Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a handle-type ball valve. Background Technology

[0002] A ball valve achieves its seal through the cooperation of a sealing element installed in the valve body and a ball-shaped valve core. Depending on the operating environment, the valve core is usually made of ordinary steel or stainless steel, while the sealing element that matches the valve core is usually made of plastic. Ball valves can be used for fluid regulation and control. In pipelines, ball valves can not only flexibly control the merging, splitting, and switching of the flow direction of the medium, but also close any channel while connecting the other two channels. Ball valves are classified into pneumatic ball valves, electric ball valves, and manual ball valves according to their driving method.

[0003] Existing manual ball valves control flow by directly pushing the handle, lacking a mechanism to prevent accidental operation. Workers may inadvertently touch the handle, altering the flow inside the ball valve and affecting the production process, potentially causing production interruptions or even safety accidents.

[0004] Therefore, there is an urgent need to provide a handle-type ball valve to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a handle-type ball valve.

[0006] To solve the above-mentioned technical problems, the present invention provides a handle-type ball valve, including a valve body, a first sealing element threadedly installed at one end of the valve body, a second sealing element threadedly installed at the other end of the valve body, a sealing bolt threadedly installed at the bottom end of the valve body with one end penetrating and extending into the interior of the first sealing element, an installation mechanism provided at the top end of the valve body, and a connecting mechanism provided inside the installation mechanism.

[0007] With the above technical solution, a first sealing element and a second sealing element are threadedly installed on both sides of the valve body, and the first sealing element and the second sealing element are fixed by sealing element bolts to prevent the first sealing element and the second sealing element from loosening.

[0008] The present invention is further configured such that: the mounting mechanism includes a threaded cylinder fixed to the top of the valve body, and a valve stem is rotatably mounted inside the threaded cylinder.

[0009] The valve stem is installed using the above technical solution via a threaded cylinder.

[0010] The present invention is further configured such that: a valve core is threadedly installed at one end of the valve stem, and the two sides of the valve core are respectively sealed to one end of the first sealing element and the second sealing element; a rubber ring is sealed between the outer surface of the valve stem and the inner wall of the threaded cylinder.

[0011] With the above technical solution, the valve stem is sealed by a rubber ring and a threaded cylinder to prevent water vapor from seeping out between the threaded cylinder and the valve stem. The valve stem can drive the valve core to rotate, thereby controlling the opening and closing of the ball valve. The first and second sealing elements prevent water vapor from seeping out through both sides of the valve core.

[0012] The present invention is further configured such that: a fixing cylinder is threadedly installed on the outer surface of the threaded cylinder, and a fixing bolt with one end penetrating through and extending into the interior of the threaded cylinder is installed on the external thread of the fixing cylinder.

[0013] The above technical solution limits the valve stem tip by using a fixed cylinder to prevent the valve stem from loosening from the valve core, and the fixing bolts prevent the fixed cylinder and threaded cylinder from loosening.

[0014] The present invention is further configured such that: the connecting mechanism includes a cylindrical spring sleeved on the top of the valve stem, the top of the cylindrical spring abuts against a rotating seat, and a connecting block is fixedly installed on the top of the rotating seat.

[0015] Through the above technical solution, the cylindrical spring drives the rotating seat and the connecting block to maintain an upward extension posture, and the fixed cylinder limits the top of the rotating seat.

[0016] The present invention is further configured such that: a block sleeve is fitted and installed on the outer surface of the connecting block; a sleeve bolt with one end penetrating through and extending into the interior of the connecting block is installed on the external thread of the block sleeve; and a ball valve handle is fixedly installed on the outside of the block sleeve.

[0017] The above technical solution uses sleeve bolts to fix the square sleeve and connecting block, allowing the ball valve handle to drive the rotating seat to rotate and rise.

[0018] The present invention is further configured such that: a first impeller is fixedly installed at one end of the rotating seat, and a second impeller is fixedly installed at the top end of the valve stem.

[0019] The above technical solution involves rotating the ball valve handle to move the rotating seat and the first impeller downwards and connect them with the second impeller of the valve stem, thereby driving the valve stem and valve core to rotate.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model has a connecting mechanism, so the rotating seat and valve stem are normally separate. Only when operating can they be connected so that the valve core can be controlled through the ball valve handle. This ensures the stability of the ball valve during operation and can effectively avoid production interruptions or safety problems caused by personnel accidentally touching the ball valve.

