The rotation of cock 2 and valve body 1 can be made to contact facial disfigurement in the high temperature fluid in valve, extruding sticks in one piece, and is difficult to
It opens, therefore, it is necessary to cooling down to valve body 1 and cock 2, starting hair in front of the door, first turn on the switch 36, battery 35 gives ring
Shape electromagnet 34 is powered, and ring electromagnet 34 generates magnetic field, and coldplate 25 is moved to the wall surface of cock 2 by magnetic field gravitation
On, extraneous cooling water passes sequentially through water inlet pipe 27, inlet opening 29, the first flexible steel in flat section tubing 32, the 26, second flexibility of cooling tube
Connecting tube 33, apopore 30, outlet pipe 28 form circulating cooling water loop so that the temperature of coldplate 25 reduces, then by cold
But plate cools down to cock 2, so that cock 2 and the rotation contact surface of valve body 1 cool down, after waiting cooling a period of time,
Turn off switch 36, ring electromagnet 34 powers off, and the magnetic field that ring electromagnet 34 generates disappears, without magnetic field gravitation, in elasticity
Under the action of the elastic potential energy of supporting rod 31, returning to original state, the disengaging of coldplate 25 is bonded with the cock 2, due to
The rotation contact surface of cock 2 and valve body 1, at this point, valve can easily be started very much by being rotated further by bull stick 5, realizes valve through supercooling
The switching function of door.In order to enable the cooling efficiency higher of cock, preferred technical solution are, the coldplate 25 is arc,
The coldplate of arc preferably can be preferably bonded with the wall surface of cock 2 so that cock can cool down faster.
In order to make cock in the case of heated deform, deformation can be adjusted, to start with valve body contact face
Valve, preferred technical solution are, as shown in figure 5, the top in the cock 2 is provided with the first cylindrical air cavity 37, it is described
Bottom of the first cylindrical air cavity 37 in the cock 2 and 1 roof contact surface of the valve body, the cock 2 is provided with the
Two cylindrical air cavitys 38, the described second cylindrical air cavity 38 is close to the cock 2 and 1 bottom wall contact surface of the valve body, the rotation
Stomata 39 is provided in plug 2,39 one end of the stomata is connected to the described first cylindrical air cavity 37,39 other end of the stomata
It is connected to the described second cylindrical air cavity 38, the air injection pipe 40 of vertical direction, the air injection pipe 40 is provided in the bull stick 5
5 upper surface of the bull stick is extended in upper end, and 40 lower end of the air injection pipe extends in the cock 2, and with first cylinder
Shape air cavity 37 is connected to, and the upper end of the air injection pipe 40 is provided with sealing cover 41, the sealing cover 41 and 40 screw thread of the air injection pipe
Connection.Air is injected into the first cylindrical air cavity 37 by air injection pipe 40, by stomata 39 so that the first cylindrical air cavity 37
It is filled with the gas with certain pressure intensity with the second cylindrical air cavity 38, sealing cover 41 is then covered and is used, work as delivery tube
What is flowed in road is high temperature fluid, and high temperature makes the contact surface of cock 2 and valve body 1 also become dilatancy and be difficult to start, this
When, it opens sealing cover 41 and first cylindrical air cavity 37 is released with the gas in the second cylindrical air cavity 38, so that
The internal diameter of cock 2 is shunk, and cock 2 keeps certain gap with valve body 1, at this moment, can easily be started valve, be realized valve
Switching function.
