Description
Technical field
The utility model relates to a kind of temperature control unidirectional stop valves more particularly to a kind of energy available energy to prevent cold water pipe and hot water
The self-supporting temperature control unidirectional stop valve of pipe string water.
Background technique
Has instant-heating formula water heater on the market at present, the basic principle is that increasing on the pipeline in common water heater
Add a water pump, using hot water cooling in water pump circulating hot water pipe, to trigger water heater starting heating, realizes pipeline " zero
The function of cold water ".
Currently, the common hot water circulating device for being matched in gas heater on the market, and using principle as above into
Row work, difference are: by hot water circulating device independently of water heater.Hot water circulating device installation, in terms of more
Flexibly, it is able to achieve and original common hot-water heating system is transformed into the instant-heating circulatory system, and do not have to purchasing price valuableness zero is cold
Hydro-thermal hydrophone (instant-heating water heater).
It, can be by manual or reservation function or distant regardless of the instant-heating hot water cyclesystem that mode forms
The modes such as control start, and the water in pipeline are heated to set temperature in advance, but all there is deficiencies.If user's selection is opened manually
Dynamic or remote control starting then has to wait for allowing pipeline to complete preheating for a period of time, and the experience of instant-heating function is affected.And such as
Fruit uses reservation function, guarantees instant-heating within the selected period, then to the peace of the temperature sensor in hot water circulating device
Holding position requires, and the end for being mounted on hot water line is clearly optimal selection, but in fact, due to distance and structure limit
System, for temperature sensor in cold water pipe either return pipe, these places not can truly reflect hot-water line in most cases
The temperature regime on road, will cause the error starting of circulator, to cause the frequent starting of water heater, reduce the water heater service life,
And cause a large amount of wastes of the energy.
For the user fitted up especially for the house largely without water return pipeline, if temperature sensor is arranged in
In cold water pipe, when starting using reservation protocol, not only will cause water heater frequent starting, also will cause hot water in hot-water line into
Enter into cold water pipe, no cold water is available, and the water in cold water pipe can also be made to generate peculiar smell.For being mounted with the user of purifier
For, or even purifier can be damaged.
To solve the problems, such as to exist using temperature sensor, temperature is replaced using thermostat valve (having self-operated type, electrodynamic type)
Control sensor, with overcome water heater frequent starting or without cold water can with the case where occur.But existing thermostat valve again there is
Structure is complicated, and the high problem of cost limits widespread adoption of the thermostat valve in hot water cyclesystem.
Summary of the invention
A kind of self-supporting temperature control list is provided utility model aims to solve the above problem of the existing technology
To shut-off valve, in use, being arranged in hot water pipe end, it can be avoided the hot water in hot-water line and seal in cold water pipe, and can lead in real time
Superheated water pipe end temperature opens or closes shut-off valve, avoids water heater frequent starting, and structure is relatively easy, at low cost,
Energy conservation and environmental protection again.
What the above-mentioned technical purpose of the utility model mainly solved by the following technical programs: self-supporting temperature control is unidirectionally cut
The spool in the main valve body and being located in the fluid channel, institute is arranged in including the main valve body with fluid channel in only valve
One end setting sealing element of spool is stated, returning spring is arranged in the other end of the spool, and the sealing element is logical close to the fluid
The water inlet in road, when the spool closes said fluid channel, the sealing element and the main valve body form sealing cooperation, special
Sign is that one temperature sensing package of one end fits of the returning spring is arranged on the spool, when temperature reaches setting value, the sense
Thermometer bulb expansion pushes the spool mobile to the water inlet end of the fluid channel, so that the spool is closed the fluid logical
Road, for ending water flow；When temperature is lower than setting value, the temperature sensing package is shunk, and the hydro-flow thrust on the spool is greater than described
Temperature sensing package acts on the summation of the power of the spool and the elastic force of the returning spring, separates the sealing element and main valve body,
Realize water flow one-way flow.Using in hot water circulating pipeline, the water outlet of main valve body connects cold water pipeline, the water inlet of main valve body
The end of mouth connection hot-water line, temperature sensing package experience water flow temperature, spool are made to close fluid channel in time, can be avoided in hot-water line
Hot water seal in cold water pipe.And the end of hot-water line is arranged in shut-off valve, then can be made according to real time temperature shut-off valve open or
It closes, water heater is avoided frequently to malfunction, be conducive to protect water heater.In addition, shut-off valve has check valve and thermostat valve simultaneously
Function, simplify product structure, reduce costs.Moreover, the complete self-operated type of the self-supporting temperature control valve member course of work, is not necessarily to it
The supply of its additional energy source, environmental protection and energy saving.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures: in order to
So that temperature sensing package is moved axially, a guide holder is fixedly installed in the valve body, guide post is provided on the guide holder, it is described
Pilot hole is set in guide post, a plurality of throughbores are set on the guide holder, one end of the temperature sensing package passes through described lead
Xiang Kong simultaneously has extended segment, and the pilot hole is for making the temperature sensing package along the axial movement of the main valve body.The extension of formation
Section is to be able to preferably form cooperation with spool and returning spring, is also beneficial to simplify guide seat structure.It is logical that water flow is set
Hole is to keep water stream channel unimpeded.
The temperature sensing package is axially arranged away from one end of spool setting protection spring, the protection spring, the guarantor
The one end for protecting spring contradicts in the temperature sensing package, and the other end contradicts on the main valve body or pipe fitting, when the fluid is logical
In road when the temperature is excessively high, the temperature sensing package is mobile to the protection spring direction, the protection spring is compressed, to protect institute
Temperature sensing package is stated to avoid damaging with main valve body generation extruding.
One mandril is set between the temperature sensing package and spool, and the mandril is fixed on the spool.Temperature sensing package is heated swollen
It is swollen or contract on cooling and generate corresponding power or displacement be then transmitted on spool by mandril, so that spool is closed or opened water in time
Circulation road.
