Description

Valve opening and closing mechanism for detecting air tightness of valve

Technical Field

The invention relates to the technical field of petroleum pipeline connecting valves, in particular to a valve switching mechanism for detecting the air tightness of a valve.

Background

Valves (Valve) are mechanical devices that control the flow, direction, pressure, temperature, etc. of a flowing fluid medium, and are essential components in piping systems. Valve tubing is technically the same as pumps and is often discussed as a separate category. The valve can be operated manually or by a hand wheel, a handle or a pedal, and can also be controlled to change the pressure, the temperature and the flow of the fluid medium. The valve can operate continuously or repeatedly for these changes, such as a safety valve installed in a hot water system or a steam boiler. In more sophisticated control systems, automatic control valves are employed as needed to regulate the changing set point of the flow through the pipeline from external inputs. The automatic control valve does not need manual operation and can accurately control various requirements of fluid media according to the input and the setting of the automatic control valve. The valves are further divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves and the like according to the material.

The pipeline transportation has the advantages of large, continuous, rapid, economic, safe, reliable and stable transportation amount, less investment, less occupied area and low cost, and can realize automatic control. Besides being widely used for long-distance transportation of petroleum and natural gas, the material can also be used for transporting ores, coal, building materials, chemicals, grains and the like. The pipeline transportation can save the broken joints in the water transportation or the land transportation, shorten the transportation period, reduce the transportation cost and improve the transportation efficiency. The current trend in pipeline transportation is: the caliber of the pipeline is continuously increased, and the transportation capacity is greatly improved; the transport distance of the pipeline is rapidly increased; the transportation materials are gradually expanded from fluids such as petroleum, natural gas and chemical products to non-fluids such as coal and ore. China has built a plurality of crude oil pipeline transportation lines from Daqing to Qinhuang island, Shengli oil field to Nanjing and the like.

In the in-process of petroleum pipeline transportation, pipeline can pass through the city a bit, thereby it saves the cost of transportation to transport together with city domestic wastewater, nevertheless because petroleum pipeline is close to the city, it can steal the petroleum and destroy the pipeline and cause the petroleum to reveal and pollute to appear a lot of lawless persons, and the vehicle in urban suburb is mostly heavy truck, under the long-time operation, the pipeline ageing can be accelerated constantly by vibrations to the transportation pipeline, consequently, the design can effectively prevent that the petroleum is stolen while punishment steals the lawless persons who steals the petroleum, it is very necessary to block a valve switch mechanism for detecting valve gas tightness that the petroleum reveals and reconnect the pipeline after the petroleum pipeline breaks.
