Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1 and Fig. 2：The right-angle type emery wheel valve of the present invention, including valve body 1, emery wheel valve is provided with the inner cavity of valve body 1
Component, emery wheel valve module include the casing 11 for being nested in 1 inner cavity of valve body, the axis 6 being arranged in casing 11, the lower end connection of axis 6
There is upper emery wheel 7, spring 5, bearing 4 and thread bush 2 are arranged with successively from upper by lower in 6 periphery of axis；In the intracavity bottom of casing 1,
The lower section of upper emery wheel 7 is provided with lower emery wheel 9；Fluid through-hole 15, and upper emery wheel 7 are respectively arranged with upper emery wheel 7 and lower emery wheel 9
Outer end face with lower emery wheel 9 is respectively fluid outlet and fluid inlet；Spring 5, which is sleeved on axis 6 and provides axial force for axis 6, to be made
Emery wheel 7 and lower emery wheel 9 mutually compress；Lower emery wheel 9 and 11 inner wall of perisporium and casing between, between casing 11 and thread bush 2
And it is both provided with seal between 2 internal perisporium of 6 periphery wall of axis and thread bush.
The lower end of valve body 1 is provided with the inlet tube 10 communicated with the fluid bore 15 in lower emery wheel 9, on the side wall of valve body 1
It is provided with the outlet tube 12 communicated with the fluid bore 15 of upper emery wheel 7.
The casing 11 of the present invention be stainless steel sleeve pipe, is the undergauge section to emery wheel 9 under installing in the lower part of casing 1, institute
The lower end for stating lower emery wheel 9 is connected by short pin 14 with 1 intracavity bottom of valve body, 1 intracavity bottom of valve body set with inlet tube 10 and
The through hole that lower emery wheel 9 communicates.The extension diameter section of upper end to 1 inner cavity of valve body of the casing 11 of the present invention stops, i.e., is set on the top of valve body 1
Be equipped with one end extension diameter section, the extension diameter section be matching thread set 2 mounting structure, thread bush 2 coordinate with 1 inner cavity of valve body it is upper
Portion is the cylinder being adapted with extension diameter section, and lower part is the undergauge section being adapted with 11 internal diameter of casing, and thread bush 2 is by setting
Put the screw thread on its cylinder outside diameter and be opened in the screw thread of valve body extension diameter section internal perisporium and install to after in valve body 1, pass through
It is arranged on the cover board and screw in compression thread bush 2 of 1 upper surface of valve body.The hole for being offered to you and being pierced by 6 upper end of axis is said in cover board,
Since axis 6 needs to rotate, the axis hole for driving it to select, shaft hole matching spanner or other drives are additionally provided with 6 upper end of axis
Device and axle key are moved to coordinate to obtain 6 rotating moment of torsion of drive shaft.The middle part of axis 6 is provided with to install the boss of bearing 4.
Set bearing 4 purpose be sliding friction being changed into rolling friction, reduce the driving moment of emery wheel valve.
The lower face of bearing 4 is withstood in the upper end of spring 5, and the screens component for being arranged on 6 lower part of axis is withstood in the lower end of spring 5
On.The lower end of axis 6 and upper emery wheel 7 13 are fixedly connected by having strong market potential；Offered and upper emery wheel 7 in the lower end medium position of axis 6
The fluid cavity 16 (such as Fig. 1 and 2) that fluid passage communicates.Matched somebody with somebody between casing 11 and thread bush 2 by the sealing of multiple first sealing rings 3
Close installation.Sealed between lower emery wheel 9 and casing 11 by the second sealing ring 8 and coordinate installation.
Referring to Fig. 3 and Fig. 4：Fluid through-hole 15 in the upper emery wheel 7 and lower emery wheel 9 of the present invention is inclined hole.It is opened in
Inclined hole 15 in emery wheel 7 or lower emery wheel 9 is both provided with twice, twice inclined hole into " V " font (as shown in Figure 4), twice inclined hole
" V " font crosspoint is arranged at the outer end face of emery wheel 7 or lower emery wheel 9 as fluid outlet or fluid inlet.
In conclusion axis 6 13 is connected by having strong market potential for the present invention with upper emery wheel 7, emery wheel 7 is set to be rotated with axis 6；Short pin
14 are connected lower emery wheel 9 with valve body 1, prevent lower emery wheel 9 from rotating；Respectively there is a pair of of inclined hole on upper emery wheel 7, lower emery wheel 9, pass through axis
6 adjust the relative position of upper and lower 7,9 liang of device to hole of emery wheel, the open and close state of control valve and the size of flow
The course of work of the present invention is as follows：
It (can be manual spanner or other automatic driving machines to rotate by the driving mechanism for being arranged on 6 upper end of axis
Structure), make to rotate in sleeve 11 of the axis 6 in valve body 1, so as to drive emery wheel 7 to rotate, upper emery wheel 7 and lower emery wheel 9 are opposite at this time
Rotate, when a pair of of the inclined hole respectively having on upper emery wheel 7 and lower emery wheel 9 in rotation process slowly close to its, then valve of the present invention
Aperture slowly become larger, inlet tube and outlet tube are switched on, and fluid can pass through valve.If closing valve, instead
To chosen axis 6, valve is slowly turned down at this time, and after both inclined holes eat dishes without rice or wine to stagger completely, valve completely closes.The present invention's
" V " the font inclined hole set in most preferred embodiment is to be able to enable the aperture of valve more linear.
In conclusion the present invention realizes the opening and closing of valve using upper and lower emery wheel, using upper and lower emery wheel upper-lower compacting come real
Now seal, even if module has abrasion in mutual friction process up and down, but by the compression of spring, can ensure both all the time
Seal, cannot complete feelings so as to effectively prevent that component wear caused by valve has long-time use closes caused by
Condition.
