Abstract
The utility model provides an executive mechanism of unloading-air lock valve, comprising a valve body, a drive unit, a push rod, a crank, a joint pin, a gravity hammer, a connecting rod and a valve head, etc. The utility model is characterized in that the push rod is connected with the crank through mobile connection to obtain a relative displacement distance between the crank and the push rod, thereby preventing damage on the drive unit or the executive mechanism caused by untight close or blockage by bulk material of the valve head due to connecting rod deformation; moreover, adopting the executive mechanism can realize reduction in maintenance and convenient replacement and is easy to adopt automatic control; meanwhile, the utility mode alarms in time when problem occurs so as to reduce losses.
Description
Affiliated field
The utility model belongs to a kind of discharging---blocking valve, specifically is discharging---the actuating unit on the blocking valve.
Background technology
It is that form with hinges is connected that the actuating unit of existing discharging---blocking valve has plenty of its push rod and crank, closing and opening by the length location valve head of adjusting push rod.Because the distortion of push rod miles of relative movement sum of errors valve head connecting rod often is to be not closed completely to cause the wearing and tearing of leaking out with valve head.
Summary of the invention
The purpose of this utility model is exactly---problem that the actuating unit of blocking valve exists provides a kind of discharging---actuating unit of blocking valve at existing discharging.
The purpose of this utility model is achieved in that it is made up of valve body, actuating device, push rod, crank, attachment pegs, weight, connecting rod, valve head, is characterized in: adopt mobile width of cloth type of attachment between push rod and the crank.
Concrete structure of the present utility model has: be equipped with chute on its push rod, pacify attachment pegs on the crank, and therewith be contained in the chute of push rod, constitute the mobile width of cloth.
Concrete structure of the present utility model also has: be equipped with chute on its crank, pacify attachment pegs on the push rod, and therewith be contained in the chute of crank, constitute the mobile width of cloth.
Characteristics of the present utility model are to adopt between push rod and the crank mobile width of cloth connection mode, make the motion between crank and the push rod that one section relative movement distance be arranged, can stop because rod deformation is directed at that valve head is not closed completely or valve head causes the damage of actuating device or actuating unit when being blocked by bulk materials.Adopt this device that its maintenance is reduced, it is convenient to change, and is easy to adopt automatic control means, can in time report to the police when going wrong, and reduces the loss.
Description of drawings
Accompanying drawing 1 is an integral structure scheme drawing of the present utility model.
Accompanying drawing 2 for for the A of accompanying drawing 1 to view.
Accompanying drawing 3 is the partial enlarged drawing of push rod and crank pins junction.
Accompanying drawing 4 be the another kind of mode in push rod attachment pegs and crank connecting link place partial enlarged drawing.
The specific embodiment
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is elaborated.
As shown in Figure 1, 2: the utility model is made up of valve body 3, actuating device 1, push rod 2, crank 5, attachment pegs 9, weight 4, connecting rod 8, valve head 7 etc., be characterized in: adopt mobile width of cloth type of attachment between push rod 2 and the crank 5, attachment pegs 9 moves freely distance in chute.
As shown in Figure 3, the specific embodiment of the present utility model has: be equipped with chute 21 on its push rod 2, peace attachment pegs 9 and therewith being contained in the chute 21 of push rod 2 on the crank 5 constitutes the mobile width of cloth, the attachment pegs 9 on the crank 5 chute 21 in about movably apart from being respectively D and H.
As shown in Figure 4, the specific embodiment of the present utility model also has: be equipped with chute 51 on its crank 5, peace attachment pegs 9 also therewith is contained in the chute 51 of crank 5 on the push rod 2, constitute the mobile width of cloth, attachment pegs 9 on the push rod 2 in chute 51 about movably distance be respectively H and D, see Fig. 3, Fig. 4, its D act as, when the push rod shift length changes or rod deformation, and push rod has put in place to left movement, this moment, valve head was not also closed tight, can under the effect of weight valve head locking be closed tight; The effect of H is to meet the material of bulk to be stuck between valve head and the valve body when closing, this moment push rod 2 since the effect of limit device 10 continues direction motion left put in place till, so the effect of distance H is the damage that prevents to cause when card from having bulk materials equipment such as actuating device or actuating unit.
Concrete working process of the present utility model is such, when push rod 2 moved right under the effect of actuating device 1, driving crank 5 was that circular motion is done in the center of circle with axle 6, because valve head 7 is fixed on the axle 6 by connecting rod 8, valve head moves downward and is opened, and material flows out downwards; When push rod 2 under the effect of actuating device 1 during to left movement, under the effect of the weight and the mobile width of cloth, the valve head upward movement to closing, stops the outflow of material.
