Description

Technical Field

[0001] The invention relates to the technical field of valves, in particular to a high-temperature and high-pressure regulating valve. Background Art

[0002] In modern industrial fields, such as petrochemical, electric power, steel and other industries, precise control of high temperature and high pressure fluids is a key link to ensure safe and efficient operation of the production process. As the core component of the fluid control system, the high temperature and high pressure regulating valve is responsible for regulating important parameters such as flow and pressure.

[0003] In many industrial applications, high-temperature and high-pressure water has enormous energy. When the regulating valve is in the process of opening or closing, the flow rate and direction of the water will change dramatically, and the resulting impact force will directly act on the valve body. The instantaneous impact of the water flow may cause cracks, deformation and other structural damage to the valve body. This structural damage will not only cause the regulating valve to fail and cause production interruption, but may also cause serious safety accidents and environmental pollution due to medium leakage.

[0004] In addition, many existing regulating valves lack real-time effective feedback and adaptive adjustment mechanisms for pressure during the flow regulation process. In actual industrial production, the pressure in the pipeline system changes dynamically. They are usually operated according to the preset opening or control signal without fully considering the impact of pressure changes on flow, thus failing to accurately meet the user's usage needs.

[0005] Therefore, the existing high-temperature and high-pressure regulating valves have obvious deficiencies in protecting the valve body from water flow impact and adaptively adjusting the water flow according to pressure, and are unable to meet the increasingly complex and stringent fluid control needs of modern industry. Summary of the invention

[0006] The object of the present invention is to provide a high-temperature and high-pressure regulating valve to solve the problems raised in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The high-temperature and high-pressure regulating valve includes a mounting frame, a valve body, a regulating unit and a protective unit. The mounting frame is placed on a horizontal foundation. The valve body is fixedly connected to the mounting frame. A rectangular through hole is provided on the side of the valve body at one end away from the mounting frame. The valve body is provided with a water inlet and a water outlet. The regulating unit is fixedly connected to the valve body. The regulating unit has the function of regulating water flow. The regulating unit is slidably connected to the protective unit. The protective unit is fixedly installed inside the valve body. The protective unit has the function of protecting the valve body from impact.

[0009] The mounting frame is used to install and fix the valve body, and the valve body is used to install and fix the regulating unit and the protective unit. The regulating unit is used for adaptive flow adjustment, and the protective unit is used to protect the inside of the valve body from instantaneous impact of the water flow. When the water flows into the valve body, the regulating unit is started by controlling the size of the water pressure, thereby controlling the adjustment of the water flow rate to achieve the function of self-regulation of the water flow rate. When a water flow with a strong impact force enters the inside of the valve body, the protective unit will be started with the cooperation of the regulating unit, thereby weakening the high impact force brought by the strong water flow through the protective unit, avoiding the water flow with a strong impact force from damaging the inside of the valve body and affecting the service life.

[0010] Furthermore, the regulating unit includes a water push plate, an inner gear ring, a driving gear, a telescopic rotating rod, a fixed plate, a rack, an electromagnet, a magnetic block, an installation box, a push rod, a push switch, a driven gear, a rotating rod, a valve disc and a buffer spring. The water push plate is rotatably installed inside the valve body, the water push plate is fixedly connected to the inner gear ring, a large annular groove and a small annular groove are provided at one end of the water push plate close to the inner gear ring, the small annular groove of the water push plate is slidably connected to the driving gear through a straight rod, the driving gear is fixedly connected to the straight rod, and the water push plate The large annular groove is slidably connected to the driven gear through a straight rod, the driven gear is fixedly connected to the straight rod, the inner gear ring is meshed with the driving gear, the driving gear is fixedly connected to the movable part of the telescopic rotating rod, the fixed part of the telescopic rotating rod is fixedly connected to the fixed plate, the telescopic rotating rod is a movable part with one end close to the rack, the movable part of the telescopic rotating rod is provided with a thread meshing with the tooth shape of the rack, one end of the rack is meshed with the telescopic rotating rod in the vertical direction, and the other end is slidably connected with the magnetic block, the electromagnet is fixed The invention is installed on the inner surface of an end of the installation box away from the horizontal foundation, the magnetic block is slidably installed inside the installation box, the magnetic block is fixedly installed on the lower surface of an end of the push rod close to the horizontal foundation, the installation box is fixedly installed in a rectangular through hole opened in the valve body, the push rod is slidably connected to the installation box, the push rod is slidably connected to the electromagnet, there are two push switches, both of which are fixedly installed on the inner wall of the installation box, the push switches are electrically connected to the electromagnet, the driven gear is meshed with the driving gear, the rotating rod is composed of a fixed end and a telescopic end, the driven gear is fixedly connected to the movable end of the rotating rod, both ends of the rotating rod are fixedly connected to the valve disc, the valve disc close to one end of the rack is rotatably installed at the water inlet opened in the valve body, and the valve disc away from one end of the rack is fixedly installed at the water outlet opened in the valve body, one end of the buffer spring is fixedly connected to the inner gear ring, and the other end is fixedly connected to the protrusion inside the valve body, a circular through hole is opened on the inner gear ring, a conductive ring is arranged in the circular through hole, and the conductive ring on the inner gear ring is slidably connected to the protection unit.

