Description

[Technical field]

[0001] The utility model relates to the technical field of C-type ball valves, in particular to a C-type ball valve with an automatic temperature adjustment function. [Background technology]

[0002] When the C-type ball valve is used for media with poor fluidity at room temperature, due to the slow flow rate of the medium, part of the medium flowing through the valve body will adhere to the sealing surface, making the valve difficult to open and close, and may cause sealing failure. In addition, since the middle cavity structure is relatively closed, the long-term accumulation of adhered solid particles can easily cause the middle cavity to be blocked and stuck. Therefore, it is necessary to consider raising the temperature state of the medium to make its fluidity good. In addition, when the C-type ball valve is used in high-temperature conditions, due to long-term operation in a high-temperature environment, the C-type ball valve is prone to problems such as thermal expansion deformation, aging of sealing materials, and degradation of metal materials.

It is equipped with two steam input devices, which use the heat of hot steam to purge and heat the spherical surface and back of the ball respectively. However, this design is limited to increasing the ambient temperature of the ball valve and cannot solve the problem of needing to reduce the working temperature of the ball valve. It has certain limitations. In addition, the operation process of this design requires manual control, which is not very convenient. [Utility Model Content]
