Description

Technical Field

[0001] The utility model relates to the technical field of electric valves, in particular to an electric valve that is easy to install. Background Art

[0002] An electric valve is a device that uses an electric actuator to drive the opening and closing of a valve. It is a high-end product among automatic control valves. Electric valves not only have the on-off function of traditional manual valves, but also can achieve valve position adjustment through a modulating electric valve, precisely controlling parameters such as the flow, pressure, and temperature of the medium in the pipeline. The operating principle of an electric valve is relatively complex. It first receives signals from the control system through an electric device, then converts these signals into mechanical energy to drive the valve to open or close or adjust the valve. The stroke of the electric actuator can be divided into two types: 90° angular stroke and linear stroke. Depending on the specific valve type and application, it can also meet the special requirements of 180°, 270°, and 360° full stroke. This design enables electric valves to adapt to various complex working conditions and achieve efficient and accurate fluid control.

[0003] Electric valves occupy a vital position in their application field. As a key link in fluid control, their ease of installation and sealing performance have a decisive impact on the overall system's operating efficiency and safety. In particular, existing electric valves present challenges when handling pipes of varying sizes and weights, particularly during the crucial connection between the electric valve and the external piping.

[0004] Specifically, when existing electric valves are actually used, personnel need to connect external pipes to them. Due to the weight and volume of the pipes, there will be a certain amount of resistance when connecting them to the valve. For example, personnel need to lift the pipe to a certain extent while rotating the electric valve to tightly connect the two through the thread. This process is not only complicated to operate, but also requires a lot of physical strength and time, which increases the difficulty of installation for personnel and reduces installation efficiency. More seriously, due to the heavy weight of the pipes and the inconvenience of operation, it may also lead to inaccurate docking, leakage, or loose connections.

[0005] Therefore, in response to the many deficiencies in the existing technology, we propose an easy-to-install electric valve to solve these problems. This new electric valve should improve installation convenience and sealing performance, while better meeting the needs of high-efficiency installation. Utility Model Content

[0006] The purpose of the utility model is to provide an electric valve that is easy to install, which solves the problem in the prior art that during actual use of the existing electric valve, personnel need to connect the external pipe with the valve, and due to the weight of the pipe, there will be a certain resistance when connecting with the valve. For example, personnel need to lift the pipe to a certain extent and then rotate the electric valve to make a threaded connection between the two, which increases the installation difficulty of personnel and reduces the installation efficiency of personnel.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Reference Figure 1-5 An easy-to-install electric valve includes a pipe 2, with a valve body 1 fixedly connected to the upper outer ring of the pipe 2. The pipe 2 is the core component of the electric valve and is used for fluid transmission. It connects the valve body 1 and the connecting threaded caps 3 at both ends, forming the main structure of the valve. The connecting threaded caps 3 are fixedly connected to both ends of the pipe 2, providing connection interfaces with external pipes or equipment. Through the threaded connection, the electric valve can be easily connected to other pipes or equipment, achieving smooth fluid transmission.

[0025] Both sides of the outer ring of the pipe 2 are sleeved with movable rings 4. The movable rings 4 are sleeved on both sides of the outer ring of the pipe 2 and are key components for the easy installation of the electric valve. By pulling the movable ring 4, the notched clamp 7 can be driven to move horizontally, thereby achieving rapid clamping and positioning of the external pipe. Three straight rods 8 are fixedly connected to one side of the connecting threaded cap 3. One end of the straight rod 8 is fixedly connected to one side of the connecting threaded cap 3, and the other end passes through the through hole 10 on the movable ring 4 and is fixedly connected to the limiting plate 11. The straight rod 8 plays a guiding and limiting role, ensuring that the movable ring 4 can move along the predetermined trajectory during the pulling process and maintain a stable connection state. Three through holes 10 are opened on one side of the movable ring 4. The through holes 10 are opened on one side of the movable ring 4 to accommodate the penetration of the straight rods 8. The cooperation between the through hole 10 and the straight rod 8 enables the movable ring 4 to maintain a stable connection during the pulling process, and allows the movable ring 4 to move horizontally on the straight rod 8. One end of the straight rod 8 passes through the corresponding through hole 10 and is fixedly connected to a limit plate 11. The limit plate 11 is fixedly connected to one end of the straight rod 8 and is used to limit the movement range of the movable ring 4. When the movable ring 4 is pulled to the extreme position, the limit plate 11 will prevent it from moving further, thereby ensuring the safe and reliable installation process of the electric valve. A notch clamp 7 is provided on one side of the movable ring 4. The notch clamp 7 is provided on one side of the movable ring 4 and is used to clamp and position the external pipe. When the movable ring 4 is pulled, the notch clamp 7 will move accordingly and clamp the external pipe through its notch. The model of the valve body 1 is Q941 F-16P.

