Gate valve application instructions
Gate valve opening and closing pieces is the gate, the direction of movement of the gate and fluid perpendicular to the gate valve can only be fully open and fully closed, can not be adjusted and throttling. Applicable medium: water, oil, gas, steam, acids. Manufacturing standards: GB, American Standard, Japanese standard, German standard. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves form a wedge. The wedge angle varies from valve to valve, typically 50, with a 2 ° 52 'medium temperature. Wedge gate valve gate can be made as a whole, called the rigid gate; can also be made to produce a slight deformation of the gate, to improve its technology to make up for sealing surface angle in the process of deviation, this gate The board is called a flexible gate. Gate valve type, according to the sealing surface 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 For the single gate and double gate type. According to the thread position of the stem division, can be divided into Ming rod valve and dark rod gate valve two. Gate valve is closed, the sealing surface can only rely on media pressure to seal, that is, rely on media pressure gate, valve diameter DN15-DN600. Connection: flange, welding, internal thread. Transmission: Manual, spur gear, bevel gear, pneumatic, electric. Applicable medium: water, oil, gas, steam, acids. Manufacturing standards: GB, American Standard, Japanese standard, German standard.

Gate valve type, according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve gate wedge gate valve can be divided into: single gate type, double gate type and elastic gate type; parallel gate type gate valve can be divided into Single gate and double gate type. According to the thread position of the stem division, can be divided into Ming rod valve and dark rod gate valve two. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal.
