Abstract
The utility model discloses a kind of filter with pressure release dirt eliminating function, it filter screen comprising housing and be arranged on enclosure interior, housing is provided with entrance and exit, is provided with reinforcement boss at housing bottom; In the middle part of reinforcement boss, be vertically provided with tapped through hole, in tapped through hole, be bolted with plug; Plug first half sidewall is provided with gas pressure relief slot vertically.Advantage of the present utility model: by the screw-in of plug with screw out and can solve the problems such as filter blowdown, pressure release; Can know and judge the whether complete pressure release of equipment with pressure, thoroughly avoid the generation of the accidents such as petrol station is emptying, equipment stoppage in transit, unit chaser, improve equipment dependability, stopped potential safety hazard.
Description
Technical field:
The utility model relates to a kind of filter, relates in particular to a kind of filter with pressure release dirt eliminating function.
Background technology:
Current thermal power plant fan oil station filter all adopts switchover operation mode, and when transfer valve imprecision, the oil-feed simultaneously of bilateral filter interior also with elevated pressures, when maintainer dismantles, cannot judge whether filter internal pressure discharges completely; Taking filter oil pressure apart when there is oil pressure can abrupt release, uncontrollable, finally causes that petrol station is emptying, equipment is stopped transport, unit chaser, bring considerable risk can to the personal safety of maintainer simultaneously.
Utility model content:
The purpose of this utility model is to provide a kind of filter with pressure release dirt eliminating function.
The utility model is implemented by following technical scheme: a kind of filter with pressure release dirt eliminating function, it filter screen comprising housing and be arranged on described enclosure interior, is provided with entrance and exit on the housing, is provided with reinforcement boss at described housing bottom; In the middle part of described reinforcement boss, be vertically provided with tapped through hole, in described tapped through hole, be bolted with plug; Described plug first half sidewall is provided with gas pressure relief slot vertically.
Described housing and described reinforcement boss one-body molded.
Gasket seal is provided with between described plug end face and described reinforcement raised head face.
Advantage of the present utility model: by the screw-in of plug with screw out and can solve the problems such as filter blowdown, pressure release; Can know and judge the whether complete pressure release of equipment with pressure, thoroughly avoid the generation of the accidents such as petrol station is emptying, equipment stoppage in transit, unit chaser, improve equipment dependability, stopped potential safety hazard.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Housing 1, filter screen 2, entrance 3, outlet 4, reinforcement boss 5, tapped through hole 6, plug 7, gas pressure relief slot 8, gasket seal 9.
Detailed description of the invention: as depicted in figs. 1 and 2, a kind of filter with pressure release dirt eliminating function, it filter screen 2 comprising housing 1 and be arranged on housing 1 inside, housing 1 is provided with entrance 3 and outlet 4, be provided with bottom housing 1 and strengthen boss 5, housing 1 is one-body molded with reinforcement boss 5, strengthens boss 5 and can strengthen housing 1 bottom strength; In the middle part of reinforcement boss 5, be vertically provided with tapped through hole 6, in tapped through hole 6, be bolted with plug 7, between plug 7 end face and reinforcement boss 5 end face, be provided with gasket seal 9; Plug 7 first half sidewall is provided with gas pressure relief slot 8 vertically, and plug 7 need not screw out the pressure release and blowdown effect that can realize filter completely.
After petrol station transfer valve switches, plug 7 is slowly outwards screwed out until the gas pressure relief slot 8 on plug 7 exposes, observe the fuel-displaced situation of gas pressure relief slot 8, if have oil in gas pressure relief slot 8 all the time and discharge with pressure, prove that transfer valve is not tight, can not filter be dismantled, immediately plug 7 be screwed in tapped through hole 6, prevent petrol station from running oil; If gas pressure relief slot 8 stops fuel-displaced in short-term, prove that switch is tight, can filter service work be carried out.
