Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0016] As shown in the figure, the pressing pressure exchange device is composed of a first housing 8, a second housing 9, a third housing 16, a fourth housing 19, and a fifth housing 21 connected to each other. The outer cover 52 constitutes the buffer chamber 32; the first elastic sheet 1 is arranged between the first housing 8 and the second housing 9 to form the first cavity 7, and the second housing 9 is provided with a micro-opening valve core 5, which is micro-opened. The left end of the valve core 5 is fixedly connected with the first elastic piece 1; the second elastic piece 40 is arranged between the second housing 9 and the third housing 16 to form the second cavity 12, the third cavity 13, and the third housing 16 The air outlet rod 47 is arranged on its left and right sealing and sliding cooperation, and the left end of the air outlet ro...

Abstract

The invention relates to a pressing pressure exchange device, and belongs to the technical field of pressure exchange devices. The pressure exchange device is composed of a first shell, a second shell, a third shell, a fourth shell and a fifth shell which are mutually connected, and an outer cover is cooperatively arranged above the shell to form a buffer cavity; a first elastic piece, a second elastic piece, a first cavity, a second cavity, a third cavity, a high-pressure cavity and a fourth cavity are arranged between the shells. Starting and shutdown of the pressing pressure exchange devicehave delay performance, the time is controllable, the response speed is high, and sewage discharge is thorough; the device is not easy to damage in a humid environment, long in service life, suitablefor long-distance drainage of toilet and kitchen drainage pipes and suitable for cruises and other places needing distributed centralized drainage.

Description

technical field [0001] The invention belongs to the technical field of pressure exchange devices, in particular to a pressure exchange device. Background technique [0002] In the existing residential quarters, the drainage from the toilet and kitchen is directly discharged to the gravity pipe. If it is necessary to renovate a toilet at a place far away from the gravity pipe, the sewage discharge from the drain pipe to the gravity pipe can be realized through a pressure exchange device. Conventional pressure exchange generally uses solenoid valves or manual valves. Manual valves are used for pressure exchange, and the time is uncontrollable and the response speed is slow; while solenoid valves are easily damaged in humid environments and have a short service life. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the object of the present invention is to design and provide a technical solution for pressing the pressure ex...
