Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a manual and automatic integrated bottle head valve. Background Art

[0002] The bottle head valve is installed on the gas cylinder, and uses a needle to pierce the copper film of the gas cylinder to release the gas in the gas cylinder. The existing bottle head valves on the market are spring-activated. Before use, use a resetter to push the needle to the highest position. At this time, the spring is squeezed to the shortest position. Then use a nylon fixing pin with a pull ring to plug the tail of the needle. Remove the resetter. Under the obstruction of the nylon fixing pin, the needle will not fall. When in use, screw the reset bottle head valve onto the gas cylinder, pull out the nylon fixing pin with force, and the spring will reset. The needle will pierce the copper film of the gas cylinder under the action of the spring, and the gas in the bottle will inflate the target object through the pipeline on the bottle head valve.

[0003] The existing bottle head valve can only be started by hand pulling at a close distance and cannot be operated remotely. The existing bottle head valve fixing pin is made of nylon, which is easy to wear out after long-term use and is unreliable. Summary of the invention

[0004] The purpose of the utility model is to provide a manual and automatic integrated bottle head valve to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical measures: a manual-automatic integrated bottle head valve, which includes a hollow columnar upper cover, the upper cover is threadedly connected with a hollow valve body, the valve body is provided with an upper threaded hole and a lower threaded hole, the upper threaded hole is connected with an air inlet adapter, and the lower threaded hole is connected with an air outlet adapter; a piston push rod is arranged in the upper cover, a protruding piston part is arranged in the middle of the piston push rod, a second sealing ring is arranged on the piston part, and a pin hole is arranged on the piston push rod, and the pin hole is used to pass a stainless steel pin; an upper cavity and a lower cavity are arranged on the valve body, the upper cavity is communicated with the upper threaded hole, the lower cavity is communicated with the lower threaded hole, a piston piercing needle is penetrated between the upper cavity and the lower cavity, a third sealing ring is arranged at the end of the piston piercing needle, a return spring is arranged in the upper cavity, the return spring is arranged on the piston piercing needle, and a fourth sealing ring for sealing with the gas cylinder is arranged in the lower cavity.

[0006] Compared with the prior art, the utility model has the advantages that the gas passes through the air inlet adapter, pushes the piston needle downward, pierces the copper film seal of the gas cylinder, and allows the gas in the gas cylinder to pass through the air outlet adapter to inflate the target object, thereby realizing remote control. In addition, the stainless steel latch can be used for a long time without wear and tear.

[0007] As an improvement of the present invention, the internal shape of the upper cavity is a stepped two-layer structure. The purpose of this design is that when the piston needle moves downward, the return spring is compressed. The restoring force of the return spring is much smaller than the air pressure, so it will not affect the piston needle from piercing the copper film seal of the gas cylinder. After the piston needle pierces the copper film seal of the gas cylinder, the step on the piston needle contacts the step of the upper cavity, and the return spring is in a compressed rather than over-compressed state, thereby extending the service life of the return spring. This stepped two-layer structure can protect the return spring.

[0008] As an improvement of the utility model, the upper cover and the valve body are both provided with a step surface. The purpose of selecting this design is that when the upper cover and the valve body are disassembled, the disassembly tool can clamp the step surface for operation without leaving scratches on the surface.

[0009] As an improvement of the utility model, a sealing gasket is placed in front of the air inlet adapter and the air outlet adapter. The purpose of selecting this design is to further improve the sealing between the adapter and the valve body.

[0010] As an improvement of the utility model, the upper cover is provided with an internal thread, the valve body is provided with an external thread, and a sealing groove for placing a first sealing ring is provided at the bottom of the external thread. The purpose of selecting this design is to further improve the sealing between the upper cover and the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] Example 1

[0020] Please refer to Figure 1 -4. The present embodiment provides a manual-automatic integrated bottle head valve, comprising a hollow cylindrical upper cover 1, wherein the upper cover 1 is threadedly connected to a hollow valve body 2, wherein the valve body 2 is provided with an upper threaded hole 3 and a lower threaded hole 4, wherein the upper threaded hole 3 is connected to an air inlet adapter 5, and wherein the lower threaded hole 4 is connected to an air outlet adapter 6; wherein a piston push rod 7 is arranged inside the upper cover 1, wherein a protruding piston portion is arranged in the middle of the piston push rod 7, wherein a second sealing ring 8 is arranged on the piston portion, wherein a pin hole 9 is arranged on the piston push rod 7, wherein the pin hole 9 is used to pass a stainless steel plug 10.

