Problems solved by technology

[0002] For example, the Chinese patent 2008201006626 "instant water-saving solar water heater" declared by me is a traditional type of water heater with straight pipe installation, which has requirements and restrictions on construction requirements and installation environment, which narrows its scope of use, and the pipes are exposed on the wall. It is not safe and not beautiful; when it is turned on and used, the pipe is filled with cold residual water and cannot be heated, and all the cold water in the sewer pipe must be drained before hot water can flow out, especially when the water heater is used in the cold north It shows its disadvantages, the remaining water in the pipe is often frozen and cannot be used, it wastes increasingly tense water resources, and also increases the difficulty and cumbersome use, which is not convenient and practical; the existence of electric equipment in the installation of water heaters is safe. trapped

Embodiment 1

[0020] See figure 1 , The water pressure emptying device of the solar water heater includes a three-way pipe-type emptying valve host 2 and an exhaust valve 3 at the water outlet of the water tank 1, and the other water pipe of the emptying valve host 2 is connected to the mixed water through the automatic regulating valve 4 valve 5.

[0021] The main engine 2 of the emptying valve is a three-way pipe, and a push rod I 21 is set in the linear pipe. The two ends of the push rod I 21 are respectively provided with locks I 22, and then inserted into the center hole of the fixed leaking plate I 23, and the fixed leaking plate I 23 at both ends The piston I 24 is pushed centrally through the n-seal port 25 . When angle valve 6 was closed, open and close water tap 11 simultaneously. The push rod I 21 moves down until the upper piston I 24 is closed and automatically empties; when the angle valve 6 is opened, the bottom piston I 24 push rod I 21 moves up to open the upper piston I ...

Embodiment 2

[0024] See figure 2 ,

[0025] A three-way pipe-type emptying valve host 2 and an exhaust valve 3 are arranged at the water outlet of the water tank 1, and the other water pipe of the emptying valve host 2 is connected to the water mixing valve 5 through the automatic regulating valve 4. Due to the needs of interior decoration or site, when the circulation pipe is designed to make a sharp turn, such as "U", "V", etc., it is necessary to install it between the automatic regulating valve 4 and the mixing valve 5, that is, on the elbow. The U-shaped water processor 8 and the U-water automatic valve 9 are used together. An n-type floating plug 82 with a floating plug 81 is arranged in the U-shaped water processor 8, and a three-channel pipe connecting elbow is arranged above the floating plug 81. On the main pipeline, a residual water level switch 83 is arranged in the floating plug post 81, the central hole below is the residual water outlet, and a residual water level regulati...

Abstract

The invention relates to a water pressure emptier of a solar water heater. A water heater with the traditional straight pipe installation mode has requirement and limit on construction and installation environment. The remaining water in a pipeline needs to be emptied and then heating is available. In the north, the remaining water tends to be frozen and is unavailable to use, thus wasting resources and hiding potential safety troubles in the presence of electric equipment. A water outlet of a water tank is provided with a vent valve main frame of a three-way pipe type and an air evacuation valve; and another water pipe of the vent valve main frame is connected with a water mixing valve through an automatic adjusting valve, and a U-shaped water treating device and a U-shaped water automatic valve are also between the automatic adjusting valve and the water mixing valve, namely on a bent pipeline. The emptier does not need power and once turned on, hot water is available. The emptier thoroughly empties the indoor remaining water in U shape, does not change the original structure and has the advantages of wide application range, safe and reliable properties, water and energy saving, antifreeze and pragmatic properties, longer service life, convenient modification, low cost, simple and easy operation and the like.

Description

technical field [0001] The invention relates to an energy-saving antifreeze product, in particular to a water pressure emptying device for a solar water heater. Background technique [0002] For example, the Chinese patent 2008201006626 "instant water-saving solar water heater" declared by me is a traditional type of water heater with straight pipe installation, which has requirements and restrictions on construction requirements and installation environment, which narrows its scope of use, and the pipes are exposed on the wall. It is not safe and not beautiful; when it is turned on and used, the pipe is filled with cold residual water and cannot be heated, and all the cold water in the sewer pipe must be drained before hot water can flow out, especially when the water heater is used in the cold north It shows its disadvantages, the remaining water in the pipe is often frozen and cannot be used, it wastes increasingly tense water resources, and also increases the difficulty ...
