Description

Intelligent cylinder valve

Technical Field

The utility model relates to a cylinder valve technical field specifically indicates to have intelligent recognition and fill the cylinder valve that fills dress.

Background

The intelligent cylinder valve has an intelligent recognition filling function, and the intelligent cylinder valve is controlled by the intelligent inflating gun by utilizing an electronic recognition system, so that legal filling of the gas cylinder is realized. An electromagnetic control device controlled by an electronic identification system is usually installed on the intelligent inflation gun, and an electromagnetic driving unit controlled by the electromagnetic control device and a one-way valve controlled by the electromagnetic driving unit are installed on the intelligent cylinder valve. And the intelligent cylinder valve is provided with an electronic identifier which can be identified by an electronic identification system so as to confirm the legality of filling the gas cylinder. Generally, an electromagnetic driving unit is arranged in a lateral valve body of the intelligent cylinder valve and mainly comprises an iron core serving as a magnetic force medium, a magnetic control sliding sleeve sleeved on the iron core and a spring keeping the trend that the magnetic control sliding sleeve slides away from the one-way valve, and the magnetic control sliding sleeve can be driven by magnetic force to slide towards and prevent the one-way valve core from moving. The one-way valve core is usually arranged in the valve body and slides in a reciprocating manner opposite to the valve hole, so that the valve hole is opened and closed. The patent No. 201610982580.8 discloses a gas cylinder valve, which is equivalent to the smart cylinder valve of the present application, wherein the valve rod 4 (equivalent to a one-way valve core) has a lower half portion forming a spherical portion 41 (equivalent to a valve portion) capable of abutting against a closed valve hole and a guiding protruding piece 43 (equivalent to a sliding portion) in sliding fit with the valve body, and an upper half portion for inserting and blocking fit with a sliding block 6 (equivalent to a magnetic control sliding sleeve). Because the sliding part is arranged at the lower half part of the one-way valve core, and the upper half part is matched with the magnetic control sliding sleeve in a blocking way, the magnetic control sliding sleeve can impact the upper half part after acting, and the lower half part as the sliding part can be subjected to moment generated by impact. Obviously, such a moment is disadvantageous for sliding parts and can easily cause wear of sliding parts or deformation of parts, resulting in unsmooth, insensitive or even damaged movement of parts. Therefore, the design of the one-way valve cartridge of the smart cylinder valve is problematic and needs to be improved.

Detailed Description

As shown in figures 1 and 2, a one-way valve core 2 used for plugging and inflating a steel cylinder is installed in a valve body 1 of the intelligent cylinder valve, the valve body 1 is provided with a lateral valve body 1.1, an electromagnetic driving unit controlled by an electromagnetic control device of an intelligent inflation gun to prevent the one-way valve core 2 from acting is installed in the lateral valve body 1.1, and the electromagnetic driving unit comprises an iron core 3 fixed with the lateral valve body 1.1, a magnetic control sliding sleeve 4 sleeved on the iron core 3 and a first spring 5 keeping the trend that the magnetic control sliding sleeve 4 slides away from the one-way valve core 2. The utility model discloses in, check valve core 2 includes in the valve portion 2.1 of the latter half and in the first half with 1 inner wall sliding fit's of valve body sliding part 2.2, sliding part 2.2 forms that circumference extension holding magnetic control sliding sleeve 4 inserts the fender groove 2.3 that keeps off and axial extension groove depth ratio keeps off the spout 2.4 that groove 2.3 is dark, iron core 3 extends to in the spout 2.4 with spout 2.4 sliding fit.

The magnetic control sliding sleeve 4 is sleeved on the iron core 3 in a lantern ring mode. The iron core 3 extends to the groove bottom close to the sliding groove 2.4, the extending end of the iron core can form a smooth end face to be in sliding fit with the groove bottom of the sliding groove 2.4, meanwhile, two sides of the extending end of the iron core 3 are also in sliding fit with groove walls on two sides of the sliding groove 2.4, and the peripheral wall of the outermost edge of the sliding part 2.2 is combined with the sliding fit with the inner wall of the valve body 1, so that the one-way valve core 2 is excellently guided in a sliding mode. When the magnetic control sliding sleeve 4 acts, the impact on the one-way valve core 2 is a positive acting force, so that moment can not be generated, the influence of the moment on the one-way valve core is thoroughly eliminated, the action of the one-way valve core 2 is more sensitive and reliable, and the service life is long.

In this embodiment, a movable valve seat 6 which is in sliding fit with the inner wall of the valve body 1 is arranged between the check valve element 2 and the valve hole 1.2 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 is in butt seal with the valve portion 2.1 of the check valve element 2, the outer peripheral wall of the lower port is in butt seal with the port edge of the valve hole 1.2, and a second spring 8 which keeps the movable valve seat 6 to slide away from the fixed valve seat 7 is arranged between the movable valve seat 6 and the fixed valve seat 7 which forms the valve hole 1.2. Under normal state, the movable valve seat 6 and the fixed valve seat 7 are kept separated, and liquefied gas in the steel cylinder can open the one-way valve core 2 for gas supply. When liquefied gas is legally filled, an electromagnetic control device of the intelligent inflating gun is started to generate magnetic force to drive the magnetic control sliding sleeve 4 to slide to the one-way valve element 2, the magnetic control sliding sleeve is inserted into the blocking groove 2.3 to block the movement of the one-way valve element 2, the filled liquefied gas can press the valve seat 6 to be separated from the valve portion 2.1, and the liquefied gas enters the steel cylinder through the central through hole 6.1 and the valve hole 1.2. When illegal charging is carried out, an electromagnetic control device is not triggered to start, the magnetic control sliding sleeve 4 does not act, the liquefied gas can press down the one-way valve core 2 and the movable valve seat 6, the central through hole 6.1 and the valve hole 1.2 are closed, charging is blocked, and illegal charging limiting is realized.

It is to be understood that the drawings provide only a schematic structural view of an embodiment of the smart cylinder valve, in which a movable valve seat 6 is added, in order to improve the sensitivity and reliability of the one-way valve operation by another method. When cancelling moving valve seat 6, one-way valve core 2 also can realize the utility model discloses the invention purpose of intelligence cylinder valve, this type of design is conventional design.

Furthermore, a clamp spring 9 and a seal ring 10 for clamping the iron core 2 are installed between the iron core 2 and the lateral valve body 1.1. Because the iron core 2 is installed and fixed by the clamp spring 9, the clamp spring 9 is completely hidden in the valve body, and an illegal person cannot disassemble the electromagnetic driving unit without damage, and the illegal disassembling prevention function is achieved well unless the illegal disassembling is carried out by violent destructive disassembly.
