But be subject to the complex effects of various sea situation, on the one hand, hull inevitably produces vibration (because of the pitching caused by wave and rolling), the air cylinder of store compressed rock gas will produce vertically to horizontal direction vibration, the upheaval of swing compound etc., on the other hand, confined space residing for air cylinder effectively ensure that the drying of gas storage bottle, if obturation effect is bad, then air cylinder makes moist, and not only shortens the working life of air cylinder, also brings dangerous hidden danger.
Summary of the invention
For solving the problem, the utility model devises a kind of deliver from vault sealing configuration of CNG cargo ship air cylinder, adopt and go out the technological scheme that sealing configuration is set between compartment and deliver from vault pipe on cabin hatchcover, achieve the sealing that deliver from vault pipe passes cabin hatchcover place, and deliver from vault pipe have swing and floating degrees of freedom.
The technical solution adopted in the utility model is, a kind of deliver from vault sealing configuration of CNG cargo ship air cylinder, described air cylinder is vertically arranged in sealed compartment, passes hatchcover by upper end plug assembly, key is: described upper end plug assembly is arranged positioning ring is convex, ring goes out compartment and arranges ring-type convex, is set with organ tubular type stuffing box gland, forms the sealing configuration flexibly connected at positioning ring between convex and ring-type convex.
In technique scheme, the outlet of air cylinder is provided with upper end plug assembly, upper end plug assembly comprises deliver from vault pipe, what hatchcover is preset with deliver from vault pipe passes goes out compartment, gas is delivered to cabin by deliver from vault pipe in air cylinder, the gap that go out compartment and deliver from vault pipe formation of sealing configuration provided by the utility model namely on plug hatch, structure comprises that positioning ring is convex, ring-type convex and one have flexible and flexible organ tubular type stuffing box gland, ring-type convex is welded on the circumference in hole on hatchcover, and deliver from vault pipe is through ring-type convex; The convex cover of positioning ring is welded on deliver from vault pipe, and stuffing box gland one end is locked on ring-type convex, the other end is locked on positioning ring is convex, by flexible sealing collar shape convex and positioning ring convex between form sealing configuration.
The beneficial effects of the utility model are: (1) sealing configuration provided by the utility model is easy for installation, and sealing effect is stable good; (2) in the technological scheme improved further, ring-type convex internal surface is provided with spacing between deliver from vault tube outer surface, when effectively ensure that running into greater impact air cylinder rocks or float on the one hand, deliver from vault pipe and air cylinder stable connection, also ensure that sealing effect on the other hand.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 of the present utility modelly faces structural representation;
In accompanying drawing, 1, positioning ring is convex, 2, stuffing box gland, 3, ring-type convex, 4, hatchcover, 5, deliver from vault pipe, 6, air cylinder, 7, go out compartment, 8, end plug body, 9, valve seat.
Embodiment
A kind of deliver from vault sealing configuration of CNG cargo ship air cylinder, described air cylinder 6 is vertically arranged in sealed compartment, passes hatchcover 4 by upper end plug assembly, described upper end plug assembly is arranged positioning ring is convex 1, ring goes out compartment 7 and arranges ring-type convex 3, between positioning ring convex 1 and ring-type convex 3, be set with organ tubular type stuffing box gland 2, form the sealing configuration flexibly connected.
The outlet of air cylinder 6 is provided with upper end plug assembly, upper end plug assembly comprises deliver from vault pipe 5, what hatchcover 4 is preset with deliver from vault pipe 5 passes goes out compartment 7, gas is delivered to cabin by deliver from vault pipe 5 in air cylinder 6, above-mentioned sealing configuration as shown in Figure 1, structure comprises that positioning ring is convex 1, ring-type convex 3 and one end is socketed in ring-type convex 3, the other end is socketed in stuffing box gland 2 on positioning ring convex 1, and ring-type convex 3 is welded on circumference hatchcover 4 going out compartment 7, and deliver from vault pipe 5 is through ring-type convex 3; Convex 1 cover of positioning ring is welded on deliver from vault pipe 5, and stuffing box gland 2 one end is locked on ring-type convex 3, the other end is locked on positioning ring convex 1, by flexible gland 2, forms sealing configuration between ring-type convex 3 and positioning ring convex 1; Stuffing box gland 2 is organ tubular type, centre is cavity, there is flexibility and elasticity, adapt to the height of CNG cargo ship cabin top different parts, when deliver from vault pipe, air cylinder pitch by hull vibrations generation, stuffing box gland 2 has flexible flexible degrees of freedom, and ensure that deliver from vault pipe 5 moves with air cylinder 6 and do not deviate from, sealing effect is stablized.
