Description
Technical Field
The utility model relates to the technical field of valves, particularly, relate to an automatic exhaust valve.
Background
The automatic exhaust valve is used for exhausting, when the system is filled with water, gas in the water continuously escapes to the highest position due to temperature and pressure changes and gathers, when the gas pressure is greater than the system pressure, the buoy falls down to drive the valve rod to move downwards, the valve port is opened, and the gas is continuously exhausted. When the gas pressure is lower than the system pressure, the float bowl rises to drive the valve rod to move upwards, and the valve port is closed. Automatic discharge valve is exactly like this continuous circulation and carries out work, but in long-term use, discharge valve's exhaust duct gas outlet and valve rod can be corroded and rusted, the condition of adhesion probably takes place, leads to the unable normal opening of discharge valve to exhaust, consequently, how to avoid the emergence of above condition, reduces discharge valve fault rate, guarantees that discharge valve normally exhausts, is the technical problem that needs the solution.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the technical problem that exists among prior art or the correlation technique at least, disclose an automatic exhaust valve, can prevent that discharge valve's exhaust duct gas outlet from rustting with the valve rod and taking place the adhesion and leading to the emergence of the unable normal condition of opening of discharge valve in long-term use, reduce discharge valve's fault rate, guarantee that discharge valve normally exhausts.
The utility model discloses a following scheme realizes: an automatic exhaust valve comprising: the exhaust valve comprises a valve body, a valve rod, a floating ball, an exhaust pipe and a spring, wherein a valve cavity is arranged in the valve body, the floating ball is arranged in the valve cavity, the floating ball is fixedly connected with the valve rod, the exhaust pipe is arranged in the valve body, one end of the spring is fixedly connected with the valve rod, the other end of the spring is fixedly connected with the exhaust pipe, and the valve rod and the exhaust pipe are both nested in the spring.
According to the utility model discloses an automatic exhaust valve, preferably, the blast pipe surface is provided with first spring mounting bracket, and the valve rod surface is provided with second spring mounting bracket, and the one end fixed connection of spring is on first spring mounting bracket, and the other end fixed connection of spring is on second spring mounting bracket.
According to the utility model discloses an automatic exhaust valve, preferably, the spring surface is provided with corrosion-resistant layer.
According to the utility model discloses an automatic exhaust valve, preferably, the one end welding of spring is on first spring mounting frame, and the other end welding of spring is on second spring welding frame.
The beneficial effects of the utility model include at least: the valve cavity is arranged in the valve body, the floating ball is arranged in the valve cavity and fixedly connected with the valve rod, the exhaust pipe is arranged in the valve body, one end of the spring is fixedly connected with the valve rod, the other end of the spring is fixedly connected with the exhaust pipe, the valve rod and the exhaust pipe are all embedded in the spring, and the situation that the exhaust valve cannot be normally opened due to the fact that the gas outlet of an exhaust pipeline of the exhaust valve is rusted and adhered to the valve rod in long-term use can be prevented.
