[0025] A silent electromagnetic on-off valve for animal breathing, comprising a valve body 1, a valve cover 2, an exhaust connection terminal 3, an air intake connection terminal 4, a detection connection terminal 5, a blind pipe 6, an electromagnetic driver 7 and a valve core component. The valve body 1 is sealed with a valve cover 2, a valve cavity 8 is provided on the valve body 1, an exhaust connection terminal 3 is sealed on the side wall of the valve cavity 8, a blind pipe 6 connected to the valve cavity 8 is sealed on the bottom of the valve cavity 8, an air intake connection terminal 4 and a detection connection terminal 5 are sealed on the blind pipe 6, and the electromagnetic driver 7 is fixedly arranged on the valve body 1, and the output end of the electromagnetic driver 7 passes through the valve cover 2 and is fixedly connected to the valve core component, and the valve core component is sealed with the blind pipe 6 and the valve cover 2. A sealing ring 16 is provided between the valve body 1 and the valve cover 2. The electromagnetic driver 7 is an electromagnet. Among them, the exhaust connection end 3 forms a large airway between the valve body 1 and the blind pipe 6 and the air intake connection end 4. The large airway realizes timely and sufficient exhaust, effectively preventing air accumulation in the animal's lungs and thus affecting the animal's vital signs. The valve body 1 and the valve cover 2 are sealed by a sealing ring 16, and the sealing ring 16 is a rubber sealing ring in the prior art. The electromagnetic drive component 7 is an electromagnet in the prior art. The function of the electromagnetic drive component 7 is to push the valve core component to move in the valve body 1. After the valve core component moves to the side of the valve body 1, the airway will be blocked. The exhaust connection end 3 is not connected to the air intake connection end 4. After the valve core component moves to the side of the valve cover 2, the hole on the valve cover 2 will be blocked. The exhaust connection end 3 and the air intake connection end 4 are connected for exhaust. The air intake connection end 4 can be connected to a gas collection device to realize the collection of exhaust gas. The detection connection end 5 is connected to a detection instrument, so that the gas in the animal experimental cabin can be detected at any time, and the gas pressure change in the blind pipe 6 can also be detected.

[0026] In some embodiments, the valve core component includes a valve stem 9, a locking ring 10, an intermediate disk 11, a first sealing gasket 12 and a second sealing gasket 13. One end of the valve stem 9 is fixedly connected to the output end of the electromagnetic drive member 7, and the intermediate disk 11 is fixedly arranged on the other end of the valve stem 9. The first sealing gasket 12 and the second sealing gasket 13 are respectively fixedly arranged on both sides of the intermediate disk 11. The first sealing gasket 12 and the second sealing gasket 13 are respectively sealed and fixedly arranged on the valve stem 9 through the locking ring 10. The intermediate disk 11, the first sealing gasket 12 and the second sealing gasket 13 are all coaxially fixedly arranged on the valve stem 9, and the valve stem 9 is coaxially arranged with the blind pipe 6. Among them, the first sealing gasket 12 and the second sealing gasket 13 are both elastic rubber materials in the prior art. The first sealing gasket 12 plays a sealing role after contacting the valve body 1, and the second sealing gasket 13 plays a sealing role when contacting the valve cover 2. The valve stem 9 is used to install the locking ring 10, the intermediate disk 11, the first sealing gasket 12 and the second sealing gasket 13. The intermediate disk 11 is a rigid intermediate disk in the prior art. The function of the intermediate disk is to prevent the first sealing gasket 12 and the second sealing gasket 13 from being deformed during the sealing process. The function of the locking ring 10 is to fix the first sealing gasket 12 and the second sealing gasket 13 on the valve stem 9 and prevent the first sealing gasket 12 and the second sealing gasket 13 from moving on the valve stem 9. The valve stem 9 is coaxially fixedly connected to the output shaft of the electromagnetic drive component 7.

[0027] In some embodiments, a first sealing convex ring 14 that seals with the valve body 1 is fixedly provided on the first sealing gasket 12, and a second sealing convex ring 15 that seals with the valve cover 2 is fixedly provided on the second sealing gasket 13. The first sealing convex ring 14 and the second sealing convex ring 15 are both made of elastic rubber materials in the prior art, the first sealing gasket 12 and the first sealing convex ring 14 are integrally formed, and the second sealing gasket 13 and the second sealing convex ring 15 are integrally formed. After the valve core component moves toward the valve body 1 side, the first sealing convex ring 14 can seal with the valve body 1, and after the valve core component moves toward the valve cover 2 side, the second sealing convex ring 15 can seal with the valve cover 2. No noise is generated when the first sealing convex ring 14 contacts the valve body 1, and no noise is generated when the second sealing convex ring 15 contacts the valve cover 2, so that the electromagnetic on-off valve has a better noise reduction effect.

[0028] In some embodiments, a compression ring 19 is disposed between the first gasket 12, the second gasket 13 and the locking ring 10. The compression ring 19 is a rigid compression ring in the prior art, and the compression ring 19 is used to press on the first gasket 12 and the second gasket 13 to prevent the first gasket 12 and the second gasket 13 from being deformed and unable to seal during use.

[0029] In some embodiments, the valve stem 9 is threadedly matched with the locking ring 10. The valve stem 9 and the locking ring 10 are threadedly connected to facilitate disassembly and installation, so that the first sealing gasket 12 and the second sealing gasket 13 are easily replaced.

[0030] In some embodiments, the valve cover 2 is fixed to the valve body 1 by a first screw 17, and the electromagnetic driver 7 is fixed to the valve body 1 by a second screw 18. The first screw 17 and the second screw 18 are both screws in the prior art, and the screw connection facilitates disassembly and subsequent maintenance.

[0031] In some embodiments, the valve body 1, the exhaust connection end 3, the intake connection end 4, the detection connection end 5 and the blind pipe 6 are integrally formed. Such an integrally formed setting reduces the processing of parts, the setting of sealing rings, the processing steps, the risk of air leakage, and also reduces the manufacturing cost.
