Abstract
The utility model a non-dismantling self purification strainer valve, mainly comprising a valve body (1), a valve core (2), a filter mesh (3), a valve rod (4) and a handle(5), which is characterized in that: three mutual communicated fluid channels are arranged on the valve body (1); the valve core (2) is a hollow spherical housing provided with three holes for communicating the flows; wherein, the filter mesh (3) is arranged in one hole. The utility model has the advantages of simple structure, convenient operation, large circulating area, high filter efficiency, low resistance loss, strong practicability and wide application.
Description
Affiliated technical field
The utility model relates to a kind of valve, is mainly used in industry and the civilian pipe-line system, plays a part to filter and turn-off.
Background technique
At present, the filtrating equipment in the pipe-line system mainly is filter of series connection, and a valve is respectively adorned in the inlet/outlet both sides of filter.Under the filtration state, two valves are open-minded; In the time of need taking the filter cleaning apart, close two valves.Such device pipeline accessory is many, take up room big, and is during maintenance and repair, time-consuming bothersome again.The filter tap that valve and filter are combined can solve the deficiency of above-mentioned filtrating equipment, but also there are some shortcomings in present filter tap (number is 89209166 as Chinese patent application), as complex structure, the fluid passage is elongated, screen area is little, thereby cause operation and maintenance trouble, filter efficiency is low, fluid impedance losses is big.
Summary of the invention
The purpose of this utility model and task are the above-mentioned shortcomings that will overcome filter tap, and a kind of simple in structure, easy to use, maintenance is quick, filter efficiency is high, drag losses is little novel filter tap is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the utility model mainly is made up of valve body (1), spool (2), filter screen (3), valve rod (4), handle (5), it is characterized in that, valve body (1) has three fluid passages that are interconnected, spool (2) is the spherical shell of a hollow, filter screen (3) is equipped with in the hole that three through-flow bodies are arranged on it on one of them hole.
The axes intersect one-tenth of (1) three fluid passage that is interconnected of described valve body "
" shape, the transverse section of passage is circular, the intersection of three fluid passages that are interconnected is spherical hollow spaces; The hole of last three the through-flow bodies of spool (2) is circular, its axes intersect one-tenth "
" shape; Filter screen (3) is cup-shaped, and its side surface is vertical with the bottom surface.
Spool (2) is contained in the spherical hollow space of valve body (1), and filter screen (3) is contained in the hole of spool (2), and the rim of a cup that makes filter screen (3) is in face of flow direction.Hole on the spool (2) various combination corresponding with the passage of valve body (1) can be realized four kinds of working staties: the filtration state is (blowdown valve that is contained on the sewage draining exit can not cut out, and does not draw among this valve figure) 1.; Just washing state; The filtration state is (blowdown valve that is contained on the sewage draining exit must cut out, and does not draw among this valve figure) 2.; The backwash state.
The utility model compared with prior art has the following advantages and beneficial effect: simple in structure, easy to operate, circulation area is big, the filter efficiency height, and drag losses is little, and is practical, applied range.
Below in conjunction with drawings and Examples the utility model is further specified.
