Description

Technical Field

[0001] This utility model relates to the field of plug valve technology, and in particular to a plug valve based on stir-frying. Background Technology

[0002] This application is mainly for the optimization and improvement of the product involved in the Chinese utility model patent with publication number CN 222102827 U.

[0003] This utility model patent discloses a gas valve and a gas stove. The gas valve can increase the firepower of the inner ring of the burner and decrease the firepower of the outer ring, thereby improving the heating efficiency of the center of the pot in the stir-fry mode and preventing the bottom of the pot from burning dry. On this basis, the oxygen demand of the outer ring is reduced, and more oxygen can be supplied to the inner ring, making the combustion of the inner ring more complete and reducing the concentration of flue gas.

[0004] However, in actual use, because the solenoid valve is directly and vertically installed on the outer ring vent pipe, when the solenoid valve is closed, the valve shaft and the sealing plug at the front end of the valve shaft are vertically located in the outer ring channel of the outer ring vent pipe. Thus, when the gas flows through the outer ring channel, although the outer diameter of the valve shaft and the sealing plug at the front end of the valve shaft is smaller than the inner diameter of the outer ring channel, the gas will still be obstructed by the valve shaft and the sealing plug, affecting the flow of gas in the outer ring channel, and thus affecting the gas flow rate of the outer ring fire, resulting in insufficient firepower of the outer ring fire.

[0005] In addition, the solenoid valve for stir-frying is directly and vertically installed on the outer wall of the outer ring vent pipe, so that the gas valve is as shown in the attached diagram of its instruction manual. Figure 2 The increased lateral dimensions, and more importantly, the overall weight of the stir-fry solenoid valve, make it difficult to install and connect using only the outer wall of the outer ring vent pipe. This results in insufficient connection strength and makes the gas valve prone to load imbalance, leading to poor overall product quality. Utility Model Content

[0006] To at least partially solve the above-mentioned technical problems, this utility model proposes a novel stir-fry-based stopcock valve.

[0007] The present invention relates to a stir-fry-based stopcock valve, the specific technical solution of which is as follows: a stir-fry-based stopcock valve is provided, comprising a valve body, wherein the valve body is configured with an air inlet channel, an inner ring air outlet channel and an outer ring air outlet channel that are both connected to the air inlet channel, and a downwardly extending stir-fry air chamber is provided on the valve body between the inner ring air outlet channel and the outer ring air outlet channel. The stir-fry air chamber is configured with a stir-fry air passage, the inlet end of the stir-fry air passage is connected to the outer ring air outlet channel, and the outlet end of the stir-fry air passage is connected to the inner ring air outlet channel. A stir-fry solenoid valve is installed on the end of the stir-fry air chamber near the outer ring air outlet channel to control the opening and closing of the stir-fry air passage.

[0008] Preferably, the gas in the outer ring outlet channel forms a non-opening / closing flow.

[0009] Preferably, the valve body further comprises a valve cavity, the inner ring outlet pipe where the inner ring outlet channel is located is connected to the valve cavity seat where the valve cavity is located, and the outer ring outlet pipe where the outer ring outlet channel is located includes a first outlet pipe connected to the valve cavity seat and a second outlet pipe connected to the first outlet pipe. The second outlet pipe and the inner ring outlet pipe both extend on the same side in a direction opposite to the valve cavity seat.

[0010] Preferably, the stir-frying air chamber includes a top mounting part and a mounting base that is detachably connected to the top mounting part by fasteners. The top mounting part and the mounting base together form the stir-frying air passage, and the stir-frying solenoid valve is installed on the mounting base.

[0011] Preferably, the stir-frying air passage includes a stir-frying air inlet passage, a stir-frying air outlet passage, and a connecting passage connecting the stir-frying air inlet passage and the stir-frying air outlet passage. The inlet end of the stir-frying air inlet passage is connected to the outer ring air outlet passage, and the outlet end of the stir-frying air outlet passage is connected to the inner ring air outlet passage. The stir-frying solenoid valve is installed at the outer end of the connecting passage, and the valve shaft of the stir-frying solenoid valve extends into the connecting passage and seals against the inlet end of the stir-frying air outlet passage.

[0012] Preferably, the top mounting portion connects the valve chamber seat, the outer ring air outlet pipe, and the inner ring air outlet pipe, and extends in a direction opposite to that of the valve chamber seat.

[0013] Preferably, the stir-fry solenoid valve is installed after the stir-fry gas chamber and extends vertically outward below the second gas outlet pipe.

[0014] Preferably, the mounting base and the top mounting part are sealed together. The stir-fry air intake channel has an upper air intake channel extending in a direction opposite to that of the valve chamber seat and a lower air intake channel connected to the upper air intake channel. The upper air intake channel is formed by the sealed mounting base and the top mounting part. The upper air intake channel is connected to the first air outlet pipe. The lower air intake channel is connected to the lower connecting channel. The lower air intake channel and the connecting channel are constructed within the mounting base.

