Chamber is connected by the first port with branch chamber, and hot-water cavity is connected by the second port with branch chamber, is provided with and first in back cavity
The piston cylinder of hollow setting is provided with the check valve of port connection, branch chamber, between the outer wall of piston cylinder and the inwall of outer sleeve
There is certain interval, the outer wall of piston cylinder is provided with annular groove, the barrel of outer sleeve and offers water inlet, connects with hot-water cavity
Offered on logical hot water outlet and the backwater outlet connected with back cavity, the barrel of piston cylinder and connected with water inlet and be located at
First through hole, the second through hole connected with hot-water cavity and the third through-hole connected with back cavity at annular groove；Piston cylinder
Temperature-sensitive actuator and the first elastic component are inside provided with, temperature-sensitive actuator is provided with seal disc, and the first elastic component acts on temperature-sensitive rush
Dynamic device make it that the left end of temperature-sensitive actuator passes through the second through hole and seal disc to be closed and be provided with bullet on the second through hole, outer sleeve inwall
Property component, elastic parts act on the left end of temperature-sensitive actuator so that piston cylinder close the first port.
In the present invention, by the setting of piston cylinder annular groove branch chamber can be further divided into three it is relatively independent
Chamber, be respectively the first chamber for directly connect with hot-water cavity, the second chamber directly connected with piston tube inner chamber and directly with time
Flow the 3rd chamber of chamber connection.It is arranged such, can stops that the current flowed into from water inlet are largely lost in from the both sides of the second chamber
In one chamber or the 3rd chamber, and current energy can be easy to a large amount of and rapidly entered in the second chamber by first through hole in piston cylinder
In chamber, so as to accelerate the temperature-sensitive gearing of temperature-sensitive actuator.When the present invention is applied, the hot water of water inlet and hot water supply system
Outlet conduit is connected, and backwater outlet can be connected with the cold water inlet road of hot water supply system also to be connected with storage tank, and hot
Water out is then connected with hot water tap.When leak caused by hot water tap causes nature leak or thought because of aging, although heat
Retaining cold water and can flow out hot water tap in water cavity and the first chamber, but set by the gap between piston cylinder and outer sleeve, it can make
Current are rapid under the drive of pressure differential to be flowed into the first chamber from water inlet and is put down with maintaining pressure new in this structure in hot-water cavity
Weighing apparatus, so as to avoid piston cylinder from occurring to judge by accident and accidental activation shunting work in which case.
When zero-bit state of the present invention namely non-working condition, what is retained in each pipeline and outer sleeve is normal temperature cold water, thus
Temperature-sensitive actuator is in original shrinkage state.Now, under supporting role of the elastic parts to temperature-sensitive actuator left end, piston
Cylinder right-hand member closes the first port；Under supporting role of first elastic component to temperature-sensitive actuator right-hand member, seal disc then closes second
Through hole.Because branch chamber is not connected with hot-water cavity and back cavity, thus under such a state, hot water outlet and backwater exit
It will not there are flowing out.When opening hot water tap, the cold water that retains in hot-water cavity and the first chamber then flows out rapidly, by
This causes pressure differential so that piston cylinder is promptly moved to the left.Under the resigning effect of elastic parts, the left end of piston cylinder is then rapid
The second port is closed, while its right-hand member then opens rapidly the first port.Because branch chamber is connected with back cavity, itself and hot water
Chamber is isolated, therefore the cold water that retains flowed into from water inlet in the second chamber will not then flow out at hot water tap, but from first
Through hole is flowed into the inner chamber of piston cylinder, then flows into the 3rd chamber by third through-hole, then flows into back cavity by the first port.Due to
First passage port is provided with check valve, thus the current for flowing into back cavity through the first port will not flow backwards, but directly
Connect through in backwater outlet return to cold water inlet road or flowing directly into storage tank.When the current flowed into from water inlet are warp
Hot water supply system heating after hot water when, then because experiencing the change of water temperature heat expansion deformation progressively occurs for temperature-sensitive actuator,
Plus the supporting role of elastic parts, this heat expansion deformation enables seal disc to overcome the supporting role of the first elastic component to move right
And the second through hole is opened, while under the induced effect of the first elastic component, piston cylinder can also close the first port rapidly.Now,
Because branch chamber is connected with hot-water cavity, it is isolated with back cavity, therefore flows into the hot water of the second chamber then from from water inlet
One through hole is flowed into piston tube inner chamber, then flows into the first chamber by the second through hole, then flows into hot-water cavity by the second port, finally
Hot water tap is flowed out through hot water outlet.
