Abstract

The utility model relates to a water saving device of a hot water supply pipeline, which is used for a hot water supply system. The device comprises a hot water inlet pipe connected with a hot water system such as a hot water heater, and the like, and a cold water inlet pipe connected with a cold water pipeline, and the intersection of the hot water inlet pipe and the cold water inlet pipe is provided with a mixing valve used for adjusting the outlet water temperature; the water outlet part of the mixing valve is connected with a water outlet pipe, the outlet water of the water outlet pipe is connected with two paths of branches through a flow direction valve, wherein one path of branch is communicated with a water using outlet, and the other patch of branch is connected into a water tank through a section of circulating water inlet pipe; a water level control valve controlled by the water level in the water tank is mounted on the cold water inlet pipe; and the water tank is also connected with a circulating water outlet pipe used for outputting water, and the circulating water outlet pipe is led to the cold water inlet pipe arranged between the mixing valve and the water level control valve through a one-way valve. The utility model can take full advantage of the cold water remained in the hot water inlet pipe so as to avoid waste.

Description

Hot water feeding pipe road water saving fixtures

Technical field

The utility model relates to a kind of hot water feeding pipe road water saving fixtures that are used for hot water supply system.

Background technology

Common hot water feeding pipe road generally comprises the hot water oral siphon that is connected with hot-water heating systems such as water heaters and is connected the cold water oral siphon with the cold water pipeline, the intersection of hot water oral siphon and cold water oral siphon is provided with the mixing valve that is used for adjusting coolant-temperature gage, and the water that passes through mixing valve directly leads to the usefulness water out (as tap or gondola water faucet etc.) that uses for the user.The pipeline of this structure is detained in the hot water oral siphon between hot-water heating system and the mixing valve before use one section cold water, the hot water that the hot-water heating system of can making a profit after need waiting this section cold water all to discharge when just beginning heat supply water is sent here, so just cause the significant wastage of water resource, particularly hot-water heating system with water end (W.E.) when at interval far away, this waste is just more outstanding.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of hot water feeding pipe road water saving fixtures that can make full use of the cold water that is trapped in the hot water oral siphon, the water source that avoids waste in the hot water feeding pipe.

Hot water feeding pipe of the present utility model road water saving fixtures include the hot water oral siphon that is connected with hot-water heating system such as water heater and are connected the cold water oral siphon with cold water pipes, and the intersection of hot water oral siphon and cold water oral siphon is provided with the mixing valve that is used for adjusting coolant-temperature gage; The water part of mixing valve is connected with outlet pipe, and the water outlet of outlet pipe connects two-way branch through flow valves, flow valves can two-way branch between switching water discharging flow to; Wherein one tunnel branch leads to and uses water out, and another road branch is connected in the water tank through one section circulation water inlet pipe; One be installed on the cold water oral siphon by the altitude valve of water tank middle water level control; Also be connected with on the water tank and be used for the recycling outlet of water outlet, recycling outlet leads to cold water oral siphon between mixing valve and the altitude valve through a check valve.Described altitude valve can be a ball-cock assembly.

The utility model in use can be stored in the water tank and mixes use subsequently with hot water being trapped in cold water in the hot water oral siphon, thereby has made full use of the water source, has avoided putting the waste that causes owing to being detained the cold water sky.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

The each several part mark is as follows in the accompanying drawing: hot-water heating system 1, hot water oral siphon 2, cold water oral siphon 3, mixing valve 4, outlet pipe 5, flow valves 6, usefulness water out 7, circulation water inlet pipe 8, water tank 9, altitude valve 10, recycling outlet 11, check valve 12, cold water pipes 13.

As shown in the figure, the course of work of the present utility model is as follows: when beginning heat supply water, flow valves 6 switched to open circulation water inlet pipe 8, close position with water out 7, simultaneously mixing valve 4 is adjusted to the hot water standard-sized sheet, the state of cold water complete shut-down, be trapped in the cold water process outlet pipe 5 in the hot water oral siphon 3 this moment, flow valves 6 and circulation water inlet pipe 8 enter water tank 9, after after a while, the cold water that is detained all is injected in the water tank, and the rising of water tank middle water level also makes altitude valve 10 close (be embodied in the ball float that is ball-cock assembly in the accompanying drawing illustrated embodiment float and close); After the cold water that is detained enters water tank, flow valves 6 switched to open with water out 7, close the position of circulation water inlet pipe 8, just can deliver to water out 7 from the hot water of hot-water heating system, at this moment altitude valve 10 is in closed condition, cold water in the outside cold water pipes 13 can't enter mixing valve 4 by cold water oral siphon 3, and the cold water that stores in the water tank then can enter the cold water oral siphon and enter mixing valve and mix the adjusting water temperature with hot water by check valve 12; After water in water tank had flowed, altitude valve 10 reopened, and the cold water in the at this moment outside cold water pipes 13 just can enter cold water oral siphon 3 and use for mixing valve mixing temperature adjustment.

Claims

1, a kind of hot water feeding pipe road water saving fixtures, include hot water oral siphon (2) that is connected with hot-water heating system (1) and the cold water oral siphon (3) that is connected with cold water pipes, the intersection of hot water oral siphon and cold water oral siphon is provided with the mixing valve (4) that is used for adjusting coolant-temperature gage, it is characterized in that: the water part of mixing valve is connected with outlet pipe (5), the water outlet of outlet pipe connects two-way branch through a flow valves (6), wherein one tunnel branch leads to water out (7), and another road branch is connected in the water tank (9) through one section circulation water inlet pipe (8); One be installed on the cold water oral siphon (3) by the altitude valve (10) of water tank middle water level control; Also be connected with on the water tank and be used for the recycling outlet (11) of water outlet, recycling outlet leads to cold water oral siphon (3) between mixing valve (4) and the altitude valve (10) through a check valve (12).
