Abstract
The utility model discloses a special high-pressure difference angle valve for black water, which comprises a valve body with an inlet and an outlet which are perpendicular to each other, wherein a valve cover is fixedly mounted at the upper part of the valve body; a sweep-gas internal threaded interface is formed in the side part of the valve cover; an unthreaded valve seat is arranged in a space formed by the valve cover and the valve body, is directly mounted on the valve body and fixed by the valve cover through compression; a column type valve core with a multistage incision is mounted in the valve seat and fixed at and connected with the lower end of a valve rod; the upper end of the valve rod extends out of the valve cover to be connected with an output shaft of an actuating mechanism so as to move with the output shaft of the actuating mechanism; and the valve rod drives the column type valve core to move up and down in the valve seat, which realizes the automatic control for the medium flow by the valve. The special high-pressure difference angle valve solves the problems that a current black water self-control valve is low in adjustment precision, serious in inner leakage caused by cavitation, easy to get stuck, difficult in maintenance, and short in service life.
Description
Technical field:
The utility model relates to the internally piloted valve technology in Coal Chemical Industry industry technology field, is specifically related to a kind of Heisui River special high-pressure declinate valve.
Background technique:
Heisui River special-purpose long life high-voltage declinate valve is as one of crucial internally piloted valve of Coal Chemical Industry industry, ubiquity the problem that cavitation erosion is serious, degree of regulation is low and working life is short at present, interior in addition leakage is serious, easy stuck and keep in repair difficulty etc., has badly influenced the utilization efficiency of coal chemical engineering equipment.
The model utility content:
The utility model provides a kind of adjusting and the Heisui River special high-pressure declinate valve that cuts off occasion that is applicable to various to high pressure Heisui River, grey aqueous medium at the problem and shortage that prior art exists.
Technological scheme: a kind of Heisui River special high-pressure declinate valve, comprise valve body, valve gap, valve seat, valve rod and spool, wherein, described valve body is an import and the dihedral valve body that exports into 90 degree right angles, valve gap extends upward and valve rod suit mutually, and the sidewall of valve gap is provided with purge hole, and the purge hole plug is installed on the purge hole.
Described spool is a pillar spool with multistage otch, and this pillar spool is fixedlyed connected with valve rod, and the pillar valve core housing is loaded in the inner chamber of valve seat, and the intracavity sidewall of valve seat is provided with through hole.
Be provided with annular cavity between described valve gap and the valve rod, the bottom of this annular cavity is provided with Packing seat, is filled with filler in the annular cavity of Packing seat upside, and the upper end-hole of annular cavity is set with annular pressing, annular pressing upside is provided with annular pressing plate, and annular pressing plate and valve gap are fixed together.In described filler, be provided with spacer.
Be fixed with support on described valve gap, Pneumatic piston actuator is installed on the support, this Pneumatic piston actuator piston rod is connected with described valve rod.
Beneficial effect: Heisui River of the present utility model special high-pressure declinate valve, adopt angular structure, flow to side and enter the end and go out solid forging valve body and valve gap; Decompression separates the mentality of designing that realizes with Flow-rate adjustment, and the multistage nicked pillar valve core structure of design has self-cleaning function.Utilize the principle of pressure reduction with classification, make the influence of cavitation erosion araeosystyle spool, valve seat reduce to minimum, and guaranteed the flow curve of high definition.Pillar valve core structure with self-cleaning function prevents effectively not only that the particle in the Heisui River from entering pillar spool and valve seat gap and the valve stuck phenomenon that causes, and solved old-fashioned many valve core structures can't self-cleaning problem; Pillar spool and valve seat adopt whole tungsten carbide alloy or supersonic spray coating, unique valve rod and pillar spool linkage structure, promptly guaranteed the ultrahigh hardness of pillar spool, the toughness that has kept valve rod again, make whole valve that extraordinary sealing not only be arranged, and improved greatly the working life of each parts in the valve; Valve seat adopts long cover shape not have the direct loading type structure of screw thread, make the replacing of each parts in the valve more convenient, High Pressure Difference angle valve on-line maintenance becomes possibility, auxiliary steam purge hole on the valve gap, when overhaul of the equipments or stoppage in transit, can purge valve rod and filler, pillar spool and the fouling of valve seat sliding position and condensing of coal dust, thereby prolong the interval of the maintenance of disintegrating.Be equipped with high thrust Pneumatic piston actuator again, variety of issues such as having solved thoroughly that the present Heisui River ubiquitous degree of regulation of internally piloted valve is low, leak seriously in the cavitation erosion, easily stuck, maintenance difficulty and working life is short.
