Description

Technical Field

[0001] This application relates to the field of cock positioning technology, and in particular to a cock installation and positioning device for coke oven gas exchange. Background Technology

[0002] Cocktail valves belong to the field of actuated valve technology and are widely used in oil extraction, chemical production and gas transmission. For example, in the coke oven production process, the stable operation of the underground coke oven gas heating system is crucial. Uniform heating of the coke oven relies on the reversing system, and the working state of the cocktail valve, as the main device for controlling the gas reversing, directly affects the safety of the underground coke oven gas heating system. In the periodic airflow exchange of the underground coke oven gas heating system, air must be introduced first and then gas is introduced in order to avoid residual gas causing an explosion.

[0003] However, a traditional stopcock includes a stopcock housing 101, a stopcock core 102, a handle, a spring, and a fixing bolt. The stopcock housing has a gas inlet 1011, a flue gas inlet 1012, and an air inlet 1013. The stopcock core 102 has a gas supply through-hole 1021 connecting the air inlet 1013 and the flue gas inlet 1012, or connecting the gas inlet 1011 and the flue gas inlet 1012. To facilitate the reversal of gas flow by rotating the stopcock core 102 within the stopcock housing 101, an operating post 500 is typically provided on the end face of the stopcock core 102 located outside the stopcock housing 101. The handle has an operating groove 600 that can act on the operating post 500 in any direction. Specifically, in the initial state, after the stopcock core 102 is inserted into the stopcock housing 101, it is in a... Figure 1 In state (a) (air is introduced first), the valve core 102 is rotated within the valve housing 101 by using a wrench to rotate the valve core 102 to the desired position. Figure 1 In state (b) (gas is introduced), air and gas eventually mix. Because the cock core 102 is directional, while the operating column 500 and operating groove 600 can be matched in any direction, there may be issues after the operator installs the disassembled cock core 102 into the cock housing 101. Figure 2 The conditions shown in (c) and (d) (gas may leak into the air and an explosion may occur when gas and air enter the flue simultaneously) and Figure 2 The state shown in (e) (where gas entering the vertical flue disrupts the normal heating process and even poses a risk of explosion) is... Figure 2 The situation described could lead to serious safety accidents such as poisoning of people in the basement, gas fires, or even explosions, posing a significant risk to production. Therefore, this application proposes a cocking and positioning device for coke oven gas exchange. Utility Model Content

[0004] This application provides a cock installation and positioning device for coke oven gas exchange, which solves the technical problems described in the background art above.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0008] An exchange wrench is provided with a mounting hole and a positioning hole, which correspond to the mounting shaft and the positioning shaft, respectively. The exchange wrench is used to drive the rotary valve core to rotate within the rotary valve housing through the mounting hole and the positioning hole, respectively, so as to adjust the heating process of the coke oven.

[0009] When the valve core is installed, the exchange wrench is always in the first working state.

[0013] The third positioning axis is used to indicate the air inlet;

[0014] There are three positioning holes, and each of the three positioning holes corresponds to the first positioning shaft, the second positioning shaft, and the third positioning shaft.

[0016] Optionally, the mounting shaft is provided with a first mounting hole corresponding to the first positioning shaft, a second mounting hole corresponding to the second positioning shaft, and a third mounting hole corresponding to the third positioning shaft;

[0017] The first positioning shaft is threadedly connected to the first mounting hole, the second positioning shaft is threadedly connected to the second mounting hole, and the third positioning shaft is threadedly connected to the third mounting hole;

[0018] The first positioning shaft, the second positioning shaft, and the third positioning shaft are respectively provided with a first replacement hole, a second replacement hole, and a third replacement hole along their own length direction.

[0019] Optionally, the mounting shaft includes an integrally formed first mounting shaft segment and a second mounting shaft segment;

An installation hole and a positioning hole, corresponding to the installation shaft and positioning shaft respectively, are provided on the exchange wrench. Each time the plug core is installed, the exchange wrench is always in its first working state.

Compared with the prior art, this application improves the accuracy of plug core installation and positioning, thereby ensuring the safety of the underground coke oven gas heating system.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0037] refer to Figures 1 to 8 This application provides a cock installation and positioning device for coke oven gas exchange, comprising:

[0038] The cock body 100 includes a cock housing 101 and a cock core 102 rotatably disposed within the cock housing 101. A mounting shaft 200 is provided on the end face of the cock core 102 located outside the cock housing 101, and a positioning shaft 300 is provided on the outer peripheral wall of the mounting shaft 200. In addition to the cock housing 101 and the cock core 102, the cock body 100 also includes components such as a handle, spring, and fixing bolts as described in the prior art, which are existing technologies and will not be described in detail here.

