Configuration it is complex.
The content of the invention
The present invention in view of the shortcomings of the prior art, propose it is a kind of just can stably loine pressure, flow by simple structure
Voltage stabilization and current stabilization valve.
The present invention is achieved through the following technical solutions technical goal.
Voltage stabilization and current stabilization valve, it is theed improvement is that：Including housing, diaphragm, valve, valve seat, lower spring, upper spring；It is described
In housing cavity, diaphragm outer wall coordinates diaphragm horizontal with housing cavity gap, and housing cavity is divided into upper and lower chamber；The valve
Seat is arranged in housing cavity cavity of resorption, and valve seat is vertically arranged provided with central axis, the valve seat orifice of up/down perforation, and valve seat orifice bottom is provided with
Taper hole directed downwardly is held greatly；The valve includes valve body, the push rod above valve body, and the valve valve body is and valve seat hole bottom
The corresponding cone of taper hole；The valve stem runs through valve seat hole；The upper spring is arranged on diaphragm upper surface and housing
Between the upper surface of inner chamber；The lower spring is arranged on below valve, and valve is pushed up upwards, is made under valve stem upper surface and diaphragm
End face keeps contact；The side wall in the valve seat hole is provided with the radial direction through hole communicated with valve seat hole, valve seat radial direction through hole
Connected by collateral road with housing cavity epicoele；The lower housing portion is provided with the entrance point connected with housing cavity cavity of resorption, housing
Top is provided with the port of export connected with housing cavity epicoele；Being provided with the collateral road makes air-flow can only be from valve seat radial direction through hole stream
To the check valve of housing cavity epicoele.
In said structure, flow control valve, flow agent are provided with the collateral road.
The present invention compared with prior art, has the positive effect that：
1st, the present invention is provided with valve, valve seat, the gap between valve valve body and valve seat hole bottom taper hole, controls air inlet pipeline
Flow.Upper spring is provided with above diaphragm, lower spring is provided with below valve, the side wall in valve seat hole is provided with and valve seat hole
The radial direction through hole communicated, valve seat radial direction through hole are connected by collateral road with housing cavity epicoele；Voltage stabilization and current stabilization valve is provided with and housing
The voltage stabilization and current stabilization valve entrance point of inner chamber cavity of resorption connection, voltage stabilization and current stabilization valve entrance point connect with the port of export of the first stop valve；Voltage stabilizing
Flow stabilizing valve is provided with the voltage stabilization and current stabilization valve outlet end connected with housing cavity epicoele, and voltage stabilization and current stabilization valve outlet end exports with air inlet pipeline
End connection.So, in use, when air inlet pipeline pressure or flowed fluctuation, pass through diaphragm and promote valve movement, control valve valve body
With the gap between the taper hole of valve seat hole bottom, so as to reach the purpose of stable air inlet pipeline pressure or flow, the present invention is logical
Crossing simple structure just can stable loine pressure, flow.
2nd, check valve is provided with collateral road, air-flow is flowed to housing cavity epicoele from valve seat radial direction through hole, plays
Anti- backflow effect.
3rd, flow control valve, flow agent are provided with collateral road, on the one hand passes through Flow-rate adjustment valve regulation air inlet pipeline flow；
On the other hand, measurable air inlet pipeline flow.
