Description

Technical Field

[0001] This utility model relates to the field of rotary ball valve technology, specifically a bidirectional flow hard-on-hard rotary ball valve with leakage recovery function. Background Technology

[0002] In industrial production, fluid transportation, and various systems involving valve control, valves, as critical fluid control components, are of paramount importance in terms of performance stability and reliability. The bidirectional flow hard-to-hard rotary ball valve, a common valve type, is widely used in numerous fields such as petroleum, chemical, natural gas, and water treatment due to its bidirectional flow and hard seal characteristics.

[0003] However, in actual use, valves are prone to sealing failure due to long-term scouring and corrosion from fluid media, as well as wear and tear on their own components. Once the seal fails, the medium inside the valve will leak. Leaking media not only wastes resources and increases production costs, but may also pollute the surrounding environment. In the case of certain hazardous media leaks, it can even cause serious safety accidents, threatening personnel safety and the normal operation of equipment.

[0004] Most existing valves lack effective leakage collection devices. When a leak occurs, the leaked medium flows freely, causing significant inconvenience to the site and increasing the difficulty and cost of subsequent cleanup. While leakage collection devices have emerged with technological advancements, some are fixedly installed at the bottom of the valve, making installation and removal cumbersome for maintenance. Therefore, developing a bidirectional flow hard-on-hard rotary ball valve with leakage collection capabilities is of significant practical importance. Utility Model Content

[0005] The purpose of this utility model is to provide a bidirectional flow hard-to-hard rotary ball valve with leakage collection function, which solves the problem that most valves lack an effective leakage collection device. When leakage occurs, the leaked medium will flow freely, causing great inconvenience to the site environment and increasing the difficulty and cost of subsequent cleanup work. In addition, some leakage collection devices are fixedly installed at the bottom of the valve, making the installation and removal of the leakage collection device more troublesome when maintenance is required.

[0006] A bidirectional flow hard-to-hard rotary ball valve with leakage collection function includes a valve unit and a leakage collection unit. The leakage collection unit is movably installed at the bottom of the valve unit and includes:

[0007] A funnel seat, which is movably disposed below the valve unit;

[0008] A collection bottle, the top of which is threaded to the bottom of a funnel base;

[0009] A fixing component is provided on the funnel seat and is used to fix the funnel seat and the valve unit.

[0010] Preferably, the valve unit includes:

[0011] Valve body;

[0012] A valve disc, which is rotatably connected to the valve body;

[0013] Valve stem, which is fixedly connected to valve disc;

[0014] The base is fixedly connected to the bottom end of the valve body, and the base is rotatably connected to the bottom end of the valve stem;

[0015] A valve cover, which is fixedly connected to the top of the valve body;

[0016] A drive assembly, which is mounted on the valve cover.

[0017] Preferably, the funnel seat is fitted onto the outside of the base.

[0018] Preferably, a fixing block is fixedly connected to each side of the funnel seat.

[0019] Preferably, the fixing component includes:

[0020] An extrusion block, which is slidably connected above the funnel seat;

[0021] A slide bar, one end of which is fixedly connected to the extrusion block;

[0022] A spring, which is sleeved on the outside of the slide rod;

[0023] A rotating block is rotatably connected to the other end of the slide rod.

[0024] Preferably, the compression block is in movable contact with the base.

[0025] Preferably, the rotating block and the fixed block are in movable contact.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This bidirectional flow hard-on-hard rotary ball valve with leakage collection function is equipped with a leakage collection unit. By fitting the funnel seat onto the outside of the base, rotating the rotating block prevents it from abutting against the fixed block. Under the action of the spring, the squeezing block is squeezed, causing it to abut against the base, which can firmly fix the funnel seat to the bottom of the valve unit. When disassembling, pulling the rotating block moves the sliding rod, which in turn moves the squeezing block outward. At the same time, the spring is squeezed, and rotating the rotating block makes it engage with the fixed block, allowing the funnel seat to be removed from the base. This makes the installation and removal of the leakage collection unit convenient and the maintenance process more efficient. Attached Figure Description

[0036] Example 1

[0037] A bidirectional flow hard-to-hard rotary ball valve with leakage collection function includes a valve unit 1 and a leakage collection unit 2. The leakage collection unit 2 is movably installed at the bottom of the valve unit 1 and includes:

[0038] Funnel seat 21, which is movably disposed below valve unit 1;

[0039] The top of the collection bottle 22 is threaded to the bottom of the funnel seat 21;

[0040] Fixing component 23 is disposed on funnel seat 21 and is used to fix funnel seat 21 and valve unit 1.

