Problems solved by technology

The disadvantage of the prior art is that these sediments or pollutants present in the circulating heating water will put a lot of pressure on the sealing system, thereby increasing the wear and tear of the sealing system and shortening its service life
In addition, the combination of channel communication and channel mixing in the valves of the prior art is limited, and the ports used as outlets or inlets cannot be changed arbitrarily, which limits the function of the valve.

Embodiment Construction

[0029] Such as figure 1 Shown is a modular valve system under this embodiment. The modular valve system is a multi-way valve 9 comprising four ports 2 . In this embodiment, the four ports 2 include a first port 2a, a second port 2b, a third port 2c and a fourth port 2d. The four ports are mainly used for switching and mixing fluids. The multi-way valve 9 includes a valve body 1 . The valve body 1 is provided with two valve cores 3, namely a first valve core 3a and a second valve core 3b. Each spool 3 has at least one linear drive 4 and one axial sealing element 5 . Specifically, the first spool 3a has a linear drive 4a and a sealing element 5a, and the second spool 3b has a linear drive 4b and a sealing element 5b. The modular valve system of the present invention is not limited to figure 1 The four-way valve system shown can also be extended to a five-way valve system, a six-way valve system or other multi-way valve systems. Based on the above structure, the valve co...

Abstract

A modular valve system is configured as a multi-way valve (9) having a valve body (1) and at least four ports (2) for switching over between or mixing fluids. At least two valve cores (3) are arranged in the valve body (1). Each valve core (3) has at least one linear actuator (4) and one axially sealing seal element (5) movable by the actuator between two corresponding axially spaced seal seats (8). The valve system may be made modular by dividing the valve body (1) into modular sections with each section having one valve core.

Description

【Technical field】 [0001] The invention relates to a modular valve system, in particular to a modular valve system applicable to heating, ventilation or cooling systems. 【Background technique】 [0002] Patent No. JP11044369 provides a motor-driven four-way valve. The four-way valve has a rotatable valve cover inside, and the passage in the valve cover can be connected through the change of the angular position of the valve disc, so that the ports are connected. [0003] During the heating of the water, the water is easily contaminated by special additives such as minerals, sealing aids, sand and antifreeze preservatives, which can generate large amounts of sediment. The disadvantage of the prior art is that these sediments or pollutants present in the circulating heating water will exert great pressure on the sealing system, thereby increasing wear on the sealing system and shortening its service life. In addition, the combination of channel communication and channel mixing ...
