The solenoid valve of described LPG globe valve durability test bench is provided with sound suppressor.
Be provided with tensimeter between the reduction valve of described LPG globe valve durability test bench and the solenoid valve.
Described LPG globe valve durability test bench adopts touch-sensitive display that parameter is set.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art has following advantage and good effect:
The present invention writes down the relation of pressure and cycle index automatically by control system and pressure transducer, and according to predefined pressure---the time relationship family curve is drawn corresponding top hole pressure and time relation curve automatically, has excellent sealing performance, and have degassing function, can discharge the air that gas tank is inner and tested valve is interior.
The present invention sets each parameter by touch-screen, and both pictures and texts are excellent makes the user have brand-new operation feeling; Because adopt servomotor, testing table can be set test frequency and number of times; Adopt computing machine to count automatically, can know the number of times that test is finished easily; This testing table is applicable to hand stop valve and solenoid valve, and implementation is flexible.
Description of drawings
Fig. 1 is a systematic schematic diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiments of the present invention relate to a kind of LPG globe valve durability test bench, and this testing table is designed at basic demand, test method and the key points for operation of the test of LPG globe valve durability specially according to national standard " GB18299-2001 ".It comprises serviceability test device and control system, and described control system is the PLC computer control system, is used to control the operation of serviceability test device, and detects the state of tested valve; Described serviceability test device comprises pressurized air input end, gas tank and servomotor; Described pressurized air input end comprises filtrator, reduction valve and the solenoid valve that links to each other successively, wherein, sound suppressor is housed to reduce noise on the solenoid valve; Described gas tank one end links to each other with described solenoid valve, and the other end links to each other with tested valve; Described gas tank is provided with pressure transducer, is used to test the preceding pressure of tested valve valve; Described tested valve links to each other with described servomotor, utilizes servomotor to drive the valve opening and closing.Wherein, servomotor links to each other with described tested valve by rotating flexible axle, makes this testing table be applicable to hand stop valve and solenoid valve, and implementation is quite flexible.What deserves to be mentioned is that this testing table is provided with parameter by the mode of touch-screen, both pictures and texts are excellent makes the user have brand-new operation feeling.Between solenoid valve and reduction valve, tensimeter can also be set in the pressurized air input end of this testing table, be used to observe the pressure of input air.Fig. 1 is a systematic schematic diagram of the present invention, and its concrete test procedure is as follows:
1) at first the LPG stop valve is installed on the LPG simulation bottle (being gas tank);
2) the rotation flexible axle that will be connected with servomotor is connected on the stop valve;
3) connect each tracheae and gas-tpe fitting, and guarantee to connect;
4) line of connecting with the mains, and set test frequency and cycle index by touch-screen, test frequency can be made as 1-10 time/min, and cycle index can be set to 6000 times;
5) press the button of starting working;
6) solenoid valve gets, the pressurized air input end is inflated to set pressure to the simulation bottle, start servomotor then, drive and rotate the flexible axle rotation, rotate thereby drive the LPG stop valve, make the LPG stop valve be in standard-sized sheet or full close position, wherein, the air pressure of pressurized air input end input is 8-10bar, and the air of input is a normal temperature, its consumption is 1000-3000LN/min, and pressure controling precision is at ± 0.5%FS;
7) the PLC computer control system detects the preceding force value of stop valve simultaneously, and shows with judgment device whether be in normal operating conditions in real time;
8) after the PLC computer control system detects electricly that time is up and sets cycle index, stop automatically.
Be not difficult to find, the present invention writes down the relation of pressure and cycle index automatically by control system and pressure transducer, and according to predefined pressure---the time relationship family curve is drawn corresponding top hole pressure and time relation curve automatically, has excellent sealing performance, and have degassing function, can discharge the air that gas tank is inner and tested valve is interior.
