The copper oxygen shut-off valve is made of copper and is mainly used for oxygen pipes. The oxygen shut-off valve is divided into an external thread type and an internal thread type according to the position of the stem thread. According to the flow direction of the medium, there are straight-through, direct-current and angular. The shut-off valve is divided into seals, with a packing seal shut-off valve and a bellows seal shut-off valve.
Copper oxygen shut-off valve features:
1. Anti-combustion and fire resistance: The main components are made of copper alloy, which is a non-combustible material. Even if it collides with solid particles in high-speed airflow, it will not produce sparks;
2, safe and reliable: with dustproof, waterproof, anti-oil device, all the valve parts in contact with oxygen have undergone strict degreasing and oil-free measures before assembly, the filler material is PTFE, which ensures safe and reliable use;
3. Flexible opening and closing: Two structures are adopted according to the size of the diameter. The small diameter is an ordinary structure, and the internal path is increased by a large diameter to balance the pressure difference between the front of the valve and the valve to reduce the flexibility of opening and closing.
Design features of copper oxygen shut-off valve:
1. The valve is mainly composed of a valve body, a valve cover, a valve flap and the like;
2, spherical valve body, even force;
3, the direction of airflow, DN100 valve adopts the way of going in and out, ≥ DN100 valve adopts the up and down mode;
4. The operation mode of the copper oxygen shut-off valve is manual operation, the hand wheel is rotated clockwise, the valve is closed; the hand wheel is rotated counterclockwise, and the valve is opened;
5, ≥ DN100 valve added a pair of internal balancing device valve flap, ≥ DN250 external bypass valve.
Glass bits have a spade-shaped carbide point, used to drill holes in materials of glass, ceramics,etc. They generate high temperatures and have a very short life. Holes are generally drilled at low speed with a succession of increasing bit sizes. Diamond drill bits can also be used to cut holes in glass, and last much longer.
It is an alloy triangular bit mounted on the ordinary Electric Hand Drill, which has high hardness, sharp blade and good precision, and is specially used for opening holes in ceramic tiles. But the drill wears too much into concrete to be used on concrete.
