·Long neck valve cover design: Extend the neck of the valve cover to reduce the transmission of cold to the operating mechanism and prevent the packing from freezing. The neck length is calculated and determined based on factors such as the thermal conductivity and heat dissipation coefficient of the material, ensuring that the temperature at the bottom of the packing box remains above 0 ℃.
·Anti abnormal pressure rise structure: A pressure relief hole is installed on the inlet side of the gate plate. When the pressure in the valve chamber increases, gas can be discharged through the small hole to prevent the gate plate from tightly pressing the valve seat and causing it to fail to open.

Self-operated Temperature Regulator is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
RAYS Three-Way and Multi-Port Ball Valve are important components in fluid control systems and are widely used in various industrial fields. They are variants of ball valves. Their design allows fluids to be distributed or converted between more than two pipes. The three-way ball valve has three interfaces, which can realize the diversion, confluence or switching of fluids. According to the different internal structures, it is divided into L-type and T-type. The L-type can only connect two mutually orthogonal pipes, and cannot simultaneously maintain the interconnection of the third pipe, and only plays a distribution role; the T-type can make three orthogonal pipes interconnected and cut off the third channel, playing a diversion and confluence role. The multi-way ball valve is an extension of the three-way ball valve, with more interfaces and more complex fluid control functions.
The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
