Abstract
The invention relates to an improved rotary four-way fluid reversing valve, which comprises a valve body, a valve core and a driving device. The driving device is connected with a shaft on the valve core through a coupling I and a coupling II and drives the valve core to rotate. The improved rotary four-way fluid reversing valve is characterized in that the valve core is a cylinder with an I-shaped cross section. U-shaped grooves for installing sealing rings are arranged on the upper and the lower surfaces of the cylinder. When the valve core is installed in the valve body, the inner wall of the valve body squeezes the sealing rings to completely seal two parts of a hollow cavity of the valve body divided by the valve core. The improved rotary four-way fluid reversing valve provided by the invention is good in sealing performance, the conveying distance of a sample box is greatly prolonged and the conveying speed of the sample box is improved, and the improved rotary four-way fluid reversing valve is good in stability, simple in structure and simple to manufacture.
Description
Technical field
The present invention relates to be applied to the pneumatic pipe transportation art, relate to a kind of fluid reversing device, particularly relate to a kind of improved rotary four-way fluid selector valve with high leak tightness and high reliability.
Background technique
At present, the rotary type four-way fluid diverter valve of in the pneumatic pipe transporting system, using, its valve core structure is as shown in Figure 4, valve body is a cylindrical body, along having through hole on the axis, the selector valve of this structure exists the sealing of spool and valve body poor, mutually gas leakage between four cavitys, produce power loss, energy waste cause manifold pressure to descend, when pressurized air promotion sample box moves ahead, speed and the distance of the operation of sample box reduce greatly, the requirement of can not satisfy long distance, carrying fast.In addition, the analytic method curved surface job insecurity on the shaft coupling of existing rotary type four-way fluid diverter valve, manufacturing difficulty.
Summary of the invention
The object of the invention is to overcome the defective of above-mentioned prior art, a kind of good seal performance is provided, working stability is made simple improved rotary four-way fluid selector valve.
The objective of the invention is to realize by following technical proposals:
A kind of improved rotary four-way fluid selector valve, comprise valve body, spool and drive unit, described drive unit is connected by the axle of installing on shaft coupling I and shaft coupling II and the spool and drives valve core rotation, it is characterized in that: the cross section of described spool has " U " type groove that seal ring can be installed for the cylindrical body of " worker " font on its cylindrical body top and bottom.
The centre of the described spool both ends of the surface of winning in succession have the T-shape groove that special sealing ring can be installed, and described special sealing ring is the inboard T-shape boss that is provided with spool T-shape groove tabling.
The disc cam profile of described shaft coupling I is " heart " shape curve.
Improved rotary four-way fluid selector valve of the present invention has following technical characterstic:
1, spool design being become the cross section is the cylindrical structure of " worker " font, the simultaneously top and bottom of cylndrical surface processing " U " type groove, seal ring is packed in the above-mentioned groove, after spool is packed valve body into, the cavity inner wall extruding sealing circle of valve body, realize the each other fully sealing of two-part that the hollow cavity of valve body is cut apart by spool, can reach primary seal; The both ends of the surface of winning in succession in the centre of spool simultaneously processing T-shape groove is installed the T-shape Stamping Steel Ribbon in the T-shape groove, rolling, twisted phenomena appear in Stamping Steel Ribbon in the time of can preventing Spool rotating.Above-mentioned improvement can prolong 500～550 meters of the fed distance of sample box, and the motion speed of sample box is brought up to 10 meter per seconds by original 8 meter per seconds.
2, the present invention is designed to " heart " type curve with the disc cam on the shaft coupling I 6, can guarantee that 2 detecting switches only have a switch to be in the state of compression under normal circumstances, if it is simultaneously compacted 2 detecting switches to occur, then equipment will reach the Times fault, stops follow-up equipment to start." heart " type curve and detecting switch are used in combination, and testing signal is fed back to PLC, by PLC constantly condition monitoring are realized in the position of spool in the four-way fluid selector valve.
In sum, improved rotary four-way fluid selector valve good airproof performance of the present invention, the fed distance that can greatly prolong the sample box improves the motion speed of sample box, and good stability, simple in structure, make simple.

Embodiment
Below in conjunction with accompanying drawing structure of the present invention is described.
Improved rotary four-way fluid selector valve of the present invention mainly by valve body 1, be installed in the spool 2 in the valve body, the upper end cap 3 that is installed in valve body 1 two ends and lower end cap 4 and drive unit 5 forms.The inside of described valve body 1 is a cylinder type hollow cavity, and the hole I, hole II, hole III and the hole IV that communicate with hollow cavity are arranged on it, and these four holes are symmetrically distributed on the valve body.Described drive unit 5 is connected with the shaft coupling II by shaft coupling I 6 and is connected with the axle 9 installed on the spool 2 and is with movable valve plug 2 rotations.Improvements are: spool 2 is designed to the cross section for the cylindrical body of " worker " font, has " U " type groove on its upper and lower cylndrical surface, in the groove seal ring 8 can be installed.The centre of the spool processing T-shape groove on the both ends of the surface of winning in succession is installed in special sealing ring in the groove.Special sealing ring as shown in Figure 9, structure for its inboard be provided with can with the chimeric T-shape of T-shape groove on spool projection.Spool is packed into behind the valve body, and the cavity inner wall extruding special sealing ring of valve body is realized sealing.
Another improvements of the present invention are: the Disc Cams of Design on the shaft coupling I 6 is become " heart " shape curve.
