Referring to Fig. 1, Fig. 2, Fig. 3, valve body structure is: form low-pressure chamber (6) by the bonnet that is threaded (2) above the secondary valve body (10); Secondary valve body (10) forms one-level valve body air chamber (11) below by the one-level valve body (12) that is threaded; Press-fit first diaphragm (28) at secondary valve body (10) and one-level valve body (12) junction plane and one cushion block seat (22) is installed at diaphragm (28) mider hole place, by nut (29) itself and diaphragm (28) are tightened up, cushion block seat (22) is provided with the inclined hole (23) of ventilation, be provided with middle pressing spring (20) in the cavity of the secondary valve body (10) above cushion block seat (22), one-level valve body air chamber (11) is communicated with middle plenum chamber (7) by inclined hole (23); With bonnet (2) surface of contact diaphragm (18) big cushion block (17) is installed from bottom to up in secondary valve body (10) upper end, big spring (4) and small cushion block (3), the bottom of regulating handgrip (1) withstands on the small cushion block (3), in one-level valve body (12) and secondary valve body (10) middle part cavity, little spring (34) (27) is housed from bottom to up successively, valve supporter (33), (35), valve (13) (5), valve seat (31), (36), one-level push rod (25), secondary push rod (19), valve seat (31), (36) be provided with the inclined hole (30) of ventilation, (32), one-level push rod (25) contacts with cushion block seat (22); Secondary push rod (19) contacts with diaphragm (18); Air input joint (24) is communicated with the plenum chamber (14) of one-level valve body (12); Low-pressure chamber (6) connects mouth (9) and is communicated with giving vent to anger.
The utility model is that a valve inner is divided into three air chambers, i.e. plenum chamber (14), one-level valve body air chamber (11) (middle plenum chamber) and secondary valve body air chamber (6) (low-pressure chamber).Narrate the utility model working principle below by example: when pressurized gas enter plenum chamber (14) by air input joint (24), high pressure gauge outfit (26) shows numerical value, because of when one-level valve body (12) and secondary valve body (10) are installed, middle pressing spring (20) is compressed and promotes cushion block seat (22), cushion block seat (22) bottom contact one-level push rod (25), drive valve (13), make valve (13) lift off a seat (31) form the gap, at this moment just plenum chamber (11) from valve (13) flows into by the inclined hole (30) on the valve seat (31) all around of pressurized gas, from plenum chamber (14) to the gas of plenum chamber (11) obtain suddenly because of volume increases expanding and cause gas pressure to descend, so just realized one-level decompression of the present utility model.The inclined hole (23) of medium pressure gas by cushion block seat (22) the formation medium pressure gas that links to each other with the air chamber (7) of secondary valve body (10).Handgrip (1) is regulated in rotation, by small cushion block (3) compression big spring (4), promote big cushion block (17) and diaphragm (18), simultaneously, contact secondary push rod (19), and open valve (5), make valve (5) lift off a seat (36) form the gap, at this moment, the gas of middle plenum chamber (7) is just gone up inclined hole (32) by valve seat (36) all around from valve (5) and is flowed into low rustic chamber (6).This gas obtains suddenly expanding because of volume increases and causes gas pressure to descend as a same reason.So just finished secondary decompression of the present utility model.The gas that connects mouth (9) output of giving vent to anger can be regulated gas pressure by regulating handgrip (1), to satisfy the needs of real work.
