Description

Technical Field

[0001] This utility model belongs to the field of electric valve technology, and in particular relates to an electric control valve that is easy to install. Background Technology

[0002] An electric valve is a device that uses an electric actuator to control the opening, closing, or regulation of a valve. It can be divided into two parts: the upper part is the electric actuator, and the lower part is the valve. Electric valves are commonly used in industrial pipeline systems that require remote control, automation, or precise regulation, as well as in some specific applications.

[0003] Electric valves provide high-precision valve position control and flow regulation, ensuring stable system operation and accurate process parameters. They enable remote monitoring and operation, improving the system's automation level, reducing manual operation costs and errors, and responding to control commands in a short time. They are suitable for application scenarios that require rapid adjustment and response to changes.

[0004] Currently, in practical applications, when electric valves are connected to external pipelines, the weight and volume of the pipes create resistance during connection. Workers must simultaneously support the pipes while rotating the valve to connect it via threads. This process is inconvenient, difficult, time-consuming, and labor-intensive, and may lead to inaccurate connections, leaks, or weak connections. Therefore, there is an urgent need to design an easily installable electric control valve. Utility Model Content

[0005] This utility model provides an electrically controlled valve with a reasonable structural design that is easy to install, addressing the technical problems existing in prior art. This utility model ensures a tight and stable connection between the pipeline and the electric valve, offering convenient installation and meeting practical application needs. It effectively avoids problems such as leakage or weak connections caused by inaccurate docking, improving the overall system's operating efficiency and safety.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: an easy-to-install electric control valve includes an electric valve component, with connecting threaded caps fixedly connected to both ends of the electric valve component, and a plurality of mounting guide rods arranged parallel to the axial direction of the electric valve component installed between the two connecting threaded caps. Two sliding support components are respectively installed on the mounting guide rods on both sides of the electric actuator, and the position of each sliding support component is adjustable. A sliding mounting device is slidably connected to each sliding support component, and a pipe clamping device is installed at the outer end of each sliding mounting device for centering and clamping the pipe component. A plurality of return springs are installed between the corresponding sliding support component and the sliding mounting device. The pipe clamping device includes a shell structure, with a through groove for the pipe to pass through at the center of the shell structure. A plurality of pipe clamping roller mechanisms are arranged in a circumferentially distributed manner in the through groove. It also includes a centering drive assembly installed in the shell structure for driving the plurality of pipe clamping roller mechanisms to synchronously converge inward or expand outward.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides an easy-to-install electric control valve. Through the set pipe clamping device, the pipe can be centered and clamped. Since the centering drive component in the pipe clamping device can drive several pipe clamping rollers to synchronously converge inward or expand outward, it ensures that the pipe clamping device is suitable for pipes of different diameters, improving the applicability of the electric control valve. Through the set sliding installation device and several return springs, the pipe end can be tightly abutted against the connecting threaded cap, facilitating the worker to rotate the pipe to achieve a threaded connection between the pipe and the electric valve, reducing the physical burden on personnel, lowering installation costs, and improving the convenience and practicality of installation. Under the action of the centering drive component, several pipe clamping rollers can center and clamp the pipe, ensuring coaxial connection between the pipe and the connecting threaded cap, improving the accuracy and stability of installation, and avoiding problems such as leakage or weak connection caused by inaccurate connection, thereby improving the overall system's operating efficiency and safety. This utility model greatly simplifies the installation process, eliminating the tedious steps of workers lifting the pipe and rotating the valve in traditional installations, reducing installation difficulty, and improving installation efficiency. This effectively avoids problems such as leakage or weak connection caused by inaccurate docking, and improves the overall system's operating efficiency and security.

[0020] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail:

[0021] Please see Figure 1 The easy-to-install electric control valve of this utility model includes an electric valve component 6, and connecting threaded caps are fixedly connected to both ports of the electric valve component 6. See further details. Figure 5 Several mounting guide rods 7, arranged parallel to the axial direction of the electric valve component 6, are installed between two connecting threaded caps. For example... Figure 1 As shown, two sliding support members 3 are respectively installed on the mounting guide rod 7 on both sides of the electric actuator. The position of each sliding support member 3 is adjustable. That is, each sliding support member 3 has a through hole through which several mounting guide rods 7 can pass. The end of each mounting guide rod 7 is provided with a thread. The sliding support members 3 are locked to the 7 by nuts and washers.

[0022] Each sliding support 3 is slidably connected to a sliding mounting device, and each sliding mounting device is equipped with a pipe clamping device 1 at its outer end for centering and clamping the pipe fitting. Several return springs 4 are installed between the corresponding sliding support 3 and the sliding mounting device.

