Abstract

The invention discloses a one-way exhaust valve. The exhaust valve comprises a valve body, a sealed tank, springs, a seal ring, a main exhaust valve, a sealed pipe and exhaust valve bodies. The one-way exhaust valve is provided with a pressure exhaust device in the valve body. The pressure exhaust device is connected with the seal ring through the springs arranged on the sealed tank. The springs are stressed to achieve sealing performance. The situation that an existing device is sealed through gravity is avoided. The one-way exhaust valve is further provided with the sealed pipe. The four ormore exhaust valve bodies are arranged in the sealed pipe to form a multilayer sealing structure. The one-way exhaust valve achieves the multiple sealing effect through the two sets of the exhaust valve bodies. The one-way exhaust valve greatly improves the sealing effect and is wide in application range.

Description

technical field [0001] The invention belongs to a sealing device, in particular to a one-way exhaust valve. Background technique [0002] There are many types and uses of one-way exhaust valves according to different sealing requirements. The common ones include one-way exhaust valves made of metal and one-way exhaust valves made of plastic. For example, metal materials are generally used for gas transportation pipes. Way, a vent valve made of plastic is used for the vent holes on the coffee bags. [0003] The one-way exhaust valve can only discharge outward, while the breathing valve is bidirectional. When the system pressure is high, it will discharge outward, and when the system pressure is low, it will inhale. Generally, the valve cover is provided with a central through hole, one end is a joint, and the other end extends into the valve body cavity and is provided with one or more ventilation grooves at its end. The existing device also utilizes the effect of sealing g...
