Abstract

A diverting filter valve comprises a water inlet pipe and a water outlet pipe, a filtering cavity is arranged on one side between the water inlet pipe and the water outlet pipe, a filtering screen assembly for filtering water is arranged in the filtering cavity, common portions of the filtering cavity wall, the water inlet pipe wall and the water outlet pipe wall are communicated, and a diverting oblique plate for guiding the water to flow into the filtering cavity is arranged between the water inlet pipe cavity and the water outlet pipe cavity. According to the diverting filter valve, the hemispherical filtering screen is adopted and fixed under an annular frame, the valve is simple and convenient to assemble and disassemble, and sewage in the filtering screen is easy to clean; the diverting oblique plate is arranged in the water inlet pipe, the filtering screen is lower than a water inlet, the sewage can be prevented from being flushed back into the water inlet pipe when the valve is closed and the filtering screen is taken out, and therefore the sewage in the filtering screen can be eliminated thoroughly.

Description

A kind of water conservancy diversion filter tap

Technical field

The utility model relates to water treatment system plumbing filter tap, refers more particularly to the water conservancy diversion Filter valve of water treatment pipeline, water circulation service conduit, purification apparatus use.

Background technique

In water treatment system, because foreign material are arranged in the water, in the pipeline of access water pump, filter tap (being generally Y type filter tap) can be installed all, foreign material in the isolated water guarantee that water pump is not stopped up and damages by foreign material, and water treatment system is normally moved.

Water treatment system is after operation a period of time, the foreign material that filter screen in the filter tap can be filtered fill up obstruction, affect flow, at this moment need to close the valve of filter tap front end, take the filter tap valve gap apart, take out filter screen, the cleaning and filtering net, clean and completely again overanxious net is put back in the valve body, tighten valve gap and can start the water pump feedwater, such as number of patent application 200620157048.4 " a kind of filter tap ".But when on the needs cleanings filter screen during foreign material, switch off the pump or valve after, because the water of backflow is arranged in the pipeline, foreign material can be along with in the water refunds intake pipe that refluxes in the filter screen.In addition, when installing space was limited, the filtration channel of Y type filter tap part can only upwards be installed, and because filter screen is bottomless cylindrical screen, the foreign material on the filter screen are easily fallen in the pipeline.The foreign material that at every turn leach can not thoroughly be cleared up, and can increase the number of times because of cleaning filter screen throttle down, so the structure of existing Filter valve awaits further to improve.

Summary of the invention

Technical problem to be solved in the utility model is to change the deficiency of existing Filter valve, designing a kind of Pipeline Water that prevents refluxes, avoid assorted dirt to be brought back in the intake pipe, reach assorted dirt in the thorough removing filter screen, remove and install conveniently filter screen valve.

The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of water conservancy diversion filter tap, comprise intake pipe and outlet pipe, it is characterized in that a side is established a filtering cavity between intake pipe and outlet pipe, establish the screen modules of a filtered water inlet in the described filtering cavity, described filtering cavity wall is connected with water inlet tube wall and the common part of water outlet tube wall, establishes the flow guiding inclined plate that a guiding water inlet flows into filtering cavity in the middle of described water inlet tube chamber and the water outlet tube chamber.

Described screen modules comprises filter frame, is located at the hemisphere filter screen of filter frame lower end, and is located at the frame cover of filter frame upper end.

Described filter frame is comprised of with the middle studdle that is connected upper and lower annulus frame upper and lower annulus frame.

The upper end of the spherical filter screen of described semicircle is clamped by the indent clip slot in the lower annulus frame.

The angle of cut of the center line of described intake pipe and outlet pipe and filtering cavity center line is 20～45 degree.

The beneficial effect of above-mentioned design is: adopt the hemisphere filter screen and filter screen is fixed under the annulus framework, remove and install simple and conveniently, easily remove the assorted dirt in the filter screen.In intake pipe, be provided with flow guiding inclined plate and filter screen is lower than water intake, can avoid assorted dirt by in the refunds intake pipe, from can thoroughly removing the assorted dirt the filter screen when throttle down takes out filter screen.

Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described in further details.

Referring to shown in Figure 1, the water conservancy diversion filter tap comprises intake pipe 1, outlet pipe 2, filtering cavity 3, the screen modules of in filtering cavity, establishing a filtered water inlet, and described screen modules comprises filter frame 4, be located at the hemisphere filter screen 5 of filter frame 4 lower ends, and be located at the frame cover 8 of filter frame 4 upper ends.Described filtering cavity 3 walls are connected with intake pipe 1 wall and the common part of outlet pipe 2 walls, establish the flow guiding inclined plate 6 that a guiding water inlet flows into filtering cavity 5 in the middle of water inlet tube chamber 12 and the water outlet tube chamber 13, the vertical and intersectant centerline of described flow guiding inclined plate 6 and filtering cavity 3.The lower annulus 7 of filter frame 4 is connected with flow guiding inclined plate to connect and is supported by being located at step 14 on the filtering cavity wall.Intake pipe and outlet pipe are the mutual butt tube of same center line, and the center line of intake pipe and outlet pipe and the filtering cavity center line angle of cut are 20～45 degree.

Shown in Fig. 2～4, filter frame 4 is comprised of with the strut 11 of centre upper annulus 9, lower annulus 7, and strut 11 can be established 3～4, and the present embodiment is established 4, as shown in Figure 4.Lower annulus 7 lower edges are established annulus inner groovy 10, with the corresponding fastening of upper limb size of hemisphere filter screen 5.Filter screen 5 is woven into hemisphere by Stainless Steel Wire, and filter screen 5 is contained in below the filter frame 4, by the lower annulus 7 of filter frame 4 establish to the fastening of helping each other mutually of lower convex platform rank and filtering cavity 3 inwall steps 14.Filter screen 5 just in time is located at the below of flow guiding inclined plate 6 elongation lines, and the annulus that filter screen 5 opens faces toward feed water flow to communicating with intake pipe 1.

Referring to shown in Figure 1, filtering cavity 3 generally is located at the top of pipeline, filter screen is packed into behind the pipeline, current enter into water tube chamber 12, under the effect of flow guiding inclined plate 6, enter filtering cavity 3,5 outflows enter water outlet tube chamber 13 through filter screen, the dirt of mixing in the water when water flows through filter screen 5 is left in the hemisphere filter screen, remove filter frame lid 8 valve gaps of outwarding winding when mixing dirt in the filter screen 5 and open, and takes out filter frame 4, put into filtering cavity 3 after filter screen 5 cleaned up, since flow guiding inclined plate 6 stop and the filter screen water level is higher than the outlet pipe water level, avoid backwater to flow out, and mounting or dismounting are cleaned quick and convenient.
