Abstract
The utility model discloses a stop valve, which comprises a valve body (1), a valve sleeve (3), a hand wheel (4), a valve rod (5) fixed with the handle wheel (4), whose lower end is in the valve sleeve (3), a valve core (2) connected with the rod (5) in the sleeve (3), and two sealing rings (6, 10) at the fit portion of the sleeve (3) and the valve body (1) and the fit portion of the sleeve (3) and the rod (5). The utility model is characterized in that the valve core (2) and the valve rod (5) are connected via screws, whose connecting portion (2a) is a cylinder of regular polygon, the lower end of the valve sleeve (3) is provided with a regular polygon hole engaged with the cylinder, the top of the valve rod (5) in the valve sleeve (3) is provided with a stop step (8). The stop valve has the advantages of long service life and simple operation.
Description
Technical field
The utility model relates to a kind of stop valve.
Background technique
Be widely used in the stop valve of fluid circuit at present, its structure is as shown in Figure 1: comprise valve body 11, valve pocket 13, handwheel 14, connect firmly with handwheel 14 and the lower end is positioned at the seal ring 16,17 of valve rod 15, the spool 12 that is connected with the valve rod of valve pocket 13 of valve pocket 13, the cooperation place that is arranged at valve pocket 13 and valve body 11 and valve pocket 13 and valve rod 15 cooperation places, the stage casing of valve rod 15 and valve pocket 13 are by being threaded, and its lower end and spool connect firmly; Rotation hand wheel 14 during work, the screw thread that matches with valve pocket 13 by valve rod 15, spool 12 rotations are descended, with the sealing of the valve seat in the valve body 11, thereby play effect by cutout, but because spool 12 is rotation and liftings, the friction that when spool 12 contacts with valve seat, can rotate, thus add the wearing and tearing of big valve core 12; When rotation hand wheel 14, valve rod 15 together with handwheel 14 self also will with on move, taken the user operating space, so this kind structure has shortcomings such as short, operation inconvenience in working life.
The model utility content
The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, and a kind of stop valve is provided, and it has long service life, easy to operate advantage.
The purpose of this utility model is achieved in that
A kind of stop valve, comprise valve body, valve pocket, handwheel, connect firmly with handwheel and the lower end is positioned at the seal ring of the valve rod of valve pocket, the spool that is connected with the valve rod of valve pocket, the cooperation place that is arranged at valve pocket and valve body and valve pocket and valve rod cooperation place, it is characterized in that described spool and valve rod are by being threaded, its linkage section is the cylinder of regular polygon, the valve pocket lower end is provided with the regular polygon hole with this cylinder coupling, and the valve rod top in valve pocket is provided with a limited step;
As further optimization of the present utility model, described spool bottom end is provided with the silica gel sheet, can strengthen the effect of damming of spool;
Working procedure of the present utility model is: rotation hand wheel, because limited step effect, handwheel and valve rod only rotate, can not rotate, the spool of valve rod lower end is because its linkage section is the cylinder of regular polygon, and the valve pocket lower end is provided with the regular polygon hole with this cylinder coupling, so also limited the rotation of spool, so spool can only be done up by screw thread or moves down along valve rod, thereby the valve seat in the valve body is opened or sealed, realize the circulation of tube fluid or end;
The utility model has following advantage than prior art:
The utility model when work spool can not rotate, can only move up and down, spool and valve seat rub without spin, it is little to wear and tear, so that the utility model possesses user's usage space is big, easy to operate, the advantage of long service life.
Description of drawings
Fig. 1 is the plan view of existing stop valve.
Fig. 2 is that the utility model embodiment's master cuts open figure.
Fig. 3 is the sectional drawing at A-A place among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
By Fig. 2 and shown in Figure 3, this stop valve, comprise valve body 1, valve pocket 3, handwheel 4, connect firmly with handwheel 4 and the lower end is positioned at the seal ring 6 and 10 of valve rod 5, the spool 2 that is connected with the valve rod 5 of valve pocket 3 of valve pocket 3, the cooperation place that is arranged at valve pocket 3 and valve body 1 and valve pocket 3 and valve rod 5 cooperation places, described spool 2 and valve rod 5 are by being threaded, its linkage section 2a is orthohexagonal cylinder, valve pocket 3 lower ends are provided with the regular hexagon hole with this cylinder coupling, and 5 tops of the valve rod in valve pocket 3 are provided with a limited step 8, are provided with silica gel sheet 9 at the bottom end of spool 2;
Rotation hand wheel, because limited step 8 effects, handwheel 4 rotates with 5 of valve rods, can not rotate, the spool 2 of valve rod 5 lower ends is because its linkage section is the cylinder of regular polygon, and valve pocket 3 lower ends are provided with the regular hexagon hole with this cylinder coupling, so also limited the rotation of spool 2, so spool 2 can only be done up by screw thread or moves down along valve rod 5, thereby the valve seat in the valve body 1 is opened or sealed, realize the circulation of tube fluid or end.
Claims (2)
1, a kind of stop valve, comprise valve body (1), valve pocket (3), handwheel (4), connect firmly with handwheel (4) and the lower end is positioned at the valve rod (5) of valve pocket (3), with the spool (2) that is connected of valve rod (5) in the valve pocket (3), be arranged at valve pocket (3) and the cooperation place of valve body (1) and sealed picture (6) and (10) of valve pocket (3) and valve rod (5) cooperation place, it is characterized in that described spool (2) and valve rod (5) are by being threaded, its linkage section (2a) is the cylinder of regular polygon, valve pocket (3) lower end is provided with the regular polygon hole with this cylinder coupling, and valve rod (5) top in valve pocket (3) is provided with a limited step (8).
2, stop valve according to claim 1 is characterized in that described spool (2) bottom end is provided with silica gel sheet (9).
