Description
Technical field
The utility model relates to be used for powder conveying valve technology field, especially a kind of powder recycling conveying sealing valve
Door.
Background technique
Valve is widely used in the industries such as metallurgy, building materials, petroleum, chemical industry, is indispensable in current industrial production and not
Alternative product.The major function of valve is to control the on-off of pipeline, and the requirement for valve is, when opening in pipeline
Medium is smooth to be passed through, and when closure reaches reliable sealing, function-stable, stands adverse circumstances i.e. high temperature, bonding, corrosion and punching
Brush, has the performance of the sealed reliables such as anti-corrosion, wear-resisting, high temperature resistant.Due to needing in the pipeline of powder recycling and conveying equipment
The valve being frequently opened and closed, it is more stringent to the sealing requirements of valve, and sealing element is prone to wear in powder removal process.
Utility model content
Technical problem to be solved in the utility model be exactly be leakproofness for above-mentioned valve in the prior art compared with
It is low, and the deficiency that sealing element is prone to wear in powder removal process, a kind of powder recycling conveying sealed valve is provided.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of powder recycling conveying sealed valve,
Including valve body, valve plate, annular gas-flow closure circle and gas tube；The valve plate is rotated on the valve body by rotary shaft；Institute
Gas-flow closure circle is stated to be fixed on the valve body by fixed ring；When the gas-flow closure circle is inflated by gas tube described in contact
Valve plate is to make its valve seal.
Preferably, the valve plate and the rotary shaft are on the non-same center of circle.
Preferably, the side of the gas-flow closure circle is open end, and the other end is closed end；Wherein the side of open end is embraced
The tight fixed ring, and fixed by flat head screw；There is a gap closed end with the valve plate in on-inflatable, and valve plate can be with
It is rotated freely on valve body, when inflation, the gas-flow closure circle tightly embraces valve plate after inflating by gas tube.
Preferably, the outside of the valve is provided with solenoid valve.
Compared with prior art, the utility model has the beneficial effects that the utility model has, structure is simple, user
Just, valve plate is rotated on the valve body by rotary shaft；Gas-flow closure circle is fixed on the valve body by fixed ring；It inflates close
Seal contacts the valve plate to make its valve seal when inflating by gas tube, valve seal effect is good and recycles in powder
Sealing element is not allowed easy to wear in journey, to extend life of valve.
Detailed description of the invention
Fig. 1 show status diagram when the utility model gas-flow closure circle is not ventilated；
Fig. 2 is shown when the utility model gas-flow closure circle is ventilated and the status diagram of valve plate；
Fig. 3 show the deflation of gas-flow closure circle and replys nature closed mode schematic diagram；
Fig. 4 show the status diagram that valve plate is opened after gas-flow closure circle is deflated.
In attached drawing: 1 being valve plate, 2 be gas-flow closure circle, 3 be fixed ring, 4 be gas tube, 5 be valve body, 6 be solenoid valve, 7
It is rotary shaft.
Specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.It should be appreciated that described herein
Specific embodiment is only used to explain the utility model, is not used to limit the utility model.
As shown in Figs 1-4, a kind of powder recycling conveying sealed valve, including valve body 5, valve plate 1, annular gas-flow closure circle
2 and gas tube 4；The valve plate 1 is rotated on the valve body 1 by rotary shaft 7；The gas-flow closure circle 2 is solid by fixed ring 3
It is scheduled on the valve body 5；The gas-flow closure circle 2 contacts the valve plate 5 to keep its valve close when inflating by gas tube 4
Envelope.
As the further improvement of above-described embodiment, hole is opened up for prevent the gas-flow closure circle 2, guarantees its sealing effect
Fruit, the valve plate 1 and the rotary shaft 7 are on the non-same center of circle, to avoid the center line of gas-flow closure circle 2.
As the further improvement of above-described embodiment, imitated for the ease of the installation of gas-flow closure circle 2 and better seal
Fruit, the side of the gas-flow closure circle 2 are open type, and the other end is closed；The side of its split shed holds the fixed ring tightly,
And fixed by flat head screw, there is certain interval in closed end with the valve plate 1 in on-inflatable, and valve plate 1 can be on valve body 5
It rotates freely, reduces its resistance and abrasion, gas-flow closure circle 2 tightly embraces valve plate 1 after inflating by gas tube 4, guarantees that its is close
Feng Xing.
As the further improvement of above-described embodiment, solenoid valve 6 is provided on the outside of the valve；The solenoid valve is used
In the rotation of the on-off and rotary shaft 7 of the gas tube 4.
Above-mentioned technical proposal in order to facilitate understanding, as shown in Figure 1, status diagram state when gas-flow closure circle is not ventilated,
Valve closing under natural conditions, have certain gap between gas-flow closure circle 2 and valve plate 5, gap control in 1-5mm,
For reducing rotary resistance and abrasion of the valve plate 5 on valve body 1.As shown in Fig. 2, gas-flow closure circle ventilate when and valve plate signal
State diagram, gas-flow closure circle 2 tightly embrace valve plate 1, guarantee its leakproofness；As shown in figure 3, gas-flow closure circle, which is deflated, replys nature
Closed mode schematic diagram, gas-flow closure circle 2 leave valve plate 1；As shown in figure 4, the state that valve plate 1 is opened after the deflation of gas-flow closure circle
Schematic diagram, valve opening state, gas-flow closure circle 2 open valve after deflating, and rotary shaft 7 realizes rotation under the control of solenoid valve 6
Transhipment is dynamic and controls the closure or openness of gas tube 4.
The utility model has structure simple, easy to use, and valve plate is rotated on the valve body by rotary shaft；It inflates close
Seal is fixed on the valve body by fixed ring；Gas-flow closure circle contacts the valve plate to make it when inflating by gas tube
Valve seal, valve seal effect it is good and in powder removal process sealing element do not allow it is easy to wear, to extend life of valve.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
