Problems solved by technology

For these high-pressure ball valves, if they are replaced frequently, in addition to being expensive and costly, during maintenance operations, since the pipelines of the gas dispenser are all hard-connected (some structures are still welded), the replacement is quite complicated.
To solve the problem of short service life of high-pressure ball valves, it is necessary to conduct quality comparison tests on existing products, select high-quality, cheap and high-quality product brands, and strictly control the quality of incoming inspections.

Embodiment 1

[0024] Such as figure 1 As shown, the natural gas high-pressure ball valve life test device includes a fixed frame 1, a drive motor 2, a counter 3, a transmission mechanism 4 and a clamp mechanism 6 for clamping the high-pressure ball valve 5, and the clamp mechanism 6 is installed on the fixed frame 1. One end, the drive motor 2 is installed on the other end of the fixed frame 1, the counter 3 is installed on one end of the power output shaft 21 of the drive motor 2, and the other end of the power output shaft 21 of the drive motor 2 passes through the transmission mechanism 4 Connect with high pressure ball valve 5. The structure is simple, and the counter 3 can accurately record the number of rotations of the power output shaft 21, thus ensuring the accuracy of the life test results.

[0025] The fixing frame 1 is in an overturned "L" shape. Such as figure 1 , the fixing frame 1 is plate-shaped, and this structure has good stability to ensure that the test can be carried...

Embodiment 2

[0030] This natural gas high-pressure ball valve life test device is the same as embodiment 1 except the following technical features: as figure 2 As shown, the transmission mechanism 4 includes an eccentric wheel 44, a fourth connecting rod 45 and a fifth connecting rod 46, the eccentric wheel 44 is installed on the other end of the power output shaft 21 of the drive motor 2, and the eccentric wheel 44 One end is connected to one end of the fourth connecting rod 45 , the other end of the fourth connecting rod 45 is connected to one end of the fifth connecting rod 46 , and the other end of the fifth connecting rod 46 is connected to the high pressure ball valve 5 . This implementation adopts the transmission mechanism 4 with a structure different from that of Embodiment 1, which can also ensure the effectiveness and stability of the transmission.

Abstract

The invention discloses a natural gas high-pressure ball valve life test apparatus. The apparatus comprises a fixation frame, a driving motor, a counter, a transmission mechanism and a clamp mechanism for clamping a high-pressure ball valve, wherein the clamp mechanism is installed at one end of the fixation frame, the driving motor is installed at the other end of the fixation frame, the counter is installed at one end of the power output shaft of the driving motor, and the other end of the power output shaft of the driving motor is connected with the high-pressure ball valve through the transmission mechanism. The apparatus provided by the invention enables the high-pressure ball valve to work through the driving motor and performs recording through the counter so as to accurately reflect the service life of the high-pressure ball valve.

Description

technical field [0001] The invention relates to a test device, in particular to a life test device for a natural gas high-pressure ball valve. Background technique [0002] With the continuous enhancement of people's awareness of green environmental protection, natural gas, a green and environmentally friendly fuel, is also being vigorously promoted in my country. Natural gas dispensers are an indispensable terminal settlement in the process of natural gas market transactions. equipment. After market research and field tests, it is found that the failure rate and maintenance rate of the gas dispensers currently in use in the market are relatively high, mainly reflected in the quality of parts. Such as: the high pressure ball valve of the air filling gun has a short service life, low reliability and so on. [0003] In view of the current use of gas dispensers in the market, the gun valve and high pressure ball valve of natural gas gas dispensers have been listed as vulnerabl...
