Abstract

The invention discloses a ball valve for top assembling. The ball valve comprises a valve body, a valve cover, a valve rod, a ball body and a valve seat, wherein the valve seat is mounted in a valve seat supporting body, and an elastic element extending into the valve seat supporting body is arranged on the valve seat; a spacer pin is fixedly arranged on the side, close to the valve cover, of the valve seat supporting body and matched with a hole in the valve cover to be positioned. The ball valve has the advantages of being reasonable in structure, convenient to maintain, easy to operate and large in operation space, and the function of the elastic element is not affected.

Description

A kind of upper-mounting type ball valve
Technical field
The present invention relates to a kind of upper-mounting type ball valve.
Background technique
During upper-mounting type ball valve on-line maintenance, spheroid be taken out, valve seat must be made to both sides yielding place certain space.In prior art, adopt cam pin pole poked type structure for small dimension (DN≤80), problem is the insufficient strength of pin, easy-rupturing and distortion, because the resistance that will overcome elastic element when stirring; Large gauge (DN≤100) adopts thread bush structure, and problem is Long-Time Service, and particularly in high temperature media, deformed threads, corrosion and jam, cannot action.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, upper-mounting type ball valve easy to maintenance.
Technical solution of the present invention is:
A kind of upper-mounting type ball valve, comprise valve body, valve gap, valve rod, spheroid, valve seat, it is characterized in that: valve seat is arranged in valve seat support, valve seat is arranged the elastic element stretched in valve seat support, the nearly valve gap side of valve seat support is fixed with position limit pin, and position limit pin coordinates with the hole on valve gap locates;
When removing valve gap maintenance, promote position limit pin to two ends, make valve seat leave spheroid, take out spheroid, valve seat.
The present invention is rational in infrastructure, easy to maintenance, operates light, and operating space is large, the not function of influence elastane element.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
A kind of upper-mounting type ball valve, comprise valve body 1, valve gap 2, valve rod 3, spheroid 4, valve seat 5, valve seat is arranged in valve seat support 6, valve seat is arranged the elastic element 7 stretched in valve seat support, the nearly valve gap side of valve seat support is fixed with position limit pin 8, and position limit pin coordinates with the hole on valve gap locates;
When removing valve gap maintenance, promote position limit pin to two ends, make valve seat leave spheroid, take out spheroid, valve seat.
