Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flow valve, in particular to an energy-saving flow regulating valve. BACKGROUND

[0002] Flow regulating valve is a device used to control the flow, pressure or direction of fluid (such as water, gas, steam, etc.), widely used in industrial piping systems, heating, ventilation and air conditioning, water conservancy engineering and energy management fields. Its core function is to change the flow area by adjusting the opening of the valve, so as to realize the accurate control of fluid flow. Traditional flow regulating valve can be divided into manual regulating valve, pneumatic regulating valve and electric regulating valve according to the control principle. Among them, electric regulating valve gradually becomes the mainstream because of its high degree of automation and fast response. However, with the increasing requirements of industrial systems on energy saving, reliability and maintenance cost, the limitations of traditional flow regulating valve gradually appear, and structural optimization and technological innovation are urgently needed.

[0003] The flow regulating valve on the current market relies on electric actuator (such as servo motor, stepper motor, etc.) to drive the movement of valve core, which has the following defects:

[0004] Firstly, the structure of electric regulating valve is complex and the cost is high: electric regulating valve needs to integrate motor, controller, sensor and other components, which leads to bulky overall structure and greatly increases the manufacturing cost. In addition, the introduction of electrical components also increases the failure rate, especially in humid, high temperature or corrosive environment, the motor is easy to be damaged, which affects the service life of the valve.

[0005] Secondly, the energy consumption of electric regulating valve is high and the maintenance is difficult: electric valve needs continuous power supply to maintain the working state, and the long-term operation energy consumption is large. The internal structure of electric valve is complex, and the troubleshooting and component replacement need to be operated by professional personnel, which has high maintenance cost.

[0006] Moreover, the response of electric regulating valve is lagging: the mechanical transmission chain of electric actuator is long, which is easy to cause response delay due to gear clearance or inertia, and it is difficult to realize rapid and accurate regulation of flow. For example, in the scene of frequent pressure fluctuation of pipe network, electric valve may cause system pressure imbalance due to regulation lag, and even cause safety hazards. SUMMARY

[0007] In view of the defects of the prior art, the present application provides an energy-saving flow regulating valve, which overcomes the defects of the prior art and effectively solves the problems of complex structure, high cost, high energy consumption, difficult maintenance and slow response.

[0008] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0009] The utility model provides an energy -conserving flow regulating valve, including the valve body, the valve body includes the valve body, the water inlet welded on the one side outer wall of valve body, the drain welded on the other side outer wall of valve body, the butt joint sleeve welded on the bottom outer wall of valve body, the base welded on the bottom outer wall of butt joint sleeve, the top sleeve welded on the top outer wall of valve body, fixed connection has the shunt pipe between the water inlet and base, and the base is internally provided with the diaphragm, the outer wall center of diaphragm top portion is bonded with the connecting column, and the connecting column top outer wall is welded with the lifting plate, the outer wall of lifting plate is connected with the rotating sleeve slidingly, the outer wall of lifting plate is fixedly connected with the guide ball, and the outer wall of rotating sleeve is provided with the spiral groove, the guide ball is connected on the inner wall of spiral groove slidingly, the top outer wall of rotating sleeve is welded with lower rotary shaft, and the top outer wall of lower rotary shaft is welded with the ball valve.

[0010] Through the above-mentioned scheme, the valve body is used as the core pressure-bearing component, the water inlet, the drain, the butt joint sleeve and the top sleeve are connected by welding. The shunt pipe is fixed between the water inlet and the base to form a water pressure transmission channel. The water pressure control cavity in the base is embedded with the diaphragm through the clamping groove. The diaphragm top is rigidly connected with the lifting plate through the connecting column. In the flow regulating cavity, the guide ball of the lifting plate cooperates with the spiral groove of the rotating sleeve to convert the vertical displacement of the diaphragm into the circumferential movement of the rotating sleeve. The welding connection between the lower rotary shaft and the ball valve ensures the effective transmission of the rotary torque, realizing the continuous adjustment of the valve opening. When the pressure of the water inlet increases, the water pressure is transmitted to the water pressure control cavity through the shunt pipe, pushing the diaphragm to move upward, driving the lifting plate and the guide ball to slide along the spiral groove, forcing the rotating sleeve to rotate. The ball valve rotates with the lower rotary shaft, increasing the valve opening to increase the flow; on the contrary, when the pressure decreases, the diaphragm moves downward, the ball valve closes, realizing the self-adaptive adjustment of the flow.

