Abstract
A short type flat gate valve comprises a gate plate without a flow guiding hole and a valve body; the two sides of the valve body are each provided with an end plane which is provided with a threaded blind hole used for being connected with a pipeline; a connection part is arranged on the upper portion of the valve body; one end of the connection part is connected to the valve body; a flange is arranged at the other end of the connection part; the perpendicular height of the bottom face of the flange and the surface of the valve body is smaller than 0.5 cm; and the flange is provided with a threaded hole used for being connected with a valve deck. Compared with a flat gate valve in the prior art, the short type flat gate valve is simple in structure and easy to machine, the length of the gate valve is reduced, the height is reduced, and the requirement of the gate valve for the installing space is lowered. Because of the self-sealing characteristic of an O-shaped ring 11 and the pre-tightening force provided by a spring 10, the sealing performance of the short type flat gate valve is better than that of a common flat gate valve under the low pressure and vacuum work condition.
Description
Technical field
The present invention relates to flat gate valve field, more particularly to a kind of short flat gate valve.
Background technology
Gate valve is widely used in every field as a kind of valve of control piper break-make because flow resistance is little, the advantages of good seal performance.Currently on the market using it is most be flat gate valve, common flat gate valve requires all higher to the process and assemble of sealing surface, and the size of existing flat gate valve length and height is than larger, take installing space larger, where not being suitable for the limited spaces such as tank farm, collecting tubule, junction, harbour and drilling platforms.
The content of the invention
In order to overcome the defect of prior art, the present invention to provide technical scheme below：
A kind of short flat gate valve, including the flashboard without pod apertures, valve body, the valve body both sides are respectively provided with transverse plane, the transverse plane is provided with the tapped blind hole for being connected with pipeline, connecting portion is provided with the valve body top, one end of the connecting portion is connected on the valve body, and the other end of the connecting portion is provided with flange, the bottom surface of the flange is less than 0.5cm with the vertical height of the valve body surface, and the flange is provided with the screwed hole for being connected with valve gap.
Further, also including two valve seats, the valve seat is cylindrical-shaped structure, described two valve seats are symmetrical arranged in the valve inner, one bottom surface of the valve seat is coordinated with the valve body, and another bottom surface of the valve seat is engaged with the flashboard, and the side of the valve seat is engaged with the valve body.Further, spring is provided between a bottom surface of the valve seat and the valve body, O-ring is provided between another bottom surface of the valve seat and the flashboard, between the side of the valve seat and the valve body, O-ring is provided with.Further, a bottom surface of the valve seat is provided with receiving hole, is provided with spring in the receiving hole, and at the spring one end and the bottom connection of the receiving hole, the other end of the spring is contacted with the valve body.
Compared to flat gate valve of the prior art, beneficial effects of the present invention are：
1st, simple structure of the invention, is easily worked, gate valve contraction in length, height reduction, reduces requirement of the gate valve to installing space；
2nd, because the self-sealing characteristics of O-ring 11, the pretightning force of the offer of spring 10 is added, under low pressure, the operating mode of vacuum, sealing is more preferable than common flat gate valve.
Description of the drawings
Describe some specific embodiments of the present invention hereinafter with reference to the accompanying drawings by way of example, and not by way of limitation in detail.In accompanying drawing, identical reference denotes same or similar part or part.It should be appreciated by those skilled in the art that what these accompanying drawings were not necessarily drawn to scale.In accompanying drawing：
Fig. 1 is the general structure schematic diagram of the present invention；
Fig. 2 is the enlarged partial sectional view of valve seat of the present invention.
Specific embodiment
Short flat gate valve as shown in Figure 1, including the flashboard 1 without pod apertures, valve body 3, 3 both sides of the valve body are respectively provided with transverse plane 4, the transverse plane 4 is provided with the tapped blind hole 5 for being connected with pipeline, the pipeline is combined together by way of monolateral nut screwing clamping with the transverse plane 4 of the valve body, therefore greatly reduce the length of gate valve, connecting portion 6 is provided with 3 top of the valve body, one end of the connecting portion 6 is connected on the valve body 3, the other end of the connecting portion 6 is provided with flange 7, the bottom surface of the flange 7 is less than 0.5cm with the vertical height on 3 surface of the valve body, the flange 7 is provided with the screwed hole 8 for being connected with valve gap, the valve gap is combined together by way of monolateral nut screwing clamping with the flange 7, therefore the height of gate valve is reduced to a certain extent.
Preferably, also include two valve seats 2, the valve seat 2 is cylindrical-shaped structure, described two valve seats 2 are arranged in 3 internal symmetry of the valve body, one bottom surface of the valve seat is coordinated with the valve body 3, another bottom surface of the valve seat is engaged with the flashboard 1, and the side of the valve seat is engaged with the valve body 3.
Preferably, spring 10 is provided between a bottom surface of the valve seat and the valve body, O-ring 11 is provided between another bottom surface of the valve seat and the flashboard 1, O-ring 11 between the side of the valve seat and the valve body 3, is provided with.Because the self-sealing characteristics of O-ring 11, the pretightning force of the offer of spring 10 is added, and under low pressure, the operating mode of vacuum, sealing is more preferable than common flat gate valve.
Preferably, a bottom surface of the valve seat is provided with receiving hole 9, is provided with spring 10 in the receiving hole 0, and at 10 one end of the spring and the bottom connection of the receiving hole 9, the other end of the spring 10 is contacted with the valve body 3.
So far, those skilled in the art will recognize that, although detailed herein illustrate and describe multiple exemplary embodiments of the invention, but, without departing from the spirit and scope of the present invention, many other variations or modifications for meeting the principle of the invention still can be directly determined or are derived according to present disclosure.Therefore, the scope of the present invention is understood that and regards as covering all these other variations or modifications.
