Abstract
The invention discloses a low-consumption flat valve, comprising a valve which is internally provided with a valve cavity and a valve plate capable of moving upwards and downwards along the valve cavity to open or close the flat valve. The valve plate and the valve cavity are sealed by a valve seat; and a location-limiting device is installed below the valve plate and matched with the valve to locate the valve seat. The low-consumption flat valve is provided with a location-limiting block inside the valve below the valve plate, so that not only the stable location of the valve seat at the fixed position of the valve is ensured, but also the sealing performance of the flat valve is ensured. The flat valve of the invention has the advantages of simple structure, small volume and suitability of a plurality of installation conditions.
Description
Technical field
The present invention relates to the flap type that a kind of wellhead assembly, throttle kill manifold and oil and gas pipeline are used, the flap type that chemical industry, nuclear power are used.
Background technology
At present, the flap type that wellhead assembly, throttle kill manifold and oil and gas pipeline are used has to divide with flashboard two kinds of patterns: a kind of is flashboard band runner hole, as shown in Figure 1a; Another kind is not to be with the runner hole, shown in Fig. 1 b.Be arranged on the bottom of flap type valve plate 1 with the runner hole 11 of runner hole flap type, seal by valve seat 2 between valve plate 1 and the valve pocket 3, runner hole 11 and valve pocket 3 be not on same axis, valve plate 1 shutoff valve pocket 3, flap type cuts out, move to runner hole 11 and valve pocket 3 on the valve plate 1 when same axis, flap type is opened.Although the flap type of this kind form can guarantee the sealing performance of flap type, because it has lengthened the length of valve plate, cause the increase of flap type overall volume, cost to improve, carry inconvenience, are unfavorable for execute-in-place.
With the flap type in runner hole, because valve seat 2 ' is by the shell thrusting action of valve plate 1 ' with valve pocket 3 ' flap type to be sealed, be not subjected to the gap affects of valve pocket 3 ' and valve seat 2 ', the switch of flap type causes this structure flap type sealing performance unstable.
Summary of the invention
Problem for prior art exists the invention provides a kind of simple in structure, good seal performance, can be suitable for the flap type of multiple installation operating mode.
For achieving the above object, low-consumption flat valve of the present invention, comprise valve body, have valve pocket and the valve plate that can move up and down to open or seal along valve pocket flap type in the valve body, pass through valve base sealing between valve plate and the valve pocket, the below of described valve plate is provided with stopping means, cooperates described valve seat location by this stopping means and valve body.
Further, described stopping means is the cylindricality limited block, and limited block end face size matches with described valve plate size, guarantees that valve plate can set on limited block.
Further, described valve interior wall and valve plate are clamped in described valve seat between the two.
Further, described limited block is up-small and down-big structure, and limited block end face and described valve plate match, and described valve seat one end pushing tow is in described valve plate and limited block top one side, and the step that forms between the described limited block upper and lower part is positioned at below, described valve seat bottom surface.
Further, relative both sides, described limited block bottom have a tangent plane.
Low-consumption flat valve of the present invention is provided with limited block in the valve body of the bottom of valve plate, both guaranteed that valve seat can the permanent position of strong fix in valve body, has guaranteed again the sealing performance of flap type.Low-consumption flat valve of the present invention is simple in structure, volume is little, can adapt to multiple installation operating mode.

The specific embodiment
Shown in Fig. 2 and 3, low-consumption flat valve of the present invention, comprise valve body, have valve pocket 3 in the valve body " and can be along valve pocket 3 " move up and down to open or seal the valve plate 1 of flap type "; valve plate 1 " and valve pocket 3 " by valve seat 2 " sealing, valve plate 1 " the below be provided with stopping means 4, cooperate valve seat 2 by this stopping means 4 and valve body " location.
Shown in Fig. 4 a and Fig. 4 b, stopping means 4 is the cylindricality limited block, and limited block is engaged by top small column 41 and bottom big column 42 and forms, and the upper and lower joint portion of limited block has a step.Big column 42 relative both sides in bottom have tangent plane 421, can easily limited block be installed on the valve body bottom by this tangent plane 421.Limited block top small column 41 end faces and the valve plate directly over it 1 " size matches; valve plate 1 " thickness and limited block end face circular diameter equal and opposite in direction, only having enumerated limited block in the present embodiment is columniform situation, can be according to actual needs to valve plate 1 in the reality " shape and the shape Self-adjustment of limited block, only need to guarantee valve plate 1 " bottom surface and limited block end face size match and get final product.
As shown in Figure 3, limited block of the present invention is installed in the valve body, by valve plate 1 ", limited block 4 and valve interior wall acting in conjunction; with valve seat 2 " be positioned in the valve body, when flap type opens or closes, valve seat 2 " and valve plate 1 " apart from remaining constant, guaranteed the positiver sealing of flap type.In addition, because limited block is arranged to up-small and down-big structure, put upside down when installing if guaranteed flap type, by valve seat 2 " with the step effect under; can prevent that limited block 4 from dropping from valve body, when having guaranteed safety, the sealing of flap type, make flap type can satisfy plurality of installation forms.
It is to be noted and any distortion of having done according to the specific embodiment of the present invention all do not break away from the scope that spirit of the present invention and claim are put down in writing.
