Problems solved by technology

The four-way reversing valve in this scheme has the following defects: 1. The shell adopts a cylindrical structure, and a plurality of cylindrical interfaces are also arranged on the cylindrical shell. The arc-shaped edge and the straight-line edge are spliced ​​together, and the shell is either cast or spliced ​​by more complicated process steps. The manufacturing process is more complicated and the manufacturing cost is higher; 2. Two cylinders are used to drive separately The two blocking parts jointly realize the reversing operation, the control program is relatively complicated, the types and numbers of parts are large, and the manufacturing and maintenance costs are relatively high

Embodiment 1

[0045] Such as figure 1 As shown, a fully automatic tube brush online cleaning system is placed in a water circulation loop composed of a cooling tower 1, a cooling water pump 2 and a heat exchanger 3. It specifically includes a sliding brush assembly (the sliding brush assembly is composed of a nylon brush and a brush basket), a four-way reversing valve 4 and a control system, wherein the four-way reversing valve 4 is used to control the reversing of the water flow of the heat exchange tube in the heat exchanger flow.

[0046] Such as Figure 2 to Figure 8 As shown, the shell 40 of the four-way reversing valve 4 is provided with four interfaces ABCD, wherein the A, B interfaces are respectively connected to the water inlet and the water outlet of the waterway, and the C, D interfaces are respectively connected to the water inlet and the water outlet of the heat exchange tube. The water outlet is connected.

[0047] The casing 40 is a rectangular box, and in the rectangular...

Abstract

Fully automatic pipe brush online cleaning system, including sliding brush assembly, four-way reversing valve and control system. Four ports, ABCD and ABCD, are arranged on the shell of the four-way reversing valve, of which the A and B ports are respectively connected to the water inlet and outlet The water port is connected, and the C and D ports are respectively connected to the water inlet and the water outlet of the heat exchange tube of the heat exchanger; the cavity inside the shell is provided with a switch that can realize the reversing of the water flow in the heat exchange tube through a simple operation of a cylinder. Reversing structure, the overall design of the reversing structure is simple, and the plugging effect is good. The four-way reversing valve has the advantages of simple and convenient operation, sensitive connection and blocking, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to a fully automatic tube brush online cleaning system, which belongs to the technical field of heat exchanger cleaning equipment. Background technique [0002] Heat exchanger is a widely used equipment in chemical industry and power field, its function is to transfer heat from hot fluid to cold fluid. Scaling of circulating cooling water heat exchangers is a common phenomenon. At present, the main method of cleaning the scaling of circulating cooling water heat exchangers is pipe brush cleaning, which is a relatively economical and economical cleaning method. The existing pipe brush cleaning device is shown in the Chinese invention patent "Authorized Announcement Number: CN 105758252 B, Authorized Announcement Date: 2017.10.31, Name: Fully Automatic Pipe Brush Online Cleaning System", which uses a four-way reversing valve to change the The water flow direction of the cooling water pipe of the heater is used to control the nylon ...
