Abstract
The utility model discloses a weld hydraulic enclosing cover for boilers and pressure vessels. During the hydraulic pressure test of conventional boilers and pressure vessels in plants, a hydraulic enclosing cover welded with a welding nozzle via a large-caliber adapter on construction sites and served as a temporary pressure part during the welding process is usually manufactured by the gas cutting, blanking and processing of a steel plate and the flat welding structure of the hydraulic enclosing cover is poor in bearing property. Meanwhile, the steel plate is thick and heavy and the obtained hydraulic enclosing cover is usually disposable, so that the waste is particularly large in quantity. The utility model provides a weld hydraulic enclosing cover for boilers and pressure vessels, which comprises an enclosing cover (1). More than one hydraulic allowances (2) are arranged at the lower end of the enclosing cover. The enclosing cover equipped with a center hole (4) is connected with a flange (3). The weld hydraulic enclosing cover is used for manufacturing boilers and pressure vessels.
Description
Technical field:
The utility model belongs to boiler and pressurized container is made the field; Be specifically related to a kind of welding hydraulic pressure capping that is used for boiler and pressurized container.
Background technique:
In traditional boiler both domestic and external and the pressurized container product factory during hydrostatic test, the heavy caliber of building site bevel for welding is taken over the hydraulic pressure capping of dress weldering, it all is interim pressure parts as welding, generally all be to process by the steel plate oxygen-acetylene cutting, its dull and stereotyped welded structure force-bearing situation is poor, steel plate is thick and heavy, all is disposable use usually.Especially big, the big capping in batches of product lot quantity pressure parameter height, the size of producing, exist repeat in a large number to make, the problem of high material consumption, deficiency in economic performance.
Summary of the invention:
The purpose of model utility provides the capping of a kind of novel welding hydraulic pressure, has further optimized the manufacturing process of capping, realizes that capping is improved to " lid is repeatedly used ", the purpose that reach energy-saving and cost-reducing, improves stock utilization and economic benefit by disposable use.
Above-mentioned purpose realizes by following technological scheme:
The welding hydraulic pressure capping of boiler and pressurized container, its composition comprises: capping, described capping lower end have once above hydraulic pressure surplus, and described capping adpting flange has center hole in described capping.
The welding hydraulic pressure capping of described boiler and pressurized container, described capping are spherical capping, oval capping, flat capping, tube sheet capping, dull and stereotyped capping or flange capping.
Beneficial effect:
1. the utility model has overcome that in the past closure construction is single, force-bearing situation is bad, steel plate is thick and heavy, only can disposablely use according to design, and is discarded afterwards.The narrow limitation that high material consumption, utilization ratio are low, manufacture cost is high and the shortcoming that cause.
Manufacturing process of the present utility model is optimized more; Realized " one lid many with ", improved several times～tens times of the utilization ratio of cover closing material and economic benefits.
Test pressure parameter of the present utility model is high more, the capping Dimensions is big more, the repeated use number of times is many more, economic benefit is just remarkable more.
The utility model technology novelty, practicality, advanced person, reliable; Broken through the prejudice in domestic and international this field, be specially adapted to use when boiler and pressure vessel manufacturers product lot quantity are produced.
Hydraulic pressure capping of the present utility model has 6 kinds of forms such as sphere, ellipse, flat, pipe-plate, flat board, flange, is fit to the boiler of multi-form, different structure, different pressures; Boiler of feeding and pressure vessel manufacturers are selected according to production actual conditions and needs.
Capping of the present utility model can be repeatedly, reuse, technology advanced person, with high content of technology, eliminated in the past and after the each hydrostatic test of product the disposable backward way of scrapping has been cut off in capping, realized being sealed under the situation of proof strength and usage requirement, " lid to be used more ".
