Description

Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a one-way valve for water-cooled heat dissipation of a CO2 laser tube. Background Technique

[0002] A laser tube, the full name is a glass-encapsulated CO2 laser. Because its structure is encapsulated by a glass tube, it is commonly known as a laser tube. The main working substances are composed of three gases: CO2, nitrogen, and helium. Among them, CO2 is the gas that generates laser radiation, and nitrogen and helium are auxiliary gases. In a laser tube, a DC current of dozens of mA or hundreds of mA is usually input. During discharge, the nitrogen molecules in the mixed gas in the laser tube are excited due to being hit by electrons. At this time, the excited nitrogen molecules collide with CO2 molecules, and the N2 molecules transfer their energy to the CO2 molecules, and the CO2 molecules transition from a low energy level to a high energy level to form a population inversion and emit laser light.

[0003] Most of the existing laser tubes need to be cooled by water to enable continuous laser emission. When water-cooled heat dissipation is required, a check valve is used to conduct unidirectionally to prevent hot water from flowing back.

[0004] However, the basic principle of the existing check valve still relies on a reset structure such as a spring to push the plug back to block the water flow from flowing back. During use, first, when the water flow pushes the plug open, it is easy to form a water hammer effect at the end of the pipeline and damage the pipeline. On the other hand, due to the influence of gravity on the water flow, the thrust acting on the plug is uneven, which easily causes the spring to bend and deform. When the water flow flows back and the plug is reset, it is easy to generate gaps, resulting in the defect of water leakage in the one-way conduction and poor one-way conduction effect. Therefore, a one-way valve for water-cooled heat dissipation of a CO2 laser tube is proposed to solve the above-mentioned problems. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a one-way valve for water-cooled heat dissipation of a CO2 laser tube, which has the advantages of good one-way conduction effect, etc., and solves the problems that when the water flow pushes the plug open, it is easy to form a water hammer effect at the end of the pipeline and damage the pipeline. On the other hand, due to the influence of gravity on the water flow, the thrust acting on the plug is uneven, which easily causes the spring to bend and deform. When the water flow flows back and the plug is reset, it is easy to generate gaps, resulting in the defect of water leakage in the one-way conduction and poor one-way conduction effect.

[0007] (2) Technical Solutions

[0008] The technical solution of the present utility model to solve the above technical problems is as follows: A one-way valve for water-cooled heat dissipation of a CO laser tube, including a laser tube, a valve housing is connected to the top of the laser tube, a one-way plug is slidably connected inside the valve housing, and a support assembly is fixedly connected between the right side of the one-way plug and the right inner wall of the valve housing cavity. A reset assembly is fixedly connected between the right side of the one-way plug and the right inner wall of the valve housing cavity and is located inside the support assembly;

[0009] The support assembly includes two snap rings. The two snap rings are respectively fixedly connected to the right side of the one-way plug and the right inner wall of the valve housing cavity. The two snap rings are symmetrically distributed left and right. Four blocks are fixedly connected to the outside of the one-way plug and are evenly distributed in a circular shape at equal intervals. The right sides of the four blocks are fixedly connected to the left side of one of the snap rings. Four reed pieces are clamped on the opposite sides of the two snap rings and are evenly distributed in a circular shape at equal intervals. The four reed pieces are on the same axis as the four blocks respectively;

[0010] The reset assembly includes a fixed ring. The fixed ring is arranged between the four reed pieces. Four support rods are fixedly connected between the right side of the fixed ring and the right inner wall of the valve housing cavity and are evenly distributed in a circular shape at equal intervals. Limiting gaskets are fixedly connected to the left side of the fixed ring and the right side of the one-way plug respectively. A same spring is fixedly connected between the two limiting gaskets.

