Description
Technical field
The utility model relates to a kind of corrugated expansion joint, specifically a kind of compound type corrugated expansion joint, belongs to compensator field.
Background technique
Bellows is a kind of cylinder-shaped thin wall elastic shell with transverse wave, existing more than 100 year of its production history.Until World War II period, just be used as instrument, the elastic sensing element of instrument and the linkage element of various pipes, now be widely used in the engineering equipments such as mine, oil, chemical industry, metallurgy, electric power, heating power, navigation, space flight, play sealing, absorbing, noise reduction, energy storage, thermal compensation and medium buffer action, the main performance of bellows is that it is flexible, but its flexibility is subject to the restriction of its strength and stability.In order to ensure the compression resistance of bellows, its wall thickness can be increased, but flexibility decreasing, not reaching the effect of compensate for displacement, vibration-absorbing denoising, if increase flexibility by increasing wave number, then facing post destabilization problems; If increase flexibility by increasing wave height, then cause stress amplitude to improve, strength reduction, fatigue life reduces, and also there is plane instability problem.Therefore, we provide a kind of compound type corrugated expansion joint.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of compound type corrugated expansion joint, and structure is simple, connect closely, flexural stress is little, not easily plane instability occurs, particularly suitable high pressure, small deformation, bigbore occasion, satisfy the demands with this.
For achieving the above object, the technical solution adopted in the utility model is: a kind of compound type corrugated expansion joint, comprises end pipe, end plate, intervalve, work bellows, threeway, balance bellows, pull bar, spherical washer and end socket; Described end pipe is arranged on overall side and is positioned at the top of intervalve; Described end plate be separately positioned on end pipe top and end socket bottom and closely weld; Described work bellows is horizontally set on intervalve, and is attached to the both sides of intervalve; Described intervalve is arranged on the inside of work bellows; Described threeway is arranged on the right side of work bellows and is welded to connect with intervalve and is communicated with intervalve inside; Described balance bellows is arranged on the side of threeway and one end arranges pull bar; Described spherical washer to be arranged between end plate and pull bar and compact siro spinning technology; Described end socket is arranged on balance bellows one end.
Further, the lower end of described threeway and intervalve compact siro spinning technology, and threeway is cone structure.
Further, described balance bellows is thread-shaped structure.
Further, described spherical washer is arranged on the right-hand member of end socket, and spherical washer is arc-shaped structure.
Further, described balance bellows is one-time formed device.
The beneficial effects of the utility model are: this work bellows has two, and fore channel section is installed, the lateral displacement produced from bend loss can be absorbed, described balance bellows is arranged on the balance end at overall rear portion, the axial displacement produced from straight length can be absorbed, when bend loss produces lateral displacement, on pull bar, Ball faced nut rotates around spherical washer, draw the thrust can bearing interior pressure simultaneously, therefore this device can be arranged on steam turbine, the outlet port of compressor, to reduce the active force to them, bellows set size is accurate, surface nondestructive is hindered.Therefore; the bellows anti-corrosion capacity that the method manufactures is strong; fatigue life is high; that current bellows manufactures most advanced, the most reliable technological method of quality; described stainless steel has fabulous decay resistance; can protective conduit preferably; more alloying element can be dissolved in nickel-base alloy; and can good structure stability be kept; alloy is effectively strengthened; obtain than iron-base superalloy and the higher hot strength of cobalt base superalloy, three is have anti-oxidant and resistance to combustion gas corrosion ability more better than iron-base superalloy containing the nickel-base alloy of chromium.
