Abstract
The utility model discloses a bimetallic-strip temperature-control valve, which is arranged on a pot cover and is characterized in that a seat body, a pressure-relief tube and a rotary baffle contacting with the pressure-relief tube closely. The end part of the pressure-relief tube is provided with a venting hole, the rotary baffle is provided with a through hole communicated with the venting hole, and a two-way power structure mainly composed of a spring and a bimetallic-strip is connected on the periphery of the rotary baffle. The bimetallic-strip temperature-control valve utilizes the temperature property of the bimetallic-strip to adjust the pressure-relief range inside a pressure vessel and has simple structure, high sensitivity, low cost, safety, stability and good promotional value.
Description
Technical field
The utility model relates to the pressure control equipment technical field, more particularly relates to a kind of valve that can regulate the open-type closure state according to variations in temperature voluntarily.
Background technology
At present, the range of application of pressure-relief valve is extremely extensive, in the prior art, the pressure cooker pressure-relief valve that is used on the cover closing and opening safety device for pressure cooker generally is to be movably set in pot cover surface valve rod, is made of plastic cement upper shield and metal valve body, the fixedly sleeved metal valve body of plastic cement upper shield, valve body is a tubular, and the valve body both sides are connected with upper shield and to be provided with several steam vents, when pot inner pressure acquires a certain degree, jack-up upper shield emission gases reaches the purpose of decompression.Though above-mentioned pressure-relief valve can play the release pressure stabilization function, but in using many problems are arranged, as the steam vent of valve body and the little gas leakage problem between upper shield, little gas leak phenomenon when eliminating the pressure cooker operate as normal, a cavity is arranged between the air admission hole of spool and the venthole, be provided with ball in the cavity, and the diameter of ball is greater than the diameter of air admission hole outlet, a pot internal gas pressure is risen, to improve the operating efficiency of pressure cooker rapidly.But, be subject to the external atmosphere pressure influence because existing pressure-relief valve all is by air pressure control.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy to adjust, and can be by temperature controlled valve.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of bimetal leaf temperature control valve, be arranged on the pot cover, it is characterized in that: it comprise pedestal, relief tube and with its butterfly that closely contacts, the end of relief tube is provided with steam vent, butterfly is provided with through hole and communicates with steam vent, and the periphery of butterfly is connected with the two-way dynamic structure that mainly is made of spring and bimetal leaf.
As further specifying of such scheme, described pedestal and pot cover connect as one by fixture, are provided with cavity between pedestal and the pot cover, relief tube and all be arranged on this cavity inside with its butterfly that closely contacts.
Described pedestal is provided with the through hole that is complementary with relief tube, and the junction of relief tube and pedestal through hole is embedded with sealing ring.
Described pot cover surface is provided with rotating shaft, and butterfly is socketed in the rotating shaft, and spring and bimetal leaf lay respectively at the both sides of rotating shaft.
Described butterfly is irregularly shaped plate, and a side direction of butterfly is protruded outward and joined with the bimetal leaf plane.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the two-way dynamic structure that the utility model adopts spring and bimetal leaf to constitute drives butterfly and rotates, through hole on the butterfly is communicated with relief tube or closure, utilize the temperature characterisitic of bimetal leaf bending to come inner pressurising of pressure of pressure vessel or release with variation of temperature, compared with prior art, have the function that temperature control plays pressure or release, cooperate pressure cooker to use the cooking method that can reach unique.

The specific embodiment
As Fig. 1～shown in Figure 3, a kind of bimetal leaf temperature control of the utility model valve is arranged on the pot cover 1, comprise pedestal 2, relief tube 3 and with its butterfly that closely contacts 4, pedestal 2 connects as one by fixture 5 with pot cover 1, and fixture 5 can be adopted as screw or pin.Be provided with cavity between pedestal 2 and the pot cover 1, relief tube 3 and all be arranged on this cavity inside with its butterfly that closely contacts 4, the end of relief tube 3 is provided with steam vent 6, pedestal 2 is provided with the through hole 7 that is complementary with relief tube 3, relief tube 3 is embedded with sealing ring 8 with the junction of pedestal through hole 7, butterfly 4 is provided with through hole 9 and communicates with steam vent 6, the periphery of butterfly 4 is connected with the two-way dynamic structure that mainly is made of spring 10 and bimetal leaf 11, pot cover 1 surface is provided with rotating shaft 12, butterfly 4 is socketed in the rotating shaft 12, spring 10 and bimetal leaf 11 lay respectively at the both sides of rotating shaft 12, butterfly 4 is irregularly shaped plate, one side direction of butterfly 4 is protruded outward and is joined with bimetal leaf 11 planes, wherein, bimetal leaf 11 mainly by the different two kinds of alloy pressings of the coefficient of expansion together, be respectively active layers and passive layer, when temperature raises, it is more than passive layer that active layers expands, make the sheet metal bending, baffle plate rotates UNICOM or blocks relief tube, realizes driving the purpose that pressure-relief valve opens or closes.
In the use, under the normality, the butterfly through hole makes pressure cooker inside and exterior over against steam vent, is in exhaust condition; After pressure cooker is heated, the bimetal leaf bending, butterfly is subjected to the pulling force of spring to forward the sealed porosity state to, makes the pressure cooker inner sealing.
The utility model is not limited to the foregoing description, as Fig. 4, shown in Figure 5, under the normality, pressure cooker can also adopt the sealed porosity state except being set to exhaust condition, pressure cooker is heated after, the bimetal leaf bending, butterfly is forwarded to by spring tension and makes the position of through hole over against steam vent, and pressure cooker inside and exterior are in exhaust condition.
