Abstract
The utility model discloses a safety pressure limiting valve for pressure cookers, which is composed of a valve body, a valve bonnet and a limiting plate, wherein, the valve body is fixed on a cooker lid and is a hollow column body which forms an exhaust pipe, and the middle part of the valve bonnet is provided with a core rod of which the outside diameter is smaller than the inside diameter of the valve body. The limiting plate is fixed on a cooker wall, and the middle part of the limiting plate is provided with a circular hole; the core rod on the valve bonnet penetrates through the valve body and the limiting plate. When in use, sundries in the valve body can be certainly eliminated by the insertion inserted and the rotation of the core rod, ensuring smooth air exhaust and having no need of a plug preventing cover, and thereby, the pressure cooker has the advantages of easier cleaning, simple structure safe operation, and high reliability.
Description
The utility model relates to a kind of culinary art pressure cooker, relates in particular to a kind of pressure limiting valve structure of pressure cooker.
Pressure cooker is subjected to user's welcome with its advantage such as energy-conservation, quick, but security is the puzzlement user and the producer's a major issue all the time, and the accident that is caused by pressure cooker happens occasionally.At present, the pressure cooker pressure-reducing valve be generally top cap type, pressure limiting valve is made up of valve body and valve gap, valve body is fixed on the high-pressure pot cover, and valve gap is enclosed within the valve body upper end, stops up valve body for avoiding foreign material, also a filtering screen must be set in the valve body bottom, difficulty during cleaning, particularly blast pipe is elongated, more is difficult to clean.If blast pipe is blocked, the user also do not know, can only wait pressure in the pot to rise after, the passive exhaust of safety valve guarantees safety, and certain danger is arranged.And some does not have stopping means existing pressure cooker, and pressure limiting valve does not take off as yet sometimes, just opens pot cover, and the interior hypertonia of pressure cooker this moment can be caused danger.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can play safety valve and stop simultaneously, and clean, use simple novel pressure limiting valve.
The purpose of this utility model is achieved in that designing a kind of pressure limiting valve is made up of valve body, bonnet, limiting plate; Valve body is fixed on the pot cover, and valve body is that hollow cylinder forms blast pipe, and the bonnet middle part is provided with a plug, and the external diameter of plug is less than the internal diameter of valve body, and limiting plate is fixed on pot wall, and there is a circular hole at the limiting plate middle part; During use, the plug on the bonnet passes valve body and limiting plate.
It is inclined hole that bonnet described in the utility model is provided with steam vent, and its axis can promote bonnet and rotate not by the center of circle of bonnet during exhaust.
Valve body described in the utility model is installed in the edge of pot cover.
Owing to take said structure, during use, the plug of pressure limiting valve is inserted in the valve body, and it is shorter that valve body can be done.When the water in the pot seethed with excitement, gas was discharged by the annulus between valve interior wall and the plug.Because gas passage is annular, when having only plug space all around to be plugged simultaneously, the exhaust passage just can be blocked.Single object can not block gas passage.During exhaust, plug ceaselessly rotates, vibrates, and it is shorter to add upper valve body.So the possibility that the exhaust passage is blocked during use is very little.Emerge if heating loses gas the long period, suspect when the exhaust passage is blocked, can guarantee that the exhaust passage is unobstructed as long as change pressure limiting valve.Even the exhaust passage is plugged.Because an end of plug is in pot, along with the pot internal gas pressure progressively increases, the pressure that gas acts on this termination also progressively increases, and backs down pressure limiting valve the most at last.At this moment, pressure limiting valve plays safety valve simultaneously.And the water in the pot generally is that the center from pot up emits, and is fallen after rise by the pot limit again, and valve body is arranged on the pot cover edge, has reduced the chance of directly being impacted by water, has also reduced blocked chance.
Before opening pot cover, must take off pressure limiting valve earlier.Otherwise it is motionless that pot cover changes, and do not open.After getting the limit pressure limiting valve, the gas in the pot communicates with atmosphere, and the air pressure in the pot equals atmospheric pressure, has guaranteed personal safety.Adjust the internal diameter of blast pipe, the diameter of plug and the weight of pressure limiting valve and just can set the pressure of pot interior gas.When the utility model used, when plug inserted and rotates, nature was disposed the foreign material in the valve body, guaranteed that exhaust is unobstructed.And do not need Anti-stop cover, make pressure cooker be easier to clean.Simple in structure, safe in utilization, reliability is high.
Reaching embodiment in conjunction with the accompanying drawings is further described the utility model:
Accompanying drawing 1, the utility model example structure schematic diagram;
Accompanying drawing 2, the utility model embodiment limiting plate structural representation;
Accompanying drawing 3, the utility model embodiment bonnet B-B profile;
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the utility model pressure limiting valve is made up of valve body (2), bonnet (1), limiting plate (5).Valve body (2) is fixed on the pot cover (3) by nut (4), and valve body (2) forms blast pipe for hollow cylinder; Bonnet (1) middle part is provided with a plug (13), and the external diameter of plug (13) is less than the internal diameter of valve body (2); Limiting plate (5) is fixed on pot wall (6), and there is a circular hole (51) at limiting plate (5) middle part; Steam vent (12) on the bonnet (1) is an inclined hole, and its axis does not pass through the center of circle of bonnet (1).
During use, bonnet (1) upper shield is at the top of valve body (2), and the plug (13) in the bonnet (1) passes valve body (2) and limiting plate (5).Fluid temperature in pressure cooker raises, and when reaching certain pressure, upwards promotes plug (13), and gas by the annulus between valve body (2) inwall and the plug (13) is upwards discharged by the steam vent (12) on the bonnet (1).Can promote bonnet (1) during exhaust rotates.
Claims (3)
1, a kind of pressure cooker safety-type pressure limiting valve is characterized in that: be made up of valve body, bonnet, limiting plate; Valve body is fixed on the pot cover, and valve body is that hollow cylinder forms blast pipe, and the bonnet middle part is provided with a plug, and the external diameter of plug is less than the internal diameter of valve body, and limiting plate is fixed on pot wall, and there is a circular hole at the limiting plate middle part; Plug on the bonnet passes valve body and limiting plate.
2, pressure cooker safety-type pressure limiting valve according to claim 1, it is characterized in that: it is inclined hole that described bonnet is provided with steam vent, its axis is the center of circle by bonnet not.
