Pressure governor can adopt existing indirect acting type fuel gas pressure governor, formed by valve body assembly, pilot valve, indicator assembly etc., pilot valve is the individual components being combined by pressure transducer and pilot valve valve body assembly, only needs to change pressure transducer and just can significantly change outlet pressure.Downstream pressure is fed to the cavity of resorption of pilot valve by signal tube, make pilot valve diaphragm under the effect of downstream pressure, overcome the active force of bullet, drive pilot valve taper valve to move up by transmitting part, the aperture of pilot valve valve port and pilot valve flap is reduced, the pressure that is sent to pressure governor bottom film chamber reduces, main valve clack reduces with the aperture of primary valve under the drive of valve rod, reaches step-down and effect.
In the time that the gas consumption in pressure governor downstream increases, outlet pressure has a declining tendency.Now, the pressure drop of main valve cavity of resorption, moves down at the effect flap of spring, and just the aperture of flap and valve port strengthens, and increases by the gas flow of valve port from face, maintains the constant of downstream pressure.In the time that the gas consumption in pressure governor downstream reduces, its effect is contrary with said process, until pressure governor cuts out.
Install and use and safeguard:
Install: (1) checks whether gas transmission and distribution line pressure conforms to the applicable pressure range shown in pressure governor nameplate.
(2) check that whether the airflow arrows on pressure governor is consistent with the air-flow that pipeline is installed.
(3) at pressure governor front end, filter should be installed, safe bulk storage valve is installed in rear end, to ensure safe use gas.
(4) can employing level install.
(5) suggestion pressure governor outer pipe flow restriction is at 20m/s, and downstream line latus rectum should be greater than the outlet caliber of pressure governor if desired.
The use of pressure governor: (1) unscrews adjusting bolt; (2) slowly open the inlet valve before pressure governor; (3) by the adjusting bolt on slow with one's hands slow turn pilot valve, make outlet pressure reach setting value; (regulate clockwise, outlet pressure raises; Inhour regulates, and outlet pressure reduces.) pilot valve is provided with damper, pressure governor in the time of operation, as outlet pressure has now picture of surge, capable of regulating damping screw, damping adjusting screw is the unlatching sensitivity that improves pressure governor clockwise; Inhour is adjusted to reduction.If the shut-in time of pressure governor will lag behind when the unlatching sensitivity of pressure governor is too high, and outlet pressure superelevation while easily causing instantaneous closing.(4) slowly open the outlet valve of pressure governor rear end, until steady air current; (5) the inlet/outlet valve of pressure governor front and back ends is all opened.
The maintenance of pressure governor: (1) checks that with gas alarm instrument (or soap lye) pressure governor has or not external leakage.(2) closing pressure of inspection pressure governor: slowly closing pressure governor outlet end valve, detects mouth at pressure governor outlet end and connects pressure meter, and open switch.After 1 minute, record numerical value, check whether in normal range (NR).In the normal situation of pressure governor closing pressure, need not overhaul pressure governor.(3) pressure governor outside is cleaned.(4) clean pressure governor inside: in the time containing heavier dirt in gas medium, should regularly keep in repair clean to pressure governor inside.Swelling or the aging rubber parts of commute as: flap, 0 shape circle etc. should regularly check every year, to ensure safe way and normal use.(5) before maintenance, should, first by the inlet/outlet valve closing before and after pressure governor, release air pressure; Care should be used to when refitting, in order to avoid damage the parts such as valve port; After assembling, should check that can each movable part flexible motion; After helpdesk installs, the setting after keeping in repair by pressure governor ventilation operation method, and check that with soap lye all connection sealings position has or not leakage.
Downstream pressure is fed to the cavity of resorption of pilot valve by signal tube, make pilot valve diaphragm under the effect of downstream pressure, overcome the active force of bullet, drive pilot valve taper valve to move up by transmitting part, the aperture of pilot valve valve port and pilot valve flap is reduced, the pressure that is sent to pressure governor bottom film chamber reduces, main valve clack reduces with the aperture of primary valve under the drive of valve rod, reaches step-down and effect.In the time that the gas consumption in pressure governor downstream increases, outlet pressure has a declining tendency.Now, the pressure drop of main valve cavity of resorption, moves down at the effect flap of spring, and just the aperture of flap and valve port strengthens, and increases by the gas flow of valve port from face, maintains the constant of downstream pressure.In the time that the gas consumption in pressure governor downstream reduces, its effect is contrary with said process, until pressure governor cuts out.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to these embodiments' multiple amendment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
