Abstract
The utility model relates to a rotary four-way fluid switching valve, which comprises a valve body. The interior of the valve body is a cylindrical hollow cavity, and the circumference of the cylindrical hollow cavity is provided with four holes which are communicated with the hollow cavity. A partition plate which divides the holes into two parts is arranged in the valve body, and is connected with a drive device through a shaft and a shaft coupler. The upper and the lower end covers seal the valve body, and are used for installing a positioning shaft, and the upper end cover is orderly fixed with a supporting base and a seat body of the drive device which is arranged on the seat body of the drive device. The rotary four-way fluid switching valve of the utility model has the characteristics that the resistance to the fluid is little, the structure is simple, the machining precision is low, and the utility model can be connected with various drive devices.
Description
Technical field
The utility model relates to a kind of fluid reversing device, particularly relates to a kind of rotary type four-way fluid diverter valve.
Background technique
At present, known four-way fluid selector valve is made up of valve body, spool, end cap and straight line mobile drive deivce, and four holes are arranged on the valve body, and circular trough is arranged on the spool, drive spool by the straight line mobile drive deivce and move around, reach communicating in twos of respective aperture on the valve body.But this complex structure requires the machining accuracy height, makes difficulty.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, provides a kind of resistance coefficient rotary type four-way fluid diverter valve little, simple in structure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rotary type four-way fluid diverter valve, comprise valve body, the inside of described valve body is a cylinder type hollow cavity, have four holes that communicate with hollow cavity around it, be provided with dividing plate in the valve body, described dividing plate is divided into two-part with hollow cavity and hole, and links to each other with drive unit by axle and coupling; Upper and lower end cap is with valve seal and be used for installation, positioning shaft, is fixed with bearing and drive unit pedestal on the upper end cap successively, and drive unit is installed on the drive unit pedestal;
Be connected with detecting switch on the described bearing;
Described drive unit can be reducing motor, retarding braking motor, electric pushrod, cylinder or oil cylinder.
Rotary type four-way fluid diverter valve of the present utility model, simple in structure, be convenient to processing, and the resistance of convection cell is little.
