Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of butterfly valves, in particular to a regulating butterfly valve with a heating function. Background Art
[0002] A valve is an important control component in a pipeline system, which has the functions of flow control, opening for flow, closing for cut-off, and safety protection, enabling the pipeline system to have good flow control function and meet the usage requirements of users.
[0003] However, when a valve is used in some low-temperature environments, its interior is easily frozen or liquid accumulates and solidifies inside, resulting in the valve being unable to rotate normally. Currently, the existing solution is to heat the outside of the valve to prevent freezing inside the valve, thereby ensuring the normal use of the valve. However, with this heating method, it is easy to cause uneven temperature distribution inside the valve and unable to ensure that the butterfly plate inside can be opened / closed normally.
[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model
[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the utility model is to provide a regulating butterfly valve with a heating function.
[0006] To achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A regulating butterfly valve with a heating function includes a valve body, a driving mechanism, and a butterfly plate. The lower end of the valve body is set as an annular body. The driving mechanism is arranged at the upper end of the valve body and has a shaft extending into the annular body. The butterfly plate is arranged in the annular body and fixed on the shaft extended by the driving mechanism to rotate with it. An installation groove is further arranged at the side end of the annular body, and a heating component is arranged in the installation groove to provide heat to the annular body.
[0008] As a preference, a housing is further arranged on the valve body. The housing is arranged at the upper end of the valve body and sleeves the driving mechanism inside the housing. One end of the driving mechanism extends out from the inside to the outside of the housing, and the other end extends into the annular body.
[0009] As a preference, a through groove penetrating up and down is arranged on the top end surface of the housing. A connection port is arranged at the top end of the driving mechanism, and the connection port extends out from the through groove to be electrically connected to a central control system for controlling operation.
[0010] As a preference, the driving mechanism includes a PCB board, a driving motor, a speed reducer, a coupling and a driving shaft. The speed reducer is arranged between the driving motor and the coupling. The driving shaft is arranged at the lower end of the coupling and is used for installing and fixing the butterfly plate. The driving motor drives the driving shaft to rotate through the connection and control of the speed reducer and the coupling, so as to drive the butterfly plate to rotate and open / close. The PCB board is arranged on one side of the driving motor and is electrically connected to the driving motor for control. The PCB board is also connected to the connection port for operation control.
[0011] As a preference, the angle of rotation controlled by the driving motor is 0°-90°, so that the butterfly plate rotates to form an open / closed working state.
[0012] As a preference, the installation grooves are arranged at the left and right ends of the annular body. The installation grooves are arranged as through grooves from top to bottom. The heating components are placed in the installation grooves and provide heat to the annular body.
[0013] As a preference, the heating component is a heating wire, and one end of the heating wire is provided with a connecting wire for providing driving electric energy.
[0014] As a preference, a fixing hole is arranged at the center of the rear end of the butterfly plate. A through hole corresponding to the position of the fixing hole is arranged on the shaft extended by the driving mechanism. The butterfly plate is locked and fixed by bolts passing through the shaft extended by the driving mechanism and the fixing hole.
[0015] As a preference, a groove recessed inward is arranged at the side end of the butterfly plate. A sealing ring is also arranged in the groove. The sealing ring is embedded in the groove, and the outer surface of the sealing ring abuts against the inner end surface of the annular body. When the butterfly plate is in a closed state, the outer surface of the sealing ring abuts against the inner end surface of the annular body to form a sealed state.
[0016] The utility model has obvious advantages and beneficial effects compared with the prior art. Specifically, as can be seen from the above technical solutions:
[0017] The structure of the utility model is simple and convenient to use. By arranging heating components on the annular body, heat can be generated inside the butterfly valve, enabling the butterfly valve to work in a low-temperature environment, reducing the situation of freezing / internal liquid accumulation solidification, avoiding the butterfly valve from being unable to rotate and open / close, ensuring the stable use and safety state of the butterfly valve. And heating components are arranged at both the left and right ends of the butterfly valve, which can heat both ends simultaneously, making the butterfly valve heated evenly and better alleviating the frozen situation. Also, by arranging a sealing ring on the butterfly plate, the butterfly valve has a good sealing and protection effect, effectively avoiding liquid leakage. Description of the Drawings
