Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a perforated eccentric water inlet valve with built-in flow rate indication. Background Technology

[0002] The eccentric water connection valve with live drilling is a water connection device used in the construction of water supply mains, mainly for connecting branch pipes to water supply pipelines. By rotating the eccentric connecting valve, the eccentric hole of the connecting valve can be aligned with or offset from the outlet hole, thus enabling live drilling operations.

[0003] Among the existing patent documents, there is a patent with publication number CN2718364Y entitled "Water-filled perforated eccentric water inlet valve". This patent and similar water-filled perforated eccentric water inlet valves generally have a problem: when the connecting pipe is installed on the connecting nozzle of the water-filled perforated eccentric water inlet valve, the water outlet and the eccentric hole are blocked by the connecting pipe and cannot be observed. At this time, the staff cannot accurately grasp the overlap between the water outlet and the eccentric hole, and thus cannot accurately grasp the flow rate of the water outlet. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a water-filled eccentric water inlet valve with built-in flow rate indication. When adjusting the water flow rate, the water-filled eccentric water inlet valve can accurately determine the flow rate of the water outlet by observing the degree of overlap between the flow rate indication blind hole and the flow rate indication through hole, which represents the degree of overlap between the eccentric hole and the water outlet.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A perforated eccentric water inlet valve with built-in flow rate indication includes a valve body and a valve cover detachably installed on top of the valve body. The valve body and the valve cover have a water outlet at the same position, and a connecting nozzle is connected to the water outlet of the valve cover. A sealing eccentric connecting gate is rotatably installed inside the valve body. An eccentric hole of the same size as the water outlet is opened through the eccentric connecting gate. The opening / closing of the water outlet and the flow rate of the water outlet can be controlled by rotating the eccentric connecting gate.

[0007] The valve cover has a flow indication through hole of the same size as the eccentric hole, and the upper surface of the eccentric connecting column door has a flow indication blind hole of the same size as the eccentric hole.

[0008] When the eccentric hole and the outlet hole are aligned in the same direction, the flow indicator blind hole and the flow indicator through hole are also aligned in the same direction. If the eccentric connecting column door is rotated, the overlap between the flow indicator blind hole and the flow indicator through hole is exactly the same as the overlap between the eccentric hole and the outlet hole.

[0009] Using the above scheme, when adjusting the water flow rate, the eccentric water inlet valve with water-filled perforation can accurately determine the flow rate of the outlet by observing the degree of overlap between the flow rate indicator blind hole and the flow rate indicator through hole, which represents the degree of overlap between the eccentric hole and the outlet hole.

[0010] In a preferred embodiment of a perforated eccentric water inlet valve with built-in flow rate indication, a blind hole indicating closure is also provided on the upper surface of the valve body, which is the same size as the eccentric hole. When the eccentric hole is aligned with the outlet hole, the blind hole indicating flow rate, the through hole indicating flow rate, and the blind hole indicating closure are also aligned.

[0011] Using the above scheme, in order to facilitate the indication that the water outlet is completely closed, a blind hole indicating closure is opened at the same position as the flow indication through hole. As the water outlet is gradually closed, the blind hole indicating closure is gradually opened until the water outlet is completely closed, at which point the blind hole indicating closure is fully opened, thus indicating that the water outlet is completely closed.

[0012] In a preferred embodiment of a perforated eccentric water inlet valve with built-in flow rate indication, the flow rate indication through hole and the flow rate indication blind hole are each painted with a different color of paint on their respective outlines.

[0013] In order to clearly indicate the outlines of the flow indication through-hole and the flow indication blind hole, the above scheme is adopted by applying eye-catching paint to their respective outlines, so as to facilitate observation of the overlap between the flow indication through-hole and the flow indication blind hole.

[0014] In a preferred embodiment of a perforated eccentric water inlet valve with built-in flow rate indication, the bottom surface of the closed indicator blind hole is coated with paint of a different color than that of the flow rate indication through hole and the flow rate indication blind hole.

[0015] The blind hole indicating closure has the word "Closed" printed on its bottom surface inside.

[0016] In order to clearly indicate the location of the closed blind hole, a conspicuous paint is applied to the bottom surface of the hole to make it easy to see whether the water outlet is closed.

