A kind of antifreeze two-way valve

Abstract

The invention discloses an antifreeze two-way valve, which relates to the field of valves. It is an antifreeze two-way valve. A power box is fixedly connected to the valve pipe. A pair of through holes are dug on the power box. A rotating shaft is connected to the through hole and fixedly connected to the through hole. There is a valve disc, and a mounting hole is drilled on the valve disc, and a pressure relief plate is fixedly connected in the mounting hole. The pressure relief plate includes a pair of floating sealing plugs, and a fixed shaft cylinder is arranged between the pair of floating sealing plugs. The fixed shaft tube is fixedly connected with the inner wall of the installation hole of the valve disc, and the fixed shaft tube is fixedly connected with a mesh plate, and a plurality of hollow tennis balls are fixedly connected on the mesh plate. There is a diversion cylinder, and a one-way air valve is fixedly connected to the floating sealing plug near one end of the diversion cylinder, which can make the pressure relief plate on the valve disc vibrate and generate heat when the water accumulates in the valve and condenses the ice layer, making the periphery of the valve disc vibrate and generate heat. The ice layer ice is shattered and melted to prevent the valve body from cracking due to the expansion of the ice layer.

Description

Technical field [0001] The present invention relates to the field of valve, and more particularly to a non-freezing bidirectional valve. Background technique [0002] The valve is a mechanical device that controls flow, flow, pressure, and temperature, or the like, and the valve are basic components in the conduit system. The valve fittings are technically discussed as a separate category as a pump. The valve can be manually or handle, handle or pedal operation, or by controlling the pressure, temperature, and flow rate of the fluid medium. Valves can be continuous or repeated for these changes, such as safety valves installed in hot water systems or steam boilers. [0003] In the cold winter, the temperature is lower than the zero, the exit pipe valve exposed to the external air is easily freezed, affecting the use, even freeze, causing unnecessary losses, existing antifreeze valves generally use electric heating The temperature around the valve is improved, and the method of co...

AI Technical Summary

Problems solved by technology

[0003] In the cold winter, when the temperature is below zero, the outlet pipe valves exposed to the outside air are easy to freeze, affecting the use, and even cracking, causing unnecessary losses. The existing antifreeze valves generally use electric heating. Increase the temperature around the valve to prevent the door from freezing, but there are problems such as unreasonable structural design, time-consuming and laborious replacement and maintenance in the later stage
