Specific implementation method one:

[0039] like Figure 1 and Figure 2 As shown, a new type of wear-resistant ball valve includes a movable frame 1, on which a valve body operation driver 2 and a load-sharing ball shell 3 are provided. The valve body operation driver 2 drives the dynamic retainer 4 to rotate in the load-sharing ball shell 3, and the upper limit sliding of the dynamic retainer 4 is provided with a pressure detection diverter 17 inserted in the load-sharing ball shell 3.

[0040] The working principle and beneficial effects of this embodiment are as follows: the entire device is moved by the mobile frame 1 to facilitate its use at different positions; the load-sharing spherical shell 3 on the mobile frame 1 is connected to the inlet main pipe at the use position, and the load-sharing spherical shell 3 is used to achieve the effect of diversion; the valve body operation driver 2 drives the dynamic retainer 4 to rotate in the load-sharing spherical shell 3, so that the dynamic retainer 4 and the pressure detection diverter 17 in the load-sharing spherical shell 3 perform continuous dynamic functions, and then when the added pressure of the added inlet main pipe is too high, the pressure detection diverter 17 moves downward in the load-sharing spherical shell 3. When the pressure is too high, a buffer space is reserved for the added flow, so that when the pressure alarm occurs at the first time, the liquid flow is buffered to avoid the danger of excessive pressure, and thus its working state can be quickly adjusted to ensure the safety of the entire pipeline; after the pressure decreases, the pressure detection diverter 17 is added to the load-sharing spherical shell 3 for continued diversion and real-time detection; at the same time, it can maintain stable performance during long-term operation and reduce the possibility of failure;

[0041] Continuously dynamic ball valves are suitable for various complex industrial environments and can cope with extreme conditions such as high temperature, high pressure, and corrosive media;

[0042] At the same time, the design focuses on easy maintenance, reducing downtime and improving the availability of the overall system;

[0043] It is generally widely used in industrial fields such as petroleum, chemical, natural gas, electric power, metallurgy, etc., especially in situations where frequent switching or flow adjustment is required. Specific implementation method two:

[0045] like Figure 1 — Figure 11 As shown, a new type of wear-resistant ball valve is provided, wherein a plurality of brake casters 5 are evenly fixed on the lower end of the movable frame 1 .

[0046] The working principle and beneficial effects of this embodiment are as follows: the use of multiple brake casters 5 facilitates the displacement of the entire device, and at the same time, through the provision of the brake casters 5, the device is effectively fixed after displacement to prevent deviation. Specific implementation method three:

[0049] The working principle and beneficial effects of this embodiment are: the valve body is driven by the transmission shaft of the driver 2 to rotate, the pulley 6 is connected by belt transmission, and the dynamic retainer 4 is driven by the transmission of the pulley 6 to rotate continuously in the load-sharing spherical shell 3. Specific implementation method four:

[0052] The working principle and beneficial effects of this embodiment are as follows: the pulley 6 operates the driver 2 through the valve body to enable the drive shaft 7 to drive the central sphere 9 to rotate continuously in the load-sharing spherical shell 3, thereby effectively and continuously maintaining real-time dynamic detection; the setting of the mechanical seal 8 effectively ensures the sealing effect of the rotation of the drive shaft 7 to prevent leakage during long-term rotation, and the mechanical seal 8 can be a product in the existing technology. Specific implementation method five:

[0055] The working principle and beneficial effects of this embodiment are as follows: a diverter spherical shell 13 is fixed between two spherical shell frames 12, thereby achieving the effect of fixing the diverter spherical shell 13, and a bearing seat 11 is fixed in the spherical shell frame 12, thereby facilitating the rotation of the drive shaft 7 connected to the bearing seat 11, and through the continuous rotation of the drive shaft 7, effective and continuous dynamic detection can be performed. Specific implementation method six:

[0057] like Figure 1 — Figure 11 As shown, a new wear-resistant ball valve, the upper end of the diverter ball shell 13 is connected and fixed with an inlet pipe 14, and the two sides of the lower end of the diverter ball shell 13 are respectively connected and fixed with diverter pipes 15;

[0058] The two ends of the diversion spherical shell 13 are respectively provided with diversion bins 16, the upper ends of the two diversion bins 16 are connected to the inlet pipe 14, and the lower ends of the two diversion bins 16 are respectively connected to the two diversion pipes 15. The interior of the diversion spherical shell 13 is provided with a diversion plate that separates the two diversion bins 16.

