Abstract
An oil well anti-theft multifunction valve is provided by the utility model, which belongs to a valve used on oil wells. A ball socket is equipped in a valve body and a valve ball is provided on the ball socket. In front of the valve ball, a spring is provided and front end of the spring is mounted on a valve base. A thimble is equipped behind the ball socket through a locating sleeve. Intracavity of a union joint that is integrated with the valve body is connected with that of the valve body. The valve can only be opened with tools for special purposes, accordingly anti-theft performance is significantly improved. The utility model can be used for oil well sampling, emptying and manometric measurement with a plurality of functions. In addition, the utility model is airproof, does not cause leakage of crude oil, has proper structure, is usable and high in sampling efficiency.
Description
Technical field
The utility model provides a kind of valve, especially a kind of valve that is used on the oilfield.
Background technology
On oilfield, sample cock must be installed, to understand the firsthand information of oil well production.At present, known sample cock is made up of valve body, valve seat, spool, screw mandrel, handwheel etc.Though this valve open and close are comparatively convenient, do not have anti-theft feature, are easy to be turned on and steal crude oil by the lawless person.In addition, frequent open and close easily cause thread stripping, cause poorly sealed.Because well head pressure is generally about 1Mpa, under this pressure, poorly sealed meeting causes crude oil leakage, causes large-area environment pollution.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of oil well antitheft multipurpose valve, to improve its theftproof performance.
The utility model is to realize like this, the antitheft multipurpose valve of oil well, it has valve body, ball seat is installed in the valve body, valve ball is arranged on the ball seat, and there is spring the valve ball front, and the spring front portion is installed on the valve seat, the ball seat back is equipped with thimble by positioning sleeve, is connected with body cavity with valve body all-in-one-piece connector intracoelomic cavity.
Adopt the antitheft multipurpose valve of oil well of said structure, have only the unlatching of using specialist tools just can finish valve, therefore improved theftproof performance greatly, can be used for oil well sampling, emptying, pressure measurement, serve many purposes.Good sealing effect can not cause crude oil to reveal.Rational in infrastructure, easy to use, the sampling high efficiency.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the schematic diagram that is used for special opening tool construction of the present utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, the antitheft multipurpose valve of the oil well of the utility model, it has valve body (1), ball seat (6) is installed in the valve body, valve ball (5) is arranged on the ball seat, and there is spring (4) the valve ball front, and the spring front portion is installed on the valve seat (3), the ball seat back is equipped with thimble (8) by positioning sleeve (7), is connected with body cavity with valve body all-in-one-piece connector body (10) inner chamber.
Described connector body (10) inner chamber is eccentric circular.The inner chamber of this abnormity is convenient to the cam on the special opening instrument and the insertion of cam pole, but can be prevented from arbitrarily to insert other object Open valve.
In the front of described valve seat (3) positioning sleeve (2) is arranged.Positioning sleeve plays the effect that prevents that valve seat from withdrawing from.
As shown in Figure 2, cylindrical shell (15) is arranged on the special opening instrument, the cylindrical shell link has revolving multipurpose snap joint (12), support (16) is arranged in the cylindrical shell, be fixed with cam pole (17) on the support, be fixed with cam (11) on the cam pole, there is handle (14) the cylindrical shell outside.The internal diameter of link is corresponding with the external diameter of connector body.The oil outlet end inner surface of cylindrical shell can have screw thread, so that survey tools such as connection pressure meters.Revolving multipurpose snap joint is form of structure commonly used at present, and its concrete structure and use principle no longer describe in detail.
After being installed in the screw thread of this valve by the valve body forward outer surface on the well mouth of oil well, valve ball closely contacts with ball seat under the effect of spring (4), forms sealing, and valve is in closed condition.When the needs Open valve, the link on the special opening instrument is aimed at the connector body, it is linked together special opening instrument and this valve by revolving multipurpose snap joint.At this moment, cam, cam pole are inserted in the connector intracoelomic cavity.90 ° of angles of turning handle make it drive cam rotation, and gear pushes thimble and moves forward, and make it promote elastic force and ball seat disengaging that valve ball overcomes spring.Crude oil passes ball seat from body cavity, enters the connector intracoelomic cavity, and the oil outlet end of the cylindrical shell from the special opening instrument flows out at last, finishes sampling, emptying operation.If in the oil outlet end of cylindrical shell, install survey tools such as pressure meter in advance, then can finish operations such as pressure measurement.
Valve seat (3), positioning sleeve (7), support (16) are tower structure, so that crude oil is mobile.Spring (9) can be arranged between thimble and the positioning sleeve.Sealing ring (13) is arranged, the sealing after can realizing cylindrical shell and the connector body being connected in the cylindrical shell on the special opening instrument.
Claims (3)
1, the antitheft multipurpose valve of oil well, it is characterized in that, it has valve body (1), ball seat (6) is installed in the valve body, valve ball (5) is arranged on the ball seat, and there is spring (4) the valve ball front, and the spring front portion is installed on the valve seat (3), the ball seat back is equipped with thimble (8) by positioning sleeve (7), is connected with body cavity with valve body all-in-one-piece connector body (10) inner chamber.
2, the antitheft multipurpose valve of oil well as claimed in claim 1 is characterized in that, described connector body (10) inner chamber is eccentric circular.
3, the antitheft multipurpose valve of oil well as claimed in claim 1 is characterized in that, in the front of described valve seat (3) positioning sleeve (2) is arranged.
