Technical Field
The utility model relates to a rubber lip formula airtight type lobe sealing device mainly is applied to the gas seal and the water-stop field between the naval vessel cabin, and gas or the sea water between the adjacent cabin of separation flow each other.
Background
The traditional bulkhead end face sealing device mainly has a water-resisting function, prevents seawater from leaking to other cabins from one cabin when the cabin is damaged and leaks water accidentally, reduces loss and influence of a ship in an accidental emergency, and has no function of isolating gas.
Traditional bulkhead end face sealing device mainly comprises parts such as casing, apron, sealing ring, O shape sealing washer, adopts the sealed principle of floating ring, and when no water entered, the membrane dish rotated with shafting synchronous, and the membrane dish can be automatically looked for well, realizes no power loss dry run. When water enters and reaches a certain water pressure, the membrane disc can be attached to one side of the shell and is in a static (sealing) state and does not rotate along with the shafting. A small gap is reserved between the inner ring surface of the membrane disc and the shaft, floating sealing is achieved, and the whole sealing of the device is achieved by matching with an O-shaped sealing ring. But gas sealing cannot be achieved.
Disclosure of Invention
The utility model aims at overcoming the above-mentioned not enough, providing a rubber lip formula airtight type lobe sealing device, possessing the isolation function of sea water and gas between the cabin simultaneously, strengthened the security of naval vessel under unexpected emergency. The sealing device has the characteristics of good sealing performance, strong shock resistance, strong displacement compensation capability and the like.
According to the technical scheme provided by the utility model, rubber lip formula airtight type lobe sealing device, a serial communication port, including casing, apron, staple bolt, sealing ring and O shape sealing washer, the sealing ring has two, and the sealing ring cover is established epaxially, the outside at the sealing ring is established to the staple bolt, the casing cover is in the outside of sealing ring, and the sealing ring is connected with the casing and is personally submitted lip formula structure, the bilateral symmetry of casing is equipped with two apron, the apron is connected with the casing, the top of casing is equipped with the water inlet, the bottom of casing is equipped with the delivery port.
As a further improvement, the main body part of the cover plate adopts a half-structure design, the half surface adopts pin positioning and bolt connection, and the back is connected into a whole.
As a further improvement of the utility model, the cover plate is fastened with the shell through bolts.
As a further improvement of the utility model, an O-shaped sealing ring is arranged between the cover plate and the shell.
As a further improvement of the utility model, the shell is made of seawater corrosion resistant bronze alloy material.
As a further improvement of the utility model, the cover plate is made of seawater corrosion resistant bronze alloy material.
As a further improvement, the sealing ring is made of wear-resistant nitrile rubber.
Compared with the prior art, the utility model, have following advantage:
the utility model discloses an airtight type lobe end face seal device can realize the isolation of sea water and gas between the naval vessel cabin, has increased gas seal's function on traditional lobe end face seal device basis, has expanded the function and the range of application of product.
Drawings
Fig. 1 is a cross-sectional view of the overall structure of the present invention.
Description of reference numerals: the device comprises a shell 1, a cover plate 2, a hoop 3, a sealing ring 4, an O-shaped sealing ring 5, a mounting screw 6, a shaft 7, a water inlet 8 and a water outlet 9.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
As shown in the figure, airtight type bulkhead sealing device of rubber lip formula, including casing 1, apron 2, staple bolt 3, sealing ring 4 and O shape sealing washer 5, sealing ring 4 has two, and the cover is established on axle 7 after sealing ring 4 rises to rise, staple bolt 3 establishes the outside at sealing ring 4, casing 1 overlaps in the outside of sealing ring 4, and sealing ring 4 personally submits lip formula structure with casing 1's connection, casing 1's bilateral symmetry is equipped with two apron 2, pass through bolt-up between apron 2 and the casing 1, sealing ring 4's lip and apron laminating, the rubber lip receives certain predeformation, and the deflection is about 1-2mm, and the trailing flank of sealing ring 4 contacts with casing 1's boss. After the whole device is installed, the sealing ring 4 is limited in a cavity formed between the cover plate 2 and the shell 1, a water inlet 8 is formed in the top of the shell 1, a water outlet 9 is formed in the bottom of the shell 1, the shell is fixed on a bulkhead through a mounting screw 6, cooling water flows in from the water inlet 8 and flows out from the water outlet 9, certain water pressure is kept inside the device, and the functions of lubricating, cooling and increasing the water pressure of the end face of the device are achieved on the friction end face of the device.
The main body part of the cover plate 2 adopts a half structure design, and the half surface is positioned by a pin and connected by a bolt and then is connected into a whole.
The cover plate 2 and the shell 1 are fastened through bolts.
An O-shaped sealing ring is arranged between the cover plate 3 and the shell 1, so that static sealing between the parts is realized.
The shell 1 is made of a seawater corrosion resistant bronze alloy material; the cover plate 2 is made of corrosion-resistant stainless steel material; the sealing ring 4 is made of wear-resistant nitrile rubber materials, and can meet the requirement of water lubrication friction sealing for ships.
The working principle of the utility model is as follows:
as shown in the above figure, the device is designed to adopt a bilateral symmetrical end face sealing structure, the inside of the device is filled with (circulating) cooling water, the upper end of the device enters the device, the lower end of the device flows out, a certain water pressure is kept, under the combined action of the pretightening force of the rubber lip and the water pressure, when the shaft 7 rotates, the sealing ring is tightly attached to the cover plate to form a water lubrication end face sealing friction pair, the end face water sealing is realized, and the gas or seawater between adjacent cabins is blocked from flowing mutually.
When the shaft 7 generates the play, enough clearance is reserved between the shaft 7 and the cover plate 2 and between the sealing ring 4 and the shell 1 in the radial direction, and the rigid collision is prevented. In the axial direction, when the shaft 7 moves, the sealing ring 4 performs sliding compensation on the shaft 7, and the phenomenon of blocking cannot occur.
