Description

New-type gate valve

Technical field

The utility model relates to a kind of valve, especially a kind of new-type gate valve.

Background technique

Gate valve is an opening and closing element spool, and the direction of motion of spool is vertical with flow direction, and traditionally gate valve is due to transport The reason of fluid media (medium), will cause gate valve pivot region there is a situation where getting rusty, to cause artificially to be difficult to the case where opening hair It is raw, sometimes, need to carry out using tool to agitate and can open reluctantly, when emergency occurs, the small and weak old man of body, Child and women are difficult to open the valve of help, and such case is quite dangerous, can not in time, quickly open and get rusty The valve of state will cause property loss and will cause the problem of human life can not ensure safely.

Utility model content

The utility model will solve the disadvantage that the above-mentioned prior art, provide it is a kind of can easily, facilitate the new-type of opening and closing Gate valve, meeting in case of emergency being capable of quick, easily Open valve demand.

The utility model solves the technical solution of its technical problem use: this various new-type gate valve, including valve body, on valve body It is provided with runner, the spool for opening and closing runner is longitudinally plugged on valve body, the top of spool is fixed with mast, and top end of the valve body is fixed There is pedestal, pedestal is equipped with the driving mechanism that mast can be driven to move up and down；Driving mechanism includes the cavity opened on the base, chamber It being equipped in vivo and is fixed on the transverse slat on mast top, the arranged on left and right sides of mast is designed with the first threaded rod at cavity, and two the The top and bottom end of one threaded rod are all fixed with the round bar with the coaxial arrangement of the first threaded rod, and the cross section of bottom end round bar is less than the The cross section size of one threaded rod is equipped with the thrust bearing that a pair is located at below the round bar of bottom end, two thrust bearings at cavity Lower circle be fixed at pedestal, the upper circle of two thrust bearings can rotate, and the cover board of airtight cavity, two tops are fixed on pedestal The first rolling bearing units being fixed at cover board are respectively equipped with above round bar, two bottom end round bars are respectively fitting into inserting for thrust bearing At hole and place the bottom surface of two first threaded rods respectively on the upper circle of two thrust bearings, two top round bars are separately mounted to two At first rolling bearing units, two first threaded rods are threaded at transverse slat respectively, are all fixed on the arranged on left and right sides wall of cavity vertical The straight guide being arranged to length, the arranged on left and right sides of transverse slat are all fixed with the first sliding block being slidably connected on straight guide, two tops Large straight gear is all fixed on round bar, all gears are engaged with small Spur gear between two large straight gears, and the second band is fixed on cover board Seat bearing, is equipped with shaft on the second rolling bearing units, the top of shaft is fixed with turntable, and the bottom end of shaft is fixed on small Spur gear Center at.Here the effect of driving mechanism is, can labour-saving transverse slat drive up and down, so as to labour-saving drive Spool moves up and down；Here the effect of large straight gear, small Spur gear is large straight gear can be driven to rotate using small Spur gear, To drive the rotation of the first threaded rod, and then sufficiently large torque can be generated using small Spur gear and is moved up and down come band motion plate It is dynamic；Here the effect of straight guide, the second sliding block is the resistance that can reduce when transverse slat moves up and down, so as to more easily Band motion plate move up and down；Here the effect of thrust bearing, the first rolling bearing units is when can reduce the rotation of the first threaded rod Rotary resistance, so as to more easily band motion plate move up and down；Here the biography between small Spur gear and large straight gear Dynamic ratio is more than or equal to 3:1, so as to just be able to drive turntable using the power of very little, even if the pivot region of valve is given birth to Rust, also can easily be opened；When in use, lubricating oil can be injected in cavity, it can antirust can also increase lubricity, So that turntable is rotated more laborsaving, and then more labor-saving strap movable valve plug is moved up and down；This driving mechanism can also be to prevent Only spool is pressurized excessive the case where moving up, since transverse slat drives mobile form using double first threaded rods, so valve is being closed Even if when state, fluid medium pressure it is very big, will not make transverse slat compression move up, so that the utility model is able to use in pressure In very big fluid media (medium) conveying.

Further perfect, the top of pedestal is fixed with arc guide rail, and the arranged on left and right sides of shaft, which is designed with, to be fixed on turntable Vertical bar, the bottom end of two vertical bars, which is all fixed with, cooperates the second sliding block at arc guide rail.Here arc guide rail, vertical bar, second The effect of sliding block is, it can be ensured that turntable stress is more uniform, more light when rotating turntable, mitigates suffered by shaft Bending force, and the rotation of turntable can be facilitated, reduce the abrasion of shaft.

It is further perfect, one group of radial screw channel being uniformly arranged along center of turntable is provided on the outer surface of turntable Hole is all threaded with the second threaded rod on each radial direction screw channel hole, and the outer end of each second threaded rod, which is all fixed with, turns block. Here radial screw channel hole, the second threaded rod, the effect for turning block is, for increasing torque, so as to more easily turn Turn disk, getting rusty for tanacity can be such that gate valve is easily opened and closed again in time.

The utility model has the advantages that: the utility model smart structural design, rationally, can be saved using driving mechanism Power drive up and down to transverse slat, moves up and down so as to labour-saving band movable valve plug；Utilize large straight gear, small Spur gear Large straight gear can be driven to rotate using small Spur gear, to drive the rotation of the first threaded rod, and then utilize small Spur gear energy Sufficiently large torque is enough generated to move up and down with motion plate；It can reduce transverse slat using straight guide, the second sliding block and move up and down When resistance, so as to more easily band motion plate move up and down；It can reduce using thrust bearing, the first rolling bearing units Rotary resistance when first threaded rod rotates is moved up and down so as to more easily band motion plate, is worthy of popularization.
