Problems solved by technology

To achieve this purpose, it is usually necessary to determine which watertight valves (that is, butterfly valves with watertight function) to enter the fire damper system before ordering the fire damper from the manufacturer. Once the manufacturer completes the production of the fire damper, it cannot be modified.
In addition, the construction period of the ship is very short, and all the nodes of the ship are pushed out backwards. Determining the watertight valve entering the fire damper before the fire damper is formulated will prolong the ship construction period, which is not conducive to improving the production efficiency of the ship

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0023] Such as figure 1 As shown, in this embodiment, a method for realizing a watertight valve with a fire damper function according to the present invention includes the following steps:

[0024] Step S10: installing a watertight valve on the air duct of the bulkhead of the ship;

[0025] Step S20: Installing a fire detection device in the bypass pipeline of the watertight valve

[0026] Step S30: Connect the watertight valve to the fire detection device, and when the fire detection device detects a fire inside the ship, the watertight valve is automatically closed.

[0027] In the normal working state, the watertight valve is in an open state, and the fire detection device can be installed to detect the fire inside the ship. If the fire detection device detects a fire inside the ship, the water...

Abstract

A method for achieving a water-tight valve having a fireproof air damper function, comprising step S10, step S20 and step S30: step S10 comprises installing a water-tight valve in an air duct of the bulkhead of a ship; step S20 comprises disposing a fire detection device in a pipeline next to the valve of the water-tight valve; step S30 comprises connecting the water-tight valve to the fire detection device such that the water-tight valve automatically closes when the fire detection device detects that a fire is ignited at an inner portion of the ship. The present invention may guarantee that the water-tight valve has a fireproof air damper function when a fireproof air damper system of the ship has not been not entered. A water-tight valve system having a fireproof air damper function, comprising the water-tight valve of the method for achieving a water-tight valve having a fireproof air damper function, wherein the system may detect fires at the inner portion of the ship and may improve the safety of the ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method and system for realizing a watertight valve with the function of a fire damper. Background technique [0002] When the air duct passes through the watertight wall, the butterfly valve installed on the air duct needs to be both watertight and fireproof. The existing solution is to customize the watertight butterfly valve and add it to the ship's fire damper system to realize the function of the fire damper. To achieve this purpose, it is usually necessary to determine which watertight valves (that is, butterfly valves with watertight function) to enter the fire damper system before ordering the fire damper from the manufacturer. Once the manufacturer completes the production of the fire damper, it cannot be modified. In addition, the construction period of the ship is very short, and all the nodes of the ship are reversed. Determining the watertight valve entering the fire...
