Description
Technical field
The utility model relates to a kind of high-pressure pipe connector preventing weld corrosion.
Background technique
At present at solar energy, in air source hot pump water heater, there is the structure that coil condenser is set in press-bearing water tank, what walk in coil pipe is high-pressure medium, be connected with outer machine or external equipment and generally connected by joint, as shown in Figure 3, generally that joint (3 ') outside is welded with water tank (2 ') now, the endoporus of joint (3 ') welds with metal coil pipe (1 ') in water tank, thus cause weld seam to be directly immersed in water tank medium, easily corrode weld seam, affect the working life of equipment.
Summary of the invention
In order to the weld seam solving current weld place is directly immersed in water tank medium the problem causing weld corrosion, affect service life of equipment, the utility model proposes one avoids weld seam directly to soak in water, and structure prevents the high-pressure pipe connector of weld corrosion simply and easily.
A kind of high-pressure pipe connector preventing weld corrosion described in the utility model, comprise the water tank with metal coil pipe and high-pressure pipe connector, it is characterized in that: described high-pressure pipe connector comprises band externally threaded fittings body, seal ring, tapped pipe joint, the through hole coordinated with metal coil pipe is provided with in described fittings body, described fittings body one end is provided with and coordinates with water tank flanging bore and the step that can weld with it, and the other end is provided with for the welding reducing of weld metal coil pipe and the outside thread for being spirally connected with pipe joint; Described metal coil pipe runs through the through hole of whole fittings body and welds in welding reducing place of fittings body, and metal coil pipe stretches out the partial insertion ring inner hole of fittings body, and the external part of described metal coil pipe is against in the tolerance hole of pipe joint inwall; Inside and outside the weld seam of whole high-pressure pipe connector and metal coil pipe, side medium is isolated.
Described pipe joint is provided with the internal thread of arranged in co-axial alignment, the taper hole that leads, fitting surface, compression cone, tolerance hole from outside to inside successively, and the outer wall of one end of pipe joint is provided with the connecting thread for connecting external equipment screw thread.
The extrusion that described metal coil pipe stretches out fittings body is greater than seal ring length.
Described seal ring is that softer metals is made, preferred red copper seal ring.
Described pipe joint adds with water tank face and metal coil pipe surface of contact AB glue of resinizing inside water tank.
Installation process: the external part of metal coil pipe is through fittings body through hole, and at external part welding (extrusion is greater than red copper seal ring length) after stretching out certain length, the step of the fittings body the other end welds after coordinating with the flanging bore of water tank, metal coil pipe external part puts seal ring, and pipe joint is welded by seal ring compacting sealing after tightening with fittings body again.
The beneficial effects of the utility model are: stop to manage inside and outside medium and bead contact, prevent the corrosion of weld joint, improve sealing reliability, and structure is simple, easy for installation.
