Decomposing, and more specifically, relating to a valve member assembly for a gas storage assembly, which has a primary assembly in addition to a main body containing a valve member. a housing, wherein the secondary housing houses a safety valve that discharges the overpressure gas to the outside, and the primary and secondary housings are securely mounted to the mounting cap. L·iltr 'Ji 15 Description of Related Art 100021 A conventional gas storage tank is filled with a substance (liquid or gas) sealed with an exhaust gas. When needed, the substance is released to the outside of the tank by the pressure of the exhaust gas. [〇〇〇3] The exhaust gas is usually liquefied petroleum gas, DME, chlorofluorocarbon 20 gas, CG2, nitrogen or oxygen. Gas storage tanks using exhaust gas include mobile butane storage tanks, insecticide tanks, hair styling tanks, portable fire extinguishers, etc. σ _4] When such a gas storage tank is placed at a relatively high temperature or pressure, its internal pressure accumulation causes it to deform or damage the tank. 5 1294021 丨005] For example, if the gas storage tank is directly exposed to sunlight for a long period of time, the contents of the gas storage tank will be heated and expanded by sunlight. Excessive accumulation of this pressure can cause the tank to decompose. 5

The article I have a miscellaneous I _] as shown in Figures 2 to 5 'in accordance with the first and other embodiments of the present invention - the gas cartridge-in-piece assembly i contains: _ main casing H)' It is fixed to the lower end of the erecting cap 3; the valve member trunk I is elastically supported inside the main casing 1; a opening and closing seal 40 is sandwiched between the main casing Between the body 1〇 and the erecting cap 3; the secondary casing 5〇, which is mounted to one side of the main casing 1〇; and the safety valve 6〇, which is installed in the secondary The housing is like the inside. _] As shown in Figs. 2, 4 and 5, the above-mentioned main casing is formed into an elbow shape, and a main gas passage (10) is formed therein. The space lla is formed in a vertical portion u to mount the &quot;the sash member body 20 therein, and a horizontal portion 12 extends horizontally from the bottom of the vertical portion 11. Here, the main gas passage 1a is formed from the space ua through the fourth end of the vertical portion 11 through the water (4) &gt; The top end of the vertical portion 11 is inserted and fixed to the attachment groove 3a formed at the central lower end portion of the erecting cap 3. 】 ★ As shown in the 3®, the bottom of the erecting cap 3 has a pair of notches 3b, which are connected to each other across the attachment groove 3a, and are placed opposite each other. The 11 1294021 vertical portion 11 of the housing ι is formed to extend horizontally, and the remainder-to-positioning recess 3b is disposed to properly set the secondary housing. [0037] The periphery of the d vertical portion u is in contact with the bottom of the erecting cap 3, and the moving resistance is horizontally from the main housing 155 15 20 - in contrast to the secondary housing 5G The direction extension (4) is free of vertical movement of the primary and secondary housings 10 and 50 produced by a compression spring 62 (which will be described later) in an Angkor valve 60. (4) The dry body guide m is radially protruded from the inner wall of the space iu and vertically formed to guide the lifting action of the valve member body 20 and formed - for flowing gas through the main gas passage Pathway. The lower end portion of the inner portion of the air M 11a is formed by a radially protruding spring guiding rib # llc' which is used to avoid the axial movement of the spring 30 (to be later) Described), and along the dry body guide lib, a path for providing gas flow is formed. [〇〇39] Here, the spring guiding rib lle will extend inwardly in the space 11a further than the trunk guiding member lib. 100401 h Illustrated in Figures 2 and 5, the above-described valve member trunk 20 has a central portion of the central bottom portion through which the cap body 3 is mounted and a lower end portion is formed in the vertical portion of the main casing 1G. The spring 3 in the space 11a of 11 is elastically supported. - The gas passage 20a is formed at the upper end portion of the valve member trunk 2 - the inner portion of the annular groove inner constricted portion is formed purely outside thereof, and 2 is formed horizontally at the center of the inwardly constricted portion 20b. 12 1294021 [0041] Meanwhile, the above-described opening and hermetic seal 40 are disposed in the attachment groove 3a of the erecting cap 3, and are disposed between the top end of the main casing 1 and the erecting cap 3. A through hole 4A is formed in the center of the seal 40 for the valve member body 2 to pass through. In the absence of the incoming/outflow of the gas, the inner circumference of the seal 4 is inserted into the contracted portion 20b to block the orifice 2〇c and prevent the gas from flowing in/out. [〇〇42] In order to cause the rolling body to flow in or out, the valve member body 2〇 is pressed. Then, the inner circumference thereof is forced out from the valve member body 20 to open the orifice 20c to allow the gas to be discharged to the outside, or to be filled into the tank body 2 through the valve member body 2〇. [_] As shown in Figures 2 and 4 and 5 and 6, the above-mentioned human body 50 and the main casing 1 are made of synthetic resin, and can be integrally formed by injection molding. form. A connecting rib 7 is formed between the secondary housing 50 and the main housing 1 to connect between and provide support.

