Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is further explained and illustrated;

[0023] like figure 1 As shown, an integrated inflation and exhaust valve for the pressure plate of the emptying pump for barrels includes an emptying pump barrel body, the pressure plate is located in the barrel body and is used in conjunction with it, the pressure plate is covered with a cylindrical valve body 3, and the barrel The lower end of the valve body 3 is fixed in phase with the bottom surface of the pressure plate, and the upper opening of the valve body 3 covers the valve cover 8, and the two are fixedly connected by bolts 10. The valve cover 8 has an inflation and exhaust port 11, and the valve body 3. The interior is divided into upper and lower chambers by a partition, and a spool hole is provided in the middle of the partition, and the inner diameter of the spool hole matches the outer diameter of the spool 1. The spool goes through the hole, an...

Abstract

The invention discloses an inflation and deflation integrated valve for an emptying pump pressure plate for a barrel. The inflation and deflation integrated valve comprises an emptying pump barrel body, the barrel body is provided with the pressure plate, the pressure plate is sleeved with a cylindrical valve body, a movable valve element is arranged in the valve body, an upper opening of the tubular valve body is connected with a valve cover, the valve cover is provided with an inflation and deflation port, the inside of the valve body is divided by a partition plate into upper and lower cavities, the valve element penetrates through a valve element hole in the partition plate, the upper and lower parts of the partition plate are provided with limiting pieces, the lower end of the valve element is a sealing end panel used in cooperation with a lower opening of the valve body, a T-shaped or crossed-shaped vent hole is formed in the valve element, and the upper and lower cavities are communicated. By means of the inflation and deflation integrated valve, only one valve body is used, the number of manual operation is decreased, and the valve is more convenient to use. The valve is closed after deflation, the valve is opened after inflation, the pressure plate descends, pneumatic operation is automatically completed, no manual participation is needed, the contact between a mediumand the human body is avoided, and the safety of the device is strengthened.

Description

technical field [0001] The invention relates to an emptying pump for barrels, in particular to an integrated inflation and exhaust valve used on the pressure plate of the emptying pump for barrels. Background technique [0002] When the bucket emptying pump is in use, when conveying the medium with poor fluidity, it is necessary to use the pressure plate to apply pressure on the medium so that the medium can enter the pump inlet smoothly. There is a sliding seal between the rubber pressure plate and the barrel wall. Therefore, in the process when the pressure plate enters the mouth of the barrel and has not touched the medium, in order to make the pressure plate enter the barrel better, the air between the pressure plate and the medium needs to be drained, and the pressure plate touches the medium when the pressure plate descends. Finally, the exhaust function should be turned off to prevent the medium from being squeezed out by the pressure of the platen. After the medium ...
