Abstract
The invention relates to a whole-sealing leakage-free inserting plate door which is used in a powdery and grain material conveying control system. The whole-sealing leakage-free inserting plate door comprises a valve body with an inner cavity, wherein a material channel is arranged in the middle of the valve body; a pair of valve seats which surround the material channel are arranged in the inner cavity of the valve body; an inserting plate which can be adhered to opposite side surfaces of the valve seats and translate relative to the valve seats is arranged between the pair of valve seats; the material channel can be opened or closed through the movement of the inserting plate; the inner cavity of the valve body is communicated with a positive pressure air source through an air inlet, so that compressed air can be introduced into the inner cavity of the valve body. The whole-sealing leakage-free inserting plate door ensures that dust and materials in the material channel can not leak off, the valve opening and closing force is stable, mediums can be cut off stably, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of Full-enclosed leakless insertion plate door for powdery, granular material transport control system.
Background technique
In the system for delivery of flying dust, particle (powdery) dry material, insertion plate door is used for material conveying passage is opened or ended control, can be installed in the ash bucket bottom such as coal pulverizer, economizer, air preheater, dry collector, flue of the industries such as electric power, building materials, metallurgy, mine, chemical industry, glass, light industry, grain, also can support the use with electric feeder.Large in some control changes in flow rate, start frequent, cut off frequency and the higher occasion of rate request, existing insertion plate door easily causes bad sealing, material from leakage because of sealing surface wear.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of sealing effect good, be difficult for leaking, seal clearance is adjustable, the Full-enclosed leakless insertion plate door of reliable in action, long service life.
Full-enclosed leakless insertion plate door of the present invention comprises the valve body with inner chamber, the valve body middle part is provided with material channel, be provided with a pair of valve seat around material channel in the body cavity, be provided with between a pair of valve seat can with the valve seat opposite flank be affixed merging can with the plate of valve seat relative translation, but the described material channel of movement opening and closing of fault of plate; Described body cavity is communicated with the malleation source of the gas by suction port, can pass into pressurized air in body cavity.
Be provided with the adjusting bolt that to regulate a pair of valve base chamber distance on the described valve body.
Be lined with sealing gasket between described valve seat and the valve interior surface.
The present invention makes the faying surface outside of valve body and valve seat be in positive pressure environment by pass into pressurized air in valve body, can guarantee that dust and the material in the material channel can't be overflowed; By the adjustable structure of valve seat so that valve seat and plate can obtain best gap, make plate close with opening process in be close to motion with valve seat, thereby make valve opening and closing power stable, can cut off stably medium; In addition, by the regulating valve seat spacing, wearing and tearing that can compensating unit, thus improve working life.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Embodiment
As shown in the figure, this Full-enclosed leakless insertion plate door comprises the valve body 1 with inner chamber, the valve body middle part is provided with material channel 2, be provided with a pair of valve seat 3 around material channel in the body cavity, be provided with between a pair of valve seat can with the valve seat opposite flank be affixed merging can with the plate 4 of valve seat relative translation, but the described material channel of movement opening and closing of fault of plate; Described body cavity is communicated with the malleation source of the gas by suction port 5, can pass into pressurized air in body cavity.Be provided with the adjusting bolt 6 that to regulate a pair of valve base chamber distance on the valve body, adjusting bolt shown in the figure can arrange the direction parallel with the power of inserting, adjusting bolt can be converted into the adjusting driving force of level by driving the modes such as Wedge mechanism the adjusting power of vertical direction, with the Vertical direction position of regulating valve seat.Be lined with sealing gasket 7 between valve seat 3 and valve body 1 internal surface.Plate 4 drives by pull bar 8, and it can be manual, electronic or pneumatic driving power.Also be provided with access door 9 on the valve body, be used for the parts in the inner chamber are overhauled.
