Description

Technical Field

[0001] The present application is related to a gas container, and in particular to a switch valve of a gas container. Background Art

[0002] The switch valve seat of the gas container is mainly used to control whether the gas container can transmit gas. If it is opened, it can be transmitted, otherwise it cannot be transmitted if it is closed.

[0003] The existing switch valve seat is a structure of a stud with a screw hole, and the screw hole is connected to the gas hole. The stud moves up and down relative to the screw hole by rotating forward or reverse, that is, the stud blocks the gas hole to prevent gas transmission. Of course, the stud can also be moved away from the gas hole to allow gas to pass.

[0004] However, the existing stud-and-threaded hole structure of the switch valve seat is screwed together by threads. After a long period of rotation and friction, the threads will inevitably be easily worn or dirty. Or when the user applies improper force during the rotation operation, the threads may get stuck, and it will be impossible to confirm whether the switch valve seat is open or closed. If it is stuck in the fully open state, but it is mistakenly believed to be in the closed state and the gas container is replaced, it will cause a large amount of gas leakage, and may even cause dangerous situations such as fire or gas explosion.

[0005] Furthermore, the existing switch valve seat uses a stud to block the gas hole to prevent gas transmission, and there is no locking structure that can lock the stud in a closed state. As a result, it is easy for the switch valve seat to be opened in the process of moving the gas container or transporting the gas container due to the transporter accidentally touching the switch valve seat, or the switch valve seat to be shaken into an open state due to the vibration of the transport vehicle during travel, or it may fall out of the vehicle during transportation due to improper fixing and cause the switch valve seat to be bumped into an open state, or even the transport vehicle may overturn in a traffic accident and cause the switch valve seat to be bumped into an open state, resulting in gas leakage without knowledge, causing public danger.

[0006] Therefore, how to improve the above-mentioned deficiencies of the prior art is a major issue that the applicant of the present application is eager to solve. Summary of the invention

[0065] The detailed description and technical contents of the present application are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and explanation and are not intended to limit the present application.

[0066] The present application provides a switch valve for a gas container, such as Figure 1As shown, it is used to control whether the gas container (not shown) transmits gas. Figures 1 to 6 The schematic diagram of the present application before it is pressed is shown in FIG. Figures 7 to 10 Shown is a schematic diagram of the application after pressing, such as Figures 11 to 16 Shown is a schematic diagram of the present application after rotation.

[0067] like Figures 1 to 6 As shown, the switch valve of the gas container (hereinafter referred to as the switch valve) includes: a main body 1, a rotating structure 2 and a switch structure 3.

[0068] The main body 1 has a hollow tube 11, a joint 12 and a connecting pipe 13 which are connected and communicated with each other. The hollow tube 11, the joint 12 and the connecting pipe 13 are all hollow, and the hollow tube 11 has a hollow pipe 111 therein.

[0069] The switch structure 3 includes a barrel 31, which is hollow inside and has an inner barrel space 311, and a fixing member 312 is provided outside the barrel 31. The barrel 31 is inserted and fixed in the hollow pipe 111 of the hollow tube 11, and the barrel 31 is provided with a first vent hole 313 and a second vent hole 314 connected to the inner barrel space 311, and the first vent hole 313 is connected to the joint 12, and the second vent hole 314 is connected to the connecting pipe 13. The first vent hole 313 can be arranged on the circumferential surface of the barrel 31, and the second vent hole 314 can be arranged on one end surface of the barrel 31, but the present application does not limit this, and the first vent hole 313 and the second vent hole 314 can also be arranged at other parts of the barrel 31.

[0070] The present application does not limit the method of fixing the barrel 31 in the hollow tube 11, as long as it can be fixed, for example, the barrel 31 is fixed to the corresponding fixing member (not marked with element symbols) of the hollow tube 11 by its fixing member 312. In one embodiment, the fixing member 312 and the corresponding fixing member can be external threads and internal threads respectively, but it is not limited thereto.

