Embodiment Construction

[0023] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0024] like Figure 1 to Figure 2 As shown, a marine hydraulic damping water hammer reduction valve of the present invention includes a horizontal housing 2, and the left part of the housing 2 is provided with a horizontal cylindrical first piston chamber whose left end communicates with the outside world; the right side of the housing 2 There is a horizontal cylindrical second piston chamber whose right end communicates with the outside world; the first piston chamber and the second piston chamber are separated by a piston chamber partition, and a piston rod passage port is opened on the piston chamber partition; the casing 2 The left end is connected to the external pipeline through the butt flange 1, and the right end of the housing 2 is sealed by the cover 8;

[0025] The inner wall of the first piston chamber is closely attached to a...

Abstract

The invention discloses a marine hydraulic damping type water hammer reduction valve, and relates to the field of shipbuilding. The water hammer reduction valve comprises a horizontal shell, the left part of the shell is provided with a first piston cavity, and the right part of the shell is provided with a second piston cavity; a first piston is arranged on the inner side wall of the first piston cavity, a second piston is arranged on the inner side wall of the second piston cavity, and the first piston and the second piston are connected through a horizontal piston rod; a pressure spring is arranged between a piston cavity partition plate and the first piston; the left end and the right end of the inner side wall of the second piston cavity communicate through a first oil pipeline and a second oil pipeline, a first one-way valve from right to left is arranged on the first oil pipeline, and a first one-way valve from left to right is arranged on the second oil pipeline; and hydraulic oil is arranged in the second piston cavity. Due to the fact that the hydraulic damping principle is adopted, large water hammer pressure can be borne, and the effect of protecting the pipeline is achieved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a marine hydraulic damping water hammer reduction valve. Background technique [0002] The role of pipelines in shipbuilding is very important, but there is not much protection for pipelines and valves. Water hammer phenomenon is easy to appear in the construction of large ships, and the damage of water hammer to ship pipelines is very serious. Existing water hammer elimination equipment is basically used in fire-fighting and drinking water in buildings on land, and is mainly divided into inflatable type and rubber type. These two types of devices have certain defects. The inflatable type elimination device needs to regularly check whether the inflation pressure is sufficient, if the pressure drops or is insufficient, it will not be able to play a protective role, and this situation is very dangerous under such severe working conditions on ships. The rubber type is made of elastic a...
