[0002] Valves are control components in fluid delivery systems and have functions such as cutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in water delivery control systems will, during the water delivery process, allow fine sand in the water to flow directly from the open valve into the household water-using devices along with the water flow. These fine sands will be in the water-using devices. As the water-using devices are opened and closed, the friction between the water-using devices will accelerate the wear and tear, and the loss of the water-using devices will be accelerated. In addition, the water pressure in residential areas may be unstable sometimes, and the water pressure passing through the valve may be sometimes large and sometimes small. This may cause the water-using devices to be suddenly subjected to unstable water pressure shocks, causing damage to the water-using devices. Summary of the invention

[0003] In order to solve the above technical problems, a multi-stage pressure-reducing drain regulating valve is provided. The technical solution solves the problem proposed in the above background technology that fine sand existing in the water flow flowing in the drain regulating valve flows into the indoor water-using device, causing wear and damage to the water-using device, and the water flow through the drain regulating valve sometimes increases and sometimes decreases, causing sudden impact and damage to indoor water pipes and water-using devices, and also solves the problem of uncontrollable water flow size.

Specific implementation mode

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figure 1 , Figure 2 , Figure 5 As shown, a multi-stage pressure-reducing steam trap valve includes: a valve body 1, a sewage discharge seat 2 is movably connected to the bottom of the valve body 1, a lead screw 3 is fixedly connected to the upper end of the sewage discharge seat 2, the lower end of the lead screw 3 penetrates and is fixedly connected to a filter cup 4, the middle part of the lead screw 3 penetrates and is connected to a cleaning device 5, a first bevel gear 6 is fixedly connected to the top end of the cleaning device 5, a water stop part 7 is fixedly connected to the upper part of the middle part of the lead screw 3, a rotating handle 8 is fixedly connected to the top end of the lead screw 3, a rotating device 10 is meshed and connected to the left end of the first bevel gear 6, a fixing bracket 11 is rotatably connected to the middle part of the rotating device 10, and an adjusting device 12 is fixedly connected to the right end of the rotating device 10;

[0026] The cleaning device 5 includes: a rotating cylinder 51, a plurality of connecting rods 52, and a plurality of cleaning parts 53. The outer wall of the rotating cylinder 51 is fixedly connected to the connecting rod 52, the connecting rod 52 is fixedly connected to the cleaning part 53, and the rotating cylinder 51 penetrates and is rotatably connected to the lead screw 3.

[0027] Working principle: first, rotate the rotating handle 8 counterclockwise by hand, and the rotation of the rotating handle 8 drives the water stop core 72 in the water stop member 7 to move upward. When the upper end of the water stop core 72 hits the upper wall inside the valve body 1, stop the rotation of the rotating handle 8. When the rotating handle 8 stops rotating, the width and height of the water stop core 72 are greater than the width and height of the water inlet inside the valve body 1. A large amount of water will flow into the water inlet at the left end of the valve body 1, and the water flowing in from the water inlet will directly rush to the filter cup 4. Because the cup wall of the filter cup 4 is set to be hollow, and a large number of dense small through holes are evenly distributed on the cup wall, when the water flow rushes to the small holes on the cup wall, the evenly distributed small holes in the filter cup 4 will filter out the fine sand entrained in the water flowing in from the inlet end, and part of the water flow will flow from the left end of the filter cup 4 to the outlet through filtration, and part of the water flow will rush from the lower part of the filter cup 4 to the rotary inner wall set inside the valve body 1. Part of the water flow is filtered from the right side of the filter cup 4 and flows to the water outlet. This design can fully filter the water flow, filter the fine sand entrained by the water flowing in from the water inlet end, and ensure that the water flow at the water outlet entrains fine sand, and the fine sand filtered by the filter cup 4 will accumulate on the sewage discharge seat 2 set at the bottom of the filter cup 4. Since the filter cup 4 often filters fine sand, the small holes distributed on the wall of the filter cup 4 sometimes get stuck with some fine sand when filtering the water flow. At this time, the cleaning device 5 will rotate under the impact of the water flow at the water inlet end. The outer end surface of the cleaning member 53 in the cleaning device 5 is provided with a brush. The cleaning member 53 can brush the small holes of the filter cup 4 in the process of being pushed by the water flow. The fine sand stuck in the small holes is cleaned out of the small holes by the brushing of the cleaning member 53, thus avoiding the filter cup 4 being blocked by fine sand and affecting the output of the water flow from the water inlet of the valve body 1 to the water outlet.

[0028] Embodiment 2

[0029] Please refer to Figure 3 and Figure 4 As shown, the water stop member 7 includes: an anti-rotation shaft rod 71 and a water stop core 72 . The right side of the water stop core 72 is fixedly connected to the anti-rotation shaft rod 71 , and the right side of the anti-rotation shaft rod 71 is fixedly connected to the screw rod 3 .

