In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of vacuum separation valve, this vacuum separation valve, simple structure, easy to use and can sealing greatly.
The technological scheme adopted for solving the problems of the technologies described above the utility model is: a kind of vacuum separation valve: comprise valve body, valve gap, spool, valve rod, described valve gap is connected to above valve body, described spool is slidably connected at valve body inside cavity, described valve rod runs through valve gap, one end and spool are fixed together, described valve body comprises: limiting board, pipeline, valve rod, described valve rod is connected to pipeline upper surface, limiting board is then connected to pipeline lower surface, its innovative point is: described valve rod is also coated with a bellows outward, bellows two ends are connected on valve gap and spool by the mode of welding, the outer round surface of described spool is provided with one deck zinc by the mode of plating, described valve rod and adopt the Placement of global formation between limiting board and pipeline, described valve gap and valve body adopt the Placement of welding, described valve rod outer round surface lower end is provided with outside thread, and the step of spool is provided with internal thread, and valve rod is connected by thread fiting mode with spool, adopts the mode of welding to be fixed joint and then, described valve rod outer round surface upper end is provided with trapezoidal outside thread, is provided with trapezoidal internal thread, together with valve rod and valve gap are cooperatively interacted by trapezoidal thread in the middle of valve gap.
Further, the thickness of the outer round surface electrogalvanizing of described spool is 2 ~ 5mm.
Further, the transitional surface that described bellows two ends and valve gap and spool are welded to connect is provided with seal coating.
Compared with prior art, the beneficial effects of the utility model are:
1. this apparatus design is compact, rational in infrastructure, and what adopt global formation is fixedly connected with mode, can improve the rigidity of single unit system, and Long-Time Service can not cause distortion empty.
2. this device arranges the sealing that bellows can effectively ensure between spool and valve gap, and when opening spool by valve rod, according to the characteristic of bellows, can ensure smooth opening by elasticity.
3. this device adopts the Placement of welding, greatly can improve tightness, strengthens rigidity.
4. this apparatus structure is simple, and manufacture cost economy is lower to operator's difficulty, is applicable to extensive universal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of vacuum separation valve of the utility model, main structure is: comprise valve body 1, valve gap 2, spool 3, valve rod 4, valve gap 2 is connected to above valve body 1, and spool 3 is slidably connected at valve body 1 inside cavity, and valve rod 4 runs through valve gap 2, one end and spool 3 are fixed together, valve body 1 comprises: limiting board 1b, pipeline 1a, valve rod 1c, and valve rod 1c is connected to pipeline 1b upper surface, and limiting board 1b is then connected to pipeline 1a lower surface.
Embodiment 1
The present invention is on the basis of said structure, as Fig. 1, valve rod 4 is outer is also coated with a bellows 5, bellows 5 two ends are connected on valve gap 2 and spool 3 by the mode of welding, the sealing that bellows can effectively ensure between spool and valve gap is set, and when opening spool by valve rod, according to the characteristic of bellows, can smooth opening be ensured by elasticity; The outer round surface of spool 3 is provided with one deck zinc by the mode of plating, and the thickness of the outer round surface electrogalvanizing of spool 3 is 2 ~ 5mm; Valve rod 1c and adopt the Placement of global formation between limiting board 1b and pipeline 1a, what adopt global formation is fixedly connected with mode, can improve the rigidity of single unit system, and Long-Time Service can not cause distortion empty; Valve gap 2 and valve body 1 adopt the Placement of welding, adopt the Placement of welding, greatly can improve tightness, strengthen rigidity; Valve rod 4 outer round surface lower end is provided with outside thread, and the step of spool 3 is provided with internal thread, and valve rod 4 is connected by thread fiting mode with spool 3, adopts the mode of welding to be fixed joint and then; Valve rod 4 outer round surface upper end is provided with trapezoidal outside thread, is provided with trapezoidal internal thread, together with valve rod 4 and valve gap 2 are cooperatively interacted by trapezoidal thread in the middle of valve gap 2; The transitional surface that bellows 5 two ends and valve gap 2 and spool 3 are welded to connect is provided with seal coating.
