Description
(I) technical field
The invention relates to powder flow control equipment, in particular to a gate opening air-reversing gate valve with a gate opening air-reversing function.
(II) background of the invention
The gate valve is a flow control device commonly used for powder treatment equipment, and is widely applied due to simplicity and reliability.
The gate valve has various forms such as pneumatic, electric and manual, and the pneumatic gate valve is the most common.
When the gate valve is applied to powder treatment equipment, the powder is easy to adhere to the gate, so that the sealing environment between the outer cavity of the gate and the inner cavity of the powder becomes severe. After the gate valve operates for a long time, due to the fact that the abraded sealing gasket of the powder is easy to leak, a large amount of powder is accumulated in the outer cavity of the gate valve, and the gate valve cannot work finally.
In order to solve this problem, patent document No. 201711471384.5 proposes: the proposal of sealing the valve plate and the valve rod independently is adopted, but the dust accumulation problem is still not solved.
Some gate valves connect with the return pipe at the lower plate of the outer cavity, so that the accumulated powder flows back to the discharge bin, and although the problem of large amount of accumulated powder is solved, the cylinder rod and the sealing thereof, and the gate seal work in a dust environment, and the cylinder and the gate seal are seriously abraded.
Disclosure of the invention
Aiming at the defects, the outer cavity of the gate valve is sealed, and the gas one-way valve is arranged, so that the sealing cavity is filled with air when the gate valve is closed; when the gate valve is opened, air is discharged from a gap between the gate and the gate seal, and dust is prevented from entering the outer cavity, so that the gate and the gate seal are cleaned.
The invention aims to provide the following steps: through the simple improvement to current push-pull valve, effectively solve the push-pull valve exocoel powder and pile up, guarantee that push-pull valve work is smooth and easy, reduce push-pull valve resistance and the wearing and tearing that picture peg and picture peg are sealed, extension push-pull valve working life.
The purpose of the invention is realized as follows:
the air cylinder and the air cylinder rod thereof are connected with the plugboard through the connecting plate; the upper sealing plate and the lower sealing plate are hermetically connected with the outer frame; the cylinder, the cylinder rod, the upper sealing plate, the lower sealing plate, the outer frame, the inserting plate seal and the gas check valve form a sealing cavity which can only feed gas through the gas check valve;
closing the gate valve: the air rod pushes the air cylinder rod to drive the plug board to move leftwards to seal the feed opening, the sealing cavity forms negative pressure due to the pushing of the plug board, the air one-way valve is opened, and air enters the sealing cavity;
opening a gate valve: the gas pole promotes the cylinder pole and drives the picture peg and move right and open the feed opening, because the insertion of picture peg, the sealed chamber forms malleation pressure, and gaseous check valve is closed, and the air gets into the feed opening through the sealed clearance of picture peg and picture peg by sealed chamber. Because the insertion of the insertion plate and the air discharge move oppositely, dust in the feed opening cannot enter the sealing cavity, and therefore the sealing cavity and the air cylinder rod are guaranteed to work in a clean environment.
(IV) description of the drawings
The specific structure of the invention is given by the following embodiments and the attached drawings:
fig. 1 is a front sectional view of the structure of the present invention, and fig. 2 is a top view of the structure of the present invention.
The device comprises an air cylinder (1), an air cylinder rod (2), an upper sealing plate (3), a lower sealing plate (4), a connecting plate (5), an inserting plate (6), an inserting plate seal (7), an ash scraping strip (8), a discharging opening (9), a roller (10), an air cylinder electromagnetic valve (11), a gas one-way valve (12), an outer frame (13), an inner frame (14) and a sealing cavity (15).
The air cylinder (1) and the air cylinder rod (2) thereof are connected with the plugboard (6) through the connecting plate (5); the upper sealing plate (3) and the lower sealing plate (4) are hermetically connected with the outer frame (13); the air cylinder (1), the air cylinder rod (2), the upper sealing plate (3), the lower sealing plate (4), the outer frame (13), the inserting plate (6), the inserting plate seal (7) and the air one-way valve (12) form a sealing cavity (15) which can only admit air through the air one-way valve (12).
The drawings are only for convenience of description, and the pneumatic gate valve is adopted, and other manual gate valves and electric gate valves can be adopted according to the working requirement.
(V) detailed description of the preferred embodiments
Installation according to the attached drawings and the description of the attached drawings:
(1) the device comprises an air cylinder, (2) an air cylinder rod, (3) an upper sealing plate, (4) a lower sealing plate, (5) a connecting plate, (6) an inserting plate, (7) inserting plate sealing, (8) an ash scraping strip, (9) a discharging port, (10) a roller, (11) an air cylinder electromagnetic valve, (12) an air one-way valve, (13) an outer frame, (14) an inner frame and (15) a sealing cavity.
The working process of the invention is as follows:
1. closing the gate valve: the air rod (1) pushes the air cylinder rod (2) to drive the insertion plate (6) to move leftwards to seal the feed opening (9), the sealing cavity (15) forms negative pressure due to the pushing of the insertion plate (6), the air one-way valve (12) is opened, and air enters the sealing cavity (15) from the negative pressure.
2. Opening a gate valve: the air rod (1) pushes the air cylinder rod (2) to drive the insertion plate (6) to move rightwards to open the feed opening (9), positive pressure is formed in the sealing cavity (15) due to the insertion of the insertion plate (6), the air one-way valve (12) is closed, and air enters the feed opening (9) from the sealing cavity (15) through a gap between the insertion plate (6) and the insertion plate seal (7). Because the insertion of the insertion plate (6) and the air discharge move oppositely, dust in the feed opening (9) can not enter the sealing cavity (15), thereby ensuring that the sealing cavity (15) and the air cylinder rod (2) work in a clean environment.
Compared with the existing gate valve, the gate valve has the following characteristics:
1. the flashboard (6) and the flashboard seal (7) are automatically cleaned in the working process.
2. The fit between the insert plate (6) and the insert plate seal (7) does not require a high degree of precision.
3. Because the matching between the inserting plate (6) and the inserting plate seal (7) does not require tight matching, the frictional resistance between the inserting plate (6) and the inserting plate seal (7) is reduced, the working power of the cylinder (1) can be effectively reduced, the abrasion of the inserting plate (6) and the inserting plate seal (7) is reduced, and the service life of the inserting plate valve is prolonged.
