Abstract
The utility model discloses a novel flexibly sealed gate valve with a residue extraction hole. An inlet hole of a valve body is plane sealed by a unilaterally collar seal which is made of politef composite material, and the operating force moment is short. The vertical surface of a flash-board is tightly connected with the collar seal surface which is pressed into a ring slot of the valve body through the action of the unilaterally oblique plane of the flash-board and the oblique plane of the corresponding valve body, which avoids the abrasion and prolongs the service life. The upper collar seal is made of the composite material of fluorine and carbite, the agent leakage phenomenon is expelled without changing the upper collar seal. The outlet end of the valve body is opened with the cuneate residue extraction hole, which employs the design that the resistance of the residue flowing is avoided because that no steep-shaped protrusion is formed from the bottom portion of the valve body to an exit flange, so the impurity deposition phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of gate valve, especially refers to a kind of novel gate valve that the slag exhausting mouth soft seal is arranged.
Background technique
The sealing of tradition gate valve is to rely on the inversion inclined-plane of flashboard and closely cooperating of valve inner inclined-plane to reach (the hard sealing of saying usually), owing to flashboard and valve body all adopt metallic material, reaches that to close required pressure big.The key groove in the valve body and the key groove of flashboard require fitted seal precision height, and owing to the mutual extrusion between flashboard and valve body sealing surface, scratch easily, wearing and tearing can't seal fully during keying, cause leaking.Last seal ring adopts base root filler, and permanent the use can be hardened, and easily produces medium and leaks, and must often change base root filler.Owing to be provided with groove at valve body inner bottom part center, contamination precipitation appears easily, and cause and can't close, only be 6～12 months working life.
Summary of the invention
The purpose of this utility model is to provide a kind of novel gate valve, and its operational torque is little, do not wear and tear, do not leak, and contamination precipitation, long service life can not occur.
In order to achieve the above object, the utility model is realized by following technological scheme.
A kind of novel gate valve, comprise valve body, ptfe composite seal ring, flashboard, valve rod, pad, valve gap support, Packing seat, go up seal ring, gland, Stem Mut, handwheel, round nut, it is characterized in that: adopt planar design and be processed into annular groove at the valve inner entrance point, be pressed into the ptfe composite seal ring then, the outlet end of valve body adopts the inclined-plane and is provided with the wedge shape slag exhausting mouth; Flashboard simultaneously adopts the vertical plane design, and another side adopts inclined design; Valve rod is applied in Stem Mut, gland, goes up in the middle of seal ring, the Packing seat and connect flashboard and go deep into valve inner, at valve body and the middle pad that is provided with of being connected of valve gap support, be provided with successively on the valve gap support Packing seat, on seal ring, gland, be provided with handwheel, round nut at Stem Mut;
The one-sided inclined-plane of described flashboard matches with the one-sided inclined-plane of valve body;
The described flashboard vertical plane ptfe composite seal ring interior with being pressed into valve inner entrance point annular groove matches, and forms plane sealing;
The described seal ring of going up adopts fluorine, graphite composite material and Packing seat, gland to form combination and be located on the valve gap support, and lock by bolt;
The beneficial effects of the utility model are, adopt one-sided ptfe composite seal ring plane sealing at the valve inner entrance point, and operational torque is little.Because the one-sided inclined-plane of flashboard and the effect on corresponding valve body inclined-plane promote flashboard and are combined closely in its vertical plane and the seal ring plane that is pressed in the valve body annular groove, so wearing and tearing, long service life can not occur.Last seal ring adopts fluorine, graphite composite material, needn't change and then can get rid of the medium phenomenon that leaks.The outlet end of valve body has the wedge shape slag exhausting mouth, makes valve body form the design of no steep shape projection stream slag resistance from the bottom to the outlet(discharge) flange, the contamination precipitation phenomenon can not occur, and can reach more than 3 years working life.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is further elaborated.With reference to a kind of novel gate valve shown in the accompanying drawing 1, comprise valve body 1, ptfe composite seal ring 2, flashboard 3, valve rod 4, pad 5, valve gap support 8, Packing seat 9, go up seal ring 10, gland 12, Stem Mut 13, handwheel 14, round nut 16.Be processed into annular groove and be pressed into ptfe composite seal ring 2 at 1 inner entrance point vertical plane place at valve body, and the outlet end of valve body 1 has the wedge shape slag exhausting mouth, makes valve body 1 form the design of no steep shape projection stream slag resistance from the bottom to the outlet(discharge) flange.Be provided with successively on the valve gap support 8 Packing seat 9, on seal ring 10, gland 12, Stem Mut 13, Stem Mut 13 is provided with flat key 15; Gland 12 is fixed on the valve gap support 8 by bolt 11; Valve rod 4 is applied in the centre of Stem Mut 13, gland 12, last seal ring 10, Packing seat 9, connects flashboard 3.Be provided with handwheel 14, round nut 16 at Stem Mut 13, handwheel 14 is fixed on valve gap support 8 tops by flat key 15, round nut 16; Joint at valve body 1 and valve gap support 8 is provided with pad 5, and valve body 1 is locked by bolt 6, nut 7 with valve gap support 8.Rotation hand wheel 14 drives flashboard 3 by valve rod 4 and enters valve body 1 inside, because flashboard 3 is inverted inclined-plane and the effect on valve body 1 one-sided inclined-plane accordingly, promote the vertical plane of flashboard 3 and the ptfe composite seal ring 2 in valve body 1 groove and closely cooperate, form plane sealing.
Claims (3)
1, a kind of novel gate valve, comprise valve body, ptfe composite seal ring, flashboard, valve rod, pad, valve gap support, Packing seat, go up seal ring, gland, Stem Mut, handwheel, round nut, it is characterized in that: adopt the vertical plane Seal Design at the valve inner entrance point, process an annular groove at the vertical plane place, be pressed into the ptfe composite seal ring then, the outlet end of valve body adopts the inclined-plane and the design of wedge shape slag exhausting mouth is arranged; Flashboard simultaneously adopts the vertical plane design, and another side adopts inclined design; Valve rod is applied in Stem Mut, gland, goes up in the middle of seal ring, the Packing seat and connect flashboard and go deep into valve inner, at valve body and the middle pad that is provided with of being connected of valve gap support, be provided with successively on the valve gap support Packing seat, on seal ring, gland, be provided with handwheel, round nut at Stem Mut.
