Abstract
The utility model provides an explosion-proof device for a pressure cooker, which is disclosed in the specification. The utility model is characterized in that a safety cover 2 is arranged on a cooker cover 6; pressure in the cooker is arranged within the safety factor through a spring 4 and a nut 5; a sealing pad 3 is arranged between the safety cover 2 and the cooker cover 6. The utility model has the advantages that the utility model achieves an explosion-proof purpose with simple structure; the manufacture is easy; the cost is low.
Description
The utility model belongs to explosion-protection equipment, specifically, is a kind of explosion-protection equipment that is used on the pressure cooker.
The design feature of pressure cooker safety device is that the pressure release pore is less at present, stop up easily, and be except that original pressure limiting valve, to increase by a covering device on the pot cover again, some repetition seems, production cost is risen, little because of the aperture, clean and observe inconvenience, dredge if the user has to neglect slightly, just occur explosion accident easily.
The purpose of this utility model provides a kind of anti-exploding unit of pressure cooker, to ensure the safety of user's person and property reliably.
The purpose of this utility model realizes by following measure, around in pressure cooker cover 6 central authorities the hole of pressure limiting valves being installed, beat several holes 7, the structure of pressure limiting valve is changed make protecting cap 2 and be pressed on the hole 7, between pot cover 6 and the protecting cap 2 sealing gasket 3 is arranged, pot cover 6 inwalls are equipped with spring 4 and nut 5.The size of adjusting spring forces with nut 5 makes the sealing load respective change of protecting cap 2, has also just set the safe pressure scope of pressure cooker simultaneously.
The utility model has been made the simple structure change to the pressure limiting valve of existing pressure cooker cover central authorities, keep original function, increased explosion-protection equipment, it is manufactured easily, cost is low, and dependable performance is convenient to scrub and observe, use relievedly, and need not increase the safety that other device can ensure the pressure cooker user person and property effectively again.
Narrate below in conjunction with drawings and Examples
Fig. 1 is a structural representation of the present utility model
With reference to accompanying drawing is enforcement figure of the present utility model, and the protecting cap 2 of this anti-exploding unit of pressure cooker utilizes spring 4, nut 5 and sealing gasket 3 to be pressed on the hole 7 of pot cover 6, with its sealing with suitable pressure.Under the normal operating position, keeping the pressure in the pot with pressure limiting valve 1 is design work pressure.After aperture 8 takes place to stop up that pressure limiting valve is 1 malfunctioning, pot inner pressure surpasses operating pressure, protecting cap 2 rises and opens, discharge in the gap that the pot inner fluid is opened between the hole on the pot cover 67 and protecting cap 2 and pot cover 6, pot inner pressure is descended, thereby guaranteed the safety of pressure cooker, because the hole 7 on the pot cover 6 is bigger than the safety vent of existing pressure cooker, and quantity is again nearly more than 5, be equivalent to the safety valve more than 5 covers is being installed on the pressure cooker, make it be almost 0 because of taking place to stop up the probability that danger occurs.And the aperture scope of protecting cap 2 is also bigger, can design as required in 3-10 millimeter even bigger again size range, opens at protecting cap 2, after pot inner pressure reduces, resets under the deadweight effect of the elastic force of spring 4 and whole explosion-protection equipment ...So just guaranteed the safe in utilization of pressure cooker.
Claims (3)
1, a kind of anti-exploding unit of pressure cooker, protecting cap 2 is installed on the pot cover 6, it is characterized in that protecting cap 2 seals the hole on the pot cover 67 under spring 4 effects, between protecting cap 2 and the pot cover 6 seal 3 is arranged, inner face at pot cover 6 is equipped with spring 4 and nut 5, and the size by setting spring power guarantees that the pressure of pressure cooker in using is within safety coefficient.
2, anti-exploding unit of pressure cooker according to claim 1 is characterized in that protecting cap 2 central limited valves 1.
3, anti-exploding unit of pressure cooker according to claim 1 and 2, the diameter that it is characterized in that the hole 7 on the pot cover 6 is the 3-10 millimeter, quantity is 5-10.
