[0002] Flowmeters are widely used in the industrial field, including industries such as petrochemical, water supply systems, and food processing. Their measurement accuracy and installation stability are directly related to the accuracy of flow measurement and the overall efficiency of the system. Since flowmeters usually need to work in high-pressure, high-temperature, or corrosive environments, any minor assembly error or improper connection may lead to data deviation, equipment failure, or safety hazards. Therefore, there is an urgent need in the industry for a more convenient and reliable connection solution to simplify the installation process, improve connection stability, and ensure sealing performance, thereby enhancing the measurement accuracy and long-term operation reliability of the flowmeter. Such a solution can not only optimize the user's maintenance experience but also reduce economic losses caused by equipment failures and improve the operating efficiency of the entire system.

[0003] However, the existing technologies still have the following deficiencies in use: The current connection methods in the market mainly adopt thread and welding forms. These methods often have problems of complexity and insufficient sealing performance during the installation process. In addition, after the steel pipe is installed, there is a lack of an effective connection method to enhance its stability, thus reducing the overall practicality and reliability.

[0004] Therefore, there is an urgent need for a ferrule joint applied to a flowmeter to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a ferrule joint applied to a flowmeter to solve the problems raised in the above background art.

A first threaded groove is formed on the outer wall of the threaded ring. An installation ring is fixedly connected to the outer wall of the joint body. A ferrule is fixedly connected to the side wall of the installation ring. A locking member is connected to the side wall of the installation ring.

[0008] As a preferred technical solution of the present application, a second threaded groove is formed on the outer wall of the installation ring, and a nut is threadedly connected to the outer wall of the installation ring through the second threaded groove.

[0009] As a preferred technical solution of the present application, an inclined groove is formed inside the nut, and a pressing groove is formed on the outer wall of the ferrule. The inclined groove cooperates with the pressing groove.

[0010] As a preferred technical solution of the present application, the locking member includes a screw rod threadedly connected to the inner wall of the mounting ring. There are two groups of the screw rods symmetrically arranged about the central axis of the mounting ring. A locking plate is connected to the outer wall of the screw rod, and a retaining ring is fixedly connected to the outer wall of the screw rod.

[0011] As a preferred technical solution of the present application, a steel pipe is connected inside the ferrule. The retaining ring cooperates with the locking plate, and the locking plate cooperates with the nut.

[0012] In the solution of the present application:

[0013] After rotating the nut to compress the ferrule, the steel pipe is fixed by the ferrule, and then the screw rod is rotated. The locking plate is driven by the screw rod to fix the nut, so as to further improve the fixing effect on the nut, and solve the problems in the prior art that the current connection methods in the market mainly adopt thread and welding forms, and these methods often have complexity and insufficient sealing performance during the installation process.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0022] As Figure 1-3 shown, a ferrule joint applied to a flowmeter proposed in this embodiment includes a joint body 100. A threaded ring 101 is fixedly connected to the outer wall of the joint body 100. A first thread groove 102 is provided on the outer wall of the threaded ring 101. An installation ring 103 is fixedly connected to the outer wall of the joint body 100. A ferrule 104 is fixedly connected to the side wall of the installation ring 103. A locking component is connected to the side wall of the installation ring 103. Since the ferrule 104 is made of a flexible material, the sealing performance of the steel pipe 123 can be further improved.

[0023] As Figure 1-4 shown, as a preferred embodiment, on the basis of the above, further, a second thread groove 110 is provided on the outer wall of the installation ring 103. A nut 111 is threadedly connected to the outer wall of the installation ring 103 through the second thread groove 110. By providing the second thread groove 110, the position of the nut 111 can be adjusted, and the use effect is better.

[0024] As Figure 1-5 shown, as a preferred embodiment, on the basis of the above, further, an inclined groove 112 is provided inside the nut 111, and a pressing groove 113 is provided on the outer wall of the ferrule 104. The inclined groove 112 cooperates with the pressing groove 113. By providing the cooperation between the inclined groove 112 and the pressing groove 113, the ferrule 104 can be deformed, and the practicability is stronger.

[0025] As Figure 1-3 shown, as a preferred embodiment, on the basis of the above, further, the locking component includes a screw rod 120 threadedly connected to the inner wall of the installation ring 103. Two groups of screw rods 120 are symmetrically arranged about the central axis of the installation ring 103. A locking plate 121 is connected to the outer wall of the screw rod 120, and a retaining ring 122 is fixedly connected to the outer wall of the screw rod 120. By the action of the locking plate 121, it is convenient to further improve the stability of the nut 111.

[0026] As Figure 1-5 shown, as a preferred embodiment, on the basis of the above, further, a steel pipe 123 is connected inside the ferrule 104. The retaining ring 122 cooperates with the locking plate 121, and the locking plate 121 cooperates with the nut 111. By providing the retaining ring 122, it can better drive the locking plate 121 to move, making it more convenient to use.

[0027] Specifically, when the device is in use: First, insert the steel pipe 123 into the inner part of the ferrule 104, and then rotate the nut 111. Through the contact between the inclined groove 112 on the nut 111 and the pressure groove 113, the ferrule 104 is tightened. By contacting the ferrule 104 with the steel pipe 123, the fixation and sealing of the steel pipe 123 are achieved. Then, turn the screw rod 120 out of the inner part of the mounting ring 103. Under the action of the retaining ring 122, the locking plate 121 can be driven to move. After adjusting the locking plate 121 to a suitable position, continue to rotate the screw rod 120. After the locking plate 121 contacts the nut 111, the fixation of the nut 111 can be achieved, which is beneficial to improving the stability of the nut 111 after installation. Then, under the action of the first thread groove 102 on the thread ring 101, the flowmeter can be fixed, and the use effect is better.