[0071] The rotating structure 2 includes a rotating body 21 and an actuating rod assembly 23, and the actuating rod assembly 23 is connected to the rotating body 21. The actuating rod assembly 23 includes an actuating rod (not labeled with a component symbol) and a static valve 235. The actuating rod can be a single-piece structure or a multi-piece structure (for example, including a first actuating rod 231 and a second actuating rod 232). In this embodiment, a single-piece structure is used as an example for description.

[0072] The stationary valve 235 is fixedly arranged in the barrel 31 at a position corresponding to the second air vent 314, so that the stationary valve 235 is stationary and cannot rotate relative to the barrel 31, and the stationary valve 235 is provided with two through holes 2351 (the two through holes 2351 can be linearly opposite to each other), and the through holes 2351 pass through the two opposite end surfaces of the stationary valve 235, so that the through holes 2351 can be connected between the space 311 in the barrel and the second air vent 314.

[0073] The actuating rod is rotatably inserted into the barrel 31, and one end of the actuating rod is connected to the rotary valve 234. The rotary valve 234 has two notches 2341 (the two notches 2341 can be linearly opposite to each other). The rotary valve 234 and the static valve 235 can both be sheets with thickness, and the rotary valve 234 and the static valve 235 overlap each other in the thickness direction. Specifically, the notch 2341 is connected to the first vent 313 by corresponding to the circumference of the rotary valve 234, and the notch 2341 is also connected to the through hole 2351 by corresponding to one end surface of the rotary valve 234, so that the through hole 2351 can be connected between the notch 2341 and the second vent 314 after the rotary valve 234 rotates.

[0074] By this, Figures 1 to 6 As shown, when the switch valve of the present application has not rotated the rotating structure 2, the notch 2341 of the rotating valve 234 does not correspond to the first vent hole 313 and the through hole 2351, so the gas cannot be connected to the connecting pipe 13 from the joint 12 through the hollow pipe 11, that is, it is in a closed state and cannot transmit gas. Figures 11 to 16 As shown, when the user rotates the rotating body 21 by 90 degrees, the actuating rod and the rotating valve 234 will rotate relative to the barrel 31. After the rotating valve 234 rotates by 90 degrees, its notch 2341 will be connected to the first vent hole 313 and the through hole 2351, that is, it is in an open state and can transmit gas, so that the gas can enter the first vent hole 313 from the joint 12, and then flow out of the connecting pipe 13 from the second vent hole 314 through the notch 2341 and the through hole 2351. In other words, the switch valve of the present application can replace the existing switch valve seat, so it can avoid the use of the screw connection opening and screw connection closing methods of the related technology, and of course, there will be no more defects of the above-mentioned related technology, thereby ensuring that the gas will not leak or leak out in the closed state; even, by adding an open mark and a closed mark (not shown in the figure) on the rotating body 21, the user can easily and clearly know whether the switch valve of the present application is in an open or closed state.

[0075] like Figures 7 to 10 As shown, in order to improve safety, the rotating structure 2 must first perform a certain action before it can rotate. The switch structure 3 in the switch valve of the present application also includes a brake part 32, and the aforementioned actuating rod is a multi-piece structure. It should be noted that the rotating structure 2 is defined as the axial direction (not marked with component symbols) with the axis of the actuating rod (or the length direction of the actuating rod).

[0076] The braking portion 32 has an active space 321 therein, and the active space 321 has a braking position (eg, the upper part of the active space 321 ) and a releasing position (eg, the lower part of the active space 321 ) without a reference numeral.

[0077] The actuating rod includes a first actuating rod 231 and a second actuating rod 232. The first actuating rod 231 is axially telescopically inserted into the second actuating rod 232. The first actuating rod 231 has a disc 24, which is received in the active space 321 of the brake part 32; one end of the second actuating rod 232 is connected to a rotary valve 234.

[0078] The switch valve of the present application also includes an elastic element S, which is sleeved on the first actuating rod 231 and elastically supported between the rotating body 21 and the braking portion 32, so that after the rotating structure 2 is pressed to move downward, the elastic restoring force of the elastic element S can be used to push the rotating structure 2 up to its original position (the aforementioned braking position) after the pressing force is released.

