Abstract
The utility model discloses a valve pressing cover type shockproof expansion device which is composed of an upper cover, a lower cover, sealing rings, a flange, a bolt and a nut, wherein the upper cover and the lower cover are fixed together through the bolt and the nut, the lower cover is connected with the flange, a plurality of screw holes are formed in the flange, a plurality of screw holes are formed in two sides of the upper cover and the lower cover, the sealing rings are respectively arranged on the inner side wall of the upper cover pipeline and the lower cover pipeline and are made of natural rubber, the number of the sealing rings are at least two, the sealing rings are respectively arranged at the upper joint position of the upper cover and the lower joint position of the lower cover, a rubber cushion is further arranged at the flange line position, and a plurality of reinforced ribs are arranged at the outer side of the joint position of the lower cover and the flange so that the mechanical intensity of the lower cover can be effectively increased. The valve pressing cover type shockproof expansion device has the advantages of being reasonable in structure and good in sealing effect.
Description
Technical field
The utility model relates to a kind of expansion bend, specifically the shockproof expansion bend of valve gland type.
Background technique
Expansion bend also claims slip joint, expansion joint, compensator, expansion joint, but expansion bend is axial stretching within the specific limits, also can in certain angle, overcome pipeline butt joint disalignment to and the skew that produces, can greatly facilitate the installation and removal of valve pipe, allow freely to stretch in the extending amount at pipeline, just play spacingly in case cross its maximal dilation amount, guarantee the safe operation of pipeline.
But at present existing for ducted expansion bend, be symplex structure structurally, and sealing effect is poor in the using process, regular meeting reveals.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides the shockproof expansion bend of valve gland type of a kind of convenient and quick construction, good sealing effect.
The purpose of this utility model realizes by the following technical solutions:
The shockproof expansion bend of valve gland type, constituted by loam cake, lower cover, seal ring, flange, screw bolt and nut on its structure, loam cake, lower cover are fixed together by screw bolt and nut, under cover and connect a flange, it is some that flange is provided with screw, it is some to be provided with screw in loam cake and lower cover both sides, and loam cake, lower cover insides of pipes wall respectively are placed with seal ring.
Described seal ring is natural rubber, has two at least, is arranged at the upper and lower junction point of loam cake and lower cover respectively.
Described flange, its upper flange line place also is provided with rubber pad, to increase sealability, drainage exhaust when flange is used for rushing to repair.
Described lower cover and flange connections arranged outside have the multiple tracks stiffening rib, can effectively increase the mechanical strength of lower cover.
In use, select adaptive expansion bend to be enclosed within on the pipeline, with screw bolt and nut sleeve pipe is fixed then, tight a bolt, seal ring is being fixed on the tube wall tightly also, can omnibearing prevention leak.
Owing to adopted above technological scheme, the utlity model has the beneficial effect of giving:
1, simple in structure, sturdy and durable, beautiful shape;
2, maintenance speed is fast, good sealing effect;
3, be fit to the pipeline maintenance connection of various materials, shorten and need not cut off the water and just can finish repairing engineering time, not only brought convenience to resident living, and retrieved unnecessary economic loss.
Description of drawings
Fig. 1 is the utility model one example structure schematic representation;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is cross-sectional view of the present utility model.
Among the figure: 1 lower cover, 2 loam cakes, 3,30 seal rings, 4 stiffening ribs, 5 flanges, 51 flange lines.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the shockproof expansion bend of valve gland type is made of loam cake, lower cover, seal ring, flange, screw bolt and nut on its structure, and loam cake, lower cover are fixed together by screw bolt and nut, under cover and connect a flange, it is some that flange is provided with screw, and it is some to be provided with screw in loam cake and lower cover both sides, and loam cake, lower cover insides of pipes wall respectively are placed with seal ring.
Described seal ring is natural rubber, has two at least, is arranged at the upper and lower junction point of loam cake and lower cover respectively.
Described flange, its upper flange line place also is provided with rubber pad, to increase sealability, drainage exhaust when flange is used for rushing to repair.
Described lower cover and flange connections arranged outside have the multiple tracks stiffening rib, can effectively increase the mechanical strength of lower cover.
In use, select adaptive expansion bend to be enclosed within on the pipeline, with screw bolt and nut sleeve pipe is fixed then, tight a bolt, seal ring is being fixed on the tube wall tightly also, can omnibearing prevention leak.
