Description

Technical Field

[0001] The present invention relates to the technical field of bottle valves, in particular to a bottle valve with intelligent filling recognition function. Background Art

[0002] Smart bottle valves feature intelligent identification and filling capabilities. Using an electronic identification system, the smart filling gun controls the smart valve to ensure legal filling of gas cylinders. Typically, the smart filling gun is equipped with an electromagnetic control device controlled by the electronic identification system, while the smart bottle valve is equipped with an electromagnetic drive unit and a one-way valve controlled by the electromagnetic drive unit. The smart bottle valve is equipped with an electronic identifier that can be recognized by the electronic identification system to confirm the legality of the gas cylinder filling. Typically, the electromagnetic drive unit is installed within the lateral valve body of the smart bottle valve. It primarily consists of an iron core that acts as a magnetic medium, a magnetically controlled sleeve that fits within the iron core, and a spring that prevents the magnetic sleeve from sliding away from the one-way valve. The magnetically controlled sleeve is driven by magnetic force to slide toward and prevent the one-way valve core from moving. The one-way valve core is typically located within the valve body and slides back and forth against the valve hole to open and close the valve hole. Patent No. 201610982580.8 discloses a gas cylinder valve, equivalent to the smart bottle valve of this application. The valve stem 4 (equivalent to the one-way valve core) comprises a spherical portion 41 (equivalent to the valve portion) on its lower half, which abuts against the valve orifice and closes it, and a guide tab 43 (equivalent to the sliding portion) that slides with the valve body. The upper half is designed to engage with a slider 6 (equivalent to the magnetic sleeve). Because the sliding portion is located in the lower half of the one-way valve core, while the upper half engages with the magnetic sleeve, the magnetic sleeve strikes the upper half upon actuation. This impact generates a torque on the lower half of the sliding portion. Clearly, this torque is detrimental to the sliding component, easily causing wear or deformation, leading to unsmooth, insensitive, or even damage. Therefore, the design of the one-way valve core of this smart bottle valve is problematic and warrants improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent bottle valve with more superior design performance.

[0004] The technical solution adopted to solve the above technical problems is: an intelligent bottle valve, in which a one-way valve core for blocking the inflation of gas into the cylinder is installed in the valve body of the intelligent bottle valve, the valve body has a lateral valve body, and an electromagnetic drive unit is installed in the lateral valve body, which is controlled by the electromagnetic control device of the intelligent inflation gun to prevent the one-way valve core from moving. The electromagnetic drive unit includes an iron core fixed to the lateral valve body, a magnetic control sleeve sleeved on the iron core, and a first spring that maintains the tendency of the magnetic control sleeve to slide away from the one-way valve core, and is characterized in that: the one-way valve core includes a valve part in the lower half and a sliding part in the upper half that slides with the wall of the valve body, the sliding part forms a circumferentially extending retaining groove for accommodating the insertion of the magnetic control sleeve and an axially extending slide groove whose depth is deeper than the retaining groove, and the iron core extends into the slide groove and slides with the slide groove.

[0005] On the basis of the above, a dynamic valve seat is provided between the one-way valve core and the valve hole of the valve body, which slides in the inner wall of the valve body. The dynamic valve seat forms a central through hole. The upper port of the central through hole is abutted and sealed with the valve part of the one-way valve core, and the outer peripheral wall of the lower port is abutted and sealed with the edge of the valve hole. A second spring is installed between the dynamic valve seat and the fixed valve seat forming the valve hole to keep the dynamic valve seat from sliding away from the fixed valve seat.

[0006] On the basis of the above, a retaining spring and a sealing ring for securing the iron core are installed between the iron core and the lateral valve body.

