AI Technical Summary
The existing valve handwheel lacks anti-wear structure, which causes greater friction between hands during operation, reducing the comfort of use.
An anti-wear valve body handwheel is designed. By setting an anti-wear cover on the periphery of the handwheel body and evenly fixing anti-wear pads on its surface, the friction with personnel's hands is reduced. In addition, there is an auxiliary heating cavity inside, equipped with a constant temperature electric tape, which provides auxiliary heating in cold weather and improves grip comfort.
By setting up an anti-wear cover and an anti-wear pad, the friction between the handwheel and the hand is significantly reduced and the comfort of use is improved; the combination of the auxiliary heating chamber and the constant temperature electric tape further improves the comfort of grip under cold conditions. .

Technical Field
[0001] The utility model relates to the technical field of valve hand wheels, in particular to an anti-wear type valve body hand wheel. Background Art
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. At present, manual valves are still widely used. Manual valves are generally equipped with handwheels, which are generally disc-type and are rotated and controlled by manpower during use.
[0003] The existing handwheels also have the following defects: lack of anti-wear structure, which makes it easy for people to have large friction on their hands during operation and reduces the comfort of use. To this end, we propose an anti-wear valve body handwheel. Summary of the invention
[0004] The main purpose of the utility model is to provide an anti-wear valve body hand wheel, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A wear-resistant valve body handwheel comprises a handwheel body and a first fixing hole. A wear-resistant cover is arranged on the periphery of the handwheel body. Wear-resistant pads are evenly fixed on the outer surface of the wear-resistant cover by screws. An auxiliary heating cavity is opened in the wear-resistant cover.
[0007] Furthermore, the first fixing holes are evenly arranged around a center position on the periphery of the top surface of the handwheel body.
[0008] Furthermore, second fixing holes are evenly opened around the center position on the outer periphery of the top surface of the anti-wear cover, and a fixing bolt is threaded through the top surface of the second fixing hole, and one end of the fixing bolt is located in the first fixing hole; the anti-wear cover is enclosed around the outer periphery of the handwheel body to protect it.
[0009] Furthermore, the anti-wear pad is made of acrylic glue.
[0010] Furthermore, a constant temperature electric heating belt is fixed in the auxiliary heating cavity by screws.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] By arranging an anti-wear cover and an anti-wear pad, the anti-wear cover is used to protect the handwheel body at its periphery, and the anti-wear pad is used to reduce friction with the hand of a person when the handwheel is rotated, thereby achieving an anti-wear effect.
[0013] By providing an auxiliary heating chamber and a constant temperature electric belt, the anti-wear cover is auxiliary heated by utilizing the constant temperature electric belt in the auxiliary heating chamber, so as to enhance the comfort of personnel when gripping in cold weather.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-3 As shown, a wear-resistant valve body handwheel includes a handwheel body 1 and a first fixing hole 2. An anti-wear cover 3 is arranged on the periphery of the handwheel body 1. Anti-wear pads 6 are evenly fixed on the outer surface of the anti-wear cover 3 by screws. An auxiliary heating cavity 7 is opened in the anti-wear cover 3.
[0020] The first fixing holes 2 are evenly arranged around the center position on the periphery of the top surface of the hand wheel body 1 .
[0021] In this embodiment, Figure 1 , 2 As shown, the first fixing hole 2 is used to facilitate the penetration of the fixing bolt 5 .
[0022] The outer periphery of the top surface of the anti-wear cover 3 is evenly provided with second fixing holes 4 around the center position, and the top surface of the second fixing hole 4 is penetrated by a fixing bolt 5 through a thread, and one end of the fixing bolt 5 is located in the first fixing hole 2.
[0023] In this embodiment, Figure 1 , 2 As shown in FIG. 3 , the anti-wear cover 3 is fixed to the hand wheel body 1 by means of a fixing bolt 5 penetrating through the second fixing hole 4 and the first fixing hole 2 .
[0024] Wherein, the anti-wear pad 6 is acrylic glue.
[0025] In this embodiment, Figure 1 As shown, acrylic structural adhesive is excellent in resistance to acid, alkali, water and oil media, and has better high temperature resistance and aging resistance.
[0026] Wherein, a constant temperature electric belt 8 is fixed in the auxiliary heating chamber 7 by screws.
[0027] In this embodiment, Figure 3 As shown, the constant temperature electric heating belt 8 is fixed by the auxiliary heating chamber 7.
[0028] It should be noted that the utility model is an anti-wear valve body handwheel. During installation, the fixing bolt 5 is passed through the second fixing hole 4 and the first fixing hole 2 so that the anti-wear cover 3 is fixed to the periphery of the handwheel body 1. During use, the anti-wear pad 6 on the periphery of the anti-wear cover 3 can reduce the friction with the hands of the personnel when the handwheel is rotated, thereby achieving an anti-wear effect. When the weather is cold, the constant temperature electric heating belt 8 (production model: ZXW-J of Hefei Walter Electric Heating Materials Co., Ltd.) can be connected to an external power supply, and the constant temperature electric heating belt 8 in the auxiliary heating chamber 7 can be turned on to perform auxiliary heating on the anti-wear cover 3 to improve the comfort of the personnel when gripping.
