Abstract
The invention discloses a manual operation pressure relief device which comprises an operation support and a connecting support. The operation support and the connecting support are mutually connected in a rotary mode. A detachable connecting protruding block is arranged at the bottom of the connecting support. A lock stopping ring and a pressure relief bar are arranged at the bottom of the connecting protruding block. According to the operation support and the connecting support in movable connection, a handle can be folded completely, space occupied by the device is greatly reduced, the device is easy to store and applicable to field drilling operation. In addition, due to adoption of the detachable connecting protruding block, a user can choose pressure relief bars in different length according to different valves needing pressure relief and therefore, adaptability is greatly improved.
Description
Technical field
The present invention relates to a kind of oil drilling machinery, or rather, is a kind of manual pressure relief device.
Background technology
In the process of the experimental drilling of oil, need manually to judge according to pressure meter the pressure of down-hole, in a single day if exceed preset value, must manually carry out pressure release.The handle of existing relief valve need to occupy larger space for fixing horizontally set, brings very inconvenience for open-air drillng operation.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of manual pressure relief device is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of manual pressure relief device, described manual pressure relief device comprises operation support and a connection bracket, described connection bracket is connected with described operation bracket-rotatable movingly, the bottom of described connection bracket is provided with a dismountable connection projection, and the bottom of described connection projection is provided with a locking circle and pressure release rod.
As preferred embodiment of the present invention, described operation support comprises one handle and a pair of operation flange, the middle part of described operation flange is provided with the first connecting through hole, be provided with one between the afterbody of operation flange and connect pin rod, described connection bracket comprises a pair of flange connector, it is prominent that the top of described flange connector is provided with connection button, is provided with a spacing pin rod between the middle part of flange connector, and described the first connecting through hole is connected rotationally with described connection button is prominent.
Operation support and connection bracket that manual pressure relief device utilization of the present invention is flexibly connected make the handle can be fully folding, have greatly dwindled its space that need to occupy, and easily take in, and are fit to open-air drillng operation.In addition, owing to adopting dismountable connection projection, the user can select the pressure release rod of different length according to the difference of need relief valve, and applicability has obtained improving greatly.
