Description
Technical field
The utility model relates to test mechanical technical field, is specifically related to a kind of hydrostatic tester articulated jib device.
Background technology
After valve has been produced, need to whether reach code requirement to valve and carry out multiple detection, it is exactly in order to test the water proofing property of valve that a hydraulic testing wherein is also called Shell test, and the external water proofing property of valve faucet.The main working medium of this test adopts the mode of high pressure to be punched into valve internal, simulates valve in the hyperbaric environment of using, then by valve medium whether leakage detects to judge whether test valve reaches requirement.Test(ing) medium is selected water, air or helium conventionally; When the pressure of needs tests is higher, preferably water detects, because water cumlative energy as little as possible; But at pressure during lower than 30 atmospheric pressure, with air and helium safe ready more.
When using air or helium to serve as medium to carry out the hydraulic testing, in order conveniently to check whether valve body leaks gas, conventionally need to be by whole being immersed in liquid cell of valve, once valve body leaks gas like this, just can be by the air-bubble observation of emerging out.But in liquid cell, put into assembling valve, and valve all need to be put into liquid cell by valve from the top of liquid cell when dismounting in liquid cell is taken out, then in liquid cell, assemble or dismantle, inconvenience very.When valve assembles or dismantles in liquid cell, the liquid in liquid need to be put totally simultaneously, and be needed to filling liquid in liquid cell in when test again, test process spended time is longer.
Summary of the invention
For above problem, the utility model provides a kind of convenience that test valve is enumerated, the hydrostatic tester articulated jib device that the installing/dismounting of valve can be operated in testing machine fluid box outside.
The utility model solves the technical scheme that its technical matters adopts: this hydrostatic tester articulated jib device is assemblied in the fluid box of hydrostatic test machine, comprise the stationary shaft being horizontally fixed in fluid box, symmetry is connected to the articulated jib at described stationary shaft two ends, the end of described articulated jib is joint flange, and the assembly flange that described joint flange sealing is assemblied in valve to be detected is with between high pressure gas flange; Described high pressure gas flange is connected with high-pressure air feed equipment by metal hose; Described articulated jib can be around described stationary shaft rotation, and described articulated jib is provided with level and vertical two fixed positions.
As excellent, revolve, on described articulated jib, be designed with abutment ring, in described fluid box, be designed with set collar, between described abutment ring and set collar, by the connecting link of different length, realize articulated jib fixing in level and vertical two positions.
As preferably, described high-pressure air feed equipment is assemblied in below in described fluid box, the horizontal fixed position that the upper surface of described high-pressure air feed equipment is articulated jib.
The beneficial effects of the utility model are: this hydrostatic tester articulated jib device is used on hydrostatic tester, valve to be detected is assemblied between two joint flanges on articulated jib, by high pressure gas flange and metal hose, valve internal is communicated with high-pressure gas circuit; Articulated jib is provided with level and vertical two fixed positions, when assembling or dismounting, articulated jib is adjusted to vertical position, now whole valve is all higher than fluid box, described like this valve dismounting assembling is all more convenient, in the time of need to testing, by articulated jib, valve is torqued into horizontal fixed position, if now fill with liquid in liquid cell, valve is all immersed in liquid.Then by high-pressure gas circuit, in valve, be filled with high pressure gas, by observation, have gas leakage just can judge the hydrostatic impermeability of valve.This device is directly valve to be screwed out to fluid box by rotation articulated jib in use, does not need the liquid in fluid box all to give out light like this when the dismounting of valve and assembling, has greatly saved detection time.

Fig. 2 be in Fig. 1 A-A to cross-sectional view.
Fig. 3 is the cross-sectional view of this hydrostatic tester articulated jib device side direction when handling.
Fig. 4 is that this hydrostatic tester articulated jib device is overlooked the structural representation of direction.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in Figure 1, Figure 2 with Fig. 4 in shown in embodiment, this hydrostatic tester articulated jib device, it is assemblied in the fluid box 1 of hydrostatic test machine, comprise the stationary shaft 2 being horizontally fixed in fluid box 1, symmetry is connected to the articulated jib 3 at described stationary shaft 2 two ends, the end of described articulated jib 3 is joint flange 31, and the assembly flange 41 that described joint flange 31 sealings are assemblied in valve 4 to be detected is with between high pressure gas flange 5; Described high pressure gas flange 5 is connected with high-pressure air feed equipment 7 by metal hose 6; Described articulated jib 3 can be around described stationary shaft 2 rotations, and described articulated jib 3 is provided with level and vertical two fixed positions.As shown in Figure 2 and Figure 4, described stationary shaft 2 fixes by symmetrical gusset and fluid box inwall, and described gusset forms triangle, stable connection in side surface direction and described fluid box arm as shown in Figure 2.Described flexible pipe 6 can arbitrarily bend, and when assembling, need to reserve sufficient length, facilitates the conversion requirement of 3 pairs of described valve 4 different azimuth of articulated jib.
This hydrostatic tester articulated jib device is used on hydrostatic tester, during detection, valve 4 need to be immersed in liquid.As shown in Figure 4, valve 4 to be detected is assemblied between two joint flanges 31 on articulated jib 3, by high pressure gas flange 5 and metal hose 6, valve 4 inside is communicated with high-pressure gas circuit; Articulated jib 3 is provided with level and vertical two fixed positions, it is specifically connected on described articulated jib 3 and is designed with abutment ring 32, in described fluid box 1, be designed with set collar 11, between described abutment ring 32 and set collar 11 by the connecting link of different length realize articulated jib 3 in level and vertical two positions separately fixing.As shown in Figure 2, be the structural representation of articulated jib 3 horizontal levels, now between abutment ring 32 and set collar 11, by stock 33, be connected, described valve 4 is immersed in liquid, can carry out high-pressure aerated checked operation to it.As shown in Figure 3, structural representation for articulated jib 3 vertical positions, now between abutment ring 32 and set collar 11, by quarter butt 34, be connected, articulated jib is adjusted to 2 whole these vertical positions that arrive when assembling or dismounting valve 4, now whole valve 4 is all higher than fluid box 1, the gravity of described valve 4 all concentrates on described articulated jib 3, all more convenient in the 4 dismounting assemblings of valve described in this position.
