Abstract
A kind of novel high-pressure valve threaded connection safety device, comprising: novel high-pressure valve (1), head protector (2), connector sleeve (3), central tube (4)；It is characterized in that: the central tube (4) passes through from the center of connector sleeve (3), the upper external screw thread of central tube (4) is connect with the lower end centre bore internal screw thread of novel high-pressure valve (1), connector sleeve (3) is connect with the lower end external screw thread of novel high-pressure valve (1), head protector (2) is covered in the lower end of novel high-pressure valve (1), positioned at the top of connector sleeve (3), connector sleeve (3) are covered.The beneficial effects of the utility model are: being suitable for being threadedly coupled high pressure valve for installing the operations such as pressure gauge, water sampling, emptying.In process of production, it in the case that the leakage of central tube screw thread thorn is even failed, avoids high-pressure medium from directly piercing on operator or the person's of patrolling body, prevents valve from flying out and casualty accident occurs, ensure oilfield safety production.
Description
Technical field
The utility model relates to oil extraction in oil field engineering technology, specifically a kind of novel high-pressure valve is threadedly coupled safety
Device.
Background technique
In oil field injection and extraction development process, need largely to be threadedly coupled high pressure valve for install pressure gauge, water sampling,
The operations such as emptying.High pressure valve input end is connected on the external screw thread of production procedure pipe nipple, and outlet end connection pressure gauge connects
Head or sampling emptying elbow.Declined by the external screw thread that corrosive media is influenced pipe nipple by corrosion strength in production process, is being opened
The variation of valve inside and outside differential pressure greatly, is influenced by the unbalanced active force of operator in addition when closing valve, can be gone out pipe nipple and be showed screw thread thorn
Leakage even valve flies out casualty accident.Therefore, threaded connection is improved eliminate safe hidden trouble it is necessary.
Summary of the invention
The purpose of this utility model designs a kind of novel high-pressure valve spiral shell aiming at drawbacks described above of the existing technology
Line connecting safety device.
The utility model is realized by following technical proposals:
The utility model includes: novel high-pressure valve, head protector, connector sleeve, central tube；It is characterized in that: the central tube
Pass through from the center of connector sleeve, the upper external screw thread of central tube is connect with the lower end centre bore internal screw thread of novel high-pressure valve, even
Female connector is connect with the lower end external screw thread of novel high-pressure valve, protects cap sleeve in the lower end of novel high-pressure valve, positioned at connector sleeve
Connector sleeve is covered on top.
A kind of above-mentioned novel high-pressure valve is threadedly coupled the centre bore of the input end of the novel high-pressure valve in safety device
Equipped with internal screw thread, outside is equipped with external screw thread.
It is leather cup shape that a kind of above-mentioned novel high-pressure valve, which is threadedly coupled the head protector in safety device, and center is equipped with through-hole,
It is made of oil-resistant rubber material.
A kind of above-mentioned novel high-pressure valve is threadedly coupled the connector sleeve centre bore lower part in safety device and is equipped with ring-shaped step,
Top is equipped with internal screw thread.
It is steel high pressure seamless pipe that a kind of above-mentioned novel high-pressure valve, which is threadedly coupled the central tube in safety device, and centre is equipped with
One ring-shaped step, top are equipped with external screw thread, and lower end welds together with pipeline.
The beneficial effects of the utility model are: being suitable for being threadedly coupled high pressure valve for installing pressure gauge, water sampling, putting
The operations such as sky.In process of production, in the case that the leakage of central tube screw thread thorn is even failed, high-pressure medium is avoided directly to pierce operation
It on person or the person's of patrolling body, prevents valve from flying out and casualty accident occurs, ensure oilfield safety production.

Specific embodiment
The implementation of the utility model is further elaborated with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of novel high-pressure valve is threadedly coupled safety device by novel high-pressure valve 1, head protector
2, connector sleeve 3, central tube 4 form；It is characterized in that: the centre bore of the input end of the novel high-pressure valve 1 is equipped with external screw thread, outside
Portion is equipped with external screw thread, and the central tube 4 passes through from the center of connector sleeve 3, and central tube 4 is upper made of steel high pressure seamless pipe material
End external screw thread is connect with the lower end centre bore internal screw thread of novel high-pressure valve 1,3 centre bore lower annular step of connector sleeve and center
4 intermediate annular step of pipe is hooked together, and the upper end internal screw thread of connector sleeve 3 is connect with the lower end external screw thread of novel high-pressure valve 1,
Using lower end of 2 sets of the leather cup shape head protector in novel high-pressure valve 1 made of oil-resistant rubber material, positioned at the top of connector sleeve 3,
Connector sleeve 3 is covered.
