Embodiment 1

[0029] Such as figure 1 As shown, the present invention discloses an intelligent one-way valve, wherein the intelligent one-way valve includes a valve body 1 , a valve core 2 , a push rod 3 and a solenoid valve 5 .

[0030] The valve body 1 is provided with a liquid inlet 101 and a liquid outlet 102, the liquid inlet 101 is connected to the outlet of the natural gas equipment, and the liquid outlet 102 is connected to the equipment to be filled.

[0031] There is a sealing port 103 inside the valve body 1, and the opening direction of the sealing port 103 faces the liquid outlet 102. The valve core 2 can press the sealing port 103 to seal its opening, that is, the liquid natural gas can open the seal from the liquid inlet 101 to the liquid outlet 102. port 103, but the sealing port 103 cannot be opened from the liquid outlet 102 to the liquid inlet 101 direction.

[0032] The first end of the push rod 3 is connected to the valve core 2, and the first spring 4 is covered on th...

Embodiment 2

[0036] In the second embodiment provided by the present invention, the smart one-way valve in this embodiment is similar in structure to the smart one-way valve in the first embodiment, so the similarities will not be repeated, and only the differences will be introduced.

[0037] In this embodiment, it is specifically disclosed that the smart one-way valve also includes a cloud system. Among them, the natural gas equipment installed with the smart check valve is provided with an identification code. After the identification code is identified, the cloud system can authorize the electronic control device on the solenoid valve 5 to control the solenoid valve 5 to be energized, further enhancing the anti-theft performance.

[0038] Furthermore, the present invention discloses that the smart one-way valve further includes a second spring 6, the second spring 6 is in a compressed state, the second spring 6 is covered on the push rod 3, and the bottom end of the second spring 6 is i...

Embodiment 3

[0050]In the third embodiment provided by the present invention, the smart one-way valve in this embodiment is similar in structure to the smart one-way valve in the second embodiment, so the similarities will not be repeated, and only the differences will be introduced.

[0051] In this embodiment, it is specifically disclosed that the sealing port 103 is a tapered port, and the end of the push rod 3 sealing the sealing port 103 is tapered, which can fit with the tapered port to avoid liquid leakage.

[0052] In the present invention, "first", "second", etc. are for distinction in description, and have no other special meanings.

Abstract

The invention discloses an intelligent one-way valve. The intelligent one-way valve comprises a valve body. The valve body is provided with a liquid inlet and a liquid outlet. A valve element, a pushrod and an electromagnetic valve are further included. A seal port is formed in the valve body, the opening direction of the seal port is arranged towards the liquid outlet, and the valve element cantightly press an opening of the seal port. The first end of the push rod is connected with the valve element, the push rod is sleeved with a first spring, the first spring is in a compressed state, the bottom end of the first spring abuts against the top end of the valve element, and the top end of the first spring abuts against the inner top face of the valve body. A piston of the electromagneticvalve is pressed at the top end of the push rod. When the electromagnetic valve is powered on, the piston is moved away so that the push rod can ascend. When the electromagnetic valve is powered off,the piston moves and is pressed at the top end of the push rod. Even when a gas source is externally connected, under the action that the piston is pressed on the push rod, opening of the valve element cannot be achieved, other people are prevented from filling natural gas into natural gas utilization equipment comprising the disclosed intelligent one-way valve, and accordingly other people are prevented from stealing and using the natural gas utilization equipment.

Description

technical field [0001] The invention relates to the technical field of equipment for using liquefied natural gas, in particular to an intelligent check valve. Background technique [0002] With the widespread application of LNG (liquefied natural gas), the number of LNG customers is increasing. At present, LNG filling is carried out to customers through natural gas equipment. [0003] Existing natural gas equipment uses pneumatic valves to control its filling with natural gas. However, when the natural gas equipment is connected to an external gas source, the pneumatic valve can be opened, which makes the natural gas equipment easy to be stolen. [0004] Therefore, how to prevent natural gas equipment from being stolen is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] In view of this, the object of the present invention is to provide an intelligent one-way valve to prevent natural gas equipment from being stolen...
