Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described, but protection domain of the present utility model is also
It is not limited to this.
As Figure 1-3, anti-blocking resistance to erosion two way seal of the present utility model regulation valve, including valve body 2 and valve gap 3, valve
Body 2 is provided with valve component 5, and valve component 5 is provided with valve ball 4, is respectively equipped with valve rod 6 and lower axle above and below valve ball 4
1, the outside of valve rod 6 is provided with gland 7, and the outside of gland 7 is provided with support 9, is provided with filler 8 between gland 7 and valve rod 6.
Valve component 5 in this utility model is single without intrusive mood, Bidirectional seal structure, the primary seal of valve component 5
Direction is that valve seat 51 end flows to valve ball 4 end, and valve ball 4 port of export is without valve seat.Valve ball 4 is fixed whole spherical structure, by lower axle 1 and valve
Bar 6 coaxial center retrains, and valve ball 4 carries out spinning movement along the coaxial centerlines of lower axle 1 and valve rod 6.Hole slot is said on valve ball 4
43, hole slot 43 coordinates with valve rod 6, and valve ball 4 is provided with runner, and runner includes inlet channel 41 and outlet flow 42, and runner is non-
Circle, the entrance point of runner is approximation " Δ " shape, and the discharge characteristic according to specific requirement is accurately arranged by its true form.
The port of export of runner is combined by two various sizes of semicircles, semicircle size be more than standard circular channel size, two and half
Circle combined shaped is oval, the figure of eight or " О " shape；Valve body 2 and valve gap 3 are respectively provided with the straight-through circular flow channel of concentric, valve
Lid 3 is provided with medium entrance end, and valve body 2 is provided with runner exit end.
Valve component 5 in this utility model comprises valve seat 51, and valve seat 51 is provided with spring base 53, and spring 54 is arranged on
In spring base 53, and being provided with trim ring 55 between spring 54 and rectangular seal 56, the front-end and back-end of spring 54 are separately installed with
Inverted trapezoidal sealing ring 52 and rectangular seal 56, inverted trapezoidal sealing ring 52 and rectangular seal 56 by the most airtight for spring 54, every
From any material and the intrusion of medium.
As preferably, the rectangular seal 56 in this utility model is positioned at the import front end, primary seal direction of valve seat 51,
Inverted trapezoidal sealing ring 52 is positioned at the import rear end, primary seal direction of valve seat 51, and valve seat 51 is provided with and valve in rectangular seal 56 front end
Cover the valve seat tail end 512 of 3 internal diameters, and the internal diameter size a2 of rectangular seal 56 seals the chi of center line more than valve seat 51 and valve ball 4
Very little a1.
The sealing surface both sides of the valve seat 51 in this utility model are provided with sharp edge along 511.In valve ball 4 rotary movement
Valve ball 4 surface material can be struck off and cleans, it is also possible to by spheroid approximation " Δ " shape runner mouth and the cooperation of valve seat
The material such as banding, strip is sheared and blocked.
The tunnel inlets end of valve ball 4 surface, valve seat 51 sealing surfaces and valve ball 4 in this utility model is all hardened
Process.
Using technique scheme, valve component 5 is arranged on valve ball 4 import front end, and valve ball 4 rear end does not has valve seat and any
Other similar settings, direct and pipeline communication, and also valve component 5 designs for Bidirectional seal structure, and the chamber of spring 54 is nothing
Intrusive mood, fully seal structure design, when medium flows according to primary seal direction (arrow direction indication), valve seat 51 is at spring
It is close to valve ball 4 under 54 effects and medium power effect realize sealing, and when buffer brake is bigger, due to the square of valve seat 51 front end
The internal diameter size a2 of shape sealing ring 56 seals size a1 of center line more than valve seat 51 and valve ball 4 and forms ring surface " b ", is reversely situated between
Matter pressure is multiplied by ring surface " b " and i.e. produces the deboost F of valve seat 51, and makes valve seat 51 be close to valve ball 4 and realize reversely sealing,
But be gradually opened valve be adjusted effect time, fluid first by spheroid 4 approximate " Δ " shape most advanced and sophisticated small flow channels flow out, now by
In valve ball 4 rear end approximate ellipsoidal, the figure of eight or " О " shape, runner relatively standard runner size " D " is bigger, and fluid can not be straight
Connect be washed into valve ball 4 port of export any physically, along with the continuous increase of valve opening, approximation " Δ " shape runner mouth will more come
The biggest, output flow is also with increase, and valve ball 4 rear end, owing to entirely without obstruction, medium circulation is without hindrance, is not stagnated, without blocking,
And discharge characteristic as requested is accurately calculated and arranges by the true form that inlet channel 41 approximates " Δ " shape runner mouth,
Inlet channel 41 approximate " Δ " shape runner mouth with the routing motion of valve seat 51 material such as banding, strip can also be sheared and
Block.
Therefore, this utility model can thoroughly solve solid particle or containing the complicated stream such as solid medium, ribbon-like fibre medium, paper pulp
Body, high-pressure fluid carry out accurate flow adjustment, and is in case of emergency capable of two way seal, meet high parameter, spy
Accurately regulation and bidirectional cutting function under different operating mode, it is ensured that production run and the Effec-tive Function of operation and long-term safety reliably should
With.
Above-described embodiment is only used for illustrating utility model of the present utility model design, rather than to this utility model right
The restriction of protection, all changes utilizing this design that this utility model carries out unsubstantiality, guarantor of the present utility model all should be fallen into
Protect scope.
