Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure regulating equipment technology, and in particular to a pressure regulating valve with automatic flow control. Background Technology
[0002] Automatic flow control pressure regulating valves are devices that automatically adjust the flow rate of fluid according to changes in system pressure to maintain stable system pressure. In industrial automation process control, pressure regulating valves are used to precisely control parameters such as the flow rate and pressure of media, and are key equipment to ensure production efficiency and product quality. Automatic flow control pressure regulating valves have a wide range of applications and good development prospects. With continuous technological innovation and market expansion, this industry will usher in more development opportunities and challenges.
[0003] In existing technology, pressure regulating valves, as precision fluid control devices, are designed with connection holes at both ends for connection to pipelines or other equipment to ensure smooth fluid transmission. However, in practical applications, when these connection holes are not connected, they are often directly exposed to the external environment without necessary protective measures. This direct exposure leads to several adverse consequences: First, the connection holes become channels for dust, impurities, and fine particles to enter. Over time, these foreign substances gradually accumulate inside the valve, especially in hard-to-clean dead corners, increasing internal contamination and causing a decline in sealing performance. Firstly, it affects the normal opening and closing action of the valve and the accuracy of fluid control. Secondly, exposed metal surfaces are prone to oxidation reactions with oxygen in the air, forming rust. This chemical change will erode the valve's material structure, weakening its mechanical strength and durability. Especially for some high-sensitivity or special material pressure regulating valves, even slight corrosion can cause irreversible damage to their function. Furthermore, long-term environmental factors (such as temperature and humidity changes, ultraviolet radiation, etc.) also accelerate the aging process of the material around the connection hole, causing the originally tightly fitted parts to loosen or crack, further reducing the reliability and service life of the equipment. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic flow control pressure regulating valve.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic flow control pressure regulating valve, comprising a pressure regulating body, a medium port fixed at the bottom end of the pressure regulating body, a base fixing cylinder fixed at one end of the medium port, a side shaft arc groove formed on the circumferential surface of the base fixing cylinder, a hexagonal L-shaped groove formed on one side of the base fixing cylinder, an L-shaped limiting member slidably connected to the inner wall of the hexagonal L-shaped groove, a tangent triangular member fixed at one end of the L-shaped limiting member, a top sliding limiting post fixed on one side of the tangent triangular member, a control rotation emptying member rotatably connected to the circumferential surface of the base fixing cylinder, an end circular sliding groove formed in a circular array on the surface of the control rotation emptying member, and the inner wall of the end circular sliding groove slidably connected to the circumferential surface of the top sliding limiting post.
[0006] Preferably, a beveled fixed cylinder is fixed to one side of the base fixed cylinder, a T-shaped ring is fixed to one end of the beveled fixed cylinder, and a beveled moving cylinder is provided at one end of the beveled fixed cylinder. A T-shaped groove is formed on the inner wall of one end of the beveled moving cylinder, and the inner wall of the T-shaped groove is slidably connected to the surface of the T-shaped ring. In the prior art, the medium port of the pressure regulating body is designed to always have a fixed orientation. This design will encounter some challenges in practical applications. When the space of the installation environment is relatively narrow or there are angular deviations such as left-right or high-low between the equipment, the fixed orientation of the medium port will make docking very difficult. This not only limits the applicability of the equipment, making it difficult to adapt to diverse application scenarios, but also puts forward higher technical requirements for operators. In order to ensure correct installation and effective operation, more professional technicians are needed to guide or directly participate in the installation process, thereby increasing human resources. In addition to cost, during subsequent use, if the position needs to be adjusted or related components replaced, the invariable orientation of the medium port will cause inconvenience to maintenance work, further increasing the overall maintenance cost. Therefore, although the current design can meet certain functional requirements, in the long run, its limitations will lead to additional economic burdens and affect user experience. To address these issues, this utility model adopts the method of installing a slanted fixed cylinder. This allows the operator to rotate the slanted moving cylinder when connecting equipment with angular deviations such as left-right or high-low between the moving cylinder and the pressure regulating body. The slanted moving cylinder rotates at one end of the slanted fixed cylinder by relying on the T-slot and T-ring to easily change the orientation of the slanted moving cylinder, thereby adapting the medium port to different installation environments and improving the applicability of the equipment.
[0007] Preferably, a control extension handle is fixed to the circumference of the control rotation component. In the prior art, the control rotation component is obscured after the oblique-cutting fixed cylinder is installed, requiring operators to use additional motors or tools to control it. This design flaw not only increases the complexity of operation but also requires users to have higher technical proficiency and professional knowledge. For non-professional users, these additional operating steps may seem cumbersome and difficult to understand, thus reducing the overall user experience. In addition, frequent use of additional tools may also increase equipment wear and maintenance costs, further affecting user satisfaction and efficiency. To address these issues, this utility model solves the problem by installing a control extension handle, enabling operators to conveniently operate the equipment through the control extension handle, thereby improving the user experience.
