Abstract
The utility model discloses a low-resistance high-seal valve seat for an electromagnetic valve. The low-resistance high-seal 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 respectively arranged at two ends of the valve seat body, an inner threaded area used for mounting the electromagnetic valve is arranged on the inner wall of an opening of the valve cavity, an annular boss is arranged at the center of the bottom 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, a cylindrical through hole is reserved in the annular boss and is communicated with the inlet pipe, the bottom surface of the annular groove is a tilted surface tilting towards the inlet pipe, the cylindrical through hole is communicated with the output pipe, and a rubber sealing ring matched with a valve spool of the electromagnetic valve is embedded on the upper end face of the annular boss. The low-resistance high-seal valve seat is simple in structure and convenient to use, resistance of the valve seat to flowing medium in the inlet pipe is low, high pressure in the valve cavity is alleviated, the valve seat is in close fit with the valve spool, and the valve spool is low in abrasion with the boss in the valve seat and not easy to damage, so that the service lie of the valve spool is prolonged and normal working 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 lower resistance, high sealing 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 the existing valve seat in use resistance to flowing medium in the pipeline is larger, pressure is higher in the valve pocket, and valve seat cooperates defective tightness with valve core of the electromagnetic valve, the boss that cooperates with spool in the valve seat causes wearing and tearing to spool easily, damages easily the spool of solenoid valve after long-time the use, and then affects the normal operation of solenoid valve.
The model utility content
The purpose of this utility model provides a kind of solenoid valve lower resistance, high sealing valve seat, resistance to flowing medium in the pipeline is larger in use with traditional valve seat in the solution prior art, pressure is higher in the valve pocket, and valve seat cooperates defective tightness with valve core of the electromagnetic valve, 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 lower resistance, the high sealing valve seat, it is characterized in that: include the valve seat body, described valve seat middle part is provided with valve pocket, two ends be respectively equipped with into, go out 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 and the inclined-plane of annular groove bottom surface for tilting to 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 lower resistance, high sealing 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, and is easy to use, and adopting the annular groove bottom surface in valve pocket be design to the inclined-plane that inlet pipe tilts, effectively weakened the resistance of valve seat to flowing medium in the inlet pipe, make medium enter smoothly valve pocket, alleviated the interior high pressure conditions of valve pocket; And adopt the design of 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, the wearing and tearing between spool and the boss have been reduced, make the spool of solenoid valve be difficult for damaged, prolong the working life of spool, guaranteed the normal operation of solenoid valve.
