In each figure, 1 is cock body, and 2 be consent, and 3 be plug valve, and 4 be valve bonnet, and 5 be scanty stomatal, and 6 be valve body, and 7 be spring, and 8 are Piston, 9 be thin air flue.

Embodiment：

Illustrate the design below in conjunction with the accompanying drawings.

As shown in figure 1, the design includes cock body 1, cock body is machined with the through hole above and below an insertion cock body at its axle center That is consent 2, consent can be difference footpath in position above and below a circular hole with footpath can also be, such as in order to install following plug valves Need this hole larger but then need to limit this aperture for heat insulating ability requirement, this just can by the aperture on top it is thicker under Portion it is thinner, i.e., consent can also be up big and down small two concentric circle holes composition, rabbet a plug valve on the top of consent 2 3, this interlocking can be realized by way of tight fit；Valve bonnet 4 of the plug valve 3 comprising a dome shape and its underface are linked to be with it The valve body 6 of one, as shown in Figure 2, Figure 3, Figure 4, the shape of such as bottomless cylindrical ampuliform of valve body 6, is this bottomless cylinder The valve body of shape ampuliform will also make beam diameter processing in its lower half, i.e. the internal diameter of the lower half of valve body 6 is slightly less than the upper half, while in valve The shoulder position of body and the surrounding periphery of valve bonnet 4 are all machined with equally distributed multiple scanty stomatals 5, and scanty stomatal does not exist preferably up and down On same vertical line but stagger, it is therefore an objective to keep away dirt, this is also that valve bonnet is designed into dome shape and scanty stomatal are not arranged in valve The reason for covering center, because center can be straight-through with following valve body valve chambers；Be in clamping connection in the bottleneck of valve body 6 one to The spring 7 that underface is stretched out, the lower end of spring is reached always at the beam diameter of valve body and scarfing device has the nahlock shape of a silica gel matter Piston 8, the diameter dimension of piston 8 is machined with one close to the internal diameter size at valve body beam diameter position at its end face center position Individual cocker catches the groove of the lower end of spring 7, it is top on its circumference wall and be all machined with the lower equally distributed eight it is approximate The thin air flue 9 of triangle taper, top thin air flue and thin air flue on the lower mutually in symmetry shape up and down and the two be spaced apart it is certain Distance up and down, as shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, circumference wall and the internal face at the beam diameter of valve body 6 of piston 8 are connecing for they Contacting surface all makees the working process of close contact, up to the effect of close contact, to be more than certain pressure in underpiston gas pressure In the case of value can above push piston 8 leave the beam diameter position of valve body 6 but be not required to completely disengage from out, i.e., be changing into by Fig. 2 shapes For such as Fig. 3 shapes, now spring 7 is by compression, though piston 8 without departing from and valve body beam diameter at inwall combination and its on the lower eight Individual thin air flue 9 begins to Down-Up to dredge the inner chamber valve chamber for discharging the enlarged diameter that a part of gases at high pressure enter valve body 6 And be outwards derived by scanty stomatal 5, when the atmospheric pressure value under piston in bottle because it is this dredge release be reduced to certain value can not be to On promote during piston that it can slowly return to original position again in the presence of the elastic force of spring 7 again, i.e., be returned to by Fig. 3 shapes such as Fig. 2 Shape, recovers closed thermal insulation function；It is some it is more special in the case of, it also occur that atmospheric pressure value is less than the feelings of the outer atmospheric pressure value of bottle in bottle Condition, the hyperbar that now plug valve 3 can be also played outside an effect for dredging balance inner and outer air pressure difference, bottle can act on piston and make It is moved down, i.e., turn to Fig. 4 shapes such as by the change of such as Fig. 2 shapes, and the contact of same piston with valve interior wall is also not required to completely disengage from out, living The top thin air flue 9 of plug can be also put the hyperbar that enter valve chamber into bottle until draught head drops in certain limit, piston 8 It can be pulled back again by spring 7 to sealed shape in situ, i.e., Fig. 2 shapes be become again by such as Fig. 4 shapes again, recover closed thermal insulation function；Spring 7 exists Can both be compressed some in whole process can also be stretched, be attached to twice up and down on piston dredge air flue 9 can be with Draught head under gentle balance release plug valve, while can also cause sliding trace stability of the piston in valve body more may be used Lean on, abundant guarantee is provided for the smooth slip of piston above-below direction., can be effective due to the decompression equilibrium function of this plug valve The inner and outer air pressure for balancing bottle stopper is poor, is effectively prevented bottle stopper by roof fall while insulation and is held, is the use of people Reduce unnecessary trouble.