[0011] When the external water pressure is too large, when the water flows through the valve disc and enters the inside of the valve body, the pressure of the water flow impacts the water push plate, driving the inner gear ring, the active gear and the driven gear to move to the right synchronously to squeeze the buffer spring for buffering. At the same time, the active gear drives the telescopic rotating rod to contract to the right, thereby driving the rack to slide to the right in the magnetic block under the action of the thread of the telescopic rotating rod to squeeze the push switch on the right. At this time, the push switch conducts the positive current circuit, and transmits the current in the external controller to the electromagnet, so that the electromagnet and the magnetic block have the same polarity, thereby pushing the magnetic block to drive the rack to move downward synchronously. During the downward movement of the rack, it cooperates with the thread to drive the telescopic rotating rod to rotate in the fixed plate 35, so that the active gear drives the driven gear to rotate, drives the rotating rod to rotate, and causes the valve disc at the water inlet to rotate, and does not overlap with the valve disc at the water outlet, gradually reducing the overlapping area of ​​the valve disc, so that the water entering the valve The water flow inside the valve body is reduced, thereby preventing the valve body from being damaged by excessive internal pressure caused by water flow. When the water flow pressure becomes smaller, the inner gear ring, the driving gear and the driven gear are driven to move to the left under the action of the buffer spring. When the driving gear moves to the left, it drives the rack to squeeze the left push switch to the left and releases the right push switch at the same time. At this time, the circuit conducts a reverse current circuit, so that the electromagnet and the magnetic block are of opposite polarity to attract the magnetic block to move upward, driving the rack to move upward, thereby driving the telescopic rotating rod to rotate in the opposite direction, causing the driving gear to rotate in the opposite direction, and under the transmission action of the driven gear, the valve disc at the water inlet of the valve body is driven to rotate in the opposite direction, and completely overlap with the valve disc at the water outlet, thereby maximizing the flow area and increasing the water flow to meet the user's needs. The push rod is to ensure the normal operation of the valve body by manually pushing and pulling the push rod when the internal push switch fails.

[0012] Furthermore, the protection unit includes a coil, a ceramic rod, an arc-shaped bend pipe and a baffle. A circular groove is provided at the inner protrusion of the valve body. One end of the ceramic rod is slidably connected to the circular groove protruding inside the valve body, and the other end is slidably connected to the inner gear ring. The coil is evenly wound on the outer surface of the ceramic rod. The conductive ring on the inner gear ring is electrically connected to the memory spring in the arc-shaped bend pipe. A memory spring is arranged in the arc-shaped bend pipe. One end of the arc-shaped bend pipe is fixedly connected to the inside near the water outlet of the valve body, and the other end is fixedly connected to the baffle. The baffle is rotatably connected to the valve body through a rotating shaft.

[0013] When the water flow pressure exceeds the bearing capacity of the valve body, the long-term water flow impact causes the valve body to be damaged. At this time, the water flow pressure pushes the inner gear ring to move to the right. At this time, the effective number of circles of contact between the coil on the ceramic rod and the conductive ring on the inner gear ring gradually decreases, and the resistance gradually decreases, thereby gradually increasing the current delivered to the memory spring in the arc elbow. When receiving a large current, the memory spring heats up, expands and elongates in the arc elbow, pushing the baffles closer to each other, removing most of the strong water flow impact force while cooperating with the valve disc to reduce the pressure of water entering the valve body, thereby protecting the inside of the valve body from impact, increasing the service life and enabling the regulating valve to work normally, thereby ensuring normal working requirements.

[0014] Furthermore, the two valve flaps overlap initially.

