Description
Technical field
The invention belongs to five-way valve field, more particularly, to a kind of mechanical type two position-5 way valve.
Background technology
At present, common five-way valve structure is " slide column type ", such as Chinese patent notification number：CN103016785A, discloses
A kind of symmetric two-position five-way valve, including valve body, may move the valve rod in the valve pocket A of valve body, located at the valve at valve body two ends
Lid, equidistant successively from left to right on described valve body wall is provided with interior air vent one, gas outlet one, air inlet, gas outlet two, interior row
QI KOU two；On described valve pocket A inwall, fixation is lined with spacer, and described spacer is interval with some flat circles, described each flat
Circle and interior air vent one, gas outlet one, air inlet, gas outlet two, interior air vent two is crisscross arranged, and described valve rod two ends are provided with work
Plug, valve rod is interval with two ventilation recesses, and described valve gap is provided with hand-operated valve, and described air inlet passes through logical located at valve body
Hole is connected with hand-operated valve, and described hand-operated valve is connected with valve pocket A.
However, in existing slide column type structure, when containing solid impurity in compressed air, impurity can be attached to spool face
Slide with valve element, during this, easily cut sealing ring, lead to cannot realize between sealing ring and valve element effectively sealing.When
When containing moisture in compressed air, moisture can wash away the oils and fatss on sealing ring, leads to slide construction work bad.Therefore existing
Two-way valve in technology is higher for the cleannes requirement of working media, otherwise will largely effect on the reliability of valve.
Content of the invention
The present invention is to overcome above-mentioned deficiency of the prior art, there is provided a kind of working media cleannes that reduce will
Seek, improve mechanical type two position-5 way valve of functional reliability.
To achieve these goals, the present invention employs the following technical solutions：
