Detailed Description
The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1-6, the present invention can be used in the following manner:
first, a chair can be placed in front of the test stand 1, and the test stand can sit on the chair to work. Firstly, the second pedal 23 is stepped on, the second pedal 23 moves downwards and drives the second traction rope 22 to move downwards, the second pedal 23 enables the two sliding plates 13 to simultaneously slide back to back along the sliding rails 14 through the second traction rope 22, and the sealing plate 11 is far away from the placing frame 2. The ball valve 3 to be tested can then be placed on the placing frame 2.
Then the second footboard 23 is loosened to the right foot, the first footboard 21 is stepped on to the left foot, pull two slides 13 simultaneously and slide in opposite directions through first haulage rope 20, in the slip in-process, the sealing plate 15 that seals the board 11 and be close to ball valve 3 one side can contact ball valve 3 at first, at this moment continue to trample first footboard 21, pull slide 13 and the device section of thick bamboo 8 and continue to slide, at this moment seal the board 11 and can slide to the outside for the device section of thick bamboo 8, and then drive first trachea 10 and slide, first spring 17 is compressed gradually, the pressure between sealing board 11 and the ball valve 3 grow gradually, inboard sealing plate 15 is extrudeed deformation here gradually and is regarded as the inboard with the one side that is close to ball valve 3, the one side of keeping away from ball valve 3 is the outside. The first pedal 21 is further stepped down until the outer sealing sheet 15 abuts against the inner side of the device cylinder 8, and at this time, the inner sealing sheet 15 cooperates with the sealing plate 11 to complete the sealing of the ball valve 3. When the outer sealing sheet 15 is abutted to the device barrel 8, a worker can determine that sufficient pressure exists between the inner sealing sheet 15 and the ball valve 3 to seal the ball valve 3, and then the position of the first pedal 21 is kept without forcibly treading. And this kind tramples first footboard 21, just can easily seal the mode of ball valve 3 through first haulage rope 20, and the looks operation is simple swift, does not need a large amount of hand actions moreover, rationally allots the health, avoids hand local fatigue.
At this time, the ball valve 3 is in a closed state, the first air pump 5 and the second air pump 6 can be simultaneously opened, and the air pressure increase speed on the two sides of the ball valve 3 is different because the power of the first air pump 5 is greater than that of the second air pump 6. The two air pumps start to inflate the ball valve 3 through the first air pipe 10 and the second air pipe 12, and stop after a period of time. At this time, the airtightness of the ball valve 3 can be confirmed by observing the change in the air pressure values of the two dials 19, and if the air pressure on the high pressure side decreases at a rate exceeding a predetermined value and the air pressure on the low pressure side increases at a rate exceeding a predetermined value, the airtightness of the ball valve 3 is poor. If the air tightness does not exceed a predetermined value, the air tightness is good.
After the test is finished, the first pedal 21 is loosened by the left foot, the second pedal 23 is stepped by the right foot again, the two sealing devices 4 slide back to back, the ball valve 3 which is finished in the test is taken down, and another ball valve 3 to be tested is put on.
Embodiment two, when the second footboard 23 was trampled to the right foot, upwards pulled up the clamp plate 27 through third haulage rope 29, and second spring 28 contracts, and then will await measuring ball valve 3 and place on rack 2 to the valve rod of ball valve 3 lies in the opening forward, loosens second footboard 23, and then second spring 28 resets, and promotion clamp plate 27 fixes ball valve 3 on rack 2, places the unexpected perk of ball valve 3, makes things convenient for two closing device 4 to seal ball valve 3.
