Description

Technical Field

[0001] This utility model relates to the technical field of safety ball valves for bladder accumulators, and more specifically, to safety ball valves for bladder accumulators. Background Technology

[0002] In the current technological context, safety ball valves for bladder accumulators play a crucial role in industrial applications as a key safety protection device. However, existing safety ball valves have limitations when facing high sealing pressure environments. When the sealing pressure exceeds the equipment's tolerance limit, this excessive pressure may damage the safety ball valve. This damage not only reduces the valve's service life but, more importantly, may trigger a safety accident, threatening the safety of the equipment and operators.

[0003] Furthermore, existing safety ball valves for bladder accumulators also present inconveniences in terms of pressure relief. In actual operation, if it is necessary to reduce system pressure to avoid damage or for maintenance purposes, existing equipment often lacks a simple and quick pressure relief mechanism. This means that when faced with a situation requiring pressure relief, operators may need to take complex steps or use additional tools to complete the process, which not only increases the complexity of the operation but also prolongs the emergency response time.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety ball valve for bladder accumulators, comprising a valve body installed on an external device, a pressure relief mechanism provided on the valve body, the pressure relief mechanism comprising a sealing mechanism, a pressure relief pipe, an external connecting pipe, a sealing disc, a one-way sleeve, a spring, a limit rod, a threaded ring, and an adjustment mechanism, wherein the sealing mechanism is installed on the valve body, the pressure relief pipe is installed on the valve body, the external connecting pipe is installed on the pressure relief pipe and connected to the external device, the one-way sleeve is installed inside the pressure relief pipe, the sealing disc is slidably connected inside the one-way sleeve, the threaded ring is threadedly connected inside the pressure relief pipe, the limit rod is installed on the sealing disc, a spring is sleeved on the limit rod, the two ends of the spring are respectively connected to the threaded ring and the sealing disc, and the adjustment mechanism is installed on the pressure relief pipe.

[0008] The present invention is further configured such that the adjusting mechanism includes a threaded section and a compression spring. The threaded section is threadedly connected to the pressure relief pipe, and the spring is installed on the threaded section and abuts against the sealing disc. This design enables the adjusting mechanism to precisely control the position of the sealing disc, thereby achieving the adjustment of the pressure relief.

[0009] The present invention is further configured such that an intermediate rod is coaxially provided on the sealing disc, and the intermediate rod is slidably connected in the threaded section. This structural design allows the intermediate rod to slide as the threaded section rotates.

[0010] The present invention is further configured such that a rubber ring and a rotating disk are respectively provided at both ends of the threaded section, and the rubber ring is attached to the inside of the pressure relief pipe. This design enables the rubber ring to provide a sealing effect and prevent pressure leakage in the pressure relief pipe.

[0011] The present invention is further configured such that a hexagonal groove is provided on the threaded section, and the hexagonal groove and the threaded section are coaxially arranged. This design allows the operator to easily rotate the threaded section using tools such as a hexagonal wrench to adjust the pressure relief.

[0012] The present invention is further configured such that the sealing mechanism includes a ball and a handle, the ball being rotatably connected to the valve body, a rotating rod being provided on the ball, and the handle being installed on the rotating rod. This design allows the operator to control the rotation of the ball by rotating the handle, thereby realizing the opening or sealing of the valve body.

[0013] The present invention is further configured such that a through groove is provided on the sphere and a pressure relief groove is provided on the side wall of the sphere. This design allows the through groove to communicate with the valve body when the sphere rotates, thereby opening the valve body. When the through groove is sealed, the pressure can be released to the outside through the pressure relief groove, protecting the valve body from damage.

[0014] The present invention is further configured such that an outlet hole is provided on the lower end face of the valve body and the ball, and a pressure relief pipe is connected in the outlet hole.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a special safety ball valve for bladder accumulators, which has the following advantages:

[0017] 1. Pressure Relief Mechanism: This mechanism provides a reliable and flexible pressure relief system. Through the connection of the pressure relief pipe and the external pipe, and the configuration of the one-way sleeve and the sealing disc, this mechanism can effectively release internal pressure to the outside. When the system pressure exceeds the set value, the sealing disc will separate from the one-way sleeve, allowing the pressure to be discharged through the pressure relief pipe and the external pipe, thereby protecting the valve body from overpressure damage. In addition, the setting of the limit rod and spring ensures the stable sealing of the sealing disc under normal operating conditions, while allowing for rapid pressure relief when needed.

[0018] 2. The adjusting mechanism allows the operator to precisely adjust the position of the sealing disc by rotating the threaded section, thereby controlling the pressure relief. The pressure spring provides restoring force during the adjustment process, ensuring that the sealing disc works stably in the set position. This design allows the operator to adjust the pressure relief according to actual needs, improving the safety and adaptability of the equipment.