To realize that check valve prevents the effect of current refluence, further, the check valve includes what left and right end was open
Valve body, the left end opening of valve body is connected with first port, its right-end openings and the backwater outlet, is set in valve body
There is left end to close the end socket and the 3rd elastic component of right-end openings, the width of end socket blind end is more than the width of valve body left end opening,
The side wall of end socket is provided with multiple fourth holes connected with end socket openend, and the 3rd elastic component acts on the openend of end socket,
So that the left end opening of end socket closed valve.The present invention work when, water flow through valve body left end opening enter valve body in, due to by
Pressure to current is acted on, and end socket can then overcome the supporting role of the 3rd elastic component and move right, so then can be from this left end
The right-hand member of end socket, then the outlet of the outflow backwater of the right-end openings through valve body are flowed into and flowed into through fourth hole at opening.If crossing herein
Cheng Zhong, current flow backwards, then active force that can be to end socket one to the left makes the left end opening of its closed valve, so can then prevent
The left end opening that water flows through valve body is flow backwards into the 3rd chamber.
To realize the temperature-sensitive gearing of temperature-sensitive actuator, further, the temperature-sensitive actuator is set successively from right to left
It is equipped with outside temperature-sensitive portion, the deformations being connected with temperature-sensitive portion and the push rod being connected with deformations, push rod to be arranged with and may pass through described
The housing being connected respectively with temperature-sensitive portion and guide cylinder is arranged with outside the guide cylinder of two through holes, deformations, housing is externally provided with annular even
Fitting, second elastic component is sheathed on temperature-sensitive actuator and its two ends is respectively acting on circular connector and the piston cylinder
Inwall.In the present invention, when in piston tube inner chamber being normal temperature cold water, deformations are then zero-bit state, and now push rod is relative leads
Contraction state is in cylinder；And when in piston tube inner chamber being hot water, deformations are then issued in the temperature-sensitive gearing in temperature-sensitive portion
Heat bulging becomes, and now make it that push rod is oppositely oriented the elongation movement of cylinder generation to the left.Using when, due to the resigning of elastic parts
Distance is certain, thus when relative move to left occurs for push rod, guide cylinder, housing and temperature-sensitive portion then occur to move to right relatively, so that
Obtain seal disc and open the second through hole, while under the induced effect of the first elastic component, piston cylinder also moves to right the first port of closing.

The left end in temperature-sensitive actuator is touched, and piston cylinder is closed the first port；And when open hot-water switch when, temperature-sensitive actuator also with
Piston cylinder and move to left rapidly so that gland overcomes the pressure of the second elastic component and is pressed in the right-hand member of temperature adjustment bar rapidly, so that real
Existing closing and unlatching to first port of the piston cylinder to the second port；And when the current flowed into from water inlet are hot water,
The push rod stretching that temperature-sensitive actuator then occurs heat expansion deformation and makes to be arranged in temperature-sensitive actuator continues to withstand gland.Due to now
Second elastic component is in maximum elastic deformation position, for the heat expansion deformation of resigning temperature-sensitive actuator, and the first elastic component will be by
Step is compressed so that seal disc opens the second through hole.Thus, understand between temperature-sensitive actuator left end and temperature adjustment bar right-hand member it is original away from
From determine open the second through hole needed for the water temperature number of degrees.If this is distant, higher water temperature namely temperature-sensitive actuator are needed
Need to occur larger deformation could open the second through hole the first port of closing；If this is closer to the distance, relatively low water temperature namely sense
Less deformation, which occurs, for warm actuator also can open the second through hole and flow out hot water.Thus, by adjusting temperature adjustment bar opposing left
