Description

Valve deck

Technical field

The utility model is related to the components on a kind of valve, and in particular to a kind of valve deck.

Background technology

Ball valve is mainly used for blocking or connects the liquid medium in valve body, also the adjusting and control available for liquid medium, Ball valve includes ball valve body, core, valve rod and sealing ring.Ball valve body usually requires to be arranged to the structure of split, in order to Core is packed into valve body, therefore ball valve body includes the valve body of placement core and is placed in the valve decks of valve body both sides, valve body and The mounting groove for sealing ring installation is equipped on the inside of valve deck, the ball valve after installation is by the sealing ring and core in mounting groove Connection is contradicted, so as to form the leakproofness of core and ball valve body.On valve deck there is connecting flange, pass through the connecting flange and pipe The flange seal connection of road end, however pipeline is susceptible to poorly sealed situation with the connection with valve body in the prior art, Liquid in ball valve is caused easily to generate leakage in high-pressure process.

The content of the invention

To solve the above problems, the purpose of this utility model is to provide a kind of connection sealing it is good, it is high pressure resistant and knot The reliable valve deck of structure.

To achieve the above object, the utility model provides following technical solution：A kind of valve deck, including valve deck body, institute The valve deck body stated is equipped with through hole, connecting flange is equipped in one end of the valve deck body, on the end face of the connecting flange Seal groove equipped with annular, the section of the seal groove is " V "-shaped, the sealing filled with annular in the seal groove Ring has on the inner face of the sealing ring and matches with the seal groove and in the built-in end of inverted " v " shape, in the sealing Other end of the ring away from the built-in end is sealed end, and the sealed end is equipped with the cricoid sealing being radially arranged in order Tooth, the outer edge of the sealed end towards being respectively equipped with arc-shaped abutting convex block on the inner face of the connecting flange, The middle part of the seal face is additionally provided with isolation groove, and isolation ring is filled in the isolation groove.

The adsorption tank of arc shape, the suction are respectively equipped on the both sides side wall that the built-in end is in contact with the seal groove Attached slot distinguishes annular spread at regular intervals along the both sides side wall of the built-in end, in the ring that completely cuts off towards the isolation groove The end face of bottom is equipped with two legs of distribution in a certain angle, and the end face of two leg is distributed towards the adsorption tank, institute Isolation bottom portion of groove is stated to be equipped with and the two corresponding triangular grooves of leg.

This structure of the utility model, valve deck are connected by connecting flange with the flange bolt on pipeline, connecting flange On sealing ring tooth sealed by it press on the end face of flange on pipeline, realize sealing isolation, and the sealing on sealing ring The abutting convex block at end can squeeze sealing tooth, improve sealing effect, risen in the isolation ring of the middle part of seal face The effect of sealing isolation is further improved to second protection, while improves the high pressure resistant effect of valve deck connection, is so just realized Connection sealing is good, the reliable technique effect of high pressure resistant and structure.

The utility model is further described with reference to the accompanying drawings and detailed description.

Description of the drawings

Fig. 1 is the stereogram of specific embodiment of the present invention；

Fig. 2 is the cut-away illustration of specific embodiment of the present invention；

Fig. 3 is the enlarged drawing of A in Fig. 2.

Specific embodiment

The utility model is specifically described below by embodiment, is served only for carrying out the utility model further Explanation, it is impossible to be interpreted as the restriction to scope of protection of the utility model.

As shown in Fig. 1-Fig. 3, the utility model discloses a kind of valve decks, and including valve deck body 1, valve deck body 1 is equipped with Through hole 11 is equipped with connecting flange 2 in one end of valve deck body 1, and the end face of connecting flange 2 is equipped with the seal groove 3 of annular, sealing The section of slot 3 is " V "-shaped, the sealing ring 4 filled with annular in seal groove 3, has and sealing on the inner face of sealing ring 4 Slot 3 matches and is in the built-in end 41 of inverted " v " shape, is sealed end 42 in other end of the sealing ring 4 away from built-in end 41, close Sealing end 42 is equipped with the cricoid sealing tooth 421 that is radially arranged in order, and the outer edge of sealed end 42 is towards connecting flange 2 Arc-shaped abutting convex block 43 is respectively equipped on inner face, isolation groove 44 is additionally provided in the middle part in 42 face of sealed end, every Filled with isolation ring 5 in exhausted groove 44.

The adsorption tank 45 of arc shape, adsorption tank 45 are respectively equipped on the both sides side wall that built-in end 41 is in contact with seal groove 3 Distinguish annular spread at regular intervals along the both sides side wall of built-in end 41, completely cut off end face of the ring 5 towards 44 bottom of isolation groove Two legs 51 of distribution in a certain angle are equipped with, the end face distribution of two legs 51 completely cuts off 44 bottom of groove towards adsorption tank 45 Equipped with two legs, 51 corresponding triangular groove 441.When completely cutting off in the isolation groove 44 of 5 stress indentation sealing ring 4 of ring, completely cut off ring Two legs 51 on 5 can drive the cell wall for squeezing triangular groove 441, since leg 51 is towards adsorption tank 45 so that in adsorption tank 45 Air can squeeze discharge, so sealing ring 4 can be made to be adsorbed by adsorption tank 45 in seal groove 3, certainly can on sealing ring 4 Some sticky fluid are smeared, can so make adsorption capacity more preferable, improve the effect of reliability of structure and sealing.

This structure of the utility model, valve deck are connected by connecting flange 2 with the flange bolt on pipeline, connecting flange Sealing ring 4 on 2 seals tooth 421 by it and presses on the end face of flange on pipeline, realizes sealing isolation, and on sealing ring 4 Sealed end 42 abutting convex block 43 can to sealing tooth 421 squeeze, improve sealing effect, the middle part in 42 face of sealed end Position isolation ring 5 and play second protection further improve sealing isolation effect, while improve valve deck connect high pressure resistant effect Fruit, isolation ring 5 can be manufactured with stainless steel or ceramic material, so just realize that connection sealing is good, high pressure resistant and structure Reliable technique effect.
