Abstract
The utility model discloses a unidirectional hard sealed gate valve comprising a gate plate, fill material, a pressing cover, bolts, a multifunctional gate valve body, a movable sealing valve seat, and wedges. The valve body comprises support connecting seats, a stuffing box, a flange bolt hole lug boss, a flange face, a body cavity, a sealing strip mounting groove, and a valve seat mounting base. The support connecting seats are disposed on both sides of the stuffing box, and the stuffing box, the body cavity, and the flange face are connected successively. The sealing strip mounting groove is disposed around the body cavity, and the flange bolt hole lug boss is disposed on the top of the flange face while the valve seat mounting base is disposed on the bottom of the flange face. The gate plate, which is disposed in the body cavity of the valve body, is equipped with the sealing valve seat on one side while overlaid with an upper wedge and a lower wedge on the other side. The filling material is disposed in the stuffing box equipped with the pressing cover on the top of the stuffing box. The bottom of the body cavity is flat so that slag is easy to remove. The movable valve seat can be made of material with higher hardness and wear resistance. The valve seat is replaceable so that the durability of the valve is improved, the cost of the valve is reduced, and the manufacturing technology of the valve is simplified.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of unidirectional hard sealing disconnecting link valve.
Background technique
The disconnecting link valve is claimed cutter door gate valve, cutter type Parallel Slide Valves again, and its using scope is very wide, and the coal separation of power plant, discharge refuse, deslagging from the mine are to the sewage treatment in city, from the general industrial pipeline to food, professional pipe-line systems such as health, medicine.The disconnecting link valve is little with its volume, flow resistance is little, in light weight, be prone to install, advantage such as quick detachable occupied the market leading position.
The characteristics of disconnecting link valve are that structure is slim; Body cavity is narrow and small; This makes the casting technique difficulty very big; The hard sealing structure of the disconnecting link valve of one-way sealing directly processed on valve body body valve seat in the past, and valve wearing and tearing at first in use is exactly seal valve seat, like this prooving of valve seat gone bad just to cause and put in order scrapping of deck valve door.This makes the valve user cost improve, and causes unnecessary fund waste.
The model utility content
In order to overcome the defective that above-mentioned existing technology exists, the utility model provides a kind of unidirectional hard sealing disconnecting link valve, makes valve seat replaceable, improves the serviceability of valve, and valve can repeatedly use, and has reduced the input spending of valve, and valve is deslagging more easily.
To achieve these goals, the technological scheme of the utility model is following:
A kind of unidirectional hard sealing disconnecting link valve comprises flashboard, filler, gland, bolt, utility knife gate valve body, movable sealing valve seat, carves piece, and said valve body comprises support connecting base, stuffing box, flange bolt silk hole boss, flanged surface, body cavity, Stamping Steel Ribbon mounting groove, valve seat mounting base; Said stuffing box both sides are provided with the support connecting base; Stuffing box, body cavity, flanged surface connect successively, are provided with the Stamping Steel Ribbon mounting groove around the body cavity, and the flanged surface upper end is provided with flange bolt silk hole boss; The lower end is provided with the valve seat mounting base; Be provided with flashboard in the valve body body cavity, flashboard one side is equipped with the movable sealing valve seat, and piece is carved in the opposite side built-up welding up and down; Be provided with filler in the valve body stuffing box, the stuffing box upper end is provided with gland.
The said body cavity of the utility model is a straight space body cavity.
The beneficial effect of the utility model is, piece is carved in built-up welding up and down, the convenient processing, and the latus rectum bottom is straight deslagging more easily, movable valve seat can be joined the bigger more wear-resisting material of hardness.Valve seat has convertibility, even valve seat damage so can not cause scrapping of whole deck valve door, as long as replacing activity valve seat just can re-use yet.On the very harsh sharp-pointed particle of those valve Environmental Conditions, the valve serviceability improves a lot, and can repeatedly use, and greatly reduces the input spending of valve, has simplified the valve manufacturing process.
Description of drawings
Fig. 1 is the utility model valve body structure schematic representation;
Fig. 2 is the structural representation of the utility model.
Among the figure, 11, the utility knife gate valve body, 1, the support connecting base, 2, stuffing box; 3, flange bolt silk hole boss, 4, flanged surface, 5, body cavity, 6, the Stamping Steel Ribbon mounting groove; 7, valve seat mounting base, 14, flashboard, 15, the movable sealing valve seat, 16, filler; 17, gland, 18, bolt, 31, carve piece.
Embodiment:
For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, unidirectional hard sealing disconnecting link valve comprises flashboard 14, filler 16, gland 17, bolt 18, utility knife gate valve body 11, movable sealing valve seat 15, carves piece 31; Said valve body 11 comprises support connecting base 1, stuffing box 2, flange bolt silk hole boss 3, flanged surface 4, body cavity 5, Stamping Steel Ribbon mounting groove 6, valve seat mounting base 7, and said stuffing box 2 both sides are provided with support connecting base 1, and stuffing box 2, body cavity 5, flanged surface 4 connect successively; Be provided with Stamping Steel Ribbon mounting groove 6 around the body cavity 5, flanged surface 4 upper ends are provided with flange bolt silk hole boss 3, and the lower end is provided with valve seat mounting base 7; Be provided with flashboard 14 in valve body 11 body cavitys 5, flashboard 14 1 sides are equipped with movable sealing valve seat 15, and piece 31 is carved in the opposite side built-up welding up and down; Be provided with filler 16 in valve body 11 stuffing boxes 2, stuffing box 2 upper ends are provided with gland 17, through turn-knob bolt 18; Gland 17 is compressed filler 16 be close to flashboard 14; Realize the last seal action of disconnecting link valve, body cavity 5 is a straight space body cavity, and latus rectum does not have groove; Make valve not block up slag, simplified the valve manufacturing process.The operation handwheel drives the valve rod rotation makes Stem Mut drive flashboard do stroke action up and down; When flashboard cuts out; The effect of pressing oblique thrust hard that the inclined-plane of flashboard bottom receives down to carve piece makes flashboard be close to sealing surface and covers sealing surface of seat fully up to flashboard that at this moment valve is in buttoned-up status; Break away from all-pass when footpath fully when flashboard rises to, valve is in the complete opening state.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