[0030] A rubber pad 711 is provided on the left side wall of the water stop core 72 , and a rubber ring is provided on the outer wall of the sewage discharge seat 2 .

[0031] Working principle: When it is necessary to cut off the water flow, rotate the rotating handle 8 clockwise by hand. The rotating rotating handle 8 drives the lead screw 3 to rotate. The rotation of the lead screw 3 drives the anti-rotating shaft rod 71 to move downward. A bearing is provided at the connection end of the anti-rotating shaft rod 71 and the lead screw 3, and clamping plates are provided on both sides of the bearing. When the lead screw 3 drives the clamping plates to rotate, the middle bearing remains stationary. In this way, when the lead screw 3 rotates, the anti-rotating shaft rod 71 will move up and down without rotating. The downward movement of the anti-rotating shaft rod 71 will drive the water stop core 72 fixedly connected thereto to move downward. When the lower end of the water stop core 72 abuts against the inner lower surface of the valve body 1, stop rotating the rotating handle 8. Because a rubber pad 711 is provided on the left end face of the water stop core 72, at this time, the water stop core 72 can more powerfully block the water flow at the water inlet. During the process of blocking the water inlet, the sewage discharge seat 2 connected to the bottom end of the lead screw 3 also moves downward. When the water flow is completely cut off, the sewage discharge seat 2 is taken out of the valve body 1 by the downward-moving lead screw 3. At this time, the residual water flow inside the valve body 1 will flow downward, and the fine sand accumulated on the sewage discharge seat 2 will be washed clean during the process of the water flow flowing out. The sewage discharge seat 2 can also be manually cleaned.

[0032] Embodiment Three

[0033] Please refer to Figure 5 and Figure 6 As shown, the cleaning device 5 includes: a rotating cylinder 51, a plurality of connecting rods 52, and a plurality of cleaning members 53. The outer wall of the rotating cylinder 51 is fixedly connected to the connecting rod 52, the connecting rod 52 is fixedly connected to the cleaning member 53, and the rotating cylinder 51 is rotatably connected to the lead screw 3 through.

[0034] The adjusting device 12 includes: a plurality of outer flow blocking members 121 and a plurality of inner flow blocking members 122. The inner side of the outer flow blocking member 121 is movably connected to the inner flow blocking member 122, and the inner side of the inner flow blocking member 122 is elastically connected to the rotating device 10.

[0035] The rotating device 10 includes: a cross bar 101 and a second bevel gear 102. The first bevel gear 6 is meshed and connected to the second bevel gear 102. The right end of the second bevel gear 102 is fixedly connected with a cross bar 101. Both ends of the cross bar 101 are fixedly connected to the outer flow blocking member 121, and the inside of the outer flow blocking member 121 is in a cavity shape.

[0036] Working principle: Water flow enters from the water inlet end of the valve body 1. The water flow will impact the cleaning device 5. When the incoming water pressure is strong, the water flow will push the cleaning part 53 in the cleaning device 5 to rotate. When the cleaning part 53 rotates, it will drive the connecting rod 52 fixedly connected to the cleaning part 53 to rotate accordingly. The connecting rod 52 will then drive the rotating cylinder 51 fixedly connected to it to rotate. The rotating cylinder 51 drives the first bevel gear 6 fixedly connected to it to rotate rapidly. The rotation of the first bevel gear 6 drives the rotating device 10 meshed and connected to it to rotate rapidly. The rapidly rotating rotating device 10 drives the adjusting device 12 fixedly connected to it to rotate rapidly. During the rapid rotation of the adjusting device 12, the centrifugal force generated by the internal flow resistance part 122 connected to the rotating device 10 through a spring causes the spring to deform, making the internal flow resistance part 122 retract into the external flow resistance part 121. The retraction of the internal flow resistance part 122 into the external flow resistance part 121 makes the water outlet in the valve body 1 larger, and when the water outlet becomes larger, the water pressure in the valve body 1 becomes smaller.

[0037] When the water flow into the valve body 1 becomes smaller, the impact force of the water flow on the cleaning device 5 becomes smaller, so the rotation speed of the cleaning device 5 slows down. When the rotation speed of the cleaning device 5 slows down, it drives the rotation speed of the first bevel gear 6 to slow down. When the rotation speed of the first bevel gear 6 slows down, the rotation speed of the rotating device 10 meshed with the first bevel gear 6 slows down. The slow rotation of the rotating device 10 drives the rotation speed of the adjusting device 12 fixedly connected to it to slow down. The slow rotation of the adjusting device 12 makes the internal flow resistance part 122 connected to the rotating device 10 through a spring have a weakened centrifugal force during the slow rotation process, and the spring will tighten the internal flow resistance part 122, causing the internal flow resistance part 122 to extend from the inner cavity of the external flow resistance part 121, thereby changing the opening of the water outlet end inside the valve body 1 to become smaller, making the water flow speed inside the valve body 1 faster. Through the above device, the impact damage of the water flow on the indoor water-using device can be changed.

