Description
[technical field]
The utility model relates to a kind of spile type valve, belong to the corollary equipment on metallurgy industry or the gas pipeline, belong to valve field.
[background technique]
At present, two kinds basically on the structure of slotting metal plate formula valve, its basic structure all includes left and right sides valve body, gate frame and flashboard start-stop device, and described gate frame can move between the valve body of the left and right sides by the flashboard start-stop device, is provided with through hole circle and blind hole circle on the gate frame.The spile type valve has two kinds basically, and a kind of is the open type push-pull valve, and another kind is the slat belt push-pull valve.These push-pull valves generally all adopt a kind of power screw pair to come distance between the valve body of the harmomegathus left and right sides, when this power screw pair clamps left and right sides valve body, reach the purpose of sealing, during spreading left and right sides valve body, when just strutting left and right sides valve body, the gate frame is moved between the valve body of the left and right sides and reach the purpose of valve opening, and between the valve body of the left and right sides, be provided with expansion bend.The general secondary cover harmomegathus device of forming of power screw that adopts four to eight pairs of open type push-pull valve, there is following shortcoming in this push-pull valve: 1) inboard of left and right sides valve body need be with a slip joint as Displacement system, and the slip joint leading portion of this side valve body is the position that needs most mechanical strength in the valve, the active force of the power screw pair of whole valve all acts on this place, and causing need very high mechanical strength; 2) valve body all adopts welded structure, and part be after processing when assembling permitted welding again, so valve may deformation effect integral valve door sealing performance when being welded; 3) this power screw pair is to adopt the secondary displacement of bolt and nut, and must form the chain synchronous purpose of a cover to four to eight secondary power screw pairs with pull bar or sprocket wheel, and the efficient of the transmission of pull bar or the chain band of sprocket wheel composition one circle is lower, and screw rod and nut are easy to produce kills phenomenon; 4) this power screw pair is provided with the position and must allows the position of throttle valve frame, thereby the active force of its power screw pair is distant from the position of action point of valve plate, this active force far away is easy to generate rigid deformation at valve plate when clamping for a long time, the clamping force of 4～6 place's clamping points is changed, and cause the sealing effect of valve.Another kind of slat belt push-pull valve is to adopt the secondary cover harmomegathus device of forming of three secondary power screw, and there is above-mentioned defective equally in this valve.Above-mentioned its harmomegathus device of these spile type valves all is arranged on the valve body, thereby the mechanical strength of its valve body is the guarantee of valve seal performance and operational safety, and the valve of above-mentioned these structures, after the mechanical strength of its valve body is restricted, just directly influenced the reliability of spile type valve seal performance and use.
[model utility content]
In view of the mechanical strength that has valve body in the background technique restricted and cause influencing the valve seal Performance And Reliability can deficiency, the technical problems to be solved in the utility model provides a kind of scientific structure, the blind-hole type push-pull valve of the unaffected and good seal performance of the mechanical strength of valve body.
In order to solve the problems of the technologies described above, the utility model takes following technological scheme to realize: a kind of blind-hole type push-pull valve, include left and right sides valve body, gate frame and flashboard start-stop device, described gate frame can move between the valve body of the left and right sides by the flashboard start-stop device, on the gate frame, be provided with through hole circle and blind hole circle, described through hole circle is made up of the first through hole valve plate and the second through hole valve plate, described blind hole circle is by the first blind hole valve plate and the second blind hole valve plate, it is characterized in that the described first through hole valve plate is connected by bellows with the second through hole valve plate, is equipped with the harmomegathus device that the distance between them is stretched between the described first through hole valve plate and the second through hole valve plate and between the first blind hole valve plate and the second blind hole valve plate.
In the utility model, be connected with bellows with the second through hole valve plate, change to carry and traditional move the purpose that reaches clamping or spreading, on sealability, increase by valve body at the first through hole valve plate of through hole circle; After between the valve plate of correspondence the harmomegathus device being set, its active force acts directly on the valve plate, promote the purpose that valve plate just can reach sealing and spreading, thereby the mechanical strength of its left and right sides valve body is just unrestricted, do not exist owing to the secondary phenomenon that causes the valve plate distortion of available technology adopting power screw yet, thereby improved the sealing effect of this valve and the reliability of use, this blind-hole type push-pull valve is specially adapted on the pipeline of coal gas or toxic gas, as the shut-off means of gas.
In the above-mentioned technological scheme, described harmomegathus device includes the first secondary bar, second secondary bar and the push rod, and the two sliding pair of an end of the described first secondary bar and the second secondary bar and the hinged formation of push rod, its other end connect with corresponding valve plate respectively.
The another kind of technological scheme of above-mentioned harmomegathus device is to include the first secondary bar, second secondary bar and the push rod, the described first secondary bar and the second secondary bar are provided with chute, the first secondary bar and the second secondary bar are connected to become the two sliding pair of trapezoid shaped by slide blocks, described slide blocks moves on the chute of the first secondary bar and the second secondary bar, described slide blocks is connected with push rod, and the described first secondary bar is connected with valve plate with the side of the second secondary bar near valve plate.
After the harmomegathus device adopts the moving auxiliary structure of above-mentioned two-track, when valve plate spreading and valve seal, make the active force of push rod also can make this pair sliding pair reach the purpose of mechanical self-latching point-blank, its unfailing performance is higher.
In each above-mentioned technological scheme, on institute's gate frame, be provided with the floating installation that makes through hole circle and blind hole circle harmomegathus; This floating installation includes upper saw pulley, the spacing adjusting screw of shrinking back and location positioning adjusting screw, and the described spacing adjusting screw of shrinking back is installed on the valve plate, and described location positioning adjusting screw is installed on the gate frame.
Adopt this floating installation, the position of through hole circle and blind hole circle is adjusted, it is floated, and can move it, distance in the time of can also adjusting through hole circle and blind hole circle and valve body sealing surface and shrink back, the through hole circle does not contact with the sealing surface of valve body with seal ring on the blind hole circle in the time of can guaranteeing to shrink back, to improve its reliability.
