Description

Technical Field

[0001] The present invention belongs to the technical field of valves, and in particular relates to a valve with a flow detection function and a use method thereof. Background Art

[0002] Valves are control components in pipeline fluid delivery systems, used to change the cross-section of the passageway and the direction of the medium's flow. Valves are devices that allow or stop the flow of media (liquids, gases, powders) within piping and equipment, and can control their flow. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media, performing functions such as diversion, shutoff, throttling, check, diversion, and overflow pressure relief.

[0003] The globe valve is the most widely used type of valve. Its popularity stems from its low friction between the sealing surfaces during opening and closing, its durability, its low opening height, its ease of manufacture, and its convenient maintenance. It is suitable for both low and medium pressures, as well as high pressures. The closing principle of a globe valve is that the valve stem pressure forces the disc sealing surface to tightly fit the seat sealing surface, preventing the flow of media.

[0004] However, the existing stop valve has a relatively simple function and can only be opened and closed by rotating the valve stem to drive the valve plate to rise and fall. It is relatively rarely used in combination with a check valve. When the liquid circulates, the circulation pressure cannot be flexibly controlled. When an erroneous operation occurs, the water pressure cannot be controlled and regulated to provide protection. Therefore, we propose a valve with a flow detection function and a method of use to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a valve with a flow detection function, which solves the technical problem that the existing valve has a relatively single function and cannot provide protection by controlling and adjusting the water pressure when an erroneous operation occurs.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A valve with a flow detection function, comprising:

[0008] A valve body, wherein the inner ends of the valve body are respectively provided with a water inlet channel and a water outlet channel, and the channels at both ends of the valve body are provided with an integrally formed connecting flange, and the inner portion of the valve body is provided with a water hole for connecting the water inlet channel and the water outlet channel;

[0009] The mounting seat is connected to the top flange of the valve body through connecting bolts. The top of the mounting seat is symmetrically integrally formed with two connecting rods. The top ends of the two connecting rods are integrally formed with nut blocks. The internal threads of the nut blocks are connected with an adjusting screw. The top end of the adjusting screw is fixedly connected with a rotating handle.

[0010] The rotating cylinder is sealed and rotatably connected to the water hole, and the top of the rotating cylinder is rotatably connected to the bottom of the mounting seat. The internal sealing sliding connection of the rotating cylinder is connected to the valve plate, the top of the valve plate is fixedly connected to the valve stem, the top of the valve stem passes through the top of the mounting seat and is connected to the bottom end of the adjusting screw. The side wall of the rotating cylinder is provided with a water outlet for water discharge;

[0011] The instrument flow meter is fixedly installed on the top side of the valve body and is used to detect the water flow in the water outlet channel.

[0012] Optionally, a first sealing ring is fixedly sleeved on the bottom of the outer wall of the rotating cylinder, and the first sealing ring is sealed against the inner wall of the water hole.

[0013] Optionally, a cavity is provided inside the adjusting screw, a slider is slidably connected inside the cavity, the bottom of the slider is rotatably connected to a support rod, the bottom end of the support rod passes through the bottom end of the adjusting screw and is fixedly connected to the top of the valve stem, and the top of the slider is fixedly connected to the top wall of the cavity with the same compression spring.

[0014] Optionally, there are three water outlet holes, including a low-pressure water outlet hole, a medium-pressure water outlet hole and a high-pressure water outlet hole arranged on different surfaces of the rotating cylinder, and the low-pressure water outlet hole is located below the medium-pressure water outlet hole, and the medium-pressure water outlet hole is located below the high-pressure water outlet hole.

[0015] Optionally, the interior of the valve body is fixedly connected to a fixed arc plate located above the water hole, and the inner wall of the fixed arc plate is fixed with an arc sealing ring, the inner wall of the arc sealing ring is sealed to the outer wall of the rotating cylinder, and any two of the three water outlet holes can be located in the arc sealing ring at the same time.

[0016] Optionally, a third sealing ring is provided on the outer wall of the valve plate, and the third sealing ring is sealed against the inner wall of the rotating cylinder.

[0017] Optionally, a toggle ring is provided on the top fixing sleeve of the outer wall of the valve stem.

[0018] Optionally, the valve body is sealed and fixedly connected to a partition, which is sleeved on the top of the outer wall of the rotating cylinder. The outer wall of the rotating cylinder is fixedly sleeved with a second sealing ring that seals and fits with the through hole of the partition.

[0019] Optionally, a limiting ring is fixedly connected to the inner wall of the bottom end of the rotating cylinder.

