Description
Technical field
The utility model relates to a kind of valve technology field, particularly relates to a kind of electric gate valve.
Background technique
Gate valve
closetime, sealing surface can only rely on pressure medium to seal, and namely only relies on pressure medium the sealing surface of flashboard to be pressed to the valve seat of opposite side to ensure the sealing of sealing surface, selfsealings that Here it is.Major part gate valve adopts forced seal, namely during valve closing, external force be relied on by force flashboard to be pressed to valve seat, to ensure
sealingthe sealing in face.Motion mode:
gate valveflashboard with valve rod moving linearly, be also Outside screw stem rising through handwheel type gate valve.Usually on lifting bar, have trapezoidal thread, by the guide groove on the nut of valve tip and valve body, rotary motion is become straight line motion, namely operation torque is become operation thrust.During Open valve, when flashboard lifting height equals the 1:1 times of valve latus rectum, the passage of fluid is completely unimpeded, but operationally, this position cannot monitor.During actual use, be using the summit of valve rod as mark, namely open motionless position, as its fully open position.For considering that deadlock phenomenon appears in temperature variation, usually reaching on dot location, then refunding 1/2-1 circle, as the position of standard-sized sheet valve.Therefore, the fully open position of valve, by the position of flashboard, (namely stroke > determines.Some valve rod nut for gate valves are located on flashboard, and hand wheel rotating band ovable valve stem rotates, and flashboard is promoted, and this valve is called swingle gate valve or is inside screw non-rising stem type gate valve.
The producer of domestic production gate valve is many, and Conncetion cimension is scarcely unification also.Main point following large class: based on the general class of JB/T2203-1999 " gate valve structure length ".Current most domestic safety valve manufacturer all produces by this standard design.Hand sluice valve working principle: rotate handwheel, by the forward and back of the screw thread of handwheel and valve rod, promotes or valve plate that decline is connected with valve rod, reaches the effect of opening and closing.By housing/material of main part classification, gate valve can be divided into: metallic material valve: as carbon steel valve, alloyed steel valve, stainless valve, cast iron valve, titanium alloy valve, Monel valve, Cuprum alloy valve, lead alloy valve etc.Metal valve body lining valve: as line with rubber valve, fluorine-lining valve door, lining with lead valve, lining mould valve, lining enamel valve.Nonmetallic material valve: as ceramic valve, glass valve,
plastic valve.
The open-shut device of gate valve is flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete shut-down, can not make adjustments and throttling.Flashboard has two sealing surfaces, and two sealing surfaces of the most frequently used pattern gate valve form wedge shape, key groove is different with valve parameter, and being generally 5 °, is 2 ° of 52' when medium temperature is not high.The flashboard of Wedge gate valve can make an entirety, is called rigidity flashboard; Also can make the flashboard that can produce micro-deformation, to improve its manufacturability, make up the deviation that sealing surface angle produces in course of working, this flashboard is called Flexible disc.When gate valve is closed, sealing surface can only rely on pressure medium to seal, and namely relies on pressure medium the sealing surface of flashboard to be pressed to the valve seat of opposite side to ensure the sealing of sealing surface, selfsealings that Here it is.Major part gate valve adopts forced seal, namely during valve closing, external force be relied on by force flashboard to be pressed to valve seat, to ensure the sealing of sealing surface.The flashboard of gate valve with valve rod moving linearly, makes lifting bar gate valve also be Outside screw stem rising through handwheel type gate valve.Usually on lifting bar, have trapezoidal thread, by the guide groove on the nut of valve tip and valve body, rotary motion is become straight line motion, namely operation torque is become operation thrust.During Open valve, when flashboard lifting height equals the 1:1 times of valve latus rectum, the passage of fluid is completely unimpeded, but operationally, this position cannot monitor.During actual use, be using the summit of valve rod as mark, namely open motionless position, as its fully open position.For considering that deadlock phenomenon appears in temperature variation, usually reaching on dot location, then refunding 1/2-1 circle, as the position of standard-sized sheet valve.Therefore, the fully open position of valve, determines by the position of flashboard and stroke.Some gate valves, Stem Mut is located on flashboard, and hand wheel rotating band ovable valve stem rotates, and flashboard is promoted, and this valve is called swingle gate valve or is inside screw non-rising stem type gate valve.
Gate valve only for the medium operation on standard-sized sheet, all kinds of pipeline of complete shut-down or equipment, does not allow to do throttling.With the gate valve of handwheel or handle, auxiliary regulations and parameters (if meet poorly sealed, then should check and repair sealing surface or other parts) during operation, must not be increased again.Handwheel, handle clockwise turn to closedown, otherwise then open.The gate valve of tape handler should use by the regulation of products instruction.The time that gate valve existing at present opens and closes is long, uses inconvenience.
