Specific embodiment
With reference to the accompanying drawing and specific embodiment is further elaborated the utility model.
As shown in Figure 1, a kind of spool 2 of dilution water valve of the present embodiment, spool 2 is in ladder circle column, including is coaxially set
The valve rod 21 and actuating station 22 set, and the diameter of valve rod 21 is less than the diameter of actuating station 22.Valve rod 21 is for connecting driving valve
The driving device that core 2 rotates (is not shown in the figure, existing motor, air pressure rotating cylinder or hydraulic rotating cylinder etc. can be used existing
Technology is realized), annular groove 211 is offered on the periphery of valve rod 21, and the first sealing ring 6 is equipped in annular groove 211, is used for
Sealing between valve seat 1 and valve rod 21.Flat mouth 212 is fixed with away from one end of actuating station 22 in valve rod 21；Flat mouth 212 is in valve rod
21 with play the role of key in the connection of driving device, for the torque of driving device to be passed to spool 2, to drive spool 2
Rotation.There is in actuating station 22 away from one end of valve rod 21 the radial support section 222 being adapted to valve seat 1；Pass through radial support section
222 and valve rod 21, making entire spool 2 is in the state of simply supported beam, and stress is simple, and stress is small.In actuating station 22 close to valve rod
21 one end is block section 221, and driving device drives spool 2 to rotate, to be opened or closed on valve seat 1 by block section 221
Inlet opening 11.It is understood that radial support section 222 can also be respectively provided at the both ends of block section 221.According to applicant
Protrude into research, caused by causing spool 2 is stuck to be primarily due to spool 2 and 1 incrustation of valve seat, for this reason, it may be necessary to reduce spool 2 with
Contact area between valve seat 1 is to avoid incrustation, to avoid spool 2 stuck.Specifically, it in the present embodiment, uses with lower section
Formula reduces the contact area between spool 2 and valve seat 1: making the axial length L 1 of radial support section 222 and the axis of block section 221
It is L1:L2=1:(4.1-5.3 to the ratio between length L2)；And the size in the face that block section 221 is in contact with valve seat 1 is slightly larger than
Opening size of the inlet opening 11 of the valve seat 1 towards one end of the spool 2.It should be noted that the block section 221 with
The size in the face that valve seat 1 is in contact has slightly larger than the opening size of inlet opening 11 towards one end of the spool 2 of the valve seat 1
Body refers to that the size of all directions in the face that block section 221 is in contact with valve seat 1 is slightly larger than inlet opening 11 towards spool respectively
The size of the opening respective direction of 2 one end.Specifically, if inlet opening 11 is cylindrical hole, block section 221 and valve seat
The size of 1 face being in contact in all directions is slightly larger than the diameter of cylindrical hole.Slightly larger than referring to block section 221 and valve seat 1
The face being in contact can just block inlet opening 11 towards the opening of one end of the spool 2 without revealing.In spool 2
The water inlet 223 that spool 2 is offered on block section 221, in radial support section 222 on the end face of one end of block section 221
Offer the water outlet 224 being connected to the water inlet 223.Dilution water enters dilution water valve from the inlet opening of spool 1 11, so
This dilution water valve successively is flowed out by water inlet 223, water outlet 224 and spool mounting hole 12 afterwards.
For convenience of the processing of spool 2, the difficulty of water inlet 223 is reduced, in the present embodiment, as shown in Figure 1, in the closure
The water inlet 223 of the spool is opened up in section 221；Water inlet 223 is on the face of axis of rotation for being parallel to the block section 221
Projection it is U-shaped, and the axis of rotation of the U-shaped central axes vertical blocking section 221.Preferably, in the present embodiment, in institute
The open end for stating water inlet 223 is provided with chamfering 2231.On the one hand preventing water inlet 223 from scratching valve seat 1 on the other hand can
Greatly reduce the contact area between valve seat 1 and spool 2.
As Figure 2-3, one of the present embodiment dilutes water valve, including above-mentioned spool 2, further include be socketed in it is described
Valve seat 1 outside spool 2；In the block section 221 away from one end of radial support section 222 and the radial support section 222 back
One end from block section 221 is respectively arranged with the first gasket ring 3 and the second gasket ring 4；First gasket ring 3 is made of polytetrafluoro, the first pad
Ring 3 is arranged between the valve seat 1 and block section 221；Second gasket ring 4 is made of polytetrafluoro, and the second gasket ring 4 is arranged described
Between valve seat 1 and radial support section 222.First gasket ring 3 and the second gasket ring 4 made of polytetrafluoro are not easy incrustation, and not with valve
The rotation of core 2 and rotate.Valve seat 1 in the present embodiment as shown in figure 3, offer that central axes intersect vertically on valve seat 1 into
Water hole 11 and spool mounting hole 12, and valve seat 1 is run through in one end of spool mounting hole 12, to facilitate the installation of spool 2.Spool peace
The bottom hole in dress hole 12 offers the through-hole 13 coaxial with spool mounting hole 12, to install valve rod 21.In the hole of spool mounting hole 12
Mouth is provided with outlet pipe 5, and outlet pipe 5 directly can be fixed on valve by the existing non-removable connection type such as welding or bonding
On seat 1.To the second gasket ring 4 of limitation, the axial displacement of actuating station 22 and the first gasket ring 3.In the present embodiment, for convenience of maintenance and
Maintenance, as shown in Fig. 2, outlet pipe 5 is detachably connected with valve seat 1.Specifically, outlet pipe 5 is provided with method close to one end of valve seat 1
Orchid offers multiple connecting holes on flange, screw is provided in connecting hole, the spiral shell connecting with screw thread is offered on valve seat 1
Pit, also, the second sealing ring 7 is set between the end face of the flange of outlet pipe 5 and valve seat 1, to guarantee outlet pipe 5 and valve seat
