Abstract
The utility model discloses an air-pressure driving device of a feed bin door, which comprises an air cylinder and a two-position four-way electromagnetic valve. A piston dividing the air cylinder into a left cavity and a right cavity is arranged in the air cylinder, a piston rod extending out of the air cylinder is arranged on one side of the piston, an air inlet of the two-position four-way electromagnetic valve is connected with an air inlet pipe, the two-position four-way electromagnetic valve is a vertical electromagnetic valve, and the left cavity and the right cavity of the air cylinder are connected with two air outlets of the two-position four-way vertical electromagnetic valve respectively by the aid of two air guiding pipes. Leftward and rightward movements of the piston in the air cylinder are controlled by the two-position four-way vertical electromagnetic valve, a valve seat is omitted during mounting, and the two air guiding pipes are directly connected with the two air outlets of the two-position four-way vertical electromagnetic valve, so that the air-pressure driving device is convenient in maintenance and lower in market price, and service cost is reduced.
Description
Technical field
The utility model belongs to the production of fodder technical field, is specifically related to a kind of feed bin door actuating device of atmospheric pressure.
Background technology
The feed bin door in production of fodder workshop generally adopts air pressure to drive and opens or close; The two-position four-way solenoid valve of existing actuating device of atmospheric pressure is board-like electromagnetic valve; Two air extractor ducts of board-like electromagnetic valve connect the ventilation flue need install a valve seat additional; Not only install and keep in repair trouble, and the board-like electromagnetic valve market price is expensive, use cost is high.
The utility model content
The utility model is in order to solve weak point of the prior art, and a kind of dismounting maintenance, feed bin door actuating device of atmospheric pressure with low cost of being easy to is provided.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: feed bin door actuating device of atmospheric pressure; Comprise cylinder and two-position four-way solenoid valve; Be provided with the piston that cylinder is divided into left cavity and right cavity in the cylinder, piston one side is provided with stretches out the outer piston rod of cylinder, and the admission port of two-position four-way solenoid valve is connected with air inlet pipe; Said two-position four-way solenoid valve is vertical electromagnetic valve, and the left cavity of said cylinder is connected with two air extractor ducts of the vertical electromagnetic valve of two-position four-way through a ventilation flue respectively with right cavity.
The sway that the utility model adopts the vertical electromagnetic valve of two-position four-way to come the control cylinder inner carrier; Not only saved valve seat when mounted; Two ventilation flues directly are connected with two air extractor ducts of the vertical electromagnetic valve of two-position four-way; Easy to maintenance, and the market price is also cheaper, thus reduced use cost.
Description of drawings
Fig. 1 is the mounting structure scheme drawing of the utility model.
The specific embodiment
As shown in Figure 1; The feed bin door actuating device of atmospheric pressure of the utility model; Comprise cylinder 1 and the vertical electromagnetic valve 2 of two-position four-way, be provided with the piston 5 that cylinder 1 is divided into left cavity 3 and right cavity 4 in the cylinder 1, piston 5 one sides are provided with the piston rod 6 that stretches out outside the cylinder 1; The admission port of the vertical electromagnetic valve 2 of two-position four-way is connected with air inlet pipe 7, and the left cavity 3 of cylinder 1 is connected with two air extractor ducts of the vertical electromagnetic valve 2 of two-position four-way with ventilation flue 9 through ventilation flue 8 respectively with right cavity 4.
When work was used, high pressure gas through the vertical electromagnetic valve of air inlet pipe 7, two-position four-way 2, ventilation flue 8 and left cavity 3, promoted piston rod 6 and stretch out cylinder 1 successively, and piston rod 6 outer ends promote door and close; When high pressure gas successively through the vertical electromagnetic valve of air inlet pipe 7, two-position four-way 2, ventilation flue 9 and right cavity 4, high pressure gas promote piston rod 6 and to cylinder 1 in, shrink, piston rod 6 outer ends spur the door unlatching.
