Description

Technical Field

[0001] The present invention belongs to the technical field of ball valves, and particularly relates to a natural gas ball valve capable of monitoring natural gas concentration. Background Art

[0002] During the use of natural gas ball valves, wear inevitably occurs. When the wear reaches a certain level, it will cause slight natural gas leakage. When the leakage level is low, it is difficult for users to detect. If waiting until the natural gas leakage can be detected by users and then notifying the maintenance personnel for repair, there will be certain potential safety hazards.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", "around", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0033] Please refer to Figures 1-9As shown in the figure, the present invention is a natural gas ball valve capable of monitoring the natural gas concentration, which includes a main body structure 100, a blocking structure 200, a connecting structure 300, a detection structure 400, a fixing structure 500, a mounting structure 600, and a ventilation structure 700. The main body structure 100 includes a valve body 110 and a mounting cylinder 120. The mounting cylinder 120 is installed on the outer surface of the valve body 110. The blocking structure 200 includes a butt joint circular tube 210. One end of the butt joint circular tube 210 is connected to one end of the valve body 110. The connecting structure 300 includes a first branch pipe 310, a second branch pipe 320, and a lower ventilation pipe 330. One end of the first branch pipe 310 is connected to the other end of the valve body 110. One end of the second branch pipe 320 is connected to the other end of the butt joint circular tube 210. The detection structure 400 includes a first concentration detector 410, a second concentration detector 420, and an intake pipe 450. The first concentration detector 410 is installed on the outer surface of the first branch pipe 310. The second concentration detector 420 is installed on the outer surface of the second branch pipe 320. One end of the intake pipe 450 is connected to the lower surface of the second concentration detector 420. The fixing structure 500 includes a first fixing block 510 and a second fixing block 520. One end of the first fixing block 510 is connected to the outer surface of the first branch pipe 310. One end of the second fixing block 520 is connected to the outer surface of the valve body 110. The mounting structure 600 includes a restraining ring cylinder 610. A plurality of restraining ring cylinders 610 are all installed on the outer surface of the lower ventilation pipe 330. The ventilation structure 700 includes a shaft cylinder 710 and a push rod 720. There is a mounting hole on the outer surface of the second branch pipe 320. The shaft cylinder 710 is connected to the mounting hole. The push rod 720 is arranged on the inner surface of the shaft cylinder 710. The push rod 720 is slidably matched with the shaft cylinder 710.

[0034] In order to facilitate the control of the flow rate of natural gas in the pipeline, the main body structure 100 further includes a valve rod 130, a rotating handle 140, and a valve ball 150. The valve rod 130 is arranged inside the mounting cylinder 120. The valve rod 130 is rotationally matched with the mounting cylinder 120. The rotating handle 140 is installed on the outer surface of one end of the valve rod 130. The valve ball 150 is arranged inside the valve body 110. The outer surface of the valve ball 150 is connected to the other end of the valve rod 130. Among them, the rotating handle 140 plays the role of rotating the valve rod 130, and then rotates the valve ball 150 to open and close. The operator can rotate the rotating handle 140 to drive the valve rod 130 to rotate. There is a valve ball 150 below the valve rod 130. Then, by rotating and adjusting the angular orientation of the valve ball 150, the cross-sectional area of natural gas flow is adjusted, and then the flow rate of natural gas is adjusted.

[0035] To facilitate the replacement and maintenance of the ball valve structure, the blocking structure 200 further includes a blocking valve 220, which is installed on the outer surface of the butt joint circular pipe 210. Among them, the blocking valve 220 serves to block the ventilation of the butt joint circular pipe 210. When it is known that the ball valve structure leaks, the operator can rotate the blocking valve 220, thereby changing the flow direction of the natural gas and closing the internal gas flow of the butt joint circular pipe 210, which facilitates the disassembly of the ball valve components.

[0036] To facilitate the continuous flow of natural gas during the maintenance of the ball valve structure, the connecting structure 300 further includes a switch valve disc 340, which is installed on the outer surface of the lower ventilation pipe 330. Among them, the switch valve disc 340 serves to control the ventilation of the lower ventilation pipe 330. The operator can rotate the blocking valve 220 and open the switch valve disc 340 to change the passage of the natural gas, so that it can flow through the lower ventilation pipe 330, which facilitates the continuous supply of gas inside the natural gas pipeline during the maintenance of the ball valve structure, and the structural design is user-friendly.

[0037] To facilitate the timely determination of the specific location of the natural gas leak, the detection structure 400 further includes a first pointer disk 430 and a second pointer disk 440. The lower surface of the first pointer disk 430 is connected to the upper surface of the first concentration detector 410, and the lower surface of the second pointer disk 440 is connected to the upper surface of the second concentration detector 420. Among them, both the first pointer disk 430 and the second pointer disk 440 serve to display the gas concentration value. By using the first concentration detector 410 to detect the natural gas concentration, when the concentration value of the first pointer disk 430 fluctuates, it is known that the pipeline or the ball valve structure leaks. To further know the specific leaking component, the natural gas inside the pipeline enters the second concentration detector 420 through the intake pipe 450 through the ventilation structure 700 for concentration detection. When there is a difference between the readings of the second pointer disk 440 and the first pointer disk 430, it can be known that the ball valve structure leaks.

[0038] To facilitate the installation and disassembly of the ball valve structure, the fixing structure 500 further includes an internal thread cylinder 530 and a bolt rod 540. A first through hole is provided on one side surface of the first fixing block 510, and the internal thread cylinder 530 is connected to the first through hole. A second through hole is provided on one side surface of the second fixing block 520, and the bolt rod 540 is connected to the second through hole. The bolt rod 540 is rotationally matched with the internal thread cylinder 530. Among them, the rotational matching of the bolt rod 540 and the internal thread cylinder 530 serves to fix and connect. The maintenance personnel can rotate the bolt rod 540 to facilitate the disassembly of the valve body 110, which facilitates replacement and maintenance.

[0039] To facilitate the stable connection of the ball valve components, the mounting structure 600 further includes a support plate 620, a mounting plate 630, and fixing bolts 640. One side surface of the support plate 620 is connected to the outer surface of the restraint ring cylinder 610, one side surface of the mounting plate 630 is connected to one side surface of the support plate 620, and a number of reserved holes are provided on the upper surface of the mounting plate 630, and fixing bolts 640 are arranged inside the reserved holes. Among them, the support plate 620 is in contact with the ground, thus playing a supporting role. The installer contacts and presses the support plate 620 against the ground or the wall surface, and then uses the fixing bolts 640 for connection, thereby enhancing the overall stability of the device.

[0040] To further detect whether the ball valve components are leaking, the ventilation structure 700 further includes strengthening rods 730, springs 740, handle rods 750, and sealing disks 760. A number of strengthening rods 730 are all installed on the outer surface of the second branch pipe 320. One end of each of the number of strengthening rods 730 is connected to the outer surface of the shaft cylinder 710. One end of the handle rod 750 is connected to one end of the ejector rod 720. One side surface of the sealing disk 760 is connected to the other end of the ejector rod 720. The spring 740 is installed on the outer surface of the ejector rod 720. Among them, the sealing disk 760 is arranged at one end of the intake pipe 450, thus facilitating the blocking and sealing of the intake pipe 450 and opening the intake. The operator can, by utilizing the sliding fit characteristic of the ejector rod 720 and the shaft cylinder 710 and the compression characteristic of the spring 740, then move the ejector rod 720 outward, thereby separating the sealing disk 760 from the intake pipe 450. At this time, natural gas enters the second concentration detector 420 through the intake pipe 450 for concentration detection, and observes whether there is a difference in the readings for judgment.
