Abstract
The utility model relates to a compensator which comprises a flange sleeve, a gland and sealing filler. The flange sleeve is fixedly connected with the gland, the sealing filler is arranged between the flange sleeve and the gland, the flange sleeve is connected with the gland through a fastener, and the fastener is a fastening bolt. The compensator is simple in structure, low in manufacturing cost, good in compensation effect, capable of being used for gate valves with different apertures and wide in application range, and overcomes the defect that an existing corrugated compensator can only be used for a gate valve with a large aperture.
Description
Technical field
The utility model relates to a kind of compensator, relates in particular to a kind of compensator applied widely, 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.FlexbleJoint belongs to a kind of compensating element.Utilize effective dilatation of its operative body bellows, to absorb pipeline, conduit, container etc. by the dimensional changes former thereby that produce such as expand with heat and contract with cold, or compensation pipes, conduit, container etc. axially, laterally and angular displacement.But corrugated expansion joint is only applicable to bigbore push-pull valve, in, small-bore push-pull valve, bellows compensation is not too applicable, if in, small-bore push-pull valve uses the bellows compensation, compensation effect is poor, does not reach and requires the compensation requirement.
The model utility content
The utility model purpose is the compensator that a kind of push-pull valve applied widely is provided 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 compensator comprises flange cover, gland and stuffing box packing; 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:
Compensator of the present utility model, simple in structure, low cost of manufacture, compensation effect is good, applicable to the push-pull valve of any bore, applied widely, has overcome the deficiency that FlexbleJoint in the past can only be applicable to the heavy caliber push-pull valve.
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, flange cover; 2, gland; 3, stuffing box packing; 4, 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 compensator as shown in Figure 1, comprise flange cover 1, gland 2 and stuffing box packing 3; Described flange cover 1 is fixedly connected with gland 2; Described flange cover 1 and 2, gland are provided with stuffing box packing 3; Described flange cover 1 is connected by fastening piece with gland 2; Described fastening piece is clamping bolt 4.
Compensator of the present utility model, described flange cover is arranged on outside the valve body of push-pull valve with gland, during use, unscrews clamping bolt, makes gland and filler unclamp, and the flange cover just can carry out relative movement with valve body, reaches the effect of recuperation valve door-hinge to displacement.Compensator of the present utility model, simple in structure, low cost of manufacture, compensation effect is good, applicable to the push-pull valve of any bore, applied widely, has overcome the deficiency that FlexbleJoint in the past can only be applicable to the heavy caliber push-pull valve.
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.
Claims (3)
