Description

Technical Field

[0001] The utility model relates to the technical field of valve insulation, in particular to a pipeline valve insulation sleeve which is easy to install. Background Art

[0002] At present, many fields need to insulate or heat-hold pipelines. For example, the connecting pipelines between reactors in the chemical industry, the thermal pipelines in the thermal industry, the oil pipelines in the petroleum industry, etc. all need to be insulated to reduce heat loss.

[0003] A Chinese utility model patent with authorization announcement number CN214579738U in the related technology discloses a nano-flexible detachable pipeline valve insulation cover, including an insulation cover body, the cover wall of which is provided with a protective layer, an insulation layer composited with nano-insulation felt and a PTFE coated cloth in sequence from the inside to the outside; an installation part is provided between the edges of the opening of the insulation cover body, and the installation part includes a first tightening band connected to one side of the opening of the insulation cover body, and a second tightening band connected to the other side of the opening of the insulation cover body; a first Velcro is fixed on the end of the first tightening band, and a second Velcro is fixed on the end of the second tightening band, and the first Velcro and the second Velcro are bonded together; a plurality of the installation parts are provided, and the plurality of installation parts are evenly arranged along the extension direction of the opening of the insulation cover body.

[0004] With regard to the above-mentioned related technologies, the inventor believes that a tightening belt is provided at both ends of the insulation sleeve, and it is necessary to manually tighten the two ends when knotting them so that the insulation sleeve and the pipeline valve body structure can be firmly connected to ensure the thermal insulation performance. The human influence factor is relatively large. If the tightening belt is not tightened manually or the tightening belt is loose, the thermal insulation effect cannot be guaranteed, resulting in a significant reduction in the thermal insulation effect, poor thermal insulation effect, and a waste of manpower, material resources, financial resources and time. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a pipeline valve insulation cover that is easy to install to solve the problems in the above-mentioned background technology.

[0006] The purpose of the utility model is achieved by adopting the following technical scheme: a pipeline valve insulation cover which is easy to install, comprising a first insulation cover, one end of the first insulation cover is sewn with a second insulation cover by high temperature resistant thread to form a whole, one end edge of the first insulation cover is sewn with Velcro, the other end edge of the second insulation cover is sewn with Velcro, the top edge of the first insulation cover and the top edge of the second insulation cover are symmetrically sewn with a bag tube, the inner side of the bag tube is provided with a drawstring, and the outer side of the drawstring is movably connected with a tightening buckle.

[0007] Preferably, the first thermal insulation cover and the second thermal insulation cover are provided with a hot surface layer, a thermal insulation layer and a cold surface layer in sequence from the inside to the outside.

[0008] Preferably, the hot surface layer is high-silica cloth; the thermal insulation layer is super cotton; and the cold surface layer is high-silica cloth and steel mesh cloth.

[0009] Preferably, the Velcro closure is bonded to the Velcro fleece surface.

[0010] Preferably, the drawstring is used to adjust the size of the tube wrapping opening through the tightening buckle.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the movement of the drawstring is limited by the tightening buckle, and the tightness of the drawstring is not affected by human factors, which can avoid the phenomenon that the drawstring cannot be tightened due to human factors. In addition, the unfastening of the drawstring is not affected by human factors, thus avoiding the phenomenon that the drawstring is difficult to unfasten due to manual knotting too tight before tying, which not only ensures the thermal insulation effect but also saves installation time and procedures.

[0016] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0017] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", and "outside" are used interchangeably.

[0018] The orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] like Figure 1-Figure 3 As shown, a pipeline valve insulation cover which is easy to install comprises: a first insulation cover 1, one end of the first insulation cover 1 is sewn with a second insulation cover 2 by high temperature resistant thread, one end edge of the first insulation cover 1 is sewn with a Velcro fleece surface 33, the other end edge of the second insulation cover 2 is sewn with a Velcro fastener 4, the top of the first insulation cover 1 and the top edge of the second insulation cover are symmetrically sewn with a wrapping tube 5, the inner side of the wrapping tube 5 is provided with a drawstring 6, and the outer side of the drawstring 6 is movably connected with a tightening buckle 7.

[0021] The working principle of the utility model is as follows: when arriving at the site for installation, the Velcro piece at the opposite end of the first insulation sleeve 1 is adhered to the Velcro fastener 4 of the second insulation sleeve 2, and the first insulation sleeve 1 and the second insulation sleeve 2 are tied tightly to the pipeline. The user applies force to the tightening buckle 7 to pull the drawstring 6 in the mouth of the tube 5 outward. After the tightening is completed, the collection is completed. Conversely, when the user needs to repair the pipeline, he only needs to loosen the tightening buckle 7 to loosen the drawstring 6, avoiding the phenomenon that the drawstring 6 is difficult to untie due to being manually knotted too tightly before being tied, thereby ensuring the insulation effect and saving installation time and procedures.

[0022] The first insulation cover 1 and the second insulation cover 2 are provided with a hot surface layer 8, an insulation layer 9, and a cold surface layer 10 from the inside to the outside, which reduces the heat loss rate and prolongs the service life.

[0023] The hot surface layer 8 is high-silica cloth; the heat-insulating layer 9 is super cotton; and the cold surface layer 10 is high-silica cloth and steel mesh cloth.

[0024] The Velcro closure 4 is bonded to the Velcro fleece surface 33 , so that the walls of the first thermal insulation sleeve 1 and the second thermal insulation sleeve 2 fit more tightly to the pipe, and the thermal insulation effects of the first thermal insulation sleeve 1 and the second thermal insulation sleeve 2 are more stable.

[0025] The drawstring 6 can adjust the size of the opening of the bag tube 5 through the tightening buckle 7, and the tightness of the drawstring 6 is not affected by human factors. The structure is simple and the use is convenient.

[0026] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
