Description
Technical field
The present invention relates to a kind of novel double-layer four-way reversing valves, belong to four-way reversing valve field.
Background technology
In industrial processes, having many uses for four-way reversing valve is general, currently, used in Regenerative Combustion System one
As be partition board four-way reversing valve, it includes valve body, and the opposite first port in left and right, second port, Yi Jiqian are offered on valve body
Opposite third port, the 4th port afterwards, are equipped with the rotation partition board of changing flow direction in valve body, original state, and rotation partition board is by the
Single port, third port separate to be connected in both the same sides, and second port, the 4th port are separated and are connected in both other sides；
After rotation partition board is rotated by 90 °, first port, the 4th port are connected to by rotation partition board, and second port, third port are connected to.
In Regenerative Combustion System, the course of work of four-way reversing valve is：Gas pressurizeed by air blower after from first port flow into valve body,
The 4th port outflow valve body through homonymy flows back to valve body, then the second port from homonymy after performance loop from third port
Air-introduced machine is flowed back to, a complete circuit is formed；After rotation partition board is rotated by 90 °, fluid still flows into valve body from first port,
But change from third port and flow out valve body, after performance loop, valve body is flowed back to from the 4th port, then valve is flowed out from second port
Body is eventually connected at air-introduced machine.Do not changing the case where air blower is connect with first port, air-introduced machine and second port connect
Under, change the gas flow for the performance loop being between third port and the 4th port.But current four-way reversing valve
The switching direction by way of rotating partition board and being rotated by 90 °, it is easy to cause gas leakage, reduces working efficiency, is especially changing
To in the case of excessively frequent, the sealing element rotated between partition board and valve body can be worn quickly, cause to reveal more serious, be
Solve the problems, such as this, there is an urgent need for a kind of four-way reversing valve of better tightness.
