Problems solved by technology

A more typical example is an electric ball valve recommended by CN201126036Y and a multi-functional explosion-proof electric ball valve for mining provided by CN201679982U. The structures of these two patents are basically the same, but there are disadvantages of complex structure, and the stability of the ball valve opening and closing Difficult to guarantee

Abstract

The invention provides an electric ball valve structure, belonging to the technical field of safety facilities for mining. The electric ball valve structure comprises a shell body, a ball valve opening and closing mechanism, an electric ball valve body, a signal acquisition mechanism and a control circuit board, wherein the shell body is provided with a shell cavity and is equipped with a power line entry device; the ball valve opening and closing mechanism is arranged in the shell cavity; the electric ball valve body is provided with a water inlet and a water outlet and is arranged on the outer walls of the shell body, a ball valve shaft of the electric ball valve extends into the shell cavity and is connected with the ball valve opening and closing mechanism, and a cam plate is fixedly arranged at the tail end of the ball valve shaft; the signal acquisition mechanism is arranged in the shell cavity and at the position corresponding to the cam plate; the control circuit board is fixed in the shell cavity and is used to provide a battery of direct-current power supply for the ball valve opening and closing mechanism, and the battery is arranged in the shell cavity, wherein the signal acquisition mechanism and the ball valve opening and closing mechanism are connected with the control circuit board in an electrically control mode. The invention has the characteristics of stable opening and closing of the ball valve and compact structure, and is convenient to produce, install and maintain.

Description

technical field [0001] The invention belongs to the technical field of mine safety facilities, and in particular relates to an electric ball valve structure. Background technique [0002] In coal mine shafts, metal mines and non-metal mines, etc., dust prevention and removal are required according to regulations. Spray measures are usually used for dust prevention and dust removal. The shower head, when it needs to be activated, that is, when spraying, the electric ball valve is driven by the motor, so that the water inlet and outlet of the electric ball valve are connected, and the water source is introduced into the spray pipe connected with the water outlet of the electric ball valve through the water inlet of the electric ball valve. spray. [0003] Electric ball valves have been reported in published patent documents, such as CN2449020Y (electric ball valve), CN201078484Y (low power consumption and light torque electric ball valve) and CN201344277Y (intrinsically safe ...