[0059] The working principle and beneficial effects of this embodiment are as follows: raw materials are added through the inlet pipe 14, which is sealed and connected to the main pipe, and then diverted to the diversion chamber 16 through the inlet pipe 14, and continuously diverted to the two diversion pipes 15 through the diversion chamber 16, and then guided to the designated diversion pipeline through the two diversion pipes 15;

[0060] A diversion plate is provided inside the diversion spherical shell 13 to separate the two diversion chambers 16, thereby avoiding uneven diversion. Specific implementation method seven:

[0062] like Figure 1 — Figure 11 As shown, a new wear-resistant ball valve, the middle end of the diverter ball shell 13 is provided with a central detection diverter groove 23, the central detection diverter groove 23 is connected to the inlet pipe 14, and a pressure detection diverter 17 is inserted into the central detection diverter groove 23;

[0063] A buffer bin is provided between the central sphere 9 and the inner wall of the diverter spherical shell 13 , and the lower end of the buffer bin is connected to the two diverter bins 16 respectively.

[0064] The working principle and beneficial effects of this embodiment are as follows: the upper end of the central detection diverter groove 23 is directly opposite to the inlet pipe 14, and the pressure detection diverter 17 is inserted into the central detection diverter groove 23, and the diversion buffering effect after the pressure detection effect is realized through the pressure detection diverter 17, thereby effectively performing the buffering and pressure reduction effect in the first time. Specific implementation method eight:

[0066] like Figure 1 — Figure 11 As shown, a new type of wear-resistant ball valve, the pressure detection diverter 17 includes a diverter sliding seat 18, the lower end of the diverter sliding seat 18 is arc-shaped and slides in the inner sliding ball groove 10, and the upper end of the diverter sliding seat 18 is longitudinally inserted with a pressure buffer detection seat 19, and the pressure buffer detection seat 19 is inserted in the central detection diverter groove 23.

[0067] The working principle and beneficial effects of this embodiment are as follows: by using a diversion sliding seat 18 on the rotating central sphere 9, the diversion sliding seat 18 is limitedly slid in the inner sliding ball groove 10, and the pressure buffer detection seat 19 is inserted into the central detection diversion groove 23, and then when the pressure is too high, the pressure buffer detection seat 19 is disengaged from the insertion in the central detection diversion groove 23, and then, driven by the central sphere 9, it rotates and disengages from the central detection diversion groove 23, so that the raw material with high pressure can be buffered and flow into the buffer bin provided between the central sphere 9 and the inner wall of the diversion ball shell 13, so that it can be buffered in the first time until the pressure is relieved, and the pressure buffer detection seat 19 is re-inserted into the central detection diversion groove 23 after rotation to perform automatic detection. The raw material in the buffer bin flows into the two diversion bins 16 through the opening at the lower end and flows out through the two diversion pipes 15; when the raw material pressure is too low, the pressure buffer detection seat 19 can be inserted into the inlet pipe 14 through the setting of the pressure detection spring 21 for effective diversion and coordination to prevent uneven addition and diversion. Specific implementation method nine:

[0069] like Figure 1 — Figure 11 As shown, a new wear-resistant ball valve, the pressure buffer detection seat 19 slides longitudinally in the diverter sliding seat 18 through the limit platform and the sealing ring on the outer wall, and a pressure detection spring 21 is provided in the diverter sliding seat 18;

[0070] The pressure detection spring 21 is arranged between the pressure buffer detection seat 19 and the diverter sliding seat 18 .

[0071] The working principle and beneficial effects of this embodiment are as follows: the pressure detection spring 21 is precisely tested before use, so that it is convenient to use within different pressure ranges. When the flow pressure of the raw material is large, the pressure detection spring 21 is compressed between the pressure buffer detection seat 19 and the diversion sliding seat 18. When the flow pressure of the raw material is small, the pressure buffer detection seat 19 is squeezed upward and inserted into the central detection diversion groove 23 or the inlet pipe 14; and then, through the use of the pressure detection spring 21, the situation of the ball friction and hard use in the ball valve principle is effectively reduced, thereby effectively solving the problem that the hard friction between the balls or the sealing rings for a long time can easily cause wear and reduce the long-term service life.

[0074] The working principle and beneficial effects of this embodiment are as follows: after the pressure buffer detection seat 19 is squeezed, the sliding ball 20 at the upper end rotates in the inner ball groove, effectively reducing the friction force during the sliding process of the diverter ball shell 13.
