Abstract
The present invention relates to a kind of valve complete machine overpressure resistance detecting device, when carrying out valve complete machine resistance test, first valve body is placed between fastening screw and pressure difference flange, screw rod movement make fastening screw end face and pressure difference flange simultaneously with valve body or so flange contact, then water filling and pressurizeed in the blind hole of side pressure difference flange to the right, because the cross section of blind hole in pressure difference flange is more than valve body end runner mouth cross section, therefore produce pressure differential and promote the sealing flange of volume first inside pressure difference flange to hold out against valve body sealing surface, then pressurize carries out valve body voltage-withstand test；The present invention using pressure difference clamp valve body carry out voltage-withstand test, more traditional manual operation press from both sides steps up to compare, it is appropriate, controllable to the thrust of valve body, be not affected by human factors, inside test product without deformation, valve performance can be ensured.
Description
Technical field
The present invention relates to valve technology field, more particularly, to a kind of valve complete machine overpressure resistance detecting device.
Background technology
When carrying out the resistance test of valve complete machine, traditional detection mode is to use manual operation pinch valve, even if
Pressed from both sides with machinery respectively at the air inlet of pinch valve and at gas outlet, manually-operated randomness is larger, the pressure of machinery folder
It is too high, easily cause the deformation of valve body and valve inner part, influence the performance of valve.
The content of the invention
The technical problem to be solved in the present invention is：Manual operation pinch valve is used in the prior art in order to overcome, arbitrarily
Property it is larger, machinery folder pressure it is too high, easily cause the deformation of valve body and valve inner part, influence the performance of valve
The problem of, there is provided a kind of valve complete machine overpressure resistance detecting device.
The technical solution adopted for the present invention to solve the technical problems is：A kind of valve complete machine overpressure resistance detecting device, including：
Base, screw thread is provided with fastening screw on the base, and pressure difference flange, the pressure difference flange bag are installed with the base
Fixed seat is included, blind hole is offered in the fixed seat, the first sealing flange, the horizontal stroke of the blind hole are slidably fitted with the blind hole
Section radius are more than the cross sectional radius of valve flowing channel, offer inlet opening in the fixed seat, the inlet opening with it is described blind
Hole is connected.
During valve complete machine resistance test, first valve body is placed between fastening screw and pressure difference flange, screw rod movement makes to hold out against
Screw rod end face and pressure difference flange with valve body or so flange contact, then water filling and add to the right in the blind hole of side pressure difference flange simultaneously
Pressure, because the cross section of blind hole in pressure difference flange is more than valve body end runner mouth cross section, therefore produces pressure differential and promote in pressure difference flange
The sealing flange of portion's volume first holds out against valve body sealing surface, and then pressurize carries out valve body voltage-withstand test.
Described fastening screw one end is installed with the second sealing flange, the runner mouth using the second sealing flange to valve body
Sealed, there is preferable sealing property.
Sealing ring is installed between first sealing flange and the blind hole, is that the water inside blind hole will not be let out
Dew, can ensure the pressure inside blind hole.
In order that between the runner mouth of the sealing surface and valve body of the first sealing flange and second sealing flange realize compared with
Rubber ring is respectively and fixedly provided with the sealing surface of good sealing, first sealing flange and second sealing flange, it is some described
Rubber ring is coaxially disposed.
The beneficial effects of the invention are as follows:The valve complete machine overpressure resistance detecting device of the present invention, carrying out the pressure-resistant inspection of valve complete machine
During survey, first valve body is placed between fastening screw and pressure difference flange, screw rod movement makes fastening screw end face and pressure difference flange simultaneously
With valve body or so flange contact, then water filling and pressurizeed in the blind hole of side pressure difference flange to the right, because of the horizontal stroke of blind hole in pressure difference flange
Section is more than valve body end runner mouth cross section, therefore produces pressure differential and promote the sealing flange of volume first inside pressure difference flange to hold out against valve body
Sealing surface, then pressurize carry out valve body voltage-withstand test；The present invention clamps valve body using pressure difference and carries out voltage-withstand test, more traditional people
Work operation folder steps up to compare, appropriate, controllable to the thrust of valve body, be not affected by human factors, inside test product without deformation,
Valve performance can be ensured.

Embodiment
Presently in connection with accompanying drawing, the present invention will be further described in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of valve complete machine overpressure resistance detecting device as depicted in figs. 1 and 2, including：Base 1, screw thread peace on the base 1
Equipped with fastening screw 2, described one end of fastening screw 2 is installed with the second sealing flange 8, and pressure is installed with the base
Poor flange 3, the pressure difference flange 3 includes fixed seat 4, blind hole 5 is offered in the fixed seat 4, as shown in Figure 3 and Figure 4, described
The first sealing flange 6 is slidably fitted with blind hole 5, sealing is installed between first sealing flange 6 and the blind hole 5
Ring 9, the cross sectional radius of the blind hole 5 are more than the cross sectional radius of valve flowing channel, inlet opening 7 are offered in the fixed seat 4,
The inlet opening 7 is connected with the blind hole 5.
It is in order that real between the runner mouth of the sealing surface and valve body 11 of the first sealing flange 6 and second sealing flange 8
Rubber ring 10 is respectively and fixedly provided with the sealing surface of now preferably sealing, first sealing flange 6 and second sealing flange 8,
Some rubber rings 10 are coaxially disposed.
During valve complete machine resistance test, as shown in figure 5, first valve body 11 is placed between fastening screw 2 and pressure difference flange 3,
Screw rod movement make the end face of fastening screw 2 and pressure difference flange 3 simultaneously with the flange contact of valve body 11 or so, then side pressure difference flange to the right
