Description
Technical field
It the utility model is related to safety valve technical field, more particularly to a kind of symmetric form Simple check valve.
Background technology
Safety valve is that opening and closing element is in normally off under by external force effect, when the pressure medium rise in equipment or pipeline is super
When crossing setting, by outside system discharge medium prevent the pressure medium in pipeline or equipment from exceeding the particular usage valve of specified value
Door.Safety valve belongs to automatic valve class, is mainly used for boiler, on pressure vessels and pipes, control pressure is no more than setting, to people
Body safety and equipment have run important protective effect.Note safety valve, which has to pass through pressure testing, to be used.
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, its main function is to prevent medium from falling
Flow, prevent pump and drive motor reversion, and vessel media from releasing.
Chinese valve industrial chain is numerous, but non-valve is made the country prosperous.It is overall to see that China has marched toward valve big country of the world up
Ranks, but from product quality Lai Kan China from valve power still have a very long segment difference away from.The production concentration degree of industry is low, high
The phenomenons such as the valve research and development ability that product matches is low, valve industry manufacturing technology level is low are held to still have, foreign trade
Unfavourable balance constantly expands.
The coming years will be that the high speed of valve industry is shaken the phase, and the direct result that the concussion of this high speed is brought is to cause valve
The trend to produce a polarization in cabinet brand camp expands.It is expected that the valve enterprise that a few years from now on really is able to commercially survive is exhausted
It is so more to not having.But this high speed concussion of valve industry will bring huge chance, and the result of concussion will transport market
Make more rationality.The road of the production domesticization of high-end valve is abnormal " frustration ".Basic part, which has become, restricts China's manufacturing industry to high-end
Change the short slab of development, 12 period government will continue to increase to the production domesticization dynamics of high-end equipment parts.We select herein
Take《Embodiment》In several feasibility analyses given priority to the representative valve of industry and carry out import substitution for referring to.
From analysis we can see that each sub-industry valve inlet substitutes, feasibility difference is very big, and high-end valve urgently draw by more policies
Lead and scientific research is helped.Valve industry is in the national economic development, as a manufacturing important step is prepared, plays very heavy
The effect wanted.Since the country of China valve manufacture industry level still has certain gap compared with international most advanced level, a lot of high parameters,
High temperature and pressure, the critical valves original of high pound level rely on import always, in order to make every effort to promote Valves localization, are assigned in State Council《Close
In some opinions for accelerating development equipment manufacture》Afterwards, the localization of key equipment that national departments concerned is made according to country
It is required that successively having made a series of great deployment, and taken the lead by National Development and Reform Committee, Chinese mechanical industry federation and old China hand use
Together, the Valves localization schemes of association area Grand Equipments has been worked out in deployment for Machinery and Allied Products Institute, and repeatedly and relevant department
Coordinate, nowadays Valves localization at home built consensus by valve industry.Active adoption international standard carries out product design；Absorb
The design structure of foreign outstanding；Product testing, service check are strictly carried out by international standard；Absorb external vanguard technology warp
Test the research and popularization and application for paying attention to new material；Understanding fully technical parameter and working condition of the high parameter valve products of import etc. is
Increase the proportion of domestic goods more quickly, propulsion valve product is constantly updated, and realizes the unique channel of the production domesticization of valve comprehensively.
With the quickening of valve industry restructuring paces, following industry will be between valve products quality safety and product brand
Competition, product to high-tech, high parameter, be able to bear strong corrosion, high life direction is developed, only by continuous technological innovation, open
New product is sent out, is undergone technological transformation, can just step up product technology level, meets domestic matched with devices, realizes valve comprehensively
Production domesticization.China's valve manufacture industry will show more preferable development prospect under huge demand environment.
