The filling sealing device greatly prolongs service life and further lowers operation cost.
Description
Technical field
The present invention relates to sealing arrangement, refer in particular to a kind of volatile liquid filling and sealing device that in container, uses during the can volatile liquid.
Background technology
When in various container, injecting volatile liquid, to leak because of the volatile gas that gasification produces for avoiding volatile liquid, pollution and the influence to keeping the safety in production to environment generally all will seal the filling exit of container.The encapsulating method that adopts at present is that the plain seal of container tank saliva is a radial seal, is side seal at jar mouth inner wall sealing perhaps, and perhaps the wedging formula sealing of jar mouth is the axial line contact, is single mode and seals, and it is single to exist sealing surface, is prone to shortcomings such as inefficacy.
Summary of the invention
The objective of the invention is to improve and innovate to shortcoming that exists in the background technology and problem, provide a kind of radial and axial implementation simultaneously to seal, sealing effectiveness is failure-free volatile liquid filling and sealing device more.
The objective of the invention is to construct a kind of sealing arrangement that is arranged at tank body inlet place, comprise gasbag seat and the actuating unit that is arranged on the gasbag seat external diameter, wherein:
Actuating unit comprises the permanent seat that is fixed on gasbag seat top by nut and screw rod; Be fixed on the pressure bladder pressed seat of gasbag seat bottom by push bolt; And be connected the pressure bladder on permanent seat and the pressure bladder pressed seat; And pressure bladder and gasbag seat sidewall are provided with inflating cavity, and wherein the pressure bladder radial face contacts with tank body inlet lateral extent eaves and constitutes radial seal, and pressure bladder axial vane surface inflation contacts with tank body inlet inwall and constitutes side seal;
Described gasbag seat is a T type seat, and the gasbag seat middle part is provided with hydraulic pipe, and gasbag seat top one side is provided with the air inlet pipe ozzle, and air inlet pipe ozzle and inflating cavity perforation.
The present invention has the following advantages and beneficial effect:
The present invention has been owing to adopted radial-axial compound seal mode, make original single sealing (axially or radially) under the situation that does not increase additional function, realize both direction in sealing, and because bag material is an elastic body; So less demanding to canned degree of lip-rounding shape of container and roughness, in the scope that is no more than the air bag distortion, all can be with the alteration of form of jar mouth; And carry out the failure-free sealing, because air bag is when actuating unit is out of service, just begin the sealing that puts on the air; So do not have relative motion between air bag and jar mouth, so prolong greatly the service life of sealing device, the cost of operation and expense will further reduce; Adopted two way seal simultaneously; After place seal failure, can not cause gas leakage, all favourable to site environment and production safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a running condition structural representation of the present invention.
The specific embodiment
Can know that by Fig. 1,2 the present invention is arranged at tank body inlet place, comprise gasbag seat 5 and the actuating unit that is arranged on gasbag seat 5 external diameters, wherein:
Actuating unit comprises the permanent seat 6 that is fixed on gasbag seat 5 tops by nut 3 and screw rod 4; Be fixed on the pressure bladder pressed seat 9 of gasbag seat 5 bottoms by push bolt 8; And be connected the pressure bladder 7 on permanent seat 6 and the pressure bladder pressed seat 9; And pressure bladder 7 is provided with inflating cavity 12 with gasbag seat 5 sidewalls; Wherein pressure bladder 7 radial faces 10 contact with tank body inlet lateral extent eaves and constitute radial seal, and pressure bladder 7 axial vane surfaces 11 inflations contact with tank body inlet inwall and constitute side seal;
Described gasbag seat 5 is a T type seat, and gasbag seat 5 middle parts are provided with hydraulic pipe 13, and gasbag seat 5 tops one side is provided with air inlet pipe ozzle 1, and air inlet pipe ozzle 1 connects with inflating cavity 12.
Structural principle of the present invention:
Air inlet pipe ozzle 1 of the present invention is installed on the gasbag seat 5; On gasbag seat 5, be processed with screw 3; Be used for being connected with actuating unit, screw rod 4 is connected with permanent seat 6, and pressure bladder 7 is processed by elastomeric material; The screw rod 4 and the permanent seat 6 that when pressure bladder is made, will connect as one are placed in one, and form a fixed connection.For guaranteeing that failure-free connects, on permanent seat 6, be processed with semi-circular recesses, be processed with protruding arc groove on the pressure bladder 7 and be complementary simultaneously with groove on the air sac sealing seat 5.Pressure bladder 7 is fixed in gasbag seat 5 tops through screw rod 4 by nut 3." ┣ " shape structure is processed in pressure bladder 7 bottoms, and is complementary with gasbag seat 5 and pressure bladder pressed seat 9, and by push bolt 8 pressure bladder pressed seat 9 is connected with gasbag seat 5, and the seal receptacle bottom is fixed in pressure bladder 7 bottoms.
Principle of work of the present invention:
The present invention is when carrying out the operation of effumability filling liquid; The present invention is delivered to the container tank mouth; Because this assembly dia is the T type greater than container tank mouth and this device, the device bottom can get in jar mouth smoothly, and top then contacts with the container tank mouth and stops descending; Because this device has certain pressure, so the T type plane of pressure bladder and container tank interruption-forming face seal are radial seal.After face seal forms; Through the air inlet pipe ozzle pressurized air is sent into by in the inflating cavity that forms between gasbag seat and the pressure bladder, because gasbag seat is a rigid body, under compressed-air actuated effect; Pressure bladder begins to expand; It is big that diameter constantly becomes, until with jar mouth inwall combine closely formation sealing surface, i.e. side seal.In the can operation process, liquid is through in the hydraulic pipe inflow container, and the volatile gas of generation is discharged collection owing to there is the pressure bladder sealing can not leak but pass through gas piping.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention, engineering staff make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention; The technology contents that the present invention asks for protection all is documented in claims.
