[0002] With the rapid development of new energy vehicle models, the intelligent control of automobiles is becoming more and more flexible and advanced. The increase in electronic components and control circuits has led to higher and higher heat dissipation requirements for new energy vehicle models. Automobile thermal management is becoming more and more important. When the existing new energy vehicle thermal management coolant system is working, due to the large number of system circuits and staggered connections, many components are connected in series, and the layout of each component spans all corners of the vehicle from the front cabin to the trunk. The entire interconnected circuit is complex, making exhaust very difficult, especially when adding coolant to the system or replacing parts in the system circuit, water cross-talk is prone to occur, resulting in system abnormalities. Utility Model Content
[0003] The utility model provides a degassing valve, which aims to realize the opening or closing of a degassing pipeline.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A degassing valve, an air inlet pipe and an exhaust pipe are arranged on the valve body, the inner ends of the air inlet pipe and the exhaust pipe are radially connected to the cylindrical valve cavity in the valve body, the cylindrical valve core is inserted in the valve cavity and the valve core and the valve cavity are arranged coaxially, a through hole is provided on the valve core which passes through in the radial direction, a sealing ring is arranged around the hole area where the cavity wall of the inner ends of the air inlet pipe and the exhaust pipe and the cavity wall of the valve cavity pass through, the sealing ring and the valve core form an abutting fit, a rotating handle connected to the axial end of the valve core is exposed on the outside of the valve body, and when the valve core rotates, the through hole is in a conducting position connected to the air inlet pipe and the exhaust pipe or in a misaligned avoidance position with the air inlet pipe and the exhaust pipe.

[0011] like Figures 1 to 4 A degassing valve is shown, and an air inlet pipe 12 and an exhaust pipe 13 are provided on the valve body 10. The inner ends of the air inlet pipe 12 and the exhaust pipe 13 are radially connected to the cylindrical valve cavity 11 in the valve body 10. The cylindrical valve core 20 is inserted in the valve cavity 11 and the valve core 20 and the valve cavity 11 are arranged coaxially. A through hole 24 is provided on the valve core 20 and passes through in the radial direction. A sealing ring 40 is provided around the hole area where the cavity wall of the inner end of the air inlet pipe 12 and the exhaust pipe 13 and the cavity wall of the valve cavity 11 pass through. The sealing ring 40 and the valve core 20 form an abutting fit. The rotary handle 30 connected to the axial end of the valve core 20 is exposed outside the valve body 10. When the valve core 20 rotates, the through hole 24 is in a conducting position connected to the air inlet pipe 12 and the exhaust pipe 13 or in a staggered avoidance position with the air inlet pipe 12 and the exhaust pipe 13.
[0012] In the above scheme, the inner ends of the intake pipe 12 and the exhaust pipe 13 are radially connected to the cylindrical valve cavity 11 in the valve body 10, and the cylindrical valve core 20 is inserted in the valve cavity 11. A sealing ring is arranged between the valve cavity 11 and the valve core 20, and a through hole 24 is arranged on the valve core 20. When the automobile is in normal working condition, the valve core 20 is rotated so that the through hole 24 is in a staggered avoidance position with the intake pipe 12 and the exhaust pipe 13, and the connecting channel is closed. When it is necessary to add coolant or replace parts in the system circuit, the valve core 20 is rotated so that the through hole 24 is in a conducting position connecting the intake pipe 12 and the exhaust pipe 13 to achieve conduction.
[0013] Furthermore, the handle 30 is disc-shaped, and the edge of the handle 30 has a claw 31 protruding toward the outer wall of the valve cavity 11. The claw 31 includes an arc-shaped strip-shaped claw leg 311 connected to the handle 30, and the free end of the arc-shaped strip-shaped claw leg 311 has a claw portion 312 protruding radially inward, and the cross-section of the claw 31 is "L"-shaped as a whole. The cavity of the valve cavity 11 is a large-diameter section 111, and the edge of the large-diameter section 111 abuts against the inner disk surface of the handle 30, and the claw portion 312 abuts against the lower surface of the transition table 112 between the large-diameter section 111 and the small-diameter section of the valve cavity 11 to form an axial limit clamping fit.
[0014] In the above scheme, a claw 31 is provided on the edge of the handle 30. The claws 31 are two symmetrically arranged claws 31 protruding toward the outer wall of the valve cavity 11. The claws 31 are pressed against the lower surface of the transition table 112 between the large-diameter section 111 and the small-diameter section of the valve cavity 11 to form an axial limit clamping fit, which can not only effectively prevent the axial separation of the valve core 20 and the valve cavity 11, but also ensure the stability of the posture of the valve core 20 during rotation.
[0015] Furthermore, the valve core 20 is a hollow cylindrical shape, and the valve core 20 includes a first step 21, a second step 22, and a third step 23, which are arranged coaxially and have outer diameters that decrease from top to bottom. The first step 21 is consistent with the diameter of the large-diameter section 111 of the valve cavity 11, and the second step 22 is a step with an outer diameter greater than the outer diameter of the valve core 20. The lower circumferential surface of the second step 22 abuts against the upper surface of the transition table 112 of the large-diameter section 111. An annular cavity for accommodating a sealing ring 40 is formed between the first step 21, the second step 22 and the large-diameter section 111 of the valve cavity 11. A sealing ring 40 is provided between the third step 23 and the through-hole of the cavity wall of the valve cavity 11, and the sealing ring 40 and the second step 22 of the valve core 20 form an abutting fit.
[0016] In the above scheme, the valve core 20 is a hollow cylindrical shape, which can avoid pipeline load-bearing and achieve lightweight. The first step 21 connected to the rotary handle 30 is embedded in the large-diameter section 111 of the valve cavity 11, ensuring that the posture of the valve core 20 is stable when the rotary handle 30 rotates. The lower circumference of the second step 22 abuts against the upper surface of the transition table 112 of the large-diameter section 111, which plays a positioning and supporting role for the valve core 20 in the valve cavity 11. The annular cavity is enclosed by the first step 21, the second step 22 and the large-diameter section 111 of the valve cavity 11 to accommodate the sealing ring 40. The sealing ring 40 and the second step 22 of the valve core 20 form an abutting fit, thereby achieving radial sealing and ensuring the sealing effect between the valve cavity 11 and the valve core 20.
[0017] Preferably, in order to facilitate the claw 31 to smoothly reach the lower surface of the transition table 112 to form an axial limit clamping fit, there is a conical chamfer between the upper end of the large-diameter section 111 and the outer wall, and the inner end of the claw 312 is a wedge that cooperates with the conical chamfer.
[0018] Furthermore, in order to facilitate the buckling of the claw 31 and to provide a certain degree of deformation capability, the valve core 20 and the rotary handle 30 are integrally formed plastic parts.
