Abstract
The utility model relates to a valve which comprises a valve seat, a valve rod, a valve core and a valve cover. The valve cover is sealed on the valve seat, and the valve rod is fixed in the valve core. The utility model is characterized in that the utility model also comprises a valve core turning element with a turning handle and a valve core pressing element; the lower part of the valve seat is provided with a pipe truncated cone; the valve core is in a frustum shape, and is arranged in the pipe truncated cone; a circular table is arranged in the valve core pressing element, and a flange corresponding to the circular table is arranged on the valve rod; the valve core pressing element is respectively connected with the valve seat and the valve core turning element through screw threads; the valve core turning element is fixedly connected with the valve rod. The utility model has the advantages of simple structure and convenient operation. The utility model can be used for various places needing the valve.
Description
The utility model relates to a kind of valve.
Up to the present, ball valve, stopcock are widely used, but these two kinds of valves exist the problem that some allow production man and user have a headache really.Ball valve: the one, the spheroid processing difficulties, the 2nd, adopt soft system sealing serviceability temperature restricted, the 3rd, frequent switching, valve is prone to the phenomenon that fits badly.Stopcock: its sealing contact surface is big, and for preventing to sew, spool also additionally is added with impacting force, opens and closes quite effort.In addition, two kinds of valves all are provided with leakproof seal between valve rod and valve body, need during use often to change.
At the problems referred to above, the purpose of this utility model provides a kind of high temperature resistant, does not leak, and is easy to process, and opening and closing are valve easily.
For achieving the above object, the utility model is taked following design: a kind of valve, it comprises valve seat, valve rod, spool and valve gap, described valve bonnet seal is on described valve seat, described valve rod is fixed on the described spool, it is characterized in that: it also comprises valve core rotation part and the spool compressing member with handle with sleeve, described valve seat bottom has a pipe truncated cone, described spool is taper type, and it is installed in the described pipe truncated cone, has a round platform in the described spool compressing member, corresponding with it, have a flange on the described valve rod, described spool compressing member is connected with the valve core rotation part with described valve seat by screw thread respectively, and described valve core rotation part is fixedlyed connected with described valve rod.
The utility model is owing to adopt above design, and it has the following advantages: 1, owing to the sealing of having saved between valve rod and the valve gap, make the sealing contact of valve best.2, owing to adopt pipe truncated cone and the structural design that is the spool of taper type, therefore cooperate closely, can not leak.3, because moving surface does not have soft sealing material, thus can anti-very high temperature.4,, therefore no matter when opening and closing, all very light because moving surface does not have the sealing impacting force.5, owing to adopt the tapered cross-section, its processing is much easier than spheroid, and does not need frequent replacing.The utility model is simple in structure, and is easy to operate, and it can be used for the various places that need valve.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the utility model structural representation
As shown in Figure 1, valve gap 1 is sealed on the valve seat 2, forms one with valve seat 2.Gapped between valve gap 1 and the valve rod 3,3 of spool compressing member 4 and valve rods are gapped, and valve core rotation part 5 is fixedlyed connected with valve rod 3, and valve core rotation part 5 is threaded with spool compressing member 4, and fixed handle 6,7 is arranged on valve core rotation part 5 and the spool compressing member 4.In the middle of the spool compressing member 4 round platform 8 is arranged, there is a flange 9 at 3 middle parts of corresponding valve rod with it, and flange 9 is positioned under the round platform 8 of spool compressing member 4.Valve rod 3 be positioned at spool 10 directly over, and fixedly connected.Spool 10 is taper type, and a through hole 11 is opened in the centre.Have a tubular body in valve seat 2 bottoms, the heart cuts a circular cone therein, forms a pipe truncated cone 12.Spool 10 is placed in the pipe truncated cone 12 of valve seat 2 bottoms.When the through hole 11 of spool 10 was parallel with the direction of pipe truncated cone 12 pipes, valve was in out the position, otherwise for closing the position.
When open valve, the operator unclamps spool compressing member 4 earlier on the other hand, and proficiency rotational valve core rotating component 5 makes the through hole 11 of spool 10 parallel with the direction of pipe truncated cone 12 pipes then, and valve is promptly opened.Keep spool rotating component 5 motionless then, spool compressing member 4 is screwed, drive valve and finish.It is substantially the same with the action of driving valve to close valve, is vertical the getting final product of direction with the through hole 11 and pipe truncated cone 12 pipes of spool 10.
