Description

Technical Field

[0001] This utility model relates to the field of ceramic ball valve technology, specifically a two-piece ceramic ball valve. Background Technology

[0002] The two-piece ceramic ball valve combines modern manufacturing processes with innovative design. The ball is made of high-performance ceramic material, which has excellent wear resistance and corrosion resistance, and can cope with various harsh working conditions. The two-piece structure facilitates installation and maintenance, effectively reducing the cost of use. It is widely used in chemical, petroleum and power industries and is a reliable control element in modern industrial pipeline systems.

[0003] Existing two-piece ceramic ball valves use high-performance ceramic materials for the ball, possessing superior wear and corrosion resistance, capable of handling various harsh working conditions, and facilitating the transport and shut-off of corrosive liquids. They are reliable control components in modern industrial pipeline systems. However, most two-piece ceramic ball valves use stainless steel or alloys for the valve body and its surface components. These are prone to deformation when subjected to strong impacts during transportation or use, leading to malfunctions and even leaks later in use. Furthermore, the individual stop on the valve body does not provide sufficient security for the handle when the valve is closed, posing a risk of leakage. To address these shortcomings, this invention provides a two-piece ceramic ball valve to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a two-piece ceramic ball valve, which solves the problems of easy deformation of the valve body when subjected to strong impacts, leading to malfunctions during use, and the risk of leakage due to insufficient secure fixation of the handle by a single stop.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a two-piece ceramic ball valve, including a valve body, a handle provided on the valve body, a protective cover provided on the outside of the valve body, a groove provided on the protective cover, and a limiting component provided inside the protective cover, the limiting component being used to limit the handle;

[0006] The limiting component includes:

[0007] A cavity, which is located inside a protective cover;

[0008] A spring, one end of which is fixedly connected to the cavity;

[0009] The slider is slidably connected inside the cavity, and the other end of the spring is fixedly connected to the slider.

[0010] Preferably, a stop is threaded onto the valve body, the handle is located on the upper end of the stop, a valve stem is fixedly connected to one end of the handle, and a fixing member is threaded onto the valve stem.

[0011] Preferably, threaded pipe connections are fixedly connected to both ends of the valve body, and an inlet is provided at the end of the valve body near the threaded pipe connection.

[0012] Preferably, a locking block is fixedly connected to the end of the slider away from the spring, and the end of the locking block away from the slider abuts against the top of the slot.

[0013] Preferably, the card block and the slider are integrally formed.

[0014] Preferably, the protective cover has a chamber inside, and a fixing ring is fixedly connected to the inner wall of the protective cover, with the valve body abutting against the fixing ring.

[0015] This utility model discloses a two-piece ceramic ball valve, which has the following beneficial effects: The two-piece ceramic ball valve adopts a structure in which a protective cover is fixedly connected to the outside of the valve body. The protective cover can effectively protect the valve body and surface parts during transportation or use, preventing the valve body surface from being deformed by impact, which could lead to malfunctions or even leakage in the later use of the ceramic ball valve. At the same time, the limiting component set in the protective cover can limit the handle after the valve is closed. The locking block in the limiting component abuts against the groove of the handle and the protective cover, which can stably fix the handle and prevent leakage after the valve is closed.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This application provides a two-piece ceramic ball valve that solves the problems of easy deformation of the valve body 1 under strong impact leading to malfunctions during use, and the risk of leakage due to insufficient fixation of the handle 3 by a single stop 31. The solution is to use a structure in which a protective cover 2 is fixedly connected to the outside of the valve body 1. The protective cover 2 can effectively protect the valve body 1 and its surface components during transportation or use, preventing deformation of the valve body 1 surface due to impact, which could lead to malfunctions or even leakage in the later use of the ceramic ball valve. Simultaneously, the limiting component 4 inside the protective cover 2 can limit the handle 3 after the valve is closed. The locking block 44 inside the limiting component 4 abuts against the handle 3 and the groove 21 inside the protective cover 2, stably fixing the handle 3 and preventing leakage after the valve is closed.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1;

[0026] This utility model discloses a two-piece ceramic ball valve, according to the attached... Figure 1-4 As shown, the valve body 1 constitutes the main structure of the ball valve, supporting and protecting the internal components. A handle 3 is provided on the valve body 1. A protective cover 2 is provided on the outside of the valve body 1. A groove 21 is provided on the protective cover 2. A limit component 4 is provided inside the protective cover 2. The limit component 4 is used to limit the handle 3.

