Product Name: Electric Valve Model: Z941H, MZ941H, Z941W, Z941Y drive: electric, manual connection type: flanges, welded structural forms: wedge seal structure: hard seal, soft seal pressure range: 1.6MPa-16.0MPa Nominal Diameter: DN15-600 common material: WCB, stainless steel, alloy steel plate: male workers brand products described ordering process electric valve, explosion-proof electric valve, explosion-proof electric valve is simply the electric control valve actuators, thereby realization of the valve opening and closing. It can be divided into two parts, the upper part of electric actuators, valve actuation torque than the lower half into a large electric valve, electric valve switching speed can be adjusted, simple structure, easy maintenance, the course of action because of the gas itself cushioning properties, not easy to get stuck due to damage, but there must be gas source, and its control system is also more complex than an electric valve. Electric valve response sensitive, safe and reliable. MZ941H series of mine convenient electric gate installation, commissioning and simple, a few years after commissioning without maintenance, flameproof electrical equipment and KXBC-3 × 15/660 (380) DZ or KXBC After -15/660 (380) DZ supporting the use of the interface with the DCS system. Mine explosion-proof electric gate protection class: IP68, is one of the few companies have only coal mine safety certificate and proof certificate. Mine explosion-proof electric valve for coal occasions, high safety factor, operating functions, stable performance. Explosion-proof products dI and dIIBT4 two kinds, dI for coal mining face non; dIIBT4 used in factories for the environment IIA, IIB grade gas mixture T1 ~ T4 group. Electric valve, perform standard design specifications: GB / T 12234 length of the structure: GB / T 12221 Flange: JB / T 79 test and inspection: JB / T 9092 Pressure - Temperature: GB / T 9131 Product Identification: GB / T 12220 gate valve opening and closing parts is, the direction of movement of the fluid direction perpendicular to the gate, gate can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high for 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate board called the flexible gate. When the valve is closed, the sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Gate valve with the valve stem linear movement, called the lift rod valve also called clear shot valve. Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to the diameter of the 1: 1 times, the fluid channel is completely smooth, but at run time, this position is not monitored. Actual use, is the apex of the stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the position of the valve fully open. Therefore, the fully open position of the valve, according to the position of the gate is determined that the stroke. Some valve stem nut located at the gate, handwheel drive stem rotation, leaving the gate to upgrade, this valve is called the rotating rod valve or valve called the dark bar. Valve closure member Principle (ram) movement do fully open and fully closed off with a vertical path along the centerline. Valve selection Gate Valve is mainly used to cut off or turn on the line of medium, is generally not as a regulator or throttling. Category gate valve can be divided according to different classification methods: parallel gate valve, wedge gate valve, lift gate, rotary valve rod, fast opening and closing valve, necking valve, flat gate valve and so on. Valve fluid resistance characteristics, the applicable pressure, high temperature range, medium flow unrestricted, good sealing performance. Contact Shanghai-Valve Co., Ltd.
