Abstract
The invention relates to a pressurizing test bed for leak hunt of a butterfly valve, which is characterized by mainly comprising a frame-shaped stand, a pressure head, a water tank and a hydraulic system, wherein the top of the stand is fixedly connected with an oil tank in the hydraulic system, the upper part of the oil tank is fixed with an oil pump communicated with the oil tank, the oil tank of the hydraulic system is arranged on the top of the stand, an oil cylinder piston is connected with the pressure head, both sides of the pressure head are slidingly connected with a guide rail on the inner side of upright columns of the stand, the lower part of the stand, corresponding to the pressure head, is provided with a cavity type workbench, the excircle of the workbench is matched with the inner caliber of a butterfly valve to be tested, and a cavity of the workbench is connected with the water tank through a water pipe and a stop valve. The invention has the advantages of simple operation of the test bed and accurate data detection, and can be used for inspecting the produced butterfly valves one by one, thereby greatly improving the exfactory pass rate of the butterfly valves.
Description
Technical field
The invention belongs to the valve detection device, relate in particular to a kind of butterfly valve bulge test platform that leaks hunting.
Background technology
The method that butterfly valve leaks hunting adopts manual detection always.That is, butterfly valve to be measured is put in the groove that is filled with water,, observes butterfly valve and whether leak by suppressing.This kind method is unsuitable for large-scale production, especially for large-diameter butterfly valve, detect very inconvenience, and the data of leaking hunting can't be grasped accurately.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of butterfly valve bulge test platform that leaks hunting is provided, be very suitable for leaking hunting of large-diameter butterfly valve and suppress experiment, the data of leaking hunting are grasped accurately.
The present invention for achieving the above object, by the following technical solutions: a kind of butterfly valve bulge test platform that leaks hunting, it is characterized in that: mainly by stirrup frame, pressure head, water pot, hydraulic system constitutes, fuel tank in the affixed hydraulic system of described frame top, fuel tank top is fixed with the oil pump that is communicated with it, the oil cylinder of described hydraulic system places frame top, oil cylinder piston is connected with pressure head, guide rail on described pressure head both sides and the framework pillar inboard is slidingly connected, the frame of corresponding below with pressure head is provided with the cavity type worktable, the cylindrical of described worktable cooperates with bore in the tested butterfly valve, and the cavity of worktable is connected with water pot by water pipe and stop valve.
On the described stop valve water pressure gauge is installed, on the hydraulic system pipeline oil pressure gauge is housed.
Described frame side wall is equipped with the handle of control oil cylinder work.
Beneficial effect: because testing table is simple to operate, it is accurate to detect data, the butterfly valve of producing can be pursued the platform check, improve the ex factory pass rate of butterfly valve greatly.
