Z41H cast steel flanged gate valve，Cast steel flanged gate valve，Flanged gate valve

The opening and closing part of the gate valve is the gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and it is not suitable for adjustment and throttle. The gate has two sealing surfaces. The two sealing surfaces of the most common wedge gate valve form a wedge, and the wedge Angle varies with the valve parameters, usually 5°. Wedge gate valve can be made into a whole, called rigid gate; Can also be made to produce micro-deformation of the ram, in order to improve its technology, make up for the Angle of the sealing surface in the process of processing the deviation, this ram is called elastic ram. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the other side of the valve seat to ensure the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on external force to force the gate to the valve seat to ensure the sealing surface of the seal. Gate valve with the valve stem together for linear motion, called lift rod gate valve (also called open rod gate valve). Usually, there are trapezoidal 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 changed to a straight line, that is, the operating torque is changed to the operating thrust. Some valves, the stem nut is located on the gate, the hand wheel rotation drive the stem rotation, and the gate lift, this kind of valve is called the rotary rod gate valve or the dark rod gate valve.

Two, Z41H cast steel flange gate valve - has the following advantages;

1. The fluid resistance is small, and the sealing surface is washed and eroded by the medium.

2. It takes less effort to open and close.

3. The flow direction of the medium is not limited, does not disturb the flow, does not reduce the pressure.

4. Simple shape, short structure length, good manufacturing technology, wide range of application. Type of gate valve: according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve can be divided into: single gate type, double gate type and elastic gate type; Parallel gate valve can be divided into single gate type and double gate type. According to the thread position of the valve stem, it can be divided into two types of gate valve and gate valve.

It can be respectively applied to various media such as water, steam, oil products, nitric acid, acetic acid, oxidizing media, urea, etc.