[0015] Preferably, the stir-frying exhaust channel has a lower exhaust channel connected to the junction channel and an upper exhaust channel connected to the lower exhaust channel. The upper exhaust channel is connected to the inner ring exhaust channel. The lower exhaust channel and the upper exhaust channel are constructed within the mounting base.

[0016] The plug valve of this invention is installed on the stir-frying gas chamber, rather than on the outer side of the outer ring gas outlet pipe where the outer ring gas outlet channel is located. Therefore, the gas will not be obstructed when it flows in the outer ring gas outlet channel, and the gas flow rate of the outer ring fire will not be affected, thus ensuring the firepower of the outer ring fire.

[0017] The plug valve of this invention has a stir-frying chamber located on the valve body between the inner and outer ring air outlet channels and extending downwards. This allows the stir-frying solenoid valve to be installed on the end of the stir-frying chamber near the outer ring air outlet channel. Compared with the prior art, the load bias of the plug valve for the stir-frying chamber and the stir-frying solenoid valve is as non-biased as possible. Furthermore, the stir-frying chamber is not solely located on the outer ring air outlet pipe where the outer ring air outlet channel is located. As a result, the overall connection strength is improved, and the overall quality of the plug valve is enhanced. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of specific embodiments of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the teachings of the following embodiments are within the protection scope of this utility model.

[0024] The plug valve based on stir-frying in this utility model includes a valve body, in which a valve cavity and various channels are constructed. A valve core is installed in the valve cavity. After the components are assembled, they together constitute the plug valve.

[0025] The following describes the specific embodiments in detail, such as... Figures 1-4As shown, in this embodiment, a stopcock valve based on stir-frying is provided, which includes a valve body 1. The valve body 1 is configured with an air inlet channel 2, an inner ring air outlet channel 3 and an outer ring air outlet channel 4, both of which are connected to the air inlet channel 2. A stir-frying air chamber 5 extending downward is also provided on the valve body 1 between the inner ring air outlet channel 3 and the outer ring air outlet channel 4. The stir-frying air chamber 5 is configured with a stir-frying air passage 6. The inlet end of the stir-frying air passage 6 is connected to the outer ring air outlet channel 4, and the outlet end of the stir-frying air passage 6 is connected to the inner ring air outlet channel 3. A stir-frying solenoid valve 7 is installed on the end of the stir-frying air chamber 5 near the outer ring air outlet channel 4 to control the opening and closing of the stir-frying air passage 6.

[0026] Specifically, in this embodiment, the valve body 1 further comprises a valve cavity (not shown) for mounting a valve core (not shown). The inner ring outlet pipe 31, where the inner ring outlet channel 3 is located, is substantially perpendicularly connected to the valve cavity seat 8 where the valve cavity is located. The outer ring outlet pipe 41, where the outer ring outlet channel 4 is located, includes a first outlet pipe 410, which is also substantially perpendicularly connected to the valve cavity seat 8, and a second outlet pipe 411, which is substantially perpendicularly connected to the first outlet pipe 410. The first outlet pipe 410 and the inner ring outlet pipe 31 are also substantially perpendicularly positioned. The second outlet pipe 411 and the inner ring outlet pipe 31 both extend on the same side in a direction opposite to the valve cavity seat 8. For more details, please refer to... Figure 2 The orientation shown can be understood as being located primarily in front of the first exhaust pipe 410. Thus, the stopcock valve of this structure, through the aforementioned outer ring exhaust pipe 41, valve seat 8, and inner ring exhaust pipe 31, forms an open U-shaped space. The stir-fry chamber 5 is essentially located within this U-shaped space and extends downwards from it. This spatial arrangement avoids load bias in the stopcock valve and fully utilizes the U-shaped space, allowing the stir-fry chamber 5 to connect marginally with the adjacent outer ring exhaust pipe 41, valve seat 8, and inner ring exhaust pipe 31 to increase the connection strength between components and improve product quality.

[0027] Through the above-described structure and design, the plug valve allows gas from the outer ring outlet channel 4 to partially flow into the inner ring outlet channel 3 when stir-frying is required, by opening the stir-frying solenoid valve 7, thereby increasing the gas flow rate of the inner ring outlet channel 3 and creating an inner ring stir-frying effect.

[0028] The above-described plug valve, because the solenoid valve 7 is not directly installed on the side of the outer ring outlet pipe 41 where the outer ring outlet channel 4 is located, but is installed on the end of the stir-frying air chamber 5 near the outer ring outlet channel 4, and the stir-frying air chamber 5 is located on the valve body 1 between the inner ring outlet channel 3 and the outer ring outlet channel 4 and extends downward, on the one hand, avoids the solenoid valve 7 being directly installed on the outer ring outlet pipe 41 and affecting the flow of gas in the outer ring outlet channel 4, and on the other hand, ensures that the load on the plug valve is not directly set as an off-center load, which not only enhances the connection strength, but also improves the overall quality of the product.

