Production introduction

Discharging valves are mainly used for bottom discharging, discharging, sampling and dead-zone-free shut-off operations of reactors, storage tanks and other vessels. With the help of the bottom flange of the valve, it is welded to the bottom of storage tanks and other vessels, thus eliminating the residual phenomenon of process medium usually at the outlet of the vessels. According to the needs of the actual situation, the bottom structure of the discharge valve is designed as a flat bottom type, the valve body is Y-shaped, and the valve disc is provided with two working modes: lifting and descending.
The sealing pair adopts line sealing, and the valve disc seal can be overlayed with hard alloy as needed to make the surface hardness reach HRC56~62. It has high wear resistance and corrosion resistance, ensuring the reliability of the seal.

Product characteristic

Controllable discharging: It can accurately control the discharging amount, realize quantitative and fixed-speed discharging, and meet the process requirements.
The flow channel of the valve body is smooth: the Y-shaped valve body does not block or block when discharging materials, and large flow can flow.
High temperature resistance and corrosion resistance: The sealing pair can be overlayed with hard alloy to protect it from erosion, wear and corrosion.
Simple and reliable structure: The structure is simple and practical, with few parts. The moving parts are the linear motion of the valve plate. It has high reliability, long service life and easy maintenance.
Wide range of connection methods: arc flanges, flat flanges, welding installation, etc. can be customized according to actual customer needs.
Optimized packing group design: double-layer packing design provides sustainable and effective sealing and extends service life.

Differences between up/down expanding discharge valve

Differences in applicability:
The upward type is used for reactors with agitators.
The downward type discharge valve is used for reactors with frame anchor type stirrers.

The difference between the opening and closing torque:
The upward type needs to overcome the force of the medium. When opening, the torque is larger than that of closing.
The downward type complies with the thrust of the medium. When opening, the torque is smaller than that of closing.
