Description
Technical field
The present invention relates to a kind of pressure cooker, relate in particular to a kind of limiting valve of pressure cooker.
Background technology
Limiting valve of pressure cooker is installed on the blast pipe of pressure cooker lid, by the pressure in the limiting valve of pressure cooker energy limiting pressure pot.During use, first regulate as required rated pressure, when the air pressure in the pressure cooker reaches this rated pressure, will overcome the spring force in the limiting valve of pressure cooker and spool jack-up is come, then the steam in the pressure cooker is just by the blast pipe exhaust that makes progress.But the spool head of common pressure cooker withstands the exhaust outlet of blast pipe upper end, lack reliable guiding mechanism, in long-term use procedure, spool back and forth moves up and down, the axis generation deviation that can cause axis and the blast pipe of spool, thereby cause producing the gap between spool head and the exhaust pipe mouth and leaking gas, thereby cause the interior pressure transient of pressure cooker, impact culinary art effect; Steam is upwards exhaust from the gap of the head of spool and blast pipe upper end open, can be subject to the resistance of spool, capacity is little, in the process of exhaust, pressure in the pressure cooker still can continue to rise last above rated pressure, common limiting valve of pressure cooker will have potential safety hazard like this, so can't be controlled pot inner pressure accurately.
Chinese patent Granted publication number: CN201861422U, June 15 2011 Granted publication day, a kind of limiting valve of pressure cooker is disclosed, comprise valve body, needle and plastic jacket, valve body is tubular and is made by metal material, plastic jacket is coated on the outer wall of valve body, valve body is equipped with the plastic barrel that is complementary with its inwall, be provided with the permeation sheet between the end of valve body and the plastic jacket, needle is connected mutually with the permeation sheet and needle is positioned at valve body, have air bleed on the permeation sheet, plastic jacket has the opening corresponding with described air bleed.This limiting valve of pressure cooker can not get rusty, sanitation degree high and process easy for installation.Its weak point is that spool and the blast pipe of this kind limiting valve of pressure cooker lacks reliable guiding mechanism, in long-term the use, the axis of spool and the axis of blast pipe produce deviation and cause the poor and gas leakage of sealing, gas leakage can cause again pot inner pressure unstable, capacity is little during simultaneously exhaust, and the pressure in the exhaust process in the pressure cooker still rises and surpasses rated pressure, can not accurately control pot inner pressure, there is potential safety hazard in impact culinary art effect.
Summary of the invention
The present invention causes gas leakage for the spool that overcomes pressure cooker of the prior art produces deviation in long-term use procedure and between the blast pipe axis, capacity is little simultaneously can not accurately control the deficiency that effect is cooked in the pot inner pressure impact, a kind of good seal performance is provided, can accurately control pot inner pressure, cook effective, safe and reliable limiting valve of pressure cooker.
To achieve these goals, the present invention adopts following technical scheme:
A kind of limiting valve of pressure cooker, being arranged on pressure cooker covers, comprise valve body and the pressure limiting valve cover that is located at the outside, valve body upper end, be provided with blast pipe in the described valve body, stretch out outside the valve body lower end of described blast pipe, be provided with spool in the described blast pipe, the outside of described blast pipe is arranged with fairlead, the upper end of described fairlead is connected with spool, be provided with valve pocket in the described valve body, be provided with spring between described valve pocket and the fairlead, the corresponding position of sealing place of the side of described blast pipe and spool head and blast pipe is provided with the gas outlet.Fairlead can guarantee that spool and blast pipe are coaxial, can guarantee that like this sealing is reliable between the head of spool and the blast pipe, can not leak gas during use, when the pressure in the pot reaches the force value of setting, air pressure overcomes the active force of spring, the jack-up spool, gas outlet exhaust from exhaust pipe side face, the gas outlet of exhaust pipe side face is larger than the capacity of common limiting valve of pressure cooker top vent, air pressure in the pressure cooker can not continue because capacity is little to rise like this, can not surpass the pressure of setting, cook effective, simultaneously safer, reliable yet.
As preferably, the aperture of described blast pipe upper end is greater than the aperture of lower end, the step place press seal that the head of described spool and blast pipe are interior.The upper port place sealing of common spool and blast pipe, and spool stretches in the blast pipe in this structure, spool self has guide effect, can guarantee that spool and blast pipe are coaxial, thereby guarantees the good seal performance at spool head and blast pipe step place.
As preferably, described spool and blast pipe matched in clearance, described fairlead and blast pipe matched in clearance.Spool and fairlead respectively with inboard and the outside matched in clearance of blast pipe, guaranteed that spool is more stable, smooth and easy when moving up and down, also further guaranteed the coaxial distribution of spool and blast pipe, good seal performance simultaneously.
As preferably, the contact-making surface at the step place in the head of described spool and the blast pipe is sphere.Sphere contacts with the circular hole at step place in the blast pipe, even the axis between spool and the blast pipe has some deviations also can guarantee sealing, the space, both sides in slit is large during simultaneously exhaust, and is little to the resistance of steam, capacity is larger, thereby guarantees that the pressure in the pot can not exceed the rated pressure of setting.
As a kind of scheme arranged side by side, the contact-making surface at the step place in the head of spool and the blast pipe is taper seat.In the time of valve core reset, taper seat has a guide effect, the axis of energy guide spool and the axis coaxle of blast pipe, and sealing effectiveness is better.
As preferably, described fairlead and described spool are the integral type structure.Fairlead and spool integral structure intensity are large, and axiality is good.
As preferably, be provided with cavity in the described spool.Cavity can reduce the quality of spool, thereby reduce the inertia that it moves up and down, spool opens and closes more responsive, quick under the effect of air pressure, reduce simultaneously the kick that spool falls after rise under spring action, prevent that effectively sealing place from affecting sealing property because the effect of long-term kick is worn and torn, is out of shape.
As preferably, stretch out outside the valve body upper end of described valve pocket, the both sides of described valve pocket upper end are provided with projection, the upper surface of described projection is inverted V-shaped, the circumference at the diameter place corresponding with projection is provided with two about the centrosymmetric adjustable ring in the center of circle in the described pressure limiting valve cover, be respectively left adjustable ring and right adjustable ring, the end face of described left adjustable ring is provided with the tooth corresponding with the projection upper surface, and the height of described left adjustable ring passes through and raises gradually.By rotation pressure limiting valve cover, regulate the height of valve pocket, thereby regulate the force value of decrement to realize that setting is different of valve pocket inner spring.
Therefore, the present invention has good seal performance, can accurately control pot inner pressure, cooks effective, safe and reliable beneficial effect.
