Description

Anti-freezing and anti-blocking exhaust valve Technical Field The utility model belongs to the technical field of exhaust valves, and particularly relates to an anti-freezing and anti-blocking exhaust valve. Background The exhaust valve is used as an indispensable key auxiliary element in a pipeline system and is widely applied to various pipeline systems such as boilers, petroleum and natural gas, water supply and drainage and the like. In the actual operation process, the exhaust valve is usually arranged at a high point or an elbow of the pipeline, and can effectively avoid the phenomenon of air resistance by timely exhausting the redundant gas accumulated in the pipeline, thereby remarkably improving the transmission efficiency of the pipeline system and simultaneously reducing the extra energy consumption caused by gas retention; However, when the vent valve is applied to a liquid natural gas transportation pipeline, serious technical challenges are faced. The liquid natural gas always keeps extremely low temperature in the transportation process, and the low-temperature liquid natural gas can enable ambient air to be rapidly cooled near the air outlet of the valve body, so that water vapor and part of low-boiling-point gas components in the air are liquefied and even solidified on the surface of the valve body to form frost or a frozen layer. The condensate can be gradually accumulated and block the exhaust channel, so that the normal operation of the exhaust valve is seriously affected, the gas in the pipeline cannot be smoothly exhausted, the exhaust effect of the whole pipeline is influenced, the anti-freezing and blocking capacity of the pipeline is obviously insufficient, and even serious safety problems are caused. Therefore, an anti-freezing and anti-blocking exhaust valve is provided for solving the problems. Disclosure of utility model In order to solve the problems in the background art, the utility model provides an anti-freezing and anti-blocking exhaust valve, which has the advantages of being capable of carrying out anti-freezing and anti-blocking treatment on the exhaust valve, avoiding the water vapor in the surrounding air from liquefying or solidifying to form frost or frozen layers, accumulating and blocking an exhaust passage. The utility model provides a technical scheme that the anti-freezing and anti-blocking exhaust valve comprises an exhaust valve body, wherein the top end of the exhaust valve body is communicated with an air outlet pipe, and an anti-freezing assembly is arranged on the surface of the exhaust valve body; the anti-freezing assembly comprises a connecting pipe, the outlet end of the air outlet pipe is communicated with the connecting pipe, and spiral threads are formed on the inner surface of the connecting pipe; The utility model discloses a heating jacket, including exhaust valve body, heating jacket and heating controller, the base is installed to the up end of discharge valve body, the basin has been seted up to the inside of base, just the inside of basin has evenly seted up the several apopore down, the supporting seat is installed to the up end of base, the up end of supporting seat is provided with the heating jacket, be provided with nichrome wire in the cavity of the inside seting up of heating jacket, the inside embedding of heating jacket has the lag, the lag closely wrap up in the surface of connecting pipe, heating controller is all installed to the surface mounting of heating jacket has the dismantlement subassembly.
