Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as image 3 As shown, a reciprocating three-way valve driven by differential pressure includes a valve body 4, and a straight flow channel 6 is arranged inside the valve body 4, and the two ends and the middle part of the straight flow channel 6 communicate with three joints 1 respectively. Set on the valve body 4 (the joint 1 and the valve body 4 adopt one or several combinations of connection methods such as threaded connection, flange connection, welding, etc., and a seal 2 can also be set between the joint 1 and the valve body 4), There is a spool 3 inside the linear flow channel 6 (the spool 3 is metal or non-metallic material with anti-corrosion effect), there is a gap between the spool 3 and the inner wall of the linear flow channel 6, and the spool 3 is in the fluid medium (fluid medium Under the action of liquid or gas), the sealin...

Abstract

The invention relates to a differential pressure-driven reciprocating three-way valve which comprises a valve body. A linear flow channel is arranged in the valve body, the two ends and the middle of the linear flow channel are communicated with three joints respectively, the joints are arranged on the valve body, a valve element is arranged in the linear flow channel, and a gap is formed between the valve element and the inner wall of the linear flow channel; the valve element can press and seal the sealing faces of the joints arranged at the two ends of the linear flow channel under the action of a fluid medium, cannot be disengaged from the joint arranged in the middle of the linear flow channel and cannot seal the joint arranged in the middle of the linear flow channel. According to the differential pressure-driven reciprocating three-way valve, the structure is simple, the manufacture cost is low, the differential pressure of the fluid medium is adopted as a driving source, and automatic allocation of the ports can be achieved.

Description

technical field [0001] The invention belongs to the field of valves, in particular to a reciprocating three-way valve driven by differential pressure. Background technique [0002] The body of the three-way valve has three ports. When the internal valve core is in different positions, the opening or closing of different ports can be adjusted to realize diversion (one in and two out), confluence (two in and one out) or flow direction switching ( One in and one out). The position change of the spool needs to be manually driven by external force, that is, the spool extends out of the valve seat through the connecting piece, and the connecting piece is manually manipulated to drive the spool to rotate, and the spool rotates to different positions to open or block the corresponding port. Since the spool transmits external force to the spool to drive the spool to rotate through mechanical transmission, the structure of the spool and the valve seat of the three-way valve are relat...