[0021] The valve body 2 is provided with an upper cavity 11 and a lower cavity 12, the upper cavity 11 is communicated with the upper threaded hole 3, the lower cavity 12 is communicated with the lower threaded hole 4, a piston needle 13 is passed through the upper cavity 11 and the lower cavity 12, a third sealing ring 14 is provided at the end of the piston needle 13, a return spring 15 is provided in the upper cavity 11, the return spring 15 is provided on the piston needle 13, and a fourth sealing ring 17 for sealing with the gas cylinder 16 is provided in the lower cavity 12.

[0022] Furthermore, the internal shape of the upper cavity 11 is a stepped two-layer structure. With this new structure, when the piston needle 13 moves downward, the return spring 15 is compressed accordingly, and the restoring force of the return spring 15 is much smaller than the air pressure, so it will not affect the piston needle 13 from piercing the copper film seal 23 of the gas cylinder. After the piston needle 13 pierces the copper film seal 23 of the gas cylinder, the step on the piston needle 13 contacts the step of the upper cavity 11, and the return spring 15 is in a compressed rather than over-compressed state, thereby extending the service life of the return spring 15.

[0023] Furthermore, both the upper cover 1 and the valve body 2 are provided with a step surface 20. When the upper cover 1 and the valve body 2 are disassembled, the disassembly tool can clamp the step surface 20 for operation without leaving scratches on the surface.

[0024] Furthermore, sealing gaskets 18 are placed in front of the air inlet adapter 5 and the air outlet adapter 6 to improve the sealing between the adapter and the valve body 2 .

[0025] Furthermore, the upper cover 1 is provided with an internal thread, the valve body 2 is provided with an external thread, and a sealing groove for placing a first sealing ring 19 is provided at the bottom of the external thread to improve the sealing between the upper cover 1 and the valve body 2.

[0026] Furthermore, a groove 26 is provided at the front end of the piston needle 13 , and gas rushes out from the groove 26 during operation.

[0027] In the embodiments of the present utility model application, please refer to Figure 1 and Figure 2 The working principle of the manual and automatic integrated bottle head valve is as follows:

[0028] Automatic start: The gas generated by the gas controller 24 enters the valve body 2 through the air pipe and the air inlet adapter 5 on the manual-automatic integrated valve. Under the action of the sealing ring, etc., the cavity is a closed chamber. The piston needle 13 moves downward under the push of the gas, piercing the copper film seal 23 of the gas cylinder in the gas cylinder head 22. The gas in the gas cylinder 16 rushes out from the gas outlet adapter 6 at the lower end through the groove of the piston needle 13, and enters the inflation unit (inflating the target object) through the pipeline. After use, the gas controller 24 is deflated, and the piston needle 13 returns to its original position under the action of the reset spring 15.

[0029] Manual start: Pull the stainless steel plug 10 open with force, and the piston push rod 7 pushes the piston needle 13 downward under the elastic force of the compression spring 21, piercing the copper film seal 23 of the gas cylinder in the gas cylinder head 22. The gas in the gas cylinder 16 rushes out from the gas outlet adapter 6 at the lower end through the groove of the piston needle 13, and enters the gas expansion unit through the pipeline. After use, the upper cover 1 needs to be removed, and the compression spring 21 and the piston push rod 7 need to be compressed to the original position with a resetter, and the stainless steel plug 10 needs to be inserted to fix it, and the upper cover 1 and the valve body 2 are tightened to complete the manual-automatic integrated valve reset.

[0030] In the prior art, since the existing bottle head valves cannot be linked to multiple ones, although the pull rings of multiple bottle head valves can be tied together for use, the reliability and opening synchronization cannot be guaranteed. Figure 3 The gas controller 24 is connected to the air inlet adapters 5 of three sets of manual-automatic integrated bottle head valves through three air inlet pipes 25 to achieve multiple linkages and ensure the synchronization of opening.

[0031] The utility model has the beneficial effects that the gas passes through the gas inlet adapter 5, pushes the piston needle 13 downward, pierces the copper film seal 23 of the gas cylinder, and allows the gas in the gas cylinder 16 to pass through the gas outlet adapter 6 to inflate the target object, thereby realizing remote control. In addition, the stainless steel bolt 10 can be used for a long time without wear.
