The self-propelled electric gate valve can realize quick opening/closing, is reasonable and simple in structure and avoids material waste; meanwhile, the stability of equipment is improved, the wear and the maintenance cost of parts of the equipment are reduced and the self-propelled electric gate valve has high practicability.
Description
Technical field
The utility model belongs to gate valve technical field, particularly a kind of Self walking electric gate valve.
Background technique
Gate valve is one of the most frequently used block valve, is mainly used to connect or block the medium in pipeline, and the pressure of utilization, temperature and diameter range are very large, in especially applying to, large diameter pipeline.Traditional gate valve complex structure, valve body is huge, consumptive material is more, difficult in maintenance.
Model utility content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Self walking electric gate valve, has simplified the structure of gate valve, makes its opening and closing that can not only realize valve, and improved the stability of equipment operation.
Technological scheme: in order to realize above-mentioned model utility object, the technological scheme that the utility model adopts is:
A Self walking electric gate valve, comprises upper bracket, lower valve body, valve plate, running shaft and reducing motor, and described running shaft is arranged on valve plate by bearing spider, and running shaft is driven by reducing motor; Two ends at described running shaft are equipped with gear; On described upper bracket, be provided with upright guide rail, on upright guide rail, be provided with the tooth bar that mate gear is used; Outside at described gear and tooth bar is equipped with link plate; One end of described link plate is sleeved on running shaft, and the other end is provided with roller, and roller is along the inner slide of upright guide rail; The cross section of described upright guide rail is I shape.
On described lower valve body, be provided with the outer upper saw pulley that coordinates valve plate to slide up and down.
In the both sides of described valve plate, be equipped with side upper saw pulley.
Described reducing motor is connected with running shaft by sprocket wheel.
On described running shaft, be provided with the bearing and the axle sleeve that are used in conjunction with.
Between described lower valve body and valve plate, be provided with seal arrangement.
Beneficial effect: compared with prior art, Self walking electric gate valve of the present utility model can not only be realized the fast opening and closing of valve, and rational in infrastructure simple, avoided the waste of material; Meanwhile, improve the stability of equipment, reduced loss and the maintenance cost of equipment component, there is good economic benefit, there is good practicability.

Fig. 1 is the plan view of Self walking electric gate valve;
Fig. 2 is the side view of Self walking electric gate valve;
Fig. 3 is that Self walking electric gate valve A-A is to view.
Embodiment
Below by specific embodiment, the utility model is further illustrated; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, Self walking electric gate valve comprises upper bracket 1, lower valve body 2, valve plate 3, running shaft 5 and reducing motor 4, and running shaft 5 is arranged on valve plate 3 by bearing spider 6, and running shaft 5 is driven by reducing motor 4; At the two ends of running shaft 5, be equipped with gear 7; On upper bracket 1, be provided with upright guide rail 10, on upright guide rail 10, be provided with the tooth bar 8 that mate gear 7 is used; Outside at gear 7 and tooth bar 8 is equipped with link plate 17, and one end of this link plate 17 is sleeved on running shaft 5, and the other end is provided with roller 9, and this roller 9 is along the inner slide of upright guide rail 10; On lower valve body 2, be provided with the outer upper saw pulley 11 that coordinates valve plate 3 to slide up and down; In valve plate 3 both sides, be equipped with side upper saw pulley 12; Reducing motor 4 is connected with running shaft 5 by sprocket wheel 13; On running shaft 5, be provided with the bearing 14 and the axle sleeve 15 that are used in conjunction with; Between lower valve body 2 and valve plate 3, be provided with seal arrangement 16; Wherein, the cross section of upright guide rail 10 is I shape.
Working procedure: start reducing motor 4, by sprocket wheel 13 driven rotary axles 5 rotations, and then the gear 7 at driven rotary axle 5 two ends rotates along tooth bar 8, and then valve plate 3 upward slidings that are connected with running shaft 5 of drive; During this time, export-oriented guide wheel 11 slides along valve plate 3, reduces friction; Side guide wheel 12, along upper bracket 1 upward sliding, reduces friction; Meanwhile, the roller 9 of link plate 17, along the inner slide of upright guide rail 10, has further improved the efficiency of valve opening, has reduced friction; The radial forces that produce due to, gear 7, tooth bar 8 with the roller 9 of link plate 17, the power of upright guide rail 10 generations is a pair of internal force, equal and opposite in direction, opposite direction, cancels out each other, and has reduced the distortion that tooth bar 8, upright guide rail 10 etc. cause because of radial force; When reducing motor 4 reversion, by that analogy, valve plate 3 slides and with lower valve body 2 contacts downwards, and seal by seal arrangement 16.
This Self walking electric gate valve can not only be realized the fast opening and closing of valve, and rational in infrastructure simple, has avoided the waste of material; Meanwhile, improve the stability of equipment, reduced loss and the maintenance cost of equipment component, there is good economic benefit, there is good practicability.
