Abstract
The utility model relates to a high pressure cooker pressure-limited valve with a security cover. The utility model is to provide a high pressure cooker pressure-limited valve with a security cover which is simple in structure, convenient in disassembly and washing, secure in use and low in cost. The technical scheme to solve the problem is that: the utility model is provided with a pressure-limited valve and a handle on the pressure-limited valve. The screw is arranged between the valve and the handle for connection. The structural characteristics are that: a security cover whose section is basically in 'n' shape is arranged between the pressure-limited valve and the handle. A hole is arranged in the center of the security cover. The utility model is mainly used for high pressure pan.
Description
Technical field
The utility model relates to a kind of pressure cooker pressure limiting valve that has safety guard.Be mainly used in pressure cooker.
Background technology
At present, existing pressure cooker pressure limiting valve is an iron pouring weight that is enclosed within on the pot cover venthole, also has venthole on the pressure limiting valve, when the air pressure in the pressure cooker reaches the setting limit, and directly ejection the hole of steam from pressure limiting valve.People generally have a kind of like this experience, when the gas in the pressure cooker is accompanied by the noise ejection, stands in the bystander and have a kind of probably cloth sense, and the hot gas of sensation ejection can have injury to health, therefore feels dangerous.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in structure, safe in utilization, unpick and wash conveniently, the pressure cooker pressure limiting valve that has safety guard with low cost.
The technical scheme that the utility model adopted is: the pressure cooker pressure limiting valve that has safety guard, have pressure limiting valve and the handle above the pressure limiting valve, between the two by being threaded, its design feature is to clamp the safety guard that a cross section is " ∏ " substantially between pressure limiting valve and the handle, and the central authorities of safety guard have through hole.
The shape of described safety guard is truncated cone-shaped, also can be cylindrical, top seal, lower openings.
Described safety guard is a water white transparency.
The beneficial effects of the utility model are: after pressure limiting valve was loaded onto safety guard, gas is discharge below cover just, forms a kind of diffusion, rather than directly is sprayed onto on the person, can reach purpose of safety.In addition, the utility model simple in structure, unpick and wash conveniently, with low cost, outward appearance is beautiful.

The specific embodiment
As shown in the figure, present embodiment has a bakelite or plastic round shaft 2, and the bottom of handle is fixed with screw rod 2-1.The shape of pressure limiting valve resembles a sliding weight of steelyard, and the centre has cavity, and internal thread 1-1 has been attacked on the top of cavity, and the bottom is the counterbore of a circle, has two vertical mutually and connect venthole 1-2 in the middle cylindrical cavity.Clamp safety guard 3 between handle and pressure limiting valve, safety guard is truncated cone-shaped, and the bottom is bigger, the centre has through hole 3-1, during assembling, when the screw rod 2-1 on the handle 2 and the screw 1-1 on the pressure limiting valve 1 tightened, the safety guard 3 that is clipped in the middle just was fixed between the two naturally.The material selection transparent plastic of safety guard, it is beautiful to load onto the back outward appearance, also can in time find behind the internal contamination to clean.
