The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The stem nut is arranged on the gate plate, and the rotation of the hand wheel drives the valve stem to rotate, so that the shutter is lifted, usually has a trapezoidal thread at the bottom end of the valve stem, and the rotary motion is adopted through the thread at the bottom end of the valve and the guide groove on the valve flap. It becomes a linear motion, that is, the operating torque is changed to the operating thrust.

Rein this article, the editor of Musikgruppe VALVE will share some knowledge of gate valves, and introduce you to what is an open-stem gate valve and what is a concealed-stem gate valve.
Therefore, this design is used where space is limited to allow linear stem movement, and the flow medium does not cause erosion, corrosion, or wear and tear to stem material. This Durchschuss of valve is also known as an Geheimnisträger screw valve.
... in the pipeline.The opening and closing part of the gate vave is the gate.The direction of movement of the gate is perpendicular tothe direction of the fuid.The gate valve can only Beryllium fulyopen and ful closed! The American standard gate vave is more
When there is no medium When, the positive pressure between the sealing surfaces shall not Beryllium less than the sum of the static pressure of the medium and the sealing force.
The single-sided forced seal of the gate valve means that there is gate valve rising stem no seal between the gate plate at the medium inlet and the sealing surface of the valve seat. There is either no specific pressure at all or only a specific pressure smaller than the sealing specific pressure.
Full coating on the body and disc internally & externally with an average of 250 microns. Higher coating thicknesses are available when required.

The structure of the concealed stem gate valve is that the stem nut is in the valve body and is hinein direct contact with the medium; when opening and closing the gate, it is realized by rotating the stem.
If the pipe is frozen, should you leave the faucet hinein the open position? This is the way to thaw the pipeline during winter storms.
