Abstract
The utility model relates to the technical field of valves, in particular to an opening feed valve plate which is in a conveying gate valve device of dusts, or particles or semi-fluid mediums. The problems that leakage happens and a conveying system can not be closed normally of a double gate valve due to the fact that materials are stuck, a valve cavity is easy to jam and a valve plate is unbalanced are solved. The opening feed valve plate is characterized by comprising a body which is in a disc shape. The breadth face of the body is provided with a plurality of hollow parts, the center position of a plane of the body is provided with a counter bore, the diameter of the counter bore is matched with a gate valve swing arm, and the diameter of the body is larger than that of a discharge port of a gate valve. The opening feed valve plate is simple in structure, easy to assemble, dismantle and maintain. The weight of the opening feed valve plate is light, movement is flexible, and eddy winds which can clean an inner cavity of a valve are generated in operating process.
Description
Technical field
The utility model relates to valve technology field, especially relates to the perforate charging valve plate in all kinds of dust in a kind of industrial enterprise, particle or the semifluid medium transport gate-valve device.
Background technique
The industries such as thermal power plant, metallurgy, chemical industry adopt a large amount of double gate valves to carry out the conveying of all kinds of dust, particle, the particularly conveying of high temperature larger particles, double gate valve feeding and discharging bore of the prior art is mostly consistent, go out young, be unfavorable for carrying, easily stuck, valve pocket is easily stifled, and heat-resisting quantity is poor, causes leaking or transporting system can't just normally closed pressure.Be a kind of Pneumatic wear resistant double gate valve of CN201787103U such as patent publication No., establish piston rod in the pneumatic actuator assembly, one end of piston rod is provided with link, be provided with the spring seat vertical with piston rod in the link, the spring seat two ends are respectively equipped with flap, and two flaps cooperate with two side valve seats respectively, this solid not saturating structure of flap, be provided with the valve circle between two side valve seats, two flaps and spring seat are positioned at valve circle middle part containing space, and piston rod is provided with the connection neck towards an end of pneumatic final controlling element cylinder body.And for example patent announcement number is a kind of wear-resistant parallel double-flashboard gate valve of CN101886705A, feature is that corresponding recessed flashboard and protruding flashboard closed end are provided with the chamber that holds at least recessed flashboard and a stroke of protruding flashboard on the valve body, recessed flashboard is provided with the duct identical with cross section, valve body main passage with protruding flashboard, valve body main passage and duct on recessed flashboard and the protruding flashboard matched correspondingly when recessed flashboard was in full open position with protruding flashboard, and porthole edge is along being close to the sealing surface of valve seat.Because the valve plate of material feeding mouth and discharge port needs simultaneously action, the valve body feeding and discharging bore size of these two kinds of structures or identical, the discharge port valve board structure of these products is basic identical, all is solid construction, relative material feeding mouth, discharge port diminishes certainly relatively in operation process.
Summary of the invention
The purpose of this utility model is in order to solve double gate valve because material is stuck, valve pocket easily blocks up, valve plate is uneven, cause leaking and problem that transporting system can't just normally closed pressure, provide a kind of valve pocket of reasonable in design to be difficult for the dust stratification jam, the adaptation condition ability is strong, the perforate charging valve plate of long service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of perforate charging valve plate, it is characterized in that comprising body, described body is discoid, the breadth of body is provided with several hollow part, the central position on a plane of body is provided with counterbore, the diameter of this counterbore cooperates with the gate valve swing arm, and the diameter of body is greater than gate valve discharge port diameter.The design of hollow part, not only alleviated the weight of valve plate body, and in operation process, keep the balance of double-gate valve plate, the hollow out position in fact also plays eddy current wind and tells on, this to the cleaning valve internal, avoid the defectives such as various obstructions, buildup to have great significance.
As preferably, described hollow part is fan-shaped, is gusset between each hollow part.Hollow out on the disc structure can alleviate this body weight, but can not affect body structure intensity, and each face of gusset, angle are smooth.
As preferably, the circle at the large and small arc place that described hollow part is fan-shaped is concentric with this body diameter.Concentrically ringed fan-shaped design can reach maximum hole area.
As preferably, the thickness in described body center portion is greater than the thickness of edge, the radial cross section of the gusset trapezoid shaped that meets at right angles.Because the suffered jacking force of valve body comes from swing arm, i.e. the center portion of body, the design of the little conical surface makes body have higher structural strength.
Effective effect of the present utility model is: simple in structure, and easily assembling, dismounting and maintenance; Own wt is light, is active in one's movements, and can remain the eccentric effect to passage of discharge port in the operation process, when opening the drainage material, can produce eddy current, can clean voluntarily valve cavity.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the right TV structure schematic representation of the utility model Fig. 1.
Among the figure: 1. body, 11. hollow part, 12. counterbores, 13. gussets.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, a kind of perforate charging of present embodiment valve plate is established disc-shaped body 1, establishes 4 hollow part 11 on the breadth of body 1, and hollow part 11 is sector structure, and the circle at the large and small arc place that hollow part 11 is fan-shaped is concentric with body 1 disc structure.The thickness in body 1 center portion is greater than the thickness of edge, it is protruding to be that the center portion is provided with cylinder, platform cylinder boss vertically center is provided with counterbore 12, be 4 gussets 13 between 4 hollow part 11, the radial cross section of gusset 13 trapezoid shaped that meets at right angles, 45 ° of 2 х are fallen in each corner of gusset, the diameter of counterbore 12 and gate valve swing arm Spielpassung, the diameter of body 1 is greater than gate valve discharge port diameter, and namely during barrier gate, valve plate covers discharge hole fully.
Because the setting of hollow part 11, in the operation process, the actual ventilation of discharge port is always large than material feeding mouth, so will produce eddy current wind, can constantly clean valve internal.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any structure after the simple transformation of the present utility model is all belonged to protection domain of the present utility model.
