Abstract
The utility model discloses a compensable bidirectional sealed gate valve comprising a gate plate, fill material, a pressing cover, bolts, a multifunctional gate valve body, sealing valve seats, valve seat pressing plates, an O-shaped loop, and leaf springs. 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 sealing valve seats on both two sides. The valve seat pressing plates are disposed on the top of the sealing valve seats and the O-shaped loop is disposed between the valve seat pressing plates and the sealing valve seats. The leaf springs against the sealing valve seats are disposed under the valve seat pressing plates. The filling material is disposed in the stuffing box equipped with the pressing cover on the top of the stuffing box. The compensable bidirectional sealed gate valve achieves compensation for the wear of the sealing face and increases utilization ratio of the sealing valve seats.
Description
Technical field
The utility model relates to valve technology field, but particularly a kind of compensate for bidirectional 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, and body cavity is narrow and small, and this makes the casting technique difficulty very big, seals the disconnecting link valve firmly in use in the past, and sealing surface is wearing and tearing constantly, and sealing surface wear is bad to be scrapped.Sealing surface does not have the sealing wear compensability.
The model utility content
In order to overcome the defective that above-mentioned existing technology exists; But the utility model provides a kind of compensate for bidirectional sealing disconnecting link valve; The compensable disconnecting link valve of sealing surface wear so not only fully improved the utilization ratio of seal valve seat, and valve also is improved greatly working life.
To achieve these goals, the technological scheme of the utility model is following:
But a kind of compensate for bidirectional sealing disconnecting link valve comprises flashboard, filler, gland, bolt, utility knife gate valve body, seal valve seat, disc holder, o type circle, spring sheet, 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, the flashboard both sides are equipped with seal valve seat, seal valve seat, and said seal valve seat top is provided with disc holder; Be provided with o type circle between disc holder and the seal valve seat; Be provided with the spring sheet that pushes up mutually with seal valve seat under the said disc holder, 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, in the using process, sealing surface is wearing and tearing constantly, and spring sheet is then realized the compensation of sealing surface wear, has not only improved the utilization ratio of seal valve seat, also prolonged valve working life.
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 valve body 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, the valve seat mounting base, 14, flashboard; 16, filler, 17, gland, 18, bolt, 21, seal valve seat; 51, disc holder, 52, seal valve seat, 53,0 type circle, 54, spring sheet.
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, but a kind of compensate for bidirectional sealing disconnecting link valve comprises flashboard 14, filler 16, gland 17, bolt 18, utility knife gate valve body 11, seal valve seat 21, disc holder 51,0 type circle 53, spring sheet 54; 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 both sides are equipped with seal valve seat 21, seal valve seat 52, and said seal valve seat top is provided with disc holder 51; Be provided with o type circle between disc holder 51 and the seal valve seat, stop medium to leak outside, be provided with spring sheet 54 under the said disc holder; Spring sheet pushes up with seal valve seat mutually, is provided with filler 16 in valve body 11 stuffing boxes 2, and 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; Latus rectum does not have groove, makes valve not block up slag, has 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; Two seal valve seats receive the elastic reaction of spring sheet to make it to be adjacent to all the time flashboard, and flashboard moves down up to flashboard and covers two sealing surfaces fully, and this moment, valve was 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.
