Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon steel ball valve technology, specifically a carbon steel ball valve with easily replaceable connectors. Background Technology
[0002] Carbon steel ball valves play an important role in pipeline systems. Their plug body is a ball, and the valve can be opened or closed by rotating it 90 degrees. They are characterized by simple structure, convenient operation, and reliable sealing. They are suitable for a variety of media, such as water, solvents, acids, and natural gas, and are widely used in many fields such as chemical, petrochemical, petroleum, mining, and power.
[0003] Carbon steel ball valves are often installed in gas pipelines to ensure normal operation and safety control. However, when installing joints on carbon steel ball valves, it is necessary to make the carbon steel ball valve and the pipeline joint coaxial, control the parallel sealing surfaces of the two flanges, and ensure that the bolts on the flanges are tightened symmetrically, sequentially, and evenly. These installation requirements make it relatively laborious to install or disassemble the joints, thus affecting the efficiency of replacing joints on carbon steel ball valves. Therefore, a carbon steel ball valve that facilitates joint replacement is proposed. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carbon steel ball valve with easy-to-replace connectors.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon steel ball valve with easily replaceable connectors, comprising a carbon steel ball valve body and a pipe connector, and further comprising:
[0006] Assembly components, which are mounted on the carbon steel ball valve body, are used for assembling and disassembling pipe joints;
[0007] The assembly component includes a fastener, which is installed at one end of the carbon steel ball valve body, and the outer surface of the fastener is provided with threads.
[0008] As described above, a rubber pad is fitted on the outer surface of the fastener, and the rubber pad is located between the fastener and the pipe joint.
[0009] As described above, the pipe joint is fixed to the fastener with a threaded connection.
[0010] As mentioned above, one end of the pipe joint is in contact with the rubber gasket by compression.
[0011] As mentioned above, the pipe fittings are available in different specifications and are compatible with the threads.
[0012] Compared with existing technologies, this carbon steel ball valve with easy-to-replace fittings has the following advantages:
[0013] I. This utility model, through the cooperation between the pipe joint and the thread, compared with the assembly method using a flange, only requires tightening the pipe joint, which makes it easy to fix the pipe joint to the outer surface of the fixing component, and thus easy to assemble or disassemble it with the carbon steel ball valve body, thus facilitating the replacement of the pipe joint.
[0014] Second, this utility model uses a rubber pad fitted on the outer surface of the fastener, and through the cooperation between the rubber pad and the fastener and the pipe joint, when the pipe joint is tightened, the fastener and the pipe joint will compress the rubber pad, thereby sealing the assembly position of the fastener and the pipe joint through the rubber pad and ensuring its airtightness.
[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-4 As shown, this utility model provides a carbon steel ball valve with easy-to-replace connectors, including a carbon steel ball valve body 1 and a pipe connector 3, and further including:
[0023] Assembly components, which are mounted on the carbon steel ball valve body 1, are used for disassembling and assembling the pipe joint 3;
[0024] The assembly component includes a fastener 2, which is installed at one end of the carbon steel ball valve body 1, and the outer surface of the fastener 2 is provided with threads 4.
[0025] Because the pipe joint 3 is designed to be compatible with the thread 4, there is no need to calibrate its position. This makes it easy to fix the pipe joint 3 to the outer surface of the fastener 2, which in turn makes it easy to assemble or disassemble it with the carbon steel ball valve body 1. Therefore, it is easy to replace the pipe joint 3.
[0026] like Figure 2 , 3 As shown in Figures 4 and 5, a rubber pad 5 is fitted on the outer surface of the fastener 2, and the rubber pad 5 is located between the fastener 2 and the pipe joint 3.
[0027] The rubber pad 5 and the fastener 2 cooperate to seal the assembly position of the fastener 2 and the pipe joint 3, ensuring their airtightness.
[0028] like Figure 1 , 2 As shown, the pipe joint 3 is fixed to the fastener 2 by the thread 4.
[0029] By engaging the pipe joint 3 with the thread 4, the pipe joint 3 can be fixed to the fastener 2, thereby completing the assembly of the carbon steel ball valve body 1.
[0030] like Figure 4 As shown, one end of the pipe joint 3 is in contact with the rubber pad 5 under pressure.
[0031] Through the cooperation between the pipe joint 3 and the rubber gasket 5, when the pipe joint 3 and the fastener 2 are assembled, the pipe joint 3 and the fastener 2 will compress the rubber gasket 5, thereby sealing the connection between the fastener 2 and the pipe joint 3.
[0032] like Figure 1 , 2 As shown, pipe fittings 3 are available in different specifications, and pipe fittings 3 are compatible with threads 4.
[0033] By designing the pipe fitting 3, different specifications of pipe fittings 3 can be assembled on the carbon steel ball valve body 1, enabling it to adapt to different scenarios and expanding its application range.
[0034] Working principle:
[0035] Through the engagement between the pipe joint 3 and the thread 4, the operator can rotate the pipe joint 3 to fix it on the outer surface of the fastener 2, which facilitates the assembly and disassembly of the pipe joint 3. At the same time, when installing the pipe joint 3, the rubber gasket 5 fitted on the outer surface of the fastener 2, and the engagement between the rubber gasket 5 and the fastener 2 and the pipe joint 3, will compress the fastener 2 and the pipe joint 3 when the pipe joint 3 is tightened, thereby sealing the assembly position of the fastener 2 and the pipe joint 3 through the rubber gasket 5, ensuring its airtightness.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
