Before gas pressure regulating station, be equipped with filter, filter housing is a hermetically sealed can being connected between gas inlet pipe and gas outlet pipe, in hermetically sealed can inside, filtering net cylinder is set, the lower port of filtering net cylinder is connected with gas outlet pipe by transverse tube, and periphery and the filter housing of transverse tube are tightly connected.In normal air feed process, combustion gas enters filter housing inside from air inlet pipe, through screen tube, then enters gas outlet pipe arrival user.Residual impurity in combustion gas is attracted on filtering net cylinder, and through operation for a long time, the residual impurity in combustion gas can stop up filtering net cylinder, has reduced supply gas pressure, can not ensure that voltage regulating station normally works.In prior art, maintenance filter cleaning filtering net cylinder has two kinds of methods, and the one, stop the supple of gas or steam and open filter housing, take out filtering net cylinder and clean; The 2nd, do not open filter housing, knock filter housing with "painted-face" character in opera, by the method for knocking, the combustion gas residual impurity of filtering net cylinder absorption is shaken, residual impurity is discharged from the sewage draining valve of filter housing bottom.The drawback of above-mentioned two kinds of methods is: the first method maintenance of stopping the supple of gas or steam, and time-consuming and cost is high, the upkeep operation time is long, and working strength is large, makes troubles to resident living, frequent dismounting flange gasket, equipment is fragile.The second knocks the method for vibrations, removes combustion gas residual impurity weak effect, can not meet service requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gas pressure regulating station filter cleaning, has the advantages that not disassemble the purging filtering net cylinder that filter housing can be clean fast.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of gas pressure regulating station filter cleaning, comprises the left appendix that is connected with filter housing left side wall, is positioned at the right appendix on filter housing right side and blowback is housed the branched pipe of sweeping valve; Described left appendix is provided with left valve, right appendix is provided with right valve, in described filter housing, be provided with filtering net cylinder, between the lower port of described filtering net cylinder and right appendix left port, be communicated with transverse tube, described transverse tube periphery and filter housing are tightly connected, and the lower port of described filter housing is provided with the blow-off pipe with blowoff valve; One end of described branched pipe is connected with the right appendix of right valve left end.
The further improvement that the utility model is done is: the other end of described branched pipe is connected with the left appendix of left valve left end.The other end of described branched pipe is connected with compressed air source.Also comprise left Pressure gauge and right Pressure gauge, described left Pressure gauge is arranged on the left appendix between left valve and filter housing, and described right Pressure gauge is arranged on the right appendix between right valve and filter housing.
The beneficial effect that adopts technique scheme to produce is: the utility model is in the time of the filter of maintenance gas pressure regulating station, needn't open filter housing, can utilize the combustion gas in gas pipeline, can also utilize compressed air or other sources of the gas, the filtering net cylinder of filter housing inside is carried out to blowback to be swept, the residual impurity of removing combustion gas, this apparatus structure is simple, convenient to use, it is clean that filtering net cylinder purges, can raise labour efficiency, reduce labor intensity, extension device service life.
