It is that A planes can cause various defects quickly in the presence of pressure and soda acid, influences sealing property, ultimately results in whole defective valve.
Accordingly, it would be desirable to be improved to prior art, to improve the service life of valve seat, technology difficulty is reduced.
Utility model content
To solve the deficiencies in the prior art, the utility model provides a kind of valve seat be easy to and safeguard.This is easy to what is safeguarded
Valve seat is sealed with trapezoidal seal washer, the sealing of replacement seal face, it is easy to is changed and is safeguarded, reduces the difficulty of construction technology.
A kind of valve seat for being easy to safeguard, including discoidal pedestal, the pedestal is axially disposed circulation passage, described
One end face of pedestal is provided with sealing surface, and the circulation passage runs through the sealing surface, pad is provided with the sealing surface
Ring recess, is provided with seal washer in the gasket groove, and the gasket groove is located at the outside of the circulation passage.
Further, the seal washer includes annular body and the radial convex being arranged on the annular body lateral surface
Rise, groove is provided with the radial protrusion.
In the above-mentioned technical solutions, when seal washer reaches service life to be needed to change, by destroying radial convex
Rise, expose groove, then by groove and instrument, in that context it may be convenient to stick up seal washer and changed and safeguarded.Enter one
Step, the seal washer is removably embedded in the gasket groove.
Further, the section of the annular body is trapezoidal.
Further, the upper surface of the annular body is parallel with the sealing surface with lower surface.
Further, width of the width of the upper surface of the annular body less than the lower surface of the annular body.
Further, the lower surface of the annular body is pressed on the pedestal.
Further, the upper surface of the annular body is higher than the sealing surface.
Further, the sealing surface is more than 60 ° with the angle of the axis of the circulation passage.
Further, the upper surface of the radial protrusion maintains an equal level with the upper surface of the annular body, the radial convex
The lower surface risen maintains an equal level with the lower surface of the annular body.
The valve seat for being easy to safeguard provided by the utility model improves sealing structure by setting trapezoidal seal washer, with
Reduce the difficulty of construction.Also, sealing structure can be changed by destroying, it is easy to the maintenance of device.
The valve seat for being easy to safeguard provided by the utility model has the advantages that：
1st, service life is high, and manufacturing process difficulty is low；
2nd, A flat seals are not used, trapezoidal seal washer sealing is changed to, V-groove are cut with the sealing plane of sealing gasket,
The contact of plane is reduced, is that this specially develops acid and alkali-resistance, wearability very while influence of the impurity to sealing in medium can be avoided
Good special (purpose) rubber material；
3rd, can carry out brokenly ring conveniently to take out seal washer to local when seal washer reaches service life.

Specific embodiment
Principle of the present utility model and feature are described below, illustrated embodiment is served only for explaining the utility model,
It is not intended to limit scope of the present utility model.
In a detailed embodiment, as shown in Figure 2,3, 4, a kind of valve seat for being easy to safeguard, including discoidal base
Seat 1 a, end face of pedestal 1 is provided with sealing surface 3, and pedestal 1 is axially disposed circulation passage 2, and circulation passage 2 is through sealing
Face 3, sealing surface 3 is more than 60 ° with the angle of the axis of circulation passage 2.
As shown in Figure 2,3, 4, gasket groove is provided with sealing surface 3, seal washer 4 is provided with gasket groove, sealed
Packing ring 4 is removably embedded in gasket groove, also, gasket groove is located at the outside of circulation passage 2.Seal washer 4 includes ring-type
Main body 401 and the radial protrusion 402 being arranged on the lateral surface of annular body 401, groove is provided with radial protrusion 402
403.The upper surface of radial protrusion 402 maintains an equal level with the upper surface of annular body 401, lower surface and the ring-type master of radial protrusion 402
