Description

A kind of threeway of regulating flow quantity

Technical field

The utility model is specifically related to conduit coupling field, relates more specifically to a kind of threeway of regulating flow quantity.

Background technology

Threeway is mainly used for changing flow direction, be wanted at branched pipe used in main pipeline as important conduit coupling. It can classify by pipe diameter size.Threeway is that there are three branch pipe, i.e. an import, two outlets for tool;Or two imports, one outlet A kind of chemical industry pipe fitting, have T shapes and Y shape, there is isometrical nozzle, also there is reducing nozzle, collect for three identical or different pipelines Place.

Traditional threeway can only be used for changing flow direction, cannot generally change flow of the fluid in threeway, to change The flow for becoming fluid Jing Guo threeway, needs to increase valve part before threeway, and liquid of the change Jing Guo threeway is realized with this The flow of body can be such that cost increases in this way, while limit the application of threeway.

Utility model content

To solve the problems, such as that threeway in the prior art can not adjust flow, the utility model provides a kind of regulating flow quantity Threeway.

The utility model adopts the following technical solution：A kind of threeway of regulating flow quantity, the threeway include first, the Two, the first, second, third branch pipe inner tube is respectively set in first, second, third pipe shell in third branch pipe shell；Institute It states first, second, third pipe shell to be connected through a screw thread with the first, second, third branch pipe inner tube respectively, first branch pipe The length of inner tube is more than the length of first pipe shell；The length of the second branch pipe inner tube is more than outside second branch pipe The length of shell；The length of the third branch pipe inner tube is more than the length of the third branch pipe shell.

The first, second, third sieve is respectively set in the first, second, third branch pipe inner tube pipe.

The mesh size of first, second, third sieve successively decreases successively.

The first, second, third hand rest is respectively set in the first, second, third branch pipe outer casing end.

The length of first, second, third hand rest is successively decreased successively.

The utility model is improved by the structure to threeway, and specially set threeway to inner tube passes through spiral shell with shell The form of line connection, the length of inner tube are more than the length of shell, can be by by inner tube precession enclosure, and then make inside threeway Intersection narrows, and then plays the purpose for adjusting fluid flow.

Specific implementation mode

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

With reference to attached drawing, a kind of threeway of regulating flow quantity, the threeway include first, second, third pipe shell 1,2, 3, the first, second, third branch pipe inner tube 4,5,6 is respectively set in first, second, third pipe shell 1,2,3；I.e. first First branch pipe inner tube 4 is set in branch pipe shell 1；Second branch pipe inner tube 5 is set in second pipe shell 2；In third branch pipe shell 3 Second branch pipe inner tube 6 is set；First, second, third branch pipe inner tube, 4,5,6 outer wall is threaded 13；And by the screw thread 13 with First, second, third pipe shell 1,2,3 is separately connected；The length of the first branch pipe inner tube 4 is more than outside first branch pipe The length of shell 1；The length of the second branch pipe inner tube 5 is more than the length of second pipe shell 2；The third branch pipe inner tube 6 length is more than the length of the third branch pipe shell 3；The part that the branch pipe inner tube stretches out branch pipe shell passes through screw thread and its He is threadedly coupled component.First, second, third branch pipe inner tube, 4,5,6 outer wall is respectively provided with screw thread.

When needing to adjust three-way flowrate, by the branch pipe inner tube precession threeway confluence 14 of threeway entrance；Due to This branch pipe inner tube has part to stretch into inside threeway confluence, plays the role of controlling flow to flowing into the fluid in threeway.

The first, second, third sieve 7,8,9 is respectively set in first, second, third branch pipe inner tube, 4,5,6 pipe.The sieve Net is fixedly connected in branch pipe inner tube；In the sieve of branch pipe inner tube setting filtering can be effectively played when containing impurity in fluid Effect.Said inner tube is connect with outer casing screw, can be by inner tube out of shell when product has impurity in threeway intersection or sieve It screws out, it is easy to clean.

The mesh size of first, second, third sieve 7,8,9 successively decreases successively.The mesh of i.e. described first sieve Size is more than the mesh of the second sieve, and the mesh of second sieve is more than the mesh of third sieve.Mesh is big in three sieves Small different setting, when in fluid, there are when the impurity of different-grain diameter, gradient filtration can be played the role of to impurity；Further Ground, the branch pipe for selecting sieve mesh small are inlet tube, and screening effect is even more ideal.The size of the mesh of first sieve is 1mm；The size of the mesh of second sieve is 0.6mm；The size of the mesh of the third sieve is 0.5mm.

First, second, third pipe shell, 1,2,3 end be respectively set the first, second, third hand rest 10,11, 12；The hand rest is wrapped in one, second, third 1,2,3 end of branch pipe shell；The material of threeway be carbon steel, cast steel, steel alloy, The setting of stainless steel, copper, aluminium alloy etc., hand rest makes tee branch inner tube be not easy to skid when spinning in and out.

The length of first, second, third hand rest 10,11,12 is successively decreased successively.First, second, third sieve 7, 8,9 mesh size successively decreases successively, and the apparent length relative size of hand rest can intuitively show the opposite of sieve in the branch pipe Size, convenient for distinguishing.
