Abstract
A corrugated pipe instrument five-valve set is composed of a valve body, a valve element, a lower valve rod, a metal gasket, a metal corrugated pipe, a valve seat, a valve deck, fillers, a filler cushion, a steel ball, an upper valve rod, a sealing gasket, a filler ring, a sealing pressing gasket, a pressing nut and the like. The valve body is a carrier body which is machined to be in a cuboid shape and integrates five valves. Two internal thread valve cavities are formed in the two ends of the valve body respectively, and three internal thread valve cavities are linearly arrayed in the middle of one side of the valve body. Passageways of the valves can be freely switched through a switch. The valve element, the lower valve rod and a flange are directly welded to the metal corrugated tube and arranged among the valve body, the valve seat and the valve deck. The upper valve rod is movably connected with the lower valve rod through the steel ball. The high-temperature and high-pressure corrugated pipe five-valve set is high in sealing reliability and safety performance, and the multi-level safety protection structure that the metal corrugated pipe is shielded and sealed, the lower valve rod is sealed through the fillers, and the upper valve rod is also sealed through the fillers is achieved.
Description
Technical field
The utility model relates to design and the manufacture of valve, is widely used in liquid in the instrumentation pipelines such as all kinds of flows, differential pressure, pressure of industrial automation control system or keying and the control gear of gas.
Background technique
At present, present instrument five valve groups all realize sealing by filler, owing to there being motion between filler and valve rod, produce inevitable friction and wear factor, thereby structurally exist the possibility of leakage, and some medium (as: high temperature, high pressure, poisonous, inflammable, explosive, have radioactivity etc. to work the mischief to safety, environment and biological health) has not allowed to leak outside.The current bellows stop valve structure of China is single, can only be applied under the working condition of low pressure, low temperature and security medium, and working life is short, is not suitable for high temperature, high pressure and occasion dangerous or that may damage environment, life.
Summary of the invention
The purpose of this utility model is to provide a kind of bellows instrument five valve groups with the spacious sealing of the peripheral pressurized screen of metal bellows, spool is together with lower valve rod and flange is direct and metal bellows welds and is placed between valve body, valve seat and valve gap, upper valve rod and lower valve rod adopt that steel ball is active to be connected, the spacious sealing of wavy metal tube panel, lower valve rod packing seal and the upper valve rod gland sealed multiple security structure again of carrying out valve group are a kind of High Temperature High Pressure Bellows valves groups with highly reliable sealing and high safety performance.
Technological scheme of the present invention is:
1, a kind of bellows instrument five valve groups, by valve body, spool, lower valve rod, metal washer, metal bellows, valve seat, valve gap, filler, Packing seat, steel ball, upper valve rod, sealing gasket, insertion ring, sealed pressure pad, gland nut etc., formed, it is characterized in that: valve body is 5 integrated carriers of valve being processed into by a cuboid, wherein internal thread valve pocket B1 and B5 are respectively at valve body two ends, and internal thread valve pocket B2, B3, B4 distinguish the neutral position of linear array in valve body one side; Internal thread valve pocket lower hole C1 communicates with internal thread valve pocket lower hole C2 and C3 and entrance F1 respectively, internal thread valve pocket B1 communicates with internal thread valve pocket base apertures E1, internal thread valve pocket B2 communicates with outlet D1, internal thread valve pocket lower hole C5 communicates with internal thread valve pocket base apertures E2 and internal thread valve pocket lower hole C4 and entrance F2 respectively, internal thread valve pocket B5 communicates with internal thread valve pocket base apertures E3 and outlet H2, and internal thread valve pocket B4 communicates with outlet D2; There are respectively 2 symmetrical mounting hole G both sides, middle part.
2, metal bellows is made by one deck to the equal thin metallic tubd of multilayer wall thickness, according to the height of valve pressure and temperature, determine respectively the different number of plies and wall thickness, its length, the pitch of waves, wave number and inner and outer diameter design according to technical parameters such as the flow of valve, latus rectum, switching paths; One end of lower valve rod coordinates with spool, and the other end is hole, and the bottom in hole is plane, uniform multiple apertures on the relevant position of its circumference, and the lower end surface of upper valve rod is circular arc, has arc-shaped groove on excircle; Metal bellows is enclosed within on lower valve rod, one end and lower valve rod bottom, the other end and flange welding sealing, spool and lower valve rod welding, upper valve rod is inserted in the hole of lower valve rod, circular arc end face is contacted with the base plane in hole, in each aperture, pack the steel ball of same size into, simultaneously steel ball is placed in the arc-shaped groove of upper valve rod bottom, make upper valve rod and lower valve rod by steel ball active couple together; Be placed in valve seat, after flange has respectively packing ring and valve gap to closely cooperate up and down, lower locknut locking, filler and Packing seat are housed in valve gap, screw adjusting element its promotion Packing seat is pressed on filler between lower valve rod and valve gap, upper locknut is screwed to locking, form packing seal; On adjusting element top, pack sealing gasket, insertion ring, sealing clamping ring into, regulate and screw gland nut, form insertion ring and seal again; Load onto handle or handwheel, form valve group top assembly.
3, the valve seat of top assembly is loaded onto to metal washer and screw in respectively 5 internal thread valve pocket B1～5 of valve body fastening, between the internal thread valve pocket B oral area of valve seat, metal washer and valve body, seal; Rotatable handle or handwheel, upper valve rod spiral lifting, under the effect of the active linkage structure of steel ball, makes lower valve rod and spool not rotate upper and lower straight line motion, carries out and opens and closes.
4,5 integrated each architectonicals of valve, open internal thread valve pocket B1 upper valve, while closing internal thread valve pocket B2 and internal thread valve pocket B3 upper valve simultaneously, entrance F1 with outlet H1 communicate, then open internal thread valve pocket B2 again with outlet D1 communicate; Open internal thread valve pocket B5 upper valve, while closing internal thread valve pocket B4 upper valve simultaneously, entrance F2 with outlet H2 communicate, then open internal thread valve pocket B4 again with outlet D2 communicate; While opening internal thread valve pocket B3 upper valve, be all communicated with each 2 valves of both sides; So open or close any switching channel each other.
Advantage of the present invention and beneficial effect are:
1, the present invention adopts the spacious sealing of the peripheral pressurized metal screen of metal bellows and metal washer hard sealing structure; high temperature high voltage resistant sealability excellence, reliable; there is again the protection of high temperature high voltage resistant filler secondary seal; preventing having realized double-sealing, dual fail-safe aspect external leakage, be specially adapted to high temperature, high pressure and the aspects such as health, safety, environment had to medium and the occasion of harm.
2, because metal bellows and lower packing seal all concentrate in lower valve rod one, during operated valve, lower valve rod does not rotate and moves up and down in filler and metal bellows, friction between filler and the lower valve rod greatly reducing, has improved working life and the operating characteristics of valve greatly.
3, between upper and lower valve rod, adopt the active linkage structure of steel ball, spin friction active force is dropped to minimum, make the operation of valve free and relaxed.
4, due to the seal action of upper insertion ring, make it with outside isolated, be not subject to external environment influence.
5, prevent that valve group from opening or closing loosening, be applicable to being applied in the occasion of vibrations.
