The specific embodiment

Referring to Fig. 1, a kind of one way valve control hydraulic pressure height-adjustable supports, include upper bracket top cover 1, middle steel liner plate 10 in the structure, have the benzvalene form undersetting chassis 6 of injecting pipeline 4, at tetrafluoro sliding panel 2 that is provided with between bearing top cover 1 and the middle steel liner plate 10 and the pressure-bearing rubber tile 3 that between middle steel liner plate 10 and benzvalene form undersetting chassis 6, is provided with, also be provided with a circle lip protruding 7 on the bottom round edge of described pressure-bearing rubber tile 3.

On rubber tile 3 bottom faces, also be provided with one group of groove, be filled with boss 8 in the groove, boss 8 closely cooperates with groove, and is not less than the size of groove inner chamber, cooperates lip protruding 7 can further improve the sealing of the cavity of rubber tile 3 and undersetting chassis 6 compositions.

Injection pipeline 4 is provided with one way valve 5, above one way valve 5 is positioned at the exit of injection pipeline 4, solidify easily owing to gazing at agent in the process of gazing at agent in injection, one way valve 5 moved to from outer injection-tube crossing be positioned at the undersetting dish, can reduce and gaze at agent and solidify the injection pipeline 4 that causes and stop up.

Bottom in benzvalene form undersetting chassis 6 also be provided with inject that pipeline 4 outlet is communicated with gaze at agent guiding gutter 9, when gazing at the agent injection, to gaze at agent water conservancy diversion stream and completely gaze at agent guiding gutter 9, formation is evenly exerted pressure to rubber tile 3, and rubber tile 3 discontinuity cause when avoiding not gazing at the agent guiding gutter upper bracket top cover 1 tilts and gazes at problem such as agent seepage.
