Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of three high gas flow cut-off valves, are applicable to the pipelines such as high temperature, high pressure and high-speed gas.
Background technique
Since China reform and opening-up, national economy rapid growth, scientific and technical innovation, autonomous innovation has become the main flow of domestic industry development, and China's industry is just step by step to the future development of intensive style, energy-saving and emission-reduction, low-carbon (LC).Stop valve, is also pipe valve, is one of most popular valve, due in switching process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, is not only applicable to mesolow, and is applicable to high pressure.The closed principle of stop valve is that dependence valve rod pressure, fits tightly valve clack sealing surface and sealing surface of seat, stops medium circulation.Traditional Oblique Stop Valve is many rotary and liftings bar cut-off valve, and the sealing force that moment of face produces need overcome pipeline pressure, therefore exists switch slow, and filler is easy to wear, and unlatching moment valve washes away seriously, and automatic control structure complexity operates the defects such as moment of torsion is large.And Oblique Stop Valve is in enable possition, main Sealing is exposed in runner, in the time of high-speed gas runner easily by quick erosion.The technician of R&D institution and enterprise is constantly exploring, is studying, and wishes to develop a kind of valve of superior performance, although obtained technically some progress, still exists the technical barrier not yet overcoming in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of three high gas flow cut-off valves are provided, have the advantage of stop valve and ball valve concurrently, be applicable to high temperature, high pressure and high-speed gas pipeline, there is the advantages such as flow resistance is little, sealing is reliable, life-span length, easy-to-operate, compact structure.
The utility model solves the technological scheme that its technical problem adopts: contain valve body, seal valve seat, spheroid, support valve seat, seating spring, pressure ring, jump ring, valve rod Lower shaft sleeve, stuffing box packing, filler pressing sleeve, Gland, valve rod, the anti-divided ring that flies, limiting board, gear-box, handwheel, the runner of valve body is cylindrical shape, its middle part is cavity, valve body top is provided with limiting board, limiting board is provided with gear-box, and valve body central authorities are provided with valve rod, and valve rod is connected with gear-box, gear-box is connected with handwheel, spheroid is housed in valve cavity, and spheroid top is connected with valve rod, and stem bottom and valve body contacting point are provided with valve rod Lower shaft sleeve, valve rod Lower shaft sleeve top is provided with stuffing box packing, stuffing box packing top is provided with filler pressing sleeve, and filler pressing sleeve top is provided with Gland, and valve rod middle part is provided with the anti-divided ring that flies for preventing that valve rod from being gone out by pipeline pressure with valve body contacting point, seal valve seat is pressed in valve body through valve body side canal, more laterally successively packs spheroid into, support valve seat, seating spring, pressure ring, and fix with jump ring.
The utility model solves the know-why that its technical problem adopts: ball valve is mainly for open and close pipeline and equipment medium, to use with the spheroid of circular channel to do open-shut device, by rotating handwheel, spheroid rotates 90 ° with valve rod, realizes the keying of valve.The open-shut device of ball valve is a porose spheroid, and this spheroid rotates around the axis perpendicular to passage, thereby reaches the object that opens and closes passage.Stop valve is to rely on valve rod pressure, and valve clack sealing surface and sealing surface of seat are fitted tightly, and stops medium circulation.This valve has the advantage of stop valve and ball valve concurrently, seal valve seat is pressed in valve body through valve body side canal, form pure metal sealing with valve body, pack valve rod into from valve body top, be loaded on the anti-divided ring that flies, prevent from surprisingly rupturing due to misoperation or because of valve rod, the accident that valve rod is gone out by pipeline pressure occurs, more laterally successively packs spheroid into, supports valve seat, seating spring, pressure ring, and fixes with jump ring, spring is compressed and produces pretension sealing force, guarantee when pipe medium pressure is low to realize reliable sealing.The operating principle of this valve is: external force 90 is spent rotation valve rod and driven spheroid rotation, in the time that spheroid passage aligns with valve channel, and valve wide open, pipeline is connected.In the time that spheroid passage is vertical with valve channel, valve complete shut-down, pipeline blocks.This valve is pressure self-sealing valve, and spheroid is axial free floating in closed position, and ball seal valve seat is formed initial sealing by the compressive force by seating spring when pressure medium is low, pressure medium increases, spheroid presses to that seal valve seat is tighter, and pressure is larger, and sealing force is larger.Stem bearing designs outside valve body, leaves thermal source, has reduced the moment of torsion of valve rod under worst hot case.For pure metal seals, do not exist conventional high-temperature ball valve sealing graphite to be washed away by high velocity air and the hidden danger revealed in valve body.This valve is at fully open position, and sealing surface and runner separate and be protected, on this valve actuator mounting bracket, with valve body be an entirety, avoid bolt to connect and loosening cause spheroid switch not in place, the hidden danger of the accelerated wearing and tearing of sealing surface.
The beneficial effects of the utility model are: this valve is 1/4th to turn self sealing valve, and switch is rapid, and erosive wear is little, and switching torque is light, more easily realizes automatic control, and work flow resistance is little, energy-conserving and environment-protective.Its valve body is monolithic construction, without valve body and valve bonnet seal, does not have because of temperature variation the leakage hidden danger that the factors such as material creep cause.Its valve rod is an entirety, avoids the wearing and tearing of two-segment type valve rod joint or becomes flexible and cause switch not in place, the defects such as the accelerated wearing and tearing of sealing surface.
