Oil outlet valve auxiliary device for petroleum and petrochemical based on stability improvement

Abstract

The invention provides an oil outlet valve auxiliary device for petroleum and petrochemical based on stability improvement. The oil outlet valve auxiliary device comprises a valve body, a fixing part is fixedly mounted on the inner wall of the valve body, a buffer spring is mounted on the upper side of the fixing part, a buffering component is fixedly mounted at the upper end of the buffer spring, a buffering assembly is installed on the upper side of the buffering component, and a movable rod and a movable connecting rod are installed on the lower side of the buffering component. According to the oil outlet valve auxiliary device for petroleum and petrochemical based on stability improvement, the movable rod is used for pushing a mounting plate to extrude a buffer air bag, so that impact force generated by an oil outlet pipe is effectively relieved, the impact force borne by the buffering assembly is further relieved by arranging a movable buffer block and a mounting spring, and meanwhile, vibration generated when high-pressure liquid passing through the valve body flows is buffered, large impact of the high-pressure liquid on the valve is avoided, and the service life of equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to an auxiliary device for oil outlet valves used in petroleum and petrochemical industries based on improved stability. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex There are various types and specifications of valves used in the automatic control system. [0003] Nowadays, valves can be...

Problems solved by technology

[0003] Nowadays, valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. At present, there is an oil outlet valve that is in use During the process, due to the direct impact of the high-pressure liquid on the valve core during oil circulation, it is easy to cause wear and tear on the equipment for a long time, and at the same time reduce the service life of the valve, and the traditional equipment has problems such as unsmooth commutation and unreliable performance. There are deficiencies and cannot meet the needs of users. Therefore, it is necessary to further improve
