Detailed description of the invention
With reference to the accompanying drawings, in conjunction with the embodiments, to gas control shuttle valve of the present utility model, it is described in detail.
Embodiment one
1-Fig. 2 referring to the drawings, the gas control shuttle valve of the present embodiment, including shuttle valve body I1, shuttle valve body II2, spring 3, piston 4, clamp nut 8, seal spool pad 9, spool 10, go out end cap 11, shuttle valve body II2 is provided with air inlet a12 on sidewall platform, air inlet b13, shuttle valve body I1 is welded and fixed with shuttle valve body II2, shuttle valve body II2 is screwed with going out end cap 11, going out end cap 11 Internal back end and be threaded the spool 10 of connection, fixed spool sealing gasket 9 between spool 10 and clamp nut 8, piston 4 is arranged on out in the space between end cap 11 and shuttle valve body I1, a confined space is formed with seal spool pad 9.Air inlet a12, one end of air inlet b13 are connected with outside air-control device, and the confined space that the other end is formed with shuttle valve body II2 with piston 4 is connected.
Shuttle valve body I1, piston 4, go out the seal groove of end cap 11 in be respectively fixed with piston ring 5, O 6, Y-shaped ring 7, it is achieved Valve controlling seals with action.And 3 springs arranged between end cap are gone out at 4 pistons and 1 shuttle valve body I and 11.
Spring 3 is arranged on one end of shuttle valve body I1, for closed type gas control shuttle valve；Spring 3 is arranged on out one end of end cap 11, for open type gas control shuttle valve.
Compressed air is alternately entered control room supply by air inlet a12 and air inlet b13, promotes piston 4 to move reciprocatingly, thus realizes the open and close of shuttle valve.
When shuttle valve cuts out, after compressed air is entered control room by air inlet a12, forcing piston 4 end motion to the right and terminate at the seal spool pad 9 of spool 10, medium residence is at spool 10 left end, it is achieved shuttle valve cuts out.
