Description
Technical field
The present invention relates to valve technology field, particularly a kind of two way sealed 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, and body cavity is narrow and small, and this makes the casting technique difficulty very big; Particularly through the product of smart casting cere casting, if lumen is narrow and small, then stifled easily slag subsides; And be not easy casting; Cause product rejection, do not have the narrower and small and casting of the seal groove of groove two way sealed structure usually and require smoothly indeformablely, need sand to cast type technology and realize; Yet the valve of cast steel and stainless steel needs the cere essence to cast, because the disconnecting link valve that the limitation of casting technique makes integrated type not have groove structure is difficult to realize through essence casting casting.
The model utility content
In order to overcome the defective that above-mentioned existing technology exists, the utility model provides a kind of two way sealed disconnecting link valve, and the valve casting is easy, and success rate is high, and valve seat is replaceable, improves the serviceability of valve, and valve can repeatedly use, and sealing can reach zero leakage.
To achieve these goals, the technological scheme of the utility model is following:
A kind of two way sealed disconnecting link valve comprises flashboard, filler, gland, bolt, utility knife gate valve body, movable sealing valve seat, elastic sealing strip, 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 said valve body body cavity, the flashboard both sides are equipped with the movable sealing valve seat, in the valve seal bar mounting groove elastic sealing strip are housed; 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 that the valve body body cavity does not have complicated turning greatly, this feasible casting easily; Be not easy stifled sand, the bottom does not have groove structure makes the valve bottom not block up slag, and casting surface is bright and clean; Casting success ratio is high; Valve seat is replaceable, realizes that valve utilizes again, has prolonged the working life of valve greatly.
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, 12, the movable sealing valve seat, 13, elastic sealing strip, 14, flashboard; 15, movable sealing valve seat, 16, filler, 17, gland, 18, bolt.
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; A kind of two way sealed disconnecting link valve comprises flashboard 14, filler 16, gland 17, bolt 18, utility knife gate valve body 11, movable sealing valve seat 12, elastic sealing strip 13, and 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; Said stuffing box 2 both sides are provided with support connecting base 1; Stuffing box 2, body cavity 5, flanged surface 4 connect successively, are provided with Stamping Steel Ribbon mounting groove 6 around the body cavity 5, and flanged surface 4 upper ends are provided with flange bolt silk hole boss 3; 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 both sides are equipped with movable sealing valve seat 12 and movable sealing valve seat 15, in the valve body 11 Stamping Steel Ribbon mounting grooves 6 elastic sealing strip 13 are housed; 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; 13 inner sealings of realizing valve body 11 of elastic sealing strip, body cavity 5 is a straight space body cavity, latus rectum does not have groove; Make valve not block up slag, simplified the valve manufacturing process.Operate the rotation of handwheel drive valve rod and makes Stem Mut drive flashboard do stroke action up and down, when pressing close to Stamping Steel Ribbon fully bottom flashboard closes to flashboard, valve is in buttoned-up status and plays seal action, and sealing can reach zero leakage; Break away from all-pass when footpath fully when flashboard rises to, valve is in the complete opening state.