The IUU 44J 20 is an overpressure gas passage 5A for discharging an overpressure gas, which is formed in the secondary casing 5G. The lower end of the overpressure gas passage 5a is integrally formed with the horizontal (four) 该 of the main casing 1 to connect the bypass gas passage 5Ga with the main gas passage iGa. Specifically, the lower end of the secondary casing 5 is integrally formed integrally with the outer circumference of the horizontal portion 12 of the main casing to form an excess gas inlet 12a within the main gas passage. The gas that has passed through the gas will be imported through the gas. 13 1294021 _6] Here, the discharge end of the overpressure gas inlet 12a is pressed against the bottom of the sealing member 61 made of rubber (which will be later described by the talented field) Field&quot; At the time of the overpressure gas inlet l2a, the airtight flange m is convexly formed to prevent the overpressure gas from entering the secondary casing 50. _7] When the secondary casing 5 is mounted, the upper end portion thereof is installed to be in communication with the gas discharge hole 3c at the lower end portion of the erecting cap 3. 10 15 20 , [_] - a compression spring maintaining plate 63 (described in the job) is inserted into the upper end portion of the secondary casing 5G, and the "maintenance projection member 51" is convexly formed to avoid the The compression spring maintains the movement of the plate 63. [0049] When the sealing member 61, the compression spring q and the compression spring dimension 63 are sequentially inserted into the secondary housing %, even if the compression spring 62 is in the compression spring maintenance plate 1 The second eye produces a thrust in the direction of the top end of the secondary casing 5〇. The compressed meal-free maintaining plate 63 may not move because the projection member 5 is maintained. _〇1 Therefore, the compression spring maintaining plate 63 is maintained by the sustaining projection member, and the sealing member 61 and the compression spring 62 can be easily broken into the secondary casing 5〇, and the gasket Μ It can be easily installed without being affected by the compression bomb 62. [〇〇51] A plurality of seal guides 52 are formed under the support protrusions 51, and the flanges are convexly protruded to guide the lift-up effect of the seal pair member 14 1294040 (will be slightly This is described later and forms the passage for receiving an overpressure gas flow from the main gas passage 10a of the primary casing 1〇. 2 and 5 and 7, the safety valve 6 () is installed inside the secondary housing 50, and it will open when the pressure inside the groove body 2 exceeds the pressure value of H疋, and will It is turned off when the pressure is lower than a predetermined pressure value. Installed in the secondary housing 50, and 1安全53] the safety valve 10 15 20 and includes: a sealing member 6 for opening and closing the overpressure gas into the σ 12a'-compression spring 62, which is mounted inside the secondary housing 50 such that its lower end is mounted relative to the sealing member 61; a pressure-spring plate 63 that is purely mounted within the secondary housing % It is desirable to retract the spring 62 and form a hole 在 in its central portion; and a sealing 塾 64 that maintains a seal between the secondary housing 50 and the erecting cap 3 (the sealing 塾64 has a lower end portion inserted into the top end of the secondary housing 50, a top end portion for pressing the bottom surface of the mounting cap body 3, and a hole (4) formed at the center to connect the (4) gas outlet 3e (4) The hole 63a) of the compressed elastic plate 63 is maintained.

