Description
The asynchronous interlock water temperature of gas instantaneous water heater air-water is transferred device, belongs to fuel gas buring and applied technical field.
The water temperature regulative mode of all gas instantaneous water heaters in the market has following several:
1. water, gas are distinguished regulative mode.Separate water valve and air valve all are provided with adjusting
Handle (wheel) generally speaking, is regulated water with the method for regulating air valve opening
Temperature when the air valve standard-sized sheet, if water temperature does not still reach requirement, is regulated water valve again,
Reduce discharge, this method complicated operation and brought for the structural design of water heater
Trouble;
2. air-water interlock regulative mode.By same regulating handle (wheel) regulate air valve and
Water valve, two control valves, two gears engaged wherein, adjusting is synchronous, promptly opens
Water valve then turns down during atmos-valve, and this mode has increased the sensitivity of regulating, but
Cross at hydraulic pressure and to occur the too small phenomenon of water yield easily when low, even make water heater
Cisco unity malfunction seldom adopts at present;
3. computer control ratio valve regulation mode.This mode is only to regulate tolerance equally,
And when the low and water yield of inflow temperature in winter is big, can not satisfy that water temperature regulates
Requirement need be regulated the flow of water valve equally with other modes;
4. computer fuzzy control stepper motor regulative mode.This mode is just regulated air valve
The method difference, its deficiency is basic identical with 3;
5. line traffic control regulative mode.This method and 1 difference, adopt exactly two common
Machine is line traffic control water valve and air valve respectively, to replace operating grip (wheel).
In view of above 5 kinds of regulative modes are all not enough to some extent, can not move with same adjusting exactly and realize the water temperature adjusting, especially in the full-automatic water heater thermostatic control system, this defective more can not be ignored.
The purpose of this utility model is to make the water temperature of gas heater regulate more simple, convenient and science.With the handle (wheel) (8) in the coaxial cock (3) that is installed in the air valve (21), regulate the aperture of air valve, when the approaching maximum of air valve opening, continue rotary handle (8), its rotation is passed to driven gear (9) by coaxial mounted driving gear (7), gear (9) and the coaxial installation of cock for water valve (10), its servo-actuated and turning down, and do not need to be provided with separately in addition and operation water valve regulating handle (wheel).
The utility model adopts gear drive to regulate gas, discharge, driving gear (7) and driven gear (9) are special hypodontia sector gear, its handle (wheel) (8) and driving gear (7) and the coaxial installation of air valve cock (3), driven gear (9) and the coaxial installation of cock for water valve (10), gear (7) can intermesh after rotation is adjusted to certain angle with the tooth position that has of gear (9), the axis of the cock (10) of water valve (15) and the cock (3) of air valve (21) is parallel to each other, the maximum anglec of rotation of gear (7) is (C), the maximal regulated angle of water valve is (D), and be provided with two alignment pins (12), initial installation site at gear (7) and gear (9), air valve (21) is in minimum aperture, and water valve (15) is in full-gear, constitutes the asynchronous interlock water temperature regulation device of gas instantaneous water heater air-water.When water temperature is low need heighten water temperature the time, counter-clockwise rotary handle (8), adjusting initial stage, gear (7) does not mesh with gear (9), and this moment, the aperture of air valve became big, and water valve is failure to actuate, the aperture of water valve still is maximum, if need continue to heighten water temperature, then only need to continue rotary handle (8), in the aperture of air valve during near standard-sized sheet, gear (7) and gear (9) engagement, gear (9) drive cock for water valve (10) turns clockwise and turns down water valve, and water temperature continues to heighten, and the maximal regulated angle that turns down water valve is (D).Only establish a regulating handle (8), be connected spool (3) and spool (10) with gear (9), the aperture of air valve (21) and water valve (15) is carried out asynchronous interlock regulate by special gear (7).
The asynchronous interlock adjusting device of the utility model is by gas control valve (21), water regulating valve (15), and hypodontia sector gear (7), handle (wheel) (8), sector gear (9) constitutes, and its adjusting process is as follows:
1. as Fig. 2, when water heater is started working, combustion gas enters the fuel gas inlet (2) of cock (3) in the valve by the fuel gas inlet (1) of air valve (21), and the outlet (23) that enters gas valve (21) by the gas outlet (22) in the air valve cock (3) is to the burner of gas heater; The import (19) that current enter cock for water valve (10) from the water inlet (20) of water valve (15) by the water out (18) of the water out (17) in the cock (10) to the water valve (15), enters the heat exchanger of water heater.
2. as Fig. 3, the initial installation site of adjusting device, the hard-over of gear (7) is (C), its size is by alignment pin (12) control that is located on the water valve, the hypodontia angle of its sector gear (7) is (A), (see figure 1), and the unfilled corner of gear (9) is (B), (see figure 1), during initial the installation, water valve (15) standard-sized sheet, the aperture of air valve (21) is minimum, the determined value at angle (A) is the anglec of rotation of air valve during near standard-sized sheet, in initial state,, on the low side as water temperature if open water heater, in the time of need heightening water temperature, then counter-clockwise rotary handle (wheel) (8), during rotational angle (A), (see figure 4), because gear (7) and gear (9) do not mesh, water valve (15) is not done adjusting, if water temperature reaches requirement, and its device relative status such as Fig. 4, water temperature as this moment is still not enough, then continue counter-clockwise rotary handle (wheel) (8), gear (7) and gear (9) engagement this moment, gear (7) driven gear (9) turns clockwise, promptly turn down water valve (15), (as Fig. 5).When if the too high need of water temperature are turned down, the handle (wheel) (8) that then turns clockwise is as gear this moment (7) and gear (9) engagement, then water valve leaves greatly, and air valve turns down, up to gear (7) with after gear (9) separates, air valve continues to turn down, and water valve no longer moves, and the maximal regulated angle of water valve is (D).
3. this device is when realizing its purpose, the fan-shaped unfilled corner (A) of air valve anglec of rotation gear (7) during near standard-sized sheet and the hard-over (C) of gear (7) are key parameter, it has determined the fan-shaped unfilled corner (B) of gear (9) and the maximal regulated angle (D) of water valve, now illustrate: if the A=90 degree, the C=180 degree, D=C-A=180-90=90 degree then, the B=360-D=360-90=270 degree, the actual value of B should be worth little than this.
Advantage of the present utility model and effect:
1. only use a regulating handle (wheel) that air valve and water valve are carried out asynchronous interlock adjusting,
Make the water temperature of gas instantaneous water heater regulate more simple, practical and reliable;
2. the utility model can overcome the deficiency of existing water temperature regulative mode, water heater water outlet
The adjusting of temperature is not subjected to the influence of hydraulic pressure and flow of inlet water;
3. the water that can be used for common water heater, fully-automatic thermostatic water heater and line traffic control water heater
Temperature controlling system.
