved;
c. no movement and wear;
d. no leakage due to impurities;

e. is not sensitive to silt deposition;
f. There are no seals that need to be replaced regularly;
g. No lubrication is required.
12. Adopting the most advanced “Y†wide valve body, streamlined and semi-linear flow channel basic structure, and through improvement and innovation, the resistance loss is reduced by more than 50% compared with similar foreign products. The "Y"-shaped wide valve body structure also has the characteristics of large flow rate, light weight and strong resistance to cavitation damage.
