Abstract
The utility model belongs to a valve member which is a rocker discharge locking valve. The characteristic is that a valve body is equipped with a discharge valve (6) and an additional weight valve plate (6a) which are rocking around an arbor (3). The additional weight (5) is arranged besides vertical quadrant of the additional weight valve plate, a movable sealing plate (2) which fits accurately with the additional weight valve plate is arranged on the valve body, and an inspection gate (4) is arranged on the valve body. The utility model that can achieve high performance of discharging and locking, simple structure, low cost, environmental protection and energy-saving, wide applicability and convenient installing and servicing is ideal common apparatus of discharging and locking of construction material, metallurgy and chemical industry and the like product line.
Description
One, technical field
The utility model belongs to valve member, is specifically related to a kind of discharge gate with closure member.
Two, background technology
In the kiln tail preheating precalcining system of dry cement production line, on every grade of whirlwind tube discharge duct a discharging airlock is arranged all, the overwhelming majority all adopts the weight flap valve at present; At cement and metallurgy industry many large-scale bag collectors are arranged, its discharging lock wind generally adopts revolution discharger or electronic pair of flap valve etc.But above-mentioned discharging lock wind devices, its discharging and lock wind performance are all undesirable, and it is serious to leak out, the kiln tail returns ash and measures greatly or cause reentrainment of dust, and putty or shorten life of bag filter very easily, thereby directly influence the running of whole production line, cause bigger economic loss.In addition, in the prior art, to the discharge lock elegance gamma radiation tube sealing that increases the material length of tube of shaft kiln, this mode can cause the harm of gamma radiation to human body, and increases investment cost.
Three, summary of the invention
Goal of the invention of the present utility model is the defective that exists at above-mentioned prior art, designs a kind of discharging and lock wind is effective, simple in structure, cost is low, swing discharging air valve door applied widely.
The technical solution of the utility model is as follows.
A kind of swing discharging air valve door includes valve body and flange, it is characterized in that: on valve body top the movable sealing piece is installed, offers inspection door at the valve body middle part, be provided with a single mandrel and lateral support in valve body on valve body; On axle, be with a sleeve pipe, and be provided with discharging valve plate and counterweight valve plate and Socket welding and be connected together, steady ring is housed at the sleeve pipe two ends; Counterweight valve plate and movable sealing piece are precision-fit, are respectively equipped with counterweight in the vertical quadrant both sides of counterweight valve plate.
Adopt the discharging air valve door of the utility model structure, can realize installation, inspection and maintenance by inspection door, and counterweight is regulated, can counterweight be increased and decreased according to the difference of the positive negative pressure of operating mode to accessory in the valve body; When discharge not, because the effect of counterweight makes valve plate be in lock wind state; During discharge, along with material reaches constant weight valve plate is swung, material is extruded from the valve plate slide down, how many sizes of valve plate pivot angle is directly proportional with supplied materials, in the process of discharge, because counterweight valve plate and movable sealing piece are precision-fit, thereby the movable sealing piece can produce slip along with the swing of valve plate, make valve plate always be in sealing state, can not leak out.The swing discharging air valve door of the utility model structure in operational process not only energy free consume but also noise-less pollution environmental protection and energy saving; Discharging is unobstructed and lock wind is effective; Cost simple in structure is low; It is applicable to that bulk, granular material carry, and also adapts under the operating mode of high temperature, normal temperature or malleation, negative pressure and moves, and it is the vertically discharging discharging of also tilting both, and is applied widely; In addition, install during use, to overhaul and change part convenient, fast again.In a word, the swing discharging air valve door of the utility model structure is a comparatively ideal discharging lock wind common apparatus on the industry product manufacturing lines such as building materials, metallurgy, chemical industry compared with prior art.
Four, description of drawings