[0026] Furthermore, the outer ring of the movable ring 4 is fixedly connected to a plurality of connecting rods 5, one side of which is fixedly connected to a short block 6, one side of which is fixedly connected to the outer ring of a corresponding notched clamping block 7. Through the coordinated arrangement of the movable ring 4, connecting rods 5, short blocks 6, and notched clamping blocks 7, during the workflow, when a person pulls the movable ring 4, the movable ring 4 drives the short blocks 6 to move via the connecting rods 5, thereby causing the notched clamping blocks 7 to produce horizontal displacement. This arrangement allows the notched clamping blocks 7 to easily clamp the external pipe, providing a foundation for subsequent automatic resetting and tight connection.

[0027] Furthermore, a return spring 9 is mounted on the outer ring of the straight rod 8. One end of the return spring 9 is fixedly connected to one end of the corresponding connecting threaded cap 3, and the other end of the return spring 9 is fixedly connected to one end of the corresponding movable ring 4. Through the coordinated arrangement of the straight rod 8 and the return spring 9, during the working process, when the movable ring 4 is pulled, the straight rod 8 will penetrate the through hole 10 on the movable ring 4 and compress the return spring 9. When the operator releases his hand, the elastic force of the return spring 9 will push the movable ring 4 and the notched clamp 7 connected to it to reset, thereby driving the pipe to move and making one end of the pipe tightly against the connecting threaded cap 3. This arrangement achieves the effect of automatic reset and tight connection, improving the convenience and efficiency of installation.

[0028] Furthermore, the two movable rings 4 are symmetrically located on either side of the outer circumference of the pipe 2. This arrangement allows the two movable rings 4 and their connected notched clamping blocks 7 to evenly distribute force during operation, jointly clamping and positioning the pipe and ensuring a secure and airtight installation. This arrangement improves installation stability and reliability, avoiding connection problems caused by uneven force.

[0029] Furthermore, the notched clamp 7 is made of plastic, and both connecting threaded caps 3 are connected to the inner cavity of the pipe 2. By making the notched clamp 7 of plastic, the plastic notched clamp 7 ensures sufficient clamping force during the workflow while avoiding damage to the pipe during installation. This setting achieves the effect of humanized design, making the installation process safer and more reliable. By making the two connecting threaded caps 3 connected to the inner cavity of the pipe 2, during the workflow, when the pipe and the connecting threaded cap 3 are connected by threaded engagement, the fluid can smoothly pass through the pipe 2 and the connecting threaded cap 3, achieving effective control of the fluid by the electric valve. This setting ensures the smooth passage and effective control of the fluid, meeting the needs of the electric valve in practical applications.

[0030] In summary: before the installation begins, the personnel first pull the movable ring 4 in sequence. This action causes the movable ring 4 to drive its corresponding notch clamp 7 to displace in the horizontal direction. At this time, due to the movement of the movable ring 4, the reset spring 9 is compressed and is in an extruded state. Next, the personnel aligns the external pipe with the notch on the notch clamp 7, and clamps the pipe into the inner cavity of the notch clamp 7 through the notch. When the pipe is successfully clamped in, the personnel releases their hands. At this time, the external force is lost and the reset spring 9 begins to play its role. Under the elastic force of the reset spring 9, the notch clamp 7 that clamps the external pipe will drive the pipe to displace, so that one end of the pipe is against the inner cavity side of the corresponding connecting threaded cap 3. Finally, the personnel only needs to rotate the pipe, and the pipe and the connecting threaded cap 3 achieve the connection effect of threaded connection, and the quick and stable installation operation is completed.

[0031] Beneficial effects:

[0032] By providing a movable ring 4 and a connected notched clamp 7, the electric valve of this utility model achieves rapid clamping and positioning of pipes. This design greatly simplifies the installation process, eliminating the tedious steps required to lift the pipe and rotate the valve in traditional installation, thereby reducing installation difficulty and improving installation efficiency. This directly solves the technical problem mentioned in the background technology: "the operator needs to lift the pipe and rotate the electric valve at the same time, which is complicated and physically demanding."

[0033] The design of the return spring 9 ensures that during installation, once the pipe is inserted into the notched clamp 7, the spring force of the return spring 9 automatically pushes the notched clamp 7 and the pipe forward until the pipe is firmly seated against the connecting threaded cap 3, eliminating the need for continuous force. This automated process not only reduces the physical burden on operators but also improves installation accuracy and stability.

[0034] The notched design of the notched clamp 7 allows for easy insertion of the pipe, which is then tightly clamped by the return spring 9, ensuring a secure connection between the pipe and the electric valve. This design effectively avoids problems such as leaks or loose connections caused by inaccurate docking, thereby improving the overall system's operational efficiency and safety. Through the coordinated action of the movable ring 4, the notched clamp 7, and the return spring 9, this electric valve achieves fast and secure pipe installation without the need for additional tools or auxiliary equipment, reducing installation costs and improving both ease and practicality.
