Abstract

The invention provides a cut-off device, comprising a body, and an elastic element, a brake element, a water retaining pad, a water inlet disc and a washer which are arranged in the body sequentially along the direction from the downstream to the upstream; the water retaining pad is made of soft material; the water retaining pad and the water inlet disc are provided with water inlet holes; furthermore, the water inlet hole of the water retaining pad and the water inlet hole of the water inlet disc are staggered with each other; wherein, the internal wall of the body is provided with a first terrace edge, a second terrace edge, a third terrace edge and a fourth terrace edge which are respectively butted to the elastic element, the water retaining pad, the water inlet disc and the washer; the body and the position corresponding to the second terrace edge are provided with permeable holes which are communicated with the interior of the body; the circumference of the water retaining pad is provided with a labial margin which is warped upwards. As the circumference of the water retaining pad is provided with the labial margin, the elastic pressing of the water retaining pad is more flexible; meanwhile, the water retaining pad is not deformed owning to the increased locking strength of a pipeline.

Description

technical field

[0001] The invention relates to a water breaker. Background technique

[0002] Fig. 1 shows a three-dimensional exploded view of a traditional water breaker. The body 10 of the water breaker is mainly composed of an upper joint 11, a lower joint 12, a washer 13, an elastic element 14, a water stop pad 15, and a brake element 16; wherein: the upper joint 11 and the lower joint 12 are provided with two The inner threaded part 111 and the outer threaded part 121 of the pipelines 1 and 2 are locked, and the upper joint 11 and the lower joint 12 are provided with an outer threaded part 112 and an inner threaded part 122 that can be locked with each other at the joint, and are matched with the outer threaded part at the same time. A washer 13 is set between 112 and the internal thread portion 122. The bottom surface of the upper joint 11 is provided with a plurality of water inlet holes 113 arranged at equal intervals along the circumferential direction. The firs...
