Abstract
The invention discloses an air cylinder lifting type valve with safer use in a bag-type dust remover, which comprises an air cylinder. The air cylinder is fixedly arranged on a fixed bracket in the dust remover. The air cylinder is connected with an electromagnetic valve through a compressed air inlet pipe. A piston rod of the air cylinder penetrates through an installation hole on the fixed bracket to extend out. A cover plate is fixedly arranged at the end part of the piston rod. The cover plate is matched with a ventilation opening of the dust remover. A press plate is fixedly arranged on the piston rod. A spring is sleeved on the piston rod, one end is connected with the press plate, and the other end is connected with the fixed bracket. The elastic force direction of the spring is consistent with the direction of the piston rod and the cover plate leaving the air outlet of the dust remover. The invention has the advantages of no automatic closing under the condition of air cutoff of the air cylinder, simple structure and safe and reliable use.
Description
Technical field
The present invention relates to a kind of sack cleaner, relate in particular to a kind of air cylinder lifting formula valve that is used in the sack cleaner.
Background technology
At present; On the blow vent of sack cleaner, all can use air cylinder lifting formula valve; Existing air cylinder lifting formula valve comprises: be fixedly installed on the cylinder on the fixed support in the deduster, cylinder is connected with magnetic valve through compressed air inlet pipe, and the installing hole that the piston rod of cylinder passes on the deduster fixed head stretches out; End at piston rod is set with cover plate, and cover plate and deduster blow vent cooperatively interact.When the air cylinder lifting formula valve of this structure used, the action of control magnetic valve fed compressed air through compressed air inlet pipe in cylinder; Make the piston rod of cylinder drive the cover plate up-down; Realization being opened and closing the deduster blow vent, if but under the situation that cylinder is died, piston rod and cover plate can fall under the effect of self gravitation automatically; The deduster blow vent is closed easy like this having an accident.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of use safer be used in the air cylinder lifting formula valve in the sack cleaner.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is: be used in the air cylinder lifting formula valve in the sack cleaner, comprise: be fixedly installed on the cylinder on the fixed support in the deduster, cylinder is connected with magnetic valve through compressed air inlet pipe; The installing hole that the piston rod of cylinder passes on the fixed support stretches out; End at piston rod is set with cover plate, and cover plate and deduster blow vent cooperatively interact, and on described piston rod, also is set with pressing plate; On piston rod, also be arranged with spring; One end of spring is connected with pressing plate, and the other end of spring is connected with fixed support, and the elastic force direction of spring is consistent with the direction that piston rod and cover plate leave the deduster gas outlet.
In order to solve above-mentioned further technical problem better, further technical scheme of the present invention is: described magnetic valve is a two-position-five-way solenoid valve.
Advantage of the present invention is: the air cylinder lifting formula valve that is used in the sack cleaner of said structure can not closed under the situation that cylinder is died automatically, and is simple in structure, safe and reliable.
Description of drawings
Fig. 1 is used in the structural representation of the air cylinder lifting formula valve in the sack cleaner for the present invention.
Among the figure: 1, fixed support, 2, cylinder, 3, compressed air inlet pipe, 4, magnetic valve, 5, piston rod, 6, cover plate, 7, the deduster blow vent, 8, pressing plate, 9, spring.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1; Be used in the air cylinder lifting formula valve in the sack cleaner, comprise: be fixedly installed on the cylinder 2 on the fixed support 1 in the deduster, cylinder 2 is connected with magnetic valve 4 through compressed air inlet pipe 3; In the present embodiment, described magnetic valve 4 is a two-position-five-way solenoid valve.The installing hole that the piston rod 5 of cylinder 2 passes on the fixed support 1 stretches out; Be set with cover plate 6 in the end of piston rod 5, cover plate 6 cooperatively interacts with deduster blow vent 7, on piston rod 5, also is set with pressing plate 8; On piston rod 5, also be arranged with spring 9; One end of spring 9 is connected with pressing plate 8, and the other end of spring 9 is connected with fixed support 1, and the elastic force direction of spring 9 is consistent with the direction that piston rod 5 and cover plate 6 leave deduster gas outlet 7.
During being used in air cylinder lifting formula valve in the sack cleaner and using of said structure; 4 actions of control magnetic valve; In cylinder 2, feed compressed air through compressed air inlet pipe 3, make the piston rod 5 of cylinder 2 drive cover plate 6 up-downs, realize opening and closing deduster blow vent 7.In the process that piston rod 5 descends, can spring 9 be depressed, the process medi-spring 9 that rises at piston rod 5 also can and then extend.Under the situation of dying when cylinder 2, spring 9 will prevent that its situation of deduster blow vent 7 being closed automatically because of gravity falls from taking place with piston rod 5 and cover plate 6 jack-up upwards.
