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

Water pressure emptier of solar water heater

Technical field

The present invention relates to a kind of energy-conservation anti-freezing product, relate in particular to a kind of water pressure emptier of solar water heater.

Background technology

The Chinese patent of declaring as me 2008201006626 " instant heating water-saving type solar water heater " is the water heater of the straight tube mounting means of traditional type, construction requirement and installation environment there are requirement and restriction, dwindled its scope of application, pipeline is exposed to metope, and is dangerous also not attractive in appearance; When opening use, the pipeline inner product has expired ice-cold surplus water and can't heat, after must having got rid of whole cold water of sewer pipe, hot water can flow out, more show its shortcoming especially when water heater uses in the north of cold, the surplus water in the pipe often can't be used by freezing, and it has wasted the waterpower resourses of growing tension, also increased the difficulty used and loaded down with trivial details, inconvenient practical; During installing, water heater have the existence of electric equipment just to have sunken safely suffering from.

Summary of the invention

The present invention is directed to above-mentioned deficiency, provide, have water saving without power supply, energy-conservation, antifreeze, safety, practical, increase the service life, one opens hot water is promptly arranged, and also thoroughly solves the water pressure emptier of solar water heater of the surplus water of indoor U-shaped.

The present invention adopts following technical proposal to realize for achieving the above object:

Exhaust-valve main frame, the air bleeding valve of threeway tubular type are set at the water outlet of water tank place, and another branching pipe of exhaust-valve main frame connects mixed water valve by automatic regulating valve;

The exhaust-valve main frame is a three-way pipe, and push rod I is set in rectilinear tubes, and interspersed fixedly leaking coiled the centre bore of I after the two ends of push rod I were provided with snap close I respectively, and the dish I that fixedly leaks at two ends is by n type seal center contact piston I;

Automatic regulating valve is the threeway tubular type, and the seal of intermediate openings is set above the intersection in straight tube, and piston I II places the seal below.

U-shaped hydrotreater and U water automatic valve are set between automatic regulating valve and the mixed water valve;

The n type floating plug of a band floating plug post is set in the U-shaped hydrotreater, and the top of floating plug post is provided with on the trunk line of threeway deferent bridge piece, be provided with one in the floating plug post surplus water level switch, the below centre bore is surplus water out, floating plug post top is provided with surplus water level control apparatus.

In the U water automatic valve push rod II is set, interspersed fixedly leaking coiled the II centre bore after the two ends of push rod II were provided with snap close II respectively, and wherein the dish II that fixedly leaks of an end is by n type seal center contact piston II, and the other end connects piston I I and spring.

Surplus water level switch is a triangle.

Water pressure emptier of solar water heater is omnidistance for there not being the electrification design, and the use of exhaust-valve utilizes the surplus water in the animal physics and chemistry ground emptying water pipe of moving down of push rod, does not need electrical actuation power source, and is safer energy-conservation in the use; Prolonged service life, for the unimpeded of next hot water lays the foundation; When being used for the north, temperature is down to zero following when icing, and empty outlet conduit also can normally use not by freezing.Saved the water source, the convenient use.

Since the existence of U type processor and U type automatic valve, the path diversification of installation, can directly can bend can be bent, and being suitable for different constructions and place needs, and pipeline can be embedded under the indoor floor, more beautifies living environment;

This water pressure emptier of solar water heater is applicable to multiple water heaters such as solar energy, electric energy or combustion gas.Do not change original structure, applied widely, safe and reliable, repacking is convenient, cost is low, simple.
