Abstract

The utility model discloses a gate valve. The gate valve comprises a valve body and a flashboard arranged inside the valve body. Pressing plates are arranged on the two sides of the valve body and connected to the valve body through screws. A steel jacket is arranged on the portion, between the flashboard and the pressing plates, of the valve body, and an annular groove is formed in one side, close to the flashboard, of the steel jacket and provided with a wear-resisting ring. The gate valve is good in sealing performance, the wear-resisting ring just needs to be maintained or replaced after being worn, and therefore the maintenance materials are saved, and the service life of the valve is prolonged.

Description

A kind of push-pull valve
Technical field
The utility model relates to valve mechanical field, relates in particular to a kind of push-pull valve.
Background technique
Push-pull valve is a kind of conventional valve, and its structural behaviour and sealing effect become the key point of this type of valve, and Chinese patent CN201220040626.1 discloses a kind of kink push-pull valve, comprising: valve body, flashboard; Flashboard is arranged in valve body, is designed with kink pressing plate on valve body, between kink pressing plate and valve body, with hexagon socket head cap screw, is fixedly connected with, and it is characterized in that: between described kink pressing plate and flashboard, be designed with kink seal ring.Between described kink seal ring outward edge and valve body, be designed with loop rubber ring.On the side of described kink seal ring, be designed with groove, be designed with counterbalance spring in groove, counterbalance spring is between kink pressing plate and kink seal ring.This model utility has following shortcoming in use: after kink seal ring is by abrasion, need to change whole kink seal ring, cause waste of material, change trouble, waste time and energy.
Model utility content
The utility model is for the problems referred to above, and a kind of simple in structure, push-pull valve of only needing to change wear-resisting ring is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of push-pull valve, comprise valve body and be arranged on the flashboard in valve body, wherein, described valve body both sides are provided with pressing plate, described pressing plate is connected by screw on valve body, described valve body is being provided with steel bushing between flashboard and pressing plate, and described steel bushing is provided with circular groove near a side of flashboard, on described circular groove, wear-resisting ring is installed.
Further, the outer rim of described steel bushing and valve body connecting part is provided with groove, in described groove, rubber ring is installed.
Further, the ring surface of described steel bushing is provided with several through holes, and several elastics are installed in described through hole.
Further, described wear-resisting ring is made by high-abrasive material.
Further, described valve body upper end is provided with the actuator being connected with flashboard.
Further, described actuator is oil hydraulic cylinder or cylinder.
The beneficial effects of the utility model are: the utility model in use, after wear-resisting ring abrasion, the wear-resisting ring or change wear-resisting ring of only needing repairing, easy to maintenance, cost is low.
Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
The structural representation of the push-pull valve that figure l is this model utility.
Reference character:
1 is that actuator, 2 is that flashboard, 3 is that valve body, 4 is that pressing plate, 5 is that steel bushing, 6 is that wear-resisting ring, 7 is that elastic, 8 is rubber ring.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
With reference to figure 1, a kind of push-pull valve as shown in Figure 1, comprise valve body 3 and be arranged on the flashboard 2 in valve body 3, wherein, described valve body 3 both sides are provided with pressing plate 4, and described pressing plate 4 is connected by screw on valve body 3, and described valve body 3 is being provided with steel bushing 5 between flashboard 2 and pressing plate 4, described steel bushing 5 is provided with circular groove near a side of flashboard 2, and wear-resisting ring 6 is installed on described circular groove; Described steel bushing 5 is provided with groove with the outer rim of valve body 3 connecting parts, and rubber ring 8 is installed in described groove; The ring surface of described steel bushing 5 is provided with several through holes, and several elastics 7 are installed in described through hole; Described wear-resisting ring 6 is made by high-abrasive material, can extend the working life of push-pull valve; Described valve body 3 upper ends are provided with the actuator 1 being connected with flashboard 2; Described actuator 1 is oil hydraulic cylinder or cylinder.
During use, wear-resisting ring 6 and flashboard 2 frictions, good airproof performance, after wear-resisting ring 6 abrasions, only need repairing wear-resisting ring 6 or change wear-resisting ring 6, saves service material, saving engineering time, can extend the working life of whole valve, wear-resisting ring 6 compresses by elastic 7, so better tightness.
The utility model is simple in structure, easy to maintenance, maintenance cost is low.
The foregoing is only preferred embodiment of the present utility model, the utility model includes but not limited to this example, and the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