[0008] Preferably, one end of the control extension handle has a through hole, which allows workers to use the through hole to hang ropes for counterweights or use other tools, thereby ensuring its shielding effect and improving the stability of the equipment.
[0009] Preferably, both ends of the side shaft arc groove are fixed with arc end pads, which reduces the collision and wear between components and improves the service life of the equipment.
[0010] Preferably, corner sealing gaskets are fixed on both sides of the cut-edge triangular piece, which realizes the sealing effect of the component through the corner sealing gaskets, increases the water resistance performance, and improves the service life of the equipment.
[0011] Preferably, both ends of the inner wall of the end-circular groove are set as semi-circular edges, which reduces wear between components and improves the service life of the equipment.
[0012] Beneficial effects:
[0013] 1. In existing technology, pressure regulating valves, as precision fluid control devices, are designed with connection holes at both ends for connection to pipelines or other equipment to ensure smooth fluid transmission. However, in practical applications, when these connection holes are not connected, they are often directly exposed to the external environment without necessary protective measures. This direct exposure leads to several adverse consequences: First, the connection holes become channels for dust, impurities, and fine particles to enter. Over time, these foreign substances gradually accumulate inside the valve, especially in hard-to-clean dead corners, increasing internal contamination, reducing sealing performance, and affecting the valve's normal opening and closing actions and the accuracy of fluid control. Second, exposed metal surfaces are prone to oxidation reactions with oxygen in the air, forming rust. This chemical change corrodes the valve's material structure, weakening its mechanical strength and durability, especially for... For some highly sensitive or specially made pressure regulating valves, even slight corrosion can cause irreversible damage to their function. Furthermore, long-term environmental factors accelerate the aging process of the materials around the connection holes, causing loosening or cracks in the originally tightly fitted parts, further reducing the reliability and service life of the equipment. To address these issues, this utility model uses a truncated triangular piece to solve the problem. When the pressure regulating body is not in use, the rotating control piece causes the end circular groove to move the top sliding limit column closer to the center. As the truncated triangular piece rotates, it converges towards the center, blocking the medium port and preventing dust and powder from entering. This keeps the inner wall of the equipment clean even when it is not in use for a long time, thus extending its service life. At the same time, when restarting, only a simple cleaning is needed for quick use, improving work efficiency and achieving the effect of extending the service life of the equipment.
[0014] 2. In existing technologies, the medium port of the pressure regulating body is designed to always have a fixed orientation. This design presents several challenges in practical applications. When the installation environment is confined or there are angular deviations between devices (such as left-right or high-right), the fixed medium port orientation makes docking extremely difficult. This not only limits the applicability of the device, making it difficult to adapt to diverse application scenarios, but also places higher technical demands on operators. To ensure correct installation and effective operation, more specialized technicians are needed to guide or directly participate in the installation process, thus increasing human resource costs. Furthermore, during subsequent use, if it is necessary to adjust the position or replace related components, the fixed medium port orientation will hinder the process. The characteristics of this feature also bring inconvenience to maintenance work, further increasing the overall maintenance cost. Therefore, although the current design can meet certain functional requirements, in the long run, its limitations will lead to additional economic burdens and affect user experience. To address this problem, this utility model adopts the method of installing a slanted fixed cylinder. When the operator needs to connect equipment with angular deviations such as left-right or high-low between the device and the pressure regulating body, the slanted moving cylinder can be rotated. The slanted moving cylinder relies on the T-slot and T-ring to rotate at one end of the slanted fixed cylinder, thereby conveniently changing the orientation of the slanted moving cylinder. This allows the medium port to adapt to different installation environments, thereby improving the applicability of the equipment.
