The top of the outer lug 130 is provided with a threaded hole 140, the inner wall of the flow guide transverse groove 160 is provided with a through hole 150 communicated with the threaded hole 140, the other side of the flow guide transverse groove 160 is provided with a mounting groove hole 190 opposite to the through hole 150, the first pressure sensor 210 and the second pressure sensor 220 are provided with an upper thread section 230 matched with the threaded hole 140 in a threaded manner, and the second pressure sensor 220 and the outer ring of the tail end of the first pressure sensor 210 are provided with a lower thread section 240. The automatic shutoff assembly 40 includes a segment housing 410, a block 430, a shutoff block 440, and a spring 450. The spring 450 is installed inside the mounting groove hole 190, the seat block 430 is arranged at the top of the spring 450, the seat block 430 and the spring 450 can be fixed through welding, a plugging block 440 in plug connection with the through hole 150 is arranged on one side, away from the spring 450, of the seat block 430, and the plugging block 440 is made of rubber with good sealing performance. The top end of the segment shell 410 is in screw-fit installation with the lower thread segment 240, and the side of the segment shell 410 is provided with a through hole 420.
The ball valve internal leakage detection device based on the pressure sensor has the working principle that oil in a pipeline enters through a liquid inlet end pipe 110 at one end of a ball valve main body 10 and is discharged from a liquid outlet end pipe 120 at the other end of the ball valve main body 10. The first pressure sensor 210 is used for monitoring the oil pressure at the oil inlet end pipe 110 in the ball valve body 10, and the second pressure sensor 220 is used for monitoring the oil pressure at the oil outlet end pipe 120 in the ball valve body 10. Specifically, the high-pressure oil in the liquid inlet end pipe 110 is the same as the oil pressure in the flow guiding transverse groove 160 communicated with the liquid inlet groove 170 and the liquid outlet groove 180, namely, the oil pressure in the flow guiding transverse groove 160 is monitored by the first pressure sensor 210 to be the oil pressure in the liquid inlet end pipe 110, and the oil pressure in the flow guiding transverse groove 160 in the corresponding outer bump 130 is monitored by the second pressure sensor 220 to be the oil pressure in the liquid outlet end pipe 120, namely, the oil pressure in the two ends of the ball valve main body 10 is monitored in real time. When the oil pressure inside the oil inlet pipe 110 is reduced, the internal leakage of the ball valve body 10 is generated.
When the first pressure sensor 210 and the second pressure sensor 220 need to be replaced, the first pressure sensor 210 and the second pressure sensor 220 are directly screwed out through the cooperation of the threaded hole 140 and the upper thread section 230. The exterior of the upper thread segments 230 may be provided with corresponding sealing structures. When the first and second pressure sensors 210 and 220 are rotated out of the screw holes 140, the segment cases 410 at the ends of the first and second pressure sensors 210 and 220 are moved together to be taken out. The gradually outwardly moving segment shells 410 relieve the pressure on the occlusion block 440 and the contracting spring 450 transitions to the relaxed state. The spring 450 expands the blocking block 440 of the end of the jack-up block 430 to the outside until entering the through hole 150, and the blocking is completed by the blocking block 440 entering the inside of the through hole 150, so that the oil inside the pipeline is prevented from leaking outwards through the through hole 150 and the threaded hole 140 when the first pressure sensor 210 and the second pressure sensor 220 are disassembled. The section shells 410 at the end parts of the first pressure sensor 210 and the second pressure sensor 220 are disassembled, the disassembled section shells 410 are installed at the end parts of the brand new first pressure sensor 210 and the second pressure sensor 220, namely, the section shells 410 are matched and butted through the lower thread section 240, and then the first pressure sensor 210 and the second pressure sensor 220 and the section shells 410 installed at the bottom are inserted into the threaded holes 140. When new first pressure sensor 210 and second pressure sensor 220 are installed, the bottom end of segment shell 410 contacts with plugging block 440 inside through hole 150 until segment shell 410 is inserted into diversion transverse groove 160 after first pressure sensor 210 and second pressure sensor 220 are completely screwed with threaded hole 140. The whole process can completely realize the rapid and convenient replacement of the first pressure sensor 210 and the second pressure sensor 220 even in the running process of the ball valve body 10.

