Abstract
The utility modeldiscloses a double-layer two-way gate valve which comprises a valve body adopting a square structure. The gate valve is characterized in that double layers of gate plates including a first gate plate and a secondgate plate are arranged in the valve body and provided with respective sliding tracks including a first track and a second track, the first gate plate slides along the first track, the second gate plate slides along the second track, the first gate plate and the second gate plate are arranged on two sides of the valve body oppositely, and a hand wheel is arranged on the side surface of each gate plate; blanking holes are formed in the upper side and the lower side of the valve body respectively, and peripheral sides of each blanking hole are connected through flanges. The double-layer two-way gate valve effectivelysolves the problems that a one-way gate valve cannot be tightly closed and is difficult to close, and protects the environment from being affected by scattering of raised dust; and the labor intensity for field cleaning is reduced, deformation and abrasion of the valve are reduced, and the service life is prolonged by more than 4 times compared with the one-way gate valve.
Description
Technical field
The utility model relates to a kind of double-layer double-direction gate valve, belongs to mechanical field.
Background technique
Taiyuan Iron and Steel Co. equipment Imported From German EMH Company vertical mill system operating mine ground-slag in 2010, its basic technology be slag through Belt Conveyors carry and feed that Vertical Mill is dried, grinding and select powder, meal and the material overflowing are admitted to Vertical Mill grinding again, fine powder enters bag filter and carries out gas solid separation with going out to grind gas, and the fine powder of collection is finished product slag powders.The qualified superfine powder of producing through Vertical Mill enters finished stock storeroom, because of 10,000 tons of on-the-spot finished product storage capacity, at blanking position, bottom of the reservior, adopt unidirectional gate valve to block logistics, avoid superfine powder to be scattered everywhere, but in long-term actual using process, find to make the gate valve can not Close All because unidirectional gate valve enters superfine powder granule materials and long-term weight, do not have the effect of damming, affect site environment.
The at present domestic gate valve for granular material or granular material cut-off is unidirectional, single layer structure, this kind of valve mechanism, weight are comparatively simple, cost is lower, three fraud points of main existence in the middle of actual using process: the twice that (1) unidirectional gate valve work area is bidirectional flashboard valve, therefore its stroke and bearing capacity are just the twice of bidirectional flashboard valve, make gate valve active force in unlatching or closed condition process larger, opening speed is slower; (2) unidirectional gate valve is simple in structure because of itself, and valve body rigidity is not enough, and distortion flashboard curved in tracks is not parallel, causes flashboard to close difficulty; (3) unidirectional gate valve only has an operative orientation, and material is very easily stuck in flashboard track in actual use, causes flashboard not close completely, and dust is scattered.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of double-layer double-direction gate valve, effectively solves unidirectional gate valve and is not closed completely, closes difficult problem, and having avoided airborne dust to be scattered affects environment; Reduce on-the-spot cleaning labor intensity, the distortion of valve and wear and tear lessly, compares the life-span and improves more than 4 times with unidirectional gate valve.
The technical solution adopted in the utility model is: a kind of double-layer double-direction gate valve, comprise valve body, valve body is square structure, it is characterized in that: in described valve body, be provided with double-deck flashboard: the first flashboard and the second flashboard, every shoe brake plate arranges respectively an independent sliding rail: the first track and the second track, and the first flashboard slides along the first track, and the second flashboard slides along the second track, the first flashboard and the second flashboard are for being oppositely arranged at valve body both sides, and flashboard side is provided with handwheel; Valve body upper and lower sides has blanking hole, and periphery is connected by flange.
Described flashboard connects manual plate wheel by screw rod respectively, controls it slide along track by manual plate wheel.
Tradition individual event gate valve work area is large, so its stroke and bearing capacity be just the twice of bidirectional flashboard valve, makes gate valve active force in unlatching or closed condition process larger, and opening speed is slower; And unidirectional gate valve is simple in structure because of itself, and valve body rigidity is not enough, distortion flashboard curved in tracks is not parallel, causes flashboard to close difficult phenomenon; Way and double-layer gate valve of the present invention changes traditional individual layer one-way only operation tactic pattern, adopts the design of bilateral bi-directional, greatly improves rigidity and the utilization efficiency of product.
The double-layer double-direction gate valve that the utility model provides, the beneficial effect bringing:
(1) change traditional one-way only operation flow process, adopt two-way independent operation, avoided unidirectional flashboard to answer slot to have the phenomenon that foreign matter is stuck, flashboard cannot cut out comprehensively, sealing effect is good;
(2) double-layer double-direction gate valve adopts two shoe brake plates, every shoe brake plate is compared to one-way single-layer gate valve area reducing 1/2, and every shoe brake plate has an independent sliding rail, the surface friction drag of every shoe brake plate is reduced to half of original Single disc, and stroke also can shorten half, reduce closing gate, opening time;
(3) double-layer double-direction gate valve is because adopting way and double-layer sliding rail, so valve weight and rigidity reinforced, and not yielding, flashboard sliding effect is good;
(4) install and change conveniently, save the repair time.
The utility model is particularly useful for the control working environment that dams that mine, building materials, iron and steel, building etc. exist granular material or granular material.
Below in conjunction with drawings and Examples, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is valve body, and 2 is the first flashboard, and 3 is the second flashboard, and 4 is the first track, and 5 is the second track, and 6 is blanking hole, and 7 is flange, and 8 is screw rod, and 9 is manual plate wheel.
Embodiment
Embodiment:
As shown in Figure 1, a kind of double-layer double-direction gate valve, comprise valve body 1, valve body 1 is square structure, it is characterized in that: in described valve body 1, be provided with double-deck flashboard: the first flashboard 2 and the second flashboard 3, and every shoe brake plate arranges respectively independent sliding rail: the first track 4 and the second track 5, the first flashboard 2 slides along the first track 4, the second flashboard 3 slides along the second track 5, and the first flashboard 2 and the second flashboard 3 are for being oppositely arranged at valve body 1 both sides, and flashboard side is provided with handwheel; Valve body 1 upper and lower sides has blanking hole 6, and periphery is connected by flange 7.
