First of all, the structural composition of the Angle valve includes the valve body, valve cover, valve core, valve stem, seat, sealing ring and other components. The valve body is the main part of the Angle valve, and the internal channel is provided for controlling the flow of fluid. The valve cover is installed on the valve body to seal and fix the spool. The spool is a key component of the Angle valve, which changes the opening and closing degree of the fluid channel by rotating or moving up and down. The stem is connected to the spool and is used to transfer the operating force to the spool so that it can realize the switching action. The seat is installed inside the valve body and plays a sealing role with the spool. The sealing ring is used to prevent fluid leakage and ensure the sealing performance of the valve.
Secondly, the working process of the Angle valve can be divided into two stages: opening and closing. When the Angle valve needs to be opened, the operator makes the spool rise by rotating the valve stem, the fluid channel gradually opens, and the fluid begins to flow. On the contrary, when the Angle valve needs to be closed, the operator rotates the valve stem again, so that the spool is lowered, the fluid channel is gradually closed, and the fluid stops flowing. In the entire working process, the sealing between the spool and the seat plays a key role, and their degree of tightness directly affects the sealing performance and fluid control ability of the Angle valve.
The working principle of the Angle valve can be simply summarized as: through the operation of the valve stem to control the movement of the valve core, so as to change the opening and closing degree of the fluid channel, to achieve the adjustment of the fluid flow. Angle valves are widely used in industrial production and daily life, and the understanding of their working principle is very important for the correct use and maintenance of Angle valves.
Angle valves are a common type of valve commonly used for fluid control and regulation in piping systems. Here are some common applications of Angle valves:
1. Household water pipe system: In the household water pipe system, the Angle valve is usually used to control and turn off the water source, such as to control the water supply of the faucet or water appliance in the toilet, kitchen, bathroom and other places. By rotating the Angle valve handle, the water flow can be easily opened or closed to achieve the control of water flow.
2. Hvac systems: In heating, ventilation and air conditioning systems, Angle valves are used to control and regulate the flow of hot or cold water to regulate the indoor temperature. By adjusting the opening degree of the Angle valve, the flow of hot or cold water can be controlled, so as to adjust the working effect of the indoor air conditioning system.
3. Industrial pipeline system: In the pipeline system in the industrial field, Angle valves are usually used to control the flow of various media, such as liquids, gases, etc. Angle valves can be opened, closed or adjusted as needed to meet the requirements of different processes.
4. Laboratory equipment: In laboratory equipment, Angle valves are usually used to control the flow of media in laboratory equipment, such as controlling the flow of water in laboratory sinks or controlling the flow of laboratory gas streams.
5. Agricultural irrigation system: In agricultural irrigation systems, Angle valves are used to control the flow and direction of water flow in irrigation pipes to achieve irrigation and drainage of farmland.
Material selection:
1. Copper: Copper is a commonly used Angle valve material, with good thermal conductivity and corrosion resistance, suitable for general household water pipe systems and HVAC systems.
2. Stainless steel: Stainless steel has excellent corrosion resistance and high temperature resistance, suitable for industrial piping systems requiring high strength and durability and applications in special environments.
3. Brass: Brass is a common Angle valve material, with good corrosion resistance and processing properties, suitable for household water pipe systems and general industrial pipe systems.
4. Cast iron: Cast iron Angle valve has high strength and wear resistance, suitable for some industrial applications requiring high strength and durability.
5, PVC (polyvinyl chloride) : PVC Angle valve has good corrosion resistance and wear resistance, suitable for some chemical, water treatment and sewage treatment and other fields.
6. Polypropylene (PP) : polypropylene Angle valve has good corrosion resistance and chemical stability, suitable for fluid control of some special media.
The production process of Angle valves usually includes the following steps:
1. Material preparation: According to the design requirements and customer needs, prepare the corresponding Angle valve materials, such as copper, stainless steel, brass, etc.
2. Cutting: The prepared material is cut according to the design requirements to make the various parts of the Angle valve, such as the valve body, valve cover, valve core, etc.
3. Forming: Through stamping, casting, forging and other processes, the cut parts are formed to ensure that they meet the design size and shape requirements.
4. Processing: Processing of the molded parts, including drilling, milling, turning and other processes to ensure the accuracy and surface quality of the parts.
5. Assembly: The processed parts are assembled, including the installation of spool, sealing ring, valve stem and other components, and assembled into a complete Angle valve structure.
6. Debugging: Debug the assembled Angle valve, check the opening, closing and sealing performance of the valve, and ensure the normal operation of the Angle valve.
7. Surface treatment: Diagonal valve surface treatment, such as spraying, coating, etc., to improve the corrosion resistance and beauty of the valve.
8. Inspection: Make a comprehensive inspection of the Angle valve, including appearance inspection, sealing performance test, pressure test, etc., to ensure that the Angle valve meets the relevant standards and requirements.
9. Packaging: the qualified Angle valve will be packaged, including identification, instructions, etc., for transportation and use.
Structural characteristics of Angle valve
Angle valve medium inlet and outlet channel is not in the same direction and into a 90 degree Angle (as shown in Figure 1), the medium through the Angle valve changes the flow direction, resulting in a certain pressure drop, its biggest advantage is that the Angle valve can be installed at the corner of the pipeline, both saving 90 degree elbow, and easy to operate, the medium flow and the valve stem on the same axis, so easy to seal.
Connection mode
The structure of the common Angle valve is shown in Figure 1, and the names of its various components are shown in Table 1. Angle valve connection mode welding and flange connection two, threaded connection Angle valve is not common.
