Abstract
The invention discloses a front supporting structure of a horizontal liquefied gas bottle for a vehicle. The front supporting structure comprises an outer front sealing head of a gas bottle shell, an inner front sealing head of a gas bottle container and an inner supporting pipe penetrating through the outer front sealing head and the inner front sealing head, wherein a distribution head is fixedly arranged at one end of the outer front sealing head on the inner supporting pipe; the other end of the inner supporting pipe is provided with a butt-joint flange; an outer supporting pipe is sleeved on the inner supporting pipe; one end of the outer supporting pipe penetrates out of the inner front sealing head and is fixedly connected with inner front sealing head; the other end of the outer supporting pipe is fixedly connected with the butt-joint flange; and a supporting ring is arranged between the inner supporting pipe and the outer supporting pipe. By using the structure disclosed by the invention, the strength of the horizontal bottle for the vehicle is increased, the heat conduction amount is reduced, the heat insulation effect is increased, and the stability of the pressure in the bottle is ensured.
Description
Technical field
The present invention relates to a kind of front support structure of horizontal Vehicular liquefied gas cylinder.
Background technique
Horizontal Vehicular liquefied gas cylinder is to be used for storing cryogenic liquide, mainly comprises LNG Liquefied natural gas, liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide etc.This type of bottle is made up of inner bag and shell, and the interlayer between inner bag and the shell is pumped into high vacuum, and inner bag is connected with the back support structure through the front support structure with shell.
Front support mainly is to be used for being connected between interior front head and the outer front head, and traditional front support structure join strength and heat conduction amount are difficult to guarantee simultaneously.(λ is the thermal conductivity of stainless steel material by leaking hot formula Q=λ F △ T/L; F is that tube section is long-pending, and L is a length of tube) learn that Lou heat is directly proportional with tube section is long-pending, owing to need to guarantee the intensity of front support structure; So the sectional area of used support tube is bigger; Cause heat conduction amount bigger, influence the heat insulation effect of liquified petroleum gas cylinder, make boost in the liquified petroleum gas cylinder very fast.
Summary of the invention
Technical problem to be solved by this invention is: the front support structure that the horizontal Vehicular liquefied gas cylinder that a kind of intensity is high, insulation effect is good is provided.
For addressing the above problem; The technological scheme that the present invention adopts is: the front support structure of horizontal Vehicular liquefied gas cylinder, comprise outer front head, the cylinder liner of gas cylinder shell interior front head, be located in the interior support tube in outer front head and the interior front head, an end that is positioned at outer front head on the interior support tube is set with distributing head; The other end of support tube is provided with abutted flange in said; Be arranged with outer support tube on the support tube in said, outer support tube one end passes interior front head, and is fixedly connected with interior front head; The other end of outer support tube is fixedly connected with abutted flange, also is provided with support ring in the position of interior front head between said interior support tube and the outer support tube.
Be provided with the molecular sieve bag that abutted flange and outer support tube are surrounded in said on the front head, the molecular sieve bag comprises cylindrical shell, end socket and is filled in cylindrical shell and molecular sieve that end socket is interior.
The centre of support tube and outer support tube outer wall is respectively arranged with annular skiving groove in described.
In said on the front head outside support tube around be provided with the stiffening plate of annular.
Be provided with installation step near interior front head place in the said outer support tube, said support ring is arranged on the installation step, and said outer support tube end is provided with the fixed plate that is used for fixing support ring.
Said support ring is the glass fibre reinforced plastics support ring.
The invention has the beneficial effects as follows: increased the intensity of horizontal car bottle, reduced heat conduction amount, increased its insulation effect, guaranteed that pressure of the inside of a bottle is stable.
Description of drawings
Fig. 1 is the schematic representation of the front support structure of horizontal Vehicular liquefied gas cylinder.
Among the figure: 1. outer front head, 2. in front head, 3. stiffening plate, 4. abutted flange, 5. support ring, 6. distributing head, 7. in support tube, 8. fixed plate, 9. outer support tube, 10. molecular sieve bag, 101. cylindrical shells, 102. end sockets, 103. molecular sieves.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further specified.
As shown in Figure 1; The front support structure of horizontal Vehicular liquefied gas cylinder; Comprise: comprise outer front head 1, the cylinder liner of gas cylinder shell interior front head 2, be located in the interior support tube 7 in outer front head 1 and the interior front head 2, an end that is positioned at outer front head 1 on the interior support tube 7 is set with distributing head 6, the other end of interior support tube 7 is provided with abutted flange 4; Be arranged with outer support tube 9 on the interior support tube 7; Outer support tube 9 one ends pass interior front head 2, and are fixedly connected with interior front head 2, on the interior front head 2 outside support tube 9 around be provided with the annular stiffening plate 3.The centre of interior support tube 7 and outer support tube 9 outer walls is respectively arranged with annular skiving groove.The other end of outer support tube 9 is fixedly connected with abutted flange 4; Be provided with installation step near interior front head 2 places in the outer support tube 9; Position at interior front head 2 also is provided with glass fibre reinforced plastics support ring 5 on outer support tube 9 installation steps and between the interior support tube 7, and outer support tube 9 ends are provided with the fixed plate 8 that is used for fixing support ring 5.
Also be provided with the molecular sieve bag 10 that abutted flange 4 and outer support tube 9 are surrounded on the interior front head 2, molecular sieve bag 10 comprises cylindrical shell 101, end socket 102 and is filled in cylindrical shell 101 and molecular sieve 103 that end socket 102 is interior.
Because the other end of interior support tube 7 is provided with abutted flange 4; Be arranged with outer support tube 9 on the interior support tube 7, outer support tube 9 one ends pass interior front head 2, and are fixedly connected with interior front head 2; On the interior front head 2 outside support tube 9 around be provided with stiffening plate 8; Strengthen through glass fibre reinforced plastics support ring 5 between outer support tube 9 and interior support tube 7 interlayers, not only guaranteed intensity, also reduced hot transmission.
(λ is the thermal conductivity of stainless steel material by leaking hot formula Q=λ F △ T/L; F is that tube section is long-pending, and L is a length of tube) learn that Lou heat is directly proportional with tube section is long-pending, so adopted the skiving processing in the middle of interior support tube 7 and the outer support tube 9; Both guaranteed the intensity that two ends connect; Reduce the area of middle heat transfer again, reduced leaking heat, guaranteed bottle pressure stability for a long time.
