Internal Thread Stop Valve

Internal thread stop valve is a common fluid control valve, widely used in water, gas, oil and other fluid pipeline systems, used to adjust the flow or completely cut off the flow. The main feature of the internal thread stop valve is the use of internal thread connection, which is simple and reliable, and is widely used in medium and low pressure pipeline systems.

Design and manufacturing: GB/T12224-2005 / JB/T7747-1995
Connection type: internal thread connection
Structural features: conical cover; movable valve disc
Valve inspection and testing: JB/T9092-1999

※ Main Features
Internal thread connection
The inlet and outlet pipe connection ends of the internal thread stop valve are designed with internal threads. The internal thread of the valve can be connected to the pipe with external thread, and the connection is made by rotating the pipe, which is easy to install and can save installation space. Compared with the external thread connection, the internal thread design has better sealing performance and is suitable for use in systems that require high sealing performance.
Valve body material
The valve body of the internal thread stop valve is usually made of cast steel, stainless steel, copper or brass, which has corrosion resistance, high temperature resistance, high pressure resistance and other properties, and is suitable for various working environments. Different material selections can be customized according to the fluid properties and working conditions to ensure the long-term stability of the valve.
Valve disc and valve seat
The valve disc and valve seat are the key components of the internal thread stop valve. The valve disc adopts a sealing design and can be in close contact with the valve seat when closed to ensure that the fluid will not leak. The valve disc is usually raised and lowered by rotating the valve stem to accurately control the size of the flow.
Operation method
The internal thread stop valve is usually manually operated, and the opening and closing of the valve are adjusted by rotating the handwheel or handle. It can also be equipped with an electric or pneumatic actuator for remote control.

※ Product Application
Home and building pipelines
Internal threaded stop valves are widely used in water supply and drainage pipeline systems. They can accurately adjust the water flow and ensure the stability and safety of the water pipe system. Its compact design is particularly suitable for use in environments with limited space.
Oil and gas industry
In oil and gas pipeline systems, internal threaded stop valves are used to control the flow of oil and gas. Due to its good sealing and high temperature and high pressure resistance, it is suitable for use in high-pressure pipelines of oil and gas.
Chemical industry
Internal threaded stop valves can effectively control the flow of chemical media and prevent the leakage of toxic and harmful substances. The fluid control requirements in the chemical industry are usually high, and internal threaded stop valves can provide precise flow regulation to meet the needs of various chemical production.
Food and pharmaceutical industry
In the pharmaceutical, food processing and other industries, internal threaded stop valves are used to finely control the flow of liquids and gases and ensure the hygiene requirements of the production process. The sealing and corrosion resistance of the valve ensure the stability of product quality.

※ FAQ

What are the installation requirements for control valves?
The valve should be installed at the appropriate position of the pipeline to ensure that the flow direction is consistent with the direction indicated by the valve body; secondly, check whether the valve and its accessories are intact before installation to ensure that there is no damage; during installation, ensure that the pipeline connection is stable to avoid stress concentration and prevent damage to the valve; in addition, sufficient space should be provided for the valve to facilitate adjustment, inspection and maintenance; finally, the valve should be protected from excessive vibration or temperature, especially under high pressure and high temperature environments.

What are the common applications of temperature and pressure reducers?
Temperature and pressure reducers are widely used in many fields. They are mainly used in steam systems to reduce high-pressure steam to appropriate pressure to ensure safe operation of equipment. They are commonly used in power, fertilizer, food processing and other industries. They are also used in oil and gas pipelines, chemical production, pharmaceutical plants, etc. to ensure stable pipeline pressure and avoid system overpressure or excessive temperature. In addition, reducers are also used in HVAC, metallurgy and other industries to adjust the temperature and pressure of the fluid in the system to ensure the smooth progress of the process.

How to maintain medium and high pressure valves?
When maintaining medium and high pressure valves, first check the wear of key components such as valve body, valve seat, sealing ring and valve stem regularly. Clean the valve to prevent impurities from blocking and affecting operation. Check the operating performance of the valve to ensure flexible opening and closing without sticking. Check the sealing to prevent leakage and replace the seals if necessary. For valves that operate at high pressure for a long time, it is recommended to perform functional tests regularly to ensure their reliability under high pressure environment. In addition, check the connection parts of the valve to avoid looseness or leakage caused by vibration or corrosion.
