Description

Technical Field

[0001] This utility model relates to the field of flow regulating valve technology, and in particular to a multi-point positioning and guiding flow regulating valve. Background Technology

[0002] Due to their simple structure and low failure rate, hose flow control valves are increasingly widely used in pipelines in industries such as mining, petroleum, and chemical processing. However, due to their unique structural characteristics, hose flow control valves are generally used with a power mechanism that operates vertically or at a small angle. Insufficient vertical space or excessive installation angle can affect their applicable operating conditions and reliability.

[0003] In addition, during the clamping process of most hose flow regulating valves, especially large-sized hose clamp valves, the guide rod is too long, which makes it easy for the guide rod to wobble and obstruct the operation. The sealed valve body makes it difficult to find the fault point. Over time, the guide rod will deform, the adjustment will be obstructed, and the normal use of the hose clamp valve will be affected.

[0004] To address this issue, this application presents a multi-point positioning and guiding flow regulating valve. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this utility model provides a multi-point positioning and guiding flow regulating valve.

[0006] A multi-point positioning and guiding flow regulating valve, comprising a valve body, characterized in that:

[0007] The valve body is an integral welded structure with copper sleeves at both ends of its top mounting surface. A landing gear is mounted on the valve body, and a power mechanism is installed on the flange of the landing gear. The power mechanism is connected to drive a power screw for lifting. A guide rod passes through the copper sleeve. A rubber tube is provided in the valve body. An upper clamping roller and a lower clamping roller are symmetrically arranged on the side from which the rubber tube comes in. The upper clamping roller has copper sleeves at both ends that are fitted onto the guide rod, and the lower clamping roller is fixedly connected to the bottom end of the guide rod. A U-shaped positioning block is provided in the valve body at the center line of the rubber tube, and the guide rod passes through the positioning block. End flanges are provided at both ends of the valve body for fixing the rubber tube.

[0008] Furthermore, in order to better realize this utility model, when the power screw drives the upper clamping roller to rise and fall along the guide rod, the lower clamping roller moves symmetrically in the opposite direction due to the reaction force of the rubber tube, thereby clamping or releasing the rubber tube.

[0009] Furthermore, in order to better realize this utility model, the guide rod forms an axial positioning reference through the copper sleeve at the top of the valve body and the copper sleeves at both ends of the upper clamping roller.

[0010] Furthermore, in order to better realize this utility model, the inner wall of the U-shaped structure of the positioning block is fitted with the guide rod with a clearance to limit the radial deflection of the guide rod.

[0011] Furthermore, in order to better realize this utility model, the landing gear, guide rod and lower clamping roller are fixedly connected into an integrated structure by nuts.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes a multi-point positioning and guiding flow regulating valve. A power screw drives the upper clamping roller, which, under the reaction force of the hose compression, drives the lower clamping roller and lifting frame to move symmetrically in opposite directions around the hose's centerline, thus achieving the clamping and releasing of the hose by the upper and lower clamping rollers. The copper sleeves at both ends of the upper clamping roller and valve body serve as axial positioning references for the guide rod, improving its passability and smoother operation. A positioning block fixed to the valve body at the hose's centerline acts as an auxiliary positioning point, effectively preventing radial sway of the guide rod and preventing obstruction during its vertical movement, thereby improving the stability and safety of the hose flow regulating valve. After optimization, multi-point positioning effectively improves the guide rod's positioning and deformation dimensional changes, allowing the flow regulating valve to be installed at angles exceeding the original recommendations even in space-constrained conditions.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Figures 1-3 This is a specific embodiment of the present invention, which is a multi-point positioning and guiding flow regulating valve. The valve body 1 is an integral welded structure, ensuring the structural stability and consistency of the valve body 1 with reference. The top mounting surface of the valve body 1 is equipped with copper sleeves 9 at both ends for the guide rod to pass through. The landing gear 2 is equipped with a power mechanism on the flange, which drives the power screw 6 to rise and fall. The upper clamping roller 7 has through holes at both ends, and copper sleeves 9 are installed in the holes. The guide rod 5 passes through the top mounting surface of the valve body and the copper sleeves 9 at both ends of the upper clamping roller 7, and is connected and fixed to the lower clamping roller 8, forming an integral structure with the landing gear 2, the guide rod 5, and the lower clamping roller 8. The power screw 6 is connected to the upper clamping roller 7, and drives the upper clamping roller 7 to rise and fall along the guide rod 5 under the drive of the power mechanism. The positioning block 10 is a U-shaped structure, installed on the valve body 1. The guide rod 5 passes through the positioning block 10, which can prevent the guide rod 5 from radially deflecting and ensure the stability of the guide. The U-shaped design facilitates the disassembly and repair of the positioning block 10 and ensures that it is coaxial with the guide rod 5. The end flange 4 has a semi-circular open structure and is installed at both ends of the valve body 1 to fix the hose 3. Its open structure facilitates the disassembly and maintenance of the hose 3. The hose 3 is installed between the upper and lower clamping rollers and is fixedly installed to the valve body 1 through the end flange 4.

[0022] When the power mechanism drives the upper clamping roller 7 to move downwards, the lower clamping roller 8 and the lifting frame 2 move upwards under the reaction force of the extrusion pressure on the hose 3, and the upper and lower clamping rollers are aligned and clamped. Conversely, they open. The upper and lower clamping rollers move symmetrically up and down about the horizontal centerline of the hose 3 to maintain the centerline of the hose 3 at the same height as the centerline of the pipeline. By compressing and changing the cross-sectional area of ​​the hose 3, a good adjustment effect is achieved.

[0023] The valve body 1 serves as the mounting base. The guide rod 5 passes through the copper sleeves 9 at both ends of the upper mounting surface of the valve body 1 and is fixed together with the lower clamping roller 8 and the landing gear 2 by nuts. The upper clamping roller 7 can move up and down along the guide rod 5 through the copper sleeves 9 at both ends. The power screw 6 drives the upper clamping roller 7 to move up and down. Under the reaction force of the squeezing of the hose 3, the lower clamping roller 8 and the landing gear 2 move symmetrically in opposite directions about the center line of the hose 3, realizing the clamping and loosening of the hose by the upper and lower clamping rollers, thus playing the role of opening and closing the valve and regulating the flow.

[0024] The upper clamping roller 7 and the copper sleeves 9 at both ends of the valve body improve the passability of the guide rod 5 during operation, making the operation smoother. The positioning block 10, which is fixed on the valve body 1 and located at the center line of the hose, serves as an auxiliary positioning point and can effectively prevent the guide rod 5 from radially deflecting. In particular, when the flow regulating valve exceeds the original recommended installation angle, it effectively prevents the guide rod from being blocked or stuck during its up and down movement, realizes the opening and closing of the upper and lower clamping rollers, and improves the stability and safety of the hose flow regulating valve.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