[0017] In a preferred embodiment of a perforated eccentric water inlet valve with built-in flow rate indication, a valve stem is rotatably mounted inside the valve body, extending beyond the valve cover. A drive gear located inside the valve body is fixed below the valve stem, and a driven gear meshes and rotates on one side of the drive gear. An eccentric coupling is fixedly connected to the driven gear.

[0018] The diameter of the driving gear is larger than that of the driven gear.

[0019] Using the above scheme, in order to achieve the rotation of the eccentric column door, the rotation of the eccentric column door can be achieved by rotating the valve stem, which is driven by the transmission between the driving gear and the driven gear.

[0020] In a preferred embodiment of a perforated eccentric water inlet valve with built-in flow rate indication, an upper valve clamp and a lower valve clamp that cooperate with the upper valve clamp are connected to the lower part of the valve body. The two ends of the upper valve clamp and the lower valve clamp are respectively fixed to the pipeline by fastening components, wherein the fastening components are bolts and nuts; a sealing gasket is fixed below the upper valve clamp.

[0021] By adopting the above solution, in order to facilitate the installation or disassembly of the valve body, fastening components are used to detachably install the upper valve clamp and the lower valve clamp onto the pipeline, which can quickly complete the installation and disassembly of the valve body.

[0022] After adopting the above technical solution, the beneficial effects of this utility model are:

[0023] 1. When adjusting the water flow rate, the eccentric water inlet valve with water-filled perforation can accurately determine the flow rate of the outlet by observing the degree of overlap between the flow rate indicator blind hole and the flow rate indicator through hole, which represents the degree of overlap between the eccentric hole and the outlet hole.

[0024] 2. To facilitate the indication that the water outlet is completely closed, a blind hole indicating closure is opened at the same position as the flow indication through hole. As the water outlet is gradually closed, the blind hole indicating closure is gradually opened until the water outlet is completely closed, at which point the blind hole indicating closure is fully opened, thus indicating that the water outlet is completely closed.

[0025] 3. In order to clearly show the outlines of the flow indication through-hole and flow indication blind hole, apply eye-catching paint to their respective outlines to facilitate observation of the overlap between the flow indication through-hole and flow indication blind hole.

[0026] 4. In order to clearly indicate the location of the closed blind hole, apply conspicuous paint to the bottom of the hole to make it easy to see whether the water outlet is closed;

[0027] 5. In order to achieve the rotation of the eccentric pillar door, the rotation of the eccentric pillar door can be achieved by rotating the valve stem, which is driven by the transmission between the driving gear and the driven gear.

[0028] 6. To facilitate the installation or removal of the valve body, fastening components are used to detachably install the upper and lower valve clamps onto the pipeline, allowing for quick assembly and disassembly of the valve body. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figures 1 to 7As shown, a perforated eccentric water inlet valve with its own flow rate indication includes a valve body 1 and a valve cover 2 that is detachably mounted on top of the valve body 1 using screws. Both the valve body 1 and the valve cover 2 have a water outlet 3 at the same location. A connector 4 is connected to the water outlet 3 of the valve cover 2. A sealing eccentric connecting gate 5 is rotatably mounted inside the valve body 1. An eccentric hole 6, the same size as the water outlet 3, is perforated through the eccentric connecting gate 5. Rotating the eccentric connecting gate 5 controls the opening and closing of the water outlet 3. The valve cover 2 has a flow indication through-hole 7 of the same size as the eccentric hole 6, and the upper surface of the eccentric connecting column gate 5 has a flow indication blind hole 8 of the same size as the eccentric hole 6. When the eccentric hole 6 and the outlet hole 3 are aligned in the same direction, the flow indication blind hole 8 and the flow indication through-hole 7 are also aligned in the same direction. If the eccentric connecting column gate 5 is rotated, the overlap between the flow indication blind hole 8 and the flow indication through-hole 7 is exactly the same as the overlap between the eccentric hole 6 and the outlet hole 3. When adjusting the water flow rate, the eccentric water inlet valve with perforation can accurately determine the flow rate of the outlet hole 3 by observing the overlap between the flow indication blind hole 8 and the flow indication through-hole 7.

