Abstract
The utility model relates to a two-position three-way auto-control valve of a loose fiber pneumatic conveying pipe. The two-position three-way auto-control valve comprises a valve housing; an inlet interface end and two outlet interface ends are arranged on the valve housing; a guide close cover plate that can rotatably covering one inner interface of the two outlet interface ends is arranged in the inner cavity of the valve housing; hanging scrolls are respectively arranged at two sides in the middle of the guide close cover plate; the hanging scrolls extend out of the two side walls of the valve housing and are used for supporting scroll seats arranged outside the walls; wherein the end part of one hanging scroll is connected with one end of a connecting bar, and the other end of the connecting bar is connected with the end part of the piston rod of an air cylinder. The connection clearance, the close contact-surface groove and the exposed rotary scroll do not exist between the rotatable guide close cover plate and the valve housing in the inner cavity of the valve housing, thereby eliminating the conditions of tangling, gathering and stopping of the loose fiber, therefore, the two-position three-way auto-control valve has good leak tightness; in addition, the conveying commutation is smooth, thereby avoiding the conveying blockage of the loose fiber and the fiber damage; the operation is automatic and reliable, therefore, the efficiency is high.
Description
Technical field
The utility model relates to a kind of valve, particularly is applicable to the reversing control valve of staple in bulk airflow pipeline.
Background technique
The wool textile raw material pretreatment comprises scouring of wool, nutriment and operations such as hair, carding, and between each operation of this manufacturing process, it is the thing of a trouble that the hair raw material that looses is transported.Originally adopt man-handling of materials, labor intensity is big, efficient is low, and is big for environment pollution, and the working environment of workers is poor.At present, many enterprises carry the hair that looses and have adopted advanced pipe gas flow to carry, and have not only improved production environment well, and have improved manufacturing efficiency greatly.But in the existing pipe gas flow feedway, still there are many links to require further improvement, as pipeline flow-dividing control device, existing plate or the turnover panel structure of adopting mostly, need manually-operable, and the slit at plate, turnover panel place takes place easily to leak or fiber tangles to assemble and stops up.
Summary of the invention
The purpose of this utility model provides a kind of good airproof performance, does not have the staple in bulk airflow pipeline two-position three way autocontrol valve that stops up.
The technical solution that realizes above-mentioned purpose is: this valve comprises valve chest, valve chest is provided with an import interface end and two discharge coupling ends, and be provided with a water conservancy diversion capping plate that can revolve one of them inner port of moving two discharge coupling ends of capping in the valve chest inner chamber, both sides, described water conservancy diversion capping plate middle part are respectively equipped with hanging scroll, described hanging scroll stretches out the valve chest two side and is supported on the axle bed on the wall outside, wherein the end of a hanging scroll is connected with an end of connecting rod, and the other end of connecting rod is connected with the piston rod end of cylinder.
Be respectively equipped with flexible strip on described water conservancy diversion capping plate and valve chest internal chamber wall limit, contacted two ends and the dual-side.
The inner port wall of two discharge coupling ends of described valve chest is provided with and limit, the water conservancy diversion capping plate two ends flexible sealing liner plate of close fit mutually.
The beneficial effects of the utility model are: revolving in the valve chest inner chamber moved and do not had joint gap and sealing contact surface groove between water conservancy diversion capping plate and the valve chest, there is not exposed rotating shaft yet, eliminated and produced the condition that staple in bulk is entangled with, gathers, is detained, thereby the utility model good airproof performance; Carry commutation smooth and easy, stopped staple in bulk and carried obstruction and fiber damage phenomenon; Operation is reliable automatically, the efficient height.
Description of drawings
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2 is a water conservancy diversion capping plate structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
The valve chest 1 of present embodiment is the T type, and its vertical end is that import interface end 5, two horizontal ends are respectively discharge coupling end 3 and discharge coupling end 10, and each outlet end external port is equipped with adpting flange 11; But the water conservancy diversion capping plate 2 curved tiles of capping valve chest discharge coupling end inner port, plate body two middle side parts are respectively equipped with hanging scroll 9, two hanging scrolls 9 in same axle center pass valve chest 1 two side and are supported on the axle bed 12 on the wall outside, wherein the end of the hanging scroll 9 of a side connects an end of connecting rod 13, and the other end of connecting rod 13 is connected with piston rod 8 ends of cylinder 7 on being fixed in import interface end flange by bearing pin 4.Another embodiment of hanging scroll 9 adopts an axon that runs through both sides, water conservancy diversion capping plate 2 middle part, and fixing with the welding of both sides, water conservancy diversion capping plate 2 middle part.Be respectively equipped with flexible strip 14 on water conservancy diversion capping plate 2 and valve chest internal chamber wall limit, contacted two ends and the dual-side, the root of water conservancy diversion capping plate hanging scroll 9 is equipped with seal ring 15, and the inner port wall of two discharge coupling ends 3,10 of valve chest is provided with and limit, the water conservancy diversion capping plate two ends flexible sealing liner plate 6 of close fit mutually.
As shown in Figure 1, cylinder piston rod 8 stretches out, and water conservancy diversion capping plate 2 is in the inner port of the discharge coupling end 10 that is sealed on valve chest, and at this moment, valve body import interface end 5 connects with discharge coupling end 3; When cylinder piston rod 8 shrinks by setting stroke, drivening rod 13 turns an angle the hanging scroll 9 of water conservancy diversion capping plate 2, thereby make water conservancy diversion capping plate 2 revolve the inner port that moves to discharge coupling end 3 from the inner port of discharge coupling end 10, so valve body import interface end 5 connects with discharge coupling end 10.
