Smart valve

Abstract

The present invention discloses an intelligent valve having a valve seat within its valve body, with a valve aperture extending vertically therethrough formed therein. An iron core is mounted on a lateral portion of the valve body. The iron core comprises a stepped shaft-shaped base fixed to the valve body and a core portion fitted with a magnetically controlled sleeve. The iron core is positioned horizontally above the valve seat. The magnetically controlled sleeve is disposed on the upper end surface of the valve seat and slides left and right to open and close the valve aperture. The valve aperture is located on the side proximal to the base of the valve body. A gap is defined between the magnetically controlled sleeve and the core portion to allow for its vertical movement. Uniformly distributed magnets are affixed to the end of the magnetically controlled sleeve facing the iron core base. Because the intelligent valve of the present invention utilizes a magnetically controlled sleeve to open and close the valve aperture, the conventional one-way valve assembly for opening and closing the valve aperture is eliminated, simplifying the structure of the intelligent valve and effectively reducing production costs.

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 valves feature intelligent identification and filling capabilities. Using an electronic identification system, a smart filling gun controls the smart valve, ensuring 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 valve is equipped with an electromagnetic drive unit and a check valve controlled by the electromagnetic drive unit. The smart valve is equipped with an electronic identifier that can be recognized by the electronic identification system to verify the legality of the gas cylinder filling. The electromagnetic drive unit is typically installed in the lateral valve body of the smart valve. It primarily consists of an iron core, which acts as a magnetic medium, and a magnetically controlled sleeve that fits within the iron core. The magnetically controlled sleeve is driven by electromagnetic force to slide toward and prevent the check valve core from moving. For example, Patent No. 201610982580.8 discloses a gas cylinder valve, equivalent to the smart valve of this application. The valve body houses a check valve consisting of a valve core and a first spring. The lateral portion of the valve body houses an electromagnetic drive unit consisting of a slide seat, a slider, and a second spring. This type of smart valve is relatively complex, with numerous components and a relatively high cost. Therefore, it is necessary to develop an intelligent valve with a simpler structure and lower cost. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent valve with a simple structure.

[0004] The technical solution adopted to solve the above technical problems is: an intelligent valve, wherein the valve body of the intelligent valve is provided with a valve seat, and a valve hole running through the valve seat is formed in the valve seat. An iron core is installed on the lateral part of the valve body, and the iron core has a base in the shape of a stepped shaft fixed to the valve body and a core with a magnetic control sleeve. The characteristic is that: the iron core is placed horizontally above the valve seat, and the magnetic control sleeve is arranged on the upper end surface of the valve seat and slides left and right to open and close the valve hole, and the valve hole is opened on the side close to the base of the valve body. There is a gap between the magnetic control sleeve and the core to allow the magnetic control sleeve to move up and down, and evenly distributed magnets are fixed to the end of the magnetic control sleeve facing the base of the iron core.

[0005] The beneficial effects brought about by the adoption of the present invention are as follows: since the intelligent valve of the present invention adopts a magnetically controlled sliding sleeve to open and close the valve hole, the current one-way valve assembly for opening and closing the valve hole is eliminated, making the structure of the intelligent valve simpler and effectively reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 Schematic diagram of the structure of the intelligent valve of the present invention. DETAILED DESCRIPTION

[0007] like Figure 1As shown, a smart valve comprises a valve body 1 having a valve seat 2 formed therein, with a valve aperture 2.1 extending vertically therethrough. An iron core 3 is mounted on the side of the valve body 1. The iron core 3 comprises a stepped, shaft-shaped base 3.1 fixed to the valve body 1, and a core 3.2 fitted with a magnetic control sleeve 4. In the present invention, the iron core 3 is positioned horizontally above the valve seat 2. The magnetic control sleeve 4 is mounted on the upper end surface of the valve seat 2 and slides left and right to open and close the valve aperture 2.1. The valve aperture 2.1 is located on the side proximal to the valve body base 3.1. A gap is defined between the magnetic control sleeve 4 and the core 3.2 to allow for its vertical movement. Uniformly distributed magnets 5 are affixed to the end of the magnetic control sleeve 4 facing the iron core base 3.1.

[0008] Under normal circumstances, the magnetic force of magnet 5 causes the magnetic sleeve 4 to be attracted to this end of the core base 3.1, blocking the valve hole 2.1. Because there is a gap between the magnetic sleeve 4 and the core 3.2, when the gas is used, the air pressure inside the cylinder pushes up the magnetic sleeve 4, opening the valve hole 2.1. However, during illegal filling, the external filling pressure pushes down on the magnetic sleeve 4, pressing it against the valve hole 2.1, closing it and preventing further filling. It is conceivable that although the magnetic sleeve 4 is attracted to the end face of the core base 3.1 due to the magnetic force of magnet 5, as long as the friction between the two contacting end faces is sufficiently low, even relatively low air pressure inside the cylinder can lift and move the magnetic sleeve 4, and higher filling pressure is sufficient to push it down. The evenly distributed magnets 5 ensure that the magnetic sleeve 4 is subjected to uniform force when moving left and right. It is understood that the uniform distribution here can be the uniform placement of two or more magnets, or a single magnetic ring. During legitimate filling, the larger electromagnetic force generated by the smart inflation gun overcomes the magnetic force of the magnet 5, driving the magnetically controlled sleeve 4 to slide away from the core base 3.1 and the valve hole 2.1, opening the valve hole 2.1 and allowing the filling gas to enter the cylinder smoothly.