[0015] 3. In existing technologies, the control rotation mechanism is obstructed after the oblique-cutting fixed cylinder is installed, requiring operators to use additional motors or tools to control its operation. This design flaw not only increases operational complexity but also demands higher technical proficiency and professional knowledge from users. For non-professional users, these additional operating steps may seem cumbersome and difficult to understand, thus reducing the overall user experience. Furthermore, frequent use of additional tools may increase equipment wear and maintenance costs, further impacting user satisfaction and efficiency. To address these issues, this invention solves the problem by installing a control extension handle, enabling operators to conveniently operate the equipment through the control extension handle, thereby improving the user experience.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0027] Reference Figure 1-6An automatic flow control pressure regulating valve includes a pressure regulating body 1. A medium port 101 is fixed to the bottom of the pressure regulating body 1. A base fixing cylinder 2 is fixed to one end of the medium port 101. A side shaft arc groove 201 is opened on the circumference of the base fixing cylinder 2. A hexagonal L-shaped groove 202 is opened on one side of the base fixing cylinder 2. An L-shaped limiting member 203 is slidably connected to the inner wall of the hexagonal L-shaped groove 202. A tangent triangular member 204 is fixed to one end of the L-shaped limiting member 203. A top sliding limiting post 205 is fixed to one side of the tangent triangular member 204. A control rotation emptying member 206 is rotatably connected to the circumference of the base fixing cylinder 2. An end circular sliding groove 207 is opened in a circular array on the surface of the control rotation emptying member 206. The inner wall of the end circular sliding groove 207 is slidably connected to the circumference of the top sliding limiting post 205. A beveled fixed cylinder 3 is fixed to one side of the base fixed cylinder 2. A T-shaped ring 301 is fixed to one end of the beveled fixed cylinder 3. A beveled moving cylinder 302 is provided at one end of the beveled fixed cylinder 3. A T-shaped groove is opened on the inner wall of one end of the beveled moving cylinder 302. The inner wall of the T-shaped groove is slidably connected to the surface of the T-shaped ring 301. The medium port 101 of the pressure regulating body 1 is designed to always have a fixed orientation. This design will encounter some challenges in practical applications. When the space in the installation environment is relatively narrow or there are angular deviations such as left-right or high-low between the equipment, the fixed orientation of the medium port 101 will make docking very difficult. This not only limits the applicability of the equipment, making it difficult to adapt to diverse application scenarios, but also puts forward higher technical requirements for operators. In order to ensure correct installation and effective operation, more professional technicians are needed to guide or directly participate in the installation process, thereby increasing human resource costs. Furthermore, during subsequent use, if it is necessary to adjust the position or replace related components, the invariable orientation of the medium port 101 will cause inconvenience to maintenance work, further increasing the overall maintenance cost. Therefore, although the current design can meet certain functional requirements, in the long run, its limitations will lead to additional economic burdens and affect user experience. The solution is to install the oblique-cut fixed cylinder 3. When the operator needs to connect equipment with angular deviations such as left-right or high-low between the device and the pressure regulating body 1, the oblique-cut moving cylinder 302 can be rotated. The oblique-cut moving cylinder 302, relying on the T-slot and the T-ring 301, rotates at one end of the oblique-cut fixed cylinder 3, thereby conveniently changing the orientation of the oblique-cut moving cylinder 302. This allows the medium port 101 to adapt to different installation environments, thereby improving the applicability of the equipment.
[0028] A control circumferential handle 4 is fixed to the circumference of the control rotating part 206. Because the control rotating part 206 is obscured after the installation of the oblique-cutting fixed cylinder 3, operators need to use an additional motor or tool to control it. This design flaw not only increases operational complexity but also requires users to have higher technical proficiency and professional knowledge. For non-professional users, these additional operating steps may seem cumbersome and difficult to understand, thus reducing the overall user experience. Furthermore, frequent use of additional tools may increase equipment wear and maintenance costs, further affecting user satisfaction and efficiency. The installation of the control circumferential handle 4 solves this problem, allowing operators to easily operate the equipment and improving the user experience. A through hole 5 is provided at one end of the control circumferential handle 4, allowing operators to easily attach ropes or use other tools, thus ensuring its obscuration effect and improving equipment stability. Arc-end pads 6 are fixed to both ends of the side shaft arc groove 201, reducing collisions and wear between components and extending the equipment's lifespan. Both sides of the chamfered triangular component 204 are fixed with corner sealing gaskets 7, achieving a sealing effect through the components via the corner sealing gaskets 7, increasing water resistance, and thus extending the service life of the equipment. The inner walls of the end-circular sliding groove 207 are both designed with semi-circular edges, reducing wear between components and further extending the service life of the equipment.
[0029] The working principle of this utility model is as follows: When the operator is not using the pressure regulating body 1, the control rotation component 206 can be rotated to make the end round sliding groove 207 move the top sliding limit column 205 closer to the center. This causes the tangential triangular component 204 to rotate and converge towards the center, blocking the medium port 101, thereby preventing dust and powder from entering. This keeps the inner wall of the equipment clean even when it is not used for a long time, thus extending its service life. At the same time, when it is restarted, it can be quickly put into use after a simple cleaning, improving work efficiency. When the operator needs to connect equipment with angular deviations such as left-right or high-low between the pressure regulating body 1 and the device, the oblique cutting cylinder 302 can be rotated. The oblique cutting cylinder 302 relies on the T-slot and the T-ring component 301 to rotate at one end of the oblique cutting fixed cylinder 3, thereby conveniently changing the orientation of the oblique cutting cylinder 302, so that the medium port 101 can be adapted to different installation environments.
