Description

Strong-sealing type valve cover for plug-in valve

Technical Field

The utility model relates to a push-pull valve accessory technical field especially relates to a strong canned type valve gap for valve of picture peg.

Background

At present, a gate valve is a main control device for the flow or conveying capacity of powder, crystal granules, granules and small materials, and is widely used in industries such as metallurgy, mines, building materials, grain, chemical engineering and the like to control flow change or rapidly cut off. The gate valve mainly comprises a frame, a gate plate and other parts, and when the gate valve works, the gate plate reciprocates along a certain direction to achieve the purpose of opening and closing the gate.

In the petrochemical industry, in order to cut off powdery materials such as PTA, CPE, PVC, etc. quickly and conveniently, a pneumatic gate valve is often adopted. At present, the valve cover of the gate valve is poor in sealing performance and is opened and closed flexibly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a strong canned type valve gap for picture peg valve, simple structure can improve the leakproofness between valve gap and the valve plate and open and close the security.

In order to achieve the purpose, the utility model provides a strong canned type valve gap for plug board valve, including the body, the body is integrative structure, the body includes sealed face and installation face, the installation face with be connected through the connecting pipe between the sealed face, sealed face is runway-shaped, the installation face is circular, the size of installation face is less than the size of sealed face, the outer edge of sealed face is equipped with the mounting disc that is used for being connected with the valve body, the outer edge of installation face is equipped with the fixed disk that is used for with logical union coupling, be equipped with the sealing washer on the inner edge of fixed disk;

an annular clamping groove is formed in the inner edge, close to the sealing surface, of the connecting pipe, and an annular sealing strip is arranged in an annular limiting seat on the clamping groove.

Preferably, a groove located on the outer side of the clamping groove is formed in the sealing surface, the groove comprises a first groove and a second groove which are distributed at intervals, the first groove is located on the outer side of the second groove, and the outer edges of the first groove and the second groove are consistent with the outer edge of the sealing surface in shape.

Preferably, the size of the second groove is larger than that of the first groove, and the size of the connecting pipe is smaller than half of the size of the sealing surface.

Preferably, the sealing strip is a ceramic ring.

Therefore, the utility model adopts the above structure a strong canned type valve gap for picture peg valve, simple structure can improve the leakproofness between valve gap and the valve plate and open and close the security.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Reference numerals

1. A sealing surface; 2. a mounting surface; 3. a connecting pipe; 4. mounting a disc; 5. fixing the disc; 6. a seal ring; 7. an annular limiting seat; 8. a sealing strip; 9. a first groove; 10. a second groove.

Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model relates to a picture peg is preceding view of strong canned type valve gap embodiment for valve, fig. 2 is the utility model relates to a picture peg is rear view of strong canned type valve gap embodiment for valve, as shown in the figure, a picture peg is strong canned type valve gap for valve, including the body, the body is structure as an organic whole, and the body includes sealed face 1 and installation face 2, is connected through connecting pipe 3 between installation face 2 and the sealed face 1, and sealed face 1 is the runway shape, and installation face 2 is circular, and the size of installation face 2 is less than the size of sealed face 1. The size of the connecting pipe 3 is smaller than half of the size of the sealing surface 1, so that the sealing surface 1 provides a movement space for opening and closing the valve plate at the connecting pipe 3. The outer edge of the sealing surface 1 is provided with a mounting disc 4 used for being connected with the valve body, and the body is connected with the valve body through the mounting disc 4. The outer edge of the mounting surface 2 is provided with a fixed disk 5 used for being connected with a material passing pipe, and the mounting surface 2 is connected with the material passing pipe through the fixed disk 5. The sealing ring 6 is arranged on the inner edge of the fixed disc 5, and the sealing performance of the connection between the mounting surface 2 and the material passing pipe is enhanced due to the arrangement of the sealing ring 6.

Be equipped with ring groove on the interior edge that is close to sealed face 1 on connecting pipe 3, be equipped with annular sealing strip 8 in the spacing seat of annular 7 on the draw-in groove, sealing strip 8 is the ceramic ring, and the setting of sealing strip 8 has improved the leakproofness of sealed face 1.

Be equipped with the recess that is located the draw-in groove outside on sealed face 1, the recess includes first recess 9 and the second recess 10 of interval distribution, and first recess 9 is located the outside of second recess 10, and the size of second recess 10 is greater than the size of first recess 9, and the outer edge of first recess 9, second recess 10 all is unanimous with the outer edge shape of sealed face 1. In the process of opening and closing the valve plate, the friction resistance between the valve plate and the sealing surface 1 is weakened by the arrangement of the groove. In addition, the first grooves 9 and the second grooves 10 are distributed in a separated mode to weaken the opening and closing resistance of the valve plate and meanwhile provide support for the valve plate, the opening and closing safety of the valve plate is guaranteed, the situation that the valve plate is not opened and closed in place cannot occur, and in addition, the overall weight is reduced due to the arrangement of the grooves.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
