Description
Technical field
The present invention relates to plumbing, more particularly to a kind of coaxial double-control thermostatic valve element adjusting handle.
Background technology
Thermostatic valve is the main control part inside constant-temperature water faucet.Existing coaxial double-control thermostatic valve element can be realized simultaneously
Control for temperature and the control for water flow, greatly simplify the overall structure of constant-temperature water faucet.
As shown in figure 1, coaxial constant temperature dual control valve element generally comprises upper valve body 11, valve seat 12 and base 15, upper valve body 11 is pacified
In valve seat 12 and base 15, the thermoregulation knob 14 for temperature adjustment is installed, between valve seat 12 and base 15 in upper valve body 11
Water-quantity regulating device is installed.Upper valve body 11 can occur unitary rotation relative to valve seat 12, base 15, when rotation upper valve body 11
When, the water yield of the coaxial double-control thermostatic valve element changes.The top of thermoregulation knob 14 is stretched out from the end of upper valve body 11, works as rotation
During the end of thermoregulation knob 14, thus it is possible to vary the leaving water temperature of the valve element.
Existing constant temperature valve core adjusting handle structure design is unreasonable, it is impossible to preferably adapts to coaxial double-control thermostatic valve element and adjusts
The regulation of water temperature and water yield needs.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of coaxial double-control thermostatic valve element regulation hand
Wheel, energy structure is relatively simple, can more conveniently realize the regulation for water temperature and water yield.
Above-mentioned technical purpose of the invention technical scheme is that：A kind of coaxial double-control thermostatic valve element
Adjusting handle, including runoff investigation wheel and lower water temperature wheel, the runoff investigation wheel are set in upper valve body outside and and upper valve body
Drive connection, lower water temperature wheel be set in striated knob outside and with thermoregulation knob drive connection, the lower water temperature wheel and water
Spring cavity and multiple stopper slots are respectively arranged between amount left regulation wheel, spring are provided between stopper slot and spring cavity and by spring
Drive and keep head to be in the locating piece in stopper slot, positioning block header is spherical in shape, when runoff investigation wheel and lower water temperature wheel phase
Locating piece is rotated into next stopper slot with lower water temperature wheel during to rotating.
By above-mentioned technical proposal, lower water temperature wheel and runoff investigation wheel both of which are set in the front end of double-control thermostatic valve element
Can relatively rotate between the two simultaneously.When using the constant-temperature water faucet that the valve element and handwheel are housed, water can be first rotated
Amount regulation wheel drive upper valve body is rotated, so as to realize the regulation for water flow.Because Water Temperature-Adjusting rotary knob is arranged on upper valve
In vivo, when upper valve body is rotated, thermoregulation knob and lower water temperature wheel are rotated with upper valve body together, and the water temperature of delivery port is maintained
The value set when using last time, will not change.When needing to change the water temperature of delivery port, as long as individually rotate water temperature adjusting
Section wheel, you can drive thermoregulation knob to rotate, so as to realize the regulation for output water temperature.The handwheel is so set, overall structure
It is relatively simple, while can be adjusted to water temperature and water yield respectively, leaving water temperature is not interfered with when water yield is changed, adjusting
Water yield is not interfered with while section leaving water temperature yet, is more adapted to real life and is used.The setting one of locating piece and stopper slot
The torque needed when aspect can increase lower water temperature wheel and runoff investigation wheel relatively rotates, it is to avoid in use by
Cause water temperature to change situations such as colliding with, the sound of click, click on the other hand can be sent when lower water temperature wheel is rotated
Sound, suggesting effect is played to user, and the sound for making user pass through to point out substantially knows the temperature value for increasing or reducing.
Preferably, the stopper slot side is provided with block, is provided with lower water temperature wheel lower surface and coordinates limit with block
The conflict block of lower water temperature wheel maximum rotation angle processed.
By above-mentioned technical proposal, the setting of block and conflict block can avoid the rotation process transfer in lower water temperature wheel

Preferably, the multiple for being cooperated with thermoregulation knob end surface and being driven is provided with the lower water temperature wheel
Double wedge.
Preferably, it is provided with runoff investigation wheel multiple convex with what outer surface mutual cooperation in upper valve body upper end was driven
Tooth.
Preferably, the runoff investigation wheel lateral surface is provided with the non-slipping block for being easy to rotate runoff investigation wheel.
By above-mentioned technical proposal, the setting of non-slipping block can be avoided in use due to speckling with water or bubble on hand
Foam etc. causes to rotate the inconvenience of runoff investigation wheel, it is impossible to more efficiently runoff investigation wheel is rotated, the setting of non-slipping block can
To be prevented effectively from the generation of such case.
Preferably, screw chamber upper end is provided with the cover plate for closed screw chamber.
By above-mentioned technical proposal, the presence of cover plate can be with closed screw chamber, it is to avoid water is entered into screw chamber during with water,
Cause the link screw in screw chamber that corrosion occurs.The setting of cover plate simultaneously can also be covered to screw chamber, make the handwheel
It is overall more attractive in appearance.
The beneficial effects of the invention are as follows：By to the integrally-built improvement of handwheel, when handwheel overall structure it is simpler, together
When can preferably adapt to the regulation and control needs of coaxial double-control thermostatic valve element flexible modulation is carried out to water and water temperature.
