Abstract
The utility model provides a flat hemisphere head relates to steam stabilizer head and makes technical field, provides a hemisphere head that can be used for steam stabilizer. The flat-bottom hemispherical head comprises a hemispherical side (1), a flat bottom (2) and an electric heating rod (3). The utility model relates to a flat hemispherical head atress is good, flat bottom diameter is not big, has also reduced the material cost of equipment when reducing the equipment manufacture degree of difficulty.
Description
Technical Field
The utility model relates to a technical field is made to steam regulator head, concretely relates to flat hemisphere head.
Background
With the development of nuclear power industry, steam regulators are applied more and more widely in the nuclear power industry, the steam regulators are generally high-temperature and high-pressure equipment, the seal heads are generally hemispherical seal heads, a plurality of electric heating elements are arranged on the lower seal head of the equipment, and water in the equipment is heated to generate steam so as to achieve the purpose of stabilizing the pressure. The electric heating element sleeve pipe lug weld is on the head, and the head camber is big, and the intersecting line overlength is difficult to weld thoroughly, and the welded degree of difficulty is very big, and the sheathed tube deformation of welding back electric heating rod is very big moreover, and later stage secondary operation can lead to the thickness of guide sleeve pipe uneven appearing, and the phase difference is great, can not satisfy the strength requirement even.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a flat hemisphere head sets up to flat through the bottom with hemisphere head, has guaranteed the accurate location of electrical heating stick and the intensity requirement of device. The utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a flat-bottom hemispherical head, which comprises a hemispherical side edge and a flat bottom; wherein:
alternatively or preferably, the flat bottom is welded to the hemispherical side;
optionally or preferably, a plurality of electric heating rods are further arranged on the flat bottom.
Alternatively or preferably, the electrical heating rod penetrates through the flat bottom.
Alternatively or preferably, the electrical heating rod is mounted on the flat base by welding.
Alternatively or preferably, a full penetration welded structure is adopted between the flat bottom and the hemispherical side edge.
Based on the technical scheme, the following technical effects can be generated:
the embodiment of the utility model provides a pair of flat hemisphere head is fit for as steam stabilizer's head. The utility model relates to a flat hemisphere head is established to flat through the bottom with hemisphere head to set up the electrical heating stick on flat, solved traditional hemisphere head camber too big, intersecting line overlength, difficult welding, the problem that the welding degree of difficulty is big. The utility model relates to a flat head atress of hemisphere is good, has reduced the equipment manufacture degree of difficulty, has also reduced the material cost of equipment.
