When the first side filter mouth 16 and second side filter mouth 26 on filter hole can filter out the impurity in liquid, pass through pull valve rod 5, valve rod
5 drive the first spool 7 and the movement of the second spool 11, and when all closures of the first valve body 3, the second valve body 13 is fully open, liquid
The second spool 11 is flowed to from valve internal, then the throttling element 6 flowed to after stream on the second valve body 13 is subtracted by the second unhurried current plate 12,
Second unhurried current plate 12 reduces the spiral shape that liquid is equipped with for reducing fluid flow rate the impact force of the second spool 11, throttling element 6
Groove 28 and unhurried current circle 27, to reduce flow velocity and flow of the fluid in the second water outlet 10, by pulling valve rod 5, when the
When two valve body 13 is all closed, the first valve body 3 is fully open, and liquid flows to the first spool 7 from valve internal, then slow by first
Flowing plate 9 flows to the throttling element 6 on the first valve body 3, flows to the first water outlet 8 finally by throttling element 6, throttling element 6 is by the first valve
The opening direction of core 7 and the second spool 11 successively increases, and is conducive to adjust flow velocity and flow, when pulling valve rod 5, the first spool 7
Or second spool 11 it is not completely closed when, liquid can flow to the first water outlet 8 and the second water outlet 10, valve rod sealing device respectively
The effect of the dustband 30 of 4 upper ends is that external dust and the foreign matter being attached on valve rod 5 is prevented to enter the close device 4 of valve rod, is prevented
Damage valve rod 5；First rubber ring 35 and second its side of rubber ring 34 are squeezed, and keep it lateral by its flexible deformation
Preload force keeps valve rod 5 to seal；There is stainless steel leaf spring inside the general plug envelope 32 of lower end, respectively to the radially inner and outer bullet of valve rod 5
Property deformation, when having pressure inside the first valve body 3, fitting valve rod 5 that can be closer keeps sealing, and sealing effect is good, it is ensured that
No leakage.
The beneficial effects of the utility model are: having filtering function, anti-blockage function and high leakproofness, valve body is improved
Service life increases throttling element, can good control flow, improve the flexibility that valve uses.