[0020] A method for using a valve with a flow detection function comprises the following steps:

[0021] S1. First, according to the water pressure output requirement, the valve stem is rotated by turning the ring to change the connection between the low-pressure water outlet, medium-pressure water outlet, and high-pressure water outlet and the corresponding water outlet channel. At this time, the water in the water inlet channel will push the valve plate upward according to its own water pressure, causing the water to flow out through the water outlet channel. When the water pressure in the water inlet channel decreases, the valve plate automatically returns to its original position, realizing the check function;

[0022] S2. When it is necessary to close the valve or change the water pressure of the water outlet, turn the handle to drive the adjusting screw to rotate. The adjusting screw moves downward to squeeze the compression spring, applying a downward pressure to the valve plate, thereby achieving the effect of closing the valve or changing the water pressure of the water outlet.

[0023] The embodiments of the present invention have the following beneficial effects:

[0024] The present invention provides three water outlet holes at different heights and different sides, and can achieve the passage of water flows with different pressures by adjusting the three water outlet holes. At the same time, by adjusting the adjusting screw, not only can the cut-off effect be achieved, but also the different water outlet pressures of the three water outlet holes can be changed through different degrees of adjustment, which makes it more flexible in use and can also provide a certain protection against misoperation.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0036] Example 1

[0037] See also Figure 1-Figure 5As shown, in this embodiment, a valve with a flow detection function is provided, including a valve body 1, a mounting seat 5, a rotating cylinder 7, and an instrument flow meter 29. The two ends of the valve body 1 are respectively provided with a water inlet channel 2 and a water outlet channel 4. The two end channels of the valve body 1 are provided with an integrally formed connecting flange 3. The interior of the valve body 1 is provided with a water through hole 6 for connecting the water inlet channel 2 and the water outlet channel 4; the mounting seat 5 is connected to the top flange of the valve body 1 by a connecting bolt 30. The top of the mounting seat 5 is symmetrically integrally formed with two connecting rods 8. The top of the two connecting rods 8 is integrally formed with a nut block 9. The inside of the nut block 9 An adjusting screw 10 is threadedly connected therethrough, and a rotating handle 11 is fixedly connected to the top of the adjusting screw 10; the rotating cylinder 7 is sealed and rotatably connected in the water hole 6, and the top of the rotating cylinder 7 is rotatably connected to the bottom of the mounting seat 5, and the internal sealing sliding connection of the rotating cylinder 7 is connected to the valve plate 13, and the top of the valve plate 13 is fixedly connected to the valve stem 12, and the top of the valve stem 12 passes through the top of the mounting seat 5 and is connected to the bottom end of the adjusting screw 10, and a water outlet hole for water outlet is opened on the side wall of the rotating cylinder 7; an instrument flow meter 29 is fixedly installed on the top side of the valve body 1 for detecting the water flow in the water outlet channel 4.

[0038] In one aspect of this embodiment, Figure 4 As shown, there are three water outlets, including a low-pressure water outlet 14, a medium-pressure water outlet 15, and a high-pressure water outlet 16, located on different sides of the rotating drum 7. The low-pressure water outlet 14 is located below the medium-pressure water outlet 15, and the medium-pressure water outlet 15 is located below the high-pressure water outlet 16. By having three water outlets at different heights and not located on the same side, the positions of the three water outlets relative to the water outlet channel 4 can be adjusted by rotating the rotating drum 7, and different water outlet holes can be used to control the flow of different water pressures.

[0039] In one aspect of this embodiment, Figure 4 As shown, the interior of the valve body 1 is fixedly connected to a fixed arc plate 17 located above the water hole 6. The inner wall of the fixed arc plate 17 is fixedly provided with an arc-shaped sealing ring 18. The inner wall of the arc-shaped sealing ring 18 is in sealing contact with the outer wall of the rotating cylinder 7, and any two of the three water outlets can be simultaneously located within the arc-shaped sealing ring 18. By sealing any two of the water outlets with the arc-shaped sealing ring 18, one water outlet can be left to achieve water circulation, thereby playing a regulating role.

[0040] In another aspect of this embodiment, Figure 2-Figure 3As shown, a cavity 21 is provided inside the adjusting screw 10, and a slider 22 is slidably connected inside the cavity 21. A support rod 23 is rotatably connected to the bottom of the slider 22. The bottom end of the support rod 23 passes through the bottom end of the adjusting screw 10 and is fixedly connected to the top end of the valve stem 12. A compression spring 24 is fixedly connected between the top of the slider 22 and the top wall of the cavity 21. When the water pressure in the water inlet channel 2 increases, the water pressure can push the valve plate 13 to slide upward, and the valve plate 13 drives the valve stem 12 upward. At the same time, the support rod 23 drives the slider 22 to slide upward and compress the compression spring 24. At this time, the water in the water inlet channel 2 can enter the water outlet channel 4 through the water outlet hole, thereby achieving the effect of automatic water circulation. When the water pressure in the water inlet channel 2 decreases, the elastic force of the compression spring 24 pushes the valve plate 13 to slide downward and reset, thereby achieving a check function.