[0011] The traditional electric actuator is abandoned, and the flow is adjusted by the water pressure driving diaphragm and mechanical linkage device. The spiral groove cooperation design of the lifting plate and the rotating sleeve can convert the vertical movement of the diaphragm into the rotary action of the ball valve, without external power input, greatly simplifying the structure and reducing the failure risk. Using the fluid pressure as the driving force, without additional energy supply, significantly reducing the operating energy consumption. At the same time, the diaphragm and the shunt pipe can respond to the water pressure change in real time, ensuring the immediacy and accuracy of the flow regulation, adapting to the dynamic working condition requirements.

In addition, the minimum flow limiting hole and the maximum flow limiting hole on the T-shaped plate are limited by the lead screw, which can preset the minimum and maximum range of the flow, avoid frequent manual adjustment, and further reduce maintenance cost. The sealing bearing and the first sealing ring are installed in the first sealing groove and the second sealing groove to ensure the sealing performance of the lower rotating shaft and the upper rotating shaft during rotation. The second sealing ring at the bottom of the base tightly fits with the shunt pipe to prevent leakage of the water pressure control cavity.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0040] Reference Figures 1-10 , embodiment one, an energy-saving flow regulating valve, comprising a valve body 1, the valve body 1 comprising a valve body 101, a water inlet 102 welded to one side of the outer wall of the valve body 101, a drain port 103 welded to the other side of the outer wall of the valve body 101, an interface sleeve 104 welded to the bottom outer wall of the valve body 101, a base 105 welded to the bottom outer wall of the interface sleeve 104, and a top sleeve 106 welded to the top outer wall of the valve body 101.

[0041] In this embodiment, the valve body 101 as the core pressure-bearing component is connected by welding with the water inlet 102, the drain port 103, the butt joint sleeve 104 and the top sleeve 106. The shunt pipe 2 is fixed between the water inlet 102 and the base 105 to form a water pressure transmission channel. The water pressure control cavity 20 in the base 105 is embedded with the diaphragm 3 through the clamping groove 21, and the diaphragm 3 is rigidly connected with the lifting plate 5 through the connecting column 4 at the top.

[0042] In this embodiment, the water inlet 102 and the base 105 are fixedly connected with the shunt pipe 2, and the diaphragm 3 is arranged in the base 105. The connecting column 4 is bonded to the outer wall center at the top of the diaphragm 3, the lifting plate 5 is welded to the outer wall at the top of the connecting column 4, the rotating sleeve 6 is slidingly connected to the outer wall of the lifting plate 5, the guide ball 7 is fixedly connected to the outer wall of the lifting plate 5, the helical groove 8 is formed in the outer wall of the rotating sleeve 6, the guide ball 7 is slidingly connected to the inner wall of the helical groove 8, the lower rotary shaft 9 is welded to the outer wall at the top of the rotating sleeve 6, and the ball valve 10 is slidingly connected to the inner wall of the valve body 101.

[0043] In this embodiment, the guide ball 7 of the lifting plate 5 and the helical groove 8 of the rotating sleeve 6 cooperate in the flow regulating cavity 19 to convert the vertical displacement of the diaphragm 3 into the circumferential movement of the rotating sleeve 6. The welding connection of the lower rotary shaft 9 and the ball valve 10 ensures the effective transmission of the rotary torque to realize the continuous adjustment of the valve opening. When the pressure of the water inlet 102 rises, the water pressure is transmitted to the water pressure control cavity 20 through the shunt pipe 2 to push the diaphragm 3 to move upward, drive the lifting plate 5 and the guide ball 7 to slide along the helical groove 8, and force the rotating sleeve 6 to rotate. The ball valve 10 rotates with the lower rotary shaft 9 to increase the valve opening to increase the flow; on the contrary, when the pressure decreases, the diaphragm 3 moves downward, the ball valve 10 closes, and the flow is self-adaptively adjusted.

