Abstract

The invention discloses an automatic hydraulic petroleum safety valve and relates to a hydraulically-controlled automatic safety valve. The valve consists of a valve body and a hydraulic cylinder and is characterized in that the valve body is provided with a petroleum inlet and a petroleum outlet, and a valve wall opposite to the petroleum inlet is provided with a through hole. A support is mounted on the valve body, the hydraulic cylinder is mounted in the support, a piston rod of the hydraulic cylinder penetrates through the through hole of the valve body to enter the valve body, and a plug is mounted in the front of the piston rod. The hydraulic cylinder is connected with an external hydraulic system through a pipeline, and the inner wall of the valve body is coated with a polyurethane coating. The automatic hydraulic petroleum safety valve has the advantages of novel structure, simplicity and convenience in processing, convenience in use, safety, reliability and the like and is a novel automatic hydraulic petroleum safety valve integrating economy and practicality.

Description

technical field [0001] The hydraulic petroleum automatic safety valve of the present invention relates to a hydraulic control automatic safety valve. Background technique [0002] The situation of pipeline leakage often occurs now, and the leakage of oil will bring a lot of inconvenience to people's daily life and production. When a leak occurs, the first thing to do is to block the pipeline to prevent the oil in the pipeline from leaking. We will have a device that can timely plugging like this, aim at the problems existing in the above-mentioned prior art, research and design a kind of novel hydraulic oil automatic safety valve, thereby overcome the existing problems in the prior art is very necessary. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the invention is to study and design a novel hydraulic petroleum automatic safety valve. It is used to block the leaking pipeline in time when the pipelin...
