Antifreezing valve with self-cleaning function

Abstract

The invention discloses an antifreezing valve with a self-cleaning function. The antifreezing valve comprises a valve body, wherein a valve cavity is formed in the valve body; a ball valve is arranged in the valve cavity; a valve rod is connected with the ball valve; the valve rod extends out from a valve rod hole in the valve body to be connected with a hand wheel; a valve cover covers the valve rod hole; a water inlet channel and a water outlet channel which are both communicated with the valve cavity, are connected with the valve body; the valve rod is a hollow valve rod in which a stirring shaft is arranged in a penetrating manner; the lower end of the stirring shaft extends into the ball valve to be connected with a stirrer which is arranged in the valve body; the upper end of the stirring shaft is connected with a micro motor which is used for driving the stirring shaft to work; the micro motor is arranged in a cavity of the hand wheel; electromagnetic coils are arranged on the inner walls of both the water inlet channel and the water outlet channel respectively in a winding manner, and are electrically connected with a pulse current generator. According to the antifreezing valve with the self-cleaning function, the micro motor controls the stirrer to work intermittently, so that the liquid medium in the valve is in a non-static state, the scale deposition and medium freezing are avoided and the aims of scale prevention and self-cleaning are achieved.

Description

technical field [0001] The invention relates to an antifreeze valve with self-cleaning function, which belongs to the technical field of valves. Background technique [0002] In many industrial environments, many pipelines and valves installed on pipelines are set in the open air. In northern my country, winter is very cold. In this case, the valve may be cracked due to the freezing of the conveying medium, which will affect the normal conveying of the medium. In addition, under normal circumstances, in order to ensure good sealing performance of the valve, the valve body is cast in one piece, which makes it difficult to clean the dirt accumulated in the valve body. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide an antifreeze valve with self-cleaning function, and solve the technical problem that the valve is easy to freeze and scale in the prior art. [0004] In order to solve the above-...