[〇054] Here, the sealing member 61 has a flat bottom surface and a convex solid (four) on the top end surface thereof. The bottom (four) of the retractable bomb I Q is inserted around the outer portion of the rim portion and supported by the basin to prevent the compression spring 6 compressed along its length from being transversely deformed. Tomb 15 1294021 [0055] As shown in the figure , ^, the lower end portion of the compression spring 62 will widen the outer periphery of the fixed portion 61a of the enclosing member #61 and press a plurality of bullets *urerator 6ib to be radially The formation is formed to avoid lateral movement of the compression spring 62. 5

10 [嶋] the compression spring maintaining plate 63 is opposite to the lower end portion of the pressure-sensitive dense material 64 by the compressed elastic phthalocyanine, and lifts the sealing member H when the force exceeds a predetermined level in the groove body 2, And when the pressure is lower than the level, the (four) _ spring 再次 is again supported. [ ] 亥 也 Also the gasket 64 will seal between the secondary casing 5 〇 and the frame of the X towel body 3 (the air) from the inside of the groove body 2 from the 忒 secondary casing 5 The space between the crucible and the erecting cap 3 leaks out. The seal #64 has a _ airtight flange for sealing the dust gas out of the π 3e at its upper end portion, and is inserted into a maintaining portion formed on the upper end portion of the secondary casing 50. Outer 15 within the edge 50b

The surface has a first rolling seal 64c' to seal the gasket "and the secondary casing 50. [The surface] the insertion hole 63b for inserting the lower end portion of the sealing jaw 64 is attached to the shrinkage spring The upper end portion of the maintaining plate 63 is formed, and (d) the hole 20 in the central portion of the compression spring maintaining plate 63 is connected to the hole 6乜 formed in the central portion of the gasket 64. [REDACTED] The compression spring maintaining plate The 63 series is formed on the circumference so as to become gradually narrow toward the bottom, so that it can be easily inserted into the secondary casing 50 and easily passed through the sustaining projection member 51. Further, the gasket 64 is passed through After the sustaining projection member 51, the upper end portion 16 1294021 is blocked by the maintaining projection member 51 to prevent it from slipping through the open top end portion of the secondary housing 50. [0〇6〇] According to the present invention The first specific example of the valve member assembly of a gas storage tank will be described in detail. 5 [〇061] First, the procedure for discharging or sealing gas from the inside of the tank body 2 will be described. Stored in the trough body 2 The gas discharge _ to the outside, the valve member body 20 is pressed as shown in Fig. 6. Then the spring 3 () which has elastically supported the valve member trunk 2 is compressed, and 10 the valve member is dried The body 2() is simultaneously lowered to open the orifice 20c closed by the seal 40. [0063] When the orifice 20c is thereby opened, the gas stored in the tank body 2 flows through The main gas passage 20a and the space 11a in the main casing, and the orifice 20c formed in the valve member trunk 2〇15 and the gas passage 20a are discharged to the outside. • [0064] When no longer When it is required to use the gas in the gas storage tank and the force applied to the valve member body 20 is removed, the restoring force of the spring 3〇 causes the valve member body 20 to return to its original position and the Sealing 4〇 will reclose the orifice 20c, so gas emissions will be aborted. 20 [0065] Regardless of whether the reservoir is used in a gas range or in another application, in the tank body 2 When the pressure exceeds kgf/cm (which is the tension of the safety valve 60 of the butane tank to compress the spring 62) The gas pressure is such that the overpressure gas inlet i2a formed on the horizontal portion 12 of the main casing is sealed by the sealing member 17 1294021 'piece 61, as illustrated in Fig. 7, The secondary housing 5 is raised and squeezed by the compression spring 62. [0066] Thus, the overpressure gas flows through the overpressure gas inlet 12a into the secondary housing 50 and through the sealing guide 52. The hole 63a of the pressure reducing spring maintaining plate 63, the hole 64a of the gasket 64, and the overpressure gas outlet 3c of the mounting cap body 3 are discharged to the outside. [0067] Similarly, the safety valve 60 is It is acted upon to exclude a portion of the φ overpressure gas to the outside, so the gas pressure in the tank body 2 is lower than the tension of the compression spring 62 in the safety valve 60. Therefore, the compression spring 62 provides a restoring force to cause the sealing member 61 to descend to block the overpressure gas inlet 12a. When the sealing member 61 descends and blocks the overpressure gas inlet 12a, the gas discharge through the secondary casing 5 will be suspended to prevent unnecessary gas discharge. 15 The second component of the example #1〇0691 has the same component number as the corresponding component described in the first embodiment. 