[0041] Furthermore, valve unit 1 includes:

[0042] Valve body 11;

[0043] Valve disc 12 is rotatably connected inside valve body 11;

[0044] Valve stem 13, which is fixedly connected to valve disc 12;

[0045] The base 14 is fixedly connected to the bottom end of the valve body 11, and the base 14 is rotatably connected to the bottom end of the valve stem 13.

[0046] Valve cover 15 is fixedly connected to the top of valve body 11;

[0047] The drive assembly 16 is mounted on the valve cover 15. The drive assembly 16 drives the valve stem 13 to rotate. Since the valve stem 13 is fixedly connected to the valve disc 12, the rotation of the valve stem 13 causes the valve disc 12 to rotate within the valve body 11, thereby opening and closing the valve and controlling the bidirectional flow of fluid. A hard seal is used between the valve disc 12 and the valve body 11. Through the tight contact between the sealing surfaces of the valve disc 12 and the valve body 11, good sealing performance is ensured when the valve is closed, preventing fluid leakage.

[0048] Example 2

[0049] A bidirectional flow hard-to-hard rotary ball valve with leakage collection function includes a valve unit 1 and a leakage collection unit 2. The leakage collection unit 2 is movably installed at the bottom of the valve unit 1 and includes:

[0050] Funnel seat 21, which is movably disposed below valve unit 1;

[0051] The top of the collection bottle 22 is threaded to the bottom of the funnel seat 21. The collection bottle 22 and the funnel seat 21 are connected by a threaded connection. This connection method is simple and reliable, and facilitates the installation and disassembly of the collection bottle 22. It is convenient to deal with the collected leakage, and it is also beneficial to clean and maintain the collection bottle 22.

[0052] A fixing component 23 is mounted on the funnel seat 21 and is used to fix the funnel seat 21 to the valve unit 1. When the valve fails to seal due to long-term use or other reasons, resulting in media leakage, the leaked media will flow out from the bottom of the valve. At this time, the leakage collection unit 2 located at the bottom of the valve unit 1 begins to function. The funnel seat 21 is fitted onto the outside of the base 14 and can effectively collect the media leaking from the valve base 14, allowing the media to flow into the collection bottle 22 below it along the shape of the funnel seat 21. The collection bottle 22 is connected to the funnel seat 21 by threads, which facilitates disassembly and installation. When the collection bottle 22 has collected a certain amount of leakage, it can be unscrewed from the funnel seat 21 to treat the leakage.

[0053] Furthermore, the funnel seat 21 is fitted onto the outside of the base 14.

[0054] Furthermore, fixing blocks 211 are fixedly connected to both sides of the funnel seat 21.

[0055] Furthermore, the fixing component 23 includes:

[0056] The extrusion block 231 is slidably connected above the funnel seat 21;

[0057] Slide rod 232, one end of which is fixedly connected to extrusion block 231;

[0058] Spring 233 is sleeved on the outside of slide bar 232;

[0059] Rotating block 234 is rotatably connected to the other end of slide rod 232. By fitting funnel seat 21 onto the outside of base 14, rotating rotating block 234 prevents it from abutting against fixed block 211. Under the action of spring 233, squeezing block 231 is squeezed, causing squeezing block 231 to abut against base 14, thus firmly fixing funnel seat 21 to the bottom of valve unit 1. During disassembly, pulling rotating block 234 moves slide rod 232, which in turn moves squeezing block 231 outward. At the same time, spring 233 is squeezed, and rotating rotating block 234 engages with fixed block 211, allowing funnel seat 21 to be removed from base 14. This makes the installation and disassembly of leakage collection unit 2 more convenient and the maintenance process more efficient.

[0060] Furthermore, the compression block 231 makes active contact with the base 14.

[0061] Furthermore, the rotating block 234 and the fixed block 211 are in movable contact.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
