Abstract
The utility model belongs to the technical field of nuclear fuel elements, particularly relates to a three-way change valve, and aims to solve the technical problem about providing a three-way change valve, which reduces the abrasion of a switch, improves the reliability and the service life, and guarantees the flow direction of high temperature powder materials. The three-way change valve comprises a valve body (1), supports (2), blank covers(3), a valve core (4), bearings (5) and end covers (6), wherein the valve core (4) is arranged in the valve body (1); the end covers (6) are fixed on the valve body (1) through bolts; the supports (2) are fixed on the outer sides of the end covers (6); the bearings (5) are arranged in the supports (2); and the bearings (5) are sealed by the blank covers (3). The utility model has the benefits that three-way change valve can be used in the dry process production; the high temperature powder materials flow fast; the effect of no residue is realized; the change of direction is stable and reliable; the abrasion of the switch is reduced; the reliability of operation is high; and the service life is long.
Description
Technical field
The invention belongs to the nuclear fuel component technical field, be specifically related to a kind of three-way diverter valve.
Background technique
Three-way diverter valve, be widely used in fields such as flue gas on petrochemical industry, power station vent gas treatment and the heat accumulating type Industrial Stoves and air commutation, existing common three-way diverter valve physical size is different, spool is sphere or plunger, general runner is " L " shape or "T"-shaped runner, influence passing ability with respect to gas or liquid that can not, carry but can not be used for powder.Because the particularity by medium makes common selector valve be difficult to overcome problems such as smooth flow, is designed to " Y " shape structure thus, spool is commutation about tile is easier to realize.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned deficiency, to provide a kind of reduction switch wearing and tearing, raising reliability and operating life, a kind of three-way diverter valve of assurance high-temperature dust end logistics direction.
The technical solution adopted in the present invention is:
A kind of three-way diverter valve wherein, comprises valve body, bearing, stifle, spool, bearing and end cap, and wherein spool is located in the valve body, and end cap rolls by bolt and fixes on the valve body, and bearing is provided with bearing by being bolted to the end cap outside in the bearing, and the bearing envelope has stifle.
Aforesaid a kind of three-way diverter valve, wherein, described three-way diverter valve is designed to " Y " shape structure, comprising a material inlet and two material outlets.
Aforesaid a kind of three-way diverter valve, wherein, described valve core structure is tile, the smooth surface arc transition.
The invention has the beneficial effects as follows:
1. can apply in the dry production the rapid noresidue of high temperature powder Flow of Goods and Materials;
2. it is reliable and stable to commutate;
3. reduce the switch wearing and tearing, operational reliability height, long working life.
Description of drawings
Fig. 1 is the three-way diverter valve structural representation;
Fig. 2 is the valve body schematic representation;
Fig. 3 is the spool schematic representation.
Among the figure: 1. valve body, 2. bearing, 3. stifle, 4. spool, 5. bearing, 6. end cap.
Embodiment
Below in conjunction with drawings and Examples a kind of three-way diverter valve provided by the invention is introduced:
As shown in Figure 1, a kind of three-way diverter valve, wherein, comprise valve body 1, bearing 2, stifle 3, spool 4, bearing 5 and end cap 6, wherein spool 4 is located in the valve body 1, and end cap 6 rolls by bolt and fixes on the valve body 1, and bearing 2 is by being bolted to end cap 6 outsides, be provided with bearing 5 in the bearing 2, bearing 5 envelopes have stifle 6.
As shown in Figure 2, described three-way diverter valve is designed to " Y " shape structure, comprising a material inlet and two material outlets, in the work, by switching commutation about the realization of control valve core rotation;
When (1) needing material to lead to left side container, material enters from upper entrance, this moment spool guarantee " outlet 1 " unimpeded and " outlet 2 " close;
(2) when needs lead to right side container joint, control system is tangentially given pneumoelectric Effector signal, the action of electromagnetic valve double-acting cylinder turns clockwise, make spool rotate former exit end face and become the charging end face, former charging end face becomes the discharge port of " outlet 2 ", " export 1 " at this moment and close, material flows to right side container by the spool smooth surface;
(3) when the needs material leads to left side container again, only need tangential control, spool rotates back to original position more counterclockwise and gets final product.
As shown in Figure 3, described valve core structure is tile, the smooth surface arc transition, and defeated material passage is smoothly bright and clean, guarantees that the fluid circulation is smooth and easy, the resistance minimum, perfect air-operated control device can improve automatization level, guarantees operational reliability efficiently.
This valve adopts vertical left and right sides Twin channel to arrange, top is material feeding mouth, spool and valve body adopt plane sealing, selector valve is controlled double-acting cylinder by two-position-five-way solenoid valve, adopt compressed air-driven, realize the solenoid valve action by the contactor control circuit, and detected by two position detecting switchs respectively, magnetic switch is directly installed on above the cylinder, commutate by switching about the realization of control valve core rotation during the valve proper functioning, reach about powder follow procedure input and check hopper, thereby realize the commutation of selector valve.
Claims (3)
1. three-way diverter valve, it is characterized in that: comprise valve body (1), bearing (2), stifle (3), spool (4), bearing (5) and end cap (6), wherein spool (4) is located in the valve body (1), end cap (6) is by being bolted on the valve body (1), bearing (2) is by being bolted to end cap (6) outside, be provided with bearing (5) in the bearing (2), bearing (5) envelope has stifle (6).
2. a kind of three-way diverter valve according to claim 1, it is characterized in that: described three-way diverter valve is designed to " Y " shape structure, comprising a material inlet and two material outlets.
