Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

example 1:

referring to figures 1-4: in the embodiment, a gate valve that facilitates use, including gate valve main part 1 and valve gap 2, the both sides of gate valve main part 1 link to each other with flange 8 is fixed, the internally mounted of gate valve main part 1 has valve rod 5, the top of valve gap 2 links to each other with support 6 is fixed, support 6's inside rotates with plectane 7 and links to each other, plectane 7's top is equipped with transfers adjusting device 4, the handle of current gate valve is fixed with the valve rod of gate valve, and handle and valve rod all the time be the vertically, however with the gate valve with be in the comparatively narrow and small external pipeline in space after being linked together, because the headspace of handle is less, the user passes through opening and close of handle control gate valve, lead to user's both hands to stretch comparatively hard when the handle rotates, thereby it is comparatively inconvenient to cause opening and close of gate valve.

Adjusting device 4 includes curved sliding rod 4a1, curved sliding rod 4a 1's bottom links to each other with plectane 7 is fixed, curved sliding rod 4a 1's spout links to each other with curved sliding block 4a6 slides, curved sliding block 4a 6's inner wall rotates with montant 4a3 and links to each other, montant 4a 3's bottom rotates with universal joint 4a4 and links to each other, universal joint 4a 4's front and back both ends rotate with round bar 4a5 and link to each other, curved sliding block 4a 6's left side links to each other with stop screw 4a2 screw thread, montant 4a 3's top processing has the handle, the person of facilitating the use rotates montant 4a3 through the handle, stop screw 4a 2's top processing has the handle convenient to use person to rotate stop screw 4a2 through the handle, stop screw 4a 2's bottom closely laminates with curved sliding rod 4a1, montant 4a3 drives universal joint 4a4 and rotates, montant 4a3 drives curved sliding block 4a6 and slides along curved sliding rod 4a 1's spout, round bar 4a 5's outer wall rotates with valve gap 2, the bottom of valve rod is connected through the many plug-in succession of bolt of valve rod 5 top.

The working principle is as follows:

when the convenient gate valve is used, a user is communicated with pipelines on two sides of the outside through flanges 8 on two sides, then the user rotates a limiting screw rod 4a2, the limiting screw rod 4a2 moves upwards along an arc-shaped sliding block 4a6, the limiting screw rod 4a2 drives an arc-shaped sliding rod 4a1 to be removed from the joint, then a vertical rod 4a3 is pulled, the vertical rod 4a3 drives a universal joint 4a4 to rotate along a round rod 4a5, meanwhile, the vertical rod 4a3 drives the arc-shaped sliding block 4a6 to interact along a sliding groove of the arc-shaped sliding rod 4a1, and then the limiting screw rod 4a2 is rotated reversely, so that the limiting screw rod 4a2 is tightly jointed with the arc-shaped sliding rod 4a1, and the angle of the vertical rod 4a2 is transversely adjusted;

the vertical rod 4a2 is reset, then the circular plate 7 is rotated for ninety degrees, then the vertical rod 4a2 is pulled, and the vertical rod 4a2 rotates along the universal joint 4a4, so that the front and back angle directions of the vertical rod 4a2 are adjusted;

then rotate montant 4a3, montant 4a3 drives reverse section 4a4 and rotates, and universal joint 4a4 drives round bar 4a5 and rotates, and round bar 4a5 drives valve rod 5 and rotates, and valve rod 5 drives the flashboard removal in the gate valve to open and close the gate valve, and then realize opening and close through the drive gate valve of different angles, make the gate valve use more convenient.