The ball valve internal leakage detection device based on the pressure sensor can control information acquisition and transportation of the first pressure sensor 210 and the second pressure sensor 220 through matching with the control module 330, the control module 330 adopts a conventional control chip assembly which can be known by a person skilled in the art, and the connection mode between the control module 330 and the first pressure sensor 210 and the second pressure sensor 220 through the lead 340 is also a conventional technical means which can be known by a person skilled in the art, so that the detailed description is omitted. The first pressure sensor 210 and the second pressure sensor 220 are both fast plugged with the control module 330 through the matching of the lead 340 and the connector 350, so that the replacement of the first pressure sensor 210 and the second pressure sensor 220 is more convenient.

Specifically, an expansion port 181 is disposed at the bottom end of the liquid outlet slot 180. The arrangement of the expansion port 181 prevents impurities from blocking the tail end of the liquid outlet slot 180. The side of the seat block 430 is provided with a guide bar 460, the inner wall of the mounting slot 190 is provided with a guide groove 191 which is matched with the guide bar 460 in a sliding way, and the arrangement of the guide bar 460 and the guide groove 191 is used for improving the stability of the seat block 430 when moving inside the mounting slot 190. The through hole 150 has an inner diameter smaller than the threaded hole 140, and the segment case 410 has a diameter smaller than the inner diameter of the through hole 150.
In the long-time use process of the ball valve internal leakage detection device based on the pressure sensor, since the liquid in the communication cavity formed by the liquid inlet groove hole 170, the flow guide transverse groove 160 and the liquid outlet groove hole 180 is in a static state for a long time, even if the ball valve main body 10 is opened, the liquid circulation is very slow, and the situation that the liquid inlet groove hole 170 and the liquid outlet groove hole 180 are blocked by impurities easily occurs.
Referring to fig. 3, 8, 9 and 10, the ball valve internal leakage detecting device based on a pressure sensor further includes a flow guiding self-cleaning assembly 50, and two sets of flow guiding self-cleaning assemblies 50 are respectively installed on front sides of the liquid inlet slots 170 on inner walls of the liquid inlet end pipe 110 and the liquid outlet end pipe 120. The deflector self-cleaning assembly 50 includes a deflector block 510, a screen separating plate 520, and a shaft 530. The front side of the flow guiding block 510 is provided with a front flow guiding groove 580, the back of the flow guiding block 510 is provided with a rear flow guiding groove 560 communicated with the front flow guiding groove 580, the inner diameter of the rear flow guiding groove 560 is gradually reduced from the front flow guiding groove 580 to the rear, and the front end of the front flow guiding groove 580 is provided with diffusion. The shaft 530 is fixed at one side of the screen division plate 520, and a shaft hole 570 in rotation fit with the shaft 530 is provided in the rear diversion trench 560. The split screen plate 520 is rotatably clamped in the rear diversion trench 560, the end part of the split screen plate 520 is provided with a limit convex part 550, and the side surface of the split screen plate 520 is provided with a plurality of water filtering holes 540 inclined to the end part of the liquid inlet slot 170.
The purpose of arranging the diversion self-cleaning assembly 50 on the inner walls of the liquid inlet end pipe 110 and the liquid outlet end pipe 120 is that when the ball valve main body 10 is opened, when the oil circulates through the liquid inlet end pipe 110 and the liquid outlet end pipe 120, part of the circulated oil flows into the rear diversion trench 560 to be contacted with the partial sieve plate 520 through the front diversion trench 580 on the front side of the diversion block 510. Part of the fluid is collected in the rear diversion trench 560 at the rear side after passing through the water filtering holes 540 at the side surface of the sieve plate 520, and is impacted to the bottom end of the liquid inlet slot 170 in an inclined way. That is, the larger impurities in the fluid are blocked by the separating screen plate 520 from being obliquely guided away from the positions of the liquid outlet slot 180 and the mounting slot 190, so that the possibility that the larger impurities block the bottoms of the liquid outlet slot 180 and the mounting slot 190 is reduced. Fluid filtered through the side water filtering holes 540 of the split screen plate 520 obliquely impacts the bottom of the liquid inlet slot hole 170, clean fluid after filtration rapidly enters the guide transverse slot 160 from the bottom of the liquid inlet slot hole 170 and finally is discharged from the liquid outlet slot hole 180, and the fluid which rapidly circulates can bring out impurities remained in the liquid inlet slot hole 170, the guide transverse slot 160 and the liquid outlet slot hole 180 during the closing of the ball valve main body 10, so that the automatic cleaning function is achieved, and the accuracy of the monitoring of the first pressure sensor 210 and the second pressure sensor 220 is prevented from being influenced due to the blocking of the liquid inlet slot hole 170 and the liquid outlet slot hole 180.
