An Easy-to-Adjust Petroleum Mechanical Valve

Abstract

The invention relates to the technical field of mechanical valves, in particular to a petroleum mechanical valve that is easy to adjust, including a main body mechanism, on which an adjustment mechanism rotates; on the adjustment mechanism, a sliding limit mechanism; on the adjustment mechanism, An interference mechanism is installed; the interference mechanism is connected with a sealing mechanism; the main body mechanism is connected with a lubricating mechanism; when the valve needs to be opened, the limit mechanism can be pulled by hand first, and then the limit mechanism can be opened from the inside of the adjustment mechanism. Slide out, and then turn the limit mechanism, so that the limit mechanism is engaged inside the main mechanism, which is convenient for the operator to rotate the adjustment mechanism and also helps to prevent mis-rotation; when the adjustment mechanism slides in the main mechanism, it will squeeze the conflicting mechanism Pressure, and then the interference mechanism can discharge gas into the sealing mechanism when it slides inside the main mechanism, and then seal the main mechanism when the sealing mechanism expands, thereby helping to prevent oil leakage when the valve is not opened.

Description

technical field [0001] The invention relates to the technical field of mechanical valves, in particular to an easy-to-adjust petroleum mechanical valve. Background technique [0002] Valves are an indispensable and important part of petroleum pipeline systems and are widely used in oil transportation systems. In the prior art, petroleum mechanical valves are commonly used equipment during the transportation of petroleum through pipelines. [0003] However, due to the large number of valves used in an oil pipeline, when the sealing effect of the connection between the valve and the oil pipeline is poor, some valves may leak, and operators need to repair the valves and replace parts , to a certain extent, it is not conducive to improving the use effect of the valve; in addition, during the use of the valve, if the operator turns the handwheel by mistake, it is easy to affect the opening and closing effect of the valve, and there are certain defects in use, which is not conduc...
