Multilayer diversion waterproof hammer high-positioning vent valve

Abstract

The invention discloses a multilayer diversion waterproof hammer high-positioning vent valve, and relates to the field of valves. The vent valve is designed mainly aiming at solving the problem that afloating ball of an existing vent valve is poor in positioning. The vent valve comprises a lower valve body and an upper valve body, a hole and a guide rod installing through hole are formed in a guide rod support at the top of the lower valve body, a guide rod stretches into the guide rod installing through hole, a valve plate is arranged at the lower end of the guide rod, a hole is formed in the valve plate, and the guide rod is sleeved with a spring; a hole is formed in a lower guide base in the upper valve body, a lower guide cover is arranged at the portion, in a lower positioning rod installing through hole, of the bottom of the lower guide base, a lower positioning rod is located in the lower guide cover, the floating ball is fixed to the top of the lower positioning rod, and an upper positioning rod is arranged at the top of the floating ball; a valve lid is installed at the top of the upper valve body, a vent opening is formed in the valve id, a sealing ring is arranged at the vent opening, an upper guide base is connected with the valve lid, an upper guide cover is arranged at the portion, in an upper positioning rod installing through hole, of the upper guide base, andthe upper positioning rod stretches into the upper guide cover. The vent valve has the advantages that the floating ball can be guided, and the sealing effect is guaranteed.

Description

Technical field: [0001] The invention relates to the field of valves, in particular to an exhaust valve installed on a water delivery pipeline. Background technique: [0002] The floating ball of the existing exhaust valve installed on the water pipeline is placed in the valve body, and the positioning of the floating ball is poor. When the water pressure entering the valve body is low, the floating ball will float away from the exhaust port, resulting in The exhaust port is not completely closed, and water leaks. In addition, the existing exhaust valve is prone to water hammer. Invention content: [0003] The technical problem to be solved by the present invention is to provide a multi-layer diversion water hammer high positioning exhaust valve with good positioning of the floating ball, which can completely close the exhaust port and prevent water leakage. [0004] The above purpose is achieved in this way: it includes a lower valve body, the top of the lower valve bod...
