Abstract
The utility model relates to a ship division end face sealing device, which is used for watertight seal among shafting division cabins of various ships. A casing is connected with a ship bulkhead, a diaphragm disc is driven by a retainer ring fixedly connected onto a shaft so as to rotate along with the shaft synchronously, and two end faces of the diaphragm disc and two end faces of the inner side of the casing form a sealing friction pair with a watertight seal function. When a cabin on any of two sides of the bulkhead is in water seepage, one end face of the diaphragm disc is closely attached onto one end face in the casing under thrust action of water pressure, so that water is isolated automatically and avoids flowing into another cabin. Since an O-shaped sealing ring in a groove of the diaphragm disc can not slide relative to the surface of the shaft, abrasion of the O-shaped sealing ring is reduced, service life of the O-shaped sealing ring is prolonged, and sealing performance of the sealing device is improved. The casing, the diaphragm disc and the retainer ring are all in half structure, thereby bringing convenience to emergency maintenance and replacement for ships in navigation. In addition, the ship division end face sealing device is compact in structure, reliable in sealing and long in service life.
Description
Technical field
The utility model relates to a kind of boats and ships separation face seals, is used for the water-stop between all kinds of marine shaftings cabin.
Background technology
As the separation face seals, under the situation of boats and ships boundary bulkhead both sides arbitrary cabin water inlet, all should be able to play the water-stop effect, stop water to enter another cabin.
Existing separation face seals, membranous disc is sleeved on the axle, by the water-stop between realization membranous disc of the O-ring seals in the membranous disc groove and the axle surface; Membranous disc is adjacent to its end face and housing inner side end under the thrust of boundary bulkhead either side hydraulic pressure, stops water to flow to the boundary bulkhead opposite side by the end clearance automatically, thereby realizes the water-stop of axle system between the boats and ships separation chamber.Since membranous disc (together with the O-ring seals in the groove) with spool between only depend on self mutual force of sliding friction to keep transmission of power, in course of normal operation because of the variation of transmitted power or the effect of inertia of membranous disc, to make continually between membranous disc (together with the O-ring seals in the groove) and the axle surface and produce slide relative, cause the rapid wearing of O-ring seals, finally make device loss of seal function.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of novel membranous disc power transmission structure is provided, and avoids membranous disc (together with the O-ring seals in the groove) to produce slide relative and cause wearing and tearing with the axle surface in operation process.
Main solution of the present utility model is achieved in that
Housing connects with cabin wall, collar connects firmly on axle by bolt, the membranous disc (together with the O-ring seals in the groove) that is sleeved on the axle rotates with axle synchronously by the collar drive, and the membranous disc both ends of the surface can form the sealing friction pair with water-stop function with the inboard both ends of the surface of housing respectively.When the water inlet of arbitrary cabin, boundary bulkhead both sides, a side of membranous disc under the thrust of hydraulic pressure with housing in a side end face be adjacent to, isolated water flows to another cabin automatically.Because membranous disc is done to rotate synchronously with axle, do not produce slide relative between membranous disc (together with the O-ring seals in the groove) and the axle surface, reduced the wearing and tearing of O-ring seals, prolonged service life, improved the sealing property of device.Described housing, membranous disc and collar all adopt Hough formula structure, are connected as one by bolt and taper pin, are convenient to boats and ships emergency maintenance and replacing under the boat state.
The utility model compared with prior art has the following advantages:
The utility model is applicable to the separation sealing of all kinds of marine shaftings, adopts novel membranous disc power transmission structure, can avoid membranous disc (together with the O-ring seals in the groove) to produce slide relative and cause wearing and tearing with the axle surface in operation process.Compact conformation, reliable, the long service life of sealing.

The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, the utility model is made up of housing 1, collar 2, membranous disc 3, nylon jacket 4, straight pin 5, O-ring seals 6 and parts such as some bolts, pin.Housing 1 connects with boundary bulkhead by screw, is evenly equipped with the pit that matches with straight pin 5 on the membranous disc 3 one end end faces, respectively is provided with nylon jacket 4 in the pit.Adopt O-ring seals 6 to carry out water-stop between membranous disc 3 and the axle surface, O-ring seals 6 is installed in the groove of membranous disc 3.Membranous disc 3 (together with the O-ring seals in the groove 6) is sleeved on the axle, the collar 2 that connects firmly on axle rotates with axle synchronously by straight pin 5 drive membranous discs 3 (together with the O-ring seals in the groove 6), avoided sliding mutually between membranous disc 3 (together with the O-ring seals in the groove 6) and the axle surface, the wearing and tearing of O-ring seals 6 have been reduced, prolong the service life of O-ring seals 6, improved the sealing property of device.When the water inlet of arbitrary cabin, separation both sides, under the thrust of hydraulic pressure, the end face of membranous disc 3 and housing 1 inner end surface are adjacent to, isolated water flows to another cabin automatically.Nylon jacket 4 is used to protect membranous disc 3 not worn and torn by straight pin 5.Housing 1, collar 2, membranous disc 3 all adopt Hough formula structure, connect for whole by screw and pin, are convenient to the fault emergency maintenance and the part replacement of equipment in the ship's navigation process.Housing 1 and collar 2 adopt yorcalnic, tin bronze, albronze or cast steel material to make, and membranous disc 3 adopts filling tetrafluoro or elastomeric material to make.
As accompanying drawing 2 and shown in Figure 3, be the parts mounting structure scheme drawing of collar in the utility model 2.Collar 2 adopts the Hough formula, by screw it is fixed on the axle.Collar 2 circumferential uniform being fastened with are no less than 4 straight pins 5, are used to drive membranous disc 3 (together with the O-ring seals in the groove 6) and rotate synchronously with axle.
