Abstract
The utility model discloses an assistance type gate valve which comprises a valve body, a valve deck, a valve plate, a valve rod, a hand wheel, a valve seat, a pressure-leading pipe, an assistance piston, a supporting ring, a supporting disk, a supporting rod, an assistance cylinder and an assistance support. The assistance cylinder is arranged on the valve deck; the upper end of the valve rod is connected with the hand wheel, and the lower end of the valve rod sequentially penetrates through the assistance cylinder and the valve deck and then is connected with the valve plate; the lower section of the valve rod is sleeved with the supporting disk; the supporting rod is arranged between the valve deck and the supporting disk; the assistance support is arranged between the upper end in the assistance cylinder and the valve deck; the lower section of the assistance support is sleeved with the supporting ring and the assistance piston; the two ends of the pressure-leading pipe are arranged in a space formed by the assistance cylinder and the valve deck and a space formed by the assistance cylinder and the valve body respectively. Compared with the prior art, the assistance type gate valve has the advantages of being simple in structure, low in cost, good in leakproofness, capable of saving labor in the operating process and convenient to use, and having popularization value.
Description
Technical field
The utility model relates to a kind of gate valve, relates in particular to a kind of assistance type gate valve.
Background technique
The open-shut device of gate valve is flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down, can not make adjustments and throttling.Flashboard has two sealing surfaces, and two sealing surfaces of the most frequently used pattern gate valve form wedge shape, key groove is different with valve parameter, are generally 50, are 2 ° 52 ' when medium temperature is not high.The flashboard of Wedge gate valve can be made an entirety, is called rigidity flashboard; Also can make the flashboard that can produce micro-deformation, to improve its manufacturability, make up the deviation that sealing surface angle produces in course of working, this flashboard is called Flexible disc.And the complex structure of gate valve of the prior art, cost is high, volume is large, operation relatively effort, be difficult to promote.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem a kind of assistance type gate valve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises valve body, valve gap, valve plate, valve rod, handwheel, valve seat, pressure inlet tube, boosting piston, bracing ring, supporting disk, strut, servo-cylinder and power-assisted support, described servo-cylinder is arranged on described valve gap, the upper end of described valve rod is connected with described handwheel, the lower end of described valve rod is passed described servo-cylinder and is connected with described valve plate after described valve gap successively, described supporting disk is set in the hypomere of described valve rod, described strut is arranged between described valve gap and described supporting disk, described power-assisted support is arranged between the upper end and described valve gap in described servo-cylinder, described bracing ring and described boosting piston are all set in outside described power-assisted support hypomere, the two ends of described pressure inlet tube are arranged at respectively between described servo-cylinder and described valve gap and the space of described valve body formation.
Further, between described strut and described valve gap, be provided with sealing nut; Joint between described valve gap and described valve body is provided with elevation pad; Between described power-assisted support and described servo-cylinder, be provided with bearing and nut.
The beneficial effects of the utility model are:
The utility model is a kind of assistance type gate valve, compared with prior art, the utlity model has advantage simple in structure, with low cost, good leak tightness, and especially the utility model operation is more laborsaving, easy to use, has the value of popularization.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
In figure: 1-pressure inlet tube, 2-valve rod, 3-boosting piston, 4-bracing ring, 5-sealing nut, 6-valve body, 7-valve seat, 8-handwheel, 9-bearing, 10-nut, 11-power-assisted support, 12-servo-cylinder, 13-valve gap, 14-elevation pad, 15-strut, 16-supporting disk, 17-valve plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises valve body 6, valve gap 13, valve plate 17, valve rod 2, handwheel 8, valve seat 7, pressure inlet tube 1, boosting piston 3, bracing ring 4, supporting disk 16, strut 15, servo-cylinder 12 and power-assisted support 11, servo-cylinder 12 is arranged on valve gap 13, the upper end of valve rod 2 is connected with handwheel 8, the lower end of valve rod 2 is connected with valve plate 17 with after valve gap 13 through servo-cylinder 12 successively, supporting disk 16 is set in the hypomere of valve rod 2, strut 15 is arranged between valve gap 13 and supporting disk 16, power-assisted support 11 is arranged between the upper end and valve gap 13 in servo-cylinder 12, bracing ring 4 and boosting piston 3 are all set in outside power-assisted support 11 hypomeres, the two ends of pressure inlet tube 1 are arranged at respectively between the space that servo-cylinder 12 and valve gap 13 and valve body 6 form.Between strut 15 and valve gap 13, be provided with sealing nut 5; Joint between valve gap 13 and valve body 6 is provided with elevation pad 14; Between power-assisted support 11 and servo-cylinder 12, be provided with bearing 9 and nut 10.
As shown in Figure 1: it is stressed in boosting piston 3 that the pressure medium that pressure inlet tube 1 is taken from valve body 6 enters servo-cylinder 12, make valve rod 2 be subject to a downward power, this power balances out valve rod 2 from valve body 6 power upwards, makes valve rod 2 in state of equilibrium, and valve operation gets up just more laborsaving.
