Problems solved by technology

[0003] Butterfly valves are widely used in modern pipeline transportation. However, the existing butterfly valves often have the following disadvantages during use. The existing butterfly valves often have difficulty in turning when they have not been used for a long time. Difficult to open or close. At the same time, impurities in the medium often accumulate at the bottom of the butterfly valve core, which leads to the defect that the butterfly valve is blocked and difficult to unscrew.

Embodiment 1

[0025] Example 1, reference Figure 1-3 , High-performance anti-card dead energy-saving butterfly valve, including the valve body 4 and the three flange 14 fixed to the valve body 4, the valve body 4 is provided with the spindle 6, and the top end of the main shaft 6 is fixedly connected to the rotating plate 1, The upper side of the main shaft 6 is fixedly connected to the lower pressure plate 5, and the upper side slide is slid in the outer side of the main shaft 6, and the upper pressure plate 15 and the lower pressure plate 5 are opened to each other, and the upper pressure plate 15 and the upper pressure plate 5 card 5 The block 17 is interlaced, and the top of the main shaft 6 is fixed to the rotating disk 1, and the upper pressure plate 15 and the main shaft 6 are directly connected to the upper gasket 16, and the lower pressure plate 5 and the main shaft 6 are directly connected to the lower gasket 7, the upper washer 16 and The annular structure formed by the lower washer ...

Embodiment 2

[0026] Example 2 figure 2 There is a sleeve 10 above the valve body 4, and the sleeve 10 is provided with a compression spring 2, and the sleeve 10 is fixedly connected to the first flank 3. The opening of the valve body 4 is fixed at the opening of the opening. The blue disk 8, the first flange 3 and the second flank plate 8 are fixed by the bolt, and the spindle 6 is fixedly connected, and the pressure pan 9 and the sleeve 10 are elastically connected by the compression spring 2. The compression spring 2 pushes the spindle 6, the lower pressure plate 5, and the lower washer 7 so that the lower gasket 7 is driven to increase the sealing effect while facilitating the upper gasket 7 on the gasket 7 on the gasket.

Embodiment 3

[0027] Example 3, reference image 3 The slide rail 23 is opened on the rotating disk 1, and the main shaft 6 is fixedly connected to the slider 11, and the slider 11 is opened on the side surface of the slider 11, and the slide rail 23 is slidable with the limit chute 20, and the rotating disk 1 is opened. The threaded groove 18, and the threaded groove 18 is rotated in connection with the screw 12, and the screw 12 is fixedly connected to the slot die 19, and the groove 22 is opened on the slider 11, and the groove 22 is rotated and the rotating plate 19 is rotated, rotating the disc 1 The slide 21 is opened, and the slider 13 is fixed to the slider 13, the sliding rod 13 is slid, preferably, the outer side of the screw 12 can be fixed, so that the screw 12 is rotated to drive the slider 11. And the spindle 6 offset the central axis position of the turntable disk 1, thereby increasing the power arm of the turntable disk 1.

Abstract

The invention discloses a high-performance anti-jamming energy-saving butterfly valve, which comprises a valve body and third flanges fixedly connected to both sides of the valve body. The outer side of the bottom is fixedly connected with the lower pressing plate, and the outer side of the main shaft is slidably connected with the upper pressing plate, and the sides of the upper pressing plate and the lower pressing plate are provided with locking blocks, and the locking blocks on the upper pressing plate and the lower pressing plate are staggeredly engaged. , the top end of the main shaft is fixedly connected with a rotating disc. In the present invention, the adjustable valve core mechanism is adopted to reduce the possibility of jamming between the lower gasket and the valve body, and the deflected turntable structure is adopted to increase the distance between the main shaft and the farthest point on the turntable, thereby The arm of force is increased when the main shaft is in use, so that the rotation of the main shaft is more labor-saving.

Description

Technical field [0001] The present invention belongs to the technical field of signal processing, and is specifically high performance anti-card die energy-saving butterfly valve. Background technique [0002] Butterfly valve is also called a flap valve, is a simple structurally adjusted valve, but the butterfly valve controlled by the switch-controlled butterfly valve for the low-voltage pipe medium is a disc, rotating around the spool to achieve a valve opening and closing, butterfly valve Closing is a disc-shaped butterfly plate, rotating around its own axis, thereby achieving the purpose of opening and closing or adjustment. [0003] Butterfly valves are widely used during modern pipeline transportation, but existing butterfly valves often have some shortcomings in the process of use, existing butterfly valves often often have long-term rotation difficult, card It is difficult to open or close the problem, and at the same time, the bottom of the butterfly valve blade often oc...
