Description
Technical field
The utility model relates to valve field, relates in particular to a kind of waterpower electro motion control valve.
Background technique
At present, hydro electric brake control valve is the ideal product of tall building feedwater of new generation, draining and waterworks for firefighting.But hydro electric brake control valve of the prior art is prone to the jiggly situation of operation, wayward water velocity in running.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of waterpower electro motion control valve.
The utility model is to be achieved through the following technical solutions:
A kind of waterpower electro motion control valve, comprise main valve, one way stop peturn valve, solenoid valve, hydraulic fluid port on the valve gap of described main valve connects a hydraulic fluid port of one way stop peturn valve by conduit, another hydraulic fluid port of one way stop peturn valve connects the main hydraulic fluid port on valve body of main valve, one hydraulic fluid port of described solenoid valve is also connected on the hydraulic fluid port on the valve gap of main valve by conduit, and another hydraulic fluid port of solenoid valve connects the main hydraulic fluid port on valve body of main valve.
As optimal technical scheme of the present utility model, described main valve is diaphragm type main valve.
As optimal technical scheme of the present utility model, described diaphragm type main valve comprises valve body, described valve body comprises entrance point and outlet end, on described valve body, valve gap is installed, in valve pocket in valve body, valve rod is installed, on described valve rod, spring is installed, one end contact valve gap of described spring, the other end is connected on diaphragm on platen, on diaphragm, between platen and diaphragm pressing disc, diaphragm is installed, in one end of described valve rod, be connected with platen on seal ring, on seal ring, between platen and seal ring pressing disc, seal ring is installed, the upper end of described valve gap is provided with suspension ring by tightening hexagon nut.
Its working principle is: when the water pump in system is opened, main valve entrance point has the WATER AS FLOW MEDIUM of pressure to act on valve rod, simultaneously entrance point has and has conduit, the one way stop peturn valve that the WATER AS FLOW MEDIUM of pressure is connected with main valve control chamber by main valve entrance point, enters main valve control chamber.At this moment, the pressure in main valve control chamber equates with the pressure of main valve entrance point.When supravasal normally closed solenoid valve no electric circuit that main valve outlet end is connected with main valve control chamber, the WATER AS FLOW MEDIUM with pressure in its main valve control room can not flow to main valve outlet end, and diaphragm is produced to an active force.Because the lifting surface area of diaphragm is larger than the lifting surface area of valve rod, valve rod is still in closed condition.Be connected with main valve control chamber when main valve outlet end 1 energising of supravasal normally closed solenoid valve time, the WATER AS FLOW MEDIUM with pressure in its main valve control room can be sent out and flow to main valve outlet end, the WATER AS FLOW MEDIUM that main valve entrance point has certain pressure produces an active force to valve rod, when the active force of its generation overcomes total power of the power of the spring in main valve control chamber and the power of valve rod deadweight, valve rod rises, and main valve is opened.
When water pump cuts out, decrescence and level off to zero, the medium in pipeline starts adverse current to the pressure of main valve entrance point.Its counter-flow media has certain pressure, there is conduit, the normally closed solenoid valve (solenoid valve on it must be charged) that the counter-flow media water of certain pressure is connected with main valve control chamber by main valve outlet end and enter main valve control chamber, valve rod diaphragm is produced to the active force that valve rod is moved down.Pressure in main valve control chamber equates with the pressure of main valve outlet end.On the conduit being connected with main valve control chamber due to main valve entrance point, an one way stop peturn valve is housed, the counter-flow media water in main valve control chamber with certain pressure can not flow to main valve entrance point.So active force, the active force of spring that valve rod produces in the counter-flow media that has certain pressure are, close under the effect of three kinds of active forces of power of valve rod deadweight.
Compared with prior art, the beneficial effects of the utility model are: this valve can be opened or close to the utility model at a distance, desirablely substitute the Large Electric such as opening and closing gate valve or butterfly valve to operate machine, and the feature such as easy to maintenance, reliable; This valve can be used in feedwater, the drainage system pipes such as tall building, industry, agricultural, life, protection pipeline and equipment thereof; Simultaneously can the operation of assurance system steadily, be convenient to control water velocity.
