Description
Technical field
The present invention relates to a kind of valve field, and in particular to a kind of draining valve.
Background technology
Original PM10050~250VT167-00 deck levels bleeder valve, it is the dress for ship deck emergency drainage
Put, open by operating handwheel, close valve passage, carry out drainage works.But its valve body material is ZG230 ~ 450 intolerant to sea
Aqueous corrosion, seal valve seat is inlayed easily to loosen with valve body for screw thread produces seepage, and sealing pair is that conical surface guiding inlays rubber ring, is closed
Rubber ring is yielding or pull by pressure during valve, and in ammunition store, in order to prevent the ammunition in ammunition store meet water by
Tide, the requirement for drainage system is very high, and manual unlocking valve carries out draining can not meet to require.
The content of the invention
To solve the above problems, the present invention provides a kind of self-closing non-return deck drainage emergency valve, have valve body, valve rod, flap,
Bonnet and handwheel, handwheel lower end are provided with a control stick, and control stick is provided with travel indicator and limits valve opening maximum row
The locating ring of journey；Control stick lower end is connected with valve rod, and the centre of valve rod is provided with extension bar, and valve rod both ends carry valve stem nut,
Valve stem nut is connected with fixed mount, and stroke showing rod is fixed with fixed mount, and unlatching is marked with the stroke showing rod and is closed
Close scale；Valve rod lower end is connected with flap, and flap uses bottom-open type conical surface floating flap, and flap bottom is provided with spring, valve rod
With being provided with grid above flap.The locating ring is integrally fixed on control stick with travel indicator, and locating ring plays limitation hand
The effect of rotational courses is taken turns, rotation hand wheel, when the travel indicator on control stick runs into locating ring, stop the rotation handwheel, this
It is openable to greatest extent for valve.
Extension bar among valve rod and valve rod is connected by pivot pin, or is connected by universal joint, can using this structure
Head will be manipulated and be arranged on the position of easily operated valve, or head will be manipulated and be positioned close to the lateral bulkhead of valve, saving cabin
Interior space.
Rubber seal ring pads are inlaid with bonnet, valve rod lower end is connected with flap, and the flap uses the bottom-open type conical surface
Float disc, flap bottom are provided with spring.Rotation hand wheel, the travel indicator of valve rod is allowed to point to the open and close quarter of showing rod
The centre position of degree, conical surface floating flap remain and are embedded in the rubber seal ring on bonnet under the elastic force effect of spring
Pad matches, linear sealing state, effectively prevent the water in valve body lower portion discharge pipe line or air can not on spill on deck
Face.When the depth of water is 120mm ~ 150mm in sump, the water gravity acted on flap overcomes the partial action of support spring
Power, flap is crack downwards to be opened, Auto-drainage.When moment, the depth of water reached 300mm, the water gravity acted on flap overcomes completely
Whole active forces of support spring, flap are all turned on downwards Quick drainage.Work of the flap in recoil of spring power after water emptying
It is coincide with lower reset with rubber seal ring pads, reaches Auto-drainage effect.
Valve body is made with bonnet of bronze ZCuSn10Zn2, strengthens the corrosion resistance to seawater.It is provided with above gully
Grid, grid are fixed on deck by welding seat board, and grid can prevent debris from blocking drainage channel.
The present invention can carry out Auto-drainage in the unmanned cabin maked an inspection tour, and strengthen security performance, sealing property is stable, corrosion resistant
Corrosion is strong, and service life is short.

Embodiment
This invention is described further with reference to accompanying drawing, a kind of self-closing non-return deck drainage is met an urgent need as shown in Figure 2,3, 4
Valve, there is valve body 1, valve rod 2, flap 3, handwheel 4 and bonnet 5, and handwheel lower end is connected with control stick 6, control stick lower end and the phase of valve rod 2
Connect, be additionally provided with locating ring 17 and travel indicator 7 on control stick, locating ring and travel indicator are all fixed on control stick.
The lower end of control stick 6 is connected with valve rod 2, is provided with extension bar 11 among valve rod 2, valve rod 2 is connected with extension bar 11 by pivot pin 12.
Valve rod both ends carry valve stem nut 9, and valve stem nut 9 dig-ins screw 18 by flush end of slotting and is connected with fixed mount 10, fixed mount 10
On be fixed with stroke showing rod 8, be marked with the stroke showing rod 8 unlatching, close scale.The lower end of valve rod 2 is connected with flap 3
Connect, flap 3 uses bottom-open type conical surface floating flap, and the bottom of flap 3 is provided with spring 15.
Using this structure of extension bar, handwheel can be arranged on to valve lateral position, the space saved in cabin.Valve body is deep
Enter gully, at the draining well head being fixed on by welding seat board 14 below deck, one is provided with the top of valve body and gully
Individual grid, the grid are fixed above deck by grille frame 16, and grid can prevent debris from blocking drainage channel.Bonnet 5
On be inlaid with rubber seal ring pads 19, strengthen sealing property.Valve body, flap, bonnet are made of bronze ZCuSn10Zn2, are had
Effect prevents seawater corrosion, improves anticorrosive property, increases the service life.
Embodiment 1
Manually operated valve, draining is carried out, turn handwheel counterclockwise, valve rod is descending by valve stem nut, promotes conical surface floating valve
Valve moves down, and now path opens draining.Dextrorotation is started to take turns, and valve rod is up by valve stem nut, pulls conical surface floating flap
Move up, now valve passage is closed, and the water or air in valve body lower portion pipeline are unable to overflow.
Embodiment 2
