Brief description
Fig. 1 is the generalized section of this utility model switching valve.
Fig. 2 is the schematic perspective view with handle cooperation for the valve element of this utility model switching valve.
Fig. 3 is 2 three-dimensional exploded view.
Fig. 4 is the viewgraph of cross-section of this utility model switching valve.
Specific embodiment
Refer to shown in Fig. 1 to Fig. 4, this utility model switching valve 10 includes a valve body 10, being contained in valve body 10
Valve element 20, insertion valve body 10 in a plunger 30 and valve element 20 is positioned the locating shaft 40 on plunger 30.
Valve body 10 includes upper valve body 11 and lower valve body 12, and upper valve body 11 is supported in lower valve body 12, is formed between the two
One cavity 13, upper valve body 11 is provided with feed liquor runner 110 and upper discharge opeing runner 111, lower valve body 12 be provided with from upper discharge opeing runner 111 to
The lower discharge opeing runner 120 of lower extension, feed liquor runner 110 and upper discharge opeing runner 111 respectively with cavity 13 insertion.Upper discharge opeing runner
111 form discharge opeing runner with lower discharge opeing runner 120.
Valve element 20 is uprightly contained in cavity 13, and elasticity compresses the medial wall of cavity 13.Valve element 20 is in the vertical direction
Curved, it includes an arcwall 21, an endoporus 22, an opening 23 and a pair of fixing hole 24, and arcwall 21 encloses located at endoporus 22
Outside, opening about 23 and laterally runs through arcwall 21 so that valve element 20 can be with opening and closing in circumferencial direction, and fixing hole 24 laterally passes through
Wear arcwall 71, plunger 30 is downwardly in endoporus 22, and the lateral surface of arcwall 71 is located on same periphery, but medial surface exists
It is in undulated on circumferencial direction, increased the elasticity tension of valve element 70.
Valve element 20, due to being provided with opening 23, promotes valve element 20 to keep the state expanding in cavity 13, is close to cavity
On 13 medial walls, both gaps are zero, improve sealing effectiveness, to the dimensional fits required precision between valve element 20 and valve body 10
Low, even if valve element 20 weares and teares, tension force also can be relied on to be close on cavity 13 medial wall it is ensured that the function of switching valve 100, favorably
In the service life extending switching valve 100.
Plunger 30 bottom is downwardly into cavity 13, and inserts in the endoporus 22 of valve element 20.Plunger 30 is provided with and laterally runs through
The slit 31 of plunger 30, slit 31 is also downward through plunger 30.
Laterally through slit 42, fixing hole 24 is fixed in two ends to locating shaft 40, so configured, and plunger 40 can drive valve
Core 70 rotates.
During this utility model switching valve 10 work, first, plunger 30 band movable valve plug 20 rotates a predetermined angular so that opening
23 are alignd with feed liquor runner 110, but stagger with upper discharge opeing runner 111, and liquid flows to after opening 23 from feed liquor runner 110, enter
Cavity 13.Then, plunger 30 band movable valve plug 20 further rotates a predetermined angular, and feed liquor runner 110 is by the arcwall of valve element 20
21 cover, and stagger with opening 23, and opening 23 is alignd with upper discharge opeing runner 111.Then, valve element `20 is static, and plunger 30 is to moving down
Dynamic, compressed liquid, promote liquid to extrude valve body 10 from upper discharge opeing runner 111, lower discharge opeing runner 120.
Although being example purpose, have been disclosed for preferred implementation of the present utility model, the common skill of this area
Art personnel by it is realized that disclosed in without departing from by appending claims scope and spirit of the present utility model situation
Under, various improvement, increase and replacement are possible.