[0038] Embodiment 4

[0039] Please refer to Figure 1 Figure 6 As shown, a multi-stage pressure-reducing steam trap valve includes: a valve body 1. A drain seat 2 is movably connected to the bottom of the valve body 1. A lead screw 3 is fixedly connected to the upper end of the drain seat 2. The lower end of the lead screw 3 penetrates and is fixedly connected to a filter cup 4. The middle part of the lead screw 3 penetrates and is connected to a cleaning device 5. The top end of the cleaning device 5 is fixedly connected with a first bevel gear 6. A water stop part 7 is fixedly connected to the upper part of the middle of the lead screw 3. A rotating handle 8 is fixedly connected to the top end of the lead screw 3. The left end of the first bevel gear 6 is meshed and connected with a rotating device 10. The middle part of the rotating device 10 is rotationally connected to a fixed frame 11. The right end of the rotating device 10 is fixedly connected with an adjusting device 12.

[0040] The cleaning device 5 includes: a rotating cylinder 51, a plurality of connecting rods 52, and a plurality of cleaning members 53. The outer wall of the rotating cylinder 51 is fixedly connected to the connecting rods 52, and the connecting rods 52 are fixedly connected to the cleaning members 53. The rotating cylinder 51 is rotatably connected to the lead screw 3 through it.

[0041] The adjusting device 12 includes: a plurality of outer flow restrictors 121 and a plurality of inner flow restrictors 122. The inner side of the outer flow restrictor 121 is movably connected to the inner flow restrictor 122, and the inner side of the inner flow restrictor 122 is elastically connected to the rotating device 10.

[0042] The rotating device 10 includes: a cross bar 101 and a second bevel gear 102. The first bevel gear 6 is meshed with the second bevel gear 102. The right end of the second bevel gear 102 is fixedly connected to a cross bar 101. The two ends of the cross bar 101 are fixedly connected to the outer flow restrictors 121, and the inside of the outer flow restrictors 121 is cavity-shaped.

[0043] The water stop member 7 includes: a water stop shaft rod 71 and a water stop core 72. The right side of the water stop core 72 is fixedly connected to the water stop shaft rod 71, and the right side of the water stop shaft rod 71 is fixedly connected to the lead screw 3.

[0044] A rubber pad 711 is provided on the left side wall of the water stop core 72, and a rubber ring is provided on the outer wall of the sewage seat 2.

[0045] Working principle: first, rotate the rotating handle 8 counterclockwise by hand, and the rotation of the rotating handle 8 drives the water stop core 72 in the water stop member 7 to move upward. When the upper end of the water stop core 72 hits the upper wall inside the valve body 1, stop the rotation of the rotating handle 8. When the rotating handle 8 stops rotating, the width and height of the water stop core 72 are greater than the width and height of the water inlet inside the valve body 1. A large amount of water will flow into the water inlet at the left end of the valve body 1, and the water flowing in from the water inlet will directly rush to the filter cup 4. Because the cup wall of the filter cup 4 is set to be hollow, and a large number of dense small through holes are evenly distributed on the cup wall, when the water flow rushes to the small holes on the cup wall, the evenly distributed small holes in the filter cup 4 will filter out the fine sand entrained in the water flowing in from the inlet end, and part of the water flow will flow from the left end of the filter cup 4 to the outlet through filtration, and part of the water flow will rush from the lower part of the filter cup 4 to the rotary inner wall set inside the valve body 1. Part of the water flow is filtered from the right side of the filter cup 4 and flows to the water outlet. This design can fully filter the water flow, filter the fine sand entrained by the water flowing in from the water inlet end, and ensure that the water flow at the water outlet entrains fine sand, and the fine sand filtered by the filter cup 4 will accumulate on the sewage discharge seat 2 set at the bottom of the filter cup 4. Since the filter cup 4 often filters fine sand, the small holes distributed on the wall of the filter cup 4 sometimes get stuck with some fine sand when filtering the water flow. At this time, the cleaning device 5 will rotate under the impact of the water flow at the water inlet end. The outer end surface of the cleaning member 53 in the cleaning device 5 is provided with a brush. The cleaning member 53 can brush the small holes of the filter cup 4 in the process of being pushed by the water flow. The fine sand stuck in the small holes is cleaned out of the small holes by the brushing of the cleaning member 53, thus avoiding the filter cup 4 being blocked by fine sand and affecting the output of the water flow from the water inlet of the valve body 1 to the water outlet.

