Preferable scheme, the Top fastening screw head are that side is hexagonal structure, and top is sphere.
Further preferred scheme, the Top fastening screw and the length of thread engagement of left closure plate are more than right closure plate, left closure plate
The gap being close to respectively behind fracture right side, left side.
A kind of water pressure test block up valve implementation process be：
The valve body both ends that valve is blocked up in the water pressure test are welded on pipeline with Type of Welding, ensure stability on pipeline and close
Feng Xing；Load right closure plate, left closure plate in hydrostatic test, tighten Top fastening screw, compressing O-ring seal makes right closure plate and valve body complete
It is hermetically sealed；Dismountable right closure plate, left closure plate after the water pressure test, load baffle liner, used as pipeline, do not influence follow-up
Pipeline fluid transportation work.
By using such scheme, valve is blocked up in a kind of water pressure test of the present utility model, and it has technical effect that：
1st, the utility model is achieved that the hydrostatic test of pipeline, it is tied by only changing closure plate under hydrostatic test
Structure is simple, and it is convenient to change, and cost is cheap.
2nd, the utility model is in daily operation process, it is only necessary to by closure plate be replaced by baffle liner can complete stifled valve to
The conversion of pipeline, its is simple in construction, novel, disclosure satisfy that long range the daily water-pressure sealed detection and can of pipeline meet it is daily
Job requirements.
3rd, the stifled valve of the utility model completion needs only to worker's dismounting closure plate to normal pipeline diversification in role and led
Stream circle, its labor intensity is low, takes less, whole production cost further reduces.
