Description

Switch valve for gas container

Technical Field

The present application relates to gas containers, and more particularly to a gas container on-off valve.

Background

The valve seat of the gas container is mainly used for controlling whether the gas container can transmit gas, and when the valve seat is opened, the gas container can transmit gas, and when the valve seat is closed, the valve seat can not transmit gas.

The existing switch valve seat is of a structure that a screw bolt is matched with a screw hole, and the screw hole is communicated with a gas hole. The stud is rotated forwards or backwards to move up and down relative to the screw hole, namely, the stud is used for blocking the gas hole to prevent gas transmission, and the stud is used for keeping away from the gas hole to allow gas to pass through.

However, the structure of the stud matching screw hole of the existing switch valve seat is that the threads are in threaded connection with each other, when the threads rotate back and forth and rub after a long time, the threads are easy to wear or dirty, or when a user rotates and operates, the threads are blocked because of improper force application, the switch valve seat cannot be confirmed to be opened or closed, if the switch valve seat is blocked in a fully opened state, the switch valve seat is mistakenly considered to be closed, and the gas container is replaced, so that a large amount of gas can leak, and even dangerous situations such as fire or gas explosion can occur.

Moreover, the existing switch valve seat uses the stud to block the gas hole to prevent gas transmission, and has no locking structure capable of locking the stud in a closed state, so that the switch valve seat is easily opened in an open state due to mistaken touching of the switch valve seat by a carrier in the process of carrying the gas container or in the process of transporting the gas container, or the switch valve seat is vibrated to be opened in the open state due to vibration of a transport vehicle in the process of travelling, or the switch valve seat falls out of the vehicle and is prevented from being collided to be opened due to improper fixation Guan Fa in the process of transporting, or even the transport vehicle is overturned due to a car accident and is prevented from being collided to be opened due to collision Guan Fa, and gas leakage occurs under the condition of unknowing, so that public danger is caused.

Therefore, how to solve the above-mentioned drawbacks of the prior art is a major problem to be solved by the applicant of the present application.

Detailed Description

The detailed description and technical content related to the present application are described below in conjunction with the drawings, which are however provided for reference and illustration only and are not intended to limit the present application.

The present application provides a switch valve of a gas container, as shown in fig. 1, for controlling whether the gas container (not shown in the figure) transmits gas. Fig. 1 to 6 are schematic diagrams before the present application is not pressed, fig. 7 to 10 are schematic diagrams after the present application is pressed, and fig. 11 to 16 are schematic diagrams after the present application is rotated.

As shown in fig. 1 to 6, the on-off valve (hereinafter referred to as on-off valve) of the gas container includes: a main body 1, a rotating structure 2 and a switch structure 3.

The body 1 has a hollow pipe 11, a joint 12 and a connection pipe 13 connected and communicating with each other. The hollow pipe 11, the joint 12 and the connection pipe 13 are all hollow, and the hollow pipe 11 is internally provided with a hollow pipeline 111.

The switch structure 3 includes a cylindrical portion 31, a hollow cylindrical portion 31 having an inner space 311, and a fixing member 312 outside the cylindrical portion 31. The tube 31 is inserted and fixed in the hollow pipe 111 of the hollow pipe 11, the tube 31 is provided with a first vent hole 313 and a second vent hole 314 which are communicated with the space 311 in the tube, the first vent hole 313 is communicated with the joint 12, and the second vent hole 314 is communicated with the connecting pipe 13. The first vent hole 313 may be disposed on the circumferential surface of the cylindrical portion 31, and the second vent hole 314 may be disposed on one end surface of the cylindrical portion 31, but the present application is not limited thereto, and the first vent hole 313 and the second vent hole 314 may be disposed on other portions of the cylindrical portion 31.

The present application does not limit the manner in which the cylindrical portion 31 is fixed in the hollow tube 11, as long as it can be fixed, and for example, the cylindrical portion 31 is fixed to a corresponding fixing member (not shown) of the hollow tube 11 by the fixing member 312. In one embodiment, the fastening member 312 and the corresponding fastening member may be external threads and internal threads, respectively, but not limited thereto.

