Abstract
The utility model discloses a hydraulic diaphragm-type control valve which comprises a valve body and valve flaps, wherein a water inlet and a water outlet are formed at the two ends of the valve body, an isolator is arranged between the water inlet and the water outlet, a water plugging hole is formed on the isolator and engaged with the valve flaps, an upper cover is arranged at the upper end of the valve body, a sliding valve rod is arranged on the inner wall of the upper cover, the valve flaps are fixed and engaged to the lower end of the sliding valve rod, a diaphragm press plate is arranged at the upper end of the valve flaps, a diaphragm is clamped between the diaphragm press plate and the valve flaps, and a spring is arranged and connected between the upper end of the diaphragm press plate and the inner wall of the upper cover. The hydraulic diaphragm-type control valve requires accurate and errorless steam blockage and water drainage, is high in sensitivity, can increase the steam utilization rate, prevents steam leakage, works reliably, has a high backpressure rate and a long service life, is convenient in maintenance, and is the best choice.
Description
Technical field
The utility model relates to valve field, belongs to more specifically a kind of waterpower diaphragm type control valve.
Background technique
Hydraulic control valve is take pipe medium pressure as power, and the valve that opens and closes, regulates has increased diaphragm between flap and diaphragm pressing plate, added spring on the diaphragm pressing plate with on valve upper cover, when impact of water hammer occured, flap was by the spring pull-up, and water just is difficult for entering valve body top, select hydraulic control valve to require block steam and drain water like clockwork, highly sensitive, can improve steam utilization, not leaked steam, reliable working performance, Rate of back pressure is high, long service life, easy to maintenance be first-selected condition.Present valve mechanism is simple, can cause to block water and gas leak phenomenon, and the discharging energy is inadequate, can cause water of condensation in time not discharge, and reduces the thermal efficiency of heating plant.
The model utility content
The purpose of this utility model is to provide a kind of waterpower diaphragm type control valve, and hydraulic control valve requires block steam and drain water like clockwork, and is highly sensitive, can improve steam utilization, leaked steam not, reliable working performance, Rate of back pressure is high, long service life, easy to maintenance be first-selected condition.
The technical solution of the utility model is as follows:
A kind of waterpower diaphragm type control valve, include valve body, flap, the two ends of described valve body are respectively equipped with entery and delivery port, have slider between entery and delivery port, have the water blockoff hole of matching with flap on slider, the upper end of valve body is provided with upper cover, the inwall of upper cover is provided with sliding stem, described sliding stem lower end secure fit has flap, the upper end of flap is provided with the diaphragm pressing plate, be gripped with diaphragm between diaphragm pressing plate and flap, be provided with spring between the upper end of diaphragm pressing plate and the inwall of upper cover and be connected.
Be combined with guide sleeve between described sliding stem and upper cover.
The utility model force control valve requires block steam and drain water like clockwork, and is highly sensitive, can improve steam utilization, leaked steam not, reliable working performance, Rate of back pressure is high, long service life, easy to maintenance be first-selected condition.
