Abstract
The utility model provides a short type plate valve, is including flashboard, the valve body in no water conservancy diversion hole, the valve body both sides respectively are equipped with the transverse plane, be equipped with the screw thread blind hole that is used for with the pipe connection on the transverse plane valve body upper portion is equipped with connecting portion, the one end of connecting portion is connected on the valve body, the other end of connecting portion is equipped with the flange, the bottom surface of flange with valve body surface's vertical height is less than 0.5cm, the flange is equipped with the screw hole that is used for with valve cover connection. Compare the plate valve in prior art, the utility model has the advantages of simple structure, easy processing, the gate valve contraction in length, high reduction has reduced the requirement of gate valve to installation space. Because the self sealss characteristic of O type circle 11, including the pretightning force that provides of spring 10, under low pressure, vacuous operating mode, the leakproofness is better than ordinary plate valve.
Description
Technical field
The utility model relates to plate valve field, particularly relates to a kind of short plate valve.
Background technique
Gate valve is as a kind of valve of pilot line break-make, because the advantage such as flow resistance is little, good seal performance, is widely used in every field.Now commercially using maximum is plate valve, common plate valve requires all higher to the processing and assembling of sealing surface, and the size of existing plate valve length and height is larger, take installing space comparatively large, be not suitable for the place of the limited spaces such as tank farm, Manifolds, junction, harbour and drill platform.
Model utility content
In order to overcome the defect of prior art, the utility model provides following technological scheme:
A kind of short plate valve, comprise flashboard, the valve body without pod apertures, described valve body both sides are respectively provided with Transverse plane, described Transverse plane is provided with the tapped blind hole for being connected with pipeline, be provided with joint on described valve body top, one end of described joint is connected on described valve body, and the other end of described joint is provided with flange, the bottom surface of described flange and the vertical height of described valve body surface are less than 0.5cm, and described flange is provided with the tapped hole for being connected with valve gap.
Further, also comprise two valve seats, described valve seat is cylindrical-shaped structure, described two valve seats are symmetrical arranged in described valve inner, one bottom surface of described valve seat coordinates with described valve body, matches with described flashboard in another bottom surface of described valve seat, matches with described valve body in the side of described valve seat.Further, between a bottom surface of described valve seat and described valve body, be provided with spring, between another bottom surface of described valve seat and described flashboard, be provided with O type circle, between the side of described valve seat and described valve body, be provided with O type circle.Further, a bottom surface of described valve seat is provided with receiving bore, is provided with spring in described receiving bore, the bottom connection place of described spring one end and described receiving bore, and the other end of described spring contacts with described valve body.
Compared to plate valve of the prior art, the beneficial effects of the utility model are:
1, structure of the present utility model is simple, easily processes, gate valve shorten length, height reduction, reduces the requirement of gate valve to installing space;
2, because the self-sealing characteristics of O type circle 11, add the pretightening force that upper spring 10 provides, under the operating mode of low pressure, vacuum, sealing is better than common plate valve.
Accompanying drawing explanation
Hereinafter describe specific embodiments more of the present utility model with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference character identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:
Fig. 1 is general structure schematic diagram of the present utility model;
Fig. 2 is the enlarged partial sectional view of the utility model valve seat.
Embodiment
Short plate valve as shown in Figure 1, comprise the flashboard 1 without pod apertures, valve body 3, described valve body 3 both sides are respectively provided with Transverse plane 4, described Transverse plane 4 is provided with the tapped blind hole 5 for being connected with pipeline, the Transverse plane 4 of described pipeline and described valve body is combined together by the mode of monolateral nut screwing clamping, therefore the length of gate valve is greatly reduced, joint 6 is provided with on described valve body 3 top, one end of described joint 6 is connected on described valve body 3, the other end of described joint 6 is provided with flange 7, the bottom surface of described flange 7 and the vertical height on described valve body 3 surface are less than 0.5cm, described flange 7 is provided with the tapped hole 8 for being connected with valve gap, described valve gap and described flange 7 are combined together by the mode of monolateral nut screwing clamping, therefore the height of gate valve is reduced to a certain extent.
Preferably, also comprise two valve seats 2, described valve seat 2 is cylindrical-shaped structure, described two valve seats 2 are arranged in described valve body 3 internal symmetry, one bottom surface of described valve seat coordinates with described valve body 3, matching with described flashboard 1 in another bottom surface of described valve seat, matches with described valve body 3 in the side of described valve seat.
Preferably, between a bottom surface of described valve seat and described valve body, be provided with spring 10, between another bottom surface of described valve seat and described flashboard 1, be provided with O type circle 11, between the side of described valve seat and described valve body 3, be provided with O type circle 11.Because the self-sealing characteristics of O type circle 11, adds the pretightening force that upper spring 10 provides, under the operating mode of low pressure, vacuum, sealing is better than common plate valve.
Preferably, a bottom surface of described valve seat is provided with receiving bore 9, is provided with spring 10 in described receiving bore 0, the bottom connection place of described spring 10 one end and described receiving bore 9, and the other end of described spring 10 contacts with described valve body 3.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