[0011] The beneficial effect of the present utility model is that the support assembly forms a circular supporting force on the one-way plug, so that when it is opened under force, it will not be skewed due to uneven force. The quartz sand in the one-way plug will spread instantly when impacted by water flow, and the quartz sand will spread to evenly disperse the impact force to the entire surface of the one-way plug as much as possible to avoid the occurrence of water hammer effect. The reset device can timely reset the one-way plug when the water returns, blocking the water inlet pipe.

[0012] This one-way valve for water-cooled heat dissipation of a CO laser tube has the advantage of good one-way conduction effect.

[0013] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0014] Further, the laser tube includes a gas storage tube, a water-cooling tube is arranged inside the gas storage tube, one end of the water-cooling tube is fixedly connected to an electrode cylinder, an inner tube fixedly connected to the gas storage tube is fixedly connected to the outside of the electrode cylinder, the water-cooling tube is a sandwich hollow tube, a discharge channel is arranged inside the water-cooling tube, a drainage tube is connected to the outside of the water-cooling tube and extends to the outside of the gas storage tube at one end, and the top of the drainage tube is connected to the inside of the valve housing through a water guide tube.

[0015] The beneficial effect of adopting the above further solution is that the laser tube is used to refract the laser, and the drainage tube is arranged in a spiral shape, which can store as much cold water as possible for standby.

[0016] Furthermore, the one-way plug includes a chassis. A sand shell is fixedly connected to the left side of the chassis. The sand shell is hollow. A pipe plug is fixedly connected to the left side of the sand shell. A rubber pad located outside the sand shell is fixedly connected to the left side of the chassis. The pipe plug is made of rubber.

[0017] The beneficial effect of adopting the above further solution is that rubber has good sealing performance and can fill and seal the gap of the pipe interface when the one-way plug resets to block the water inlet pipe.

[0018] Furthermore, half of the interior of the sand shell is filled with quartz sand. The sand shell is trapezoid-shaped. Water guide channels are opened at both the left and right ends of the valve shell.

[0019] The beneficial effect of adopting the above further solution is that quartz sand has fluidity and can spread when the water flow impacts the one-way plug, enabling it to absorb the impact force and evenly distribute the impact force to the whole one-way plug as much as possible.

[0020] Furthermore, the four reed pieces are all arc-shaped, and the outer sides of the four reed pieces are chromium-plated.

[0021] The beneficial effect of adopting the above further solution is that the chromium-plated reed pieces are not easy to rust and can improve the service life.

[0022] Furthermore, limiting grooves adapted to the springs are opened on the opposite sides of the two limiting gaskets. Water passing holes are opened on the inner sides of the right limiting gasket and the fixing ring.

[0023] The beneficial effect of adopting the above further solution is that the water passing holes can greatly increase the water flow space and improve the water flow rate. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In the embodiment, it is given by Figures 1-4 A one-way valve for water cooling and heat dissipation of a CO2 laser tube. The present invention includes a laser tube 1. The top of the laser tube 1 is communicated with a valve housing 2. A one-way plug 3 is slidably connected inside the valve housing 2. The right side of the one-way plug 3 and the right inner wall of the valve housing 2 are fixedly connected with the same support assembly 4. The right side of the one-way plug 3 and the right inner wall of the valve housing 2 are fixedly connected with the same and a reset assembly 5 located inside the support assembly 4;

[0031] The support assembly 4 includes two snap rings 401. The two snap rings 401 are respectively fixedly connected to the right side of the one-way plug 3 and the right inner wall of the valve housing 2. The two snap rings 401 are symmetrically distributed left and right. The outer side of the one-way plug 3 is fixedly connected with four stop blocks 402 that are equally distributed in a ring shape at equal intervals. The right sides of the four stop blocks 402 are fixedly connected to the left side of one of the snap rings 401. Four reeds 403 that are equally distributed in a ring shape at equal intervals are clamped between the opposite sides of the two snap rings 401. The four reeds 403 are respectively on the same axis as the four stop blocks 402;