100701 with reference to Figures 8 to 12, another valve assembly according to another aspect of the present invention for a gas storage tank includes: one main casing 1 形成 formed separately but can be assembled, and a primary casing % ,. 100711 means that the main casing 10 has a guide member 16 extending outward from a longitudinal position along its outer surface in a vertical portion n. The horizontal portion 12 of the main casing 1G' has a guide bar 15 which is longitudinally formed along its surface. The secondary housing has a curved portion 50c forming a bottom portion of 18 1294021 to contact the outer surface of the horizontal portion 12 of the main casing. Each end of the curved portion 5〇c is formed to be detachably inserted into the guide rail 15 while the one rail positioning piece 53 is convex to prevent the secondary housing 5'' from vertically mobile. A guide slot 50d is formed in the outer surface of the secondary housing 50 to connect the guide member 16 to the secondary housing 50 in a separable manner. [0072] Therefore, 'when the main casing 10' and the secondary casing 50 are in the separated state, the secondary casing 50 is disposed such that the bar positioning piece 53 is inserted into the guide bar 15 And the secondary housing 5 is horizontally pushed toward the vertical portion 12 of the main housing 10f so that the strip positioning piece 53 can be completely inserted into the guide strip 15, and The guide member 16 of the main housing 10' is inserted into the guide slot 50d of the secondary housing 50. The main housing 1〇 will thus be joined to the secondary housing 5〇. [0073] Here, the main casing 10' and the secondary casing 50 are formed by a knife and then joined, and unlike the first embodiment, the main gas passage 10a does not The overpressure gas passage 5〇a is connected, so that the 5th secondary housing 50' includes another overpressure gas inlet 50e formed at a central bottom portion thereof to allow the overpressure gas to flow from the inside of the tank body 2 The overpressure gas passage 50a. In addition, the secondary housing 50 has an overpressure gas inlet slot 50f formed along the length of the bottom thereof, and the overpressure gas inlet 50e is formed in the overpressure gas inlet slot 5 The center of 〇f is such that overpressure gas is fed from within the tank body 2. 19 1294021 [0075] To be re-explained, the overpressure gas does not pass through the main gas passage 10a of the main casing 10', but directly enters the secondary casing 50 from the tank body 2, The overpressure gas inlet slot 50f then enters the overpressure gas inlet 50e, the overpressure gas passage 50a, the relief valve 560, and is discharged through the overpressure gas outlet 3c. [0〇76] The end of the guide member 16 has an insertion portion 16a for insertion into the guide slot 50d. Locking projections 16b and 50g are provided at opposite ends of the insertion portion 16a, and are disposed in opposite wall faces of the guiding slots 5〇d, etc., when the insertion portion 16a is inserted into the guiding slot 50d 10 The lock is secured to avoid detachment of the secondary housing 50 from the guide member 16 laterally. The operation of the valve member assembly for a gas storage tank according to the second embodiment is similar to that of the first embodiment, and thus is omitted herein. [〇〇78J According to the present invention, a valve member assembly for a gas storage tank, in addition to the 15 main casings, provides a secondary crust having a wide dry body, and one is disposed in the secondary casing. The safety valve is used to vent the overpressure gas to the outside, thus avoiding the use of larger springs. [0079] 20 simultaneously 'because the main gas path for the exhaust gas during the normal operation and the overpressure gas path for the discharge of the (four) gas are separately installed, which can avoid the use of the same path in the related art The problem associated with venting gases and overpressure gases during normal operation. _〇] Further, by forming a positioning guide from the surface of the main (four) material and horizontally extending the moving blocker, the secondary 20 1294021 is disposed near the main casing, and avoids compression by the safety valve. The resulting vertical movement of the primary and secondary housings. Not to mention 100811, when the safety valve is assembled, the compression spring maintains the plate to contact the top end of the compression spring and restricts its movement by maintaining the projection to allow the sealing member in the secondary housing to The compression spring can be easily assembled and allows the gasket to be easily installed without being affected by the compression spring.

[0082] It will be apparent to those skilled in the art that various modifications and changes can be made in the present invention. Therefore, the present invention is intended to cover such modifications and alternatives BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a valve member assembly for a gas storage tank according to the related art; FIG. 2 is a view of a gas storage tank according to a specific example of the present invention.
