Pressure reduction device for domestic tap water pipes

Abstract

The invention discloses a pressure reduction device for domestic tap water pipes. The pressure reduction device comprises a water inlet manifold and a water outlet pipe. A pressure reduction mechanism is further connected between the water inlet manifold and the water outlet pipe. The pressure reduction mechanism comprises a pressure reduction segment, a fixing arm, a spring, a throat pipe opening and a piston. The fixing arm is fixed to the front end of the pressure reduction segment in the water flow direction. The throat pipe opening is fixed into the rear end of the pressure reduction segment in the water flow direction. The piston is located at the throat portion of the throat pipe opening. One end of the spring is connected with the fixing arm, and the other end of the spring is connected with the piston. The throat portion of the throat pipe opening and the front end of the piston form a matching face for driving the piston to close the throat portion of the throat pipe opening under the action of the spring. Compared with the prior art, high-pressure water supply can be changed into flow-adjustable low-pressure water supply, the risk that the domestic tap water pipes and auxiliary pipes are cracked due to overly-high pressure, and the pressure reduction device is remarkable in pressure reduction effect, concise in structure, low in cost, suitable for being applied to arrangement of domestic tap water pipes and wide in popularization range.

Description

technical field [0001] The present invention is a household tap water pipe decompression device designed for current household tap water pipes and accessory pipe fittings which are easily cracked due to high pressure. It belongs to the technical field of civil building water supply and drainage. Background technique [0002] In the current part of the water supply pipeline for civil buildings, due to factors such as high-pressure water supply and the material of the water pipe itself, the household tap water pipe and its auxiliary pipe fittings are prone to rupture. Technology is deficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to invent a kind of domestic water pipe decompression device for the above-mentioned deficiencies in the prior art. The blunt body boundary formed by the spring reduces the energy of the water flow and reduces the pressure of the water flow, so as to reduce the water pressure on the house...
