Description

Technical Field

[0001] The present invention relates to the technical field of portable gas stoves, and in particular to a portable stove valve comprehensive performance detection device and method. Background Art

[0002] Portable gas stoves, also known as portable stoves or cassette stoves, are increasingly being used by restaurants and families. Thanks to the lightweight and portable gas storage cylinders, portable stoves can be placed in various locations without restrictions and are also convenient for outdoor carrying. However, during the use of portable stoves, if the internal pressure of the gas cylinder increases abnormally, the temperature of the stove body increases abnormally, and if the gas appliance cannot be extinguished in time, an explosion accident is likely to occur.

[0003] The invention patent with the patent number "201310689814.6" and the name "Portable gas barbecue with multiple protection functions" mentions an overpressure protection safety device, which will automatically cut off the gas lines on both sides and sound an alarm when an abnormal increase in pressure in the gas cylinder is detected.

[0004] There is also a portable stove on the market with a valve that automatically pops open the gas cylinder when it is over-pressured. The valve includes an air inlet, a magnet and an actuating shaft. The magnet is used to attract the gas cylinder, and the air inlet is used to connect to the mouth of the gas cylinder. When the gas cylinder is connected to the valve, when the gas pressure in the gas cylinder reaches 0.4MPa~0.6MPa, the valve automatically starts the safety actuation procedure. The actuating shaft of the valve can push the boss of the gas cylinder container outward, causing the gas cylinder to fall off the valve, automatically cutting off the gas supply to ensure safety.

[0005] This type of portable stove needs to undergo quality inspection before leaving the factory, especially the inspection of the safe operating performance of the valve. Currently, gas cylinders with higher gas pressure are usually used for testing. If a valve of unqualified quality is encountered, the gas cylinder cannot be opened quickly, which will cause gas leakage and pose a major safety hazard.

[0006] In addition, the pressure-resistant air tightness of the valve also needs to be tested. Unqualified products are prone to leaks at the joints of the valve. The valve needs to be tested for pressure-resistant air tightness under a pressure greater than that of the gas cylinder that pops open. However, often before this pressure value is reached, the test gas cylinder has already popped open, making the test very difficult. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, the valve in the present invention is not the structure of the present invention, and the valve 2 is introduced to illustrate the structure and / or function. It should be understood that the directions or positional relationships indicated, such as up, down, front, back, left, right, etc., are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0035] Reference Figure 1 and Figure 2 The present invention discloses a portable stove valve comprehensive performance detection device, comprising a simulated gas cylinder 3, a sensing plate 35, a sensor 37, a gas storage tank 4, a pressure sensor and a leak detection liquid, wherein the simulated gas cylinder 3 is suitable for being installed in the portable stove 1, and the leak detection liquid is used to be applied around the valve 2.

[0036] See also Figure 3 and Figure 4The simulated gas cylinder 3 includes a bottle body 31 and a bottle mouth 32 installed at the front end of the bottle body 31, the bottle mouth 32 is suitable for connecting to the air inlet 21 of the valve 2, and the bottle body 31 is provided with a plurality of guide rods 33 around the bottle mouth 32, and an adsorption plate 34 is installed at the front end of the guide rod 33, and the adsorption plate 34 is used to attract the magnet 22 of the valve 2 to ensure that the bottle mouth 32 is always connected to the air inlet 21 of the valve 2.

[0037] The sensing plate 35 is used to simulate the boss portion of the gas cylinder container. The sensing plate 35 is slidably mounted on the guide rod 33. An elastic member 36 is arranged between the sensing plate 35 and the bottle body 31. The elastic member 36 can be compressed. The bottle mouth 32 passes through the sensing plate 35 and the adsorption plate 34 from back to front in sequence. The sensing plate 35 can be pushed backward by the actuating shaft 23 of the valve 2. The sensor 37 is installed on the bottle body 31 and is located behind the sensing plate 35. The sensor 37 is suitable for contacting and sensing the sensing plate 35 on the moving path of the sensing plate 35 compressing the elastic member 36. By reasonably arranging the positions of the elastic member 36 and the sensor 37, when a qualified valve 2 automatically pops open due to overpressure, it can compress the elastic member 36 of sufficient length to enable the sensing plate 35 to contact and sense the sensor 37.

[0038] The gas storage tank 4 can be connected to the bottle mouth 32 through the air pipe 5. The gas storage tank 4 can store compressed air or inert gas to ensure safety and no hidden dangers. The pressure sensor is used to detect the air pressure of the air pipe 5.

[0039] During the testing process of the comprehensive performance testing device, the adsorption plate 34 firmly attracts the magnet 22 of the valve 2 to ensure that the bottle mouth 32 is always connected to the air inlet 21 of the valve 2. When the gas filled into the valve 2 by the gas storage tank 4 through the bottle mouth 32 reaches a certain air pressure value, if the actuating shaft 23 of the valve 2 cannot push the sensing plate 35, or the actuating shaft 23 of the valve 2 pushes the sensing plate 35 with a small force that is not enough to compress the elastic member 36 a sufficient distance, the sensor 37 will not be able to contact and sense the sensing plate 35, and it is judged that the valve 2 cannot automatically pop open the gas cylinder and is an unqualified product.