The rotary structure 2 includes a rotary body 21 and an actuator rod assembly 23, the actuator rod assembly 23 being connected to the rotary body 21. The actuator rod assembly 23 includes an actuator rod (not shown) and a rest valve 235, which may be of a one-piece construction or of a multi-piece construction (e.g., including a first actuator rod 231 and a second actuator rod 232), as illustrated in this embodiment.

The standing valve 235 is fixedly disposed in the cylinder 31 corresponding to the second vent 314, such that the standing valve 235 is stationary and cannot rotate relative to the cylinder 31, and the standing valve 235 is provided with two through holes 2351 (the two through holes 2351 may be linearly opposite to each other), and the through holes 2351 penetrate through two opposite end surfaces of the standing valve 235, such that the through holes 2351 may be communicated between the cylinder space 311 and the second vent 314.

The actuating rod is rotatably inserted into the barrel 31, one end of the actuating rod is connected with a rotary valve 234, and the rotary valve 234 is provided with two notches 2341 (the two notches 2341 can be linearly opposite to each other). The rotary valve 234 and the stationary valve 235 may each be a sheet having a thickness, and the rotary valve 234 and the stationary valve 235 are overlapped with each other in the thickness direction. Specifically, the notch 2341 communicates with the first vent hole 313 corresponding to the peripheral surface of the rotary valve 234, and the notch 2341 also communicates with the through hole 2351 corresponding to one end surface of the rotary valve 234, so that the through hole 2351 can communicate between the notch 2341 and the second vent hole 314 after the rotary valve 234 rotates.

Accordingly, as shown in fig. 1 to 6, when the switching valve of the present application does not rotate the rotating structure 2, the notch 2341 of the rotating valve 234 does not correspondingly communicate with the first vent hole 313 and the through hole 2351, so that the gas cannot be communicated with the connecting tube 13 from the joint 12 through the hollow tube 11, that is, the gas cannot be transmitted in a closed state. As shown in fig. 11 to 16, when the user rotates the rotator 21 by 90 degrees, the actuating rod is driven to rotate together with the rotary valve 234 relative to the cylinder 31, and the rotary valve 234 rotates by 90 degrees to enable the notch 2341 to be correspondingly communicated between the first vent hole 313 and the through hole 2351, that is, to be in an open state so as to transmit gas, so that the gas can enter the first vent hole 313 from the connector 12, and then flow out of the connecting tube 13 from the second vent hole 314 through the notch 2341 and the through hole 2351. In other words, the switch valve can replace the existing switch valve seat, so that the screw-on and screw-off modes of the related technology can be avoided, and all the defects of the related technology can be avoided, thereby ensuring that the gas in the closed state can not leak; even, the opening and closing marks (not shown) can be added on the rotating body 21 to enable the user to easily and clearly know whether the switching valve is in the open or closed state.

As shown in fig. 7 to 10, in order to improve safety, the rotating structure 2 must perform a certain action before rotating, and the switch structure 3 in the switch valve of the present application further includes a braking portion 32, and the actuating rod is of a multi-piece structure. The axis of the rotation structure 2 (or the length direction of the actuation rod) is defined as an axial direction (not labeled with a reference numeral).

The braking portion 32 has a movable space 321 therein, and the movable space 321 has a braking position (e.g., an upper portion of the movable space 321) and a releasing position (e.g., a lower portion of the movable space 321) in which no reference symbol is given.

The actuating rod includes a first actuating rod 231 and a second actuating rod 232, and the first actuating rod 231 is axially telescopically inserted into the second actuating rod 232. The first actuating lever 231 has a disk 24, and the disk 24 is accommodated in the movable space 321 of the brake 32; a rotary valve 234 is connected to one end of the second actuating lever 232.

The switch valve further comprises an elastic element S, wherein the elastic element S is sleeved on the first actuating rod 231 and is elastically supported between the rotating body 21 and the braking portion 32, so that after the rotating structure 2 is pressed down, the rotating structure 2 can be pushed to move up to the original position (the braking position) by utilizing the elastic restoring force of the elastic element S after releasing the pressing force channel.

