Abstract
Disclosed is a hook-type locking and sealing device for recovering tank-truck oil gas. Currently, a hemispherical device is mostly utilized at home and abroad to hermetically recover the oil gas generated by tank-truck oil, and due to large size of the hemispherical device, interference can be generated with a breather valve of a tank-truck cover, and the recovery rate is low. The hook-type locking and sealing device for recovering tank-truck oil gas comprises a sealing cover (1) arranged on lower portion thereof, a rubber conical cylinder (3) is arranged in the middle portion of the sealing cover, an elastic pull rod (4) penetrates through the sealing cover and the rubber conical cylinder and is connected with a connecting support (5), the connecting support is fixed on a loading arm flange, a sealing element (7) is arranged below the sealing cover which is provided with threaded locking hooks (2) and an air duct hose (6), and the threaded locking hooks are distributed uniformly in three-point mode. The hook-type locking and sealing device for recovering tank-truck oil gas is applicable to tank-truck oil gas recovery units.
Description
Technical field:
The tank wagon oil gas that the oil gas that
the utility model is produced when relating to a kind of oil depot to vapour (bavin) oil dress tank wagon reclaims reclaims the locking and closed device of hook-type.
Background technology:
are present, and the home and abroad adopts the semisphere device to carry out airtight recovery to the oil gas that the tank wagon charge of oil produces more, because volume is big, interfere with the generation of tank car lid breathing valve, and the percent recovery is low.
Summary of the invention:
The purpose of
the utility model provides a kind of being installed in and uses the percent recovery high, pollution-free on the loading arm, and the tank wagon oil gas that meets national security requirement reclaims the locking and closed device of hook-type.
Above-mentioned purpose realizes through following technical scheme:
a kind of tank wagon oil gas reclaims the locking and closed device of hook-type; Its composition comprises: be installed in the sealing lid that tank wagon oil gas reclaims the locking and closed device of hook-type below; Described sealing lid middle part is gone up the rubber cone tube is installed; Elastic draw bar passes described sealing lid and described rubber cone tube, and described elastic draw bar connects support, and described support is fixed on the loading arm flange; Packing element is equipped with in described sealing lid below, and described sealing lid is equipped with and is 3 screw-threaded coupling hook and soft air-guide pipes that are uniformly distributed with.
described tank wagon oil gas reclaims the locking and closed device of hook-type, and described sealing lid is at described elastic draw bar effect lower swing, and described screw-threaded coupling hook satisfies jar locking requirement of interior oil-air pressure.
described tank wagon oil gas reclaims the locking and closed device of hook-type, and described packing element and described rubber cone tube are processed by leading static, oil resistant, low temperature material.
Beneficial effect:
1. the utility model through the screw-threaded coupling hook will seal lid, packing element is pressed on the tank wagon jar mouth, realizes airtight charge of oil; The oil gas of discharging in the charge of oil process flows into gas recovery system for oil through soft air-guide pipe.
in view of the characteristics of China tank wagon jar flap dress breathing valve and pipeline, the circular slab construction of the sealing lid of the utility model, and it is little to take up room, and avoids breathing valve and pipeline, realizes effectively sealing.
The screw-threaded coupling hook of
the utility model is at 3 and is uniformly distributed with, and screw-threaded coupling power satisfies the requirement of pressing in the oil gas.
according to the out-of-level characteristics in tank wagon jar mouth plane, the sealing lid of this product is realized swing under the effect of elastic draw bar, and a packing element and a jar mouthful no gap are compressed, and avoids oil gas to leak.
Packing element of
the utility model and rubber cone tube are processed by leading static, oil resistant, low temperature resistant elastomeric material, have strengthened sealing effectiveness and safety effect.
The soft air-guide pipe of
the utility model has flexible and crooked function, can satisfy oil filling riser rotation and the needs of forced stroke of tank wagon in the stop scope.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is that the A-A of accompanying drawing 1 is to view.
The specific embodiment:
Embodiment 1:
a kind of tank wagon oil gas reclaims the locking and closed device of hook-type; Its composition comprises: be installed in the sealing lid 1 that tank wagon oil gas reclaims the locking and closed device of hook-type below; Described sealing lid middle part is gone up rubber cone tube 3 is installed; Elastic draw bar 4 passes described sealing lid and described rubber cone tube, and described elastic draw bar connects support 5, and described support is fixed on the loading arm flange; Packing element 7 is equipped with in described sealing lid below, and described sealing lid is equipped with and is 3 screw-threaded coupling hooks that are uniformly distributed with 2 and soft air-guide pipe 6.
Embodiment 2:
Embodiment 3:
The described tank wagon oil gas of
embodiment 1 reclaims the locking and closed device of hook-type, and described packing element and described rubber cone tube are processed by leading static, oil resistant, low temperature material.
Embodiment 4:
Embodiment 5:
