Description

Technical Field

[0001] The utility model relates to the technical field of pipe valves, in particular to a stainless steel plug-in type high-sealing quick-insertion pipe valve. Background Art

[0002] The quick-insert pipe valve is a valve that is characterized by being made of stainless steel and using a plug-in connection method, which is convenient and quick to install and disassemble. This valve is usually used in pipeline systems, such as pipeline transportation in the food, pharmaceutical, chemical and other industries. The structure of the quick-insert pipe valve is generally composed of a valve body, a valve disc, a sealing ring, a valve stem, etc. Among them, the sealing ring is a key component, which is made of high-quality materials to ensure the sealing performance. The valve stem is made of stainless steel and is precision machined and polished to ensure its matching accuracy and wear resistance with the valve disc. The advantages of the quick-insert pipe valve are its compact structure, good sealing performance, easy use, and high reliability, which can meet various application scenarios with high sealing requirements. In addition, because it uses a plug-in connection method, it can be quickly installed and disassembled, which is convenient for maintenance and replacement, and improves the use efficiency. It is widely used in various pipeline transportation systems, can meet high sealing requirements, and improve the reliability and stability of the pipeline system.

[0003] In the prior art, the purpose of the plug-in and pull-out tube valve is to quickly plug and unplug, facilitate the connection test of the corresponding pipeline, and replace the plug-in interface at any time to ensure that the corresponding test interface completes the test. It is also convenient for maintenance. However, the traditional plug-in and pull-out tube valve usually requires manual pressing of the port of the plug-in and pull-out tube valve during the plug-in and pull-out process to pop open the sealing bayonet inside it, so that the connecting pipeline can be conveniently connected to the plug-in and pull-out tube valve. At the same time, when the pipeline needs to be pulled out, it needs to be pressed again. This type of plug-in and pull-out tube valve often needs to ensure sealing, so it takes a lot of force to manually press the port. At the same time, if the sealing bayonet is frequently popped open by pressing with fingers, it is easy to cause damage to the fingers. Utility Model Content

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of having the functions of easy opening and closing of the bayonet, quick plugging and unplugging, and high sealing, the utility model provides the following technical solutions: a stainless steel plug-in type high-sealing quick-insertion valve, comprising a valve body, a rotating sleeve, a valve core is provided in the middle section of the inner cavity of the valve body, the valve core is connected to the rotary switch, the inlet and outlet ends of the inner cavity of the valve body are provided with a stepped groove, a limit piece is provided in the stepped groove, a magnetic clip is provided on the inner ring of the limit piece, an elastic clip plate is provided on the inner ring of the limit piece located at the lower end of the magnetic clip, a moving opening and closing piece is provided through the magnetic clip, a screw ear is extended outward from the outer ring of the end of the moving opening and closing piece, the screw ear is connected to one end of the pushing screw, and the other end of the pushing screw is connected to a conduction gear arranged in a planetary gear groove, and the planetary gear groove is composed of an inner plate and an outer plate on the rotating sleeve.

[0008] Preferably, the rotating sleeve is sleeved on the outer ring of the inlet and outlet ends of the valve body and is clamped by a limiting plate.

[0009] Preferably, a gear limiting end cover is provided on the planetary gear groove, a screw rod through hole is provided on the gear limiting end cover, and a tensioning spring is provided between the bottom of the planetary gear groove and the conduction gear.

[0011] Preferably, the rotating sleeve is made of non-magnetic material.

[0012] Preferably, the number of the transmission gears is at least three.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a stainless steel plug-in type high-sealing quick-insertion valve, which has the following beneficial effects:

[0015] 1. This stainless steel plug-in high-sealing quick-insertion valve can realize the rapid opening and closing of the elastic clamping plate by rotating the sleeve in conjunction with the moving opening and closing parts, avoiding the need for manual fingers to use greater force to press the elastic port at the end of the valve body for plugging and unplugging in traditional plug-in valves. It can effectively protect the fingers and prevent blood stasis caused by frequent pressing.

[0016] 2. This stainless steel plug-in high-sealing quick-insertion valve can ensure sufficient sealing of the overall air circuit after connecting to the external air pipe through the setting of the elastic clamp plate, and can prevent the risk of leakage after connection. Since the air pipe is pushed to the bottom of the step groove during plugging and unplugging, and the elastic clamp plate adopts a barb structure, the connected air pipe is restricted and fixed, and the air pipe will not move in a fully constrained state. At the same time, the barb structure can effectively prevent accidental pulling out with great force and destroying the air circuit circulation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7A stainless steel plug-in high-sealing quick-insertion valve comprises a valve body 1 and a rotating sleeve 18. A valve core 2 is provided in the middle section of the inner cavity of the valve body 1. The valve core 2 is connected to a rotary switch 3. A stepped groove 4 is provided at the inlet and outlet ends of the inner cavity of the valve body 1. A limiting member 5 is provided in the stepped groove 4. A magnetic clip strip 6 is provided in the inner ring of the limiting member 5. An elastic clip plate 7 is provided on the inner ring of the limiting member 5 at the lower end of the magnetic clip strip 6. A moving opening and closing member 8 is provided through the magnetic clip strip 6. A screw ear 9 extends outward from the outer ring of the end of the moving opening and closing member 8. The screw ear 9 is connected to one end of a pushing screw rod 10. The other end of the pushing screw rod 10 is connected to a conduction gear 11 provided in a planetary gear groove 14. The planetary gear groove 14 is composed of an inner plate 13 and an outer plate 12 on the rotating sleeve 18.

[0027] A valve core 2 is provided in the middle section of the inner cavity of the valve body 1, and the valve core 2 is connected to a rotary switch 3. The opening and closing of the valve core 2 can be controlled by rotating the switch 3. A stepped groove 4 is provided at the inlet and outlet ends of the inner cavity of the valve body 1, and a limiter 5 is provided in the stepped groove 4. A magnetic clamping strip 6 is provided on the inner ring of the limiter 5, and the magnetic clamping strip 6 interacts with the moving opening and closing member 8 to achieve the fixation and movement of the limiter 5. A screw ear 9 extends outward from the outer ring of the end of the moving opening and closing member 8, and the screw ear 9 is connected to one end of the pushing screw 10. The other end of the pushing screw 10 is connected to the transmission gear 11 provided in the planetary gear groove 14. The rotation of the transmission gear 11 drives the movement of the pushing screw 10, thereby realizing the movement of the moving opening and closing member 8. The planetary gear groove 14 is composed of an inner plate 13 and an outer plate 12 on the rotating sleeve 18, and the planetary gear groove 14 is used to fix the transmission gear 11 and rotate with it.

[0028] The valve core 2 is opened and closed by rotating the switch 3 to realize the on-off and flow control of the pipeline. The design of the stepped groove 4 and the limiter 5 improves the sealing performance of the valve and effectively prevents medium leakage. The magnetic card strip 6 in the limiter 5 interacts with the moving opening and closing member 8, making the fixing and movement of the limiter 5 more convenient and quick. The cooperation between the moving opening and closing member 8, the push screw 10 and the transmission gear 11 makes the valve movement more precise and stable. The design of the planetary tooth groove 14 on the rotating sleeve 18 improves the fixation and rotation stability of the transmission gear 11. The stainless steel material ensures the high corrosion resistance and long service life of the valve.

[0029] The rotating sleeve 18 is sleeved on the outer ring of the inlet and outlet ends of the valve body 1 and is clamped by a limiting plate.

[0030] In the stainless steel plug-in high-sealing quick-insert valve, the rotating sleeve 18 is sleeved on the outer ring of the inlet and outlet ends of the valve body 1 and is clamped by a limit plate. This design further enhances the sealing performance and stability of the valve. When the rotating sleeve 18 is sleeved on the outer ring of the inlet and outlet ends of the valve body 1, a tight fit is formed between the rotating sleeve 18 and the valve body 1, which can effectively prevent the medium from leaking from the gap between the rotating sleeve 18 and the valve body 1. In addition, the design of the rotating sleeve 18 can also play a certain protective role on the valve core 2, avoiding direct erosion and corrosion of the valve core 2 by external impurities or fluids. By clamping with the limit plate, the position of the rotating sleeve 18 can be further fixed to ensure its tight fit with the valve body 1. The design of the limit plate can effectively prevent the rotating sleeve 18 from loosening or shifting during operation, thereby ensuring the high sealing performance and stability of the valve. The combination of the rotating sleeve 18 and the limit plate improves the sealing performance and stability of the valve and ensures the reliability and safety of the pipeline system.

[0031] The planetary tooth groove 14 is provided with a gear limiting end cover 15 , the gear limiting end cover 15 is provided with a screw rod through hole 16 , and a tensioning spring 17 is provided between the bottom of the planetary tooth groove 14 and the transmission gear 11 .

[0032] The gear limiting end cover 15 provided on the planetary gear groove 14 mainly limits the position of the transmission gear 11, ensures its stable rotation in the planetary gear groove 14, and prevents it from shifting or falling off. A screw through hole 16 is provided on the gear limiting end cover 15, so that the push screw 10 can pass through the through hole and connect with the transmission gear 11. This design not only ensures the smooth transmission between the screw and the transmission gear 11, but also avoids the friction and wear between the screw and the end cover. A tightening spring 17 is provided between the bottom of the planetary gear groove 14 and the transmission gear 11. The function of the tightening spring 17 is to provide a certain elastic force so that the transmission gear 11 always maintains a certain contact pressure with the bottom of the planetary gear groove 14. This can reduce the vibration and noise during the transmission process to a certain extent, and improve the stability and accuracy of the transmission.

[0033] The outer ring of the rotating sleeve 18 is provided with a magnetic clamping strip 6. The rotating sleeve 18 is made of non-magnetic material. The number of the transmission gears 11 is at least three.

[0034] The magnetic clip strip 6 disposed on the outer ring of the rotating sleeve 18 is used to interact with the magnetic clip strip 6 in the valve body 1 to achieve the fixing and unlocking of the rotating sleeve 18. The design of the magnetic clip strip 6 simplifies the operation process and makes the installation and removal of the rotating sleeve 18 more convenient. In order to ensure that the function of the magnetic clip strip 6 is not affected, the rotating sleeve 18 is made of non-magnetic material. The selection of non-magnetic material avoids magnetic interference and ensures the stable cooperation between the rotating sleeve 18 and the valve body 1. The design of at least three transmission gears 11 increases the stability and reliability of the valve transmission. The coordinated use of multiple transmission gears 11 disperses the force and reduces the load borne by a single gear, thereby extending the service life of the gear.

[0035] Working principle: When an external air pipe is needed, the planetary gear groove 14 drives the gear to rotate by rotating the rotating sleeve 18, so that the screw rod moves laterally, driving the moving opening and closing member 8 to move laterally, so that its end pushes the elastic clamping plate 7 open, and then the air pipe is inserted, and the end of the air pipe is pushed to the bottom of the stepped groove 4. At this time, the rotating sleeve 18 is rotated in the opposite direction to make the moving opening and closing member 8 return to its original position. Since the elastic clamping plate 7 is in a barb shape, the elastic clamping plate 7 can clamp the air pipe, completing the rapid insertion of the air pipe. When the air pipe needs to be pulled out, the rotating sleeve 18 is controlled again to drive the moving opening and closing member 8, so that the elastic clamping plate 7 is pushed open, and the external air pipe can be pulled out.