[0079] By this, Figures 1 to 6 As shown, before the user presses, the disc body 24 is in the aforementioned original position (braking position), so that the disc body 24 is braked by the braking portion 32 and cannot rotate (i.e. locked), and the first actuating rod 231 fixed to the disc body 24 cannot drive the second actuating rod 232 to rotate relative to the barrel 31; Figures 7 to 10 As shown, when the user presses the rotating structure 2 axially, the disc 24 will move axially to the aforementioned release position, so that the disc 24 is freed from the braking of the braking portion 32 at the aforementioned braking position and can rotate (i.e. unlock), thereby enabling the first actuating rod 231 fixed to the disc 24 to drive the second actuating rod 232 together with the rotating valve 234 to rotate relative to the barrel 31. In other words, to open the switch valve, the unlocking switch structure 3 must be pressed first, thereby preventing the switch valve from being accidentally opened. In addition, since the switch valve of the present application has the locking function, it also has the following advantages: the switch valve will not be opened due to vibration or collision.

[0080] The present application does not limit the structure that the first actuating rod 231 can be telescopically inserted into the second actuating rod 232. In this embodiment, the following method is used as an example for explanation. Figure 1 to Figure 2 as well as Figures 7 and 8 As shown, the first actuating rod 231 has an inserting end portion 2311 along the axial direction, and at least one plane is formed around the rod of the inserting end portion 2311 (see Figure 2 , no element symbol is indicated), one end of the second actuating rod 232 has an insertion hole 2321 adapted to the insertion end 2311 along the axial direction, so that the insertion end 2311 can be retractably inserted into the insertion hole 2321. In one embodiment, the insertion end 2311 can be as follows Figure 5 The rectangular rod shown has the insertion hole 2321 as a corresponding rectangular hole; the second actuating rod 232 is a round rod, and the inner space 311 of the cylinder is a corresponding round hole.

[0081] The present application also does not limit how the brake portion 32 brakes the disc 24. In this embodiment, the following method is used as an example for explanation. Figures 5 to 10 As shown, the braking portion 32 is connected and communicated with the cylinder portion 31 , a plurality of braking ribs 323 , 324 are provided in the braking portion 32 , and one surface and the outer periphery of the disc body 24 respectively have at least one first braking body 241 and at least one second braking body 242 .

[0082] By arranging the plurality of braking ribs 323, 324 in the braking portion 32, before pressing, the first braking body 241 of the disc body 24 will Figure 5 As shown in FIG. 1 , the second brake body 242 of the disc body 24 is blocked by the brake rib 323 and cannot rotate counterclockwise. Figure 6 As shown in FIG. 1 , the first brake body 241 is stopped by the brake rib 324 and cannot rotate clockwise; after pressing, the first brake body 241 Fig. 9 As shown in FIG. 1 , the second brake body 242 is free from the stop of the brake rib 323 and can rotate counterclockwise. Fig.10 As shown in FIG. 1 , the disc 24 is blocked by the brake rib 324 and still cannot rotate clockwise, so the disc 24 can only rotate counterclockwise; in this way, when the user rotates the rotating structure 2 counterclockwise, the disc 24 Fig.13 As shown in FIG. 1 , the brake body 242 is driven to rotate 90 degrees counterclockwise and rotates until the second brake body 242 is as shown in FIG. Fig.14 Shown is subject to the blocking of other brake ribs 324 and stops rotation. In addition, because the rotating structure 2 can only rotate 90 degrees counterclockwise under the blocking of the brake rib, there is no excessive rotation to cause the switch valve to be damaged.

[0083] In other words, the first brake body 241 is stopped by at least one of the parts of the majority of brake ribs 323 in the braking position, and the second brake body 242 is stopped by at least one of the other parts of the majority of brake ribs 324 in the braking position; the first brake body 241 is away from the at least one of the parts of the majority of brake ribs 323 in the release position, and the second brake body 242 is stopped by at least another of the other parts of the majority of brake ribs 324 in the release position.

[0084] In summary, the switch valve of the gas container of the present application can achieve the expected purpose and effect, and can solve the deficiencies of the conventional technology.

[0085] The above description is only the preferred feasible embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the description and drawings of the present application are also included in the scope of the rights of the present application and are hereby stated.
