Abstract
The utility model discloses a kind of rolling and open and close cross flow check valve, comprise valve body, be arranged on the endoceliac flap of valve and valve rod, the sealing surface of described flap and valve body entrance point is adaptive, it is characterized in that: be provided with front support near flap position in valve body chamber, be provided with rolling bearing in the middle part of front support; Also be threaded in described valve body chamber the support of coaxial line, and be provided with rear support in support, rear support is provided with rolling bearing.The utility model is adopted to efficiently solve the use problem of safety check in low pressure operating mode.
Description
Technical field
The utility model relates to valve field, and specifically a kind of rolling opens and closes cross flow check valve.
Background technique
Existing general check valve, due to structural limitations, often needs when valve opening and closing large hoisting capacity to realize, causes pressure loss in piping excessive, and waste is serious, and not energy-conservation, the operating mode very low in ask for something cracking pressure cannot use especially.
Model utility content
The utility model aims to provide a kind of rolling and opens and closes cross flow check valve, and open to realize minute-pressure, the pressure loss is very little, valve will be caused normally to use because pipeline operation pressure is low.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of rolling opens and closes cross flow check valve, comprise valve body, be arranged on the endoceliac flap of valve and valve rod, the sealing surface of described flap and valve body entrance point is adaptive, it is characterized in that: be provided with front support near flap position in valve body chamber, be provided with rolling bearing in the middle part of front support; Also be threaded in described valve body chamber the support of coaxial line, and be provided with rear support in support, rear support is provided with rolling bearing.
Further, described flap is provided with front support rod, and front support rod is through the rolling bearing in front support.
Further, described valve rod one end with between flap with and wire ring be connected, the valve rod the other end is slidably connected in the rolling bearing of support rear support.
Further, be also provided with Returnning spring between described flap and support, spring housing is on valve rod.
The beneficial effects of the utility model are: linkage structure is simple, safe and practical.Have employed rolling type opening/shutting mode, more generally slip keying type safety check, hoisting capacity can reduce a lot.And the elastic force of return spring can reduce a lot, decreases the Pressure Drop caused because spring force is excessive.It is very low that this kind of valve is specially adapted to certain operations pressure, and the low system of requirement falls in loine pressure.
Accompanying drawing explanation
Fig. 1 is that the rolling that the utility model provides opens and closes cross flow check valve structural representation.
Mark in figure: 1 be valve body, 2 be flap, 3 be valve rod, 4 be support, 5 be rear support, 6 be front support, 7 be rolling bearing, 8 for spring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of rolling opens and closes cross flow check valve, comprise valve body 1, be arranged on flap 2 in valve body 1 chamber and valve rod 3, described flap 2 is adaptive with the sealing surface of valve body 3 entrance point, it is characterized in that: be provided with front support 6 near flap 2 position in valve body 3 chamber, in the middle part of front support 6, be provided with rolling bearing 7; Also be threaded in described valve body 1 chamber the support 4 of coaxial line, and be provided with rear support 5 in support 4, rear support 5 is provided with rolling bearing 7.Described flap 2 is provided with front support rod, and front support rod is through the rolling bearing 7 in front support 6.Described valve rod 3 one end with between flap 2 with and wire ring be connected, valve rod 3 the other end is slidably connected in the rolling bearing 7 of support 4 rear support 6.Also be provided with Returnning spring 8 between described flap 2 and support 4, spring 8 is enclosed within valve rod 3.
When rolling provided by the utility model opens and closes, a distinguishing feature of cross flow check valve is: the front support rod on flap 2, valve rod 3, be installed among rolling bearing, valve is when opening or close, it is force of rolling friction that valve rod moves produced frictional force, very little, is applicable to the process pipeline of low engaging pressure operating mode.When medium applies a pressure by valve body 1 inlet end to morbidity 2, flap 2 meeting moving linearly to the right, valve opening, medium is entered into by valve body 1 and sends out a rear pipeline.When pressure medium reduces, upstream pressure and downstream pressure tend to balance gradually, and flap 2 under the effect of spring 4, can promote flap 2 and be moved to the left, until valve closing.And in the motion that this both direction of valve opening and closedown is contrary, valve rod 3, what all produce between flap front support and bearing is rolling friction.Resistance to motion is little, therefore can realize micro-pressure unlatching or close.The utility model is adopted to efficiently solve the use problem of safety check in low pressure operating mode.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
