Abstract
The utility model relates to a gate valve which comprises a valve body, wherein the outside of the valve body is provided with a compensator. The compensator comprises a flange sleeve, a gland and sealing filler, the flange sleeve and the gland are arranged outside the valve body, the flange sleeve and the gland are fixedly connected, the sealing filler is arranged between the flange sleeve and the gland, and the flange sleeve and the gland are connected through a fastener. When the gate valve needs to be opened or closed, the fastener is loosened in a screwing mode so that the gland and the filler are loosened, the valve body and the flange sleeve can relatively move, and the function of compensating axial displacement of the valve is achieved. The compensator is low in manufacturing cost, use performance of the gate valve is guaranteed, and meanwhile, use cost of the gate valve is reduced. The compensator is suitable for a gate valve with a large aperture and also suitable for gate valves with medium apertures and small apertures, and is wide in applicable range.
Description
Technical field
The utility model relates to a kind of push-pull valve, relates in particular to the push-pull valve that a kind of user cost is low, belongs to valve technology field.
Background technique
Push-pull valve claims again hand knife type gate valve, it is the valve of a kind of flashboard and valve seat close contact sealing all the time, its principle is the round mouth that has a latus rectum size on flashboard, open and close and make the action that on flashboard, round mouth is finished total detachment and matched with latus rectum by flashboard, because push-pull valve is simple in structure, lightweight, good sealing effect is widely used on the gas pipe line of metallurgical system.Axial displacement in use, can occur in push-pull valve, common, and the valve body of push-pull valve is provided with corrugated expansion joint outward and compensates the axial displacement that push-pull valve occurs.But the corrugated expansion joint manufacture cost is large, increased the user cost of push-pull valve.
The model utility content
The utility model purpose is the push-pull valve that provides a kind of user cost low in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of push-pull valve, comprise valve body, and described valve body is provided with compensator outward, and described compensator comprises flange cover, gland and stuffing box packing; Described flange cover and gland are arranged on outside valve body; Described flange cover is fixedly connected with gland; Be provided with stuffing box packing between described flange cover and gland.
Preferably, described flange cover is connected by fastening piece with gland.
Preferably, described fastening piece is clamping bolt.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Push-pull valve of the present utility model, when needs open and close, unscrew fastening piece, makes gland and filler unclamp, and valve body and flange cover just can carry out relative movement, reach the effect of recuperation valve door-hinge to displacement.This compensator low cost of manufacture has reduced the user cost of push-pull valve when having guaranteed the push-pull valve usability.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is push-pull valve of the present utility model;
Wherein: 1, valve body; 2, flange cover; 3, gland; 4, stuffing box packing; 5, clamping bolt.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of push-pull valve as shown in Figure 1, comprise valve body 1, the outer compensator that is provided with of described valve body 1, and described compensator comprises flange cover 2, gland 3 and stuffing box packing 4; Described flange cover 2 and gland 3 are arranged on outside valve body 1; Described flange cover 2 is fixedly connected with gland 3; Described flange cover 2 and 3, gland are provided with stuffing box packing 4; Described flange cover 2 is connected by fastening piece with gland 3; Described fastening piece is clamping bolt 5.
Push-pull valve of the present utility model, when needs open and close, unscrew clamping bolt, makes gland and filler unclamp, and valve body and flange cover just can carry out relative movement, reach the effect of recuperation valve door-hinge to displacement.This compensator low cost of manufacture has reduced the user cost of push-pull valve when having guaranteed the push-pull valve usability.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
