Description
Technical field
The utility model relates to a kind of valve, relates in particular to the Pilot operated check valve of regulating the pressure function that has on a kind of pipeline that is installed in water supply/atmospheric pressure storage tank.
Background technique
At present in the production process in metallurgy, chemical industry, light industry and machinery field, often be provided with the water system that the band pressure water source is provided to manufacturing mechanism separately, this water system utilizes the pattern of Caes, absorption energy, absorption impact energy to ensure that suction booster does not have the pressure surge operation.
The operating mode of the water system that the band pressure water source is provided under the prior art is as follows: the water pump of water system will not have press water and will get to storage tank, storage tank separates the air water medium again, and guarantor's positive compression air can not enter water pipe, thereby ensure that whole water-pressurization system normally moves, and provides the band pressure water source by pipeline at last.
Yet the diaphragm type storage tank cost height under the prior art, and must be dedicated devices, equipment are adjusted to use and are made troubles, and acquisition expenses costliness again.Because the original structure of storage tank is processed, operation standard is low, fault is more, isolate with the alternately contact of barrier film steam, expansion, distortion, be easy to corrosion and damage, therefore cause resource, manpower waste, at present in industry, also do not address this problem well, having caused making production, maintenance cost raising, labor waste, also is like this in the world.
Though some unit does not use the diaphragm type storage tank; use other common storage tank instead; but sometimes because reasons such as shutdown or external pipe leakages; make the pressure drop of water system pipeline to being lower than tank inner pressure; the storage tank internal air pressure can leak or enter water supply line, causes gas to enter water supply pressurization system pipeline, and the fault that water system can't pressurized water supply takes place; sometimes also can not find reason for the moment, cause cutting off the water for a long time, drive on boldly even the heat load device damage.
Through long overhaul of the equipments and on-the-spot practical experience, we find, the water system pipeline pressure drop of storage tank is to being lower than tank inner pressure, the storage tank internal air pressure leaks or enters water supply line, cause gas to enter water supply pressurization system pipeline, the fault that water system can't pressurized water supply takes place, except the design problem of storage tank itself, also relevant with the valve on the storage tank pipeline, valve under the technology only is to open or close function now, being used in common only being used to, to store the storage tank of medium no problem really, but common valve can't be tackled the storage tank mode of operation that needs the band pressure water source, thereby the water system pipeline pressure drop that has caused storage tank is to being lower than tank inner pressure, and the storage tank internal air pressure leaks or enters water supply line, causes gas to enter these problems of water supply pressurization system pipeline.
The model utility content
In sum; for the common valve that solves under the prior art can't be tackled the storage tank mode of operation that needs the band pressure water source; thereby the water system pipeline pressure drop that has caused storage tank is to being lower than tank inner pressure; the storage tank internal air pressure leaks or enters water supply line; cause gas to enter these problems of water supply pressurization system pipeline; we provide a kind of pressure regulating type Pilot operated check valve that is applied to the pressure of supply water storage tank; valve mechanism by redesign; make it can be according to different water-pressurization systems; adjusting is set to the force value that needs; having solved water-pressurization system can be because of shutdown; or the water system pipeline pressure that causes of reason such as external pipe leakage drops to or is lower than the problem of tank inner pressure; and the storage tank internal air pressure can not leak or enter water supply line; cause supplying water the pressurization system pipeline because of entering gas; the problem of the fault that water system can't pressurized water supply takes place, and concrete structure of the present utility model is as described below:
