Abstract

The invention discloses an automatic adjusting pressure reducer. A regulating valve rod which can move in the axial direction in a reciprocating is arranged in a decompression tube, automatic resetting control is performed by using an elastic member, and a water inlet sealing control ring and a water outlet sealing control ring move by following the adjusting valve rod and the corresponding portions shield and open a water inlet hole and a water outlet hole to enable a water outlet pipe to flow out constant pressure water flow. The automatic adjusting pressure reducer has the advantages of simple structure, no need for additional power control and convenient use.

Description

【Technical field】 [0001] The invention relates to a decompression device, in particular to an automatic regulating decompressor. 【Background technique】 [0002] In existing water heaters, the cold water input end is usually directly connected to the tap water pipe. For tap water in some areas or communities, the water pressure is unstable, and the water pressure supplied is too high or too low, which affects the normal use of users. [0003] The present invention provides an automatic regulating pressure reducer aiming at the deficiencies of the prior art. 【Content of invention】 [0004] The technical problem to be solved by the present invention is to provide a self-adjusting pressure reducer, in which an adjusting valve stem that can reciprocate in the axial direction is provided in the pressure reducing pipe, and an elastic member is used for automatic reset control, and the water inlet sealing control ring and The water outlet sealing control ring moves the water regu...
