Description
Technical field
This utility model relates to a kind of valve, particularly relates to a kind of manual hull valve of copper alloy with double sealing structure.
Background technology
Manual hull valve is applied to naval vessel pipeline through the side of a ship side of resistance to laminate, is in cabin the of pipeline and outboard UNICOM
One locking, internal circulation medium is sea water, fresh water and oil.
Hull valve of the prior art is usually and is made up of main parts size such as actuator, valve rod, valve body, valve discs.Work as hands
Wheel turns clockwise, and makes valve rod rotate by screw thread pair and rises mobile until driving valve disc to rise valve closing, now valve
The medium power of inlet channel is conducive to the sealing of valve, and the sealing of the biggest valve of valve inlet pressure is the best.When the handwheel inverse time
Pin rotates, and makes valve rod rotate decline and promotes valve disc to move down until being opened by valve, the now medium power of valve inlet runner
Power needed for being unfavorable for the unlatching of valve, valve inlet, the outlet the biggest then valve opening of pressure reduction is the biggest, and this is current existing structure
The shortcoming of valve.As valve aperture relatively big (inside nominal diameter ＞ 80mm), valve opening can be caused extremely difficult, even occur to beat
The not phenomenon of valve opening door.
Solution heavy caliber copper alloy manual hull valve unlatching moment is big, manipulation this problem of difficulty, is urgent need in this area
The big technical problem solved.
Summary of the invention
The purpose of this utility model is to provide a kind of manual hull valve of copper alloy rational in infrastructure, good seal performance, its fall
Low valve opening moment, saves bypass valve simultaneously and reduces the volume of valve, also has energy-saving safe, decreases loine pressure and damage
Lose, improve the feature of security of system.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
The manual hull valve of copper alloy, it includes valve body, valve disc, valve rod, valve disc lid, handwheel, and wherein valve disc is set in valve rod
Bottom, the upper end of valve disc is provided with and seals greatly bulge loop, and the big upper surface sealing bulge loop is big sealing surface, and the lower end of valve disc is arranged
Having little sealing bulge loop, the lower surface of little sealing bulge loop is primary sealing surface.
The above-mentioned big internal diameter sealing bulge loop is 128mm, and external diameter is 143mm.
The above-mentioned big height sealing bulge loop is 3mm.
The internal diameter of above-mentioned little sealing bulge loop is 46mm, and external diameter is 52mm.
The height of above-mentioned little sealing bulge loop is 3mm.
Above-mentioned valve body, valve rod and handwheel fasten and connect, and are provided with big split annulus and little in the valve disc lid of valve disc upper end
Split annulus.
Owing to using technique scheme so that this utility model has following features and an effect:
This utility model utilizes valve disc primary sealing surface first to open the valve disc pass solving the manual hull valve of heavy caliber copper alloy
The unlatching difficult problem caused owing to valve inlet outlet pressure differential is excessive when closing, reduces valve opening moment, beneficially valve
Open, save bypass valve simultaneously and reduce the volume of valve, light weight；It also has rational in infrastructure, good seal performance, safety joint
Pressure loss in piping, the feature of raising security of system, can be reduced.
Accompanying drawing explanation
Fig. 1 is copper alloy of the present utility model manual hull valve structural representation.
Fig. 2 is the structure for amplifying schematic diagram of the valve disc in Fig. 1.
In figure, 1, valve body, 2, valve disc, 3, valve rod, 4, valve disc lid, 5, little split annulus, 6, big split annulus, 7, handwheel,
8, bulge loop is sealed greatly, 9, little sealing bulge loop.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.Following example are only tool of the present utility model
Body embodiment, but design concept of the present utility model is not limited thereto, all utilizes this design that this utility model is carried out non-solid
The change of matter, all should belong to the behavior invading this utility model protection domain.
As depicted in figs. 1 and 2, the manual hull valve of this utility model copper alloy, its structure is as follows: it is by valve body 1, valve disc
2, valve rod 3, valve disc lid 4, handwheel 7 form, and valve body 1, valve rod 3 and handwheel 7 fasten and connect, and arrange in the valve disc lid 4 of valve disc 2 upper end
Having little split annulus 5 and big split annulus 6, valve disc 2 is set in the bottom of valve rod 3, and the upper end of valve disc 2 is provided with and seals greatly bulge loop
8, the big upper surface sealing bulge loop 8 is big sealing surface, and the lower end of valve disc 2 is provided with little sealing bulge loop 9, little sealing bulge loop 9 times
End face is primary sealing surface.The big internal diameter sealing bulge loop 8 is 128mm, and external diameter is 143mm, and the big height sealing bulge loop 8 is 3mm.Little
The internal diameter sealing bulge loop 9 is 46mm, and external diameter is 52mm, and the height of little sealing bulge loop 9 is 3mm.
Operation principle of the present utility model is as follows:
When handwheel turns clockwise, make valve rod rotate by screw thread pair and ramp up mobile until driving valve disc to rise valve
Large and small sealing surface on dish simultaneously closes off, and now the medium power of valve inlet runner is conducive to the sealing of valve, valve inlet pressure
The sealing of the biggest valve of power is the best.When handwheel rotates counterclockwise, valve rod rotates to decline first to be opened the primary sealing surface that valve disc is
Medium turns on, and rear big sealing surface is opened by medium power, until can use little force square to continue valve opening when valve pre-post difference is the least,
Realize full flow to open, valve is fully opened.
