One mode of execution is that the moving piece and a pressure cooker cover are sealed in a movable, the fixing piece is fixed with the moving piece, one end of the compression spring is abutted against the fixing piece, and the other end is pushed against the pressure cooker cover; the other mode of execution is that the moving piece and the fixing piece are sealed in a movable way, the fixing piece is fixed with the pressure cooker cover, one end of the compression spring is abutted against the moving piece, and the other end is pushed against the inside of the fixing piece. The utility model can ensure the safety performance of the opening and the closure of the pressure cooker cover as well as can carry out the pressure relief to enable the original open stopping valve has the function of a safety valve.
Description
Technical field
The utility model relates to the pressure cooker manufacturing technology, and what especially relate to a kind of pressure cooker only drives safety device.
Background technology
Existing pressure cooker generally is provided with pressure limiting valve, stopping valve, safety valve respectively, and the stopping valve major function is opened pot cover when preventing from the pot pressure to be arranged and met accident.Stopping valve by valve rod, valve seat, only open tongue piece, only open part, spring is formed, valve rod is suspended on the valve seat; Only opening the upper end of part and only open tongue piece and link to each other, matches with guide groove on the lower handle in the bottom, and spring is located between the middle part and upper handle of only opening part.When pot body and pot cover fasten when not in place, only open part and under the effect of spring, make and only open the rising that tongue piece blocks valve rod, as pressure is arranged in the pot, can guarantee that pot inner pressure is in safe range by the gap pressure release of valve seat and valve rod.When pot body and pot cover fasten when putting in place, only opening part cooperates the compression spring to make and only open the lifting position that tongue piece is abdicated valve rod with lower handle, valve rod can freely rise, as pressure is arranged in the pot, promoting valve rod rises in the hole of upper handle setting, stoped the reciprocating motion of only opening tongue piece, only open part and lower handle card jail, pot cover is not opened, guaranteed the security performance of uncapping, had only in pot inner pressure drops to the safe pressure scope, valve rod since the gravity effect fall, only opening tongue piece has reciprocating space, could the smooth opening pot cover.This stopping valve function of use is single, can not play the safeguard protection effect of release when the pressure cooker pot inner pressure is excessive, needs to be used the safeguard protection requirement that just can reach pressure cooker with safety valve.
Safety valve mainly plays the safeguard protection effect of release when the pressure cooker pot inner pressure is excessive, is made up of spool, nut, valve seat, spring, sealing ring, and spool and valve seat top are provided with pressure release passage, are provided with spring in spool and the valve seat.When pot inner pressure in the safe pressure scope, spool and valve seat are under the effect of spring, pressure release passage is sealed; When pot inner pressure during greater than safety value, spring is compressed, and moves on the relative valve seat of spool, and pressure release passage is connected, and carries out pressure release, guarantees the safe in utilization of pressure cooker.
Stopping valve and safety valve are set on the pot cover simultaneously, and the many and structure of perforate repeats to be provided with.Utility model patent ZL99237321.2 discloses a kind of part-structure of pressure cooker stopping valve bar, comprise pressure cooker cover, be equipped with on the through hole of pressure cooker lid one lateral margin recess can upper and lower slip the stopping valve bar, stopping valve bar middle part offers runs through through hole, and this runs through and is provided with meltable partition in the through hole following side.Produce HTHP in the pressure cooker pot, and the safety valve on the pressure cooker is for some reason can't release the time, the gases at high pressure in the pot just break through meltable partition and go out a pot body through running through through hole, thereby reach the safeguard protection effect.
Patent ZL01222175.9 discloses a kind of pressure cooker safety locking motion, comprise pressure limiting valve, safety valve, stopping valve, combination push piece, upper handle is provided with and can holds the perforate that stopping valve moves, and safety valve is located in the stopping valve, and safety valve integral body becomes the spool of stopping valve.Because safety valve is located in the stopping valve, stopping valve weight is bigger, is difficult to satisfy simultaneously the quantification requirement of folding lid safe pressure in GB15066-94 or the GB13623-92 pressure cooker national standard.
Summary of the invention
But the utility model provides a kind of pressure cooker of release only to drive safety device, both can guarantee the security performance of pressure cooker open and close cover, again can pressure release when pot inner pressure transships, and make original stopping valve have the function of safety valve concurrently.
But a kind of pressure cooker of release is only driven safety device, comprises stopping valve, and the valve seat of stopping valve is become by fixture, moving member and compression spring set, and the valve rod of stopping valve is suspended on the moving member.
Described moving member and pressure cooker lid movable sealing, fixture and moving member are fixed, and compression spring one end is against on the fixture, and the other end withstands on the pot cover of pressure cooker.
Described moving member and fixture movable sealing, fixture and pressure cooker lid are fixed, and compression spring one end is against on the moving member, and the other end withstands on the inboard of fixture.
The utility model device and handle portion are used, and keep original function of only opening, when pot inner pressure during greater than safety value, the promotion moving member overcomes the compression spring and produces mobile, the movable sealing emaciated face is opened, pot inside and outside is linked up lost heart, guarantee the pressure cooker safety relief.On pot cover, can save safety valve, increase the intensity of pot cover, also make the contour structures of pot cover arrange freedom, brief more, reduce the production cost of pressure cooker simultaneously.
Description of drawings

Fig. 2 is a kind of valve seat, valve rod, pot cover fit structure schematic diagram of embodiment;
Fig. 3 is valve seat, valve rod, the pot cover fit structure schematic diagram of another kind of embodiment.
The specific embodiment
As figure, the stopping valve of pressure cooker by valve rod 4, valve seat 5, only open tongue piece 6, only open part 7, spring 8 is formed, valve rod 4 is suspended on the valve seat 5; Only opening the upper end of part 7 and only open tongue piece 6 and link to each other, matches with guide groove 10 on the lower handle 9 in the bottom, and spring 8 is located at 2 of the middle part of only opening part 7 and upper handles.When pot body 11 and pot cover 1 fasten when not in place, only open part 7 and under the effect of spring 8, make and only open the rising that tongue piece 6 blocks valve rod 4, as pressure is arranged in the pot, can guarantee that pot inner pressure is in safe range by the gap pressure release of valve seat 5 with valve rod 4.When pot body 11 puts in place with pot cover 1 fastening, only opening part 7 cooperates compression spring 8 to make and only open the lifting position that tongue piece 6 is abdicated valve rod 4 with lower handle 9, valve rod 4 has ascending motion space freely, as pressure is arranged in the pot, promoting valve rod 4 rises in the hole 3 of upper handle 2 settings, stoped the reciprocating motion of only opening tongue piece 6, only open part 7 and lower handle 9 card jails, pot cover is not opened, guaranteed the security performance of uncapping, had only in pot inner pressure drops to the safe pressure scope, valve rod 4 since the gravity effect fall, only opening tongue piece 6 has reciprocating space, could the smooth opening pot cover.
