Embodiment Construction

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] The invention proposes a low pressure maintenance valve with a manual pressure relief function, which realizes the low pressure maintenance function during normal operation, and at the same time can manually release pressure and discharge oil during maintenance on the ground. The sealing method of the square sealing ring and the blank holder is simple in structure and process and has good sealing performance. Through the selection of different seals and reliable connection, the service life and pressure-holding characteristics of the low-pressure maintenance valve during use are guaranteed.

[0025] Low pressure maintenance valve structure with manual pressure relief function such as figure 1 shown. Including valve core 1, square sealing ring 2, blank holder 3, valve seat 4, valve body 5, maintenance valve spring 6, valve seat end 7, spring seat 8, loc...

Abstract

The invention relates to a low pressure maintenance valve with manual pressure relief function, comprising a valve core 1, a square sealing ring 2, a blank holder 3, a valve seat 4, a valve body 5, a maintenance valve spring 6, a valve seat end 7, a spring Seat 8, lock washer 9, nut 10, pin shaft 11, manual pressure relief valve core 12, knurled handwheel 13, pin shaft spring 14, valve body protection ring 15, valve body sealing ring 16, pin shaft sealing ring 17. Pin shaft protection ring 18, connecting pin 19, valve seat protection ring 20, valve seat sealing ring 21. The low pressure maintenance valve proposed by the invention realizes the low pressure maintenance function of the pressure accumulator during normal operation, and at the same time, it can manually release the pressure and discharge oil during the maintenance on the ground. The sealing method of the square sealing ring and the blank holder is adopted, which has good sealing performance and simple process. Through the selection of different seals and reliable connection, the service life and pressure-holding characteristics of the low-pressure maintenance valve during use are guaranteed.
