Problems solved by technology

[0003] When the current valve is used in relatively cold weather, due to the moisture remaining inside the valve, icing occurs in the valve and the water pipe under low temperature conditions, which may damage the valve, and the deformation of the internal structure of the valve caused by icing It will also affect the control effect of the valve on the water flow. On the other hand, when the valve is in use, the connection between the valve and the water pipe is prone to fall off, which affects the use

Abstract

The invention relates to the technical field of valves, specifically a valve with an antifreeze function, including a valve body, a valve stem, a water inlet pipe, a water outlet pipe, a compression structure, an exhaust structure, a support structure, a drive structure and a sealing structure; The driving structure can provide the driving effect for the operation of the internal structure according to the on-off state of the valve. The moisture in the outlet pipe can be quickly discharged through the exhaust structure, and the water flow in the inlet pipe and the water inlet pipe side of the valve can be controlled through the compression structure. A certain compression makes the inside of the valve in a hollow state when the valve is closed, so as to avoid the phenomenon of icing inside the valve. The sealing structure can switch between the sealing state and the connected state of the compression chamber according to the different on-off states of the valve, which is convenient. Operation, the supporting structure can provide a further fastening effect on the connection between the valve pipe body and the water inlet pipe and the water outlet pipe, so as to avoid loosening of the connection caused by external force.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve with antifreeze function. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. As a control component in a fluid conveying system, the valve has functions such as cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and pressure relief. Valves used in fluid control systems, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have a wide variety and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal a...
