It is fixed, it can push sealing sliding block that flow pipe is intercepted sealing after extensible member volume expansion, after extensible member volume contraction
Sealing sliding block can be pushed to discharge flow pipe to open；It can be produced after being equipped with the energization contacted with extensible member in or beyond the extensible member
The heating wire of heat amount, heating wire are connected with heating wires.
As an improvement, being equipped in the valve casing of the contraction chamber using signal collecting element made of piezoelectric material, Ji Yuxin
The signal acquisition line of number acquisition elements connection；Spring is additionally provided in the contraction chamber, one end of spring and signal collecting element connect
It connects, the other end of spring is connect with sealing sliding block.
It improves again, the valve casing is equipped with the entrance and exit being connected to flow pipe, the sealing sliding block activity setting
In flow pipe, and the flow pipe between entrance and outlet can be intercepted sealing under extensible member effect or incited somebody to action by sealing sliding block
Flow pipe between entrance and outlet, which discharges, to be opened.
It improves again, the line segments opposite with exporting are tapered in the flow pipe, also are provided with energy on the sealing sliding block
The tapered end cooperated with the line segments of taper.
It improves again, the invention also includes the power switches of power supply and control power supply on-off with heating wires.
It improves again, the invention also includes the indicator lights connecting with signal acquisition line.
Compared with the prior art, the advantages of the present invention are as follows: mobile by setting sealing sliding block and driving sealing sliding block
Using extensible member made of negative temperature expanding material, by heated, the cooling movement for realizing sealing sliding block of extensible member, thus will
Flow pipe release opens or flow pipe is intercepted sealing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (opening state) of on-off valve in the embodiment of the present invention.
Fig. 2 is the structural schematic diagram (sealing state) of on-off valve in the embodiment of the present invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
On-off valve as shown in Figure 1, 2, including the interior valve casing 1 equipped with flow pipe 11, the valve casing 1 is equipped with and circulation
The entrance 12 and outlet 13 that pipeline 11 is connected to, the sealing sliding block 2 is movably arranged on 11 in flow pipe, is set in the valve casing 1
There is the sealing sliding block 2 for being formed with contraction chamber 14 between valve casing, is equipped in the contraction chamber 12 and uses negative temperature expanding material system
At extensible member 3, one end of extensible member 3 and sealing sliding block 2 are fixed, and the other end and valve casing 1 are fixed, are equipped in or beyond extensible member 3
The heating wire 7 of heat can be generated after the energization contacted with extensible member, heating wire 7 is connected with heating wires 8, and heating wires are also connected with
There is power supply 9 and controls the power switch 10 of power supply on-off；It can push sealing sliding block 2 that will enter after extensible member volume expansion
Flow pipe between mouth and outlet intercepts sealing, can push sealing sliding block will be between entrance and outlet after extensible member volume contraction
Flow pipe discharge open.
In the present embodiment, the line segments opposite with outlet 13 are tapered in flow pipe, also are provided on the sealing sliding block 2
The tapered end that can cooperate with the line segments of taper.
It is equipped in the valve casing of the contraction chamber 14 using signal collecting element 4 made of piezoelectric material, and and signal acquisition
The signal acquisition line 5 of element connection；Spring 6 is additionally provided in the contraction chamber, one end of spring 6 and signal collecting element 5 connect
It connects, the other end of spring 6 is connect with sealing sliding block 2；Signal acquisition line 5 is connected with indicator light 15.
When above-mentioned on-off valve needs to open, 10 are turned off the power switch, power supply 9 is made to supply electricity to heating wire 7, heating wire 7
Work on power, heating wire according to joule principle generate thermal energy, thermal energy formula be Q=UIT (U is input power, and I is input current,
T is conduction time), the thermal energy of heating wire can be such that 3 internal temperature of extensible member increases, and extensible member 3 uses negative temperature expanding material, body
Product is gradually tapered up along cavity wall is shunk, to pull sealing sliding block 2 to move to shrinkage direction, to make between entrance and exit
Channel open, until being pulled to limit point stops movement, valve inner pipeline degree of opening reaches maximum, and valve flux is by 0 to maximum
Throughput process is because there are an amount of delay for the material property of extensible member, therefore the process that can achieve unlatching is gently stablized.Work as electricity
After source switch 10 is opened, heating wire power supply is disconnected, and after heating wire stops power supply, heating wire temperature is reduced, and is affected by temperature, and is stretched
The volume of part 3 starts to be gradually expanded, and sealing sliding block is pushed to move closer to the outlet of flow pipe, after being lower than 40 degree, extensible member 3
A temperature expansion material of paying restore to maximum volume, finally be bonded with outlet, entrance is truncated and exports between access.Power-off is dynamic
Make and be closed completely there are a delay time, delay time to when work electric current and voltage value it is related, operating current and electricity
Pressing is fixed, so delay time is a fixed value, thus achievees the effect that time-delay closing.
The indicating mechanism being made of in valve casing 1 spring and piezoelectric material, valve opening process seal sliding block in moving process
In, it drives spring to generate deformation quantity and squeezes signal collecting element made of piezoelectric material, so that output voltage signal, seals sliding block
Moving process voltage signal constantly change, when seal sliding block slide to the flux aperture maximum of spacing place, i.e. on-off valve when, voltage
Signal reaches stationary value, and maximum and constant, then indication valve has fully opened；After closing valve, sealing sliding block be gradually closed into
Pipeline between mouth and outlet, spring stretch, and signal collecting element made of piezoelectric material is gradually reduced by spring pressure, electricity
Signal is pressed to reduce, until sealing sliding block is fully sealed, the voltage value of signal collecting element is reduced to minimum, and remains motionless,
It then indicates to be closed completely in on-off valve.
