Abstract
The utility model belongs to a solar energy water heater, in particular to a solar water heater of preventing the water supply-drainage pipeline from blocking by freezing. The vertical and upward end of a triplet in a thermal insulation water tank assembly is connected with a one-way valve and an evacuation pipe, and the tail end of an evacuation control pipeline is connected with an evacuation control valve. The machinery mode is adopted totally in the evacuation action and the control elements; the evacuation action elements and the thermal insulation water tank of the solar energy water heater constitute the integration, and the mechanism control mode is adopted to complete the evacuation action. Consequently, the utility model solves the problem that in the winter, the pipeline used in the solar energy water heater is frozen.
Description
Technical field the utility model belongs to apparatus for heating water by solar energy, particularly relates to a kind of novel upper and lower conduit road frozen-plug type solar water heater that prevents.
Background technology is traditional prevents that solar water heater's upper and lower conduit road from freezing stifled method is to adopt beyond solar water heater's main frame upper and lower conduit head place to install annexes such as micro machine exhaust-valve or electromagnetism exhaust-valve additional to finish the water-supply pipeline evacuation task, because air emptying function only uses in the winter time, on the shelf At All Other Times, so the probability that the control element of micro machine exhaust-valve or electromagnetism exhaust-valve breaks down is high; In addition, micro machine exhaust-valve or electromagnetism exhaust-valve are installed in beyond solar water heater's main frame with the auxiliary form, because construction condition was limit when the solar water heater was installed, the valve body part of micro machine exhaust-valve or electromagnetism exhaust-valve can only be carried out simple process by the mode of general pipe insulation, in the coldest while in every year also is to need most in the season of using tube emptying, its valve body is often owing to freezing to make the akinesia of emptying action element, air emptying function can't realize that the pipe freezeup problem can not be solved at all.
The summary of the invention the purpose of this utility model provides a kind of novel upper and lower conduit road frozen-plug type solar water heater that prevents, emptying action and control element all adopt mechanical system, emptying action element and solar water heater's attemperater manufacture an integral body and adopt mechanical control method to finish the emptying action, solve the solar water heater and use the pipe freezeup problem winter.
The purpose of this utility model is achieved in that a kind of novel upper and lower conduit road frozen-plug type solar water heater that prevents, is made up of attemperater assembly, upper and lower conduit road, and the threeway in the attemperater assembly of being chatted is held vertically downward and is connected with upper and lower conduit; Threeway is held vertically upward and is connected with check valve, evacuated tube, and evacuated tube is connected with emptying control pipeline, and emptying control pipe end is connected with the emptying control valve; The threeway horizontal ends is connected with upper and lower conduit, and upper and lower conduit passes heat-insulation layer, end socket is connected with the upper and lower conduit road, and upper and lower conduit road end is connected with threeway, and an end of threeway connects cold water control valve, and the other end connects the hot water control valve.
The upper and lower conduit of being chatted is plugged into bottommost from the top of inner bag.
The threeway of being chatted, check valve are preset between inner bag and the shell also with manufacturing an integral body with attemperater behind the polyurethane insulation material integral foam.
The threeway of being chatted, check valve both can two elements the independent setting of form also can manufacture an integral body.
The utility model is compared with prior art: the novel emptying action element that prevents upper and lower conduit road frozen-plug type solar water heater is preset between inner bag and the shell and with being incubated behind the polyurethane insulation material integral foam, has solved to freeze the problem that can not realize that emptying is moved cold season because of the exhaust-valve action element; Adopt mechanical control element control emptying action, solved the problem of the high fault rate of electrical type control element of using seasonal intermittence and causing.
Description of drawings is further specified the utility model below in conjunction with description of drawings.
Fig. 1 is the novel upper and lower conduit road frozen-plug type solar water heater structural representation that prevents.
In the accompanying drawings, 1 be inner bag, 2 for shell, 3 for heat-insulation layer, 4 for upper and lower conduit, 5 for end socket, 6 for threeway, 7 for check valve, 8 for evacuated tube, 9 for emptying control pipeline, 10 for upper and lower conduit, 11 for the emptying control valve, 12 for the upper and lower conduit road, 13 for cold water control valve, 14 for threeway, 15 be the hot water control valve
Threeway (6) in this novel attemperater assembly that prevents upper and lower conduit road frozen-plug type solar water heater of the specific embodiment is held vertically downward and is connected with upper and lower conduit (4); Threeway (6) is held vertically upward and is connected with check valve (7), evacuated tube (8), evacuated tube (8) is connected with emptying control pipeline (9), emptying control pipeline (9) end is connected with emptying control valve (11), open emptying control valve (11), under the effect of atmospheric pressure, check valve (7) will be opened, threeway (6), water in the upper and lower conduit (4) will be back in the inner bag (1), open hot water control valve (15), upper and lower conduit (10), water in the upper and lower conduit road (12) will all flow out, thereby guarantee that upper and lower conduit road (12) is anhydrous, finish upper and lower conduit road (12) emptying task; Threeway (6) horizontal ends is connected with upper and lower conduit (10), upper and lower conduit (10) passes heat-insulation layer (3), end socket (5) is connected with upper and lower conduit road (12), upper and lower conduit road (12) end is connected with threeway (14), one end of threeway (14) connects cold water control valve (13), and the other end connects hot water control valve (15).
This novel upper and lower conduit (4) that prevents upper and lower conduit road frozen-plug type solar water heater is plugged into bottommost from the top of inner bag (1), opens hot water control valve (15), because the effect of siphon and potential energy, the hot water in the inner bag (1) will automatically spray.
This novel upper and lower conduit road frozen-plug type solar water heater's threeway (6), the check valve (7) of preventing is preset between inner bag (1) and the shell (2) also with manufacturing an integral body with attemperater behind the polyurethane insulation material integral foam.
This novel threeway (6) that prevents upper and lower conduit road frozen-plug type solar water heater, check valve (7) both can two elements the independent setting of form also can manufacture an integral body.
