Description
Technical field
The utility model relates generally to water heating fittings, specifically a kind of Double-linkage bend.
Background technique
Conventional gondola water faucet or bathtub mix the center hole distance of water valve is on the market all GB 15cm, traditional construction first the spacing of tooth PPR elbow in two independences is adjusted to about 15cm, mated formation after ceramic tile by " the eccentric bent pin of reducing " precisely adjustment center hole apart to 15cm, then screw on mixed water valve trim and mixed water valve.In this process, two interior tooth PPR elbows are difficult to accomplish full symmetric and level, and any one elbow is located slightly deviation and is all easy to cause mixed water valve to install difficulty, even cannot install, can only pound the position that elbow readjusted by ceramic tile.
Having occurred a kind of double-joint female elbow at present, is placed side by side by the elbow of two interior teeth, by a connecting rod by two elbow center holes apart from being fixed as 15cm, still there is a lot of problem in use in this kind of double-joint female elbow, such as:
Although the center hole of 1 current double-joint female elbow is apart from being fixed as 15cm, being only difficult to ensure elbow level truly by range estimation in work progress, causing mixed water valve to be installed difficult.
2, double-joint female elbow interface size is all a kind of specification, also need during use, with the eccentric bent pin of reducing, interior tooth is become outer tooth, increase outer dental length to install mixed water valve trim and mixed water valve simultaneously, the eccentric bent pin of reducing is used on the double-joint female elbow of constant spacing, and only serve the effect of " reducing ", " eccentric bent pin " is just obviously unnecessary, also to readjust center hole distance on the contrary, both added workload and cost, and turn increased joint and to leak probability, also have impact on current size.
3, current double-joint female elbow middle brace rod is rectangle structure, though there is stiffening rib to be also easily distorted distortion.
4, be no matter two independent female elbows in traditional construction or double-joint female elbow, all need after the welding of a whole set of PPR circuit completes to screw on plug pressure testing at Nei Yachu, add certain workload.