[0040] like Figures 2 to 7 As shown, the upper surface inside the valve body 1 is also provided with a blind hole 9 indicating closure, which is the same size as the eccentric hole 6. When the eccentric hole 6 is aligned with the outlet hole 3, the flow indication blind hole 8, the flow indication through hole 7, and the closure indication blind hole 9 are also aligned. To facilitate indicating that the outlet hole 3 is completely closed, a closure indication blind hole 9 is provided at the same position as the flow indication through hole 7. As the outlet hole 3 is gradually closed, the closure indication blind hole 9 is gradually opened until the outlet hole 3 is completely closed, at which point the closure indication blind hole 9 is fully opened, thus indicating that the outlet hole 3 is completely closed.

[0041] like Figures 2 to 7 As shown, the flow indication through-hole 7 and the flow indication blind orifice 8 are painted with different colors of paint on their respective outlines; for example, the flow indication through-hole 7 is painted yellow, and the flow indication blind orifice 8 is painted red. In order to clearly indicate the outlines of the flow indication through-hole 7 and the flow indication blind orifice 8, conspicuous paint is applied to their respective outlines, thereby facilitating the observation of the degree of overlap between the flow indication through-hole 7 and the flow indication blind orifice 8.

[0042] like Figures 2 to 7 As shown, the closed indicator blind hole 9 has a different color of paint, such as green, applied to its inner bottom surface compared to the flow indicator through hole 7 and the flow indicator blind hole 8; the word "Closed" is printed on the inner bottom surface of the closed indicator blind hole 9. In order to clearly indicate the location of the closed indicator blind hole 9, a conspicuous paint is applied to its inner bottom surface to make it easy to know whether the water outlet hole 3 is in the closed state.

[0043] like Figure 3 As shown, a valve stem 10 is rotatably mounted inside the valve body 1, extending beyond the valve cover 2. A drive gear 11 is fixed below the valve stem 10 and located inside the valve body 1. A driven gear 12 meshes with the drive gear 11 on one side, and an eccentric pivot door 5 is fixedly connected to the driven gear 12. The diameter of the drive gear 11 is larger than the diameter of the driven gear 12. To achieve the rotation of the eccentric pivot door 5, the valve stem 10 is rotated, and the rotation is achieved through the transmission between the drive gear 11 and the driven gear 12.

[0044] like Figure 1 As shown, an upper valve clamp 13 and a lower valve clamp 14 that cooperate with the upper valve clamp 13 are welded to the lower part of the valve body 1. The two ends of the upper valve clamp 13 and the lower valve clamp 14 are respectively fixed to the pipeline by fastening components, wherein the fastening components are bolts and nuts; a sealing gasket 15 is bonded and fixed to the lower part of the upper valve clamp 13. In order to facilitate the installation or disassembly of the valve body 1, the upper valve clamp 13 and the lower valve clamp 14 are detachably installed on the pipeline by using fastening components, so that the valve body 1 can be quickly disassembled and assembled.

[0045] The working principle of this utility model:

[0046] In application, the upper valve clamp 13 and lower valve clamp 14 are detachably installed on the pipeline using fastening components, which quickly completes the installation of the valve body 1. By drilling a hole into the pipeline inside the outlet hole 3, once the hole is successfully drilled, the water in the pipeline can be opened. After the outlet hole 3 is completely closed by rotating the eccentric connecting column gate 5, the connecting pipe is installed on the docking nozzle 4 to complete the drilling operation with water.

[0047] During use, the water outlet 3 and eccentric hole 6 are obstructed by the connecting pipe, making observation impossible. Operators cannot accurately determine the degree of overlap between the water outlet 3 and eccentric hole 6. In this case, the degree of overlap between the flow indicator blind hole 8 and the flow indicator through hole 7 represents the degree of overlap between the eccentric hole 6 and the water outlet 3, thus allowing for accurate determination of the flow rate of the water outlet 3. When the water outlet 3 is fully open, as... Figures 2 to 3 As shown; when the three water outlet sections are open, as... Figures 4 to 5 As shown; when water outlet 3 is completely closed, as Figures 6 to 7 As shown.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
