Description

Technical Field

[0001] The utility model belongs to the technical field of valve driving, and in particular relates to a valve driver. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, flow diversion, prevention of backflow, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] Existing valves have various specifications. Existing valves rely on manual operation for opening and closing and use a drive motor and a transmission gear set to form a drive unit to drive the electric valve. The transmission gear set is connected between the motor and the electric valve, so that the motor can open and close the valve. With the advancement of intelligence, driven valves have gradually become the mainstream, but driven valves are expensive, resulting in a large amount of cost for updating traditional valves to driven valves, which is not conducive to the replacement of traditional valves. Utility Model Content

[0009] Preferably, a dustproof net is fixedly connected to the inner wall of the heat dissipation hole.

[0010] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0011] The equipment frame is welded to the traditional valve through a connecting plate, and is electrically connected to the signal terminal through a signal transceiver. The signal of the signal terminal is received through the signal transceiver, and the signal transceiver sends a signal to the controller. The controller receives the signal from the signal transceiver, and the controller controls the reduction motor to work.
