Abstract
The utility model relates to a ball compensator for an industrial pipeline, particularly a pressurized block ball compensator, which is composed of a compensator body, a ball body, a press cover, a sealing ring, a middle sealing ring, a connecting flange, etc., wherein, a plurality of filling cylinders for blocking are arranged on the compensator body of the ball compensator, a stuff hole communicated with the gap of two middle sealing rings of an inner cavity of the ball compensator is arranged in the filling cylinder, and a pressure injecting screw rod is arranged on the stuff hole. When the pressure injecting screw rod on the leakage position of the filling cylinder is screwed down, sealed filling materials is filled, and the screw rod is tightened; then, the sealed filling materials can be extruded into the gap for achieving the goal of blocking without parking; thereby, the reliability and the economical efficiency of the system operation can be increased.
Description
The utility model has related to the temperature compensation device of industrial pipeline, is particularly for a kind of pressure sealing spherical compensator, is applicable to that various industrial pipelines such as petrochemical industry, steam, coal gas use, and also can be used in the city heat supply pipeline.
In existing industrial pipeline compensation device, advantage such as spherical compensator is big with its compensation ability, and distortional stress is little, and is easy for installation and being widely used.But press in operation or the frequent starting at band, once occur leaking when needing leak stopping, this ball is mended device often to be needed left alone without help car, tightens the attaching nut and make the gland crush seal encircle tight sphere, can realize leak stopping, and labor intensity is big, makes troubles to use.
The purpose of this utility model is to release a kind of spherical compensator of realizing not left alone without help car leak stopping--pressure sealing spherical compensator, mends the reliability and the Economy of device work to improve ball, convenient effect, energy saving.
Task of the present utility model is to realize by the way that installs a filler cylinder on the shell of mending device at ball additional.
Concrete spherical compensator is made up of parts such as body, spheroid, seal ring, intermediate seal ring, gland, adpting flanges.Spheroid is assemblied in the body, and seal ring and intermediate seal ring are housed between body and spheroid, and a gland is arranged on the end face of body, and gland is pressed on the seal ring with the attaching nut.Body and spheroid one end of mending device at ball are equipped with adpting flange respectively.The utility model also is provided with several filler cylinders on the body of ball benefit device, the filler cylinder is a middle cylindrical body that has stuffing hole, be welded on the shell of body, stuffing hole is connected with the space that ball is mended device inner chamber two intermediate seal rings, on the material hole of filler cylinder a pressed injecting screw rod is housed.The body that ball is mended device is a tubular foundry goods or a member, and spheroid is made up of spherical crown and ball neck two-part, and spherical crown is 1.4:1 with the ratio of the external diameter of ball neck, and the full folding angle in the wrong that ball is mended device is 30 °.In order to guarantee the sealing of ball device and pipeline junction, the adpting flange of the utility model spheroid end has loose flange and two kinds of the flanges of pressurized container that is threaded, ball is mended the device latus rectum? mend device less than the microspheric form of 250mm and can adopt the flange that is threaded, mend device for latus rectum greater than the ball of 250mm and easily adopt the pressurized container flange.
The body of ball benefit device and the material of spheroid are different according to operating temperature and working pressure, can be carbon steels, and Cr-Mo steel also can be a stainless steel.
During the utility model leak stopping,, insert stuffing box packing, tighten screw rod, stuffing box packing be pressed in the space of leakage position and can stop leaking as long as back out pressed injecting screw rod on the leakage position filler cylinder.
It is 100-1000(mm that the ball that the utility model provides is mended the device inside nominal diameter), working pressure is 1.6MPa-4.5MPa, operating temperature is 350-700 ℃.
Great advantage of the present utility model is can realize the not left alone without help car pressure sealing of ball benefit device owing to be provided with the filler cylinder on ball benefit device, has dosed reliability of system operation, has reduced the construction cost and the maintenance expenses of system.
Concrete structure of the present utility model is provided by following embodiment in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of the utility model filler cylinder
Below in conjunction with accompanying drawing the utility model is described further:
As figure (1) is that body, (2) are pin for logical (closing) material hole, (17) for overcoat, (18) for stuffing hole, (16) for material hole, (15) for stopcock, (14) for cylinder body, (13) for pressed injecting screw rod, (12) for adpting flange, (11) for nut (9), (10) for connecting bolt, (8) for gland, (7) for spheroid, (6) for filler cylinder, (5) for intermediate seal ring, (4) for seal ring, (3).Spheroid (5) is assemblied in the body (1), compress with gland (6) sealing, seal ring (2) and intermediate seal ring are housed between spheroid and body, (3) material of seal ring is looked ball to mend the operating temperature difference of device can be teflon, the asbestos composite material, or spheroidal graphite cast iron, the intermediate seal ring is a graphite composite material.Filler cylinder (4) is made up of cylinder body (12) and pressed injecting screw rod (11), being fixed on ball mends on the shell of device, have stuffing hole (15) and material hole (14) in the cylinder body (12), stuffing hole is a region between the heart and the diaphragm hole, not end at stuffing hole has four oblique material holes, material hole is to be on the garden perisporium that criss-crossing is distributed on stuffing hole, and the one end is communicated with stuffing hole, and the other end is connected with the space that ball is mended two intermediate seal ring places in the device inner chamber.The stopcock (13) that a relative cylinder body is radially settled also is housed on the filler cylinder, has radially logical (closing) material hole (16) on the stopcock, and be equipped with one in order to show the pin (18) of stopcock position.
According to the spherical compensator that present embodiment is manufactured, under different operating temperatures and working pressure, can effectively realize the not left alone without help car pressure sealing of ball benefit device, greatly facilitate use, saved the energy, improved work efficiency.
Claims (3)
1, a kind of by body (1), spheroid (5), gland (6), adpting flange (9), (10) spherical compensator of Zu Chenging, seal ring (2) and intermediate seal ring (3) are housed between body (1) and spheroid (5), it is characterized in that this ball benefit device is equipped with several filler cylinders (4) on the shell of body, the filler cylinder is made up of garden cylindricality cylinder body (12) and pressed injecting screw rod (11), have stuffing hole (15) and material hole (14) in the cylinder body, stuffing hole is a region between the heart and the diaphragm hole, material hole is four oblique apertures, open not end at stuffing hole, the one end is communicated with stuffing hole, and the other end is connected with the space that ball is mended two intermediate seal ring places in the device inner chamber.