[0044] The traditional electric actuator is abandoned, and the flow is adjusted by the water pressure to drive the diaphragm 3 and the mechanical linkage device. The lifting plate 5 and the helical groove 8 of the rotating sleeve 6 are cooperatively designed to convert the vertical movement of the diaphragm 3 into the rotary action of the ball valve 10, without the need for external power input, which greatly simplifies the structure and reduces the failure risk. The fluid pressure is used as the driving force, without the need for additional energy supply, which significantly reduces the operating energy consumption. At the same time, the diaphragm 3 and the shunt pipe 2 can respond to the water pressure change in real time to ensure the instantness and accuracy of the flow adjustment, and adapt to the dynamic working condition requirements.

[0045] In the third embodiment, the upper rotary shaft 11 is welded at the center of the outer wall of the top of the ball valve 10, and the cross positioning pin 12 is welded at the top of the outer wall of the upper rotary shaft 11. The connecting plate 14 is slidably connected to the outer wall of the cross positioning pin 12. The screw rod 15 is screwed to the inner wall of the connecting plate 14. The cross positioning groove 18 is formed in the outer wall of one end of the connecting plate 14 away from the screw rod 15. The cross positioning pin 12 is slidably connected to the inner wall of the cross positioning groove 18. The T-shaped plate 13 is welded to the outer wall of the top sleeve 106. The minimum flow limiting hole 16 is formed in one side of the top outer wall of the T-shaped plate 13. The maximum flow limiting hole 17 is formed in one side of the top outer wall of the T-shaped plate 13. The screw rod 15 is located at the top of the T-shaped plate 13. The outer diameter of the screw rod 15 is adapted to the inner diameter of the minimum flow limiting hole 16 and the maximum flow limiting hole 17.

[0046] In the third embodiment, the T-shaped plate 13 limits the rotation angle of the ball valve 10 by cooperating with the screw rod 15 and the cross positioning pin 12. The hole diameters of the minimum flow limiting hole 16 and the maximum flow limiting hole 17 are adapted to the outer diameter of the screw rod 15. The flow threshold value is preset by adjusting the position of the screw rod 15 to avoid over-limit operation.

[0047] The combination of the sealing bearing 24 and the double sealing ring (the first sealing ring 25 and the second sealing ring 26) effectively prevents leakage and prolongs the service life of the valve. In addition, the minimum flow limiting hole 16 and the maximum flow limiting hole 17 on the T-shaped plate 13 are limited by the screw rod 15 to preset the minimum and maximum ranges of the flow, avoiding frequent manual adjustment and further reducing maintenance costs.

[0048] The flow adjusting cavity 19 is arranged in the interior of the butt joint sleeve 104, and the lifting plate 5 and the rotating sleeve 6 are arranged in the interior of the flow adjusting cavity 19. The water pressure control cavity 20 is arranged in the interior of the base 105, and the clamping groove 21 is formed in the inner wall of the water pressure control cavity 20. The diaphragm 3 is embedded in the inner wall of the clamping groove 21, and the shunt pipe 2 is communicated to the inner wall of the water pressure control cavity 20. The first sealing groove 22 is formed in the inner wall of the butt joint sleeve 104, and the second sealing groove 23 is formed in the inner wall of the top sleeve 106. The sealing bearing 24 is arranged in the inner wall of the first sealing groove 22 and the second sealing groove 23. The first sealing ring 25 is arranged on the upper surface and the lower surface of the sealing bearing 24. The second sealing ring 26 is embedded in the inner wall of the bottom of the base 105 and tightly attached to the outer wall of one end of the shunt pipe 2. The lower rotary shaft 9 penetrates between the valve body 101 and the butt joint sleeve 104, and is rotatably connected to the inner wall of the sealing bearing 24 and the first sealing ring 25 in the first sealing groove 22. The upper rotary shaft 11 penetrates between the valve body 101 and the top sleeve 106, and is rotatably connected to the inner wall of the sealing bearing 24 and the first sealing ring 25 in the second sealing groove 23.

