The timing sound pressure-limiting valve can send out the whistle at the pre-set time and remind people that the time for cooking is up. The pressure limiting valve comprises a valve body and a valve core, and the mechanical timer is installed on the upper part of the valve body. The outer case of the timer and the timing rotary button are provided with time scale and pointers, and the opening pore of the valve core is connected with the air-operated sounding element. When the pre-set time is up, the connecting passage is clear and the air-operated sounding element is forced to make sound by the airflow.
Description
The utility model relates to a kind of limiting valve of pressure cooker.
The cooking time of accurately grasping pressure cooker is necessary.Otherwise, can make the eating effect variation of food, or waste energy.In fact, though on the specification of commercially available pressure cooker with the cooking time of multiple food, people often are difficult to accurately grasp, its main cause is not free prompting.
The purpose of this utility model is, designs a kind ofly to be used for pressure cooker and to have regularly news ringing the pressure limiting valve of function, and it can send audible signal when reaching the time of setting up in advance, and the prompting cooking time arrives.
Technical solution of the present utility model is that it comprises valve body, spool and has the mechanical timer of trough of belt rotating disk and driving lever.Mechanical timer and timing knob are installed in valve body top.Timer seals with diaphragm seal, and regularly knob is fixed on the main shaft of timer, on timer shell and timing knob time scale and pointer is set.An end that has the Kong Bingtong sebific duct on the spool links to each other, and the other end of this sebific duct is connected to the pneumatic sounding component that communicates with atmosphere.The position of described driving lever is, when the slide block on it was on the periphery of described rotating disk garden, the contact block compressing sebific duct on the driving lever made its blocking-up, and when slide block was in the groove of rotating disk, contact block made sebific duct unimpeded.
The utility model is that the mechanical timer in the prior art is applied in the pressure limiting valve, is connected to break-make by the airline hose of the pneumatic sounding component of air-flow sounding by its control, and realizes the course of work.Make below in conjunction with accompanying drawing and to further specify.
Description of drawings: Fig. 1 is external structure and working method schematic diagram, and Fig. 2 is a cut-away view, and Fig. 3 and Fig. 4 are the structure charts that news are rung controlling organization.In described accompanying drawing:
The 1-pressure cooker, 2-valve seat, 3-valve body, 4-high specific gravity material ring set, 5-main shaft, 6-clockwork spring, the 7-gear assembly, the upper and lower clamping plate of 8-, 9-is knob regularly, 10-timer shell, 11-pointer, 12-diaphragm seal, the pneumatic sounding component of 13-, 14-sebific duct, 15-spool, the 16-hole, 17-reed, 18-rotating disk.
In described accompanying drawing, include trough of belt rotating disk (18) and driving lever (19) adopt prior art at interior mechanical timer structure.Referring to accompanying drawing, the utility model comprises valve body (3), spool (15), mechanical timer and timing knob (9) are equipped with in valve body (3) top, and mechanical timer seals with diaphragm seal (12), and described timing knob (9) is fixed on the main shaft of mechanical timer; On timer shell (10) and timing knob (9), corresponding time scale and pointer are arranged.Have hole (16) on the spool (15), an end of its same sebific duct (14) links to each other, and the other end of this sebific duct (14) is connected to pneumatic sounding component (13).The exhaust outlet of described pneumatic sounding component (13) communicates with the atmosphere of pressure limiting valve outer surface.Slide block (23) and contact block (22) are arranged on the described driving lever (19).The installation site of this driving lever (19) is, when slide block (23) was on the garden periphery of described rotating disk (18), contact block (22) the compressing sebific duct (14) on the driving lever (19) made its internal pipeline blocking-up; When slide block (23) was in the groove (20) of rotating disk (18), described contact block (22) made sebific duct (14) unimpeded (promptly cancelling the compressing to sebific duct).In order to guarantee the working stability of pressure limiting valve, be provided with the ring set made from the high specific gravity material (4) in valve body (3) bottom, in order to the center of gravity of reduction valve, and play the counterweight effect.
Operation principle of the present utility model and process are (referring to Fig. 3 and Fig. 4), turn is knob (9) preset time regularly, again valve is withheld on the valve seat (2), slide block (23) on driving lever this moment (19) is on the periphery of rotating disk (18) garden, contact block (22) compressing sebific duct (14), make it not smooth, the steam in the pressure cooker can not pass through sebific duct (14), and element (13) is sounding not.When timing mechanism was gone to the preset time terminal point, described slide block (23) just in time fell into groove (20), made the compressing of contact block (22) releasing to sebific duct (14), and steam arrives pneumatic sounding component (13) through sebific duct (14) in the pot thereby make, and makes its sounding.Clockwork spring driving rotating disk (18) rotation when timer, after making slide block (23) fall into groove (20), along with being rotated further of rotating disk (18), make slide block (23) skid off groove (20) and only touch position limiting pile (21) until it, the pressure limiting valve of this moment is with the identical non-timed pressure limiting valve of common pressure limiting valve function.In fact, as long as do not regulate regularly knob (9), this pressure limiting valve is a common pressure limiting valve.The shape of groove (20) should be designed to make slide block (23) easily to slip into and skid off this groove, and the width of groove is relevant with the phonation time length of sounding component (13).
Utilize above-mentioned timer, can also drive the jingle bell sounding.As long as change described pneumatic sounding component (13) into jingle bell, utilize the elastic force of timer clockwork spring, make its sounding.Can also other mechanical system sounding.This moment just needn't perforate on spool.
The utility model has realized that regularly news are rung function, has dependable performance, characteristics easy to use.
Embodiment: be suitable for the limiting valve of pressure cooker of operating pressure 100KPa 20 minutes a kind of time ratings, valve heavily is 100 grams, and the valve profile is the garden cylindricality, is of a size of φ 40 * 50mm.Time scale (minute) be 0,5,10,15,20, OFF, minimum division value is 1 minute, the non-timed duty of " OFF " expression valve.Mechanical timer adopts the timer of the structure of OFJ20, and overall dimensions is φ 38 * 25, and sebific duct (14) and contact block (22) are 130 ℃ of heatproofs, nontoxic, ageing-resistant rubber material product.Valve body (3) is good by intensity, the light material valve body of heatproof and bottom high specific gravity material ring set (4) constitute, but light material aluminium, electric bakelite, ABS engineering plastics etc., the high specific gravity material can adopt outer surface through antiseptic A3 steel or the inexpensive metal material of other corresponding proportion.Pneumatic sounding component (13) utilizes the acoustical generator of air-flow turbulent fluctuation sounding for resonant wedge whistle or other.
Another embodiment of the present utility model is, opens through hole on timer spindle, and this hole links to each other with spool bore (16), controls break-make between two holes by the effect of linkage.The double sounding component of doing of spindle hole.This structure can be cleaned the duct easily and need not any parts of demolition.
