The novel multifunctional hydraulic control valve has the functions of three valve pieces such as gate valve, check valve and water hammer canceller, can effectively improve the safety and reliability of the water supply system, and saves occupied space and investment. The valve has a plurality of functions, can achieve various use requirements when being installed on pipelines with different needs by only making a simple switch, and has wide application scope.
Description
Technical field
The utility model belongs to city planting ductwork water system control gear, particularly a kind of multifunctional water force control valve.
Background technique
On the exit of pump pipeline of city planting ductwork water system and other water supply system, adopt the method that mortor operated valve, check valve and water-hammer arrester are installed to prevent that medium from flowing backwards, and prevents the generation of water hammer and water hammer at present.Exist to install complicated, cost is high, complex operation, can't realize defective such as control automatically.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned shortcoming, a kind of multifunctional water force control valve to be provided.
For achieving the above object, the technological scheme of the utility model multifunctional water force control valve is that it comprises valve body, valve rod, valve seat, big valve flap, little flap, middle valve gap, diaphragm, diaphragm pressing plate and bonnet; Wherein go up, middle valve gap, valve rod, diaphragm and little flap connect as a wholely, is with spring between valve rod upper valve base and the little flap; Diaphragm constitutes two chambers driving mechanism with being divided into two different pressure chambers in the valve body; Big valve flap can slide up and down on valve rod.
The utility model multifunctional water force control valve is worked under the conduit control system cooperates during use.The conduit control system is made up of ball valve, little safety check, filter and pipeline etc.A conduit control system part is communicated with main valve import and control room cavity of resorption, and another part is communicated with main valve outlet and control room epicoele.
When being used in exit of pump, during starting mode of pump, the main valve inlet pressure raises, and press water enters the control room cavity of resorption by ball valve, filter, and it is up to promote to touch the sheet pressing plate, drives little flap and opens, and big valve flap is opened simultaneously with little flap under the promotion of current, finishes out valve.Simultaneously, the water of control room epicoele flows to the main valve outlet through filter for molten, ball valve.The adjusting control valve aperture makes the opening speed of little flap be in slow state, can guarantee the starting time of the opening time of main valve greater than pump motor, realizes that underloading opens pump, avoids producing the turn on pump water hammer because of opening the valve excessive velocities.When water pump cut out, the main valve inlet pressure was lower than outlet pressure, and big valve flap falls rapidly and closes under the effect of gravity, blocks about 90% current.Simultaneously, the press water of main valve outlet enters the control room epicoele, and it is descending to promote the diaphragm pressing plate, and little flap is closed, and finally realizes closing fully of main valve.By regulating the aperture of main valve outlet end ball valve, the downstream rate of may command diaphragm pressing plate realizes the Slow Close of little flap, eliminates pump-stopping water hammer effectively.
When being used in city planting ductwork and providing the outlet of water water pump two water pipelines for oneself,, regulate intelligent controller, realize pump motor and time, pressure setting and three-way solenoid valve interlocked control according to customer requirements manual tune control valve.Realize the full automatic multipurpose use of hydraulic control valve.
The utility model has the valve of gate valve, check valve and three kinds of valve member functions of water-hammer arrester simultaneously, can improve the safety reliability of water system effectively, saves to take up an area of the space, reduces investment outlay.This valve has multiple function, is installed on the pipeline of different demands and only need does simple switching, can realize the multiple use requirement, applied range.This valve cooperates with intelligent control system, can realize that pressure sensing, time are controlled and Electrified Transmission is controlled then complex operations, realizes fully-automatic intelligent control, saves a large amount of manpower and materials.This valve adopts airflow design, and the pressure loss is little, and flow is big, the operational efficiency height.

Embodiment
Embodiment, as shown in Figure 1, the multifunctional water force control valve comprises valve body 1, valve rod 2, valve seat 3, big valve flap 4, little flap 5, middle valve gap 7, diaphragm 8, diaphragm pressing plate 9 and bonnet 12; Wherein bonnet 12, middle valve gap 7, valve rod 2, diaphragm 8 and 5 connections of little flap are as a whole, and 5 of valve rod 2 upper valve bases 3 and little flap are with spring 17; Diaphragm 8 constitutes two chambers driving mechanism with being divided into two different pressure chambers in the valve body 1; Big valve flap 4 can slide up and down on valve rod 2.
The conduit control system is made up of ball valve 14, little safety check, filter 16 and pipeline etc.A conduit control system part is communicated with main valve import and control room cavity of resorption, and another part is communicated with main valve outlet and control room epicoele.
When being used in exit of pump, adjustment control valve (6), (15) are in opening state, closed control valve (11) (14).When starting mode of pump, the main valve inlet pressure raises, and press water enters the control room cavity of resorption by ball valve (15), filter (16), it is up that sheet pressing plate (piston) is touched in promotion, drive little flap and open, big valve flap is opened simultaneously with little flap under the promotion of current, finishes out valve.Simultaneously, the water of control room epicoele flows to the main valve outlet through filter for molten (10), ball valve (6).Adjusting control valve (15) aperture makes the opening speed of little flap be in slow state, can guarantee the starting time of the opening time of main valve greater than pump motor, realizes that underloading opens pump, avoids producing the turn on pump water hammer because of opening the valve excessive velocities.When water pump cut out, the main valve inlet pressure was lower than outlet pressure, and big valve flap falls rapidly and closes under the effect of gravity, blocks about 90% current.Simultaneously, the press water of main valve outlet enters the control room epicoele, and it is descending to promote diaphragm pressing plate (piston), and little flap is closed, and finally realizes closing fully of main valve.By regulating the aperture of main valve outlet end ball valve (6), the downstream rate of may command diaphragm pressing plate (piston) realizes the Slow Close of little flap, eliminates pump-stopping water hammer effectively.
