TH6858B - Two-stage diaphragm pump with two-stage valve actuator - Google Patents

Abstract

The double diaphragm pump is operated by selectively switching compressed air into either of the two chambers. The diaphragm valve actuates the air into a sliding cup flap. On the ejector in the valve plate, it can be opened and actuated by an air piston. This air piston is coupled via a channel to the guide flap, a second sliding cup-type flap on the ejector in the flap plate. The actuated cup-type valve with a latch extends into the diaphragm chamber and comes into contact with the diaphragm element at a pre-determined position.

Say shaft With the so-called individual diaphragms: d) the intra-valve chamber, the so-called central shield, and the device for conveying pressurized air into the so-called actuator valve chamber, e). Propulsion valve in the so-called actuation valve It consists of a sliding valve cartridge on the valve plate, known as the valve plate. There are three aligned passages, which consist of a central channel that is connected to a vent and another, each connected through a passage with Each chamber of the so-called diaphragm chamber, and consists of an adorned heat exchanger known as the cartridge valve, f) a pair of thrust valve control pistons connected to the so-called throttle valves, And air through the regulator in the so-called cover in connection of the flow with the so-called piston control, g) the lead valve in the so-called actuator valve chamber, in connection with that of the air flow with The so-called air pass regulator, and there is a device to respond to the position of the so-called diaphragm that is already predetermined to drive the so-called pair of piston-controlled throttle valves, and h) the vent chamber. This is called the middle cover, and the passageway that connects the so-called shimmer chamber to the so-called pilot valve. And called the actuation valve vent 6. The success of claim 5, hereinafter referred to as the heat exchanger, also consists of metal assemblies. Fins Which extends into the so-called actuator chamber 7. The successor of claim 6, hereinafter referred to as a pilot valve device in response to a predetermined position of the so-called diaphragm, is also equipped with a group of bolts installed. Movable type in the so-called center cover. And there is one end each protruding into each of the diaphragm chambers, and there is a second end connected to the so-called pilot valve. 8. The completion of claim No. 7, hereinafter referred to as the pilot valve, is additionally equipped with a cartridge valve. The so-called valve plates, also known as the valve plates, have three aligned passages consisting of a central channel connected to the so-called vent chamber, and the other, each connected to a passage. Which leads to the so-called piston driven valve control. 9. The unit of claim No. 8 is also equipped with a silencer connected to it called the vent chamber 1. 0.
