Embodiment Construction

[0008] The implementation of the present invention is as follows, as explained below in conjunction with the accompanying drawings, the time-sharing switching three-position four-way valve of the present invention is mainly composed of a water inlet tank 1, a reversing wheel 2, a fixed wheel 3, a driving wheel 4, a casing 5, a driver 6, The water inlet and outlet 7, the water outlet 8, the sealing ring 9, and the sealing ring 30 are composed of the water inlet 1 and the water outlet 8. The structure is the same, but there is a 90° corner difference during installation. The box body 5 prevents debris from entering the valve body Inside, sealing ring 9 and sealing ring 30 prevent system water from flowing out of the valve body during the reversing conversion process. Its working principle is that at the beginning, the plate holes 12, 17, 18, 23, 26 in the device are concentric, and the plate holes 25, 22, 21, 16, 15 are concentric, and the hot water of the system enters the water...

Abstract

The invention relates to a time-sharing switching three-position four-way valve applied to a heating system. The device mainly comprises a water inlet tank (1), reverse wheels (2), a fixed wheel (3), a driving wheel (4), a box body (5), driving devices (6), a water inlet and outlet port (7), a water outlet tank (8), a seal ring (9) and a seal ring (30). The driving devices (6) drive the driving wheels (4) to drive the reverse wheel (2) to rotate, so that plate holes on the reverse wheels (2) stay in different positions, and the purpose of switching between feed water and return water is achieved. When a certain driving device (6) operates, the plate holes of the two reverse wheels (2) are not concentric, and the function of cut-off can be exerted. Because the plate holes of the device have the same aperture, the device does not have any pressure loss after switching is completed.

Description

technical field [0001] The invention relates to a valve on a pipeline, which is a three-position four-way valve device capable of time-sharing switching. The device is suitable for a heating system, especially a heating system with hydraulic imbalance. Background technique [0002] In the heating season, due to the unbalanced hydraulic power of the heating system of the existing building, the heat supply of the users is not uniform. The temperature and temperature difference also change accordingly, causing the power (or system resistance) of the natural circulation of the building system to also change, which further aggravates the hydraulic imbalance of the heating system. [0003] For the above problems, there is no better technical solution to solve the problem at present. Contents of the invention [0004] The purpose of the present invention is to provide a time-sharing switching three-position four-way valve. The device is installed in the pipe well of the househol...
