Abstract
The utility model discloses a high-sealability valve seat for an electromagnetic valve. The high-sealability valve seat comprises a valve seat body, a valve cavity is arranged in the middle of the valve seat body, an inlet pipe and an outlet pipe are arranged at two ends of the valve seat body respectively, an internal thread area for mounting the electromagnetic valve is arranged on the inner wall of a valve cavity opening, an annular boss is arranged at the bottom center of the valve cavity, an annular groove is reserved between the outer wall of the annular boss and the inner wall of the valve cavity and is communicated with the inlet pipe, a columnar through hole is arranged in the annular boss and communicated with the outlet pipe, and a rubber seal ring matched with an electromagnetic valve spool is embedded into the upper end face of the annular boss. The high-sealability valve seat for the electromagnetic valve is simple in structure and convenient to use, and the design that the rubber seal ring is embedded into the upper end face of the annular boss in the valve seat body can enable the valve seat to be better matched with the spool of the electromagnetic valve so that sealing is achieved, wear between the spool and the boss is reduced, the service life of the spool is prolonged, and normal operation of the electromagnetic valve is guaranteed.
Description
Technical field
The utility model relates to a kind of valve seat, is specially a kind of solenoid valve high leak tightness valve seat.
Background technique
Solenoid valve is the industry equipment with Electromagnetic Control, is used in direction, flow, speed and other the parameter of adjusting medium in the industrial control system.Solenoid valve can cooperate different circuit to realize the control of expecting, and precision and the flexibility of control can both guarantee.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system, and the most frequently used is one-way valve, safety valve, position control valve, speed-regulating valve etc.Valve seat is one of parts important in the solenoid valve, be used for controlling component and the controlled pipeline of connected electromagnetic valve, yet existing valve seat cooperates defective tightness with valve core of the electromagnetic valve in use, and the boss that cooperates with spool in the valve seat causes wearing and tearing to spool easily, damage easily the spool of solenoid valve after long-time the use, and then affect the normal operation of solenoid valve.
The model utility content
The purpose of this utility model provides a kind of solenoid valve high leak tightness valve seat, traditional valve seat cooperates defective tightness with valve core of the electromagnetic valve in use in the prior art to solve, and the boss that cooperates with spool in the valve seat causes wearing and tearing to spool easily, damage easily the spool of solenoid valve after long-time the use, and then affect the problem of solenoid valve normal operation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of solenoid valve high leak tightness valve seat, it is characterized in that: include the valve seat body, described valve seat middle part is provided with valve pocket, two ends are respectively equipped with into and out of pipe, the internal threaded regions that described valve pocket opening inwall is provided with to install solenoid valve, described valve pocket bottom centre is provided with annular boss, leave annular groove between described annular boss outer wall and the valve pocket inwall, be provided with the column through hole in the described annular boss, described annular groove is communicated with inlet pipe, described column through hole with go out pipe and be communicated with, described annular boss upper-end surface is embedded with the rubber seal that cooperates in order to valve core of the electromagnetic valve.
Described a kind of solenoid valve high leak tightness valve seat is characterized in that: be raised with respectively mounting ear into and out of pipe one side on the described valve seat, described mounting ear is provided with mounting hole.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, the design of employing annular boss upper-end surface embedding shape rubber seal in valve seat, can better cooperate the spool of solenoid valve to reach the purpose of sealing, and the wearing and tearing between spool and the boss have been reduced, prolong the working life of spool, guaranteed the normal operation of solenoid valve.
