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] like 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 watertig...

Abstract

The invention discloses an implementation method for a watertight valve with the fire damper function. The method comprises the steps that S10 the watertight valve is arranged on an air hose at a bulkhead of a ship; S20, a fire detection device is arranged in a valve bypass pipeline of the watertight valve; and S30, the watertight valve is connected to the fire detection device, and when the firedetection device detects that the interior of the ship is on fire, the watertight valve is automatically closed. The method has the advantage that when the watertight valve does not enter a fire damper system of the ship, the fire damper function can be achieved. The invention further provides a watertight valve system with the fire damper function. The watertight valve system comprises the watertight valve in the implementation method for the watertight valve with the fire damper function and has the advantages that fire detection can be carried out on the interior of the ship, and the safetyof the ship can be improved.

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...
