Abstract
The invention discloses an internal spray-resisting burglar alarm of a sleeve pipe, and belongs to spray-resisting devices. The internal spray-resisting burglar alarm of the sleeve pipe is composed of a connector body, an annular supporting disk, a floating ring and a guide centering ring, the annular supporting disk is fixed on the lower portion of the connector body, the floating ring is sleeved on the portion, below the annular supporting disk, of the connector body in a clearance-fit mode, the guiding centering ring is fixed on the portion, below the floating ring, of the connector body, more than one balanced hole is formed in the ring body of the annular supporting disk, and a sealing ring is embedded on the ring surface of the periphery of the ring body; the diameter of the sealing ring is larger than the diameter of the annular supporting disk, and a groove is formed in the ring circumference of the sealing ring. The internal spray-resisting burglar alarm of the sleeve pipe is reasonable in structural design and capable of improving the sealing ring, enabling the sealing effect to be better and solving the problem of outward leakage of oil and gas thoroughly. At the same time, the internal spray-resisting burglar alarm is arranged inside an oil well sleeve pipe, so that the occurrence of the phenomenon that the oil well is damaged is effectively prevented, the length of the alarm body is designed to be prolonged, and therefore the occurrence of the freezing phenomenon is effectively prevented.
Description
Technical field
The invention belongs to the automatic closing passage blowout hookup of hydroful in the oil well casing, particularly relate to blowout prevention alarm in a kind of sleeve pipe.
Background technology
Near the main line of oil field stolen molecule wildness often drives a well and drains the oil at present, brings about great losses for the resource of country.The producing well that has is because the frequency that pump efficiency is bad or the sleeve pipe liquid level rises and impels the lawless person to drain the oil more, they often take to stop evening well, on carry polished rod or cut off the height that methods such as polished rod improve the liquid level in the sleeve pipe, reach the purpose of draining the oil more, draining the oil fast.In order to solve the problem of stolen, though at present at the aboveground anti-theft device of also having installed, owing to the reason that is mounted in well head, it is antifreeze, anti-destructive is poor, and to making the non-constant of anti-theft effect, thief still can be stolen the crude oil in the sleeve pipe, and complex structure, the cost height.Conventional device has solved the problems referred to above, but because its knot design is unreasonable, device is short application life, the cost of production height, and the joint ring of existing apparatus in addition, its anchor ring is shiny surface, and sealing effectiveness is bad, and application life is short.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and blowout prevention alarm in a kind of sleeve pipe is provided.
Blowout prevention alarm in the sleeve pipe of the present invention, be to be constituted by joint body, annular support plate, float ring and guiding centering ring, fixed annular support plate in the joint body middle and lower part, on the joint body below the annular support plate matched in clearance suit float ring, joint body below the float ring has been fixed the guiding centering ring, the joint ring that has been provided with on the periphery anchor ring of more than one balance pipe, its ring body setting-in at the ring body of annular support plate; The diameter of joint ring is greater than the diameter of annular support plate, and has groove in the ring week of joint ring.
As a further improvement on the present invention, inlayed diaphragm seal at inwall and the upper surface of float ring.
As a further improvement on the present invention, at the external surface of joint body, the inner surface of diaphragm seal chromium coating is arranged all, its thickness is for being 50～800 μ m.
Blowout prevention alarm in the sleeve pipe of the present invention, reasonable in design, joint ring is improved, make sealing effectiveness better, thoroughly solved the problem that oil, gas leak, simultaneously, this device is installed in the oil well casing, prevented from destroying the generation of oil well phenomenon effectively, design has lengthened the length of body, prevents from freezing the generation of phenomenon effectively.
Description of drawings
Fig. 1 is the structural representation of blowout prevention alarm in the sleeve pipe of the present invention;
Fig. 2 is the structural representation of annular support plate 2;
Fig. 3 is the structural representation of guiding centering ring 4.
The specific embodiment
Blowout prevention alarm in the sleeve pipe of the present invention, be to be constituted by joint body 1, annular support plate 2, float ring 3 and guiding centering ring 4, wherein joint body 1 can lengthen as required, and fixed annular support plate 2 in joint body 1 middle and lower part, on the joint body 1 below the annular support plate 2 the matched in clearance suit float ring 3, joint body 1 below float ring 3 has been fixed guiding centering ring 4, the joint ring 6 that has been provided with on the periphery anchor ring of more than one balance pipe 5, its ring body setting-in at the ring body of annular support plate 2; The diameter of joint ring 6 is greater than the diameter of annular support plate 2, and has groove 8 in the ring week of joint ring 6.Its groove 8 can be according to actual needs, and is arranged side by side for a plurality of grooves, forms multiple-sealedly, guaranteed sealing effectiveness.
This device is the opening or closing of principle implement device passage of utilizing float buoyancy, and has therefore inlayed diaphragm seal 7 at inwall and the upper surface of float ring 3.
This device all has chromium coating 9 at the external surface of joint body 1, the inner surface of diaphragm seal 7, and its thickness is for being 50～800 μ m.
The edge that guiding centering ring 4 is is continuous convex-concave structure, forms petal-shaped, is 1 * 45 ° of cusped edge abate specifically, and liquid can be circulated.