[0027] Limiting component 4 includes:

[0028] Cavity 41 is provided inside the protective cover 2, and other components of the limiting assembly 4 are easily assembled inside cavity 41;

[0029] Spring 42, one end of which is fixedly connected to cavity 41, controls slider 43 to reset;

[0030] The slider 43 is slidably connected inside the cavity 41, and the other end of the spring 42 is fixedly connected to the slider 43.

[0031] A locking block 44 is fixedly connected to the end of slider 43 away from spring 42, and the end of locking block 44 away from slider 43 abuts against the top of slot 21.

[0032] The card block 44 and the slider 43 are integrally formed, and the integrally formed structure is more stable.

[0033] The protective cover 2 has a chamber 23 inside, and a fixing ring 22 is fixedly connected to the inner wall of the protective cover 2. The valve body 1 abuts against the fixing ring 22.

[0034] After the valve is closed by rotating the handle 3, the single stop 31 on the valve body 1 fixes the handle 3, and at the same time, the locking block 44 in the limiting component 4 also limits the handle 3 as a safety measure to prevent leakage. First, the sliding slider 43 drives the locking block 44 to compress the spring 42, so that the locking block 44 is completely retracted into the cavity 41. Then, the handle 3 is rotated 90 degrees to reach the slot 21 of the protective cover 2. Then, the slider 43 is released, and the spring 42 controls the slider 43 to reset. The slider 43 drives the locking block 44, which is integrally formed with it, to reset. One end of the locking block 44 abuts against the top of the slot 21, and the side of the locking block 44 abuts against the handle 3, effectively limiting the handle 3 as a safety measure to prevent leakage after the valve is closed.

[0035] Example 2;

[0036] This utility model discloses a two-piece ceramic ball valve, according to the attached... Figure 1-4 As shown, the valve body 1 constitutes the main structure of the ball valve, supporting and protecting the internal components. A handle 3 is provided on the valve body 1. A protective cover 2 is provided on the outside of the valve body 1. A groove 21 is provided on the protective cover 2. A limit component 4 is provided inside the protective cover 2.

[0041] A stop 31 is threaded onto the valve body 1. A handle 3 is located on the upper end of the stop 31. A valve stem 33 is fixedly connected to one end of the handle 3. The valve stem 33 is used to connect the manual operation handle 3 and the ball, transmitting operating force so that the ball can rotate around the center line of the valve body 1, thereby realizing the opening and closing of the valve. The ball, as the closing element of the ball valve, controls the flow of the medium by rotating. The ceramic ball has excellent wear resistance and corrosion resistance, and is suitable for various harsh working conditions. A fixing part 32 is threaded onto the valve stem 33.

[0042] The valve body 1 has threaded pipe connection ports 11 fixedly connected to both ends, and a liquid inlet port 12 is provided at the end of the valve body 1 near the threaded pipe connection port 11.

[0043] The structure of the protective cover 2 fixedly connected to the outside of the valve body 1 can effectively protect the valve body 1 and its surface parts during transportation or use, preventing the surface of the valve body 1 from being deformed by impact, which could lead to malfunctions or even leakage in the later use of the ceramic ball valve. When using this two-piece ceramic ball valve, first connect the water pipe to the threaded pipe connection port 11 of the valve body 1, and then rotate the handle 3 to drive the valve stem 33 fixedly connected to it to rotate. The valve stem 33 is fixedly connected to the ceramic ball, which makes it easy to rotate the ceramic ball to connect the two-piece ceramic ball valve. The water gate can be opened and the liquid can enter the ball valve through the liquid inlet 12. The handle 3 can be used to control the opening and closing of the ball valve, thereby achieving the purpose of controlling the flow of liquid.
