Abstract
The utility model discloses an air filter, in particular to an air filter with a one-way valve, wherein the one-way valve is installed on the filter comprising a copper-bead sintered filtering core and an aluminum cup sleeved outside the filtering core, so that the copper-bead sintered filtering core and the aluminum cup are respectively fixed with the one-way valve, thereby not only the filter is ensured to still normally work under the condition that the copper-bead sintered filtering core is blocked, but also workers are facilitated to clean the copper-bead sintered filtering core as soon as possible. The air filter is mainly applicable to the purification requirements of gas pipelines of industries, such as railway locomotives, metallurgy, mines, machinery and electron, instruments and meters, casting and forging, petrochemical industry, medicines and foods, hygiene and shipbuilding and the like.
Description
Technical field:
The utility model relates to a kind of filter, especially a kind of air filter that has check valve.
Background technology:
In pipeline was carried, filter was the requisite visual plant of a kind of raising fluid mass.The filter interior of filtering gas pipeline dust impurity has only been installed a filter at present, when long-term use, filter is easily stopped up by dust impurity, causes the filter outlet flow to reduce, even there is not a flow, have a strong impact on the operate as normal of other mechanism in the pneumatic system, even cause the generation of unintended consequence, functional reliability is poor, and existing filtration device structure complexity, unpick and wash difficulty, be unfavorable for that enterprise saves cost, increases the benefit.
Summary of the invention:
The purpose of this utility model is to solve above-mentioned filter and stops up back flow decline, causes the problem of pneumatic system cisco unity malfunction, and a kind of air cleaner with check valve that provides.
The purpose of this utility model is achieved through the following technical solutions: the air cleaner of band check valve, comprise copper pearl sintered filter core and be enclosed within its outer aluminium cup, fix a metal valve body on the filter, at check valve of the middle installation of air inlet and gas outlet of filter.In the utility model, check valve is vertically connected on the valve body by the nut screw thread by spool and spring.Further, aluminium cup and fixed head are fastened on the metal valve body by soket head cap screw, by sealing ring and valve seal.
Source of the gas gas is by in the air inlet input filter of air cleaner, and by the dust impurity in the copper pearl sintered filter core filtering gas pipeline, the gas behind the filtration, purification is by copper pearl sintered filter core, and the gas outlet that enters air cleaner outputs to the downstream work system.Filter is not before filter core stops up, air inlet and gas outlet gas pressure are in a basic balance, at this moment, check valve is in closed condition, when filter core is stopped up gradually by dust, throughput descends gradually, air inlet and gas outlet produce pressure differential, and when pressure reduction reached the design predetermined value, check valve was opened, air inlet gas satisfies the system works requirement by the system works that enters here.Open in case find check valve, the technical staff can unload the aluminium cup by loosening soket head cap screw from valve body, behind the cleaning copper pearl sintered filter core, refills on the valve body.
The utility model under the situation that the filter element flow reduces, by the unlatching of check valve, can satisfy the operate as normal of system, the functional reliability height by adopting technique scheme; In addition, the unlatching of check valve also points out the technical staff to clean copper pearl sintered filter core timely, guarantees the quality by gas.Adopt soket head cap screw that aluminium cup and valve body are fixed this technical scheme, can easily the aluminium cup be unloaded, copper pearl sintered filter core is cleaned.
Description of drawings:
Accompanying drawing is the cutaway view of the air cleaner of this band check valve.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
As shown in drawings with the air cleaner of check valve, comprise copper pearl sintered filter core 5 and be enclosed within its outer aluminium cup 7, fix a metal valve body 1 on the filter, check valve of the middle installation of air inlet and gas outlet at filter, check valve is vertically connected on the valve body by nut 2 screw threads by spool 4 and spring 3, aluminium cup 7 is fastened on the metal valve body 1 by soket head cap screw 8 with fixed head 6, by sealing ring 9 and valve body 1 sealing.
Claims (3)
1. the air cleaner with check valve comprises copper pearl sintered filter core and is enclosed within its outer aluminium cup, it is characterized in that, at check valve of the middle installation of air inlet and gas outlet of air cleaner.
2. air cleaner according to claim 1 is characterized in that, described check valve is vertically connected on the valve body by the nut screw thread by spool and spring.
3. air cleaner according to claim 1 and 2 is characterized in that, described aluminium cup and fixed head are fastened on the valve body by screw, by sealing ring and valve seal.
