Flue gas gate slide damper satinless steel low pressure middle temperature
Product description
There are three types of plug-in valves: manual plug-in valves, electric plug-in valves, and pneumatic plug-in valves. Manual plug-in valves are also called manual screw gate valves.Manual plug-in valve, also known as manual knife-type gate valve, knife-shaped gate valve is a kind of valve that the gate and the valve seat are always in close contact and seal. The principle is that the gate board has a diameter-sized round opening and is opened by the gate. Closing makes the round hole on the ram plate completely separate from and coincide with the diameter.

Feature
Widely used in metallurgy, mining, building materials, food, manual spiral gate diameter and UN-loader feed port matching; there are two kinds of square and round.
The advantage of this valve is that there is no groove in the valve body, and the medium does not block and block, and it has full-diameter flow characteristics, which is suitable for use in the pipeline of powder and granular media.
The plug door seal structure can be divided into soft seal and hard seal structure. With features such as good workmanship and compact structure, the sealed valve seat is designed as a movable structure and has the functions of anti-wear and automatic compensation, and thus has a longer life. During the closing and opening process of the inserting plate door, the valve seat and the gate plate are always in close contact with each other, so that the valve opening and closing force is stable and has the characteristics of cutting off the medium.
Configure the hand wheel to operate the hand wheel directly to open and close the valve.
Installation
1. Before installation, check the inside of the valve chamber and the sealing surface, and do not allow any dirt or sand particles to adhere;
2. The bolts at each connecting point require uniform tightening;
3. Check that the packing area is pressed tightly to ensure not only the packing's tightness, but also the flap's opening flexibility;
4. Before the user installs the valve, the model of the valve must be calibrated, the connection size and the direction of the medium should be observed to ensure consistency with the valve requirements.
5. The user must reserve the necessary space for valve actuation when installing the valve.
6. The wiring of the driving device must be carried out according to the wiring diagram;
7. The flapper valve must be maintained regularly and must not be crushed and squeezed so as not to affect the seal.