[0039] An exchange wrench 400 has a mounting hole 401 and a positioning hole 402, which correspond to the mounting shaft 200 and the positioning shaft 300, respectively. The exchange wrench 400 is used to rotate the cock core 102 within the cock housing 101 through the mounting hole 401 and the positioning hole 402, respectively, to adjust the heating process of the coke oven. Because the exchange wrench 400 rotates through the mounting hole 401 and the positioning hole 402, it can also adjust the heating process of the coke oven. The hole 402 cooperates with the mounting shaft 200 and positioning shaft 300 on the plug core 102, so that if the position of the change wrench 400 is determined, even if the mounting shaft 200 on the plug core 102 is in any direction when it is installed inside the plug housing 101, it can still correspond to the mounting hole 401 on the change wrench 400. However, since the positioning hole 102 must be aligned with the positioning shaft 300, the installation position of the plug core 102 is unique, thus improving the accuracy of the installation of the plug core 102.

[0040] When installing the rotary valve core 102, the exchange wrench 400 is always in the first working state. The first working state corresponds to... Figure 1 The state shown in (a) is when the valve core 102 is inserted into the valve housing 101, and air is first introduced. In addition, there is a second operating state, which corresponds to... Figure 1 The working state shown in (b) is that the gas is being supplied.

[0041] The coke oven gas exchange plug installation and positioning device provided in this application has an installation shaft 200 provided on the end face of the plug core 102 located outside the plug housing 101, and a positioning shaft 300 provided on the outer peripheral wall of the installation shaft 200. An installation hole 401 and a positioning hole 402 corresponding to the installation shaft 200 and positioning shaft 300, respectively, are provided on the exchange wrench 400. Each time the plug core 102 is installed, the exchange wrench 400 is always in the first working state; that is, even if the installation hole 401 and the installation shaft 200 are in any position... In the case of matching, in order to install the plug core 102 into the plug housing 101, the positioning shaft 300 on the plug core 102 needs to correspond to the positioning hole 402 on the exchange wrench 400 when it is in the first working state. This makes the installation direction of the positioning shaft 300 on the plug core 102 and the positioning hole 402 on the exchange wrench 400 unique, thereby avoiding the situation of incorrect installation of the plug core 102. Compared with the prior art, this application improves the accuracy of the installation and positioning of the plug core 102, thereby ensuring the safety of the basement coke oven gas heating system.

[0042] In some embodiments, reference Figure 3 The positioning shaft 300 in this application includes a first positioning shaft 301, a second positioning shaft 302, and a third positioning shaft 303. Specifically, the first positioning shaft 301 is used to indicate the gas inlet 1011; the second positioning shaft 302 is used to indicate the vertical flue inlet 1012; and the third positioning shaft 303 is used to indicate the air inlet 1013. There are three positioning holes 402, and the three positioning holes 402 correspond one-to-one with the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303, respectively.

[0043] In the above embodiments, since the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 are respectively used to indicate the gas inlet 1011, the vertical flue inlet 1012, and the air inlet 1013, each time before installing the valve core 102 into the valve housing 101, the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 can be respectively installed into the valve housing 101 corresponding to the gas inlet 1011, the vertical flue inlet 1012, and the air inlet 1013, thereby achieving one-time accurate installation of the valve core 102. In other words, the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 serve as prompts for the operator, greatly improving the efficiency of valve core 102 positioning and the accuracy of installation.

[0044] In some embodiments, reference Figure 5In this application, the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 are all L-shaped, and their diameters increase or decrease sequentially. This makes it easy for workers to quickly identify the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303, so as to quickly align the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 on the valve core 102 with the gas inlet 1011, the vertical flue inlet 1012, and the air inlet 1013 on the valve housing 101, respectively. This allows the valve core 102 to be quickly installed into the valve housing 101, saving installation time and improving the installation efficiency of the valve core 102.

