Curb Stop Valve With Right-angled Body Gold / Brass Bronzed-red Color

demand / carton packaging

characteristic:
(1) The stop valve structure is simpler than the gate valve and is more convenient for manufacturing and maintenance.

(2) The secret cover is not easy to wear and scratch, and it is well sealed. There is no relative sliding between the disc and the body cover when it is opened and closed. Therefore, the wear and abrasion are not serious, the sealing performance is good, and the service life is long.

(3) When opening and closing, the valve travels small, so the height of the stop valve is smaller than the gate valve, but the structure length is longer than the gate valve.

(4) The opening and closing moment is large, the opening and closing are more laborious, and the opening and closing time principal.

(5) The fluid resistance is large, because the medium channel in the valve is more tortuous, the fluid resistance is large, and the power consumption is large.

(6) When the medium flow direction is known as the pressure PN ≤ 16MPa, the flow is generally used, and the medium flows upwards from the lower part of the disc; When the nominal pressure PN ≥ 20MPa, countercurrent is generally used, and the medium flows downstream from the disc to increase the seal energy. When used, the stop-valve medium can only flow in one direction and can not change the flow direction.

(7) The disc is frequently eroded when fully opened.
The stem axis of the cut-off valve is perpendicular to the seat cover. The stem opens or closes for a relatively short period and has a very reliable cutting action, making the valve suitable for use as a medium for cutting or regulating and throttle.

advantages:

1, simple structure, more convenient for manufacturing and maintenance.

2, small work trip, short opening and closing time.

3, good sealing, close cover between the small grinding force, longer life.

4.The structure of the cut-off valve body is straight-through, DC and right-angled. The straight-through type is the most common structure, but its fluid resistance is the largest. DC type fluid resistance is small, mostly used for fluids containing solid particles or large viscosity. The right-angled valve body is mostly forged and is suitable for cut-off valves with smaller pass-through and higher pressure.

5, in the opening and closing process, the friction of the close cover is smaller than the gate valve, and it is wearable.

6, usually only a secret cover, manufacturing process is good, easy to repair.
