In the present embodiment use process, using the preceding position first by adjusting adjusting seat 18 on shield 17, thus logical
The decrement of adjustment spring 20 is crossed to adjust the rated pressure between lower membrane cover 1 and big diaphragm 14, lower membrane cover 2 25 and diaphragm 27
Between rated pressure；It is carrying out in use, medium is entered in valve body 1 by inlet pipe 35, medium passes through outlet pipe 36 after valve body 1
Discharge, a part of medium are entered between lower membrane cover 1 and big diaphragm 14 by pipeline 2, and pressure is formed among this.Work as Jie
When the pressure of matter is lower than rated pressure, under spring force, promote big diaphragm 14 that push rod 10 is driven to move downward, push rod 10
The one end for driving upper lever 9 to connect with push rod 10 moves downward, and 9 other end of upper lever pushes upper valve rod 6 to move upwards, therefore on
Spacing between spool 7 and valve seat 3 increases, and the flow of medium flow direction outlet increases, to make to export pressure rise, stablizes in volume
Near constant-pressure.When the pressure of medium is greater than the rated pressure between lower membrane cover 1 and big diaphragm, pressure push big diaphragm 14 to
Upper protrusion, big diaphragm 14 drive push rod 10 to move upwards, and push rod 10 drives upper lever one end to be upturned, one end of upper lever 9
It is upturned, the other end is also just to sinking, and the other end is moved downward to the drive upper valve rod 6 that sinks, and upper valve rod 6 drives upper valve core 7
It moves downward, therefore the spacing between upper valve core 7 and valve seat 3 also just reduces therewith, traffic channel also just reduces to reduce therewith
Pressure medium stablizes outlet pressure near rated pressure；When system goes wrong or valve body 1 when something goes wrong causes
Pressure medium in pipe increases, even if being minimized traffic channel by pressure-regulating valve, but the pressure medium in outlet pipe 36
When still excessive, medium then passes through another pipeline in outlet pipe 36 and enters in lower membrane cover 2 25 and diaphragm 27, instantly membrane cover two
25 and diaphragm 27 in pressure when being greater than rated pressure between lower membrane cover 2 25 and diaphragm 27, pressure medium promotes diaphragm 27 downward
Protrusion, so that lower push-rod 28 be driven to move downward, lower push-rod 28 is moved downward, and drives one end of lower lever 32 connected to it
It moves downward therewith, lower 32 one end of lever moves downward, and the other end then rotates with it, therefore small valve-rod 31 is driven to transport to the left
Dynamic, small valve-rod 31 is connected between the import 33 and outlet 34 after moving to the left on small valve body 29, therefore the medium on inlet pipe 35
It is moved to by pipeline 2 at the import 33 of small valve body 29, is then transferred on valve deck 21 by the outlet 34 on small valve body 29
Import 33 at, and squeeze lower valve rod 23 inside and move upwards, lower valve rod 23 drives bottom spool 22 to move upwards, until lower valve
Core 22 blocks 3 bottom end of valve seat, makes do not carrying out medium transmission in valve body 1, after stopping, closing inlet pipe 35 to staff and carry out
Maintenance.
Beneficial effects of the present invention, by between push rod 10 and upper valve rod 6 be arranged upper lever 9, lower push-rod 28 with it is small
Lower lever 32 is set between valve rod 31, in order to required when reducing to sealing surface offer seal pressure to push big 14 He of diaphragm
The pressure of diaphragm 27, one end by will be close to fulcrum are connect with valve rod, and one end far from fulcrum is connect with push rod, and thick stick is utilized
Rod principle, pressure needed for reducing；Pass through the setting of pressure-regulating device 101 and disconnecting device 102, after medium superpressure, lower film
When pressure in lid 2 25 and diaphragm 27 is greater than the rated pressure between lower membrane cover 2 25 and diaphragm 27, under being promoted by pressure medium
Push rod 28 moves downward, and lower push-rod 28 moves downward, and one end of lower lever 32 connected to it is driven to move downward therewith, under
32 one end of lever moves downward, and the other end then rotates with it, therefore small valve-rod 31 is driven to move, small valve body after small valve-rod 31 moves
Connected between import 33 on 29 and outlet 34, the medium after connection on inlet pipe 35 by pipeline 2 move to small valve body 29 into
At mouth 33, then it is transferred at the import 33 on valve deck by the outlet 34 on small valve body 29, and squeeze lower valve rod inside
23 move upwards, and lower valve rod 23 drives bottom spool 22 to move upwards, until bottom spool 22 blocks 3 bottom end rear valve body of valve seat, 1 flow path
It directly cuts off, superpressure medium then will not continue to circulate after cutting, to avoid the safety accident in system below；Cutting
Device 102 makes regulating valve that can independently cut off traffic channel in the case where pressure medium is exceeded, after avoiding superpressure medium from flowing into
Continuous equipment, to cause safety accident.
Protection scope of the present invention is not limited to above embodiments and its transformation.Those skilled in that art are with the present embodiment
The conventional modification and replacement carried out based on content, belongs to protection category of the invention.
