Description

Telescopic gate valve Technical Field The utility model relates to the technical field of valves, in particular to a telescopic gate valve. Background The gate valve is a shutter, the moving direction of the shutter is vertical to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. The gate valve is sealed through the contact of disk seat and flashboard, and the metal material is built up to the sealed face in order to increase the wearability generally, and the flashboard has rigid flashboard and elasticity flashboard, and according to the difference of flashboard, the gate valve falls into rigid gate valve and elasticity gate valve. Most of the existing sluice valves are fixed integrated structures, when the sluice valves between pipelines are replaced, the distance between the pipelines can be changed, so that new sluice valves are difficult to install and even cannot be installed, old sluice valves are required to be detached and replaced with new matched sluice valves, the operation process is complicated, and the construction efficiency is affected. We have therefore proposed a retractable gate valve in order to solve the problems set out above. Disclosure of utility model The utility model provides a telescopic gate valve, which solves the problems that most of the existing gate valves in the background art are of fixed integrated structures, when the gate valves among pipelines are replaced, the distance among the pipelines can be changed, so that the new gate valve is difficult or even impossible to install, the old gate valve is required to be detached and replaced with a new matched gate valve, the operation process is complicated, and the construction efficiency is affected. The utility model provides a telescopic gate valve which comprises a gate valve body and a first connecting pipe fixedly arranged on the side surface of the gate valve body, wherein a plurality of first sliding grooves are formed in the side wall of the first connecting pipe at equal intervals, convex teeth are fixedly arranged in the first sliding grooves at equal intervals, a second connecting pipe is connected to the outer wall of the first connecting pipe in a sliding mode, grooves are formed in the side wall of the second connecting pipe at equal intervals, and sliding blocks are connected in the grooves in a sliding mode. As an alternative scheme of the utility model, the side wall of the second connecting pipe is equidistantly and rotatably connected with a plurality of threaded rods, and the threaded rods are respectively and rotatably connected in the grooves. As an alternative scheme of the utility model, one end of each of the sliding blocks is provided with a latch, and the latches can be matched with the convex teeth to finish fixation. As an alternative scheme of the utility model, a plurality of sliding blocks are provided with threaded holes, and the threaded rods are in threaded connection with the sliding blocks. As an alternative scheme of the utility model, a second chute is formed in the first connecting pipe at equal intervals, and a plurality of connecting rods are connected in the second chute in a sliding manner.
