Description
Technical field
The invention belongs to pipeline scrubbing component technology field, relate to a kind of dirt removing device, particularly a kind of Magnetic dirt separator.
Background technique
When utilizing steel pipe market liquid. often make pipeline inside retain irony residue when pipeline installation, or can iron oxides impurities be produced in long-term conveying flow liquid process. lodge in some position in pipeline gradually. the flow of conveying fluid can be had a strong impact on.Or the operation affecting the pipe fittings such as flowmeter, gate valve uses, and the liquid be transferred also can be made to be mixed with more mechanical admixture, the quality of impact conveying liquid.
In filtering fluid, the conventional method of residue has been public from known, such as: volume hole filter core, braided fabric, winded filtering core, paper and emblem pore membrane filter core etc., they have a common shortcoming, opening of sieve is fixing, mechanical admixture is embedded in filter opening and is difficult to backwash regeneration, generally can only single use. the especially more difficult recovery pre-existent pore degree when injection water contains micro-greasy dirt, cause filter element replacing frequent, consumption is very big.
As a kind of magnetic filtering valve [application number: 200420096170.6 that Chinese patent literature data openly proposes, Authorization Notice No.: CN 2728596Y], by valve gap, seal ring, connecting base, filter screen, water outlet, valve body, water intake, magnet body, protecting jacket, connecting bolt, the compositions such as oblique valve-rod body, the top of oblique valve-rod body is connected by screw thread and valve gap, valve gap there is connecting bolt, one or more magnet body is inlayed to be sealed in protecting jacket, protecting jacket is connected with connecting base by socket or screw thread, connecting base is connected with connecting bolt by screw thread again, metal screen is stuck in valve gap, in the circular groove of the surrounding of connecting bolt, seal ring is had between valve gap and oblique valve-rod body.But this magnetic filtering valve is when removing the impurity on magnet body, and need the protecting jacket of magnet body to be housed under valve body dismounting, therefore dismounting magnet body is comparatively inconvenient.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of Magnetic dirt separator can being convenient to be taken off by magnet piece.
Object of the present invention realizes by following technical proposal: a kind of Magnetic dirt separator, comprise the inner valve body for cavity, the sidepiece of described valve body is provided with feed-water end and waterexit end, also be provided with filter screen in the cavity of described valve body and described filter screen between described feed-water end and described waterexit end, it is characterized in that, the sidewall of described valve body is equipped with tubular sleeve pipe, the outer wall of described sleeve pipe is connected with described valve seal, the inner of described sleeve pipe is positioned at the cavity of described valve body, magnet piece is removably connected with in described sleeve pipe, the bottom of described valve body is provided with pollution discharge mechanism.
During use, liquid enters in the cavity of valve body from feed-water end, owing to being provided with filter screen in the cavity of valve body, therefore the impurity in liquid is filtered net and adsorbs rear and sink, because the sleeve pipe on the sidewall of valve body is provided with magnet piece, therefore, having ferromagnetic impurity is adsorbed on the outer wall of sleeve pipe, when after use a period of time, magnet piece in sleeve pipe can be taken out, the impurity be now attracted on the outer wall of sleeve pipe sinks under gravity, is then opened by pollution discharge mechanism, is excluded by the impurity in cavity.By arranging sleeve pipe, in sleeve pipe, being provided with magnet piece, making the installation and removal of magnet piece more for convenience.The inner of sleeve pipe is positioned at the cavity of valve body and its end is positioned at the axis place of the cavity of valve body, can have good suction-operated to the ferromagnetic impurity in cavity.Opened by the sewage draining exit of the bottom by valve body, impurity is got rid of clean, have and operate conveniently advantage.
