[model utility content]
The utility model is exactly at the deficiencies in the prior art, and a kind of multiple-way valve device is provided, and not only stream is simple, with low cost for this, and reliable and stable work, rate of fault are low.
The utility model is to adopt following technological scheme to realize above-mentioned purpose: a kind of multiple-way valve device, include valve body and be connected drive unit on the valve body, this valve body includes housing and is located at the interior spool of housing, this spool is connected with the Zhi Ganliu road with the trunk stream, it is characterized in that: this spool includes the moving valve gap that cooperatively interacts and decides valve gap, should be connected with drive unit by moving valve gap, and on moving valve gap, be provided with calibrating installation, should decide valve gap and fixedly connected, and decide to be provided with a main aperture that is communicated with the trunk stream and at least one hole that is communicated with the Zhi Ganliu road on the valve gap with housing.
As further specifying of such scheme: the speed reducer that described drive unit includes stepper motor and is connected with it is provided with flexible coupling between this speed reducer and the valve body.
Described to decide valve gap be cylindrical structure, and this is decided valve gap and is rotatably connected with moving valve gap is coaxial, is provided with the joint that at least one is connected with the Zhi Ganliu road on the cylinder of deciding valve gap or bottom surface.
Described Zhi Kongwei is located at and decides on valve gap and the face that moving valve gap cooperates, and the ring-shaped distributed hole of corresponding connection with joint.
Described main aperture is that this main aperture and each hole are equidistant along the hole of deciding the setting of valve gap medial axis.
Described moving valve gap is the circular block structure that is connected with coupling, moving valve gap with decide face that valve gap cooperates on, be provided with groove from the center of circle along its radius, this groove length is not less than main aperture and props up the distance in hole.
Described positioning device is for being located at the bolt on moving valve gap and the housing respectively.
Described moving valve gap is plane, sphere or the conical surface with the fitting surface of deciding valve gap.
The beneficial effect that the utility model adopts above technological scheme to reach is: spool of the present utility model is the valve gap of two coaxial cooperation, the trunk stream is distributed in the central position of deciding valve gap, the Zhi Ganliu road is distributed in around the trunk stream in the form of a ring, be communicated with trunk stream and Zhi Ganliu road by the groove on the moving valve gap again, therefore not only simple in structure, more Zhi Ganliu road can be set, and stream is clear, residual liquid is few, and reliable and stable work, rate of fault are low.
