Description

Technical Field

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

[0002] Ball valves are a common type of valve, mainly used to control fluid flow. Their core component is a ball with a through hole. By rotating 90 degrees, the fluid passage is opened or closed. When the through hole of the ball is aligned with the pipeline, the fluid can pass freely. When the ball is rotated to be perpendicular to the pipeline, the fluid is blocked. Ball valves have advantages such as simple structure, good sealing performance, convenient operation, and long service life. They are widely used in petroleum, chemical, and water treatment fields. A combination ball valve is a valve device that combines the functions or components of multiple ball valves.

The fixed platform 2 is fixedly connected to the top of the ball valve body 1. A circular hole is opened on the top of the fixed platform 2. The rotating shaft 3 is located in the inner cavity of the circular hole. The control mechanism 4 is used to facilitate the operation of the rotating shaft 3.

[0046] The control mechanism 4 includes a rectangular hole, a lifting plate 41, a lifting block 42, a rectangular insertion hole, an outer fixing ring 43, two notches, two force-applying blocks 44, a connecting rope 45, a control panel 46, two anti-slip components, and a storage assembly. The rectangular hole is located at the top of the rotating shaft 3. The lifting plate 41 is located inside the rectangular hole. The lifting block 42 is fixedly connected to the top of the lifting plate 41. The rectangular insertion hole is located on the outer wall of the lifting block 42. The outer fixing ring 43 is fixedly connected to the top of the fixed platform 2 and serves as a shield for protection. The lifting block 42 is located inside the outer fixing ring 43. Two notches are symmetrically located on the top of the outer fixing ring 43. Two force-applying blocks 44 are symmetrically fixedly connected to the outer wall of the lifting block 42. The force-applying blocks 44 are used to facilitate the operator to apply force to drive the lifting block 42 to move vertically. The two force-applying blocks 44 are located in opposite positions. The inner cavity of the notch is notched, and one end of the connecting rope 45 is fixedly connected to the outer wall of the ball valve body 1. The connecting rope 45 is used to prevent the control plate 46 from being lost. The connecting rope 45 can be wrapped around the control plate 46 and then the control plate 46 can be stored. The control plate 46 is fixedly connected to the other end of the connecting rope 45. The control plate 46 is long and narrow. The control plate 46 can be inserted into the rectangular socket to control the combined ball valve. Two anti-detachment components are symmetrically arranged on the front and back of the lifting plate 41. The anti-detachment components are used to prevent the lifting plate 41 from completely detaching from the rectangular hole. The anti-detachment components include an anti-detachment groove and an anti-detachment slider 47. The anti-detachment groove is opened on the inner wall of the rectangular hole. The anti-detachment slider 47 is slidably sleeved in the inner cavity of the anti-detachment groove. The anti-detachment slider 47 is fixedly connected to the outer wall of the lifting plate 41. The storage component is located on the front of the ball valve body 1. The storage component is used to store the control plate 46.

[0047] The storage assembly includes a U-shaped storage plate 48, a closure member, and a limiting member. The U-shaped storage plate 48 is fixedly connected to the front of the ball valve body 1. The control plate 46 is located inside the U-shaped storage plate 48. The closure member is located outside the U-shaped storage plate 48 and is used to close the opening at the top of the U-shaped storage plate 48. The closure member includes a sealing cloth 49, a first Velcro 410, and a second Velcro 411. The sealing cloth 49 is fixedly connected to the top of the U-shaped storage plate 48. The first Velcro 410 is fixedly connected to the front of the U-shaped storage plate 48, and the second Velcro 411 is fixedly connected to the back of the sealing cloth 49. The first Velcro 410 and the second Velcro 411 have a hook side and a rough side, respectively. By sticking the first Velcro 410 and the second Velcro 411 together, the opening at the top of the U-shaped storage plate 48 can be closed. The limiting member is located at the bottom of the control panel 46. The limiting member is used to restrict the control panel 46 located inside the U-shaped storage plate 48. The limiting member includes a limiting hole and a limiting block 412. The number of limiting holes and limiting blocks 412 can be changed, but the number of the two parts is the same. The limiting hole is opened at the bottom of the inner wall of the U-shaped storage plate 48. The limiting block 412 is located in the inner cavity of the limiting hole and is fixedly connected to the bottom of the control panel 46.

[0048] Working principle of this utility model:

[0049] When operating the combined ball valve, first apply force to the sealing cloth 49 to separate the first Velcro 410 and the second Velcro 411. After the first Velcro 410 and the second Velcro 411 are completely separated, apply a vertical upward force to the control plate 46. When the insertion block 412 is completely disengaged from the insertion hole, the control plate 46 can be held in the palm of the operator's hand. Then, use two fingers of the other hand to apply force to the two force blocks 44, and the two force blocks 44 will drive the lifting block 42 to move vertically upward. When the rectangular insertion hole on the lifting block 42 is exposed, insert the control plate 46 into the rectangular insertion hole. Then, the combined ball valve can be operated using the control plate 46. After operation, simply repeat the above operation in reverse. This avoids the situation where the operator forgets to bring the switch wrench, resulting in the inability or difficulty to operate the combined ball valve, and improves the convenience of operating the combined ball valve.