[0015] The initial overlap of the valve disc is to provide the maximum flow area for water to flow through while detecting the water flow pressure, thereby adaptively adjusting the flow rate of water entering the valve body according to the water flow pressure.

[0016] Furthermore, when the magnetic block moves downwardly at a maximum distance in the installation box, the overlap area of ​​the two valve flaps is 1 / 5.

[0017] In order to ensure that the valve body can work normally and avoid the impact of high-pressure water flow on the inside of the valve body, which may cause damage and affect its service life.

[0018] Furthermore, there are two baffles, and the rotation angle of the two baffles is 0-60°. When the two baffles are rotated to 60°, the water flow rate is 1 / 10 of that when the two baffles are rotated to 0°.

[0019] The two baffles can be rotated between 0°-60° as needed. By adjusting different combinations of rotation angles, the flow direction and impact direction of the water flow can be changed. When the baffle rotates at a small angle, the water flow mainly impacts along the original direction, but after being blocked and guided by the baffle, part of the water flow will change direction, dispersing the concentrated impact on the regulating valve. When the baffle is rotated to a larger angle such as 60°, the water flow direction is changed to a greater extent, and the impact force is dispersed in different directions, avoiding the impact force from being concentrated on a certain part of the regulating valve, making the overall force of the regulating valve more uniform, and further reducing the risk of damage due to excessive local force. When the baffle is rotated to 60°, the water flow rate is greatly reduced to 1 / 10 of that at 0°, and the speed and kinetic energy of the water flow are also greatly reduced accordingly, further protecting the valve body and being able to accurately control the delivery volume of high-pressure water flow according to actual needs.

[0020] Furthermore, one end of the coil close to the water outlet of the valve body is a current output end.

[0021] In order to provide a larger current for the memory spring in the arc elbow by reducing the effective number of turns of the coil when the valve body encounters high-pressure water flow, the baffles are pushed closer to each other, which reduces the water flow while removing most of the impact force of the water flow, thereby protecting the valve body and increasing its service life.

[0022] Furthermore, the coil is electrically connected to an external controller.

[0023] In order to realize the automation of the device and adaptively adjust the water flow according to the water pressure, the water flow can be precisely regulated while meeting the user's needs.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When the water flow pressure is too large, the present invention drives the telescopic rotating rod to retract to the right through the active gear in the regulating unit, thereby driving the rack to slide to the right on the magnetic block to squeeze the push switch on the right, so that the electromagnet is energized with the same polarity as the magnetic block, pushing the magnetic block to drive the rack to move downward synchronously, and driving the telescopic rotating rod to rotate under the cooperation of the thread, thereby driving the rotating rod and the valve disc to rotate under the transmission action of the active gear and the driven gear, gradually reducing the overlapping area of ​​the valve disc, reducing the water flow entering the valve body, thereby avoiding damage to the valve body caused by excessive internal pressure due to water flow. When the pressure becomes smaller, the inner gear ring, the driving gear and the driven gear are driven to move to the left under the action of the buffer spring. When the driving gear moves to the left, it drives the rack to squeeze the left push switch to the left and releases the right push switch at the same time. At this time, the circuit conducts the reverse current circuit, so that the electromagnet attracts the magnetic block to move upward, and the telescopic rotating rod is rotated in the opposite direction under the action of the rack. Under the transmission action of the driving gear and the driven gear, the valve disc at the water inlet of the valve body is driven to rotate in the opposite direction and completely overlap with the valve disc at the water outlet, thereby maximizing the flow area and increasing the water flow to meet the user's needs.

[0026] 2. The present invention gradually reduces the effective number of turns of the coil on the ceramic rod in the protection unit, increases the current of the memory spring in the arc-shaped elbow, causes it to heat up, expand and elongate, pushes the baffles closer to each other, removes most of the strong water flow impact force, and cooperates with the valve disc to reduce the water flow rate to protect the internal structure of the valve body, thereby increasing the service life and allowing the regulating valve to work normally, thereby ensuring normal working requirements.

