In prior art, straight stroke electric actuating mechanism generally cannot directly be connected with valve, must the lower flange face of electric actuator and the flanged surface of valve be linked together by a special support, also need the valve rod of the take-off lever of electric actuator and valve be linked together a threaded connecting sleeve, not only complex structure, adjust loaded down with trivial details, and high expensive, outward appearance ugliness, cannot seal, and in various rugged environment, use for a long time, due to reasons such as acid etching oxidations, be very easy to occur all kinds of faults, the work that affects is produced.
Summary of the invention
Goal of the invention of the present utility model is the shortcoming in order to overcome above-mentioned background technology, and a kind of more stable, safety and longer straight journey support of life-span are provided.
The technical solution of the utility model is: a kind of straight journey support, comprises upper flange, lower flange, sleeve, driving running gear; Described straight journey cantilever tip is provided with upper flange, and bottom is provided with lower flange, and middle part is for driving running gear, and described driving running gear comprises driving casing, main shaft, retaining ring, craspedodrome bar, connects end cap; Wherein connecting end cap is connected with valve rod and is fixed on craspedodrome masthead end, main shaft is connected and is fixed on sleeve inner by flat key by left-handed trapezoidal thread with driving casing, sleeve inner has long keyway, the bar assembly that makes to keep straight on can only move up and down along keyway, realize the switching of valve, between described driving casing and main shaft, be connected to and be threaded, this screw thread is the left-handed trapezoidal thread that adopts standard made in U.S.A.
Described driving casing material is copper, and driving casing cylindrical has screw thread, and described driving casing is fixed on craspedodrome bar inside by screw thread.
Described driving running gear also comprises gland, limited ring, pressure ring, driving casing briquetting, thrust ball bearing; The material of described gland, limited ring, pressure ring, driving casing briquetting all adopts cast iron STSi5R, and wherein gland, limited ring, thrust ball bearing, pressure ring are arranged on main shaft and with jackscrew and are fixed, and when main shaft is rotated, can not produce and move axially.
The material of described upper flange, lower flange, sleeve is 1Cr18Ni9.
The beneficial effects of the utility model are: the utility model can be connected electric actuator with valve, owing to adopting lead screw transmission, so walking process is very steady, and noiseless, vibrations; The connection places such as the utility model sleeve and flange, craspedodrome bar and gland all adopt the sealing of O type circle, and water proof and dust proof effectively, prevents various cavitation erosions, the acid etching of working site, significantly promotes working life; Owing to all making encapsulation process everywhere, the parts such as leading screw, sleeve are hidden in inside completely, terminal with compact integral structure, attractive in appearance.
