Abstract
The utility model belongs to an explosion-proof fast decompression safety device for a pressure cooker, which is composed of a valve core (1) and a rubber valve body (2), wherein the middle of the valve body is provided with a core hole (21), and the valve core is composed of a valve cap (11), a valve stem (12), a top shoulder (13), a connecting rod (14) and a clamping element (15). The valve core is positioned in the core hole, and the valve body, the valve core and a valve mounting hole of a cooker cover form resilient seal under the normal condition. When a vent hole is blocked and the pressure in the pressure cooker reaches to the safe pressure, the valve core rises and generates a gap with the core hole to reduce the pressure; when the pressure in the pressure cooker reaches to the pressure of decompression, the valve body is extruded out the cooker cover because of elastic deformation, and the pressure is greatly discharged through the valve mounting hole, so the pressure cooker can be used safely.
Description
(1) technical field: the utility model belongs to the pressure cooker critical piece, especially a kind of safety device of explosion-proof quick pressure releasing.
(2) background technology: pressure cooker is Modern Family's cooker commonly used.The safety device of existing pressure cooker mostly adopts Anti-stop cover, spring safety valve and spring alarm valve.Less because of its passage, if not noting cleaning then stops up easily, spool also gets rusty easily and malfunctioning in the use.Usually because of maloperation or in time clean and produce hidden danger, and the pressure cooker annex increases, complex structure, brings inconvenience to operation and maintenance.
(3) summary of the invention: the purpose of this utility model is exactly provide at the deficiency of above-mentioned safety device a kind of can be not blocked, can finish pressure release rapidly, and simple in structure, the explosion-proof quick pressure releasing device of pressure cooker easy to use.
The utility model is made up of rubber valve body and spool, it is characterized by: the periphery of rubber valve body has a cannelure, and the valve installing hole on cannelure and the pot cover is the elastic packing state, and a core hole is arranged in the centre of rubber valve body, and below, core hole is provided with cavity; Spool is made up of the bonnet that is arranged in order, valve rod, top shoulder, connecting rod and fastener, and fastener can be a claw, also can be chuck with holes, bonnet, valve rod, top shoulder and the design of connecting rod disjunctor, and fastener is fixedlyed connected with connecting rod; Valve rod and core hole adapt, and the top shoulder is greater than the core hole and be arranged in cavity, and connecting rod is then less than the core hole, and the effective diameter of fastener is greater than the diameter of the valve installing hole on the pot cover.
The utility model has advantages such as performance simple in structure, easy to use, safe is good, is suitable for various pressure cooker to install and use, and can replace existing safety valve and alarm valve.
(4) description of drawings: Fig. 1 is the structure principle chart of explosion-proof quick pressure releasing valve.
Fig. 2 is the schematic diagram when being used in pressure cooker and being in normal operating conditions.
Schematic diagram when Fig. 3 is equivalent to the safe pressure state for pot inner pressure.
Schematic diagram when Fig. 4 is equivalent to the pressure release pressure state for pot inner pressure.
Among the figure, 1, spool 2, valve body 3, pot cover 11, bonnet 12, valve rod 13, top shoulder 14, connecting rod 15, claw 21, core hole 22, cannelure 23, cavity 31, valve installing hole.
(5) specific embodiment: with reference to accompanying drawing, this explosion-proof quick pressure releasing valve is made up of spool 1 and valve body 2, valve body 2 is made by rubber, its periphery is provided with a cannelure 22, when this valve is assemblied in pot cover 3, form the elastic packing state with its valve installing hole 31, a core hole 21 is arranged in the centre of valve body 2, below, core hole is provided with cavity 23.Spool 1 is made up of the bonnet 11 that is arranged in order, valve rod 12, top shoulder 13, connecting rod 14 and claw 15, and except that claw, the equal disjunctor design of the other parts of spool can be processed by metal such as aluminium, and claw 15 can link to each other with connecting rod 14 by the method for riveted joint.Valve rod 12 adapts with core hole 21, under normal circumstances become the elastic packing state, top shoulder 13 is greater than core hole 21, under normal circumstances be arranged in cavity 23, the diameter of connecting rod 14 is less than core hole 21, the fastener of present embodiment is chosen claw, and claw 15 is established three altogether, and its effective diameter is greater than the diameter of the valve installing hole 31 on the pot cover 3.
Its operation principle is as follows: when pressure cooker under design work pressure during normal the use as shown in Figure 2, the 31 one-tenth sealing states of valve installing hole on 21 one-tenth sealing states of spool 1 and valve body core hole, the cannelure 22 of valve body 2 and pot cover 3; When blast pipe blocked for some reason, when pot inner pressure is equivalent to safe pressure (112-160KPa) as shown in Figure 3, when pot inner pressure reaches this pressure, the valve rod 12 of spool and top shoulder 13 are extruded the upper surface of valve body 2, claw 15 is blocked in the lower edge of cavity 23, owing to core hole 21 forms the gap greater than connecting rod 14, the interior gas of pot this moment is drained (shown in A) from this gap and is reduced pressure, realize purpose of safety, at this moment, should turn off burning things which may cause a fire disaster, open pot cover, clean blast pipe,, reuse valve core reset; When pot inner pressure is equivalent to pressure release pressure (160-280Kpa) as shown in Figure 4, if firepower is too quickly, in the time of can't alleviating pot inner pressure by connecting rod 14 with the gap exhaust in core hole 21,2 of rubber valve bodies produce strain, be extruded the pot cover plane together with spool, this moment, the pot internal gas pressure will be from 31 big flow (shown in the B) pressure releases of the valve installing hole on the pot cover, and the pot internal gas pressure is reduced to below the 5Kpa in 5 seconds, thereby moment is finished pressure release, guarantees safe in utilization.Because the effective diameter of claw is greater than the diameter of valve installing hole 31, when valve body is extruded the pot cover plane, claw 15 be stuck in pot cover valve installing hole 31 below, avoid relief valve to fly out pot cover and lose or hurt sb.'s feelings.
