Abstract
The utility model discloses a balanced pneumatic adjusting device's in area voltage regulator, solve existing gas pressure regulator use inconvenient, unsafe problem. Upward membrane lid (9) and lower membrane lid (10) link firmly, form the executor die cavity, there are tray (8) and diaphragm (5) that are connected from top to bottom between the membrane lid, pull rod (7) are located the diaphragm, the tray axle center is rather than the connection, the diaphragm marks off membrane chamber and lower membrane chamber, the pull rod is connected with the one end of lever (6) of last membrane intracavity, the other end and the upper end of valve rod (4) of lever are connected, the supporting of lever is located the membrane lid, the lower extreme of valve rod is connected with valve clack (3) of valve body (1), valve clack and disk seat cooperation, membrane lid (10) is connected with end cover (11) down, there are atmospheric pressure interface (12) on the end cover.
Description
technical field:
The utility model is relevant with pressure governor, and the final controlling element in especially exigent with safety guarantee gas pressure regulator, governor is relevant.
background technique:
At present, in existing gas pressure regulator, governor, final controlling element is modal a kind of controlling device in direct acting type pressure governor, pressure above adjusting actuator interior diaphragm, and valve rod drives flap, controls valve port and opens and closes size, reach the object controlling flow.Compressing pressure adjusting spring by regulating pressure regulating screw to exert pressure to diaphragm, controlling moving up and down of valve rod, different outlet pressure needs the pressure adjusting spring changing different size model to test, and changes spring procedure complexity; Repeatedly assemble according to one-tenth, man-hour is wasted.The problems such as the phenomenons such as getting rusty easily appears in pressure adjusting spring in long-term using process, be oxidized, elastic force decay, discontinuity, cause pressure governor regulation precision to reduce, the inaccurate and thrashing of pressure regulation.User in use easily occurs that pressure raises suddenly or the uncertain phenomenon such as reduction suddenly, causes natural gas motorcar hidden danger, the accident such as serious caused fire, blast.
model utility content:
The purpose of this utility model is to provide a kind of uniform force, stablizes, the gas pressure regulator, governor of the band balance pneumatic regulation unit of use safety, life-span length.
The utility model is achieved in that
Upper membrane cover 9 and lower membrane cover 10 are connected, form final controlling element die cavity, the pallet 8 and diaphragm 5 that are connected is had between upper and lower membrane cover, pull bar 7 is positioned at diaphragm 5, pallet 8 axle center is connected with it, diaphragm marks off film chamber and bottom film chamber, pull bar is connected with one end of the lever 6 in upper film chamber, the other end of lever 6 is connected with the upper end of valve rod 4, the supporting of lever 6 is positioned at membrane cover 9, the lower end of valve rod 4 is connected with the flap 3 of valve body 1, flap 3 coordinates with valve seat 2, lower membrane cover 10 is connected with end cap 11, adjustable pressure enters in lower mode cavity by the air pressure interface 12 on end cap 11, adjust different atmospheric pressure sizes, evenly exert pressure to diaphragm 5 and pallet 8, steady pushing drawing rod 7 moves left and right, pull bar 7 passes through leverage, control valve rod 4 and flap 3 move up and down, control valve seat 2 openings of sizes, reach the effect of pressure governor pressure regulation.
The utility model has the following advantages:
One. adjustable pressure substitutes traditional pressure regulating screw, pressure adjusting spring, once assembles, and then adjusts adjustable pressure size, can reach pressure regulation effect, eliminates loaded down with trivial details membrane cover dismounting operation, saving of work and time.
Two. adjustable pressure to membrane surface uniform force, stable, when exporting pressure and breathing heavily shake, can the action of autobalance diaphragm, ensure pressure governor precision of voltage regulation safety, reliably.
Three. gas instead traditional metal materials, burning never again, get rusty, the phenomenon such as elastic force decay occurs, longer service life.
Four. debugging pressure governor simple and fast more, once assemble, then adjustable pressure carries out setting.
accompanying drawing illustrates:
Fig. 1 is structural drawing of the present utility model
embodiment:
The utility model is a kind of pressure governor balancing pneumatic regulation unit.Adjustable pressure directly substitutes traditional pressure regulating screw and pressure adjusting spring, the pressure size of regulating and controlling air pressure, applies different pressures to diaphragm, diaphragm applied force evenly, stable, balance and eliminate the diaphragm caused because outlet end air-flow is unstable and breathe heavily shake phenomenon, reach the effect of balance diaphragm.Upper membrane cover 9 and lower membrane cover 10 are connected, form final controlling element die cavity, the pallet 8 and diaphragm 5 that are connected is had between upper and lower membrane cover, pull bar 7 is positioned at diaphragm 5, pallet 8 axle center is connected with it, diaphragm marks off film chamber and bottom film chamber, pull bar is connected with one end of the lever 6 in upper film chamber, the other end of lever 6 is connected with the upper end of valve rod 4, the supporting of lever 6 is positioned at membrane cover 9, the lower end of valve rod 4 is connected with the flap 3 of valve body 1, flap 3 coordinates with valve seat 2, lower membrane cover 10 is connected with end cap 11, adjustable pressure enters in lower mode cavity by the air pressure interface 12 on end cap 11, adjust different atmospheric pressure sizes, evenly exert pressure to diaphragm 5 and pallet 8, steady pushing drawing rod 7 moves left and right, pull bar 7 passes through leverage, control valve rod 4 and flap 3 move up and down, control valve seat 2 openings of sizes, reach the effect of pressure governor pressure regulation.
