Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a turbine ball valve that is easy to maintain. Background Technology

[0002] Ball valves are widely used in various fields. Their superior quality and high-performance stability are unmatched by ordinary cast steel ball valves. The service life of fully welded ball valves is much longer than that of cast steel ball valves. Fully welded ball valves are widely used in various pipeline equipment such as urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, and power plants. Among them, large-diameter turbine welded ball valves play an important role as a type of welded ball valve.

[0003] Traditional turbine ball valves, during long-term use, are prone to accumulating impurities in the valve core, which are difficult to clean and affect the valve's sealing performance and service life. Furthermore, damage to the valve core is difficult to detect in real time, requiring valve disassembly for maintenance, which is cumbersome, time-consuming, and labor-intensive, and can also affect the normal operation of related systems. In addition, the external environment can easily contaminate the internal components of the valve during maintenance, further reducing the effectiveness of maintenance and the reliability of valve use. Therefore, a turbine ball valve that is easier to maintain is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a turbine ball valve that is easy to maintain, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a turbine ball valve that is easy to maintain, comprising a valve body, an externally connected maintenance groove, an internally fixedly connected maintenance box, an internally fixedly connected baffles, a slidably connected high-elasticity rubber block on one side of each baffle, and a fixedly connected sealing block on the side of the high-elasticity rubber block away from the baffle, the sealing block being attached to the outer wall of the valve core, an externally connected impurity accumulation groove, an ultrasonic detection structure installed inside the maintenance box, the detection end of the ultrasonic detection structure being attached to the outer wall of the valve core, and a cleaning structure connected inside the impurity accumulation groove.

[0006] As a further preferred embodiment of this technical solution: the ultrasonic detection structure includes a miniature ultrasonic generator, which is fixedly connected to the inside of the inspection box. An ultrasonic detection head is connected to the outside of the miniature ultrasonic generator via a wire. The detection end of the ultrasonic detection head penetrates the outer walls of the high-elasticity rubber block and the sealing block respectively and is parallel to the curved surface of the sealing block.

[0007] As a further preferred embodiment of this technical solution: the cleaning structure includes an air intake pipe, which is fixedly connected to the inside of the high-elasticity rubber block. One end of the air intake pipe passes through the outside of the high-elasticity rubber block and the sealing block, respectively. An air jet cleaning hole is provided inside the impurity accumulation groove. A one-way valve cover is hinged to the outside of the air jet cleaning hole. One end of the air intake pipe is connected to the air jet cleaning hole.

[0008] As a further preferred embodiment of this technical solution: the other end of the air intake pipe is connected to a connecting tapered pipe.

[0009] As a further preferred embodiment of this technical solution: a spring is fixedly connected to the outside of the high-elasticity rubber block, and a compression block is fixedly connected to the end of the spring away from the high-elasticity rubber block, and the compression block is attached to the inner wall surface of the inspection box.

[0010] As a further preferred embodiment of this technical solution: the outer surface of the impurity accumulation tank is integrally formed with a guide edge, which is used to guide the impurities remaining on the outside of the valve core into the interior of the impurity accumulation tank.

[0011] As a further preferred embodiment of this technical solution: the outer surface of the sealing block is fixedly connected with multiple sealing rings, and the outer wall of the sealing rings is press-fitted with the inner wall of the connecting inspection groove.

[0012] As a further preferred embodiment of this technical solution: the outside of the maintenance box is snapped with a sealing side cover, which is used to seal the maintenance box and reduce the impact of the external environment on the internal components of the maintenance box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, an external maintenance channel is constructed by connecting the maintenance slot and the maintenance box. With the online detection of the ultrasonic detection structure and the removal of impurities by the cleaning structure, the valve core can be inspected and impurities cleaned without disassembling the entire ball valve, which greatly simplifies the maintenance process and saves maintenance time and labor costs.

