The double jacket gate valve is a specially designed valve with a dual-layer jacket structure, consisting of an inner and an outer jacket. This design is primarily aimed at providing precise temperature control of the internal fluid within the valve, making it suitable for operations in extreme temperature environments. The following is an introduction to the double jacket gate valve.

Structure

Inner jacket: mainly used to control the inner layer of fluid flow.

Outer Jacket: The outer jacket is a layer located outside the inner jacket, and its main function is to provide additional insulation or cooling. Through the outer jacket, a thermal carrier or cooling medium can be introduced to influence the temperature of the environment surrounding the valve.

Application scenarios

1. High-Temperature Applications: Double jacket gate valves are suitable for situations that require operation in high-temperature environments. The outer jacket can maintain the temperature around the valve by introducing a cooling medium, ensuring that the fluid inside the inner jacket operates at an appropriate temperature.

2. Low-Temperature Applications: They can also be used in low-temperature environments by introducing a thermal carrier into the outer jacket to provide insulation, preventing the freezing of the valve structure.

Temperature control

The double jacket structure allows the adjustment of the temperature in the vicinity of the valve by introducing heating or cooling media into the outer jacket, ensuring that the fluid inside the inner jacket operates within an appropriate temperature range.

Industry applications

In industrial sectors such as chemical, petroleum, and natural gas industries, the double jacket gate valve is widely employed, particularly in complex processes that require temperature control of fluids. In certain laboratory or production environments where precise control of fluids is necessary, double jacket gate valves may also be utilized.

Anti-freeze insulation

In cold environments, the design of the outer jacket can also be utilized to prevent the freezing of the valve structure, ensuring the normal operation of the valve.

Overall, the double jacket gate valve, through its unique structural design, provides a stable working environment for fluids under different temperature conditions. It is suitable for industrial and experimental scenarios where higher temperature control requirements are needed.
