Problems solved by technology

[0012] 1. Excess water from the pump head cover is discharged from the water pressure discharge port. Although it can be diverted into a general container for collection and reuse, it also increases the trouble for the user to reserve another container, or it cannot be used due to too much accumulated water. It is inconvenient to reuse all t

Abstract

The present invention provides a diaphragm pump of constant pressure type, mainly wherein a passage tube links between said pressure discharge port and said inlet port of said pump cover body; Thereby, the extra water pressure coming from said compressed chamber can be orderly discharged through said pressure discharge port, next guided through said passage tube to reach said inlet port, then directly flowed into said low pressure chamber; Therefore, a close water circulation loop of discharge pressure is built by means of connecting said compressed chamber, said pressure discharge port, said passage tube, said inlet port and said low pressure chamber; Thus, the present invention not only provides the function of keeping constant pressure, but also completely recycles the drained water by extra water pressure without any waste in water resource; Moreover, the present invention not only has the energy-saving effect in power consumption, but also has the environment-protecting effect in reducing operation noise; Thus, it is really an innovative invention with multiple practical effect.

Description

(1) Technical field [0001] The invention relates to a constant pressure diaphragm pump which is related to a pressure diaphragm pump dedicated to reverse osmosis purification, and in particular refers to a pressure diaphragm pump capable of venting the excessively high water pressure in the high-pressure water chamber of the pressure diaphragm pump to The pump head cover is outside of the body, and it is directly directed to the water inlet and then re-injected into the low pressure water chamber in the pump head cover to achieve the expected constant pressure value at the outlet of the pump head cover. (2) Background technology [0002] Currently known types of pressure diaphragm pumps used in reverse osmosis water filters, such as U.S. Patent Nos. 4396357, 4610605, 5476367, 5571000, 5615597, 5264464, 5649812, 5706715, 5791882, 5816133, 6048183, 6089838, 6299414, 6604909, 6840745 and No. 6892624, etc. have all been exposed, and the pressure diaphragm pump dedicated to the conven...