Accordingly, as shown in fig. 1 to 6, when the user does not press, the disc 24 is located at the original position (braking position), such that the disc 24 is braked by the braking portion 32 and cannot rotate (i.e. locked), and such that the first actuating rod 231 fixed to the disc 24 cannot drive the second actuating rod 232 to rotate together with the cylinder 31; as shown in fig. 7 to 10, when the user presses the rotating structure 2 in the axial direction, the disc 24 moves to the release position in the axial direction, so that the disc 24 is released from the braking of the braking portion 32 at the braking position and can rotate (i.e. unlock), and the first actuating rod 231 fixed to the disc 24 can drive the second actuating rod 232 to rotate together with the rotary valve 234 relative to the barrel 31. In other words, to open the on-off valve, the unlocking switch structure 3 must be pressed first, so that the on-off valve can be prevented from being opened by erroneous touch. In addition, the switching valve of the present application has the above locking function, and therefore further has: the condition that the switch valve is opened due to vibration or collision is avoided.

The present utility model is not limited to the structure in which the first actuating lever 231 is telescopically inserted into the second actuating lever 232, and in this embodiment, a description will be given by way of example. As shown in fig. 1 to 2 and fig. 7 to 8, the first actuating rod 231 has an insertion end 2311 along an axial direction, at least one plane (not labeled with a reference symbol in fig. 2) is formed around the rod of the insertion end 2311, and one end of the second actuating rod 232 has an insertion hole 2321 adapted to the insertion end 2311 along an axial direction, so that the insertion end 2311 is telescopically inserted into the insertion hole 2321. In an embodiment, the plugging end 2311 may be a rectangular rod as shown in fig. 5, and the plugging hole 2321 is a rectangular hole corresponding thereto; the second actuating rod 232 is a round rod, and the space 311 in the cylinder is a round hole corresponding to the round rod.

The present application also does not limit how the brake unit 32 brakes the disk 24, and in this embodiment, a description will be given by way of example. As shown in fig. 5 to 10, the braking portion 32 and the cylindrical portion 31 are connected to each other and communicate, a plurality of braking ribs 323, 324 are provided in the braking portion 32, and at least one first braking body 241 and at least one second braking body 242 are provided on one surface and the outer periphery of the disc 24, respectively.

By disposing the plurality of braking ribs 323, 324 in the braking portion 32, before pressing, the first braking body 241 of the disc 24 is stopped by the braking rib 323 and cannot rotate counterclockwise as shown in fig. 5, and the second braking body 242 of the disc 24 is stopped by the braking rib 324 and cannot rotate clockwise as shown in fig. 6; after pressing, the first braking body 241 is released from the stop of the braking rib 323 and can rotate counterclockwise as shown in fig. 9, and the second braking body 242 is still stopped by the braking rib 324 and cannot rotate clockwise as shown in fig. 10, so that the disc 24 can only rotate counterclockwise; in this way, when the user rotates the rotating structure 2 counterclockwise, the disc 24 is rotated 90 degrees counterclockwise as shown in fig. 13, and the second brake 242 is stopped by the other brake ribs 324 as shown in fig. 14. Further, since the rotary structure 2 can be rotated only 90 degrees counterclockwise by the stopper of the stopper rib, there is no case where the switching valve is damaged due to excessive rotation.

In other words, first brake body 241 is stopped by at least one of a portion of plurality of brake ribs 323 in the braking position, and second brake body 242 is stopped by at least one of another portion of plurality of brake ribs 324 in the braking position; the first braking body 241 is away from the at least one of the portions of the plurality of braking ribs 323 in the released position and the second braking body 242 is blocked by at least one other of the other portions of the plurality of braking ribs 324 in the released position.

In summary, the on-off valve of the gas container can achieve the expected purpose and effect, and can solve the disadvantages of the prior art.

The foregoing description is only illustrative of the preferred embodiments of the present application and is not intended to limit the scope of the claims, which follow, in view of the structural equivalents employed in the description and drawings of the present application.
