Abstract
The utility model relates to an over pressure safety dynamic and static sealed directional air deflating valve, which is composed of an air deflating valve, a restoring spring, a top rod, an elastic shim, a silica gel valve seat body and a valve core. The utility model is characterized in that the silica gel valve seat body is provided with a bayonet and is arranged on a sealed container through the bayonet, the valve seat body is provided with a sealed upper mouth and a sealed lower mouth, and air discharging holes are arranged between the sealed upper mouth and the sealed lower mouth; the sealed upper mouth of the silica gel valve seat body is provided with an air deflating button assembly which is composed of the air deflating button, the restoring spring, the top rod and the elastic shim. The sealed lower mouth of the silica gel valve seat body is assembled with the valve core which is packaged with an air outlet hole of the valve core which blocks a working table of an air valve and an air overpressure step.
Description
The utility model relates to the air valve of pressure cooker, specifically is used for the directed bleed valve of superpressure insurance static and dynamic sealing of pressure cooker.
What present various pressure cooker was installed is " heavy hammer type cone valve ", not only uses dangerously, and the design of this valve arrangement is unreasonable, uses inconvenience.
The purpose of this utility model provides a kind ofly to be had from static and dynamic sealing, automatically motive sealing, the exit pressure cooker air valve of function of directed venting and superpressure insurance, and it is simple in structure, and is easy to use.
The purpose of this utility model realizes by following proposal, the directed bleed valve of superpressure insurance static and dynamic sealing of the present utility model comprises a silica gel valve body that is installed on the seal container (as pressure cooker lid), this valve body has a bayonet socket, be installed on the seal container by bayonet socket, this valve body has the suitable for reading and sealing end opening of a sealing, and the discharging pore arranged between it, at the silica gel valve body sealing venting button assembly that is equipped with suitable for reading, be equipped with spool at silica gel valve body sealing end opening, described venting button assembly is by the venting button, Returnning spring, push rod and compression spring are formed, described spool includes the spool air outlet hole, valve core sealing valve working bank and spool gas shutoff superpressure step.
The utility model has the advantages that and can realize from static and dynamic sealing, motive sealing automatically, directed venting, four kinds of functions of superpressure insurance venting, simple in structure, install easily, promptly cost is low again for safety.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail, wherein:
Fig. 1 is a schematic representation of the present utility model.
Now referring to accompanying drawing, the directed bleed valve of superpressure insurance static and dynamic sealing of the present utility model mainly comprises venting button (1), Returnning spring (2), push rod (3), compression spring (4), silica gel valve body (11), and spool (15).
Wherein compression spring (4) is sleeved on earlier on the push rod (3), and then Returnning spring (2) is enclosed within on the push rod (3) that compression spring (4) are housed, be connected with compression spring (4) and be fixed together by venting button (1), form one independently " venting button assembly ".(5) insert silica gel valve body top (6) in this " venting button assembly " being gone up from the sealing of silica gel valve body again, to reach and silica gel valve body (11) purpose of connecting; Spool (15) upwards inserts in the silica gel valve body (11) from silica gel valve body end opening (14), is connected with silica gel pedestal (11) simultaneously, and can reaches the purpose of easy on and off activity.
During use,, insert the mount inlet (being in the circular hole of a 16.5MM at nutrition pot pot cover center) of seal container (17), reach the flexible sealing purpose of connecting by valve seat technology bayonet socket (12) with silica gel valve body (11).The moment of in pot, seething with excitement, the firm hot steam who produces, do not having under the situation of pressure, the hot steam rises, the cool air of getting rid of space stochastic storing in the pot, by the spool (15) that blows very light weight, and in silica gel valve body (11) bob, destroying spool (15) falls because of gravity, rest silica gel valve body sealing end opening (14) and go up " static seal " state that causes, cool air in the pot is in the slit that moment is provided during promptly with spool (15) bob, flows to silica gel valve seat discharging pore (8) and silica gel valve seat discharging gas port (9) and outside directed discharge pot.When pot inner pressure progressively raises, cool air is all discharged, when reaching complete fluidized state, spool (15) is gone up fully and is jumped, valve core sealing valve working bank (19) is clamped by silica gel valve body sealing end opening, at this moment enter stop in " hermetically sealed " state pot the boiling, when pot inner pressure reaches setting value, cut off the electricity supply automatically, enter keeping warm mode, be edible after 8-10 minute, surpass setting value, the then unable valve core sealing valve working bank (19) of clamping of silica gel valve base sealing end opening (14) as working pressure, then move to the position of valve core sealing valve superpressure step (18) on the spool (15), malfunctioning as pot internal control temperature control pressure device, pressure up raises again, when reaching the superpressure warning, at this moment spool (15) then pours in the silica gel valve body (11), reach the purpose of " superpressure insurance venting ", this function has not only been saved " fuse sheet " of commercially available pressure cooker, and it is more reliable than " fuse sheet ", more insurance, cost is lower, uses more convenient.
When spool (15) is influenced by gravity, when freely dropping down onto silica gel valve base sealing mouth (14), then realized " static seal " effect; Influence when spool (15) is subjected to a pot internal air pressure, when last jumping is blocked or clamped by valve core sealing valve working bank (19), realized automatic pneumostop effect, i.e. " motive sealing " function; Under " motive sealing " situation, moving venting button (1) press...withes one's finger, push rod (3) promotes spool (15) and moves down, by spool air outlet hole (16) and the gap at spool (15) middle part and the purpose that silica gel valve seat discharging gas port (8) and (9) reaches directed venting pressure release of spool (15).The sealing upper and lower opening of valve body can be made by flexible material.
Claims (1)
1, the directed bleed valve of a kind of superpressure insurance static and dynamic sealing, by the venting button, Returnning spring, push rod, resilient pad silica gel valve body and spool are formed, it is characterized in that the silica gel valve body has a bayonet socket, be installed on the seal container by this bayonet socket, this valve body has the suitable for reading and sealing end opening and the discharging pore is arranged of a sealing between it, seal suitable for reading being equipped with at the silica gel valve body by the venting button, Returnning spring, the venting button assembly that push rod and resilient pad are formed, be equipped with spool at silica gel valve body sealing end opening, described spool is surrounded by the spool air outlet hole, valve core sealing valve worktable and spool gas shutoff superpressure step.
