Throttle valve is by changing the throttling section or throttle valve to control the fluid flow length. Throttle valve is an important part of the household, as a result, many consumers attaches great importance to the quality of the throttle valve.
One, the throttle valve with what works
1, change the media channel cross-sectional area
All kinds of block valves can change medium channel cross-sectional area, thus can also play a regulatory role in extent, but they regulation performance is not good. This is because they are the opening and closing of the valve stem and active connection, in joint with clearance, the inconvenience to adjust; Open-close part of the lift is out of proportion with the changes in the channel area, and therefore is not easy to be accurate, continuous adjustment; When the channel area of small and medium velocity is large, will cause serious erosion, sealing surface and cause the vibration of the disc. Therefore usually adopts special structure and shape of the throttle valve opening and closing a regulation.
2, used to regulate water flow
Throttle valve is mainly used for adjusting flow rate and pressure, to consider when choosing the valve flow control, pressure drop and load, etc., in order to avoid premature failure and ensure the safe use. Specially designed for high pressure differential throttling valve requires the valve sealing element. On the whole, through the disc big differential pressure shall not exceed 20% of the upstream pressure or 200 psi both in the smaller values. With specialized packing element of the valve can be used beyond the occasion of the differential pressure.
Throttle valve has good practical value, plays an important role in the bedroom decorates, thus become the product of the bedroom. In daily life, we can use the above method to choose a throttle valve, to ensure that the bedroom neat and beautiful.
