Description
Technical field
The utility model relates to a kind of gas liquid type series flow control valve.
Background technique
The various series flow control valves that present stage uses generally are screw types, by the screw rod rotation spool are moved axially.But there is following shortcoming in the screw type series flow control valve: 1, screw type series flow control valve volume is big, and mechanical parts are many, and is easy to wear, just can not normally use during serious wear; 2, screw type series flow control valve complicated operation in use, and since the screw rod rotation when opening slowly speed of response slow; 3, the screw type series flow control valve can only be manual, and automatic controlling level is low.Therefore the screw type series flow control valve has been difficult to satisfy the on-the-spot new demand to aspects such as control valve automations that improves day by day, a kind of long service life of market in urgent need, deadweight are little, compact structure, can control automatically, New Structure Speed Control Valve that speed of response is fast.
The model utility content
The purpose of this utility model provides that a kind of speed of response is fast, automaticity is high, in light weight, apparent size is little, the gas liquid type series flow control valve of long service life.
For achieving the above object, the utility model is taked following design proposal:
A kind of gas liquid type series flow control valve is characterized in that it comprises:
One has the left cylinder of shoulder hole, described shoulder hole left end is a macropore for the aperture right-hand member, described left cylinder outer wall is provided with first suction port of the macropore left end that is communicated with described shoulder hole and is communicated with second suction port of the macropore right-hand member of described shoulder hole, and the ingress of described left cylinder has inwardly protruded out a baffle ring;
One has the right cylinder body of entrance and exit, described right cylinder body middle part is formed with a valve seat, described valve seat has along circumferential equally distributed a plurality of through holes, described valve seat middle part has protruded out ring-type retaining edge left, described valve seat left end is bolted to connection the block of an external diameter less than the ring-type retaining edge internal diameter of described valve seat, and described block right-hand member has annular recess; The left end of described right cylinder body is connected by bolt with the right-hand member of described left cylinder;
Primary seal pad between the inwall of the left side of one annular recess that is located in described block, valve seat and valve seat ring-type retaining edge;
One is positioned at the tubular plunger of the inlet of the shoulder hole of left cylinder and right cylinder body, described plunger middle part outer wall has outwards protruded out a collar flange, described plunger with respect to left cylinder and right cylinder body for slidably being connected, be provided with guide ring and sealing gasket between the aperture inwall of described plunger left end outer wall and described left cylinder shoulder hole, be provided with seal ring between the macropore inwall of the outer wall of the collar flange of described plunger and described left cylinder shoulder hole, be provided with guide ring and sealing gasket between the right-hand member outer wall of described plunger and the described right cylinder body inlet inwall, described plunger right-hand member external diameter is less than the internal diameter of the ring-type retaining edge of described valve seat, and described plunger right-hand member internal diameter is greater than the external diameter of described block.
The collar flange left side of described plunger is fixedly connected with one and convexedly stretches in the outer travel indicator that has scale of described left cylinder.
The utility model has the advantages that:
1, the utility model gas liquid type series flow control valve is owing to adopt above-mentioned design proposal, and the through hole and the right cylinder body of the gap between left cylinder inlet, plunger endoporus, plunger and the primary seal pad, the valve seat of right cylinder body go out the first-class body passage of interruption-forming.During use, first suction port is connected with air pump (or liquid pump) by two-position-five-way solenoid valve with second suction port, when control gaseous (or liquid) enters the collar flange of plunger and the cavity between the right cylinder body by second suction port, control gaseous (or liquid) promotes plunger and moves to the left, open in space between plunger and the sealing gasket, and fluid flows through in the fluid passage smoothly.When control gaseous (or liquid) when first suction port enters cavity between left cylinder and the collar flange, control gaseous (or liquid) promotes plunger and moves to the right and compresses sealing gasket until the plunger front end, fluid is cut off.Therefore the unlatching of the utility model gas liquid type series flow control valve can be adopted pneumatic control (or the control of surging), and speed of response is fast, in light weight, apparent size is little, long service life, and can cooperate two-position-five-way solenoid valve and air-liquid converter to realize automation control.And the open and close of this series flow control valve does not all have pivoting friction torque, and open and close are convenient, no jam phenomenon.
2, the utility model gas liquid type series flow control valve, wherein plunger is directly to be pressed on the sealing gasket when closing series flow control valve, and the pressurize of when work; Left cylinder has adopted the stair ring sealing simultaneously, can reach zero leakage.
3, the utility model gas liquid type series flow control valve, compact structure does not take up space, just like one section adapter, installation, convenient disassembly.
4, the utility model gas liquid type series flow control valve wherein is installed in the working state that the travel indicator that has scale on the plunger can be judged plunger.
5, the utility model gas liquid type series flow control valve has adopted guide ring, and its stable action does not have and impacts, long service life.