[0015] 2. In this utility model, impurities on the valve core surface are actively collected by the impurity accumulation groove, which reduces the wear of impurities on the valve core sealing surface. The sealing block and the high-elasticity rubber block work together to enhance the sealing effect. The dual effect extends the service life of the valve core and improves the overall sealing reliability of the ball valve. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1

[0024] Please see Figures 1-5 This utility model provides a technical solution: a turbine ball valve that is easy to maintain, including a valve body 1, a connecting maintenance groove 2 on the outside of the valve body 1, a maintenance box 3 fixedly connected inside the connecting maintenance groove 2, two baffles 4 fixedly connected inside the maintenance box 3, a high-elasticity rubber block 5 slidably connected to one side of the baffle 4, and a sealing block 6 fixedly connected to the side of the high-elasticity rubber block 5 away from the baffle 4, the sealing block 6 being attached to the outer wall of the valve core, an impurity accumulation groove 11 on the outside of the sealing block 6, an ultrasonic detection structure installed inside the maintenance box 3, the detection end of the ultrasonic detection structure being attached to the outer wall of the valve core, and a cleaning structure connected inside the impurity accumulation groove 11.

[0025] In this embodiment, specifically: during use, a maintenance box 3, which serves as a protection and installation carrier, is fixedly connected inside the maintenance slot 2. Two baffles 4, which limit and guide the high-elasticity rubber block 5, are fixedly connected inside the maintenance box 3. The two baffles 4 limit the high-elasticity rubber block 5, ensuring that it does not detach from the maintenance box 3 during use. Furthermore, the high-elasticity rubber block 5 will drive a sealing block 6, which directly adheres to the outer wall of the valve core and serves as both an auxiliary seal and component installation, to be fixedly connected to the side away from the baffles 4. The sealing block 6 has an impurity accumulation groove 11 on its exterior for collecting impurities from the valve core surface. The impurity accumulation groove 11 can cooperate with the sealing block during use. Block 6 achieves the fit of the valve core, and by using the impurity accumulation groove 11, impurities that enter between the valve body 1 and the valve core can be gradually collected during the overall use of the valve body 1. During use, that is, during the rotation of the valve core, the impurities will be continuously transported to the interior of the impurity accumulation groove 11 by the continuous flow of water inside the valve body 1, thereby achieving the function of collecting impurities inside the ball valve. After the high-elastic rubber block 5 and the fitting sealing block 6 are disassembled and cleaned, the valve core can be inspected and observed through the connecting inspection groove 2. The condition of the valve core can be observed from the outside, which is convenient for the valve core to be inspected. At the same time, welding rods and other components can be passed through the outer wall of the valve body 1 to perform welding work on the valve core through the connecting inspection groove 2.

[0026] In this embodiment, specifically: the inspection box 3 is equipped with an ultrasonic detection structure whose detection end is attached to the outer wall of the valve core and can detect valve core damage in real time.

[0027] like Figures 1-5 As shown, the cleaning structure includes an air intake pipe 12, which is fixedly connected to the inside of the high-elasticity rubber block 5. One end of the air intake pipe 12 passes through the outside of the high-elasticity rubber block 5 and the sealing block 6. An air jet cleaning hole 14 is provided inside the impurity accumulation groove 11. A one-way valve cover 15 is hinged to the outside of the air jet cleaning hole 14. One end of the air intake pipe 12 is connected to the air jet cleaning hole 14, and the other end of the air intake pipe 12 is connected to a connecting tapered pipe 13.

[0028] In this embodiment, specifically: during use, a high-pressure air pump is connected via a tapered pipe 13. The high-pressure air pump delivers external gas through the air inlet pipe 12 to the jet cleaning port 14. The high-pressure gas can push open the one-way valve cover 15 and spray out, blowing away the impurities in the impurity accumulation tank 11, thus effectively cleaning the impurities. The one-way valve cover 15 can automatically close when there is no gas delivery, preventing impurities or fluids from entering the air inlet pipe 12. Overall, the impurities located inside the impurity accumulation tank 11 can be cleaned during the maintenance of the valve body 1.

[0029] Example 2

[0030] like Figures 3-5As shown, the ultrasonic detection structure includes a miniature ultrasonic generator 9, which is fixedly connected inside the inspection box 3. An ultrasonic detection head 10 is connected to the outside of the miniature ultrasonic generator 9 via a wire. The detection end of the ultrasonic detection head 10 penetrates the outer walls of the high-elasticity rubber block 5 and the sealing block 6 respectively and is parallel to the curved surface of the sealing block 6.

