Product Description



The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedges and wedge angles that vary with the parameters of the valve, usually 5 degrees and 2 52'when the medium is not high. The opening and closing parts of gate valves are gate plates, and the movement direction of the gate plates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and closed, and can not be adjusted or throttled. The sluice gate of a wedge valve can be made into a whole, called a rigid gate, or a sluice which can produce a small amount of deformation to improve its craft and make up for the deviation produced by the angle of the sealing surface in the process of processing, which is called an elastic gate. When the gate is closed, the sealing surface can be sealed only by the pressure of the medium, that is, the sealing surface of the gate is pressed to the seat of the other side by the pressure of the medium. This is self sealing. Most of the gate valves are forcibly sealed, that is, when the valve is closed, we must rely on external force to force the gate to the valve seat to ensure the sealing performance of the sealing surface. The gate of a gate valve moves linearly along with the stem. It is called the lifting rod gate valve, also known as the gate valve. Usually there are trapezoid threads on the lifting rod. Through the nut at the top of the valve and the guide slot on the valve body, the rotation motion is turned into a straight motion, that is, the operating torque is converted to the operating thrust. When the valve is opened, when the lift height of the gate is equal to 1:1 times of the valve diameter, the fluid passage is completely unblocked, but the position can not be monitored at the time of operation. The actual use is based on the vertex of the stem as a sign, that is, the location of the open position as its full open position. In order to take into account the locking of temperature changes, the 1/2-1 circle is usually returned to the vertex position as the position of the full open valve. Therefore, the full opening position of the valve is determined according to the location of the gate. Some gate valves, valve stem nuts on the gate, hand wheel rotation to drive the stem rotation, and make the gate lift, this valve is called the rotary bar valve, or the dark rod valve.
