Description
Technical field
The present invention relates to valve connection bracket technical field, be specifically related to a kind of single straight journey support.
Background technique
In prior art, straight stroke electric actuating mechanism generally directly cannot be connected with valve, by a special support, the lower flange face of electric actuator and the flanged surface of valve must be linked together, also need the take-off lever of electric actuator and the valve rod of 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 use in various rugged environment for a long time, due to reasons such as acid etching oxidations, be very easy to occur all kinds of fault, the work that affects is produced.
Summary of the invention
Goal of the invention of the present invention is the shortcoming in order to overcome above-mentioned background technology, provides a kind of more stable, safety and life-span longer straight journey support.
Technological scheme of the present invention 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 connect end cap be connected with valve rod and be fixed on craspedodrome masthead end, main shaft and driving casing are connected by left-handed trapezoidal thread and are fixed on sleeve inner by flat key, sleeve inner has long keyway, craspedodrome bar assembly can only be moved up and down along keyway, realize the opening and closing of valve, connect between described driving casing and main shaft for being threaded, this screw thread is the left-handed trapezoidal thread adopting American standard.
Described driving casing material is copper, and driving casing cylindrical has screw thread, and it is inner that described driving casing is fixed on craspedodrome bar 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 to be arranged on main shaft and to be fixed with jackscrew, make can not produce during main axis to move axially.
The material of described upper flange, lower flange, sleeve is 1Cr18Ni9.
The invention has the beneficial effects as follows: electric actuator can be connected with valve by the present invention, owing to adopting lead screw transmission, so walking process is very steady, noiseless, vibrations; The connection places such as sleeve of the present invention and flange, craspedodrome bar and gland all adopt O type circle to seal, can water proof and dust proof effectively, prevent the various cavitation erosions of working site, acid etching, significantly promote 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.

Embodiment
The present embodiment is a kind of straight journey support, comprises upper flange (3), lower flange (25), sleeve (14), drives running gear; Described straight journey cantilever tip is provided with upper flange (3), bottom is provided with lower flange (25), middle part is for driving running gear, and described driving running gear comprises driving casing (12), main shaft (7), retaining ring (19), craspedodrome bar (8), connects end cap (2); Wherein connect end cap (2) be connected with valve rod and be fixed on craspedodrome bar (8) top, main shaft (7) and driving casing (12) are connected by left-handed trapezoidal thread and are fixed on sleeve (14) inside by flat key, sleeve (14) inside has long keyway, craspedodrome bar (8) assembly can only be moved up and down along keyway, realize the opening and closing of valve, connect between described driving casing (12) and main shaft (7) for being threaded, this screw thread is the left-handed trapezoidal thread adopting American standard.
According to Fig. 1, Fig. 2, when electric actuator is rotated by the spline drive main spindle (7) on main shaft (7), pass through thread engagement, driving casing (12) has the trend of rotation, due to the effect of key (11), limit the rotation of driving casing (12), can only straight line motion be done.Because driving casing (12) and craspedodrome bar (8) connect together, due to the effect of key (11) and thrust-bearing (17), driving casing (12) and craspedodrome bar (8) do straight line motion together.
Being fixed on the driving casing briquetting (16) on main shaft (7), pressure ring (15) and thrust-bearing (17) is pressed on the step of sleeve (14), and acting in conjunction stops main shaft 7 to move vertically.Because the effect of key (9) can not relatively rotate or mobile between sleeve (14) and upper flange (3), lower flange (25).
During support installing, connect end cap (2) and valve rod connection, upper flange (3) upper-end surface and valve flanges dish connect, and electric actuator and lower flange (25) end face connect.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