[0045] In some embodiments, reference Figure 5 , Figure 7 and Figure 8 The mounting shaft 200 in this application has a first mounting hole 201 corresponding to the first positioning shaft 301, a second mounting hole 202 corresponding to the second positioning shaft 302, and a third mounting hole 203 corresponding to the third positioning shaft 303. Specifically, the first positioning shaft 301 is threaded to the first mounting hole 201, the second positioning shaft 302 is threaded to the second mounting hole 202, and the third positioning shaft 303 is threaded to the third mounting hole 203. After the exchange wrench 400 applies force to the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 for an extended period, the first... The first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 may be at risk of breaking when subjected to the tightening force from the change wrench 400. The arrangement of the first mounting hole 201, the second mounting hole 202, and the third mounting hole 203 facilitates the removal and replacement of the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 from their respective first mounting holes 201, the second mounting hole 202, and the third mounting hole 203, respectively, in the event of breakage. In addition, the threaded connection between the first positioning shaft 301 and the first mounting hole 201, the second positioning shaft 302 and the second mounting hole 202, and the third positioning shaft 303 and the third mounting hole 203 makes the connection between the first positioning shaft 301 and the first mounting hole 201, the second positioning shaft 302 and the second mounting hole 202, and the third positioning shaft 303 and the third mounting hole 203 more stable, thereby improving the stability of the first positioning shaft 301, the second positioning shaft 302 and the third positioning shaft 303 during the process of the change wrench 400 acting on the first positioning shaft 301, the second positioning shaft 302 and the third positioning shaft 303 and turning them.

[0046] The first positioning shaft 301, the second positioning shaft 302 and the third positioning shaft 303 are respectively provided with a first replacement hole 3011, a second replacement hole 3021 and a third replacement hole 3031 along their own length direction. Since the first positioning shaft 301, the second positioning shaft 302, and the third positioning shaft 303 may be at risk of breaking under the tightening force applied by the wrench after the changer 400 has been applied for a period of time, the first replacement hole 3011, the second replacement hole 3021, and the third replacement hole 303 may be exposed after the first positioning shaft 301, the second replacement hole 3021, and the third replacement hole 3031 are broken. The first replacement hole 3011, the second replacement hole 3021, and the third replacement hole 3031 can be replaced by applying external force (which may be an external support rod that matches the first replacement hole 3011, the second replacement hole 3021, and the third replacement hole 3031 respectively). This improves the replacement efficiency of the first replacement hole 3011, the second replacement hole 3021, and the third replacement hole 3031.

[0047] In some embodiments, reference Figure 3 and Figures 5 to 8 The mounting shaft 200 in this application includes an integrally formed first mounting shaft section 204 and a second mounting shaft section 205. Specifically, a fourth mounting hole 1022 corresponding to the first mounting shaft section 204 is provided on the end face of the valve core 102 located outside the valve housing 101. The first mounting shaft section 204 is threadedly connected to the fourth mounting hole 1022, and the second mounting shaft section 205 is adapted to the positioning hole 402. Since the mounting shaft 200 may be at risk of breakage under the tightening force applied by the change wrench 400 for a long time, the fourth mounting hole 1022 facilitates the removal and replacement of the mounting shaft 200 after breakage. Furthermore, the threaded connection between the mounting shaft 200 and the fourth mounting hole 1022 makes the connection between the two more stable.

[0048] Both the first mounting shaft segment 204 and the second mounting shaft segment 205 have two interconnected fourth replacement holes 2041 along the length of the mounting shaft 200. When the first mounting shaft segment 204 and the second mounting shaft segment 205 of the mounting shaft 200 break, the interconnected fourth replacement holes 2041 on the first mounting shaft segment 204 and the second mounting shaft segment 205 are exposed, facilitating the replacement of the mounting shaft 200 by applying external force (which could be an external support rod matching the fourth replacement hole 2041) to the fourth replacement hole 2041, thus improving the replacement efficiency of the mounting shaft 200.

[0049] In some embodiments, reference Figures 3 to 8 In this application, the second mounting shaft segment 205 is prism-shaped, and its two end faces along its length are polygons with a preset number of sides; specifically, the preset number of sides is an integer greater than or equal to 3. For example, when the preset number of sides is 3, the second mounting shaft segment 205 is triangular prism-shaped; when the preset number of sides is 4, the second mounting shaft segment 205 is quadrangular prism-shaped, and so on. This application does not further limit the specific value of the preset number of sides.

[0050] In the above embodiments, when the second mounting shaft segment 205 is prismatic, the mounting hole 401 on the exchange wrench 400 that matches the mounting shaft 200 is also prismatic. That is, the connection stability between the two is better because the mounting hole 401 on the exchange wrench 400 is adapted to the prismatic second mounting shaft segment 205. Compared with the circular second mounting shaft segment 205, the prismatic mounting shaft segment 200 makes it less likely for the exchange wrench 400 to slip during the turning process, and turns the plug core 102 to the required working state as quickly as possible, thereby improving the turning efficiency of the plug core 102.

[0051] In some embodiments, the mounting shaft 200 and the positioning shaft 300 in this application are both made of stainless steel.

[0052] In the above embodiments, since stainless steel has the characteristics of high strength, wear resistance and corrosion resistance, the mounting shaft 200 and positioning shaft 300 made of stainless steel have good performance, thereby extending the service life of the mounting shaft 200 and positioning shaft 300.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
