Abstract
The invention discloses a pressure cooker one-way valve, which is installed at the top part of the inner of a jacket of a jacket-mounted pressure cooker and welded to the inner wall of the jacket; the one-way valve is composed of a valve body bolt 11, a valve body 12, a spring 13 and a steel ball 14, wherein the bolt is in threaded connection with the valve body, an exhaust hole is arranged above the center of the bolt and is communicated with a small round hole at the position corresponding to the jacket, an intake port is arranged below the valve body, is covered by the steel ball and jacks the spring above. When the air pressure at the intake port reaches a rated value, the steel ball is jacked and the gas inside the jacket is exhausted out of the cooker through the exhaust hole. The one-way valve according to the invention can ensure the safety of the jacket and no excessive pressure, has heat insulating and preserving efficiency, simple structure and convenient use, and is suitable for the jacket-mounted pressure cooker.
Description
Technical field
The present invention relates to a kind of unidirectional valve, the check valve on particularly a kind of pressure cooker.
Technical background
Check valve is important class in the valve, flows on certain orientation in order to the control fluid.The kind of check valve has many, is medium mostly with compressed air.Application number 200520043396.4, name are called " a kind of unloading one-way valve of air compressor machine " (notification number CN 2802122Y, applying date 2005-07-13), are exactly this type of check valve.Its disclosed check valve, comprise valve body and air inlet pipe joint, inlet chamber and working chamber, inlet chamber communicates with the air inlet pipe joint, and packing ring and seal are arranged at its top, and the off-load mouth is arranged, spool and seal are arranged in the working chamber, connecting rod is arranged, vertical ventilation groove and air inlet duct are arranged on its anchor ring, disappointing groove and limit body are arranged on the connecting rod.When compressor shutdown, can guarantee automatic deloading.It is a kind of of numerous check valves.Check valve as on pressure cooker is not reported at present.
Summary of the invention
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part, and provide a kind of simple in structure, safe and reliable, easy to use, be applied in the pressure cooker one-way valve in the chuck of sandwich interlayer pressure pan.
The object of the invention can reach by following measure:
A kind of pressure cooker one-way valve, it is characterized in that, described pressure cooker one-way valve is placed in a kind of chuck of sandwich interlayer pressure pan, and it includes the valve body bolt, valve body, spring and steel ball are with steam vent in this valve body bolt in the heart, and are welded in the top of above-mentioned chuck inwall with the outer surface of bolt, allow a round tube hole on this steam vent and the chuck end face, on same center line, communicate; Center, above-mentioned body cavity below, a funnel shaped air admission hole is arranged, this air admission hole and above-mentioned steam vent are on same center line and communicate; The screw thread that top at this body cavity is with, be complementary with the valve body bolt, and be connected with the valve body bolt by this screw thread; In body cavity, on above-mentioned funnel shaped air admission hole, be placed with a steel ball, be placed with spring above the steel ball.
The elastic force of above-mentioned spring is set in, and when the air pressure of air admission hole reached 0.3Kpa～0.5Kpa, described steel ball was by jack-up.
Pressure cooker one-way valve of the present invention has following advantage:
1. guarantee the safety of pressure cooker chuck, prevent its superpressure.Pressure cooker can make the air pressure of interlayer raise in heating process simultaneously.When air pressure reached 0.3Kpa～0.5Kpa, check valve automatically lost heart, release, and temperature reduces, and also can have influence on the pressure and temperature in the pot, guarantees that pressure cooker is no more than specified air pressure, makes pressure cooker safety, and is firm.
2. tool is heat insulation, the insulation effect.After the check valve release and discharging unnecessary gas, steel ball falls, and the outer air of pot can not enter in the chuck, and the pressure cooker chuck is in the partial vacuum state, has reduced the convection current of air, and is heat insulation with environment temperature.Like this, pressure cooker can no longer heat and smoldering, plays and exempts from the fire function of Zhu again, reaches efficient, energy-conservation.
3. simple in structure, easy to use.
Below in conjunction with drawings and Examples the present invention is done further non-limiting narration,
Description of drawings
Fig. 1 is a pressure cooker one-way valve of the present invention and pot schematic diagram of body relation;
Fig. 2 is the enlarged drawing of A portion among Fig. 1;
Fig. 3 is the structural representation of pressure cooker one-way valve of the present invention;
Among each figure, the 1st, pressure cooker one-way valve, the 2nd, sandwich interlayer pressure pan, the 11st, valve body bolt, the 12nd, valve body, the 13rd, spring, the 14th, steel ball, the 21st, chuck, the 110th, steam vent, the 111st, the outer surface of valve body bolt, the 120th, air admission hole, the 121st, screw thread.
The specific embodiment
By 2 li of the sandwich interlayer pressure pans with chuck 21 of stainless steel preparation, parts valve body bolt 11 with a pressure cooker one-way valve 1, be welded on the inwall at chuck 21 tops, the outer surface 111 1 whole welding of enclosing the land with bolt 11, the inwall of this bolt and chuck is fused, on the bolt outer surface, do not have the space that can allow air-flow rise; And, the top at this valve body bolt center, be with a little steam vent 110, correspondingly, in the place corresponding, chuck aspect top with bolt, a little round tube hole is also arranged, allowing above-mentioned two apertures on same center line and communicate, promptly is to discharge from steam vent 110 if any the gas in bolt, and can seeing through round tube hole on the chuck, to be discharged to pot external.
Pressure cooker one-way valve of the present invention, be by valve body bolt 11, valve body 12, spring 13 and steel ball 14 are formed, and valve body bolt 11 is connected by screw thread 121 with valve body 12, in the inner chamber that both constitute, place steel ball 14 and spring 13, there is steam vent 110 valve body bolt top, and there is a funnel shaped air admission hole 120 the valve body below, and they communicate up and down; Suppress steel ball by spring, steel ball covers air admission hole 120; The selection of spring can be set at air pressure when 0.3Kpa～0.5Kp, can overcome the elastic force of spring, and with steel ball jack-up, can be discharged to pot from steam vent 110 external for unnecessary gas in the chuck.Check valve of the present invention is applicable on the pressure cooker of strap clamp cover.
