Technical Field

The invention relates to a dustproof gate valve with a self-cleaning function, and belongs to the technical field of valves.

Background

The opening and closing part of the gate valve is a gate plate, the moving direction of the gate plate is vertical to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. The gate has two sealing surfaces, the most common mode being that the two sealing surfaces of the gate form a wedge, the wedge angle varying with the valve parameters, typically 5 °, and 2 ° 52' for medium temperatures not high.

The prior art has the following defects that most manufacturers for producing gate valves in China are more, the connection sizes are mostly not uniform, the general types are mainly JB/T2203-1999 Gate valve structure length, most safety valve manufacturers in China are designed and produced according to the standard, and the prior art has the following defects: the inside relevant cleaning device that does not set up of current gate valve to lead to accumulational impurity in the gate valve too much, make rivers not smooth or the gate valve blocks up, and current gate valve inner structure is comparatively complicated, and the maintenance is inconvenient and the cost is higher.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the existing defects, provide a dustproof gate valve with a self-cleaning function, have the advantages of stronger cleaning function, simple internal structure, convenient maintenance and lower cost, and solve the problem that the impurities accumulated in the gate valve are too much to cause unsmooth water flow or the gate valve is blocked because no related cleaning device is arranged in the existing gate valve.

In order to achieve the purpose, the invention provides the following technical scheme:

a dustproof gate valve with a self-cleaning function comprises a valve body, wherein a gate plate is arranged in the valve body, a first bearing is mounted at the top of the gate plate, a threaded rod is movably connected to the top of the first bearing, a fixed seat is fixedly connected to the top of the valve body, and the top end of the threaded rod penetrates through the fixed seat;

the valve body both sides are equipped with inlet tube and outlet pipe, install clean mechanism on the inlet tube, clean mechanism includes ring body, second bearing, spherical filter screen, bull stick, semi-ring frame, cleaning brush, it is internal that the ring body is located to the spherical filter screen, spherical filter screen one end is passed through the second bearing and is connected the ring body, other end fixed connection bull stick, just bull stick one end runs through the ring body, the semi-ring frame is located one side that the valve body was kept away from to the spherical filter screen, just semi-ring frame fixed connection ring body, cleaning brush is located on the semi-ring frame inner wall.

Furthermore, a threaded hole is formed in the fixing seat, and the threaded hole is in threaded connection with the threaded rod.

Furthermore, the top end of the threaded rod is fixedly connected with a hand wheel, and the hand wheel is arranged above the fixed seat.

Furthermore, the one end that inlet tube and outlet pipe kept away from each other all is equipped with the flange, just be equipped with fixing bolt on the flange.

Further, the ring body passes through threaded connection inlet tube, just be equipped with the sealing washer between inlet tube and the ring body.

Furthermore, one end of the rotating rod is connected with a rotating handle, and the rotating handle is arranged on one side of the ring body.

Further, the valve body inner chamber is equipped with sealed the pad, just sealed pad is located between valve body and the flashboard.

The invention has the beneficial effects that:

1. through the arrangement of the valve body, the fixed seat, the threaded hole, the threaded rod, the first bearing, the flashboard, the hand wheel and other structures, the internal structure of the gate valve is simple, and the flowing rate of liquid can be effectively controlled;

2. by arranging the cleaning mechanism, water flow passing through the gate valve can be filtered, impurities are prevented from passing through, the problem that water flow is not smooth or the gate valve is blocked due to excessive accumulation of impurities in the gate valve is effectively avoided, the filter screen can be cleaned by the structure, the filter screen is prevented from being blocked by the impurities, and the service life is prolonged;

3. the gate valve is simple in overall structure, low in manufacturing cost and convenient to replace parts and maintain inside.