[0023] The aforementioned sliding installation device includes a plurality of sliding rods 2 slidably passing through the sliding support 3 and arranged parallel to the installation guide rods 7. A rod mounting plate 5, slidably connected to the mounting guide rods 7, is fixed to the inner end of each sliding rod 2. A plurality of return springs 4 are respectively passed through the sliding rods 2 and located between the sliding support 3 and the rod mounting plate 5. A pipe clamping device 1 is installed at the outer end of each sliding rod 2.

[0024] See further Figure 2 The aforementioned pipe clamping device 1 includes a shell structure, with a through groove at the center of the shell structure for the pipe to pass through, and a plurality of pipe clamping roller mechanisms 1-1 arranged circumferentially in the through groove. It also includes a centering drive assembly 1-2 installed in the shell structure for driving the plurality of pipe clamping roller mechanisms 1-1 to converge inward or expand outward synchronously.

[0025] The aforementioned pipe clamping roller mechanism 1-1 comprises four sets, distributed at equal angles along the circumference. Each pipe clamping roller mechanism 1-1 includes two opposing mounting plates, with rollers made of rubber rotatably connected between them. During operation, the rubber rollers ensure sufficient clamping force while preventing damage to the pipe during installation. This design achieves a user-friendly effect, making the installation process safer and more reliable.

[0026] like Figure 3 and Figure 4 As shown, the aforementioned centering drive assembly 1-2 includes an annular bevel gear 1-2-5 rotatably connected within the housing structure, and a plurality of circumferentially distributed sliding seats 1-2-8 movably connected to the annular bevel gear 1-2-5 for mounting a plurality of tube-clamping rolling mechanisms 1-1. Each sliding seat 1-2-8 is provided with a plurality of protruding teeth 1-2-7, and a helical groove 1-2-6 is formed on the end face of the annular bevel gear 1-2-5, with the protruding teeth 1-2-7 on each sliding seat 1-2-8 located within the helical groove 1-2-6. A plurality of circumferentially distributed transmission bevel gears 1-2-4, meshing with the annular bevel gear 1-2-5, are rotatably connected within the housing structure, and each transmission bevel gear 1-2-4 is rotatably connected to the housing structure via rolling bearings. The centering drive assembly 1-2 also includes a rotary drive mechanism for driving the rotation of the annular bevel gear 1-2-5.

[0027] The aforementioned rotary drive mechanism includes a drive transmission pair 1-2-1 mounted on the housing structure. The drive transmission pair 1-2-1 is a worm gear transmission pair, mainly comprising a housing structure mounted on the housing structure. Within the housing structure, a meshing worm and a turbine are rotatably connected. The input shaft of the worm is connected to the drive component 1-2-9, and the output shaft of the worm is connected to the driving bevel gear 1-2-2. The driving bevel gear 1-2-2, which meshes with the annular bevel gear 1-2-5, is mounted on the output shaft of the drive transmission pair 1-2-1, and the drive component 1-2-9 is mounted on the input shaft of the drive transmission pair 1-2-1.

[0028] In addition, the centering drive assembly 1-2 also includes a guide mounting sleeve 1-2-3 disposed in the central through groove of the housing structure. Several sliding through grooves 1-2-10 are provided on the outer peripheral wall of the guide mounting sleeve 1-2-3, and several sliding seats 1-2-8 are respectively slidably inserted into the several sliding through grooves 1-2-10. The aforementioned annular bevel gear 1-2-5 is located between the guide mounting sleeve 1-2-3 and the housing structure.

[0029] like Figure 3As shown, the above-mentioned shell structure includes an outer shell 1-3 and an outer shell 1-4 that are mated together. The outer shell 1-3 and the outer shell 1-4 are locked together by bolts and lock nuts. Several receiving grooves are provided on the mating surfaces of the outer shell 1-3 and the outer shell 1-4 for the sliding seat 1-2-8 to pass through.

[0030] Working principle:

[0031] Before installation begins, personnel first pull the pipe clamping device 1 outwards in sequence, causing it to move horizontally along with the several pipe-clamping roller mechanisms 1-1 installed within its groove. During this movement, the return springs 4 are compressed and placed in a squeezed state. Next, personnel align the central area formed by the pipe-clamping roller mechanisms 1-1 with the end of the external pipe and rotate the drive component 1-2-9, causing the roller mechanisms 1-1 to converge inwards and clamp the pipe. Once the pipe is successfully clamped, personnel release their grip, and the return springs 4 return to their original position and begin functioning. Under the elastic force, the pipe clamping device 1, holding the external pipe, moves the pipe, causing one end of the pipe to abut against the inner cavity of the threaded cap installed at the end of the electric valve component 6. Finally, by simply rotating the pipe, a threaded connection is achieved between the pipe and the threaded cap, completing a quick and stable installation.
