Abstract
The invention relates to a two-valve group of a corrugated pipe instrument. The two-valve group of the corrugated pipe instrument comprises a valve body, a valve element, a lower valve rod, a metal washer, a metal corrugated pipe, a valve seat, a valve cover, fillings, a filling cushion, a steel ball, an upper valve rod, a sealing cushion, a filling ring, a sealing press pad, a press nut and the like. The valve body is a carrier of which two valves are integrated and formed by machining a cuboid. Two inner thread valve cavities matched with the valve seat are distributed at two adjacent side positions of the valve body respectively. The valve element is directly welded to the metal corrugated pipe together with the lower valve rod and a flange and arranged among the valve body, the valve seat and the valve cover. The upper valve rod and the lower valve rod are movably connected through the steel ball. A multiple-insurance structure according to which the metal corrugated pipe of the valve group is sealed in a screen opening mode, the lower valve rod is filled with the fillings and sealed and the upper valve rod is filled with the fillings again and sealed is adopted and the two-valve group of the corrugated pipe instrument is a high-temperature high-pressure corrugated pipe valve group with the highly reliable sealing performance and the high safety performance.
Description
Technical field
The present invention relates to design and the manufacture of valve, be widely used in liquid in the instrumentation pipeline 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, the instrument two valve groups of extensive use 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 object of the present invention is to provide a kind of bellows instrument two 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 wavy metal tube panel of carrying out valve group opens sealing, lower valve rod packing seal and upper valve rod gland sealed multiple security structure again, is a kind of High Temperature High Pressure Bellows valves group with highly reliable sealing and high safety performance.
Technological scheme of the present invention is:
1, a kind of bellows instrument two 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, the compositions such as gland nut, it is characterized in that: valve body is two integrated carriers of valve being processed into by a cuboid, two internal thread valve pocket B that coordinate with valve seat and C are distributed in respectively two lateral location that valve body is adjacent, wherein internal thread valve pocket B communicates with 2 outlet thread bottom hole H, internal thread valve pocket 1 lower hole E communicates with entrance thread bottom hole F, internal thread valve pocket 2C communicates with 1 outlet thread bottom hole I, and internal thread valve pocket 2 lower hole D communicate with entrance screw thread lower hole G.There is respectively a symmetrical mounting hole K 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 a plurality of 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, the steel ball that packs same size in each aperture 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 internal thread valve pocket B and the C fastening that metal washer screws in respectively valve body, 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, two integrated each architectonicals of valve, when opening the upper valve of internal thread valve pocket B and closing the upper valve of internal thread valve pocket C, entrance communicates with 2 outlets; When opening the upper valve of internal thread valve pocket C and closing the upper valve of internal thread valve pocket B, entrance communicates with 1 outlet; When two valves all open or close, entrance communicates simultaneously or cuts off with 1 outlet and 2 outlets.
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 is excellent, 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, the filler greatly reducing and the friction between lower valve rod, 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.
