Description
Technical field
The utility model belongs to marine machinery field, and in particular to a kind of New Marine self-closing flat valve.
Background technology
On ship, particularly Large Container Ship, two deck aisle are longer, need to arrange multiple bilge wells.Bilge well pressure
Carry bilge-water to release to topside by gravity, according to load line convention, pipeline of releasing herein need to be disposed with check device, such as scheme
1, check-valves is added using conventional stop valve（Screw down nonreturn valve water (flow) direction should be low in and high out, it is impossible to applied to herein）, no
Only increase valve member quantity, and due to valve member oneself height, bilge-water can not release totally completely.
For the more ship in some complicated cabins, it is often necessary to which some cabin bilge-water is released, and another is set
The cabin of bilge well.Bilge-water is equally existed using conventional stop valve not release completely, and shut-off fitting is forgotten there is also crewman
May, cause UNICOM of Liang Ge closed in space.
Utility model content
For problems of the prior art, the utility model provides a kind of New Marine self-closing flat valve, makes dirt
While bilge-water is released completely in well, when crewman's not operated valve member, realize that valve member is closed automatically, isolation two spaces
Purpose.
To achieve the above object, the utility model uses following technical scheme：
A kind of New Marine self-closing flat valve, the flat valve include seat board, body, valve disc, soket head cap screw, valve rod,
Bushing, handle, spring, nut, packing ring and bolt, are closely connected between the body and valve disc, between the body and valve rod
Connected by soket head cap screw, the body between nut, packing ring and bolt and seat board by being connected, and the packing ring is set in
On bolt, bolts and nuts threaded connection, the spring be arranged between bushing and valve disc, the handle be arranged on valve rod top
End, is threadedly coupled between valve rod and handle.
Pad is provided between the body and seat board, is threadedly coupled between body and seat board and pad is set, so kept away
Exempt from the zinc layers of destruction pipe and hull paint during later stage installation, also improve segmentation prepackage integrality.
O-ring is provided between the body and valve disc, is sealed using O-ring, O-ring fixing bolt so that is changed
O-ring more facilitates.
The spring bottom is provided with several steel balls.
If valve member is arranged in bilge well and shaft length is more than 1 meter, support bar, the support are provided with valve rod
Bar between bushing and valve rod by being vertically connected, and bushing can be slided up and down and rotated on valve rod, can be according to reality during in-site installation
The height of border situation regulation support bar and direction.
Compared with prior art, the beneficial effects of the utility model are：1. the utility model makes bilge-water in bilge well complete
While releasing entirely, when crewman's not operated valve member, realize that valve member is closed automatically, reach the purpose of isolation two spaces；2. tie
Structure is simple, manufacturing cost is low, reasonable in design.

Embodiment
With reference to implementation example and accompanying drawing, the utility model is described in further detail, but it is new that this practicality should not be limited with this
The protection domain of type.
As shown in Figures 2 and 3, the present embodiment New Marine self-closing flat valve, the flat valve includes seat board 1, body 3, valve
Disk 5, soket head cap screw 6, valve rod 8, bushing 9, handle 11, spring 12, nut 13, packing ring 14 and bolt 15, the body 3 and valve
Closely connect, connected between the body 3 and valve rod 8 by soket head cap screw 6 between disk 5, the body 3 by nut 13,
It is connected between packing ring 14 and bolt 15 and seat board 1, the packing ring 14 is set on bolt 15, bolt 15 connects with the screw thread of nut 13
Connect, the spring 12 is arranged between bushing 9 and valve disc 5, the handle 11 is arranged on the top of valve rod 8, valve rod 8 and handle 11
Between be threadedly coupled.
Preferably, being provided with pad 2 between the present embodiment body 3 and seat board 1.
As further preferred, O-ring 4 is provided between the present embodiment body 3 and valve disc 5.
As further preferred, the bottom of the present embodiment spring 12 is provided with several steel balls 7.
As still more preferably, the present embodiment valve rod 8 is provided with support bar 10, the support bar 10 by bushing 9 with
It is vertically connected between valve rod 8.
The present embodiment seat board 1 welds together with Ship Structure 16.
Under usual state, because of spring squeezing action, valve disc is in close contact with valve body, plays cut-off effect.Valve disc and valve
Body is sealed using O-ring, employs O-ring fixing bolt so that replacement o circle more facilitates.
Ship Structure needs advance perforate, and bore size should 30 ~ 40mm bigger than valve body size, reserved space of freezing enough.
When the present embodiment is installed, valve rod need to be taken apart with valve disc, the upper plate of bilge well 17 opens one in advance can pass through valve rod 8
Aperture, valve rod pass through aperture after, with valve disc reconnect.Handle 11 is placed on outside bilge well.When valve member need to be opened, upwards
Pull-up handle compression spring, makes valve disc depart from valve body, and handle, valve disc, when valve member needs to close, slowly unclamp in pipeline UNICOM
It is in close contact under the action of the spring with body, realizes and close, particularly Large Container Ship, two deck aisle 18 are longer, is needed
Arrange multiple bilge wells 17；If bilge well 17 is located in ballast tank 19, to reach PSPC requirements（The special sea of all types ship
Water Ballast cabin and the double topside place protective coating performance standards of bulk freighter）, seat board and valve body can be installed in different phase.
In the piping of segmentation makes, seat board is zinc-plated after being welded in advance with shipyard pipe（It should be noted protection seat board screw thread）, make same
Part carries out live prepackage.Valve body, to be threadedly coupled, thus is avoided that the zinc layers and ship of destruction pipe when the later stage installs with seat board
Body is painted, and also improves segmentation prepackage integrality.
If valve member is arranged in bilge well and shaft length is more than 1 meter, support bar can be increased, pass through bushing and valve
Bar is connected.Bushing can be slided up and down and rotated on valve rod, can adjust the height of support bar during in-site installation according to actual conditions
And direction.
Although above-described embodiment makes specific descriptions to the utility model, for one of ordinary skill in the art
For, it is understood that can not depart within spirit and scope of the present utility model be based on the utility model disclosed in
Appearance is modified or improved, and these modification and improvement are all within spirit and scope of the present utility model.
