Description

Fluid multi-way reversing device

Affiliated technical field

The utility model relates to a kind of fluid delivery system fluid multi-way reversing device.

Technical background

At present,,, often need be transported to another place to fluid from one, also need to change a plurality of throughput directions sometimes, still, not need by conveyance fluid in order to satisfy the requirement of process conditions in Chemical Manufacture or in sewage disposal system.Usually a plurality of throughput directions of control need a plurality of common valves, and fluid need overcome the resistance of various pipelines, elbow, valve etc. and consume certain energy, and flow velocity is carried in influence, and operation is difficulty relatively, and pipeline connects complicated, installation cost is higher, and rate of breakdown is also corresponding to be increased.

In addition, common valve must possess certain ability of bearing the medium internal pressure, and will have enough strength and stiffness, and explosion does not take place to guarantee long-term the use.Internal pressure is that the sealability by valve guarantees, thereby valve must have reliable sealing performance again.So, the demanding strict technology of common valve, the processing technology complexity, manufacture cost is higher.

Summary of the invention

In order to overcome existing fluid delivery system fluid reversing because of adopting a series of difficulties that common valve brought, the utility model provides a kind of fluid multi-way reversing device, not only can substitute five common valves, devices such as pipeline, elbow have been saved, reduced installation cost, and, make easy and simple to handlely, rate of breakdown is low.Again because do not require that according to a process conditions needs conversion throughput direction so this fluid multi-way reversing device technical requirements is significantly less than common valve, manufacture technology is simple by fluid in the fluid delivery process.

The technological scheme that the utility model technical solution problem is adopted is:

On fluid multi-way reversing device housing, five interfaces are set, vertical uniform four rectangular windows on the housing inner chamber truncated cone type sealing surface, front window is corresponding with front port, rear hatch is corresponding with rear port, right window is corresponding with right interface, left window is corresponding with left interface, core body is connected with mandrel by fixing pin, and in the housing of packing into, cover plate is enclosed within on the mandrel, mandrel is connected with housing by Sealing, pressing plate is installed on mandrel in order, spring, pressing plate, bearing, lid, lid is connected with cover plate, and lid is connected with housing, handle is installed in the mandrel upper end, set five on the handle dextrorotation veer, one 0 °, two 45 °, three 90 °, four 270 °, five 360 °, the lower channel of core body is connected with the lower interface of housing, the upper channel of core body is connected with the mount inlet of housing, the right interface that left passage that is provided with on the core body and right passage and housing inner chamber are provided with, left side interface is to being connected into fluid supplying passage; Perhaps the front port of housing inner chamber setting, rear port are to being connected into fluid supplying passage.Vertical uniform two oblong channels on the core body truncated cone type sealing surface, left passage and right passage, the lower channel that the core body lower end is provided with is connected with left passage, and the upper channel that the core body upper end is provided with is connected with right passage.Spring is housed on the mandrel, and spring pressure is combined closely the frusto-conical surface of open-shut device core body and the frusto-conical surface of housing inner chamber, plays the anti-interior effect of leaking of sealing.The mandrel installed thrust bearing on spring capping top makes the keying moment of commutator reduce flexible and convenient operation to reduce to support the frictional force at position.

Housing, core material are metal, high-molecular polymer alloy.
