Abstract
The utility model discloses a manual pressure relief device comprising an operating support and a connecting support which are connected with each other in a rotatable manner, a dismountable connecting boss is arranged at the bottom of the connecting support, and a locking ring and a pressure relief rod are arranged at the bottom of the connecting boss. The operating support and the connecting support which are connected with each other in a rotatable manner are utilized to enable a handle to be fully folded, so that the occupying space is greatly reduced, the manual pressure relief device is easy to accommodate and is suitable for field drilling operation; and besides, dismountable connecting boss is adopted, so that users can choose pressure relief rods different in length according to different pressure relief valves, and applicability is greatly improved.
Description
Technical Field
The utility model relates to an oil drilling machinery, more exactly, is a manual pressure relief device.
Background
In the process of experimental drilling and production of petroleum, the pressure in the well is judged manually according to a pressure gauge, and once the pressure exceeds a preset value, the pressure is released manually. The handle of the conventional pressure release valve is fixedly and transversely arranged, so that a large space is required to be occupied, and great inconvenience is brought to field drilling operation.
Disclosure of Invention
The utility model discloses solve the technical problem that prior art exists mainly to a manual pressure relief device is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a manual pressure relief device, manual pressure relief device contain an operation support and a linking bridge, linking bridge with operation support rotationally be connected, linking bridge's bottom be equipped with a detachable connection lug, the bottom of connection lug be equipped with a locking ring and a pressure release stick.
As the preferred embodiment of the present invention, the operation bracket comprises a handle and a pair of operation flanges, the middle of the operation flange is provided with a first connecting hole, a connecting pin rod is arranged between the tail of the operation flange, the connection bracket comprises a pair of connecting flanges, the top of the connecting flange is provided with a connecting button protrusion, a limiting pin rod is arranged between the middle of the connecting flange, and the first connecting hole is rotatably connected with the connecting button protrusion.
The utility model discloses a manual pressure relief device utilizes swing joint's operation support and linking bridge for the handle can be folded completely, has reduced the space that its needs occupied greatly, accomodates easily, is fit for field drilling operation. In addition, due to the fact that the detachable connecting convex blocks are adopted, users can select the pressure release rods with different lengths according to the difference of the pressure release valves, and the applicability is greatly improved.
