Abstract
The utility model is the dome head and pipe joint solid forging structure of a kind of water storage tank or separator, including：Dome head and pipe joint, dome head are pure hemispherical located at water storage tank or the two ends of separator, dome head, and solid forging shaping is used with pipe joint, are integrally formed structure, and seal head material uses 12Cr1MoV.It is Split type structure that existing supercritical boiler separator or water storage tank end ball end socket are solved with pipe joint thereon, need to be welded to connect, to ensure structural strength, dome head straight section wall thickness need to be more than the wall thickness of dome head, weld seam need to be detected a flaw, cause procedure of processing many, the problem of high cost.
Description
Technical field
The utility model is related to super critical boiler apparatus field, and in particular to the dome head of a kind of water storage tank or separator
With pipe joint solid forging structure.
Background technology
The dome head at existing supercritical boiler separator and water storage tank two ends is connected with pipe joint thereon using welding
Connect, dome head end is provided with straight section, thickness of the thickness much larger than spherical part according to the requirement of Strength co-mputation straight part, envelope
Head material must select material SA182F91 high-grade with cylinder identical, current dome head to be individually order with pipe joint
Forging, be welded to connect after going back to factory, then need to carry out post weld heat treatment and machining removal inner bushing ring, be to ensure connection matter
Amount, needs to carry out nondestructive inspection to weld seam, and costly needed for manufacture welding end socket and flaw detection, manufacturing process is more, and the manufacturing cycle is long.
The content of the invention
The purpose of the utility model is to provide the dome head and pipe joint solid forging knot of a kind of water storage tank or separator
Structure, its end socket can use the material of lower grade in the case where intensity requirement is met, and without welding, post weld heat treatment, machine
The step such as processing and the nondestructive inspection to weld seam, can reduce manufacturing process, reduce manufacturing cost and shorten the manufacturing cycle.
The utility model provides the dome head and pipe joint solid forging structure of a kind of water storage tank or separator, including：
Dome head and pipe joint, dome head is located at water storage tank and the two ends of separator, it is characterised in that dome head is pure hemisphere
Shape, solid forging shaping is used with pipe joint, is integrally formed structure, and seal head material uses 12Cr1MoV.
Water storage tank or the dome head of separator and pipe joint solid forging structure that the utility model is provided, using entirety
Forging molding, therefore without steps such as welding, post weld heat treatment, machining and the nondestructive inspections to weld seam, used with pipe joint
Overall structure, dome head is cost-effective and can meet intensity requirement using 12Cr1MoV materials without straight section, saves manufacture
Welding end socket and expense needed for flaw detection, manufacturing process are few, and the manufacturing cycle is short.
Brief description of the drawings
Fig. 1 is the dome head and pipe joint welding structure schematic diagram of prior art water storage tank or separator；
Fig. 2 is the dome head and pipe joint solid forging structural representation of the utility model water storage tank or separator.
Specific embodiment
Refering to illustrated in Figure 1, the welding structure of dome head and pipe joint in the prior art, its dome head end is provided with
Straight section, the thickness of the wall thickness much larger than land portions requirement of straight section requirement, pipe joint is fixed with dome head by welding and connected
Connect, and form weld seam, to ensure quality of connection, it is necessary to carry out post weld heat treatment, machine, and nondestructive inspection is carried out to weld seam.
Refering to illustrated in Figure 2, dome head and the pipe joint solid forging knot of water storage tank of the present utility model or separator
Structure, including：Dome head and pipe joint, dome head is located at water storage tank or the two ends of separator, it is characterised in that dome head
It is pure hemispherical, solid forging shaping is used with pipe joint, be integrally formed structure, seal head material uses 12Cr1MoV.
Every boiler is provided with 3 separators and 1 water storage tank, has 8 end sockets, using water storage tank of the present utility model or
After the dome head and pipe joint solid forging structure of separator, without operations such as welding, machining, seam inspections, material is reduced
Material grade, can save considerable cost, and significantly shorten the manufacturing cycle.
Claims (2)
1. the dome head of a kind of water storage tank or separator and pipe joint solid forging structure, including：Dome head and pipe joint,
Dome head is located at water storage tank and the two ends of separator, it is characterised in that dome head is pure hemispherical, with pipe joint using whole
Body forging molding, is integrally formed structure.
2. dome head as claimed in claim 1 and pipe joint solid forging structure, it is characterised in that seal head material is used
12Cr1MoV。
