Abstract
The invention discloses a directly linked straight-travel electric actuating mechanism, which is simple in structure and is convenient to mount. The mechanism consists of a motor (1), a worm (2), a worn wheel (3), a hollow shaft (4), a slide block (5), a guide post (6), a flange disc (7), a button (8), a box body (9), a valve rod nut (10), a flange disc (11), a valve rod (12) and a valve (13), and is characterized in that: the valve rod nut (10) and the valve rod (12) are directly mounted together; a screw thread structure is arranged inside the hollow shaft (4), the screw thread structure is meshed with screw threads on the outer part of the slide block (5); one end of the guide post (6) is embedded in a guide groove of the slide block (5) and is connected with the slide block (5); and the other end of the guide post (6) is connected with the flange disc (11). The mechanism and the valve (13) can be directly mounted together without parts, such as a bracket, a coupling shaft sleeve with screw threads, a screw rod nut and the like, and complex adjustment processes; and the mechanism is simpler in structure and more attractive in appearance.
Description
Technical field
The present invention relates to a kind of electric actuator, relate in particular to a kind of straight connection type straight stroke electric actuating mechanism.
Background technique
In the existing technology; Straight stroke electric actuating mechanism generally can't directly connect with valve; Support that must be through a special use with the flange plate of the flange plate of electric actuator and valve be linked together, also need one the scyewed joint cover with the valve rod of the take-off lever of electric actuator and valve be linked together, not only complex structure, adjust loaded down with trivial details; And cost is higher, outward appearance is ugly, the more important thing is easily and is out of order.
Summary of the invention
In order to solve above technical problem; The present invention provides a kind of features simple structure, the convenient straight connection type straight stroke electric actuating mechanism of installing; Constitute by motor (1), worm screw (2), worm gear (3), hollow shaft (4), slide block (5), directional post (6), flange plate (7), key (8), casing (9), Stem Mut (10), flange plate (11), valve rod (12), valve (13), it is characterized in that Stem Mut directly and valve rod be installed together; On slide block, be provided with aperture and guiding groove, the outside is provided with screw thread, and valve rod passes aperture and is connected with slide block; Hollow shaft inside is provided with worm structure, the thread engagement outside with slide block; Directional post one end embeds in the guiding groove of slide block, is connected with slide block, and the other end is connected with flange plate.
Beneficial effect of the present invention is: the present invention can be directly installed on valve, need support, component such as threaded connection axle sleeve, feed screw nut, do not need loaded down with trivial details adjustment link yet, and structure is simpler, and is also more attractive in appearance.

Fig. 3 is a sectional view of the present invention;
Fig. 4 is an exploded view of the present invention;
Fig. 5 is a major part connection diagram of the present invention.
Embodiment
To shown in Figure 5, when motor (1) drove hollow shaft (4) rotation through worm screw (2), worm gear (3), key (8), through thread engagement, slide block (5) can be done straight line motion along directional post (6), because the effect of directional post (6) has limited the rotation of slide block (5) according to Fig. 1.Because the valve rod (12) of valve (13) is installed together with slide block (5), do straight line motion so just driven valve rod (12), reached the function of opening/shutting valve.
Because the two ends of directional post (6) are fixing by flange plate (7), therefore, slide block (5) can only and can not rotate along directional post (6) slip.
Above-mentioned worm screw (2), worm gear (3), hollow shaft (4), slide block (5), directional post (6), flange plate (7), key parts such as (8) are installed in the casing (9), and motor (1) also is installed on the casing (9), has constituted the straight connection type straight stroke electric actuating mechanism.
When valve connected with actuator, as transition piece, its valve flanges dish (11) was directly installed on the flange plate (7) of actuator without any need for support and axle sleeve; Valve rod (12) extend in the actuator, directly fixes getting final product with slide block (5) with Stem Mut (10).
Slide block (5) is a critical piece of the present invention, and middle shoulder hole is used for connecting the valve rod (12) of valve; Outside screw thread and the engagement of the internal thread of hollow shaft (4) also have two pilot holes in the both sides of shoulder hole, are used to penetrate directional post.
Hollow shaft (4) also is a critical piece of the present invention, the thread engagement that its internal thread and slide block (5) are outside, and when hollow shaft (4) rotated, driving sliding block (5) was done straight line motion; Directional post (6) passes from the pilot hole of slide block (5), and two epicranium flange plate are fixed, and directional post (6) has limited the rotation of slide block (5), makes slide block (5) do straight line motion along axis.
Flange plate (7) is used to connect the flange plate (11) of valve, and is used for fixing directional post (6).
Claims (4)
1. straight connection type straight stroke electric actuating mechanism; Constitute by motor (1), worm screw (2), worm gear (3), hollow shaft (4), slide block (5), directional post (6), flange plate (7), key (8), casing (9), Stem Mut (10), flange plate (11), valve rod (12), valve (13), it is characterized in that Stem Mut (10) directly and valve rod (12) be installed together.
2. according to the described straight connection type straight stroke electric actuating mechanism of claim 1, it is characterized in that on slide block (5), being provided with aperture and guiding groove, the outside is provided with screw thread, and valve rod (12) passes aperture and is connected with slide block (5).
3. according to the described straight connection type straight stroke electric actuating mechanism of claim 1, it is characterized in that hollow shaft (4) inside is provided with worm structure, the thread engagement outside with slide block (5).
4. according to the described straight connection type straight stroke electric actuating mechanism of claim 1, it is characterized in that directional post (6) one ends embed in the guiding groove of slide block (5), be connected that the other end is connected with flange plate (11) with slide block (5).