[0040] When the sensor 37 detects contact with the sensing plate 35, the air pressure value in the air pipe 5 at this time can be recorded by the pressure sensor to determine whether the air pressure value is within the qualified range value, so as to determine whether the valve 2 is a qualified product.

[0041] In addition, since the bottle mouth 32 is always connected to the air inlet 21 of the valve 2 and is not affected by the movement of the sensing plate 35, the gas storage tank 4 can also continue to fill the valve 2 with gas. By applying a leak detection liquid around the valve 2, it can be observed whether bubbles are generated, thereby enabling the portable stove valve to be tested for safe actuation performance and durable airtightness at one time, which is convenient and quick, and has no safety hazards.

[0042] See also Figure 1 and Figure 2In some embodiments of the present invention, a pressure chamber 38 is formed inside the bottle body 31, the front end of the pressure chamber 38 is connected to the bottle mouth 32, and the rear end is provided with an input port 39, which can be connected to the gas storage tank 4 through the air pipe 5.

[0043] In some embodiments of the present invention, the present invention further includes a detection unit 6, which is electrically connected to the sensor 37 and the pressure sensor, and can more conveniently record the air pressure value in the trachea 5 when the sensor 37 detects contact with the sensing plate 35. The detection unit 6 can also be more intuitively viewed and transcribed by the detection personnel by additionally connecting to a display.

[0044] See also Figure 3 and Figure 4 In some embodiments of the present invention, the middle of the adsorption plate 34 and the sensing plate 35 are both circular hollow shapes, and the inner diameter of the adsorption plate 34 is larger than the inner diameter of the sensing plate 35, so that the actuating shaft 23 of the valve 2 can pass through the adsorption plate 34 and push the sensing plate 35 without affecting the movement of the actuating shaft 23 of the valve 2.

[0045] Moreover, a stopper 331 is installed on the guide rod 33, and the stopper 331 is located between the sensing plate 35 and the adsorption plate 34. The stopper 331 is used to limit the moving path of the sensing plate 35, and can also separate the sensing plate 35 from the adsorption plate 34 to prevent the sensing plate 35 from being affected by the magnet 22. The elastic member 36 can specifically be a compression spring.

[0046] In addition, in order to facilitate the installation and positioning of the simulated gas cylinder 3, a positioning groove 341 is provided on the outer edge of the adsorption plate 34, and a positioning block is correspondingly provided on the valve 2 to facilitate the one-time insertion of the bottle mouth 32 into the air inlet 21 of the valve 2.

[0047] The present invention also discloses a method for detecting the comprehensive performance of a portable stove valve, which uses the above-mentioned device for detecting the comprehensive performance of a portable stove valve, and specifically comprises the following steps:

[0048] Place the simulated gas cylinder 3 into the portable stove 1, align the bottle mouth 32 with the gas inlet 21 of the valve 2, and make the adsorption plate 34 attracted by the magnet 22 of the valve 2;

[0049] Apply leak detection fluid around valve 2;

[0050] The gas storage tank 4 is connected to the bottle mouth 32 through the air pipe 5;

[0051] Open the gas storage tank 4, so that the gas storage tank 4 gradually fills the gas into the gas inlet 21 of the valve 2 through the bottle mouth 32;

[0052] Detect whether the sensor 37 contacts the sensing plate 35, and if so, record the air pressure value in the air pipe 5 detected by the pressure sensor at that time;

[0053] The gas storage tank 4 continues to gradually fill the gas into the gas inlet 21 of the valve 2 through the bottle mouth 32. When the gas pressure in the gas pipe 5 reaches a preset value, the gas storage tank 4 is closed.

[0054] Check whether there are any bubbles around valve 2.

[0055] This detection method firmly attracts the magnet 22 of the valve 2 through the adsorption plate 34 to ensure that the bottle mouth 32 is always connected to the air inlet 21 of the valve 2. Before inflation, a leak detection liquid is applied around the valve 2 to detect leaks at the joints of the valve 2 throughout the entire process. When the gas filled into the valve 2 by the gas storage tank 4 through the bottle mouth 32 reaches a certain air pressure value, if the actuating shaft 23 of the valve 2 cannot push the sensing plate 35, or the actuating shaft 23 of the valve 2 pushes the sensing plate 35 with a small force that is not enough to compress the elastic member 36 a sufficient distance, the sensor 37 will not be able to contact and sense the sensing plate 35, and it is judged that the valve 2 cannot automatically pop open the gas cylinder and is an unqualified product.

[0056] When the sensor 37 detects contact with the sensing plate 35, the air pressure value in the air pipe 5 at this time can be recorded by the pressure sensor to determine whether the air pressure value is within the qualified range value, so as to determine whether the valve 2 is a qualified product.

[0057] In addition, since the bottle mouth 32 is always connected to the air inlet 21 of the valve 2 and is not affected by the movement of the sensing plate 35, the gas storage tank 4 can also continue to fill the valve 2 with gas. By applying a leak detection liquid around the valve 2, it can be observed whether bubbles are generated, thereby enabling the portable stove valve to be tested for safe actuation performance and durable airtightness at one time, which is convenient and quick, and has no safety hazards.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