[0032] The reset assembly 5 includes a fixed ring 501. The fixed ring 501 is arranged between the four reeds 403. Four support rods 502 that are equally distributed in a ring shape at equal intervals are fixedly connected between the right side of the fixed ring 501 and the right inner wall of the valve housing 2. Limit gaskets 503 are fixedly connected to both the left side of the fixed ring 501 and the right side of the one-way plug 3. The same spring 504 is fixedly connected between the two limit gaskets 503;

[0033] The laser tube 1 includes a gas storage tube 101. Inside the gas storage tube 101, there is a water cooling tube 102. One end of the water cooling tube 102 is fixedly connected to an electrode cylinder 103. Outside the electrode cylinder 103, there is an inner tube 104 fixedly connected to the gas storage tube 101. The water cooling tube 102 is a sandwich hollow tube. Inside the water cooling tube 102, there is a discharge channel 105. Outside the water cooling tube 102, there is a drainage tube 106 whose one end extends to the outside of the gas storage tube 101. The top of the drainage tube 106 is connected to the inside of the valve housing 2 through a water conduit 107.

[0034] The laser tube 1 is used for refracting laser. The drainage tube 106 is arranged in a spiral shape, which can store as much cold water as possible for standby.

[0035] The one-way plug 3 includes a chassis 301. On the left side of the chassis 301, there is a sand shell 302 which is hollow. On the left side of the sand shell 302, there is a pipe plug 303. On the left side of the chassis 301, there is a rubber pad located outside the sand shell 302. The pipe plug 303 is made of rubber.

[0036] Rubber has good sealing performance and can fill and seal the pipe interface gap when the one-way plug 3 resets to block the water inlet pipe.

[0037] Half of the inside of the sand shell 302 is filled with quartz sand 304. The sand shell 302 is trapezoid-shaped. Water guiding channels are opened at both the left and right ends of the valve housing 2.

[0038] The quartz sand 304 has fluidity and can spread when the water flow impacts the one-way plug 3, enabling it to absorb the impact force and evenly distribute the impact force to the whole one-way plug 3 as much as possible.

[0039] All four reed pieces 403 are arc-shaped, and the outside of all four reed pieces 403 is chrome-plated.

[0040] The chrome-plated reed pieces 403 are not easy to rust and can extend the service life.

[0041] On the opposite sides of the two limiting gaskets 503, there are limiting grooves adapted to the spring 504. Water passing holes 6 are opened on the inner sides of the right limiting gasket 503 and the fixing ring 501.

[0042] The water passing holes 6 can greatly increase the water flow circulation space and improve the water flow rate.

[0043] Working principle:

[0044] The first step: Cold water enters the valve housing 2 from the left side of the valve housing 2. When the water flow enters the valve housing 2, it first contacts the surface of the pipe plug 303 to form a thrust. When the water flow impacts the one-way plug 3, the quartz sand 304 is shaken loose and diffuses within the sand shell 302, spreading the impact force of the water flow across the entire one-way plug 3;

[0045] The second step: When the one-way plug 3 moves to the right to open the water inlet channel, the chassis 301 squeezes the spring 504 to contract, allowing the water flow to enter the water guide pipe 107 through the valve housing 2. At the same time, the reed 403 forms a supporting force around the chassis 301 to prevent it from tilting excessively. Then the water flow enters the water cooling pipe 102 through the drainage pipe 106 to absorb the heat in the gas storage pipe 101;

[0046] The third step: After the water inlet is closed and the water flow generates a backflow, the thrust of the backflowing water combined with the thrust of the spring 504 causes the one-way plug 3 to move to the left, making the pipe plug 303 plug into the water inlet pipe. At the same time, the chassis 301 contacts the left inner wall of the valve housing 2, and the gap between the chassis 301 and the valve housing 2 is filled through the rubber pad. Also, the reed 403 can form a thrust on the outside of the chassis 301 to make it completely sealed, preventing the generation of gaps and water leakage, thereby achieving one-way conduction.
