Description

Anticorrosion composite pipe connects special welding flanged joint
Technical field
This practicality relates to a kind of pipe joint, particularly relates to a kind of anticorrosion composite pipe and connects special welding flanged joint, easy pressure testing welded stub connection.
Background technique
In recent years, double seal welding joint is because of easy construction, and loss, voltage withstand class are high, the features such as antiseptic property is excellent, connects technical field of sealing technology be used widely at anti-corrosion pipeline.The double seal welding joint of prior art is provided with elastomer seal by between two links, and during installation, two links are welded to connect outside link, thus realize the double-sealing of Sealing and outside weld part after drawing extruding rubber ring over to one's side.And prior art generally adopts pipeline entirety to suppress, not only consuming time, work consuming but also waste water resource, regional cost for water resources shortage is higher, therefore, develop one and can effectively intercept welding heat transmission, realize Sealing and coated inside harmless injure save time, laborsaving, economize on resources, the anticorrosion composite pipe welded stub connection reducing construction cost is objective demand.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of double-sealing welding type connecting body that adopts is provided, there is easy pressure testing and the high anticorrosion composite pipe of voltage withstand class connects special welding flanged joint, can not the plastics of melt painting and rubber seal when both having ensured to weld, can Site Welding be realized again, seal up to standard.
Rotten composite pipe connects special welding flanged joint, comprise the similar joint body being connecting end surface and being oppositely arranged of profile that two panels flange welding connects, described two joint body connecting end surface central authorities are respectively equipped with the circular hole being connected with pipe and coordinating, wherein the first flange plate joint body circular hole ring week connecting end surface on from the center of circle, radially be provided with annular seal groove with one heart successively, annular heat groove, and annularly heat dam radial direction be provided with by surperficial to its bottom land and this joint body UNICOM from verify, on second flange plate body end face, center of circular hole is had radially to be provided with successively, corresponding with the annular seal groove of above-mentioned flange plate body Liang Zhi tri-road water sealing line is set, corresponding with the annular heat groove of above-mentioned flange plate body heat dam is set
The further technological scheme of the utility model is, is provided with about 1mm and is not more than the gap of 1.5mm between the connecting end surface of described two joint bodies.
The further technological scheme of the utility model is, described annular heat groove quantity is together.
The further technological scheme of the utility model is, described annular seal groove quantity is 1 road.
The further technological scheme of the utility model is, the shape of described joint body is circular or square.
Be curvilinear structures between flange welding portion of the present utility model and elastomer seal, significantly extend the heat conducting path of welding, effectively pass to the destruction of heat to undercoating and elastomer seal when having intercepted flange welding, achieve " not damaged " and the integrity of coated inside, avoid sealing surface to occur because burning out leaking, utilize detect aperture to suppress the sealing of detecting tube joint simultaneously, save time, laborsaving, economize on resources.The utility model is convenient to site operation, and effectively reduces engineering cost under the prerequisite ensureing construction quality, is suitable for popularization.
Accompanying drawing explanation
Fig. 1 is the detailed schematic diagram of overall structure of the present utility model.
Fig. 2 is erection drawing of the present utility model.
Fig. 3 is the second flange front view of the present utility model.
Fig. 4 is the first flange front view of the present utility model.
In Fig. 1: 1-first flange plate, 2-second flange plate, 11,21-weld part, 3-heat dam, 31-heat dam, 4-waterline groove, 5-seal groove, 51-rubber seal, 6-detect aperture, 7-steel pipe, 8-undercoating (moulding layer, composite bed)
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises two pre-connection composite pipes, the first flange plate, the second flange plate, composite base 7 and composite pipe coating 8, between two flange plate end faces, elastomer seal 51 is installed, weld part 11 and 21 is provided with outside two flanges, it is characterized in that: described first flange plate end is provided with at least one heat dam 3, the detect aperture 6 be communicated with flange exterior edge face at the bottom of one road sealing groove 5 and a heat dam, second flange plate is provided with the heat dam 31 corresponding with the first flange plate, and the twice water sealing line 4 corresponding with seal groove.
The sealing surface of described first flange plate 1 and the second flange plate 2 is that plane waterline 4 adds rubber rectangular ring 51 with groove 5, adds the length of rubber sheet gasket radial direction and end face normal direction, makes it more corrosion-resistant, can provide and seal stability more reliably.
The utility model is adding man-hour, and the first flange plate only has one heat dam and a road sealing groove, and the second flange plate only has one heat dam and twice water seal wire casing, is therefore of value to large-scale promotion at the bottom of processing cost.
The utility model is when applying, first two joint bodies 1 in factory by steel, 2 are enclosed within pipe 7 port that is attached thereto and welding makes pipe respectively from joint body 1 respectively, the outside of 2 is drawn, then carry out coated lining technique and make finished product, its flange seal finishing coat and pipe coating are connected as a single entity, make it more corrosion-resistant, product is transported to job site, during laying, by flanged joint 1, the connecting end surface of 2 is relative, counterpart machine is used to be aligned, and compress, general gap is at about 1mm, and be not more than 1.5mm, directly carry out hoop to weld, finally utilize and suppress to being closed up water filling in the annular housing that formed by two annular self-inspection grooves (heat dam) from verify 6, pressure gauge is used to detect, detect pipe joint, two ends and whether have leakage.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to structure of the present utility model, every any simple modification equivalent variations above embodiment done according to technical spirit of the present utility model with modify the scope all belonging to the technical solution of the utility model.
