Abstract
A kind of non-return valve opening pressure proving installation, comprise air compressor machine, after air compressor machine, by pipeline, connect successively high pressure tank, variable valve, low pressure gasholder and tested valve, tensimeter and safety valve are installed, setting pressure sensor between low pressure gasholder and tested valve on high pressure tank and low pressure gasholder.The beneficial effects of the utility model are: by observing the numerical value of pressure transducer, can obtain the opening pressure of non-return valve, device is simple, and data are accurate; This proving installation is Open architecture, changes conveniently highly versatile.
Description
Technical field
The utility model relates to a kind of proving installation, particularly relates to a kind of device of testing non-return valve opening pressure size.
Background technology
The opening pressure of non-return valve regulation not in relevant criterion, can not measure these data in prior art yet, but one of opening pressure performance parameter that to be non-return valve important, to process system, safe operation has material impact.Opening pressure is mainly subject to the impact of the factors such as version, valve aperture, valve body generation type, inner structure, different its opening pressures of check valve structure are different, measure non-return valve opening pressure accurately, as the data input of research and development designs, to the optimal design of non-return valve, process modification and under different operating modes non-return valve select all significant.
Summary of the invention
In order to overcome the shortcoming that in prior art, non-return valve opening pressure cannot be definite, it is a kind of convenient, fast and can directly record the proving installation of non-return valve opening pressure that the utility model provides.
It is a kind of non-return valve opening pressure proving installation that the utility model solves the technical scheme that its technical matters adopts, comprise test macro, test macro comprises air compressor machine, after air compressor machine, by pipeline, connect successively high pressure tank, variable valve, low pressure gasholder and tested valve, tensimeter and safety valve are all installed, setting pressure sensor between low pressure gasholder and tested valve on high pressure tank and low pressure gasholder.
The beneficial effects of the utility model are:
1, by observing the numerical value of pressure transducer, can obtain the opening pressure of non-return valve, device is simple, and data are accurate;
2, this proving installation is Open architecture, changes conveniently highly versatile.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural map of the present embodiment;
In figure: 1. air compressor machine; 2. tensimeter A; 3. safety valve A; 4. high pressure tank; 5. variable valve; 6. tensimeter B; 7. safety valve B; 8. low pressure gasholder; 9. pressure transducer; 10. tested valve.
Embodiment
As shown in Figure 1, a kind of non-return valve opening pressure proving installation, comprise air compressor machine 1, after air compressor machine 1, by pipeline, connect successively high pressure tank 4, variable valve, low pressure gasholder 8 and tested valve 10, tensimeter A2 and safety valve A3 are installed on high pressure tank 4, tensimeter B6 and safety valve B7 are installed, setting pressure sensor 9 between low pressure gasholder 8 and tested valve 10 on low pressure gasholder 8.
Before test, variable valve 5, in closed condition, is opened air compressor machine 1, makes high pressure tank 4 be full of the pressurized air of set pressure.
During test, first open variable valve 5, make pressurized air enter low pressure gasholder 8, the aperture of accurate adjustment variable valve 5, guarantees that the slow balance of low pressure gasholder 8 pressure increases progressively, and observes the numerical value of pressure transducer 9, when numerical value no longer increases, when flap place has medium to leak, this value is the opening pressure of non-return valve.
Claims (1)
1. a non-return valve opening pressure proving installation, comprise test macro, it is characterized in that: described test macro comprises air compressor machine, after air compressor machine, by pipeline, connect successively high pressure tank, variable valve, low pressure gasholder and tested valve, tensimeter and safety valve are installed, setting pressure sensor between described low pressure gasholder and described tested valve on described high pressure tank and low pressure gasholder.