[0019] 3. The sealing mechanism, through the rotating connection between the ball and the valve body, and the design of the through groove and pressure relief groove, enables the valve body to be quickly opened and sealed when needed. The configuration of the handle and rotating rod allows the operator to easily control the rotation of the ball, thereby opening or sealing the valve body. When the system pressure is too high, the sealing disc will separate from the one-way sleeve, and the overpressure will be released to the outside through the pressure relief groove and the outlet hole, protecting the valve body from damage. This design not only improves the safety of the equipment, but also simplifies the operation process and improves work efficiency. Attached Figure Description

[0029] Please see Figure 1-5 A safety ball valve for bladder accumulators includes a valve body 1, which is installed on an external device. The valve body 1 is equipped with a pressure relief mechanism, which includes a sealing mechanism, a pressure relief pipe 2, an external connecting pipe 3, a sealing disc 4, a one-way sleeve 5, a spring 6, a limit rod 7, a threaded ring 8, and an adjusting mechanism. The sealing mechanism is installed on the valve body 1, the pressure relief pipe 2 is installed on the valve body 1, the external connecting pipe 3 is installed on the pressure relief pipe 2 and connected to the external device, the one-way sleeve 5 is installed inside the pressure relief pipe 2, the sealing disc 4 is slidably connected inside the one-way sleeve 5, the threaded ring 8 is threadedly connected inside the pressure relief pipe 2, and the limit rod 7 is installed on the sealing disc 4. A spring 6 is sleeved on the rod 7. The two ends of the spring 6 are connected to the threaded ring 8 and the sealing plate 4, respectively. The adjustment mechanism is installed on the pressure relief pipe 2. The adjustment mechanism includes a threaded section 9 and a compression spring 10. The threaded section 9 is threadedly connected to the pressure relief pipe 2. The spring 6 is installed on the threaded section 9 and abuts against the sealing plate 4. A middle rod 11 is coaxially provided on the sealing plate 4. The middle rod 11 is slidably connected in the threaded section 9. A rubber ring 12 and a rotating disk 13 are provided at both ends of the threaded section 9, respectively. The rubber ring 12 fits in the pressure relief pipe 2. A hexagonal groove 14 is opened on the threaded section 9. The hexagonal groove 14 and the threaded section 9 are coaxially arranged.

[0030] In this embodiment, when pressure needs to be adjusted, the threaded section 9 is rotated, which moves the threaded section 9 toward the outer pipe 3. At this time, the compression spring 10 is compressed, which causes the sealing disc 4 to move toward the threaded ring 8, thereby increasing the pressure relief. When pressure needs to be reduced, the intermediate disc is rotated because the limiting rod 7 is slidably connected to the threaded ring 8. Then, the rotation of the threaded ring 8 causes the spring 6 to press against the sealing disc 4, thereby reducing the sealing pressure and completing the adjustment process.

[0031] Please see Figure 1 and Figure 2 As one embodiment of the sealing mechanism: the sealing mechanism includes a ball 15 and a handle 16. The ball 15 is rotatably connected inside the valve body 1. A rotating rod 17 is provided on the ball 15. The handle 16 is installed on the rotating rod 17. A through groove 18 is provided on the ball 15. A pressure relief groove 19 is provided on the side wall of the ball 15. Outflow holes 20 are respectively provided on the lower end faces of the valve body 1 and the ball 15. The pressure relief pipe 2 is connected to the outflow holes 20.

[0032] More specifically, when valve body 1 needs to be opened, the handle 16 first drives the ball 15 to rotate, so that the through groove 18 is connected to valve body 1, thus completing the connection process. When sealing is required, the through groove 18 is sealed, and then the outside is connected to the pressure relief groove 19. Then the pressure is pressed against the sealing disc 4. When the pressure is too high, the seal will be broken, and the pressure relief process is completed, thereby protecting valve body 1.

[0033] In summary, during the use or operation of the overall equipment: when pressure adjustment is required, rotating the threaded section 9 moves it towards the outer pipe 3, compressing the spring 10 and causing the sealing disc 4 to move towards the threaded ring 8, thus increasing the pressure relief. When pressure reduction is required, rotating the intermediate disc, with the limit rod 7 slidingly connected to the threaded ring 8, causes the spring 6 to press against the sealing disc 4, reducing the sealing pressure and completing the adjustment process. When opening the valve body 1, the handle 16 rotates the ball 15, connecting the through groove 18 to the valve body 1, completing the connection process. When sealing is required, the through groove 18 seals, connecting to the outside through the pressure relief groove 19, where pressure presses against the sealing disc 4. When the pressure is too high, the seal is released, completing the pressure relief process and protecting the valve body 1.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
