Abstract

The invention discloses a valve capable of preventing water hammer effect, comprising a valve main body, the inner cavity of the valve main body is fixedly connected with a sealing support sleeve, the left side of the valve main body is connected with a water inlet pipe, and the valve main body The right side communicates with a water outlet pipe, and the inner cavity of the valve body is provided with a movable plate, and a water permeable hole is opened on the top of the movable plate. The present invention is provided with a sealing support sleeve, a movable plate, a water permeable hole, a connecting rod, a mounting plate, a main body of a spoiler rod, a connecting plate, a first telescopic rod, a movable push rod, a movable rod, a connecting lifting plate, a fixed plate, and a second telescopic rod. The combination of the rod and the controller has the advantages of anti-hammer effect and long service life, which solves the problem that the existing valves usually do not have a spoiler rod, which cannot avoid the occurrence of water hammer effect, and the water hammer effect will affect the waterway access. The damage to the pipeline will reduce the service life of the water access pipeline.

Description

technical field [0001] The invention relates to the technical field of valves, belongs to IPC classification F16K, and specifically relates to a valve capable of preventing water hammer effect. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have quite a variety of varieties and specifications. During the use of the valve, water hammer effect often occurs when the valve is opened or closed. The existing technology generally uses bypass to absorb water hammer when eliminating the water hammer effect. The method of energy is an after-event remedial measure after the water hammer effect occurs. It cannot avoid the occurrence of t...
