Abstract

A stop valve comprises a valve core, a valve body, a seal element and an end cover, wherein the valve core is mounted in the valve body, the seal element is mounted on the valve core, and the end cover is mounted at one end of the valve body. The stop valve provided by the utility model has the advantages that oil and the valve are prevented from being stolen, the environment pollution incidents are prevented, the operation cost of an enterprise is reduced, the welding, screw thread and buckle connection is adopted, the structure is simple, the stop valve is sturdy and durable and is not easy to be stolen when the welding connection is adopted, and the management is facilitated, thereby being widely applicable to production trees at the mouths of producing wells.

Description

Stop valve
Technical field
The utility model relates to the oil exploitation well head and uses valve, and particularly a kind of oil exploitation well production tree is used stop valve.
Background technology
Used oil exploitation well production tree is generally rising stem (RS.) hand wheel type structure with production valve, sample valve; Be connected by clip, screw thread or flange with other parts of production tree; Bringing into play for oil exploitation always and acting on; But it also breaks in following shortcoming or deficiency simultaneously: 1. rising stem (RS.) handwheel structure makes things convenient for anyone switch, is prone to cause run oil, lose, and makes the generation of accidents such as well is out of hand; 2. flange, screw thread or clamp connection are easy to anyone dismounting, cause damage of facilities, and well is out of hand, accidents such as oil, contaminated environment are run in generation, brings the difficulty and the economic loss of management for Petroleum Production enterprise.
Summary of the invention
The purpose of the utility model provides a kind of improved stop valve, adopts dark bar, by the structure of special tool switch, with other parts for being welded to connect, the shortcoming or the deficiency that overcome effectively or avoid depositing in the above-mentioned prior art.
The described stop valve of the utility model comprises spool, valve body, seal, end cap.Be installed on spool in the said valve body, seal is installed on the spool, an end of valve body is equipped with end cap.
Wherein, said spool outer end is plush copper or immerses oneself in structure.Said spool outer face is plush copper or the bowl configurations that triangular structure is arranged.Said end cap is screwed connection or destructive structure.
The utility model has following advantage compared with prior art:
1, adopts the special tool switch, prevent that stolen from stealing the valve incident and the environment pollution incident takes place, reduce the enterprise operation cost;
2, adopt welding, screwed connection, simple in structure, adopt when being welded to connect sturdy and durablely, be difficult for stolenly, be beneficial to management.
3, use is many, not only as stop valve, also can be used as sample valve.
