Description
Technical field
The present invention relates to a kind of novel double-layer four-way change-over valve, belong to four-way change-over valve field.
Background technology
In industrial processes, having many uses of four-way change-over valve is general, at present, the one of employing in Regenerative Combustion System
As be dividing plate four-way change-over valve, it includes valve body, and valve body offers the relative first port in left and right, second port, Yi Jiqian
Afterwards relative to the 3rd port, the 4th port, be provided with the rotation dividing plate of changing flow direction in valve body, original state, rotate dividing plate by the
Single port, the 3rd port separate in the connection of both the same sides, and second port, the 4th port are separated in the connection of both opposite sides；
After rotation dividing plate rotates 90 °, rotate dividing plate by first port, the 4th port connection, by second port, the 3rd port connection.
In Regenerative Combustion System, the work process of four-way change-over valve is: gas flows into valve body from first port after being pressurizeed by aerator,
Valve body is flowed out in the 4th port through homonymy, after performance loop, flows back to valve body, then the second port from homonymy from the 3rd port
Flow back to air-introduced machine, form a complete loop；After rotation dividing plate rotates 90 °, fluid still flows into valve body from first port,
But change and flow out valve body from the 3rd port, after performance loop, flow back to valve body from the 4th port, then flow out valve from second port
Body, is eventually connected at air-introduced machine.Do not changing the situation that aerator is connected, air-introduced machine is connected with second port with first port
Under, change the gas flow of the performance loop being between the 3rd port and the 4th port.But, current four-way change-over valve
Switching direction by way of rotating dividing plate and rotating 90 °, it is easily caused gas leakage, reduces work efficiency, is particularly changing
To in the case of excessively frequently, the sealing member rotating between dividing plate and valve body can be worn quickly, lead to reveal more seriously, be
Solve this problem, need a kind of four-way change-over valve of better tightness badly.
