Utility model content
In view of this, the utility model provides a kind of flange installing type valve leak amount detecting device, can realize pair
The leakage rate of flange installing type valve carries out quantitative detection, and without dismounting valve, convenient and efficient.
The flange installing type valve leak amount detecting device of the utility model, including：A pair of of flange end socket, goes out air inlet pipe
Tracheae, container and air source, peripheral equipment are flange installing type valve；
Wherein, a pair of of flange end socket is separately mounted to the both ends of flange installing type valve；The flange end socket is equipped with logical
Hole；The air inlet pipe and an air outlet pipe according to the detection of leakage rate flow to, respectively with the flange end socket at flange installing type valve both ends
On through-hole be tightly connected；The air inlet pipe connects air source, and the escape pipe is extend into the solution in container, in the container
Solution and the detection gas in air source are immiscible.
Further, further include plug-in quick coupling, air inlet pipe and an air outlet pipe by plug-in quick coupling with it is logical
Hole connects.
Further, it is deep to be dipped vertically into container 5~10mm under liquid level for the escape pipe.
Further, the outlet pipe outside diameter 6mm, wall thickness 1mm, pipe surface is smooth, no chamfering and burr.
Advantageous effect：
The utility model is directly introduced a gas into using flange end socket, air inlet pipe in flange installing type valve, then passes through system
The gas output of meter escape pipe obtains the leakage rate of flange installing type valve, can realize quantitative detection, and structure of the detecting device letter
It is single, it is convenient and efficient without dismounting valve, it can realize two-way leakage rate detection.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1- flanges installing type valve, 2- flanges end socket, 3- air inlet pipe, 4- escape pipes, 5- quick couplings, 6- containers,
7- air sources, 8- solution, 9- bubbles, 10- pressure gauges.
Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is described in detail.
The utility model provides a kind of flange installing type valve leak amount detecting device, as shown in Figure 1, for flange
Installing type valve 1 carries out leakage rate detection, including a pair of of flange end socket 2, air inlet pipe 3, escape pipe 4, container 6 and air source 7,
In, a pair of of flange end socket 2 is separately mounted to the both ends of flange installing type valve 1, one is respectively equipped on the pair of flange end socket 2
A through-hole；Air inlet pipe 3 and escape pipe 4 are flowed to according to the detection of leakage rate, are connect respectively with the through-hole on flange end socket 2；Air inlet
3/ escape pipe 4 of pipe and the junction of through-hole are equipped with sealing ring, prevent gas from leaking, can also be connected by plug-in quick coupling
It connects, i.e. 3/ escape pipe 4 of air inlet pipe is connected to by plug-in quick coupling on through-hole.The air inlet pipe 3 connects air source 7, it is described go out
Tracheae 4 is extend into the solution in container 6, and the solution in container 6 is generally water, or other are immiscible with detection gas
Solution.Detection gas in air source 7 pass through air inlet pipe 3, flange installing type valve 1 and escape pipe 4 successively, from container 6
It is come out in the form of bubble；Flange installing type valve 1 be can be obtained by counting the bubbles volume in the container 6 in a period of time to exist
The downward leakage rate of detection stream.
The utility model detection device is convenient and efficient when detecting, and flange end socket size can be made as needed, with
Detect the valve of different bores.The utility model is without dismounting flange installing type valve, and inverse detection if necessary,
Air inlet pipe and escape pipe need to only be exchanged, it is convenient and efficient.
For flange installing type pneumatic control valve, the utility model is additionally provided with two pressure gauges, is distinguished using pressure gauge 10
Detect the pressure at flange installing type valve both ends.The regulation of GB/T4213-2008 according to national standards, when permitting for pneumatic control valve
Perhaps pressure difference>When 350kPa, the gas pressure in air source is done by 350kPa, and gas valve opening operator signals are zero, and air to close valve is held
Row mechanism signal pressure is that input signal upper limit value increases 20kPa.Gas in air source is flowed to by regulation to be added in pneumatic operated valve, valve
It outlet can be directly with the measuring device of air or the open to atmosphere low head loss of connection outlet, when confirmation pneumatic operated valve and escape pipe are complete
Entirely simultaneously leakage rate can be measured after leakage rate is stablized full of medium.Wherein, 4 outer diameter 6mm of escape pipe, wall thickness 1mm, are dipped vertically into appearance
5~10mm is deep under liquid level in device 6, and pipe surface is smooth, no chamfering and burr, etc. after number of bubbles stablize, it is per minute by calculating
Number of bubbles obtains the leakage rate of flange installing type pneumatic operated valve.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection domain.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
