Abstract
The utility model comprises a Y-shaped three-way pipeline, wherein, one pipe is connected with the inlet pipe of material flow; the outlet positions of the other two outlet pipelines are provided with valve plates; the two valve plates which form an angle are fixed on a support frame; the connecting support frames of the two valve plates can rotate around a pin shaft; when one valve plate covers and seals one outlet pipeline, the other pipe is connected with the inlet pipe of the material flow. The utility model is characterized in that the two valve plates are conical valve plates; valve seats corresponding to the valve plates are arranged at the port of the outlet pipeline; the casing of the pipeline is formed by welding with steel plates; an inner valve and the valve seats adopt cast-iron structures; the surface, of the valve, which contacts the valve seats is provided with sealing rubber.
Description
The utility model relates to the three-way device that switches the mass transport passage.
Conveying powdered or granular material need use three-way device that the flow direction of logistics is switched and distribute in pipeline, as be used for the line transportation of thermal power plant electric precipitation bottom to pulverized fuel ash, also be used to carry external diameters such as grain, cement, mineral, building materials to be not more than the material of 50mm.Existing three-way device is the Y-piece road, wherein a pipe is connected with the inlet tube of logistics, the outlet port of other two outlet pipelines is equipped with a valve plate, two valve plates fix at an angle, the joint of two valve plates can rotate around a bearing pin, when a valve plate covered and seal an outlet conduit, the valve plate on another pipeline was in the position that is opened, to reach the purpose of distributing in the mass transport.Yet this type of three-way valve switches the flow direction of material by the swing of valve plate, because wobble plate is motion repeatedly often, cause that wearing and tearing are big, simultaneously, make integral weld forming owing to adopt sheet metal, make maintenance difficult, prolonged and repeated expands with heat and contract with cold, and causes steel plate deformed, closes to seal, and start difficult, adding that pulverized fuel ash is inhaled by negative pressure send, and is easy to generate the string ash, therefore, up to the present, to carry the three-way device of pulverized fuel ash be that the threeway grey valve that falls all has in various degree leakage ash in domestic all being used to.And because very difficulty in continuous operation, is repaired or changed to equipment.
The purpose of this utility model provides a kind of good seal performance, can use reliably and with long-term, and is not yielding, conveyance conduit three-way device simple in structure.All the other purposes of the present utility model are listed in specification in addition.
The purpose of this utility model is achieved in that and comprises a Y-type three way type pipeline, wherein a pipe is connected with the inlet tube of logistics, the outlet port of other two outlet pipelines is equipped with a valve plate, two valve plates at an angle and be fixed on the support, the connection support of two valve plates can rotate around a bearing pin, another pipe is connected with the inlet tube of logistics when a valve plate covers and seal an outlet conduit, it is characterized in that described two valve plates are the taper valve plate, be provided with and the corresponding valve seat of valve plate at the outer pipe road junction, conduit enclosure adopts the steel plate welding forming, internal valves and valve seat adopt the cast iron structure, are being provided with caulking gum with the contacted valve surface of valve seat.
Characteristics of the present utility model are: sealing is tight reliable, guarantee not have and leak, good thermal stability, not yielding, be particularly suited for carrying the pulverized fuel ash of high temperature, middle spool can turn round flexibly, and starting torque is little, can adopt working methods such as manual, pneumatic, electronic equally on the Starting mode, can control automatically equally.And the three-way valve structure of this valve and routine also has other difference.1. split type, but demolition.2. adopt the cone valve sealing.3. the outside can be provided with access opening, can check and change easily damaged parts.
The utility model is described in further detail below in conjunction with accompanying drawing with by embodiment:
Fig. 1 is an internal structure schematic representation of the present utility model
Fig. 2 is a form structure schematic representation of the present utility model
As shown in the figure, casing 1 is welded with steel plate, form pipe joint, valve seat 13 and valve plate all make cylinder iron or cast steel is made, and valve plate is fixed on the bearing pin 16 by last press table, the outside of valve plate clads resistant to elevated temperatures rubber 14 and is used for and valve base sealing, two valve plates coincide and are fixedly connected on the V-type support 15, and the outer rim of two valve plates is made the conical surface, and an also available block casting iron plate forms conical surface, the V-type angle is got the 20-50 degree, generally gets 45 degree.The end points of support rotates around a bearing pin 12, connect a rocker handle 11 from support, this rocker handle can manually or with electric pushrod 9 or air-leg be connected, thereby drive the sealing station that two valves are in different outlets respectively, the left side of pipeline exported sealed right pipe outlet conveying material when handle moved to left, on the contrary left line transportation material.
Observe for convenience and maintenance, be provided with hand hole 3 above corresponding valve plate on the shell, securing cover plate 2 on the hand hole.
Valve seat is made a clinoplain, and promptly edge height, middle low needs only the conversion that mobile small distance is promptly finished the threeway conveyance conduit like this.
Claims (4)
1. three-way device, comprise a Y-type three way type conduit enclosure, wherein a pipe is connected with the inlet tube of logistics, the outlet port of other two outlet pipelines is equipped with a valve plate, two valve plates at angle and be fixed on the support, two valve plates rotate around a bearing pin, it is characterized in that described two valve plates are the taper valve plate, be provided with the valve seat corresponding at the outlet conduit place, be provided with caulking gum with the contacted valve plate of valve seat surface with valve plate.
2. by the described three-way device of claim 1, it is characterized in that the support of fixing with valve plate is the V-type support, the V-type angle is got 45 degree.