[0031] In this embodiment, specifically: the miniature ultrasonic generator 9 is connected to the ultrasonic detection head 10, which performs signal transmission and reception, through a wire, and the detection end of the ultrasonic detection head 10 penetrates the outer wall of the high-elastic rubber block 5 and the sealing block 6 and is parallel to the curved surface of the sealing block 6.

[0032] During use, the fixed installation of the miniature ultrasonic generator 9 can avoid external interference and ensure signal stability. The wire connection can reduce signal transmission loss. The probe end penetrates the outer wall and can directly contact the valve core to improve detection accuracy. The setting parallel to the curved surface can ensure that the probe end is in full contact with the outer wall of the valve core because it fits the curved surface of the sealing block 6 and the curvature of the valve core. This enables comprehensive and accurate online non-destructive testing of the valve core and timely detection of problems such as valve core cracks and wear.

[0033] like Figure 5 As shown, a spring 8 is fixedly connected to the outside of the high-elasticity rubber block 5, and a compression block 7 is fixedly connected to the end of the spring 8 away from the high-elasticity rubber block 5. The compression block 7 is attached to the inner wall surface of the inspection box 3.

[0034] In this embodiment, specifically: the spring 8 applies a continuous and stable compressive force to the high-elasticity rubber block 5 through the compression block 7, which can further enhance the tightness of the fit between the high-elasticity rubber block 5 and the sealing block 6 and the outer wall of the valve core. This not only improves the sealing effect, but also ensures the collection efficiency of the impurity accumulation groove 11 on the surface of the valve core, while ensuring stable contact between the ultrasonic detection structure detection end and the valve core, thus improving the detection accuracy.

[0035] like Figure 4 As shown, the impurity accumulation tank 11 has an integrally formed guide edge 18 on its exterior, which is used to guide the impurities remaining on the exterior of the valve core into the interior of the impurity accumulation tank 11.

[0036] In this embodiment, specifically: the impurity accumulation groove 11 is integrally formed with a guide edge 18 on the outside, and the guide edge 18 is used to guide the impurities remaining on the outside of the valve core into the impurity accumulation groove 11. The guide edge 18, through its own inclined setting, can actively guide the impurities on the surface of the valve core to smoothly enter the impurity accumulation groove 11 during the rotation of the valve core, avoiding the impurities from being leaked outside the impurity accumulation groove 11 due to the displacement of the valve core during rotation, further improving the impurity collection efficiency and reducing the wear of impurities on the valve core sealing surface.

[0037] like Figure 3As shown, multiple sealing rings 16 are fixedly connected to the outside of the sealing block 6, and the outer wall of the sealing ring 16 is press-fitted with the inner wall of the connecting inspection groove 2.

[0038] In this embodiment, specifically: multiple sealing rings 16 are fixedly connected to the outside of the sealing block 6, and the outer wall of the sealing ring 16 is tightly fitted with the inner wall of the connecting inspection groove 2. The arrangement of multiple sealing rings 16 can form multiple sealing barriers between the sealing block 6 and the connecting inspection groove 2, effectively preventing fluid or impurities from leaking from the gap between the two, further improving the sealing reliability of the entire ball valve, and avoiding problems such as pipeline leakage and system pollution caused by sealing failure.

[0039] like Figure 1 As shown, the outside of the maintenance box 3 is snapped with a sealing side cover 17, which is used to seal the maintenance box 3 and reduce the impact of the external environment on the internal components of the maintenance box 3.

[0040] In this embodiment, specifically: a sealing side cover 17 is snapped onto the outside of the inspection box 3, and the sealing side cover 17 is used to seal the inspection box 3 to reduce the impact of the external environment on the internal components of the inspection box 3. The sealing side cover 17 can be quickly disassembled and installed. In the closed state, it can isolate external dust, moisture and other impurities, protect the ultrasonic detection structure, cleaning structure and other components inside the inspection box 3 from contamination or damage, and extend the service life of the components. After disassembly, it is convenient for staff to maintain and replace the internal components, further improving the convenience of ball valve maintenance.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