Because the front diversion trench 580 is open, the fluid can enter the front diversion trench 580 more, and then pass through the back diversion trench 560 with gradually reduced size, i.e. the velocity of the fluid will increase, and the fluid will quickly impact and penetrate the filtering water hole 540, and then be converged at the tail end of the back diversion trench 560 to impact to the bottom of the liquid inlet slot 170. The design of the front diversion trench 580 expanding opening is to collect more flow of liquid, the design of the rear diversion trench 560 gradually becoming smaller is to increase the flow velocity of the fluid, so that the fluid entering the bottom end of the liquid inlet slot 170 has a faster speed to clean the impurities inside the liquid inlet slot 170, the diversion transverse slot 160 and the liquid outlet slot 180, and the impurity cleaning quality is improved.
The rotation setting of axostylus axostyle 530 and shaft hole 570 on one side of minute sieve 520, when ball valve main part 10 is opened, the fluid that flows will strike minute sieve 520 fast, and minute sieve 520 and the contact of guide block 510 inner wall back, minute sieve 520 stop the removal immediately, and the inertia that produces when stopping in the twinkling of an eye will make minute sieve 520 original surface and the impurity vibrations that water drainage hole 540 surface attached are cleared up, guarantee that the fluid can pass from water drainage hole 540 better.
In the above ball valve internal leakage detection device based on the pressure sensor, the fluid guided by the front guide groove 580 and the rear guide groove 560 in the guide block 510 can impact the bottom of the liquid inlet groove 170 with a strong impact force into the liquid inlet groove 170, and when the moving fluid enters the rear section of the channel formed by the liquid inlet groove 170, the guide transverse groove 160 and the liquid outlet groove 180, the fluid impact cleaning effect is reduced.
Referring to fig. 4, 7, 11 and 12, the ball valve internal leakage detecting device based on a pressure sensor further includes a turbulence blocking prevention assembly 60, wherein the turbulence blocking prevention assembly 60 includes a fixing rod 610, a rotating shaft 620, a helical blade 630, a hollow truncated cone-shaped diversion sleeve 640 and a blade 650. The bottom of the fixed rod 610 is fixedly connected with the bottom wall of the through hole 420 inside the section shell 410, one end of the rotating shaft 620 is rotationally connected with the top end of the fixed rod 610, the spiral blades 630 are fixedly sleeved outside the rotating shaft 620, the outer diameters of the blades of the spiral blades 630 are gradually reduced, the diversion sleeve shell 640 is fixedly sleeved outside the spiral blades 630, the plurality of groups of blades 650 are arranged outside the diversion sleeve 640 in an annular array, and the two sides of the outer edge of the front end of the diversion sleeve 640 are provided with concave areas 660.
The fluid guided from the front guide groove 580 and the rear guide groove 560 obliquely impacts to the bottom of the liquid inlet slot 170, and part of the fluid rapidly flows into the guide transverse groove 160 through the liquid inlet slot 170. Fluid entering the interior of the transverse baffle slot 160 enters from the large diameter end of the baffle housing 640. And then exits through the small ports of the baffle housing 640. During the fluid entering the sleeves 640 and exiting, the fluid impinges on the surfaces of the helical blades 630, causing the helical blades 630 and sleeves 640 to rotate about the central axis of rotation 620. The rotating diversion sleeve shell 640 also drives the external blade 650 to rotate, the helical blades 630 with gradually reduced caliber and the diversion sleeve shell 640 are arranged, when fluid is discharged from the tail end of the diversion sleeve shell 640, the faster circulation speed is achieved, and the blade 650 and the helical blades 630 are arranged to increase the turbulence effect on the fluid, so that the fluid passing through the turbulence anti-blocking assembly 60 can be accelerated and disturbed, impurities remained in the diversion transverse groove 160 and the liquid outlet slot 180 at the rear section of the turbulence anti-blocking assembly 60 are cleaned more easily, and the cleaning effect of the fluid on the rear section of the diversion transverse groove 160 and the inside of the liquid outlet slot 180 is further improved.
The recessed area 660 of the broken diversion jacket 640 is arranged so that the diversion jacket 640 is as much as possible, and the inside of the through hole 420 of the section shell 410 is not affected by the installation of the turbulence blocking prevention component 60, so that the turbulence blocking prevention component 60 is conveniently installed inside the through hole 420, and is inserted into the through hole 150 together with the section shell 410 to be installed inside the diversion transverse groove 160.