[0027] 3. The push rod in the present invention is designed to ensure the normal operation of the valve body by manually pushing and pulling the push rod when the internal push switch fails. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The mounting frame 1 is used for mounting and fixing the valve body 2, and the valve body 2 is used for mounting and fixing the regulating unit 3 and the protective unit 4. The regulating unit 3 is used for adaptively adjusting the flow rate, and the protective unit 4 is used for protecting the inside of the valve body 2 from instantaneous impact of the water flow. When the water flow enters the valve body 2, the regulating unit 3 is started by controlling the size of the water pressure, thereby controlling the adjustment of the water flow rate to achieve the function of self-regulation of the water flow rate. When a water flow with a strong impact force enters the inside of the valve body 2, the protective unit 4 will be started with the cooperation of the regulating unit 3, thereby weakening the high impact force brought by the strong water flow through the protective unit 4, thereby avoiding the water flow with a strong impact force from damaging the inside of the valve body 2 and affecting the service life.

[0042] like Figure 2 , 3As shown in Figures 4, 5, 6 and 7, the regulating unit 3 includes a water push plate 31, an inner gear ring 32, a driving gear 33, a telescopic rotating rod 34, a fixed plate 35, a rack 36, an electromagnet 37, a magnetic block 38, a mounting box 39, a push rod 310, a push switch 311, a driven gear 312, a rotating rod 313, a valve flap 314 and a buffer spring 315. The water push plate 31 is rotatably installed inside the valve body 2. The water push plate 31 is fixedly connected to the inner gear ring 32. A large annular groove and a small annular groove are provided at one end of the water push plate 31 close to the inner gear ring 32. The small annular groove of the water push plate 31 is slidably connected to the driving gear 33 through a straight rod. The driving gear 33 is fixedly connected to the straight rod, the large annular groove of the water push plate 31 is slidably connected to the driven gear 312 through the straight rod, the driven gear 312 is fixedly connected to the straight rod, the inner gear ring 32 is meshed with the driving gear 33, the driving gear 33 is fixedly connected to the movable part of the telescopic rotating rod 34, the fixed part of the telescopic rotating rod 34 is fixedly connected to the fixed plate 35, the telescopic rotating rod 34 is a movable part with one end close to the rack 36, the movable part of the telescopic rotating rod 34 is provided with a thread meshing with the tooth shape of the rack 36, one end of the rack 36 is meshed with the telescopic rotating rod 34 in the vertical direction, and the other end slides with the magnetic block 38 The electromagnet 37 is fixedly mounted on the inner surface of the mounting box 39 away from the horizontal foundation, the magnetic block 38 is slidably mounted inside the mounting box 39, the magnetic block 38 is fixedly mounted on the lower surface of the push rod 310 close to the horizontal foundation, the mounting box 39 is fixedly mounted in the rectangular through hole of the valve body 2, the push rod 310 is slidably connected to the mounting box 39, the push rod 310 is slidably connected to the electromagnet 37, there are two push switches 311, both of which are fixedly mounted on the inner wall of the mounting box 39, the push switches 311 are electrically connected to the electromagnet 37, the driven gear 312 is meshed with the driving gear 33, The rotating rod 313 consists of a fixed end and a telescopic end. The driven gear 312 is fixedly connected to the movable end of the rotating rod 313. Both ends of the rotating rod 313 are fixedly connected to the valve flap 314. The valve flap 314 close to one end of the rack 36 is rotatably installed at the water inlet opened in the valve body 2, and the valve flap 314 away from one end of the rack 36 is fixedly installed at the water outlet opened in the valve body 2. One end of the buffer spring 315 is fixedly connected to the inner gear ring 32, and the other end is fixedly connected to the internal protrusion of the valve body 2. A circular through hole is opened on the inner gear ring 32, and a conductive ring is arranged in the circular through hole. The conductive ring on the inner gear ring 32 is slidably connected to the protective unit 4.

