Description
Technical field
The present invention relates to Heating, Ventilation and Air Conditioning (HVAC) Technology field, specifically a kind of H types return water system intelligent temperature control valve.
Background technology
At present mainly hot water circuit confession is carried out in the pipe network system of household water by way of water flow switch adds circulating pump
Should, following two problems be present in aforesaid way：1st, the toilet from water heater distalmost end is generally required to wait and remained in hot-water line
Water at low temperature discharge after just have hot water；2nd, the berthing time that opens of the circulatory system is set, and the setting of time is manually to survey
It is fixed, error inevitably be present, and such error frequently can lead to hot water and enter in cold water pipe, cause user to scald thing
The generation of part.
As shown in figure 1, being the schematic diagram of existing domestic hot water's circulatory system, it forms and its act as substantially：(1) hot water
Device, there is provided thermal water source；(2) temperature control loop control box, mainly by circulating pump and corresponding circuit board group into as hot water circuit system
The power source of system circulation；(3) water flow switch, the current conditions in pipeline is converted into switching regulator electric signal transmission and circulated to temperature control
Control box, to reach opening/stopping for the control circulatory system；(4) check valve, control current, can not along the single direction flowing specified
Reverse flow；(5) hot water main pipe road, the conveyance conduit of hot water supply；(6) cold water main pipe road, the conveyance conduit of cold feed.
The general principle of existing domestic hot water's circulatory system：
As shown in figure 1, current domestic hot water's circulatory system will realize that the master of distalmost end defends and use hot water, it is to be beaten by user
Turn on the tap and close after the 2-6 seconds, water flow switch is sensed the streamflow regime in pipeline, water flow switch again converts streamflow regime
Temperature control loop control box is transferred to for open signal, temperature control loop control box starts circulating pump, and the work by setting in advance
Make the time is transported to the master of farthest by hot water and defends on time, when reach the working time is set when, circulating pump is stopped.And temperature control
The working time of set circulating pump manually determines in advance in loop control box.Continuous mode needs first to open main defend
Tap, measure hot water from water heater to master defend the required time, the time of measure is then input to temperature control loop control box
In, to reach the purpose of control circulation pump operation time.The problem of existing domestic hot water's circulatory system is present：Temperature control loop control
The minute inputted in box is labor measurement, error inevitably occurs, the normally about 5-10 seconds are very normal, Er Qiere
Water is responsible for cold water main pipe joint without the effective management and control of temperature-sensing valve, then the error time of 5-10 seconds most likely results in two kinds of knots
Fruit：One kind is stopped to setting time, circulating pump, but the master that hot water actually has not arrived farthest defends, and causes to lead
Hot water can not be gone out in time by defending；Another situation is exactly that the operating of circulating pump time-out causes hot water being delivered directly in cold water pipe,
The so main moment water outlet defended will be all hot water, it is possible to scald user.
The content of the invention

Prevent current by the gap leakage between the second t-joint 19 and main valve body right side.
As shown in Fig. 2 the operation principle of H type return water system intelligent temperature control valves is：
When hot water in hot water main pipe road passes through the temperature-sensing valve, when the water flow temperature rise in the second t-joint 19,
Thermometer bulb expanded by heating, the push rod 171 in thermometer bulb 17 is extended, promote small end motion of the seal assembly towards fixed seat 10, until
Sealing gasket 12 is fixed the small end end face of seat 10, and now temperature-sensing valve is closed；Otherwise when the water flow temperature for flowing through thermometer bulb 17 reduces
When, its internal paraffin shrinks, while push rod 171 also shortens therewith, and seal assembly is gradually remote in the presence of the first spring 13
From the small end of fixed seat 10, temperature-sensing valve is gradually opened, while check valve 2 is opened under hydraulic pressure effect, current is referred to along arrow
Show that direction is flowed.
Operation logic of the H type return water system intelligent temperature control valves in family's hot water cyclesystem：
As shown in Fig. 2 to realize that the master of distalmost end defends uses hot water, and closed after opening the tap 2-6 seconds by user
Close, water flow switch is sensed the streamflow regime in pipeline, streamflow regime is converted into open signal again and is transferred to by water flow switch
Temperature control loop control box, temperature control loop control box start circulating pump, but different from common existing domestic hot water's circulatory system
It is：Due to the water temperature≤temperature-sensing valve remained in the distalmost end master place of defending hot-water line opening temperature when, temperature-sensing valve is opened, in hot-water line
The water at low temperature of residual is withdrawn into water heater and reheated by temperature-sensing valve and the cold water main pipe road being attached thereto, while hot water
The master that hot water in device also flows to farthest in time defends, when hot water flows through H type return water system intelligent temperature control valves, due to hot water water
The closing temperature of warm ＞ H types return water system intelligent temperature control valve, so now temperature-sensing valve is closed, hot water is directly entered the master of farthest
In the hot-water line defended, user is set to enjoy warm hot water in time.
The advantages of H type return water system intelligent temperature control valves that the invention provides are in family's hot water cyclesystem：(1) without multiple
It is miscellaneous and less correct time determines, connect and can be used, installation and debugging are convenient, simple；
(2) intelligent temperature control function, securely and reliably, effectively avoid hot water from entering in cold water pipe, prevent user from opening tap
Scalded during use；
(3) the complete self-operated type of the course of work, supplied without other additional energy sources, environmental protection and energy saving.
