[0025] By providing a clamp-connection type valve in the embodiments of this application, the technical problems in the prior art that it is difficult to maintain and replace the valve welded on the pipeline and stress concentration is likely to occur at the welding point are solved.

[0026] The general idea of the technical solutions in the embodiments of this application to solve the above technical problems is as follows:

[0027] As Figure 1 、 Figure 2 shown, this application provides a clamp 3 - connection type valve, including a valve body 1. The valve body 1 is installed on a pipeline 2. A clamp 3 is detachably and fixedly arranged on the pipeline 2. An installation ring 4 is integrally formed on the outer circle of the valve body 1. The clamp 3 and the installation ring 4 are detachably and fixedly connected.

[0028] The clamp 3 is installed on the pipeline 2, and the valve body 1 is detachably and fixedly connected to the clamp 3 through the installation ring 4, realizing the quick disassembly and assembly of the valve, and no stress concentration will be generated, and the work is more stable.

[0029] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0030] Preferably, the clamp 3 and the installation ring 4 are fixedly connected by bolts. During the installation process, the installation ring 4 of the valve body 1 and the clamp 3 are aligned, and then fixed by bolts, so that the valve body 1 is installed on the pipeline 2.

[0031] Furthermore, an annular clamping ring 5 is arranged on the pipeline 2. The clamping ring 5 is integrally formed with the pipeline 2. The clamp 3 and the clamping ring 5 are detachably and fixedly connected.

[0032] Specifically, the clamping ring 5 is located at the end of the pipeline 2. An annular notch 6 is arranged on the end face of the clamp 3. The clamping ring 5 can be operably placed into the annular notch 6. The clamp 3 is limited by the cooperation of the clamping ring 5 and the annular notch 6, so that the end face of the clamp 3 cooperates with the installation ring 4. After the clamp 3 and the installation ring 4 are fixed, the clamp 3 is fixed on the pipeline 2.

[0033] Optionally, the clamp 3 and the snap ring 5 are fixedly connected by bolts. First, the clamp 3 is sleeved on the pipeline 2, then the clamp 3 and the snap ring 5 are fixedly connected by bolts, and finally the clamp 3 and the mounting ring 4 are connected by bolts to realize the fixation of the clamp 3 and the pipeline 2, and the fixation of the clamp 3 and the valve body 1.

[0034] Optionally, as Figure 2 shown, the clamp 3 is a complete ring structure, and the clamp 3 is sleeved on the pipeline 2;

[0035] Or,

[0036] as Figure 1 shown, the clamp 3 is composed of two half-ring structures and is fixedly connected by bolts. During the installation process, first, the mounting ring 4 and the pipeline 2 are butted, then the two parts of the clamp 3 are locked on the snap ring 5, and finally the clamp 3 and the mounting ring 4 are fixed.

[0037] Preferably, as Figure 2 、 Figure 3 shown, a seal 7 is arranged between the clamp 3 and the mounting ring 4. The seal 7 includes a gasket 71 and a seal ring 72. The outer side wall of the gasket 71 is integrally formed with the inner side wall of the seal ring 72. Annular grooves 8 are arranged on the end faces of the clamp 3 and the mounting ring 4. The gasket 71 is arranged between the clamp 3 and the mounting ring 4, and the two ends of the seal ring 72 are respectively inserted into the corresponding annular grooves 8.

[0038] During the installation process, the port of the seal ring 72 is inserted into the corresponding annular groove 8, and then the clamp 3 and the mounting ring 4 clamp the gasket 71. The setting of the sealing ring increases the axial sealing area and makes the sealing effect between the clamp 3 and the mounting ring 4 better.
