Description

A kind of anti-loosening pressure pipeline gasket seal
Technical field
The utility model is applied to industrial circle, specially a kind of anti-loosening pressure pipeline gasket seal.
Background technique
Gasket seal, as long as it is that a kind of place for having fluid for machinery, equipment, pipeline is used with sealing spare part, Using inside and outside, the material to seal, gasket seal is with metal or nonmetallic plate material, through cutting, punching press or sanction It the techniques such as cuts to be made, for the sealed connection between pipeline, sealed connection between the parts and parts of machinery equipment, by material Metallic packing and nonmetallic gasket seal can be divided into.Metal has a copper backing, stainless steel gasket, iron gasket, aluminium backing etc., Nonmetallic have an asbestos washer, non-asbestos gasket, paper gasket, rubber sheet gasket etc., in the pipeline of some high voltage operations, enclosed watch The phenomenon that face usually loosens influences the progress of work.
Utility model content
The purpose of this utility model is that a kind of anti-loosening pressure pipeline gasket seal is proposed, to solve above-mentioned background technique The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of anti-loosening pressure pipeline gasket seal Including gasket, the upper and lower surface of the gasket is equipped with flange, and the flange and gasket are linked together by screw bolt and nut, institute It states and is equipped with auxiliary spacer below nut, the auxiliary spacer includes clout body, and the upper surface of described clout body is equipped with auxiliary pawl, Cushion cover is equipped with below the auxiliary spacer, the cushion cover includes spacer layer, and the spacer layer is equipped with and the auxiliary spacer The pawl that auxiliary pawl matches, the upper surface of described spacer layer are equipped with tapped through hole, are equipped with body, institute below the spacer layer The end for stating body is equipped with screw thread, and the screw thread is connected on gasket.
Preferably, the lower surface of the auxiliary spacer is set as large roughness.
Preferably, spring shim is equipped between the auxiliary spacer and cushion cover.
Compared with prior art, the utility model has the beneficial effects that passing through the phase interworking of cushion cover and auxiliary spacer pawl It closes, rotate nut can not relative to flange, that is, allow bolt and nut that can not rotate, so being that sealed connection between flange can not be loose It is dynamic.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model;
Fig. 2 is the structure chart of the cushion cover of the utility model;
Fig. 3 is the structure chart of the auxiliary spacer of the utility model.
In figure: 1 nut, 2 auxiliary spacers, 21 auxiliary pawls, 22 clout bodies, 3 cushion covers, 31 tapped through holes, 32 pawls, 33 pads Lamella, 34 bodies, 35 screw threads, 4 flanges, 5 gaskets, 6 bolts.
Specific embodiment
In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen The feature in embodiment and embodiment please can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical It is novel to be implemented using other than the one described here mode, therefore, the protection scope of the utility model not by The limitation of following public specific embodiment.
Fig. 1 to 3 is please referred to, the utility model provides a kind of technical solution: a kind of anti-loosening pressure pipeline gasket seal packet Gasket 5 is included, the upper and lower surface of the gasket 5 is equipped with flange 4, the flange 4 and gasket 5 and is connected to one by bolt 6 and nut 1 It rises, auxiliary spacer 2 is equipped with below the nut 1, the auxiliary spacer 2 includes clout body 22, the upper surface of described clout body 22 Equipped with auxiliary pawl 21, cushion cover 3 is equipped with below the auxiliary spacer 2, the cushion cover 3 includes spacer layer 33, the spacer layer 33 are equipped with the pawl 32 matched with the auxiliary pawl 21 of the auxiliary spacer 2, and the upper surface of described spacer layer 33 is logical equipped with screw thread Hole 31 is equipped with body 34 below the spacer layer 33, and the end of the body 34 is equipped with screw thread 35, and 35 screw thread of screw thread connects It connects on gasket 5.
Specifically, the lower surface of the auxiliary spacer 2 is set as large roughness, prevent from sending out between auxiliary spacer 2 and nut 1 Raw rotation.
Specifically, being equipped with spring shim between the auxiliary spacer 2 and cushion cover 3, increase the pressure between gasket, increase rubs Wipe power.
Working principle: when in use, since upper and lower two cushion covers 3 are screwed on gasket 5, upper and lower two cushion covers are mutually pushed up Extremely, so cushion cover 3 can not loosen on gasket 5, while pawl 21 and 32 phase interworking of pawl are assisted on cushion cover 5 and auxiliary spacer 2 It closes, so can not loosen, can effectively prevent the loosening between bolt 6 and nut 1 in this way.Between the fixing piece for preventing sealing surface Loosening.
In the description of this specification, term " connection ", " installation ", " fixation " etc. shall be understood in a broad sense, for example, " even Connect " it may be fixed connection or may be dismantle connection, or integral connection;It can be directly connected, it can also be in Between medium be indirectly connected.For the ordinary skill in the art, above-mentioned term can be understood at this as the case may be Concrete meaning in utility model.
In the description of this specification, the description of term " one embodiment ", " some embodiments ", " specific embodiment " etc. Mean that particular features, structures, materials, or characteristics described in conjunction with this embodiment or example are contained at least the one of the utility model In a embodiment or example.In the present specification, schematic expression of the above terms are not necessarily referring to identical embodiment Or example.Moreover, the particular features, structures, materials, or characteristics of description can be in any one or more embodiment or examples In can be combined in any suitable manner.
