Description
The utility model is a kind of safety anti-explosive device of pressure cooker, belongs to civilian pressure cooker accessory manufacturing field in addition.
The pressure cooker cooking food, because fast ripe easy shortcake, therefore extremely the consumer welcomes, and uses more and more general.Yet the pressure cooker explosion accident but frequently takes place, and the consumer is struck fear into to the use of pressure cooker.Since pressure cooker came out, people did not stop all the time to the research that how to prevent the pressure cooker blast.Invented Anti-stop cover in order to prevent the pressure cooker blast pipe from stopping up; Invented safety valve, alarm valve and explosion proof window (hole) etc. for controlled pressure pot pressure superelevation,, fundamentally do not stopped the pressure cooker explosion accident though these inventions play a role to preventing the pressure cooker blast.Because, be installed in the Anti-stop cover of blast pipe bottom, sometimes also can be blocked, resembling large-area animal skin etc. can live the filter opening sealing label on the Anti-stop cover.Safety valve, alarm valve, the steam vent of their bottoms is very little, is blocked up by food in the pot easilier.What deserves to be mentioned is, a kind of safety valve that fuse sheet is installed, it is except easy blocked, the fuse sheet area is little, and the force value instability that steam breaks through also is fatal weakness, and fuse sheet is replaced with other similar disk by the consumer easily, loses its security function.The principle of explosion proof window (hole) is to be out of shape when utilizing the sealing ring superpressure, make sealing ring lose sealing by window (hole) mouth of setting, realizing the purpose of pressure-relief explosion-proof, because the hardness number of sealing ring changes with the length of service time, thereby the pressure release value of explosion proof window (hole) can't be determined.So, on pressure cooker, go back the desirable explosion-protection equipment of neither one at present.
The purpose of this utility model is exactly at above existing problems, and a kind of permanently effective pressure cooker explosion-proof apparatus is provided, and uses this explosion-proof apparatus, and the security performance of pressure cooker is more reliable.
Pressure cooker explosion-proof apparatus of the present utility model mainly comprises device body (1), dust-separation nut (2), drips and mould adhesive sticker sealing label (3), hold-down nut (4), device body sealing ring (5), anti-blocking nut (7), explosion disk (8), explosion disk sealing ring (9).Wherein device body sealing ring (5) is installed in the escape of last thread segment of device body (1), and the last thread segment of device body (1) passes behind its installing hole fastening with hold-down nut (4) from pot cover (6) inwall.Dust-separation nut (2) is screwed on the last thread segment of device body (1), and is tight with pot cover (6) spinning.Drip and to mould adhesive sticker sealing label (3) and be bonded on the recessed plane, dust-separation nut (2) top.Explosion disk sealing ring (9) is installed in the annular groove of following thread segment screw terminal of device body (1), device body (1) bottom end face is provided with several grooves (1-1), explosion disk (8) bottom interior wall is provided with leading of some forms and splits groove (8-2), earlier the inner chamber of into anti-blocking nut (7) will be prevented beneathly on explosion disk (8) mouth, and then anti-blocking nut (7) is tightened on the following thread segment of device body (1), the centre bore of device body (1) is up-small and down-big, be inverted tubaeform, anti-blocking nut (7) is provided with several surface grooves (7-1), inner hole groove (7-2) and cylindrical groove (7-3) interpenetrate between the groove.
Adopt the advantage of pressure cooker explosion-proof apparatus of the present utility model to be:
1, the groove (1-1) on device body (1) bottom end face, general disk is installed into can be produced leakage, can't replace explosion disk (8) to use, have only the explosion disk of the present utility model of use (8) could keep sealing, prevent that the consumer from mismatching and lead to the pressure cooker explosion accident.
2, explosion disk (8) adopts device body (1) external screw thread fixed form, be different from the fixed form of fuse sheet with the screw thread plunger, it can make steam vent air inlet area increase, and has equally also increased the compression area of explosion disk (8), can guarantee that steam breaks through the stability of force value, also helps anti-blocking.
3, leading of explosion disk (8) inwall bottom split groove (8-2), can guarantee that explosion disk (8) successfully tears the material layer pressure release under the pressure of setting, improved the explosion-proof reliability of pressure cooker.
4, the surface groove (7-1) on the anti-blocking nut (7), inner hole groove (7-2) and cylindrical groove (7-3) are different from the plane filter opening on the existing Anti-stop cover, communicate with each other between them, have the multi-azimuth tridimensional choke preventing function.
5, dust-separation nut (2) can make the explosion-proof apparatus steam vent not corroded by outer foreign matter filling of pot and poor environment, guarantees long-term use.
The utility model is simple in structure, and is easy to manufacture, and explosion-proof effect is splendid.It is consistent with original safety valve or alarm valve that the size of installation position of the present utility model keeps, and both can use on the pressure cooker of new system, can use on original pressure cooker again, and configuration or replacing are convenient.