[0041] In other aspects of this embodiment, Figure 3 As shown, a toggle ring 27 is fixedly sleeved on the top of the outer wall of the valve stem 12. The toggle ring 27 facilitates the rotation of the valve stem 12. By rotating the valve stem 12, the valve plate 13 can be driven to rotate, and then the rotating cylinder 7 is driven to rotate, thereby achieving an adjustment effect on the water outlet.

[0042] In other aspects of this embodiment, Figure 4 As shown, a first sealing ring 19 is fixedly sleeved on the bottom of the outer wall of the rotating drum 7, and the first sealing ring 19 is sealed against the inner wall of the water hole 6. The provision of the first sealing ring 19 can improve the sealing performance of the rotating drum 7 during rotation.

[0043] Example 2

[0044] Improvements based on Example 1: Refer to the attached Figure 4 The outer wall of the valve plate 13 is provided with a third sealing ring 28, which is sealed against the inner wall of the rotating cylinder 7. The provision of the third sealing ring 28 can improve the sealing performance of the sliding of the valve plate 13 and prevent water from flowing into the upper part of the valve plate 13.

[0045] Example 3

[0046] Improvements based on Example 1: Refer to the attached Figure 4 The interior of the valve body 1 is sealed and fixedly connected to a partition 25, which is mounted on the top of the outer wall of the rotating cylinder 7. A second sealing ring 26 is fixedly mounted on the outer wall of the rotating cylinder 7, sealingly engaging with the through hole of the partition 25. The provision of the partition 25 and the second sealing ring 26 not only improves the rotational stability of the rotating cylinder 7 but also prevents water from flowing above the partition 25, further improving the sealing effect of the valve.

[0047] Example 4

[0048] Improvements based on Example 1: Refer to the attached Figure 4 The inner wall of the bottom end of the rotating cylinder 7 is fixedly connected to a limit ring 20. The limit ring 20 can limit the movement of the valve plate 13. When the valve plate 13 is in a blocked state, its bottom contacts the top of the limit ring 20. At this time, the adjusting screw 10 is driven to rotate by rotating the rotating handle 11, and the adjusting screw 10 slides downward on the slider 22. As the adjusting screw 10 moves downward, the compression spring 24 is gradually compressed. At the same time, a downward pressure is applied to the valve plate 13 through the support rod 23 and the valve stem 12. At this time, by pressurizing the valve plate 13, the valve can be manually closed. In addition, the water outlet pressure of different water outlets can be readjusted in conjunction with the rotation of the rotating cylinder 7, thereby improving the flexibility of use.

[0049] A method for using a valve with a flow detection function comprises the following steps:

[0050] S1. First, according to the water pressure output requirement, the valve stem 12 is rotated by turning the dial ring 27 to change the connection between the low-pressure water outlet hole 14, the medium-pressure water outlet hole 15, and the high-pressure water outlet hole 16 and the water outlet channel 4. At this time, the water in the water inlet channel 2 will push the valve plate 13 upward according to its own water pressure, so that the water flows out through the water outlet channel 4. When the water pressure in the water inlet channel 2 decreases, the valve plate 13 automatically returns to its original position, realizing the check function;

[0051] S2. When it is necessary to close the valve or change the water pressure of the water outlet, the rotating handle 11 is turned to drive the adjusting screw 10 to rotate. The adjusting screw 10 moves downward to squeeze the compression spring 24, and exerts a downward pressure on the valve plate 13, thereby achieving the effect of closing the valve or changing the water pressure of the water outlet.

[0052] It should be noted that:

[0053] When the low-pressure water outlet hole 14 is connected to the water outlet channel 4, the water pressure that can pass through it can be any one of low-pressure water flow, medium-pressure water flow and high-pressure water flow;

[0054] When the medium-pressure water outlet hole 15 is connected to the water outlet channel 4, the water pressure that can pass through it can be either medium-pressure water flow or high-pressure water flow;

[0055] When the high-pressure water outlet hole 16 is connected to the water outlet channel 4, the water pressure that can pass through it is only high-pressure water flow, and the low-pressure water flow and the medium-pressure water flow cannot push the valve plate 13 to the high-pressure water outlet hole 16;

[0056] It should also be noted that:

[0057] When the adjusting screw 10 is rotated and moved downward, the valve can be closed or the water pressure of the outlet hole can be adjusted by the distance moved.

[0058] For example, after adjusting the screw 10 to a certain degree, the pressure of the valve plate 13 will increase, and its ability to withstand water pressure will also increase accordingly. At this time, the low-pressure water outlet 14 may pass through one of the medium-pressure water flow or the high-pressure water flow, or may only pass through the high-pressure water flow, thereby playing a role of flexible adjustment.

[0059] It should be noted that, in the description of this specification, descriptions such as "first", "second", etc. are only used to distinguish various features and have no actual order or directional meaning, and this application is not limited to this.
