Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a butterfly valve with a heating function. Background Art

[0002] The butterfly valve is a simple regulating valve that can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a cutting and throttling role in the pipeline and rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating.

[0003] The Chinese utility model patent application number 201921147761.4 proposes an automatic heating and crystallization-proof intelligent electric butterfly valve. The butterfly valve includes a valve body, a water flow sensor is fixedly installed on the top of the right side of the inner cavity of the valve body, a heating box is provided on the outer side of the valve body, and a heating coil is provided in the inner cavity of the heating box and on the outer side of the valve body. Air holes are provided at the top and bottom of the inner cavity of the heating box, and the upper and lower ends of the left and right sides of the inner cavity of the heating box are fixedly connected with fixing rods. The utility model solves the problem that the existing electric butterfly valve does not have the function of automatic heating through the functions of the valve body, the heating box, the fixing rod, the heating coil, the temperature sensor, the water flow sensor, the control box and the PLC controller. Due to the long-term switching of the control liquid, and the long-term static low-temperature state of some liquids, it is very easy to crystallize. Once crystallized, it will affect its normal switching, and in severe cases, it will directly cause damage.

[0004] After improvement, the above device solves the problem that the existing electric butterfly valve does not have the function of automatic heating. Since its valve body and heating function component are fixedly connected, it cannot be replaced after the heating function is damaged by external damage after long-term use, resulting in the need to replace the entire butterfly valve. Secondly, it is easy to be damaged by bumps during transportation. For this reason, we propose a butterfly valve with heating function. Utility Model Content

When the threaded rod operates, it drives the slider to move and inserts the clamping block into the interior of the connecting box 2. Then, the magnetic block is released so that the magnetic block and the magnetic plate are attracted to each other, thereby making the connection between the magnetic block and the clamping block firm and completing the installation of the heating plate. It is simple and fast, and can be disassembled and transported separately to avoid damage from bumps. At the same time, it can be replaced separately after damage, which is more practical.

[0014] 2. The butterfly valve with heating function is connected to the input pipe through flange 1 and connected to the output pipe through flange 2, so that the flowing material enters the valve body from flange 1 and is heated by the heating ring set inside the heating plate to avoid crystallization.
