Description
Technical field
The present invention relates to butterfly valve technical field, more particularly to a kind of special butterfly valve body.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in construction, what the switch available for low pressure pipeline medium was controlled
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, a kind of valve of open and close is reached around valve shaft rotation, valve can
For controlling all kinds such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium
The flowing of fluid.It is main on pipeline to play cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Rotated around the axis of its own, so as to reach the purpose for opening and closing or adjusting.
Butterfly valve standard-sized sheet is to fully closed typically less than 90 °, and butterfly valve and butterfly bar are in itself without self-lock ability, for determining for butterfly plate
Position, will install worm reducer additional on valve rod.Butterfly valve is mainly characterized by:Operational torque is small, and installing space is small and lightweight.Butterfly
Valve easily with various combination of drive means, have good durability and reliability.Relation between the aperture and flow of butterfly valve, substantially
Upper linear ratio change.If for controlling flow, the flow resistance of its discharge characteristic and pipe arrangement also has substantial connection, such as two pipes
Road installation valve aperture, form etc. are exactly the same, and trunking loss coefficient is different, and the flow difference of valve also can be very big.If valve
Door is in the larger state of throttling amplitude, and the back side of valve plate is easily cavitated, and has the possibility for damaging valve, generally outer at 15 °
Use.When butterfly valve is in middle aperture, the opening shape that valve body is formed with butterfly plate front end is centered on valve shaft, and both sides, which are formed, to complete not
With state, the butterfly plate front end of side moves along current direction, opposite side counter-flow water direction and move, therefore, side valve body and valve
Plate shape is into like nozzle shape opening, and the similar throttling bore openings of opposite side, nozzle side is more much faster than throttling effluent speed, and the side valve that throttles
Door can produce negative pressure below, often occur that rubber seal comes off.
Valve industry, as an important step of equipment manufacture, plays very important in the national economic development
Effect.Because the domestic valve manufacture industry level of China still has certain gap, a lot of high parameters, high temperature compared with international most advanced level
The former dependence on import always of critical valves of high pressure, high pound level, such as Europe OMAL brands are always domestic valve applications industry
Main selecting object.In order to make every effort to promote Valves localization, assigned in State Council《Some meanings on accelerating development equipment manufacture
See》Afterwards, the requirement for the localization of key equipment that national departments concerned is made according to country, has successively made a series of great portions
Administration, and is taken the lead by National Development and Reform Committee, and with Machinery and Allied Products Institute together, deployment is worked out by Chinese mechanical industry federation and old China hand
The Valves localization scheme of association area Grand Equipments, and repeatedly coordinating with relevant department, nowadays Valves localization valve at home
Door industry has been built consensus.Active adoption international standard carries out product design;Absorb design structure (including the patent of foreign outstanding
Technology);Product testing, service check are strictly carried out by international standard;Absorb external vanguard technology experience and pay attention to new material
Research and popularization and application;Understand fully technical parameter and working condition of the high parameter valve products of import etc. be to speed up domesticizing into
Journey, propulsion valve product is constantly updated, and the unique channel of the production domesticization of valve is realized comprehensively.As valve industry recombinates paces
Accelerate, following industry will be competition between valve products quality safety and product brand, product is to high-tech, high parameter, resistance to
Deep-etching, high life direction are developed, only by continuous technological innovation, develop new product, undergo technological transformation, could progressively
Product technology level is improved, domestic matched with devices is met, the production domesticization of valve is realized comprehensively.China's valve manufacture industry is huge
Demand environment under, more preferable development prospect will be showed.
