Abstract
The utility model discloses a kind of steam valve, comprise valve casing, described valve casing left side is provided with steam inlet, bottom is provided with steam ouput, is provided with vaporium in valve casing, and valve rod that can knee-action is connected with spool through after valve casing, spool is positioned at vaporium and is positioned at steam ouput top, in described vaporium, be also fixedly installed pilot sleeve, described spool is movably arranged in pilot sleeve, and left side, the bottom surface of described pilot sleeve is low, right side is high.Above-mentioned steam valve, spool is located in pilot sleeve, and left side, the bottom surface of pilot sleeve is low, right side is high, the high velocity air of coming from steam inlet directly produces and impacts pilot sleeve, and the impact that spool is subject to is less, therefore can guarantee seal when valve turn-offs, the working life of guaranteeing spool.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of steam valve.
Background technique
Steam valve is applied comparatively extensively industrial, existing steam valve spool is directly exposed in vaporium, spool and air-flow area of contact are large, thereby the high velocity air that steam inlet comes enters to connect impact spool, make spool produce vibration, sealing while affecting steam valve shutoff, spool also easily damages, and affects the working life of steam valve.Therefore, be necessary above-mentioned steam valve to do technological improvement.
Summary of the invention
The purpose of this utility model is a kind of steam valve designing in order to solve the deficiency of above-mentioned technology, and this steam valve can prevent that spool is subject to greater impact.
A kind of steam valve that the utility model is designed, comprise valve casing, described valve casing left side is provided with steam inlet, bottom is provided with steam ouput, is provided with vaporium in valve casing, and valve rod that can knee-action is connected with spool through after valve casing, spool is positioned at vaporium and is positioned at steam ouput top, in described vaporium, be also fixedly installed pilot sleeve, described spool is movably arranged in pilot sleeve, and left side, the bottom surface of described pilot sleeve is low, right side is high.
Above-mentioned steam valve, spool is located in pilot sleeve, and left side, the bottom surface of pilot sleeve is low, right side is high, the high velocity air of coming from steam inlet directly produces and impacts pilot sleeve, and the impact that spool is subject to is less, therefore can guarantee seal when valve turn-offs, the working life of guaranteeing spool.
As such scheme, further improve, described spool is elastic caoutchouc, and valve core inside has cavity, and when opening and closing, cavity all can produce certain deformation, opens and closes and all has a phase buffer, can reduce impact and the vibration of steam valve inside.
Accompanying drawing explanation
Fig. 1 is wherein a kind of structural representation of mode of execution of the utility model;
Fig. 2 is wherein a kind of structural representation of pilot sleeve of the utility model;
Fig. 3 is the structural representation of the another kind of pilot sleeve of the utility model;
Fig. 4 is the structural representation of the another kind of mode of execution of the utility model;
In figure: valve casing 1, steam inlet 2, steam ouput 3, vaporium 4, valve rod 5, spool 6, pilot sleeve 7, cavity 8.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
The disclosed a kind of steam valve of Fig. 1, comprise valve casing 1, described valve casing 1 left side is provided with steam inlet 2, bottom is provided with steam ouput 3, in valve casing 1, be provided with vaporium 4, valve rod 5 that can knee-action is connected with spool 6 after through valve casing 1, valve rod 5 bottoms arrange outside thread, spool 6 end faces are provided with internal thread, both screw-thread fit form and connect, significantly, the Placement that also has other, as adopt fixing pin that both are fixed together, spool 6 is positioned at vaporium 4 and is positioned at steam ouput 3 tops, when driving spool 6 descending, valve rod 5 steam ouput 3 can be shut to the shutoff that realizes valve, in described vaporium 4, be also fixedly installed pilot sleeve 7, described spool 6 is movably arranged in pilot sleeve 7, so-called movable setting refers to that spool 6 and pilot sleeve 7 cooperatively interact and can move up and down, the left side, bottom surface of described pilot sleeve 7 is low, right side is high, pilot sleeve 7 its structures can be as shown in Figure 2, bottom surface is stepped, also can be as Fig. 3, bottom surface is transitional face to more gentle inclined plane shape, pilot sleeve 7 bottom surfaces, left side are minimum be can be made into and steam ouput 3 end contacts, steam completely divides and enters steam ouput 3 through pilot sleeve 7 right sides like this, also better to the protective action of spool 6.The material selection stainless steel of spool 6 or other resistant to elevated temperatures alloy materials.
Above-mentioned steam valve, spool 6 is located in pilot sleeve 7, the bottom surface left side of pilot sleeve 7 is low, right side is high, the high velocity air of coming from steam inlet 2 directly produces and impacts pilot sleeve 7, and the impact that spool 6 is subject to is less, therefore can guarantee seal when valve turn-offs, the working life of guaranteeing spool.
Fig. 2 discloses another kind of mode of execution of the present utility model, steam valve difference shown in itself and Fig. 1 is: described spool 6 is elastic caoutchouc, spool 7 inside have cavity 8, when opening and closing, cavity 8 all can produce certain deformation, open and close and all there is a phase buffer, can reduce impact and the vibration of steam valve inside.
Above-described embodiment is only to design of the present utility model explanation for example, and significantly, the protection domain of this patent is not limited to above-described embodiment.
Various equivalent modifications that those skilled in the art do above-described embodiment or supplement, all should fall into the protection domain of this patent.
