F43X manual sector glasses valve, also known as blind valve, flap valve, fan valve, GB6222 "Industrial Gas Safety Regulations" requirements of reliable cutting off gas media equipment. Widely used in industrial and mining enterprises, municipal, environmental protection and other industries in the gas medium management system, especially for harmful, toxic, flammable gas absolute cut off. It is also suitable for blind terminal of pipeline terminal, so as to shorten maintenance time or facilitate the connection of new pipelines.
Compared with other valve equipments which do absolute cut-off in pipeline, this series of fan-shaped spectacle valve has the characteristics of novel structure, light weight, small volume, convenient operation, quick action and absolute reliability of cutting-off gas performance.
Characteristics and working principle
F43X manual sector glasses valve consists of left valve body, right valve body, middle valve body and connecting screw rod (San Gen). The screw is rotated by a wrench to make the left and right valve bodies clamp and loosen, and the opening and closing purposes are achieved by changing the position of the blind plate and the through-hole plate on the gate plate. The valve has the characteristics of simple structure, light weight, reliable performance and convenient operation. This valve is a short series, rubber sealing rings are respectively arranged on the left and the right valve body.

Installation notes
When the manual sector valve is opened, the left and right valve body should have 16-20mm axial displacement. Therefore, the pipeline should also have the elastic deformation or displacement to meet the above displacement in the process of valve opening and closing. It is recommended to install the pipeline in the following form. The installation position of the fan-shaped glasses valve is not prescribed under the condition that the external force of the pipe does not act on the valve.
Operation methods and matters needing attention
1. Use the wrench to turn three connecting screw counterclockwise in turn, so that the valve body and the gate are separated and balanced, with an appropriate amount of clearance (about 16 mm). After confirmation, the gate is rotated to the working position, and the screw is connected by reverse rotation, so that the gate is in close contact with the valve body to achieve the purpose of absolute sealing.
2. The rubber sealing ring must not be adhered to the valve body or hard friction, in order to prevent damage to the rubber sealing ring, damaging the working performance of the valve.
3. When the left and right valve bodies are loosened, the medium will overflow. To ensure safety, the gas butterfly valve in front of the glasses valve should be closed, and ventilation and other measures should be taken to ensure safety.
4, F43X and F43AX manual sector glasses valve in the opening of the left and right valve body, should pay attention to the gate will automatically fall down, the operation is prohibited to stand on the front of the gate, in order to avoid danger.
