Abstract

A movable elbow heat-insulated assembly is provided. An outer sleeve layer (3) is divided into at least two pieces along the elbow circumference direction. A heat-insulated layer (2) is divided correspondingly to the outer sleeve layer (3). A fixed connecting element (7) is arranged at one end of the outer sleeve layer; every piece of the outer sleeve layer (3) is hinged with the fixed connecting element (7) respectively. Connecting elements (4) are arranged on neighboring piece edges of the divided outer sleeve layer (3) with intervals. The utility model has reasonable design and simple structure, which can be assembled and disassembled easily. Total bareness of the elbow surface and the welding line can be realized without damaging the heat-insulated layer, which greatly simplifies pipeline mending and checking management, reduces time for checking and cuts down operation and maintenance cost.

Description

Movable elbow insulation assembly parts

Technical field

The utility model relates to a kind of pipe insulating layer, and particularly a kind of have the movable elbow insulation assembly parts that can open composite structure.

Background technique

In petrochemical industry and other industrial production, be used for the pressure piping of mass transport, in order to guarantee when the conveying material, reduce heat loss, be fixed with thermal insulation layer in its periphery.Thermal insulation layer uses materials such as rock wool, complex magnesium aluminum silicate, composition silicate, polyamine fat vacuole foam, phenol formaldehyde foam, plastics, perlite usually; the outside materials such as thin aluminum top, glass fiber cloth, SPUA that adopt of thermal insulation layer are as overcoat; seal, waterproof and protection, be an integral body after the moulding.For preventing that pressure piping from crackle occurring because of corrosion thinning and weld seam, the generation accident, pipeline needs regular or irregular thickness measuring inspection, weld seam inspection such as need regularly or irregularly detect a flaw, painted.And easily produce the key position pressure tube elbow of states such as medium washes away, corrosion, because its thermal insulation layer all adopts fixed structure, be difficult to open and reuse, each inspection all will destroy original thermal insulation layer, and then recover, not only construction is comparatively loaded down with trivial details, and causes the loss of material, the increase of operating expenses.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved movable elbow insulation assembly parts is provided, and makes things convenient for installation, dismounting and pipe detection, reduces construction and maintenance expenses.

The purpose of this utility model can realize by following technical measures: this assembly parts comprises thermal insulation layer, jacket layer, thermal insulation layer, jacket layer is corresponding with the shape of pipe bend, jacket layer is a rigid pipe, at least be divided into two along the elbow circumferencial direction, the corresponding piecemeal of thermal insulation layer with jacket layer, be fixed in the jacket layer, be provided with fixedly fitting at jacket layer one end, fixedly the fitting stationary positioned is on heat-insulating cover, fitting is hinged respectively with fixedly for every jacket layer, can open or close up along the articulating point activity, piecemeal jacket layer adjacent edge correspondence is provided with coupling, coupling is provided with at interval, can be connected by coupling after the piecemeal thermal insulation layer closes up to be combined into an integral body, and is corresponding with the elbow shape.

Fixedly fitting can be journal stirrup, is fixed on the pipe hingedly with jacket layer, when needs are opened assembly parts, takes coupling apart, and thermal insulation layer and jacket layer are opened along the articulated elements axle center; When needs close up, it is closed along the articulated elements axle center, fix by coupling then.

The utility model is reasonable in design, adopt movable composite structure, can not destroy thermal insulation layer and realize that elbow surface and butt weld are all exposed, simplify the pipe detection hypervisor widely, shorten detection time, lower operating expenses and maintenance expenses, it is simple in structure, install, dismantle easily, have higher using value, needing to be widely used in regularly or the insulation of the bend part of casual inspection.

Description of drawings

Fig. 1 is a structural drawing of the present utility model;

Fig. 2 is a user mode reference drawing of the present utility model.

Embodiment

With reference to Fig. 1, this assembly parts comprises thermal insulation layer [2], jacket layer [3], jacket layer [3] is formed by two, semicircle shape for symmetry, two jacket layer [3] adjacent edge compartment of terrain correspondence is provided with coupling [4], can connect and be combined into an integral body, corresponding with the pipe bend shape, clamping bolt [5] is arranged on the coupling [4], take bolt [5] apart, can open assembly parts, at jacket layer [3] one ends fixedly fitting journal stirrup [7] is housed, journal stirrup [7] is fixed on the heat-insulating cover [8], and every jacket layer [3] all has articulated elements [6] and journal stirrup [7] hinged, can open or close up along journal stirrup [7] hinge axes activity, heat-insulating cover [8] is fixed on pipeline [1] outside, and staggers with position while welding, when closing assembly parts, can cover the weld seam [9] between elbow [10] two ends and the pipeline [1], see Fig. 2.

Thermal insulation layer [2] is fixed on jacket layer [3] the inside, by cast thermal insulation layer [2] and jacket layer [3] bonding is linked to be integral body.Thermal insulation layer [2] can be made of a kind of thermal insulating material, also can be composited by the thermal insulating material of two kinds or more of unlike materials; Jacket layer [3] is made by rigid material such as steel plate or galvanized sheet etc., and it is fixed thereon to be convenient to above-mentioned coupling [4].

When needs carry out elbow [10] detection, the bolt [5] on the coupling [4] is taken apart, to open along the axle center of articulated elements [6], whole elbow [10] can all expose out, observes the whole outer surface and the weld seam [9] of elbow [10], and its state is referring to Fig. 2; When detection is finished, assembly parts is closed along the axle center of articulated elements [6], then that bolt [5] is fastening, whole elbow [10] all is in airtight insulation, and its state is referring to Fig. 1.