[0029] It should be noted that in the stopcock valve of this invention, the gas in the outer annular outlet channel 4 forms a non-opening / closing flow. This non-opening / closing flow means that no valve body is provided for opening or closing the gas flow. Therefore, for the stopcock valve of this invention, gas flows through the outer annular outlet channel 4 regardless of whether stir-frying is required or the stir-frying gas passage 6 is closed.

[0030] As an important functional component of the plug valve of this utility model, the stir-frying air chamber 5 is constructed in the following manner. Specifically, the stir-frying air chamber 5 includes a top mounting part 51 and a mounting base 52 detachably connected to the top mounting part 51 by fasteners. The top mounting part 51 and the mounting base 52 together form the stir-frying air passage 6, and the stir-frying solenoid valve 7 is mounted on the mounting base 52. In this way, when processing and forming the valve body 1, the mounting base 52 can be formed separately, while the top mounting part 51 can be integrally formed during the forming of the valve body 1.

[0031] It should be noted that, to enhance the connection strength, in this embodiment, the inner side of the top mounting portion 51 is directly connected to the sidewalls of the valve seat 8, the outer ring air outlet pipe 41, and the inner ring air outlet pipe 31. Furthermore, the top mounting portion 51 extends horizontally outward in a direction opposite to the valve seat 8, and is positioned at approximately the same height as, or slightly above or below, the inner ring air outlet pipe 31. Thus, the top mounting portion 51 allows it to be connected to the valve seat 8, the outer ring air outlet pipe 41, and the inner ring air outlet pipe 31 into a single integrated structure, thereby increasing the connection strength.

[0032] As the core structure of the stir-frying air chamber 5, the stir-frying air passage 6 in this embodiment mainly includes a stir-frying air inlet passage 61, a stir-frying air outlet passage 62, and a connecting passage 63 connecting the stir-frying air inlet passage 61 and the stir-frying air outlet passage 62. The inlet end of the stir-frying air inlet passage 61 is vertically connected to the outer ring air outlet passage 4, and the outlet end of the stir-frying air outlet passage 62 is vertically connected to the inner ring air outlet passage 3. The stir-frying solenoid valve 7 is installed at the outer end of the connecting passage 63, and the valve shaft 71 of the stir-frying solenoid valve 7 extends into the connecting passage 63 and seals and presses against the inlet end of the stir-frying air outlet passage 62. As can be seen, the stir-fry air passage 6 is formed by the sequential arrangement of the stir-fry air intake channel 61, the connecting channel 63, and the stir-fry air outlet channel 62. This allows the gas from the outer ring air outlet channel 4 to flow into the inner ring air outlet channel 3 through the stir-fry air intake channel 61. During the inflow, the stir-fry solenoid valve 7 can open and close the flowing gas. More importantly, the stir-fry solenoid valve 7 can be fitted to the outer end of the connecting channel 63. The outer end of the connecting channel 63 is relatively closer to the inner ring air outlet pipe 31 than the outer side of the outer ring air outlet pipe 41. This effectively reduces the length of the stir-fry solenoid valve 7 extending outward relative to the outer ring air outlet pipe 41, thereby reducing the length of the stopcock valve extending outward in this direction and making the structure more compact.

[0033] Furthermore, the top mounting portion 51 is essentially a plate-like structure, and is integrated with the nearby valve seat 8, outer ring vent pipe 41, and inner ring vent pipe 31. It also has a flat mounting bottom surface (not marked). The mounting base 52 has a mounting top 520 that attaches to the top mounting portion 51, and the mounting top 520 has a flat mounting top surface (not marked). After attachment, the two are detachably connected using fasteners. During attachment, sealing gaskets are provided at each channel to form a sealed attachment.

[0034] The stir-fry air intake channel 61 includes an upper air intake channel 610 extending in a direction opposite to the valve chamber seat 8 and a lower air intake channel 611 perpendicularly connected to the upper air intake channel 610. The upper air intake channel 610 is formed by the mounting top 520 and the top mounting part 51. The upper air intake channel 610 is perpendicularly connected to the first air outlet pipe 410, and the lower air intake channel 611 is also perpendicularly connected to the lower connecting channel 63. The lower air intake channel 611 and the connecting channel 63 are constructed within the mounting base 52.

[0035] Meanwhile, the stir-frying venting channel 62 has a lower venting channel 620 coaxially connected to the confluence channel 63 and an upper venting channel 621 perpendicularly connected to the lower venting channel 620. The upper venting channel 621 is perpendicularly connected to the inner ring venting channel 3. The lower venting channel 620 and the upper venting channel 621 are constructed within the mounting base 52.

[0036] For each channel, it is preferable to open it using a circular hole channel.

[0037] It should be noted that the mounting base 52 is also provided with a mounting end 521, which is located at the outer end of the connecting channel 63 for mounting the stir-fry solenoid valve 7. Meanwhile, the body of the mounting base 52 forms two outwardly protruding structures of different sizes. After being installed in the stir-fry gas chamber, the stir-fry solenoid valve 7 extends vertically outward below the second gas outlet pipe 411.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
