Abstract
The utility model discloses a formula that opens ice oil hold breather valve, including valve body, valve gap, pull ring and induction port dustcoat, be equipped with spring, pressure valve disc and pressure disk seat in the valve body, be equipped with valve rod and guide arm in the valve gap, valve gap and valve body fixed connection, the both ends of valve rod respectively with pull ring and pressure valve disc fixed connection, be equipped with bush and adjusting collar on the valve rod, the adjusting collar passes through the sealing washer and is connected with stem seal. This formula that opens ice oil hold breather valve, through the threshold value that the fixed valve door was established to the handle, when the elasticity of oil hold internal pressure above the spring, the pressure valve disc of interlock originally opens, efflux of gas in the oil hold to reduce the oil hold internal pressure. The filter screen is set up at the gas outlet, volatile oil gas can be adsorbed to the loss that oil volatilizees and brings has been reduced. The setting of pull ring is used for the initiative pressure release of oil hold to emit under -deck crude oil.
Description
Technical field
Relate to this utility model ship equipment technical field, specially one open ice formula cargo tank breather valve.
Background technology
Cargo tank wall and the deck of general tanker (as a example by accounting for most of oil carrier) can only be born not
The pressure of superatmospheric about 0.25 × 100000Pa, if it exceeds this pressure, hull will be damaged
Or deformation.And liquid goods expands with heat and contract with cold；If volatile liquid, also can constantly evaporate thus not
Disconnected pressurization.Breather valve is a kind of automatic respiration device, its effect be in cabin pressure reach certain numerical value with
When being above in overvoltage condition, gas is discharged in air；When pressure drops to the negative pressure of below certain numerical value
During state, air can be drawn in cabin again, thus prevent hull from sustaining damage, adjust pressure in cabin,
Liquid goods damage is avoided to lose.Breather valve is also referred to as P/V valve or pressure/vacuum, and breather valve mainly has gravity type and work
Plug (spring) formula two kinds.
Utility model content
The purpose of this utility model is to provide one to open ice formula cargo tank breather valve, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, this utility model provide following technical scheme: one open ice formula cargo tank breathe
Valve, including valve body, valve gap, draw ring and air entry outer housing, is provided with spring, pressure valve disc in described valve body
With pressure valve seat；Being provided with valve rod and guide rod in described valve gap, valve gap is fixedly connected with the valve body；Described valve rod
Two ends fixing with draw ring and pressure valve disc is respectively connected, valve rod is provided with lining and regulation set, and regulation is overlapped
It is connected with valve stem seal by sealing ring；Described pressure valve disc is fixedly connected on pressure valve seat, pressure valve
Dish connects axostylus axostyle by cam, and axostylus axostyle is fixedly connected with handle；Described regulation set is by sealing ring and valve
Lid is tightly connected；Described guide rod is fixing with dish on spring to be connected；Be provided with in described air entry outer housing screen cover,
Filter screen and vacuum valve seat；Being provided with steel wire in described screen cover, vacuum valve seat is provided with vacuum valve disc.
Preferably, described valve body and valve gap are connected by screw and nut, are provided with pad between screw and nut
Circle.
Preferably, described draw ring and valve rod are connected by screw and nut, and screw and nut is provided with opening
Pin.
Preferably, described both ends of the spring connects dish and pressure valve disc on spring, and pressure valve disc is provided with two,
It is mutually twisted between pressure valve disc.
Compared with prior art, the beneficial effects of the utility model are:
Originally the formula that opens ice cargo tank breather valve, sets the threshold value of valve, when in cargo tank, pressure exceedes bullet by handle
The elastic force of spring, the pressure valve disc of occlusion opens originally, and in cargo tank, gas flows out, thus it is intrinsic pressure to reduce cargo tank
Power.Filter screen is set in gas outlet, it is possible to the oil gas of absorption volatilization, thus reduces what oil volatilization brought
Loss.The active pressure release being provided for cargo tank of draw ring, thus crude oil in cabin is released.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: one opens ice formula cargo tank breather valve,
Including valve body 1, valve gap 2, draw ring 5 and air entry outer housing 14, in valve body 1, it is provided with spring 11, pressure
Valve disc 12 and pressure valve seat 13, valve body 1 and valve gap 2 are connected by screw and nut, screw and nut it
Between be provided with packing ring, spring 11 two ends connect dish 10 and pressure valve disc 12 on spring, and pressure valve disc 12 is provided with
Two, it is mutually twisted between pressure valve disc 12, the active pressure release being provided for cargo tank of draw ring 5, thus
Crude oil in cabin is released；Being provided with valve rod 6 and guide rod 9 in valve gap 2, what guide rod 9 and valve gap 2 were offered is deep
Groove engagement connects, and guide rod 9 can slide in deep trouth；Valve gap 2 is fixing with valve body 1 to be connected；Valve rod 6
Two ends are fixed be connected with draw rings 5 and pressure valve disc 12 respectively, and valve rod 6 is provided with lining 4 and regulation set 7,
