LQ-GXF High-temperature pressure relief valve
LQ-GXF High-temperature pressure relief valve

LQ-GXF High-temperature pressure relief valve

Purpose Mainly used for proportional ventilation of high-temperature flue gas. lt is widely used in places where leak rate requirements are not high, such as RTO and other high-temperature smoke direct discharge places. It is mainly composed of a butterfly valve body and a matching pneumatic actuator (GT/RT/AT/AW series), which can be used for switch control or flow regulation of low-pressure pipeline media. The butterfly valve adopts a new structural form of a center line butterfly plate and a short structure steel plate welding with a compact structure, light weight, easy installation, small flow resistance, large flow capacity, and avoids the influence of high-temperature expansion, making it easy to operate. lt can be installed in multiple positions without being affected by the flow direction of the medium. Powered by compressed air, the valve stem drives the circular disc butterfly plate to rotate around the axis to control the flow. The valve completes one action (from open to close or from close to open) after rotating 90°from the initial position. The opposite completes the other action (from close to open or from open to close).

    Notes:

    1. Cannot be used in corrosive, viscous, or particle dust fluid environments

    2. Explosive-proof places require overall explosion-proof treatment.

    Purpose

    Mainly used in applications that require frequent movement and high sealing requirements, such as the inlet and outlet valves of large air volume three or multi-chamber RTOs. lt is mainly composed of a butterfly valve body and a matching pneumatic actuator, which can be used to switch and control low-pressure pipeline media.

    The double connecting rod is used to connect the butterfly valve disc and the eccentric shaft, and the back is fixed with a connecting rod to limit the valve disc stroke. This eccentric structure greatly improves the sealing of the valve.

    Powered by compressed air, the eccentric shaft is driven to control the connecting rod's switching of the valve disc. After the valve is rotated 90°from the initial position, one action is completed (from open to close, or from close to open), and vice versa for the other action (from close to open, or from open to close).

    Structural Form

    Features

    1. Eccentric shaft, low leakage rate.

    2. Pneumatic drive, flexible operation, short travel time, low noise.

    3. It has a simple structure, easy maintenance and quick switching, and can be used to increase work efficiency and reduce maintenance time, as well as to select different materials for seal rings depending on customer requirements.

    Caution:

    1. It cannot be used in corrosive, sticky, granular dust fluid places.

    2. Explosive-proof places require a full blast-proof treatment.