[0046] When it is necessary to cut off the water flow, the rotating handle 8 is rotated clockwise by hand. The rotating rotating handle 8 drives the screw rod 3 to rotate. The rotation of the screw rod 3 drives the anti-rotation shaft rod 71 to move downward. A bearing is provided at the connecting end of the anti-rotation shaft rod 71 and the screw rod 3. Clamps are provided on the upper and lower sides of the bearing. When the screw rod 3 drives the clamping plate to rotate, the middle bearing remains stationary. In this way, when the screw rod 3 rotates, the anti-rotation shaft rod 71 will move up and down without rotating. The downward movement of the anti-rotation shaft rod 71 will drive the water stop core 72 fixedly connected to it to move downward. When the lower end of the water stop core 72 hits the lower surface of the inner part of the valve body 1, the rotation stops. Handle 8, because the rubber pad 711 is provided on the left end face of the water stop core 72, at this time, the water stop core 72 can more forcefully block the water flow of the water inlet, and in the process of blocking the water inlet, the drain seat 2 connected to the bottom end of the screw rod 3 also moves downward, and the port of the drain seat 2 is provided with a thick layer of rubber material, which can better seal the valve body 1 in the closed state. When the water flow is completely cut off, the drain seat 2 is brought out of the valve body 1 by the downward-moving screw rod 3. At this time, the remaining water flow in the valve body 1 will flow downward, and the fine sand accumulated on the drain seat 2 will be flushed clean in the process of water flowing out, and the drain seat 2 can also be cleaned manually.

[0047] Rotate the rotating handle 8 counterclockwise by hand, and the water stop core 72 will move upward until the opening is completely opened. Then, water will flow in from the water inlet of the valve body 1. The inflowing water will impact the cleaning device 5. When the flow rate of the water is strong, the water will push the cleaning part 53 in the cleaning device 5 to rotate rapidly. When the cleaning part 53 rotates rapidly, it will drive the connecting rod 52 fixedly connected to the cleaning part 53 to rotate rapidly. The connecting rod 52 will drive the rotating cylinder 51 fixedly connected to it to rotate rapidly. The rotating cylinder 51 will drive the first bevel gear 6 fixedly connected to it to rotate rapidly. The rotation of the first bevel gear 6 will drive the rotating device 10 meshed with it to rotate rapidly. The rapidly rotating rotating device 10 will drive the adjusting device 12 fixedly connected to it to rotate rapidly. At this time, the rapidly rotating adjusting device 12 will generate a strong centrifugal force. The internal flow resistance part 122 connected to the rotating device 10 through a spring. During the rapid rotation of the internal flow resistance part 122 connected to the rotating device 10 through a spring, since the inside of the external flow resistance part 121 is a cavity, the centrifugal force generated by the rapidly rotating rotating device 10 deforms the spring and makes the internal flow resistance part 122 retract into the internal part of the external flow resistance part 121. The retraction of the internal flow resistance part 122 into the internal part of the external flow resistance part 121 makes the water outlet in the valve body 1 larger. When the water outlet becomes larger, the water pressure in the valve body 1 becomes smaller.

[0048] When the water flowing into the water inlet of the valve body 1 becomes smaller, at this time, the impact force of the water on the cleaning device 5 becomes smaller, so the rotation speed of the cleaning device 5 slows down. When the rotation speed of the cleaning device 5 slows down, the rotation speed of the first bevel gear 6 driven by it also slows down. When the rotation speed of the first bevel gear 6 slows down, the rotation speed of the rotating device 10 meshed with the first bevel gear 6 slows down. The slow rotation of the rotating device 10 drives the adjusting device 12 fixedly connected to it to slow down. The slow rotation of the adjusting device 12 makes the centrifugal force of the internal flow resistance part 122 connected to the rotating device 10 through a spring weaken during the slow rotation process. At this time, the spring will tighten the internal flow resistance part 122 to pull the internal flow resistance part 122 out of the cavity of the external flow resistance part 121, thereby changing the opening of the water outlet in the valve body 1 to become smaller. When the opening becomes smaller, the water flow in the valve body 1 will become faster. Through the above set of devices, when the water flow at the water inlet is relatively fast, the water outlet of the valve body 1 can be made larger to slow down the water flow speed. When the water flow at the water inlet slows down, the water outlet of the valve body 1 becomes smaller to increase the water flow speed, so as to adjust the speed of the water flow and reduce the damage caused by the sudden increase or decrease of the water flow to the indoor water-using devices.
