Abstract
The utility model provides a fusible valve of a pressure cooker, which comprises a valve body fixed on a cooker cover; and an air stream channel for communicating the interior of the pressure cooker with the outside is formed in the valve body. The fusible valve is characterized in that the valve further comprises a fusible component; and the fusible component is arranged on the air stream channel and cuts off the communication between the interior of the pressure cooker and the external stream. When steam pressure in the pressure cooker exceeds working pressure and is still increased, the fusible component is broken down, and the steam in the cooker leaks out of the pressure cooker through the air steam channel, so that the purposes of pressure relief and safety are achieved.
Description
Technical field
The utility model relates to the meltable valve of a kind of pressure cooker.
Background technology
Existing pressure cooker generally all is equipped with a spring valve, in the pressure cooker use, when pressure still rises after pot inner pressure surpasses operating pressure maximum (88Kpa), spring in the valve body promptly is compressed, steam is outside the valve body interstitial row takes the dish out of the pot, pot inner pressure is reduced, play the security insurance effect.Practice shows that it is safe inadequately that spring valve only is set on the pressure cooker.Especially in pot, heat up overheated or when boiling dry pot,, will cause security incident if pressure can not get fast in the pot, drain timely.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of pressure cooker meltable valve, the gas channel of meltable valve will transfer open mode to from closed condition when the pressure kettle temperature is too high, thereby make pressure cooker obtain effective pressure release.
The utility model adopts following technical scheme, solve the problems of the technologies described above: the meltable valve of a kind of pressure cooker, comprise the valve body that is fixed on the pot cover, be provided with the gas channel that pressure cooker inside is in communication with the outside in the valve body, it is characterized in that: also comprise a meltable assembly, this meltable assembly is arranged on the gas channel, and the cut-out pressure pot inner with being communicated with of extraneous air-flow.
Further, described meltable assembly is a fuse sheet, and is arranged on the end of gas channel, and by screw in compression on valve body; Wherein be provided with the through hole that docks with gas channel in the screw.
Be provided with leak-proof gasket between the valve body of the meltable valve of above-mentioned pressure cooker and the pot cover.
The meltable valve of above-mentioned pressure cooker also comprises a clamp nut, and this clamp nut is fastened on valve body on the pot cover.
The utility model is provided with fuse sheet on the gas channel of valve body, too high or boil dry pot and when causing the pressure cooker internal temperature too high when pot inner pressure, the interior high-temperature vapour of pot will enter gas channel and fuse sheet will be punctured, and drain to extraneous, thereby reach the safety relief effect.After fuse sheet is breakdown, screw is backed out, taken out the fuse sheet that damages, change new fuse sheet again and get final product with screwdriver.The utility model has improved the security of pressure cooker, and easy for installation, is convenient to safeguard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises valve body 3, meltable assembly 2, packing ring 4, clamp nut 5, wherein is provided with gas channel 31 in the valve body 3, and clamp nut 5 is provided with pore 51.Valve body 3 is fastened on the pot cover 6 by clamp nut 5, and leak-proof gasket 4 is arranged between valve body 3 and the pot cover 6.Pore 51 on the clamp nut 5 is communicated with gas channel 31, and then pressure cooker inside is in communication with the outside by gas channel 31.In the present embodiment, meltable assembly 2 is provided with the through hole 11 that docks with gas channel 31 for be fixed on the fuse sheet of gas channel 31 tops by screw 1 in the screw 1.Under the normal condition, fuse sheet 2 has cut off being communicated with of gas channel and the pressure cooker external world, thus pressure cooker inner with the external world be disconnected; When the intensification of boosting in the pressure cooker was too high, fuse sheet 2 was breakdown, and pressure cooker inside is in communication with the outside by gas channel 31.
When pressure cooker of the present utility model was equipped with in use, when the pressure in the pressure cooker surpassed maximum working pressure (MWP) and acquires a certain degree, high-temperature vapour entered in the gas channel 31 by the pore on the clamp nut 5 51 and acts on the fuse sheet 2, and punctures fuse sheet 2; The final high temperature steam is discharged outside the pot by the through hole in the screw 1 11, realizes the complete pressure release of pressure cooker, guarantees safety.
After fuse sheet was breakdown because of superpressure, during the fuse sheet that renews, an available word bottle opener was back-outed bleed screw 1, and the fuse sheet that punctures is taken out, and changed the new fuse sheet of a slice, and the bleed screw 1 of screwing on then gets final product.
Claims (4)
1. meltable valve of pressure cooker, comprise the valve body that is fixed on the pot cover, be provided with the gas channel that pressure cooker inside is in communication with the outside in the valve body, it is characterized in that: also comprise a meltable assembly, this meltable assembly is arranged on the gas channel, and the cut-out pressure pot inner with being communicated with of extraneous beam.
2. the meltable valve of pressure cooker according to claim 1 is characterized in that: described meltable assembly is a fuse sheet, and is arranged on the end of gas channel, and by screw in compression on valve body; Wherein be provided with the through hole that docks with gas channel in the screw.
