Embodiment Construction

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] see figure 1 and figure 2 , the double-diaphragm pump alarm detection pressure-taking structure of the present invention includes a cylinder body 1, a cylinder head 2, a pressure-taking ring and a double diaphragm composed of an oil diaphragm 3 and a material diaphragm 4, and the edges of the oil diaphragm 3 and the material diaphragm 4 are fitted together Together, a cavity 5 is formed in the middle, and the periphery of the double diaphragm is fixedly installed in the cylinder and separates the power chamber and the fluid delivery chamber. The pressure-taking ring is located on the periphery of the peripheral surface of the double diaphragm. The pressure-taking ring is composed of an inner ring 6 and an outer ring 7 that are fitted side by side. The left and right sides of the inner ring 6 are respectively provided with a ri...

Abstract

The alarm detection pressure tapping structure for the double-diaphragm pump comprises a cylinder body, a cylinder cover, a pressure tapping ring and double diaphragms, the pressure tapping ring is composed of an inner ring and an outer ring, ring grooves are formed in the two side faces of the inner ring respectively, and the inner ring is provided with a plurality of axial sampling channels for communicating the ring grooves in the two sides. And a pressure taking channel is arranged on the cylinder body and is communicated with the annular groove on one side. The attaching position of the inner ring and the outer ring extends towards the inner wall face of the diaphragm to form a thin-wall annular extending part, the thin-wall annular extending part of the inner ring and the thin-wall annular extending part of the outer ring are attached together to form an annular sampling part, and the annular sampling part is clamped between the edge of the oil diaphragm and the edge of the material diaphragm in a closed mode; a plurality of radial sampling channels are formed in the annular sampling part along the circumference, one end of each radial sampling channel is communicated with the double-diaphragm cavity, and the other end of each radial sampling channel is communicated with the annular groove in the other side. The structure can effectively solve the problem that the diaphragm enters the pressure tapping channel under high pressure to cause blockage, and the reliability of pressure tapping and detection is improved.
