Description
Technical field
The utility model relates to a kind of gate valve, refers in particular to a kind of convenient filtration and the gate-valve device of good airproof performance.
Background technique
Gate valve is widely used a kind of valve in pipe network system, is also often referred to as gate valve or gate valve.In gate valve, drive closure member (i.e. flap) along moving with the direction of valve seat central axis the media flow cut off and open in pipeline by valve rod.Gate valve is usually applicable to keep flap standard-sized sheet or full cut-off and does not need the operating mode that often opens and closes.The feature of gate valve is: standard-sized sheet fluid resistance is little; Open and close laborsaving; Can use when medium two-way flow, there is no directivity; During standard-sized sheet, sealing surface is not vulnerable to erosion; Structure length is short, is not only applicable to doing the little valve of size, and is applicable to doing the large valve of size.
For gate valve, sealability always is one of tradition reference evaluating gate valve quality, how to allow whole gate-valve device have place that preferably sealability is our hammer away always, in addition, due to people's getting more and more to the multi-functional pursuit of a product, so how allowing product have additional function is also think deeply part as us, such as how increasing strainability to gate valve is then one of them, generally speaking, strainability is generally realized by the independent mode increasing a filter assemblies, like this then there is troublesome poeration and the higher defect of cost.
In view of this, the applicant furthers investigate for above-mentioned defect, then has this case to produce.
Model utility content
The purpose of this utility model is to provide a kind of convenient filtration and the gate-valve device of good airproof performance, and it without the need to independently arranging a set of filtration, and has effect of good airproof performance simultaneously.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of convenience is filtered and the gate-valve device of good airproof performance, comprise valve body, valve gap, valve rod, valve pad and filter bag, this valve gap and valve body are fixedly linked, this valve rod drives valve pad to move up and down to open or the fluid passage of checking-valve body, wherein, these valve pad both sides are provided with the seal face of V-shaped, this valve body is formed with the sealing seat coordinated with valve pad seal face, sealing seat has the second surface that the first surface identical with V-shaped seal face gradient and gradient are less than V-shaped seal face, this first surface is positioned at upper end, fluid passage, this second surface is positioned at lower end, fluid passage, also be formed with inner groove bottom this valve pad, this filter bag one end is connected with bottom inner groove, and the other end is connected to the bottom of fluid passage.
Further, this valve body is also provided with sealing gasket in the bottom at valve pad place, and the other end of this filter bag is connected on sealing gasket.
Further, this gate-valve device also comprises some springs, and each both ends of the spring is resisted against sealing gasket and duct bottom respectively, and sealing pad is upspring when gate-valve device is in opening state and is in same surface with valve body fluid vias inner walls under the effect of some springs.
Further, between this first surface and second surface, be formed with α angle, 5 degree of < α <15 degree.
After adopting said structure, the gate-valve device that the utility model relates to, sealing seat is by being provided with first surface and second surface, and allow the gradient of first surface be greater than the gradient of second surface, so when valve pad coordinates with second surface, valve pad can be allowed to produce certain compressive strain, improve the sealability of whole gate valve.
In addition, the utility model by forming inner groove bottom valve pad, then is connected with filter bag bottom inner groove, and so when gate-valve device is in opening state, this filter bag can be extended state, and then plays the effect of filtering fluid in passage.
Compared with prior art, the utility model not only has the good feature of sealability, but also can play the effect that convection cell carries out filtering simultaneously, has the market competitiveness.

Embodiment
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of convenience that the utility model relates to is filtered and the gate-valve device of good airproof performance, comprise valve body 1, valve gap 2, valve rod 3, valve pad 4 and filter bag 5, this valve gap 2 and valve body 1 are fixedly linked, and this valve rod 3 drives valve pad 4 to move up and down to open or the fluid passage 11 of checking-valve body 1.
These valve pad 4 both sides are provided with the seal face 41 of V-shaped, this valve body 1 is formed with the sealing seat coordinated with valve pad 4 seal face 41, sealing seat has the second surface 13 that the first surface 12 identical with V-shaped seal face 41 gradient and gradient are less than V-shaped seal face 41, this first surface 12 is positioned at upper end, fluid passage 11, and this second surface 13 is positioned at lower end, fluid passage 11; Also be formed with inner groove 42 bottom this valve pad 4, this filter bag 5 one end is connected with bottom inner groove 42, and the other end is connected to the bottom of fluid passage 11.
Preferably, be formed with α angle between this first surface 12 and second surface 13,5 degree of < α <15 degree, so can allow while having better sealing and also have good operability concurrently.
Like this, the gate-valve device that the utility model relates to, sealing seat is by being provided with first surface 12 and second surface 13, and allow the gradient of first surface 12 be greater than the gradient of second surface 13, so when valve pad 4 coordinates with second surface 13, valve pad 4 can be allowed to produce certain compressive strain, improve the sealability of whole gate valve.In addition, the utility model by forming inner groove 42 bottom valve pad 4, then is connected with filter bag 5, so when gate-valve device is in opening state bottom inner groove 42, this filter bag 5 can be extended state, and then plays the effect of filtering fluid in passage.
Preferably, in order to improve the sealability of gate-valve device, this valve body 1 is also provided with sealing gasket 6 in the bottom at valve pad 4 place, and the other end of this filter bag 5 is connected on sealing gasket 6.As depicted in figs. 1 and 2, in the present embodiment, sealing pad 6, once installation, is just fixed on bottom.
As shown in Figure 3 and Figure 4, as preferred embodiment, this gate-valve device also comprises some springs 7, each spring 7 two ends is resisted against sealing gasket 6 and duct bottom respectively, and sealing pad 6 is upspring when gate-valve device is in opening state and is in same surface with valve body 1 fluid passage 11 inwall under the effect of some springs 7.So, when gate-valve device is in opening state, sealing pad 6 can be upspring under equilibrium of forces, so makes whole fluid passage 11 be always a plane, largely avoided the possibility of impurity alluvial in fluid passage 11 like this, improves the quality of whole gate valve.
Above-described embodiment and accompanying drawing non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
