Abstract
The utility model belongs to the improvement on the sealing ring of a pressure cooker. The utility model, which is an elastic soft ring, is characterized in that the inside of the ring is provided with sealing holes along the ring line; the inside of each of the holes is provided with a medium which expands with heat and contracts with cold; the mediums can be air or liquid; the holes can be arranged on the inner side. When the utility model is used, because the mediums are expanded for being heated, and the volume is expanded, the sealing ring clings to the upper and the lower ring lips of the pressure cooker, and the sealing effect is obvious.
Description
The utility model belongs to the improvement invention of the pot body and the seal ring between the pot cover of pressure-type pot, is specially adapted to the pressure cooker (or being pressure kettle) in the family.
Existing pressure cooker, the seal ring between pot body and the pot cover is made by elastic caoutchouc, and its section be horizontal " Y " type, utilizes self elasticity to contact with enclosing the lockjaw card up and down, and realization seals.In use, because of High Temperature High Pressure, and acid, alkali matter effect in the pot, seal ring is easy to be compressed distortion, has reduced the elasticity of material, makes it not tight with the lipped joint of the circle up and down card of pressure cooker, and seal degree reduces.
The purpose of this utility model provides a kind of seal ring that self has the bloated performance of splashing.
The purpose of this utility model is finished by following technological scheme: it is the soft circle ring of an elasticity, has the hole of sealing in this circle ring along loop wire, is filled with the medium that expands with heat and contract with cold in this hole.
The above-mentioned hole of sealing longitudinally can be circle, ellipse etc., and number can be one, two, a plurality of; Can be located at a side etc. partially; Of all kinds.
The above-mentioned medium that expands with heat and contract with cold can be for gas, liquid, and gas, liquid mix, and gas, liquid-solid body granulate mixture etc.The most cheap with the air cost, Volume Changes is also obvious.
The utility model is except that utilizing former self elasticity and circle contacts up and down, also because of being provided with vertical hole, be filled with the medium that expands with heat and contract with cold in the hole, in use, on pressure cooker, raise with temperature, medium is heated and self splashes bloatedly, stretches extended volume, makes it to connect airtight with the lockjaw of circle up and down of pressure cooker to touch, realize sealing, particularly to the pressure cooker in the family (or being pressure kettle), when pressure cooker was heated to uniform temperature, air was discharged in the pot body, pot inner pressure reduces, and temperature in the seal ring, pressure remains unchanged, and then seal ring stretches and dilates obviously, and is better to the sealing effect of pressure cooker.
If the vertical hole in the seal ring is partially in the inboard, then hole medium (air) is heated soon; Hole wall relative thin again, bloated, the distortion of easily splashing is with the lockjaw of the circle up and down card good seal of pot body.
If vertically hole is partially in the outside, then inwall is thick relatively, can more effectively keep out the acid under the temperature adjustment high pressure in pot body, the effect of alkaloid substance.
Fig. 1 is the embodiment's of technical solutions of the utility model a structural drawing
Further describe embodiment 1 below in conjunction with accompanying drawing: it is a rubber ring ring, and wherein a hole 1 is vertically run through in the inboard, is filled with air in the hole; The outside is a heavy wall 2, and the madial wall of circle ring is thinner relatively, makes stretching, extension, dilates better, and help inwardly compressing into stretching, extension up and down.Last sealing surface 3, lower sealing surface 4.
Claims (3)
1, a kind of wiper seal circle is the soft circle ring of an elasticity, it is characterized in that: have the sealing hole along loop wire in this circle ring, be filled with the medium that expands with heat and contract with cold in this hole.
2, wiper seal circle as claimed in claim 1 is characterized in that: relatively the circle ring is inboard for the above-mentioned hole of sealing longitudinally.
3, wiper seal circle as claimed in claim 1 or 2 is characterized in that: the above-mentioned medium that expands with heat and contract with cold is an air.
