Abstract
The utility model relates to a safe and visual window for pressure cookers. The utility model is a cylindric window body which is made of transparent pressure and temperature resisting nonmetallic material and is provided with a step, and the screw thread section of the window body penetrates through a circular hole from the inner wall of a cooker lid; the exposed part of the window body is screwed on the top surface of the cooker lid by a metal nut. The transparent window body can observe food in the pressure cooker, and the upper side of a step surface of the window body is provided with a groove, wherein, the inner of which is provided with an O-shaped silicone rubber sealing ring. The window body is maintained seal with the cooker lid under nominal operating pressure, but the bottom of the groove on the window body can be broken in the state of overpressure, and the window body is not sealed with the cooker lid for enabling the pressure cooker to discharge pressure and effectively preventing the occurrence of cooker bursting accidents.
Description
The utility model relates to a kind of visual windows of pressure cooker, particularly a kind of pressure cooker secure visual window with insurance function.
The pot body of existing pressure cooker, pot cover all adopt metal material to make, thereby in the pressure cooker use, people can't observe the cooking status of pot interior food.
The utility model is intended to overcome above-mentioned shortcoming, provides a kind of people of supplying to observe the pressure cooker window of food, uses this window can play the security insurance effect again.
The utility model is achieved in that on the pot cover end face of pressure cooker, the one or more circular holes of punching out, make the cylindrical forms that have step with the nonmetallic materials of transparent withstand voltage heatproof, " O " shape silicone rubber O-ring is installed in the step surface of the forms groove of having got on the bus, groove.Microcephaly's thread segment of forms is passed above-mentioned circular hole from the pot cover inwall, appear part and be tightened on the pot cover with metal nuts.Be processed with the straight-tooth line on the cylindrical of nut, be convenient to fastening nut.
Forms both ends of the surface of the present utility model are smooth smooth, and whole clearing can be observed the food in the pressure cooker.Installed after the sealing ring in the groove on this forms step surface, under nominal operating pressure, keep sealing between forms and the pot cover, but under the superpressure state, the channel bottom of this forms will rupture, lose sealing between forms and the pot cover, make the pressure cooker pressure release, prevent the generation of fryer accident effectively.The utility model is simple in structure, and is easy to manufacture, and function is remarkable, can extensive use on the usual pressure pot.
Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.
Fig. 1 is a scheme of installation of the present utility model; Fig. 2 is along the partial sectional view of A-A among the utility model Fig. 1; Fig. 3 is the enlarged drawing of overlooking of the utility model structure; Fig. 4 is the cutaway view Amplified image of the utility model structure.Among the figure: 1, pot cover; 2, sealing ring; 3, forms; 4, nut; 5, pressure limiting valve; 6, pot body; 7, alarm valve; 8, Anti-stop cover; 9, safety valve; 10, cushion rubber.
Shown in Fig. 1-4, on a kind of pot cover (1) of pressure cooker, the centre is equipped with pressure limiting valve (5), Anti-stop cover (8) etc., the edge inwall is equipped with cushion rubber (10) etc., end face annular position is equipped with alarm valve (7), safety valve (9) and secure visual window of the present utility model, and pot cover (1) screws on pot body (6).Microcephaly's thread segment of forms of the present utility model (3) passes circular hole from the inwall of pot cover (1), with nut (4) forms (3) is tightened on the pot cover (1).Forms (3) adopt the nonmetallic materials of transparent withstand voltage heatproof to make, and its both ends of the surface are smooth smooth.The step surface of forms (3) groove of having got on the bus is equipped with sealing ring (2) in the groove.Be processed with the straight-tooth line on the cylindrical of nut (4).Secure visual window of the present utility model can be installed one, also two or more can be installed, and it not only can use on the new system pressure cooker, but also can change a social system use on old pressure cooker.
Claims (4)
1, a kind of secure visual window of pressure cooker is characterized in that: microcephaly's thread segment of forms (3), pass circular hole from the inwall of pot cover (1), and be tightened on the end face of pot cover (1) with the part that appears of nut (4) forms (3).
