Abstract
The utility model discloses a bidirectional sealed high-temperature-resistant gate valve comprising a gate plate, filling material, a pressing cover, blots, a multifunctional gate valve body, a metal sealing strip, metal valve seats, and a sealing ring. 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 metal valve seats on both two sides. The metal sealing strip is disposed in the sealing strip mounting groove and the sealing ring is disposed on the bottom of the metal sealing strip. The filling material is disposed in the stuffing box equipped with the pressing cover on the top of the stuffing box. The bidirectional sealed high-temperature-resistant gate valve has a characteristic of high temperature resistance. The valve seat, which employs wear-resistant material so as to make the valve wear resistant, is replaceable in order to prolong the service life of the valve.
Description
Technical field
The utility model relates to valve technology field, the high temperature resistant disconnecting link valve of particularly a kind of two way sealed.
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; And those hard sealing two-way sealing disconnecting link valves all were the fluted structures in bottom in the past; Easily stifled slag and not being durable, in the reality, some pipeline need be installed high temperature resistant; The easy disconnecting link valve of deslagging again, existing technology is difficult to meet the need of market.
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 high temperature resistant disconnecting link valve,
To achieve these goals, the technological scheme of the utility model is following:
A kind of two way sealed is high temperature resistant disconnecting link valve comprises flashboard, filler, gland, bolt, utility knife gate valve body, metallic seal bar, metal seat valve, seal ring, 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, and stuffing box, body cavity, flanged surface connect successively, are provided with the Stamping Steel Ribbon mounting groove around the body cavity; The flanged surface upper end is provided with flange bolt silk hole boss, and the lower end is provided with the valve seat mounting base, is provided with flashboard in the valve body body cavity; The flashboard both sides are equipped with metal seat valve, metal seat valve, realize high temperature resistantly, in the valve seal bar mounting groove metallic seal bar are housed; Metallic seal bar bottom is provided with seal ring, guarantees the sealing effect of Stamping Steel Ribbon bottom, is provided with filler in the valve body stuffing box; The stuffing box upper end is provided with gland; Through the turn-knob bolt, gland is compressed filler be close to flashboard, realize the last seal action of disconnecting link valve.
The said body cavity of the utility model is a straight space body cavity.
The beneficial effect of the utility model is, the straight no groove in all-pass footpath makes the stifled slag of valve, and has high-temperature stability, and valve seat adopts high-abrasive material to make valve have more wear resistance, and simultaneously, valve seat is replaceable, makes life of valve long more durable.
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, the valve seat mounting base; 14, flashboard, 16, filler, 17, gland, 18, bolt; 41, metallic seal bar, 42, metal seat valve, 43, metal seat valve, 44, seal ring.
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 is high temperature resistant disconnecting link valve comprises flashboard 14, filler 16, gland 17, bolt 18, utility knife gate valve body 11, metallic seal bar 41, metal seat valve 42, seal ring 44; 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 metal seat valve 42, metal seat valve 43, in the valve body 11 Stamping Steel Ribbon mounting grooves 6 metallic seal bar 41 are housed; Metallic seal bar 41 bottoms are provided with seal ring 44, are 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 valve rod and rotates and makes Stem Mut drive flashboard to do stroke action up and down, and when flashboard cut out, the flashboard edge that keeps to the side closely was adjacent to sealing with the metallic seal valve seat, is adjacent to sealing surface fully up to the flashboard bottom, 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.
