Abstract
The safety control valve for high pressure cooker has structure comprising valve seat and valve cap, and features that the valve seat and the valve cap are fitted or limited via screw structure and this lays the foundation for enlarging the bore of the vertical exhaust hole. After the valve cap is screwed on the valve seat completely, the valve cap is in free state without screw limitation to cover the vertical exhaust hole in the top of the valve seat and to control pressure inside the cooker gravitationally. Owing to the blocking of the outside expanded thread, the valve cap will not be push out from the valve seat by the high pressure vapor inside the cooker. The valve cap may be detached for cleaning through first raising and then screwing in the opposite direction.
Description
Technical field:
The present invention relates to the pressure valve structure technology and the dismounting using method thereof of family expenses pressure cooker cooker.
Background technology:
The pressure valve version that pressure cooker adopts is varied: have free-hand non-removable, have free-hand detachable (circlip type), the former in time removes in booty inconvenience, the latter does not have strong position-limit mechanism to valve gap, if enlarge the aperture (this measure is to solve the key that is difficult for blockage problem) of venthole on the valve seat by the gravity that increases valve seat, its jump ring can't guarantee valve gap not by pot inner high voltage steam with its valve seat that blows off.For this reason, pressure valve is being provided with under the prerequisite of small-bore venthole, also must set up at least the second auxiliary cover (locating) safe pressure valve (facility).
Summary of the invention:
The present invention is a kind of improvement to circlip type pressure control air valve, desires to reach the purpose that can deal with problems once overlapping is set.
To achieve these goals, intend adopting following technology:
Structure of the present invention: it is made of valve seat and valve gap, and the A. valve seat is provided with bore greater than 4 millimeters of vertical ventholes, and the outside protruding part of its top periphery is provided with outer convex thread; B. valve gap top week side is provided with a plurality of horizontal pores, and the inside protruding part of its underpart periphery is provided with interior convex thread.---the said two devices screw thread forms the screw fit structure of a pair of same specification, in addition, establishes the pressure micromatic setting no longer in addition at valve seat or above the valve gap.
Using method of the present invention: A. covers valve gap on valve seat, the valve gap that turns clockwise then, and up to its (the screw thread position of said two devices breaks away from fully) till the precession again, valve gap promptly assembles and finishes, and is in dormant state.B. valve gap is mentioned, make the screw thread position of said two devices join, be rotated counterclockwise valve gap then, till it screwed out the valve seat top, valve gap was promptly dismantled and is finished, and afterwards, just can clean valve gap and valve seat.
The present invention's characteristics compared with the prior art:
1. because the outer convex thread on valve seat top to the position-limiting action of the interior convex thread of bonnet lower, has all been created condition for allowing the venthole bore to enlarge and make gravity pressure control valve gap can not blown out valve seat by gases at high pressure.
2. again because can free-hand easily dismounting between valve seat and valve gap and it is cleaned, and then have been created condition again by dirty stifled possibility zero the degree of being reduced to for this valve gear.
Description of drawings:
Figure has illustrated one embodiment of the present of invention.
A: valve seat; B: valve gap; 1: the horizontal venthole of valve gap; 2: outer convex thread; 3: interior convex thread; 4: pot cover; 5: the vertical venthole of valve seat; 6: dog screw.
The specific embodiment:
Valve seat among the present invention (A) is positioned on the pot cover (4) of pressure cooker by dog screw (6) or alternate manner, the present invention is by valve seat (A) and the two formation of valve gap (B): wherein outside the top of valve seat (A) in the bottom of convex thread (2) and valve gap (B) convex thread (3) form the screw fit structure of a pair of same specification, from top to bottom screw out outer convex thread (3) position of valve seat (A) when valve gap (B) clockwise direction after, whole valve gap (B) promptly is in the free state that non-screw pins down, and because the gravity effect, valve gap (B) just in time covers the vertical venthole (5) at valve seat (A) top.At this moment, since outer convex thread (2) stop that valve gap (B) can't shirk out from valve seat (A).
When the atmospheric pressure in the pressure cooker surpasses a certain numerical value of regulation, gases at high pressure promptly can overcome the gravity of valve gap (B) and it is backed down, is the gases at high pressure that 5 to 6 millimeters of vertical ventholes (5) are discharged from valve seat (A) aperture, passes through aperture on the valve gap (B) again and be 3 millimeters the peripherad airspace of two horizontal ventholes (1) and discharge.
When desire washing is of the present invention, only need free-hand valve gap (B) to be mentioned, just be easy to can outer convex thread (2) coupling with wherein interior convex thread (3) and valve seat (A) on, it can be screwed out valve seat (A) through being rotated counterclockwise.Afterwards, can clean valve seat (A) and valve gap (B) easily, to stop the blocked possibility of the present invention.
Claims (4)
1. the dismountable gravity spacing-type pressure control air valve of an adapted pressure cooker, it is by the valve seat that sets out pore (5) on the axis (A), and the valve gap (B) that top week side sets out pore (1) constitutes, and it is characterized in that:
The outside protruding part, top of valve seat (A) is provided with outer convex thread (2), the inside protruding part, bottom of valve gap (B) is provided with interior convex thread (3), and outer convex thread (2) and interior convex thread (3) just in time form the screw fit structure of a pair of same specification, in addition, do not establish the pressure micromatic setting in addition at valve seat (A) or above the valve gap (B).
2. assembly method of the dismountable gravity spacing-type pressure valve of adapted pressure cooker according to claim 1 is characterized in that:
Described valve seat (A), the bore of vertical venthole (5) wherein is equal to or greater than 5 millimeters.
3. assembly method of the dismountable gravity spacing-type pressure valve of adapted pressure cooker according to claim 1 is characterized in that:
Valve gap (B) is covered on valve seat (A), and the valve gap (B) that turns clockwise then is up to it again till the precession.
4. method for dismounting of the dismountable gravity spacing-type pressure valve of adapted pressure cooker according to claim 1 is characterized in that:
(B) mentions with valve gap, treat that outer convex thread (2) on interior convex thread (3) and the valve seat (A) wherein joins after, another mistake hour hands rotation valve gap (B) is till its screws out valve seat (A) top.