[0049] The first sealing groove 22 and the second sealing groove 23 are provided with a sealing bearing 24 and a first sealing ring 25, which ensure the sealing of the lower rotating shaft 9 and the upper rotating shaft 11 during rotation. The second sealing ring 26 at the bottom of the base 105 is tightly attached to the shunt pipe 2, preventing leakage of the water pressure control cavity 20.

[0050] The outer wall of one end of the water inlet 102 is provided with a water inlet pipe 27, and the outer wall of one end of the water outlet 103 is provided with a water outlet pipe 28. Flanges 29 are welded on the outer walls of the water inlet 102, the water inlet pipe 27, the water outlet 103 and the water outlet pipe 28, and fastening bolts 30 are installed between the two flanges 29 on the same side at equal distances. Pressure gauges 31 are installed on the outer walls of both sides of the top of the T-shaped plate 13, and probes are provided on the outer walls of the bottom of the pressure gauges 31, which are fixedly connected to the inner walls of the top of the water inlet 102 and the water outlet 103.

[0051] The probes of the pressure gauges 31 are fixed to the inner walls of the top of the water inlet 102 and the water outlet 103 to monitor the pressure difference between the inlet and outlet in real time, providing data support for flow regulation. The standardized design of the flanges 29 and the fastening bolts 30 simplifies the pipeline docking process, ensuring firm installation and reliable sealing.

[0052] Working principle:

[0053] 1. Initial state: The valve body 1 is in a closed or minimum opening state, the diaphragm 3 is in a balanced position under the action of the pressure in the water pressure control cavity 20, the ball valve 10 is locked by the cross positioning pin 12 and the lead screw 15, and the flow is zero or maintains a preset minimum value.

[0054] 2. Pressure response stage: First, rotate the lead screw 15 to move it away from the minimum flow limiting hole 16 or the maximum flow limiting hole 17. When the pressure of the water inlet 102 increases, the fluid enters the water pressure control cavity 20 through the shunt pipe 2, the diaphragm 3 is lifted by the pressure, and the lifting plate 5 is pushed to move vertically through the connecting column 4. The guide ball 7 slides along the spiral groove 8 of the rotating sleeve 6, converting linear motion into circumferential rotation of the rotating sleeve 6, driving the lower rotating shaft 9 and the ball valve 10 to rotate, gradually opening the valve port of the ball valve 10.

[0055] 3. Flow regulation stage: The opening of the ball valve 10 is positively related to the water inlet pressure, and the flow increases with the increase of the valve port cross-sectional area. The pressure gauges 31 on the T-shaped plate 13 monitor the pressure changes in real time. If the flow approaches the preset maximum value (limited by the maximum flow limiting hole 17), the lead screw 15 abuts against the limiting hole edge, preventing the ball valve 10 from rotating excessively, ensuring system safety.

[0056] 4. Pressure release and reset: When the water inlet pressure decreases, the pressure in the water pressure control cavity 20 weakens, and the diaphragm 3 resets under the action of its own weight, driving the lifting plate 5 to move downward, the guide ball 7 slides reversely to make the rotating sleeve 6 rotate reversely, the ball valve 10 gradually closes, and the flow decreases until the initial state is restored.

[0057] The above process realizes dynamic balance of flow through a pure mechanical structure, does not need external energy input, has high efficiency, reliability and energy saving, and is suitable for long-term stable operation under complex working conditions.

[0058] The above, only for the preferred specific embodiments of the present application, but the scope of protection of the present application is not limited to this, any skilled in the art of the technical personnel in the technical range disclosed by the present application, according to the technical scheme of the present application and the invention concept to equivalent replacement or change, should be covered in the protection scope of the present application.