[0007] The present invention offers the following beneficial effects: Because the upper portion of the one-way valve core, which engages with the magnetically controlled sliding sleeve, is designed as a sliding portion that slidably engages with the valve body, the sliding portion and the one-way valve core are integrated into the same part. This protects the entire one-way valve core from torque generated by external forces. Consequently, the present invention offers a more rational design, superior performance, more reliable operation, and a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a structural schematic diagram of the electromagnetic drive unit and the one-way valve core in the present invention. DETAILED DESCRIPTION

[0010] like Figure 1 、 2 As shown, a smart bottle valve has a valve body 1 equipped with a one-way valve core 2 for blocking inflation into a cylinder. The valve body 1 includes a lateral valve body 1.1. An electromagnetic drive unit, controlled by the electromagnetic control device of a smart inflation gun, is installed within the lateral valve body 1.1 to prevent the one-way valve core 2 from moving. The electromagnetic drive unit comprises an iron core 3 fixed to the lateral valve body 1.1, a magnetically controlled sliding sleeve 4 encased in the iron core 3, and a first spring 5 that prevents the magnetically controlled sliding sleeve 4 from sliding away from the one-way valve core 2. In the present invention, the one-way valve core 2 comprises a valve portion 2.1 in the lower half and a sliding portion 2.2 in the upper half that slidably engages with the inner wall of the valve body 1. The sliding portion 2.2 defines a circumferentially extending retaining groove 2.3 for receiving the magnetically controlled sliding sleeve 4, and an axially extending slide groove 2.4 that is deeper than the retaining groove 2.3. The iron core 3 extends into and slidably engages with the slide groove 2.4.

[0011] The magnetic control sliding sleeve 4 is in the form of a sleeve on the iron core 3. The iron core 3 extends to the bottom of the sliding groove 2.4, and the extended end forms a smooth end surface to slide with the groove bottom of the sliding groove 2.4, and the two sides of the extended end of the iron core 3 also slide with the groove walls on both sides of the sliding groove 2.4, combined with the sliding cooperation of the outermost circumferential wall of the sliding part 2.2 and the inner wall of the valve body 1, which plays a superior sliding guide role for the one-way valve core 2. The impact of the magnetic control sliding sleeve 4 on the one-way valve core 2 is a positive force, and no torque is generated, which completely eliminates the influence of torque on the one-way valve core, making the action of the one-way valve core 2 more sensitive and reliable, and prolonging the service life.

[0012] In this embodiment, the one-way valve core 2 and the valve hole 1.2 of the valve body 1 are provided with a movable valve seat 6 that slides with the inner wall of the valve body 1. The movable valve seat 6 forms a central through hole 6.1, the upper port of the central through hole 6.1 abuts and seals with the valve part 2.1 of the one-way valve core 2, and the outer circumferential wall of the lower port abuts and seals with the port of the valve hole 1.2. The second spring 8 is installed between the movable valve seat 6 and the fixed valve seat 7 that forms the valve hole 1.2 to keep the movable valve seat 6 from sliding away from the fixed valve seat 7. Under normal circumstances, the movable valve seat 6 and the fixed valve seat 7 are kept separate, and the liquefied gas in the cylinder will rush open the one-way valve core 2 to supply gas. When legally filling liquefied gas, the electromagnetic control device of the intelligent filling gun is started to generate a magnetic force to drive the magnetic control sliding sleeve 4 to slide towards the one-way valve core 2 and insert into the blocking groove 2.3 to block the movement of the one-way valve core 2. The filled liquefied gas will separate the movable valve seat 6 and the valve part 2.1, and the liquefied gas will enter the cylinder through the central through hole 6.1 and the valve hole 1.2. When illegally filling, the electromagnetic control device is not triggered to start, the magnetic control sliding sleeve 4 does not act, and the liquefied gas will press the one-way valve core 2 and the movable valve seat 6, closing the central through hole 6.1 and the valve hole 1.2, and blocking the filling, achieving illegal limited filling.

[0013] Obviously, the drawings only provide a structural schematic diagram of the embodiment of the intelligent cylinder valve, and the embodiment adds the movable valve seat 6, which is to improve the sensitivity and reliability of the one-way valve action by another method. When the movable valve seat 6 is removed, the one-way valve core 2 can also achieve the purpose of the invention of the intelligent cylinder valve, and this design is a conventional design.

[0014] Further, the iron core 2 and the lateral valve body 1.1 are provided with a clamping spring 9 and a sealing ring 10 for clamping and fixing the iron core 2. Since the iron core 2 is installed and fixed by the clamping spring 9, the clamping spring 9 is completely hidden in the valve body, and illegal personnel cannot disassemble the electromagnetic drive unit intact, unless it is violently and destructively disassembled, which plays a good role in preventing illegal disassembly.
