Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to an anti-mistouch ball valve. Background Art

[0002] A ball valve is a control valve widely used in pipeline systems. It controls the flow of media by rotating the ball. The ball is usually spherical with one or more channels. When the ball rotates to be parallel to the axis of the pipeline, the valve opens and the medium can flow; when the ball rotates to be perpendicular to the axis of the pipeline, the valve closes and the medium stops flowing. The ball valve has a compact design structure, small size, light weight, easy operation, good sealing performance, low flow resistance, and can be opened and closed quickly. They are suitable for a variety of media, including water, oil, gas, etc., so they are widely used in many industries such as petroleum, chemical industry, metallurgy, electricity, shipbuilding, urban water supply and drainage. The sealing surface material of the ball valve can be selected as soft seal or hard seal according to the application requirements. The soft seal ball valve is suitable for occasions with high sealing performance requirements, while the hard seal ball valve is suitable for high temperature, high pressure, and corrosive medium environments. In addition, the ball valve is also divided into a floating ball valve and a fixed ball valve. The ball of the floating ball valve is pressed tightly against the sealing ring at the outlet end under the pressure of the medium, while the ball of the fixed ball valve is supported by a bearing and keeps a certain distance from the valve seat sealing surface. There are various driving modes for ball valves, including manual, electric, pneumatic and hydraulic, to meet different operating requirements. During use, regular inspection and maintenance are the key to ensure the long-term stable operation of the ball valve.

[0003] In order to enable the current ball valve to achieve the effect of preventing accidental touch, the existing technology often directly drives the valve ball to rotate in the form of electric control, without giving the operator the opportunity to touch it. However, in the case of fluid transportation, experienced operators can even use ordinary ball valves to achieve the effect of regulating flow like a V-type ball valve under manual adjustment control. However, compared with electric control, the manual adjustment of the ball valve has an obvious risk of accidental touch, so it needs to be avoided.

[0004] Therefore, a ball valve for preventing accidental touch is proposed to solve or alleviate the above problems. Utility Model Content

An adjustable transmission component fixedly connected to the valve ball is rotatably arranged in the through hole, and a handle is fixedly connected to the upper end of the adjustable transmission component.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] A ball valve to prevent accidental touch, such as Figure 1 As shown, it includes a valve body 1, pipes fixedly connected to both ends of the valve body 1, a valve seat 4 fixedly connected to the top of the valve body 1, and a valve ball 7 rotatably connected to the valve body 1, an end of the pipe away from the valve body 1 is fixedly connected to a connecting flange 2, a through hole penetrating into the valve body 1 is provided on the top surface of the valve seat 4, an adjustable transmission assembly fixedly connected to the valve ball 7 is rotatably arranged in the through hole, and a handle 3 is fixedly connected to the upper end of the adjustable transmission assembly.

[0023] like Figure 2-4 As shown, the adjustable transmission assembly includes a connecting sleeve 12 fixedly connected to one end of the handle 3, a valve connecting pipe 8 fixedly connected to the valve ball 7 and rotatably arranged in the through hole, an inner flower rod 9, an electromagnet 5 fixedly connected to the top of the connecting sleeve 12, a button switch fixedly connected to the bottom surface of the handle 3, a sliding rheostat 6 fixedly connected to one side of the valve seat 4, and a power supply. The inner top surface of the connecting sleeve 12 is fixedly connected with an outer spline sleeve 11, the inner flower rod 9 is slidably connected in the valve connecting pipe 8, and the outer spline sleeve 11 can be slidably connected to the inner flower rod 9. The cross-section of the inner flower rod 9, the inner cross-section of the outer spline sleeve 11, and the inner cross-section of the valve connecting pipe 8 are all regular hexagons. The connecting sleeve 12 includes a tube portion rotatably connected in the through hole, and a sleeve portion fixedly connected to the upper end of the tube portion. The sleeve portion is fixedly connected to the handle 3, and the cross-sectional area of ​​the sleeve portion is larger than the cross-sectional area of ​​the through hole. The inner flower rod 9 is made of metal. The button switch, the sliding rheostat 6, the power supply, and the electromagnet 5 are coupled to form a loop.

[0024] When the utility model is actually applied, the operator only needs to hold the handle 3 and press the button switch to enable the power supply to energize the electromagnet 5. The role of the sliding resistor 6 is to adjust the current obtained by the electromagnet 5, thereby adjusting the magnetic force of the electromagnet 5.

[0025] After the electromagnet 5 generates magnetic force, it generates an upward suction force on the inner flower rod 9, causing its upper end to enter the outer spline sleeve 11. At this time, the operator turns the handle 3, and the handle 3 can drive the outer spline sleeve 11 to deflect together through the connecting sleeve 12. When the outer spline sleeve 11 rotates, it will inevitably drive the inner flower rod 9 to rotate. The inner flower rod 9 will drive the valve ball 7 to rotate in the valve body 1 through the valve connecting pipe 8 on the outer side of its lower end, so as to complete the adjustment of the valve ball 7. After the rotation is completed, once the operator releases the handle 3 and the button switch, the electromagnet 5 will lose its magnetic force, and the inner flower rod 9 will lose its magnetic force and fall downward under the action of its own weight, thereby causing the inner flower rod 9 to separate from the outer spline sleeve 11. No matter how the operator turns the handle 3, the valve ball 7 cannot be driven to rotate, thereby avoiding accidental touch.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
