When opening is impacted by high-pressure medium, opening voluntarily, both sides firmly prop up the sidewall of groove by the pressure of medium, prevent from being situated between
Matter is revealed, and is additionally, since the special construction that recess sidewall is opening-like, it is possible to increase the protection face of explosion-proof sealing ring further
Long-pending.
Further, described left and right valve body is all integrally formed with reinforcement, each reinforcement structure the most twist difference
Correspondence is set around the surface of left and right valve body.
By using technique scheme, utilize the reinforcement of helical structure, enhance the radial direction resistance to compression of two valve bodies
Ability, the active force that valve body media passage is brought by dispersion high-pressure medium, improves the anti-pressure ability of valve.
Further, on described left valve barrel, the hand of spiral of reinforcement is contrary with the hand of spiral of reinforcement on right valve barrel.
By using technique scheme, it is contemplated that fluid media (medium) exists rotation direction, and different rotation directions makes the shearing resistance of pile tube
Ability can also be strengthened.
The beneficial effects of the utility model are, improve sealing and the longevity of sealing of two valve body junctions of valve
Life, strengthens the comprcssive strength at this simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As it is shown in figure 1, the present embodiment includes left valve barrel 1, right valve barrel 2, valve rod 3 and handle 4, having of left and right valve body 2
The medium channel 6 of same diameter, the outer surface of left and right valve body 2 is designed with reinforcement 5, and reinforcement 5 the most integrally waters with valve body
Type casting moulding, reinforcement 5 structure the most twist on two valve bodies, rotating around being located at the surface of left and right valve body 2, by test,
The present embodiment is by left with the spiral of reinforcement 5 on right valve barrel 2 for the hand of spiral of reinforcement 5 on left valve barrel 1 rightabout design.
Meanwhile, in conjunction with in Fig. 2 Yu Fig. 4 it can be seen that the end face of left sealing surface 11 is provided with a left side for some structures ringwise
Seal convexity 14, the surface of left seal convexity 14 offers 12,3 grooves of left groove of at least 3 loop configuration and leads to medium
Road 6 is in concentrically ringed structure, and the medium channel 6 of left valve barrel 1 is positioned at the ring of left seal convexity 14.
In conjunction with Fig. 3 to Fig. 4 it can be seen that right valve barrel 2 is provided with the similar right sealing surface 21 of left sealing surface 11 structure, right
The end face of sealing surface 21 is provided with right seal convexity 24 with right groove 22, result and left groove 12, the identical (left side of left seal convexity 14
Groove 12, right groove 22 are all used to place sealing ring), as left sealing surface 11, all use the side of formed by integrally casting molding
Formula is made.
In conjunction with Fig. 2 to Fig. 4, left and right seal convexity 24 is provided with the cannelure 13 and annular lines 23 matched, and left and right
The most trapezoidal structure of axial cross section of seal convexity 24.
Then, in conjunction with Fig. 1 with Fig. 4 it can be seen that the present embodiment left seal convexity 14 is abutted with right seal convexity 24,
Separated by groove, it is possible to reduce add the difficulty in man-hour, it is ensured that two relative sealing surfaces can complete laminating；Cannelure 13 with
The design that annular lines 23 coordinates, is by increasing the contact area between two sealing surfaces, improve further sealing property with
Comprcssive strength, the design of annular lines 23, moreover it is possible to when seal failure, produce resistance by the passage of self bending, offset one
The pressure medium of part, prevents medium ejection at a high speed at this.
Additionally, left groove 12 is opening-like with the cross section of right groove 22, cross section is similar to isosceles trapezoidal structure, and sidewall is to incline
Oblique, it is used for closely placing sealing ring.
From Fig. 4 from it can be seen that the sealing ring in the left groove 12 that medium channel 6 is farthest is explosion-proof sealing ring 7, anti-
Quick-fried sealing ring 7 design different from common sealing ring, the one side at relative medium passage 6 is provided with opening 71, axial cross section in
" U " type structure, when installing, fixing, the opening 71 on explosion-proof sealing ring 7 need to be subject to towards medium channel 6 competence exertion effect
During to the impact of high-pressure medium, opening voluntarily, both sides firmly prop up left groove 12 and the side of right groove 22 by the pressure of medium
Wall, prevents medium from revealing.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
