Abstract
The utility model relates to an improvement for a safety valve of a household pressure cooker, which is composed of a valve cap, a valve seat, a seal gasket pushed on a valve seat, a valve core and a spring sheathed on the valve core, wherein the valve cap is provided with an air leakage hole and a valve core extending hole, and the spring is respectively pushed between the valve core and the valve cap. The sealing gasket and the valve core can be automatically jacked by gas pressure for decompression when the gas of the pressure cooker exceeds nominal pressure. The utility model has the advantages of compact structure, safe and convenient usage, etc. The utility model is suitable for pressure cookers with different specifications and shapes to use.
Description
The utility model relates to a kind of improvement of the safety valve on the accessory of family expenses pressure cooker, particularly pressure cooker.
Existing pressure cooker is safe in utilization in order to guarantee it, usually all on pressure cooker lid, load onto fuse sheet or safety valve, when the pressure in the pot body surpassed specified air pressure (200KPa), fuse sheet or safety valve can discharge gas in the pot automatically, thereby guarantee the safety that pressure cooker uses.But the former was owing to used for a long time, and the fuse sheet hardening tends to malfunctioningly, does not have the safety guarantee effect; Latter's unreasonable structure is used inconvenience, the cost height.
It is a kind of safe in utilization, convenient that the purpose of the utility model is to provide, pressure cooker safety valve rational in infrastructure.
The pressure cooker safety valve is contained in the valve seat of bonnet bottom by the bonnet that is fixed on nut on the pot cover, roof pressure on the valve seat port seal washer, spool and the spring that is enclosed within on the spool form.Have bleeder port on the sidewall of bonnet, the top has one and stretches out the hole for what spool passed; Boss is arranged on the spool, and the two ends of spring withstand on respectively on the roof of the boss of spool and bonnet.
Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The pressure cooker safety valve comprises with nut 13 and is fixed on bonnet 6 on the pot cover 14, is threaded in the valve seat 11 of bonnet 6 bottoms, with seal washer 9 and the spool 3 of spring 5 roof pressures on valve seat 11 ports.
Have the bleeder port 7 of 2 symmetries on bonnet (6) sidewall, have a hole of stretching out that supplies spool 3 to slide and pass on the roof, spool 3 is shaped on circle rank shape boss 8 at valve seat 11 port position places, the two ends of spring 5 withstand on respectively on boss 8 and bonnet 6 roofs, boss 8 is " bowl " shape with valve seat 11 opposite faces, seal washer 9 matches with it, and envelope is pressed on valve seat 11 ports.
O-ring seals 10,12 is housed between valve cylinder 6 and pot cover 14, the valve seat 11.The spool 3 usefulness pins of stretching outside bonnet 64 are connected with valve handle 2 hinges, and valve handle 2 is equipped with shifting block 1.
When the utility model is assemblied in when using on the pressure cooker.If the pot internal gas pressure rises to specified air pressure (200KPa), the pot internal gas pressure will move seal washer 9 and boss 8 jack-up on the spool 3, at this moment, valve seat 11 communicates with bonnet 6, pot body, and overvoltage gas is discharged rapidly by the bleeder port 7 on the bonnet 6, thereby has guaranteed the safety that pressure cooker uses; When the end after the pot internal gas pressure discharging during in the active force of spring 5, the boss 8 of spool 3 and sealing ring 9 roof pressure again seal up valve seat 11.If the pot internal gas pressure does not surpass specified air pressure, need again gas in the pot is discharged, only need stir shifting block 1, spool 3 will drive on the seal washer 9 and move, and can reach the purpose of emission gases equally.
Obviously, the utlity model has structure compactness, system easy to use, safe The number advantages of higher are suitable for being assemblied on the family expenses pressure cooker of various shapes, specification and make With.
