Factory direct supply sufficient iron bar gate dark dark bar wedge gate valve professional quality

Brand: Southbridge Valve Model: Z45H Connection: Flange material: steel nominal diameter: 100mm Temperature: Range 300 Application: aquatic Alias: rotating rod valve, dark bar wedge gate valve body materials: steel pressure range: 16Mpa Medium: steam pressure environment: atmospheric temperature: room temperature Standard: GB appearance: miniature flow direction: one-way drive: electric parts and accessories: a sphere shape: duckbill type (channel position): Straight-dark bar 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. Dark bar called the rotating rod gate valve (also called dark bar wedge gate valve). Stem nut located at the gate, handwheel drive stem rotation, leaving the gate to upgrade, usually at the bottom of the valve stem with trapezoidal thread, and the thread through the valve at the bottom of the valve guides 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 to 1 lap, as the position of the valve fully open. Therefore, the fully open position of the valve, according to gate position (ie, stroke) to determine. Dark rod valve stem gate valve with distinction: 1. dark bar valve stem when the switch is connected with the steering wheel and relatively immobile, it is through the stem at a fixed point of rotation to drive the valve lifts up and down the gate to complete opening and closing. Rising stem valves are used to raise or lower the valve stem and the steering wheel through the threaded drive. Simple point is that the next shot valve is attached to the valve stem up and down movement together, the steering wheel has a fixed point; 2. dark bar screw flange valve lift is only rotated up and down without moving, exposed just a rod, a nut which is fixed to the gate, through the rotation of the screw to enhance the gate, no visible door frame; rising stem gate valve flange lifting screw is exposed, the nut against the hand wheel and is fixed (does not rotate nor axial movement), to enhance the gate, and the gate of the screw only relative rotational movement by turning the screw without relative axial displacement, the appearance of a door-shaped bracket; 3. dark bar valve is invisible screw, The next shot is to be able to see the screw.
