Abstract
A kind of antitheft adjusting stop valve comprises valve body, spool, valve seat, fixed cover, seal and ball, is installed on fixed cover in the described valve body, is installed on spool, seal in the fixed cover, and seal is connected with the spool lower end, is fixed by ball.The utility model is that blind rod type is immersed oneself in structure, uses the special tool switch, has firm, durable, safety, anti-theft feature, is widely used on the oil well head equipment and similar applications.
Description
One, technical field
The utility model relates to the petroleum production wellhead equipment, and particularly a kind of petroleum production well production tree is with antitheft adjusting stop valve.
Two, background technique
Used petroleum production well production tree is generally rising stem (RS.) hand-wheel-type structure with the production valve, be connected by clip, screw thread or flange with other parts of production tree, bringing into play for petroleum production always and acting on, but it also breaks simultaneously in following shortcoming or deficiency: 1. rising stem (RS.) handwheel structure makes things convenient for anyone switch, easily cause and run oil, lose, make the generation of accidents such as well is out of hand; 2. flange, screw thread or clip connected are easy to anyone dismounting, cause damage of facilities, and well is out of hand, accidents such as oil, befouling environment are run in generation, brings the difficulty and the economic loss of management for Petroleum Production enterprise.
Three, summary of the invention
The purpose of this utility model provides a kind of improved antitheft adjusting stop valve, and it 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 avoided depositing in the above-mentioned prior art.
Antitheft adjusting stop valve described in the utility model comprises valve body, spool, valve seat, fixed cover, seal and ball, is installed on fixed cover in the valve body, is installed on spool, seal in the fixed cover, and seal is connected with the spool lower end, is fixed by ball.
Wherein, described spool outer end is for immersing oneself in structure, and its end face is three fan-shaped bowl configurations, and the inner is connected with seal, and the joint is fixed by ball.Described spool is that trapezoidal thread is connected with fixed cover.
The utility model has following advantage compared with prior art:
1, adopts dark bar structure,, have functions such as safe, antitheft owing to use tool switch;
2, employing is welded to connect, and is sturdy and durable, is difficult at will allowing the people dismantle, and for management provides strong condition, the business economic benefit improved.
