Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-3, a false operation prevention non-rising stem soft seal gate valve with a flange plate comprises a gate valve body 1, a valve cover 4 disposed above the gate valve body 1, a water inlet channel 2 and a water outlet channel 3 radially disposed along the gate valve body 1, and a valve plate 5 disposed between the water inlet channel 2 and the water outlet channel 3 for controlling opening and closing of fluid, wherein a valve rod 6 is disposed above the valve plate 5 and inside the gate valve body 1, a channel is disposed above the valve rod 6, an upper end of the valve rod 6 penetrates out of the channel, the valve plate 5 is disposed on the valve rod 6, two first channels 16 are symmetrically disposed on the valve rod 6, a second channel 18 connected with the first channels 16 is disposed on the valve cover 4, a toothed bar 15 is slidably disposed in the second channel 18, one end of the toothed bar 15 can slide into the first channel 16, and a tooth socket is disposed at the other end, rotatable be equipped with in the second passageway 18 with tooth's socket toothing's gear 14, be equipped with on the valve gap 4 and be used for the drive 14 pivoted dwang 11 of gear, third passageway 9 has been seted up to valve gap 4, the fixed block 10 that is equipped with in third passageway 9 inner wall, dwang 11 one end is rotatable to be located on the fixed block 10, the dwang 11 other end and gear 14 fixed connection, be equipped with in the third passageway 9 and be used for the drive dwang 11 pivoted drive arrangement, drive arrangement is worm wheel 12 and worm 13, the fixed cover of worm wheel 12 is located on the dwang 11, worm 13 is rotatable to be located in the valve gap 4, valve gap 4 is worn out to worm 13 one end and is linked together with the outside, worm wheel 12 and the meshing transmission of worm 13.

In order to prevent others from rotating the worm 13 and conveniently rotate the worm 13, the worm 13 is flush with the valve cover 4, and a rotating groove 17 for an external tool to be clamped in is formed in the worm 13.

In order to conveniently rotate the hand wheel 8, the hand wheel 8 is fixedly arranged on the valve rod 6.

In order to facilitate connection of the gate valve and an external pipeline, the two ends of the gate valve body 1, which are positioned at the water inlet channel 2 and the water outlet channel 3, are fixedly provided with hand wheel 8 flange plates 7.

The working principle is as follows:

when the gate valve is to be closed, the valve rod 6 is rotated, the valve rod drives the valve plate 5 to close the gate valve, the valve plate is clamped into the rotating groove 17 through an external tool, then the worm 13 is rotated, the worm 13 drives the worm wheel 12 to rotate, the worm wheel 12 drives the rotating rod 11 to rotate, the rotating rod 11 drives the gear 14 to rotate, the gear 14 is in meshing transmission with a tooth groove on the toothed rod 15, the toothed rod 15 is driven to slide in the second channel 18 and slide into the first channel 16 to be clamped with the valve rod 6, and the gate valve is locked.
