Description
Affiliated technical field
The utility model relates to boats and ships and ocean engineering manufacturing technology field, relates in particular to a kind of float-ball self-closing discharge valve that is used for the pipeline venting system.
Technical background
Naval Architecture and Ocean Engineering design and building, all closed in space all will arrange permeability cell, are used for that the cabin loads and the airiness of row when carrying.According to code requirement, permeability cell will be arranged in the vertex in cabin, also is in order to utilize volume of compartment more fully, because when the mouth of pipe is breathed freely in load medium (oil, water etc.) submergence, and the continuation loading, medium will be emerged from the air head on the deck by permeability cell.Permeability cell to be arranged in sometimes web beam below, the web beam size on the ship is generally all very big, so the height H of permeability cell end-to-end distance from the deck can reach 500mm even 1000mm sometimes.The ventilative mouth of pipe in the cabin to the space between the deck (volume of compartment) just can not be utilized.Particularly owing to be subjected to some underdeck strong structure influences, the meeting that permeability cell is arranged is very low, and Sun Shi volume of compartment is just very big like this, is unacceptable sometimes, as shown in Figure 1.If permeability cell upwards turns round after entering the cabin, as shown in Figure 2, the ventilative mouth of pipe can remain into 50～100mm apart from cabin flying deck distance H 1, and volume of compartment just can be fully utilized." U " type about but permeability cell does not allow under the normal circumstances is curved, can stockpile medium, and influence is ventilative.
The utility model content
The purpose of this utility model provides a kind of float-ball self-closing discharge valve, this valve is installed on the permeability cell of cabin, thereby raise the ventilative height of the mouth of pipe in the cabin,, also seek a kind of new terms of settlement to the layout of the ventilative pipeline in cabin so that utilize volume of compartment more fully.
In order to achieve the above object, the technical solution of the utility model is as follows: a kind of float-ball self-closing discharge valve, comprise valve body part, ball float part, with the permeability cell connecting bridge.The valve body part is made up of base plate a1, coverboard a2, flange a3, back seal pad a4 four parts; The ball float part is made up of ball float b1, lower seal pad b2, welded nut b3, screw b4 and cover plate b5 five parts; Form by lower flange c1, short tube c2, upper flange c3 and following bolt and nut c4, last bolt and nut c5 with the permeability cell connecting bridge.Welded nut b3 is welded on the center of ball float b1 upper surface, lower seal pad b2 is pressed on the upper surface of ball float b1 with the cover plate b5 of screw b4 and stainless steel material, after ball float is partly assembled and is finished, in the cavity that the valve body part of packing into is made up of base plate a1 and coverboard a2, base plate a1 has the liquid manhole appendix, be used for liquid in the cabin enter with the emptying valve body in liquid, coverboard a2 bottom also is provided with liquid turnover aperture, can quicken the discharging of residual liquid in the valve body; Install and the permeability cell connecting bridge then, be provided with back seal pad a4 between flange a3 and the lower flange c1, flange a3 is connected by following bolt and nut c4 with lower flange c1, communicate with the cavity that the valve body part is made up of base plate a1 and coverboard a2 with the short tube c2 of permeability cell connecting bridge, short tube c2 is connected with last bolt and nut c5 by upper flange c3 with permeability cell arm 7 simultaneously.
A kind of float-ball self-closing discharge valve is applied to the ventilative pipeline system in cabin, concrete scheme is: do one section lengthening permeability cell 6 earlier, and upwards turn round, nadir below permeability cell is made a permeability cell arm 7 then, permeability cell arm 7 has the flange that is complementary with float-ball self-closing discharge valve upper flange c3, uses bolt and nut c5 the float-ball self-closing discharge valve installation is fastened on the permeability cell arm 7.
Principle of work of the present utility model is: the normal condition ball float sinks, and valve open if in the permeability cell water, wet goods medium are arranged, will flow in the cabin; When liquid tank loaded, along with liquid level in the cabin rises, liquid is the submergence ball float gradually, the ball float come-up, and lower seal pad b2 above it and valve body part back seal pad a4 combine closely, i.e. valve-off, the ball float submergence is big more, and buoyancy is big more, valve closing tight more.Loading work can be performed until liquid level near ventilative mouth of pipe place, ventilative can proceeding by " U " type is curved.When profit cabin row is carried,, make hydrops in the permeability cell if owing to reasons such as boats and ships rock, reduce with liquid level in the cabin, the buoyancy that ball float is subjected to is more and more littler, adds the pressure of the interior hydrops of permeability cell to ball float, ball float descends, and the hydrops in the valve open, permeability cell will flow in the cabin.
The beneficial effects of the utility model are: in light weight, easy for installation, this float-ball self-closing discharge valve is installed on permeability cell, improve the ventilative height of the mouth of pipe in the cabin, guarantee the cabin air permeable effect, improve the volume of compartment degree of utilization, being furnished with of ship's space permeability cell carried be total to good selection scheme.