[0043] When the external water pressure is too large, the water flows through the valve disc 314 and enters the valve body 2. The water pressure impacts the water push plate 31, driving the inner gear ring 32, the driving gear 33 and the driven gear 312 to move to the right synchronously to squeeze the buffer spring 315 for buffering. At the same time, the driving gear 33 drives the telescopic rotating rod 34 to retract to the right, thereby driving the rack 36 to slide to the right in the magnetic block 38 under the action of the thread of the telescopic rotating rod 34 to squeeze the push switch 311 on the right. At this time, the push switch 311 conducts the positive current. The current in the external controller is transmitted to the electromagnet 37, so that the electromagnet 37 and the magnetic block 38 have the same polarity, thereby pushing the magnetic block 38 to drive the rack 36 to move downward synchronously. During the downward movement of the rack 36, it cooperates with the thread to drive the telescopic rotating rod 34 to rotate in the fixed plate 35, so that the driving gear 33 drives the driven gear 312 to rotate, and drives the rotating rod 313 to rotate, so that the valve flap 314 at the water inlet rotates, and does not overlap with the valve flap 314 at the water outlet, and gradually reduces the overlapping area of ​​the valve flap 314. , so that the water flow entering the valve body 2 is reduced, thereby preventing the valve body 2 from being damaged by excessive internal pressure caused by the water flow. When the water flow pressure becomes smaller, the inner gear ring 32, the driving gear 33 and the driven gear 312 are driven to move to the left under the action of the buffer spring 315. When the driving gear 33 moves to the left, it drives the rack 36 to press the left push switch 311 to the left and release the right push switch 311 at the same time. At this time, the circuit conducts the reverse current circuit, so that the electromagnet 37 and the magnetic block 38 have opposite polarities to attract the magnetic block 311. 8 moves upward, driving the rack 36 to move upward, thereby driving the telescopic rotating rod 34 to rotate in the opposite direction, causing the driving gear 33 to rotate in the opposite direction, and under the transmission action of the driven gear 312, the valve flap 314 at the water inlet of the valve body 2 rotates in the opposite direction, and completely overlaps with the valve flap 314 at the water outlet, thereby maximizing the flow area and increasing the water flow to meet the user's use needs. The push rod 310 is designed to ensure the normal operation of the valve body 2 by manually pushing and pulling the push rod 310 when the internal push switch 311 fails.

[0044] like Figure 6 , 8 As shown in Figures 9, the protection unit 4 includes a coil 41, a ceramic rod 42, an arc-shaped bend pipe 43 and a baffle 44. A circular groove is provided at the protrusion inside the valve body 2. One end of the ceramic rod 42 is slidably connected to the circular groove protruding inside the valve body 2, and the other end is slidably connected to the inner gear ring 32. The coil 41 is evenly wound on the outer surface of the ceramic rod 42. The conductive ring on the inner gear ring 32 is electrically connected to the memory spring in the arc-shaped bend pipe 43. A memory spring is arranged in the arc-shaped bend pipe 43. One end of the arc-shaped bend pipe 43 is fixedly connected to the inside near the water outlet of the valve body 2, and the other end is fixedly connected to the baffle 44. The baffle 44 is rotatably connected to the valve body 2 through a rotating shaft.

[0045] When the water flow pressure exceeds the bearing capacity of the valve body 2, the valve body 2 is damaged due to the long-term water flow impact. At this time, when the water flow pressure pushes the inner gear ring 32 to move to the right, the effective number of circles of contact between the coil 41 on the ceramic rod 42 and the conductive ring on the inner gear ring 32 gradually decreases, and the resistance gradually decreases, thereby gradually increasing the current delivered to the memory spring in the arc-shaped elbow 43. When receiving a large current, the memory spring heats up, expands and elongates in the arc-shaped elbow 43, pushing the baffle 44 closer to each other, removing most of the strong water flow impact force while cooperating with the valve flap 314 to reduce the pressure of water entering the valve body 2, thereby protecting the inside of the valve body 2 from impact, increasing the service life and enabling the regulating valve to work normally, thereby ensuring normal working requirements.

[0046] like Figure 2 As shown, the two valve flaps 314 initially overlap.

[0047] The initial overlap of the valve flap 314 is to provide the maximum flow area for water flow while detecting the water flow pressure, thereby adaptively adjusting the flow rate of water entering the valve body 2 according to the water flow pressure.

[0048] like Figure 7 As shown, when the maximum downward movement distance of the magnetic block 38 in the installation box 39 is 1 / 5, the two valve flaps 314 completely overlap.

[0049] In order to ensure that the valve body 2 can work normally and avoid the impact of high-pressure water flow on the inside of the valve body 2 to cause damage and shorten its service life.

[0050] like Figure 6 As shown, there are two baffles 44, and the rotation angle of the two baffles 44 is 0-60 degrees. When the two baffles 44 rotate to 60 degrees, the water flow rate is 1 / 10 of that when the two baffles 44 rotate to 0 degrees.

