Description
Technical field
The present invention relates to valve technology field, is specifically related to a kind of water pressure test and blocks up valve.
Background technology
The water pressure test is blocked up valve and is installed in the pipeline system for needing pressure testing, by valve body, valve deck, closure plate, support plate, fore-set,
Diversion pipe, pressing plate, seal, fastener etc. form, and when pipeline needs pressure testing, closure plate, support plate and fore-set are placed in valve body
It is interior, with fore-set pretension closure plate, and valve is assembled and is completed, recycle the pressure medium during pipeline pressure testing closure plate is formed with valve body
Sealing pair, to realize the purpose of system pipeline pipe section pressure test, after the completion of pressure testing experiment, valve is disintegrated, takes out closure plate, support plate
And fore-set, diversion pipe is put into, and diversion pipe is compressed with pressing plate, prevention diversion pipe is as the fluctuation of system media pressure is in valve
Concussion, then valve is assembled and is completed, valve is blocked up at this time to be used as one section of pipeline in system.
Such stifled valve is disadvantageous in that：, it is necessary to mold and cast when 1. valve body, valve deck are casting, production cost
High, cycle length；2. valve body, valve deck are forging, blank dimension is big, production cost is high, at the same open die forging blank difficulty of processing it is big,
Machining cutting output is big, production cycle length；3. valve body sealing surface needs built-up welding stainless steel or hard alloy steel, for manufacturer
Manufacture level there are certain requirements, and increase product manufacture cost and the production cycle；4. stifled valve disintegrates and is equipped with certain difficulty
Degree, and stifled valve disintegration is time-consuming very long with assembling, and more inconvenience is brought to user's use；5. it need to determine to be situated between during pressure testing during stifled valve installation
Mass flow is flowed to medium during normal operation, and the flow direction of two states needs to be determined according to the installation site of stifled valve, sometimes two states
Medium flow to it is identical, sometimes on the contrary, so either initial installation or assembling when using are required to more professional technology people
Member is instructed；6. stifled valve is difficult to control and detects whether correctly to install when loading closure plate, once finding stifled during the water pressure test
, it is necessary to stop testing when valve does not play the role of turning off system pipeline, strip inspection assembles stifled valve again again, while user needs weight
Pressurized test newly is carried out to system, this will cause very big economic loss to user, and the test period lengthens.
The content of the invention
