Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1-7, the utility model provides a technical solution: a safe and environment-friendly labor-saving rod gate valve is characterized in that a frame 11 is a main body for mounting and bearing various parts;

the rod 08 is a key part for regulating the rod gate valve, and the opening size of the rod gate valve can be regulated through the opening and closing degree of the rod 08, so that the material flow above is stably controlled, and the phenomenon of material arching and bridging is reduced.

The adjusting screw shaft 04 is a power control part, and the nut 02 is rotated forwards and backwards through a proper wrench, so that the opening and closing degree of the bar 08 can be adjusted through rotation of the adjusting screw shaft 04, and the opening size of the adjusting bar gate valve is further adjusted; the limiting sleeve 042 can limit the maximum opening travel of the rod 08.

The positioning pin 01, the nut 02, the bearing with a seat 03 and the screw limiting block 09 are matched, and two ends of the adjusting screw 04 are positioned on the frame 11, so that the adjusting screw 04 can only rotate around the center in a positive and negative way;

the packing seal group 10 is used for sealing and preventing materials from leaking between the bar 08 and the frame 11;

the lower cover plate 05 and the sealing gasket 07 are matched with the frame 11 for sealing, so that leakage materials are prevented from flowing to the outside, the environment is prevented from being polluted, and waste is avoided;

the upper cover plate 06, the sealing gasket 07 are matched with the frame 11 for sealing, so that leakage materials are prevented from flowing to the outside, the environment is polluted, and waste is caused, the upper cover plate 06 is made of transparent organic glass, the abrasion and the adjustment conditions of the sealing condition of the packing sealing group 10, the bar 08, the adjusting screw 04 and other parts can be conveniently observed, and timely adjustment, maintenance and repair are facilitated.

Through the rotation of the adjusting screw rod 04, the trapezoidal thread 041 drives the bar 08 to move, so that the gate valve saves much more labor than a common manual bar gate valve;

the bar 08 moves all the time inside the frame 11, and the screw 04 is adjusted by manually operating the wrench;

each rod 08 is provided with two packing seal groups 10 for strengthening sealing, and the lower cover plate 05, the upper cover plate 06 and the sealing gasket 07 are matched with the frame 11 for sealing, so that material leakage and environmental pollution can be well prevented.