[0022] 2. This utility model, by providing an installation mechanism, designs the main components of the ball valve as independent modules, which facilitates disassembly and installation. This allows maintenance personnel to quickly and accurately locate and replace the damaged parts when the ball valve is damaged, greatly shortening the maintenance time. Furthermore, each component can be upgraded or replaced individually to adapt to different working environments, which helps to extend the service life of the ball valve. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figures 1-4A handle-type ball valve includes a valve body 1. A first sealing element 2 is threaded onto one end of the valve body 1, and a second sealing element 3 is threaded onto the other end of the valve body 1. A sealing bolt 4, with one end penetrating and extending into the first sealing element 2, is threaded onto the bottom end of the valve body 1. A mounting mechanism 5 is provided at the top end of the valve body 1. The mounting mechanism 5 includes a threaded cylinder 501 fixed to the top end of the valve body 1. A valve stem 502 is rotatably mounted inside the threaded cylinder 501. A valve core 503 is threaded onto one end of the valve stem 502. The two sides of the valve core 503 are respectively sealed to one end of the first sealing element 2 and the second sealing element 3. A rubber ring 504 is sealed between the outer surface of the valve stem 502 and the inner wall of the threaded cylinder 501. A fixing cylinder 505 is threaded onto the outer surface of the threaded cylinder 501. A bolt 4, with one end penetrating and extending into the threaded cylinder, is threaded onto the outer surface of the fixing cylinder 505. The valve body 1 is threaded with a first sealing element 2 and a second sealing element 3 on both sides of the valve body 1, and fixed with a fixing bolt 506 inside the valve body 1. The first sealing element 2 and the second sealing element 3 are fixed by the sealing bolt 4 to prevent them from loosening. The valve stem 502 is installed by the threaded cylinder 501. The valve stem 502 is rotated and sealed with the threaded cylinder 501 by a rubber ring 504 to prevent water vapor from seeping out between the threaded cylinder 501 and the valve stem 502. The valve stem 502 can drive the valve core 503 to rotate, thereby controlling the opening and closing of the ball valve. The first sealing element 2 and the second sealing element 3 prevent water vapor from seeping out from both sides of the valve core 503. The valve stem 502 is limited by the fixing cylinder 505 to prevent the valve stem 502 from loosening with the valve core 503. The fixing bolt 506 prevents the fixing cylinder 505 and the threaded cylinder 501 from loosening.

[0030] like Figures 2-4As shown, the mounting mechanism 5 has a connecting mechanism 6 inside. The connecting mechanism 6 includes a cylindrical spring 601 sleeved on the top of the valve stem 502. The top of the cylindrical spring 601 abuts against a rotating seat 602. A connecting block 603 is fixedly installed on the top of the rotating seat 602. A block sleeve 604 is fitted onto the outer surface of the connecting block 603. A sleeve bolt 605 with one end penetrating and extending into the connecting block 603 is installed on the external thread of the block sleeve 604. A ball valve handle 606 is fixedly installed on the outside of the block sleeve 604. A first impeller 607 is fixedly installed on one end of the rotating seat 602. The top of the valve stem 502... A second impeller 608 is fixedly installed at one end. A cylindrical spring 601 drives the rotating seat 602 and the connecting block 603 to maintain an upward extension posture. The top of the rotating seat 602 is limited by the fixed cylinder 505. The sleeve bolt 605 fixes the block sleeve 604 and the connecting block 603, so that the ball valve handle 606 can drive the rotating seat 602 to rotate and rise. By rotating and pressing down the ball valve handle 606, the rotating seat 602 and the first impeller 607 move downward to connect with the second impeller 608 of the valve stem 502. Then, the rotating seat 602 drives the valve stem 502 and the valve core 503 to rotate.

[0031] In use, this utility model rotates the ball valve handle 606, causing the rotating seat 602 and the first impeller 607 to move downwards and connect with the second impeller 608 of the valve stem 502. The rotating seat 602 then drives the valve stem 502 and valve core 503 to rotate, controlling the opening and closing of the ball valve. When disassembling the ball valve, unscrewing the sealing bolt 4 allows for the disassembly and assembly of the first sealing element 2 and the second sealing element 3. Unscrewing the sleeve bolt 605 allows for the separation of the square sleeve 604 and the connecting block 603, thereby removing the ball valve handle 606. Unscrewing the fixing bolt 506 allows for the separation of the fixing cylinder 505 and the threaded cylinder 501. The rotating seat 602, valve stem 502, and valve core 503 can then be disassembled and assembled sequentially, facilitating quick and accurate positioning by maintenance personnel and allowing for individual upgrades or replacements of each component.