[0051] The two baffles 44 can be rotated between 0°-60° as needed. By adjusting different combinations of rotation angles, the flow direction and impact direction of the water flow can be changed. When the baffle 44 rotates at a small angle, the water flow mainly impacts along the original direction, but after being blocked and guided by the baffle 44, part of the water flow will change direction, dispersing the concentrated impact on the regulating valve. When the baffle 44 is rotated to a larger angle such as 60°, the water flow direction is changed to a greater extent, and the impact force is dispersed in different directions, avoiding the impact force from being concentrated on a certain part of the regulating valve, making the overall force on the regulating valve more uniform, and further reducing the risk of damage due to excessive local force. When the baffle 44 is rotated to 60°, the water flow rate is greatly reduced to 1 / 10 of that at 0°, and the speed and kinetic energy of the water flow are also greatly reduced accordingly, further protecting the valve body 2 while being able to accurately control the delivery volume of high-pressure water flow according to actual needs.

[0052] like Fig. 9As shown, the end of the coil 41 close to the water outlet of the valve body 2 is the current output end.

[0053] In order to provide a larger current for the memory spring in the arc elbow 43 by reducing the effective number of turns of the coil 41 when the valve body 2 encounters a high-pressure water flow, the baffle plates 44 are pushed closer to each other, thereby reducing the water flow rate and removing most of the impact force of the water flow, thereby protecting the valve body 2 and increasing its service life.

[0054] like Fig. 9 As shown, the coil 41 is electrically connected to the external controller.

[0055] In order to realize the automation of the device and adaptively adjust the water flow according to the water pressure, the water flow can be precisely regulated while meeting the user's needs.

[0056] Working principle of the present invention:

[0057] When the external water pressure is too large, when the water flows through the valve disc 314 and enters the valve body 2, the pressure of the water flow impacts the water push plate 31, driving the inner gear ring 32, the driving gear 33 and the driven gear 312 to move to the right synchronously to squeeze the buffer spring 315 for buffering. At the same time, the driving gear 33 drives the telescopic rotating rod 34 to shrink to the right, thereby driving the rack 36 to slide to the right in the magnetic block 38 under the action of the thread of the telescopic rotating rod 34 to squeeze the right push switch 311. At this time, the push switch 311 conducts the positive current circuit, and transmits the current in the external controller to the electromagnet 37, so that the electromagnet 37 and the magnetic block 38 have the same polarity, thereby pushing the magnetic block 38 to drive the rack 36 to move downward synchronously. During the downward movement of the rack 36, it cooperates with the thread to drive the telescopic rotating rod 34 to rotate in the fixed plate 35, so that the driving gear 33 drives the driven gear 312 to rotate, and drives the rotating rod 313 to rotate, so that the valve disc 314 at the water inlet rotates. The valve flap 314 at the water outlet does not overlap, and the overlapping area of ​​the valve flap 314 is gradually reduced, so that the water flow entering the valve body 2 is reduced, thereby preventing the valve body 2 from being damaged by excessive internal pressure caused by the water flow. When the water flow pressure exceeds the bearing capacity of the valve body 2, the valve body 2 is damaged due to long-term water flow impact. At this time, when the water flow pressure pushes the inner gear ring 32 to move to the right, the effective number of circles of contact between the coil 41 on the ceramic rod 42 and the conductive ring on the inner gear ring 32 gradually decreases, and the resistance gradually decreases, thereby gradually increasing the current delivered to the memory spring in the arc elbow 43. When receiving a large current, the memory spring heats up, expands and stretches in the arc elbow 43, pushing the baffle 44 closer to each other, removing most of the strong water flow impact force while cooperating with the valve flap 314 to reduce the pressure of water entering the valve body 2, thereby protecting the inside of the valve body 2 from impact, increasing the service life, and allowing the regulating valve to work normally, thereby ensuring normal working requirements.

[0058] When the water flow pressure becomes smaller, the inner gear ring 32, the driving gear 33 and the driven gear 312 are driven to move to the left under the action of the buffer spring 315. When the driving gear 33 moves to the left, it drives the rack 36 to squeeze the left push switch 311 to the left and release the right push switch 311 at the same time. At this time, the circuit conducts a reverse current circuit, so that the electromagnet 37 and the magnetic block 38 are of opposite polarity to attract the magnetic block 38 to move upward, driving the rack 36 to move upward, thereby driving the telescopic rotating rod 34 to rotate in the opposite direction, causing the driving gear 33 to rotate in the opposite direction, and under the transmission action of the driven gear 312, the valve disc 314 at the water inlet of the valve body 2 is driven to rotate in the opposite direction, and completely overlap with the valve disc 314 at the water outlet, thereby maximizing the flow area and increasing the water flow to meet the user's needs. The push rod 310 is to ensure that when the internal push switch 311 fails, the push rod 310 can be manually pushed and pulled to ensure the normal operation of the valve body 2.
