Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in figure 1, a kind of Valve pressure test device, using frame 1 as frame structure, the frame 1 includes base 1.1 and set
In the first support 1.2 and second support 1.3 of base 1.1.Movable valve bracket 6 is provided with the base 1.1 of frame 1, should
Movable valve bracket 6 can carry out the adjustment of size and location according to the different model of experiment valve 7.First support 1.2 with
Guide rail 2 is connected between second support 1.3, slide 3 is installed on the guide rail 2, slide 3 moves along guide rail 2, the slide 3 and
The drive device 4 of slide 3 is provided between two supports 1.3.First support 1.2 and slide 3 are respectively arranged with valve and clamp pressure testing
Device 5, the two valves clamp pressure testing device 5 and are oppositely arranged, in aspectant pattern.
As shown in Fig. 2 the valve, which clamps pressure testing device 5, includes cylinder body 5.1, piston 5.2 and PRESSURE TESTING BLIND FLANGE 5.3；Cylinder body
5.1 are provided with test(ing) medium import 5.4, and PRESSURE TESTING BLIND FLANGE 5.3 is provided with test(ing) medium outlet 5.5, and piston 5.2 is provided with connection examination
Test medium entrance 5.4 and the passage of test(ing) medium outlet 5.5.One in wherein two cylinder bodies 5.1 is fixedly connected on first support
On 1.2, another is fixedly connected on slide 3.Piston 5.2 is installed in cylinder body 5.1, is installed between piston 5.2 and cylinder body 5.1
Sealing ring 5.6 seals, and sealing ring type can select O-ring seal or V-shaped seal ring, and piston 5.2 pastes with the end face of cylinder body 5.1
Counter bore structure is provided with conjunction, counterbore can be located on piston 5.2 and can also be located on cylinder body 5.1, it is therefore an objective to be tested during pressure testing
Medium can quickly be filled with counterbore and then release piston 5.2.PRESSURE TESTING BLIND FLANGE 5.3 is fixed with piston 5.2 using bolt 5.9 to be connected
Connect, sealing ring 5.7 is installed between PRESSURE TESTING BLIND FLANGE 5.3 and the binding face of piston 5.2 and sealed, sealing ring 5.7 also can be replaced into sealing gasket
Sealing, ensure that test(ing) medium will not be revealed between PRESSURE TESTING BLIND FLANGE 5.3 and the binding face of piston 5.2, PRESSURE TESTING BLIND FLANGE 5.3 blocks pet valve
The position of 7 valve ports of door is provided with O type ring recess, mounting O-shaped sealing ring 5.8 to realize the reliable sealing to testing the valve port of valve 7,
The center of bolt 5.9 is provided with axial pass-through holes, matches somebody with somebody when the bolt 5.9 with the screwed hole on piston 5.2 as passage and merges
When PRESSURE TESTING BLIND FLANGE 5.3 is fixedly attached on piston 5.2, the axial pass-through holes on bolt 5.9 cause bolt 5.9 not block work
Passage on plug 5.2, makes test(ing) medium smoothly discharge.
Operation principle is as follows：
Before pressure testing, corresponding PRESSURE TESTING BLIND FLANGE 5.3, O-ring seal 5.8 and adjustment are changed according to the model of experiment valve 7 and moved
Dynamic formula valve bracket 6, experiment valve 7 is put just on movable valve bracket 6 after completing above-mentioned work, then manipulates slide 3
Drive device 4 causes the value pressure test clamping device on slide 3 to be moved to the value pressure test clamping device on opposite, and then clamps examination
Valve 7 is tested, pre-sealed, the pre-sealed pressure very little is realized to the valve port for testing valve 7, as long as experiment valve 7 can be clamped i.e.
Can.
During pressure testing, test(ing) medium is passed through from test(ing) medium import 5.4, then is filled with cylinder body 5.1 and the binding face of piston 5.2
Between counterbore space in, it is assumed that counterbore radius r0, the pressure of test(ing) medium is p0, the channel radius of piston 5.2 is relative to heavy
Pore radius is ignored, then the instantaneous pressure that now piston 5.2 is given by test(ing) medium isDue to the pressure
Power is much larger than the pre-sealed pressure that piston 5.2 is subject to, therefore piston 5.2 can be pushed open rapidly；Test(ing) medium again can be via work simultaneously
Passage on plug 5.2 is filled with experiment valve 7 by test(ing) medium outlet 5.5, and the test(ing) medium tested in valve 7 reaches steady
After determining state, it is assumed that now the radius of piston 5.2 is r1, the pressure of test(ing) medium is p1, the radius r of O-ring seal 5.82, piston
5.2 channel radius are ignored relative to the radius of piston 5.2, then now piston 5.2 is pressurized close to test(ing) medium inlet side
Power F1=p1·π·r1 2, and piston 5.2 is close to the experiment side pressure of valve 7ThereforeTwo pressure are proportional, i.e. the pressure p when test(ing) medium1When increase or reduction, piston 5.2 is acted on
On power F2Also increase or reduce, because of F1With F2It is directly proportional, therefore F1Also increase or reduction on year-on-year basis, it is not necessary at the very start to experiment
Valve 7 provides the clamping force of maximum, it is not easy to the valve port for testing valve 7 caused to damage, and because the radius r of piston 5.21It is more than
The radius r of O-ring seal 5.82Certain value, therefore the present apparatus can provide reliable clamping force and sealing effectiveness.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
