Description

Water inlet valve for ship anti-breaking cabin

Technical Field

The utility model relates to a boats and ships prevent broken cabin water intaking valve.

Background

In the design process of ships, particularly passenger ships, due to the fact that influences on safety such as ship stability are considered, a plurality of systems such as ventilation systems need to guarantee bidirectional movement of gas and prevent liquid from flowing reversely, and pipeline arrangement requirements of the ventilation systems on the ships with small redundancy such as the passenger ships are extremely strict, and in order to guarantee that the ventilation pipelines are arranged simply, a plurality of ventilation pipes are not led to a watertight integrity V line and then reverse to a side, a ship anti-cabin-breaking water inlet valve is urgently needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a can guarantee the two-way circulation of air but prevent the valve of the reverse circulation of a large amount of water, a small amount of water can reverse circulation.

In order to solve the technical problem, the utility model discloses a prevent broken cabin water intaking valve, including import and export, still include:

the inlet cavity is communicated with the inlet;

an outlet chamber, the outlet communicating with the outlet chamber;

a communication port disposed between the inlet chamber and the outlet chamber;

a drain port provided at a bottom position of the outlet chamber;

a float ball disposed within the outlet chamber;

the outlet cavity is separated from the inlet cavity through a partition plate, and the outlet cavity is communicated with the inlet cavity only through the communication port and the discharge port.

Further, the density of the floating ball is smaller than that of water.

Furthermore, the floating ball type water heater also comprises a limiting block, wherein the floating ball is limited in a space surrounded by the limiting block and the partition plate and is positioned below the communicating port.

Further, the communication port is arranged at the top of the outlet cavity, and the floating ball is arranged below the communication port.

Further, the communication port further comprises a sealing gasket, and the sealing gasket is arranged on the periphery of the outlet below the communication port; when the outlet cavity water level rises, the floating ball floats, and the floating ball can be attached to the sealing gasket.

Further, the cross-sectional area of the vent is smaller than 710 mm.

Furthermore, the flow area of any position of the inlet cavity, the communication port and the outlet cavity is larger than the sectional area of the inlet and the outlet.

The utility model has the advantages that: the utility model discloses a broken cabin water intaking valve is prevented to boats and ships can make the ventilative pipeline arrange simpler, need not cause the pipeline to the topside again after the watertight integrality line more than, has less discharge outlet, and the condensed liquid can directly discharge through the discharge outlet of bottom when the outlet side has longer pipeline, can not block the valve.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model discloses a boats and ships prevent broken cabin water intaking valve prevents that broken cabin water intaking valve main part is inside to be divided into two parts of import chamber and outlet chamber, and the import chamber is with outlet chamber through the intercommunication mouth at top and the discharge mouth UNICOM of below, and wherein the discharge mouth of below requires flow area to be less than 710mm according to the standard, has floater and stopper in the outlet chamber, and the effect of stopper prevents that the floater from moving along with the air current direction. The anti-breaking cabin water inlet valve can ensure normal bidirectional air circulation in the pipe, and when water enters from the outlet end, a floating ball in the valve can float and block the inlet end; various forms such as flanges, welding and the like can be adopted to be connected with the pipeline; the inlet cavity is communicated with the outlet cavity through a communication port at the top, and a discharge port at the bottom of the outlet cavity is used for discharging a small amount of condensed liquid; the weight and the floating performance of the floating ball need to ensure that the outlet end pipeline can float when water enters, and the sealing gasket at the inlet can effectively seal with the floating ball and ensure the watertight performance of the floating ball; when the liquid at the outlet section is removed, the floating ball can fall in time so as not to block the inlet; a drain port with the sectional area smaller than 710mm is arranged at the bottom of the outlet end, so that the floating ball cannot float upwards when the outlet end pipeline forms condensed liquid; the flow areas of any positions of the inlet cavity, the top communication port and the outlet cavity are larger than the sectional areas of the inlet and the outlet; the exit need set up the stopper, prevents that the floater from along with the flow direction displacement.

The actual working flow of the valve is as follows:

gas or fluid can flow to the export through the import during normal work, when being used for gaseous medium, if contain the steam of easily condensing in the gaseous medium, if export section pipeline is longer, the liquid of condensing in the pipeline can discharge to the import pipeline through the escape opening of bottom in the valve in, when the liquid that flows in reverse direction appears, the internal floating ball of valve body can float and form closed fluid along this direction with the UNICOM mouth at top owing to receiving buoyancy and flow, only can flow to the entrance point through the escape opening of bottom, because the flow area of escape opening is less than 710mm, the regulation permits.
