A control valve based on flange connection

Abstract

The invention relates to a control valve based on flange connection. The control valve comprises a flange, a locking assembly, a protection assembly and a valve body. The locking assembly is connectedto the left side inside the flange, the protection assembly is connected to the right side inside the flange, the valve body is communicated with the right side of the flange, the locking assembly comprises a connecting pipe installed at the right end face of the left side plate, the left end of the connecting pipe is of a cone frustum structure, the left side of the side wall of the connecting pipe is evenly provided with locking grooves in the peripheral direction, and locking rods are installed inside the locking grooves through locking springs. The problems that when an existing valve isconnected with a pipeline, clamping is adopted, disassembling is not convenient, the sealing performance is poor, and rotation and water leakage are likely to be caused, when flange connection is adopted, the sealing performance is poor, when the existing valve is connected with the pipeline, the single connection mode is adopted mostly, and the defects caused by the single connection mode cannotbe avoided are solved. The rapid and diversified connection functions of the valve and the pipeline can be achieved; and the control valve has the advantages that disassembling is convenient, fixationis firm, the sealing performance is good, and connection modes are diversified.

Description

technical field [0001] The invention relates to the field of valves, in particular to a control valve based on flange connection. Background technique [0002] Valves are generally important control switches during pipeline transportation. When using valves, it is necessary to ensure that the valves are connected to pipelines. Existing valves and pipelines usually have snap connections, screw connections, flange connections, etc., and different connection methods have their own characteristics. Advantages and disadvantages, however, there are many problems in the specific connection: [0003] Problem 1: It is convenient to use the card connection, but it is inconvenient to disassemble. At the same time, the card connection is easy to rotate and leak, and its sealing performance is poor; [0004] Problem 2: The flange connection is firmly fixed, and there is also the problem of poor sealing. At the same time, most of the existing valves and water pipes are connected by a sin...

AI Technical Summary

Problems solved by technology

[0003] Problem 1: It is convenient to connect when using snap-in, but it is inconvenient to disassemble. At the same time, the snap-in is easy to rotate and leak, and its sealing performance is poor;

[0004] Problem 2: The flange connection is firmly fixed, and there is also the problem of poor sealing. At the same time, most of the existing valves and water pipes use a single connection method, which cannot effectively avoid its shortcomings

[0005] For the problems listed above, there is no better exploration and practice results under the existing technical conditions. Therefore, it is necessary to do further exploration and practice to solve the problems listed above
