Abstract
A wellhead casing crude oil anti-theft device is composed of a body, a sieve tube, a spring, a short section, a steel ball, a ball cup, a ball cover and a connector, which is characterized in that the body has a large end and a small end, of which the part with altered diameter is arranged with the ball cup, the lower end is provided with a catch hoop joint connected with a casing gat, and the upper part is provided with a female thread connected with the thread of the connector, the lower part of the ball cup is arranged with the short section welded with the ball cup and connected with the thread of the sieve tube, the bottom of the sieve tube is welded with a convex spring seat arranged with the spring, the upper end of the spring supports the steel ball which seats on the ball cup, and the upper part of the ball cup is arranged with the ball cover connected with the thread of the body. The wellhead casing crude oil anti-theft device has simple structure, reliable anti-theft theory, simple installment and double anti-theft function that oil can not be thieved by only opening the casing gate or by opening the one-way valve without opening the connector.
Description
One, technical field
The utility model relates to a kind of lawless person of preventing steals oil at well head sleeve gate place well head sleeve pipe crude oil alarm.
Two, background technology
At present casing of oil-pumping well is antitheft generally takes 2 kinds of methods: the one, the well head Anti-theft anchor gate is installed.This is the antitheft main method of well head, but owing to the prolongation of Anti-theft anchor gate along with service time, the stolen molecule has been known principle gradually well, is easy to gate is opened: the Anti-theft anchor gate that has damages easily, makes troubles to daily management; The 2nd, the well head theft-proof box is installed.This mode can bring difficulty for to a certain extent stolen molecule stolen, but the stolen molecule is raised theft-proof box or open the continuation pilferage, and anti-theft effect is bad.
Three, summary of the invention
The purpose of this utility model provides a kind of improved well head sleeve pipe crude oil alarm, solves the problem that exists in the above-mentioned prior art.
The utility model is made up of body, screen casing, spring, pipe nipple, steel ball, ball seat, ball cover and connector, it is characterized in that body is made as big or small capitiform, the place is provided with ball seat at reducing, the bottom is provided with the clip head, be connected with sleeve gate, top is provided with box thread, is threaded with connector, is provided with pipe nipple in the bottom of ball seat, weld with ball seat, pipe nipple is threaded with screen casing, screen casing bottom weldering convex spring base, and sitting on the spring base has spring, the spring upper end heads on steel ball, steel ball is sitting on the ball seat, and ball seat top is provided with ball cover, and ball cover is threaded with body.
Ball cover is made as cylindrical, and the top internal diameter is little, and the bottom internal diameter is big, and the bottom internal diameter is greater than the external diameter of steel ball, and the ball cover periphery is provided with male thread, and top is provided with box thread.
Connector is made as cylindrical, and top is provided with box thread, and the bottom is provided with male thread, be welded with the central tube that connects by junction plate in lower central part, the central tube bottom is provided with male thread, is threaded with ball cover, upper top is welded with the stainless steel blind plate, is equipped with several pores on the blind plate.
The utility model compared with prior art has the following advantages:
1, simple in structure, antitheft principle is reliable, easy for installation.
2, have the double anti-theft function, promptly sleeve gate is opened and can not be stolen oil, and connector is not opened ball-and-seat can not steal oil.
Four, description of drawings
Accompanying drawing-structural representation of the present utility model
1-body 2-screen casing 3-spring 4-pipe nipple 5-steel ball 6-ball seat 7-ball cover 8-connector among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by body 1, screen casing 2, spring 3, pipe nipple 4, steel ball 5, ball seat 6, ball cover 7 and connector 8 are formed, it is characterized in that body 1 is made as big or small capitiform, be provided with ball seat 6 at the reducing place, the bottom is provided with the clip head, be connected with sleeve gate, top is provided with box thread, is threaded with connector 8, is provided with pipe nipple 4 in the bottom of ball seat, weld with ball seat, pipe nipple is threaded with screen casing 2, screen casing bottom weldering convex spring base, and sitting on the spring base has spring 3, the spring upper end heads on steel ball 5, steel ball is sitting on the ball seat, and ball seat top is provided with ball cover 7, and ball cover is threaded with body.
When using the utility model, load onto spring 3 at first screen casing 2 and the pipe nipple 4 of steel ball 5 below ball seat 6 connects, ball cover 7 and connector 8 and body are connected, make central tube not run into steel ball.Again body and boot band head or sleeve gate are connected and get final product, the lawless person does not make the structure of alarm clear, it is just so uneasy to think to steal oil from here, the blind plate of central tube is made as corrosion resistant plate or bores motionless alloy sheets, punching is very difficult, prevented to steal oily phenomenon effectively, if survey show casing pressure inwards the precession connector belt the inside precession of central tube, central tube just backs down ball.Oil gas is just come in from screen casing, comes out just to show pressure at pressure meter from central tube, surveyed pressure after, the connector return is got final product.
