Abstract
The invention relates to a three-way change valve which comprises a valve body, wherein the valve body is provided with an inlet, a first outlet and a second outlet. The three-way change valve provided by the invention is characterized in that a wear-resisting base plate is connected with the inner ports of the first outlet and second outlet of the valve body; an opening communicated with the first outlet and second outlet of the valve body is formed on the base plate; in addition, a spindle mounting hole internally provided with a spindle is formed on the base plate, a connecting rod is arranged at the spindle, and one end of the connecting rod is connected with a wear-resisting reversing plate; a driving lever connected with a cylinder through a gearing is connected with one end of the spindle; and a spring the periphery of which is provided with a feed end cap is sleeved at the other end of the spindle, the feed end cap is connected with the valve body through a sealing element. The three-way directional control valve has the advantages of simple structure, convenience in installation, high tightness and abrasive resistance.
Description
Technical field
The present invention relates to the valve arrangement field, relate in particular to a kind of strength conveying three-way diverter valve.
Background technique
Ball valve is that the three-way diverter valve that ends commonly used is gone up in industry, and the sealing configuration of ball valve has very big influence to its usability.As shown in Figure 1; Existing strength is carried and is generally the ball valve pattern with three-way diverter valve; Constitute by spool 101 and the valve body 102 that is provided with three runners; Spool 101 is located at the inside of valve body 102, and the selector valve of this structure has simple in structure, the characteristics that standardization level is high; But when using and carrying material for a long time with chiseling property of mill; Material can make ball valve seal produce wearing and tearing, causes gas leakage and batch mixing phenomenon, reduction of service life.
Summary of the invention
The applicant provides strength a kind of simple in structure, easy for installation to carry and uses three-way diverter valve to the above-mentioned shortcoming of existing triplet commutation valve arrangement, and it has higher sealing and wear resistance.
The technological scheme that the present invention adopted is following:
A kind of three-way diverter valve; Comprise valve body; Valve body has import and first outlet and second outlet; On the inner port of valve body first outlet and second outlet, be connected with wear-resisting backing plate; Have on the backing plate and valve body first outlet and the perforate that second outlet communicates, on backing plate, also have the rotating shaft mounting hole, device has rotating shaft in the rotating shaft mounting hole; Install connecting rod in the rotating shaft, connect wear-resisting reversing plate at an end of connecting rod; End in rotating shaft connects driving lever, and driving lever is connected with cylinder through transmission device.The other end in rotating shaft is with spring, the peripheral unit charging end cap of spring, and the charging end cap is connected with valve body through Sealing.
It is further characterized in that:
In the import of valve body and first outlet and second outlet) install anti-wearing liner respectively;
Said lining adopts high manganese steel material.
Beneficial effect of the present invention is following:
Through wear-resisting backing plate of device and wear-resisting reversing plate in valve body; And drive the high reversing plate of tightness through transmission device and carry out the commutation of runner; Solved prior art and produced the problem that wearing and tearing cause sealing to descend at the long-time back Sealing that uses; Improve the wear resistance and the sealing of spool, reduced gas leakage and batch mixing phenomenon; At the import and the outlet port device high abrasion lining of valve body, further improve wear resistance simultaneously, prolonged the working life of valve.

Fig. 2 is a sectional view of the present invention.
Fig. 3 is the sectional view along the A-A cross-wise direction of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 2; The present invention includes valve body 4; Valve body 4 has import 4-3 and the first outlet 4-1 and the second outlet 4-2; Device anti-wearing liner 5 in import 4-3 and the first outlet 4-1 and the second outlet 4-2; Lining 5 adopts high manganese steel material to make; Improve the wear resistance that valve body 4 is imported and exported, prolonged the working life of valve body 4.On the inner port of the valve body first outlet 4-1 and the second outlet 4-2, be connected with wear-resisting backing plate 6; Have the perforate that communicates with the second outlet 4-2 with the valve body first outlet 4-1 on the backing plate 6; On backing plate 6, also have the rotating shaft mounting hole, device has rotating shaft 15 in the rotating shaft mounting hole.As shown in Figure 3, device connecting rod 9 in the rotating shaft 15 connects reversing plates 8 at an end of connecting rod 9 through pin 13, connects driving lever 7 at an end of rotating shaft 15 through key, and the other end is with spring 11 and installs locking nut 10.The pressure of spring 11 has determined the tight degree of sealing of reversing plate 8, through adjusting the size that locking nut 10 can change spring 11 pressure, increases the sealing of 8 pairs of outlets of reversing plate with this, reduces gas leakage, and is safe and reliable.At the peripheral unit charging end cap 12 of spring 11, charging end cap 12 is connected with valve body 4 through Sealing 16-1.Be connected with valve body 4 through Sealing 16-2 with discharging end cap 12-1 between the driving lever 7 at connecting rod 9.Wear-resisting backing plate 6 and reversing plate 8 adopt high abrasion resisting material to make (for example high manganese steel material).
Like Fig. 2, shown in Figure 3; In the working procedure; Be connected in cylinder 2 work of cylinder block 3 through pin 1 after, the piston rod of cylinder 2 is connected with drive link 14 through crank, drives drive link 14 and driving lever 7 work; Rotating shaft 15 is rotated; Drivening rod 9 makes reversing plate 8 accomplish commutation, and the commutation angle of reversing plate 8 between the first outlet 4-1 and the second outlet 4-2 is 45 °; Seal up the first outlet 4-1 or the second outlet 4-2 that are connected with wearing plate 6 after commutation is accomplished, realized the commutation course of conveying of material.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of basic structure of the present invention, the present invention can do any type of modification.
