Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention Specific embodiment of the present utility model.
Embodiment 1 depressurizes current-limiting type elbow
As shown in Figs. 1-5, the utility model provides a kind of decompression current-limiting type elbow, including straight tube tube body 3 and bend pipe tube body 8,
The Single port of the straight tube tube body 3 is water inlet 1, is provided at the water inlet 1 into water partition 2, the water inlet Inlet through hole 9 is provided on partition 2, the diameter of the inlet through hole 9 is the 30%-60% into 2 diameter length of water partition.Water inlet every The diameter of plate 2 is equal with the intracavity diameter of straight tube tube body 3.
The other port of the straight tube tube body 3 is provided with decompressing baffle plate 4, and the decompressing baffle plate 4 is another with straight tube tube body 3 Single port is tightly connected to form dashpot.
One end on the straight tube tube body 3 close to decompressing baffle plate 4 is connected with bend pipe tube body 8, one end of the bend pipe tube body 8 Mouth is connect with straight tube tube body 3 and the another port of bend pipe tube body 8 is water outlet 5, and water outlet partition 6 is provided at the water outlet 5. Water outlet through-hole 10 is provided on the water outlet partition 6, the diameter of the water outlet through-hole 10 is the 30%- for being discharged 6 diameter length of partition 60%.The diameter for being discharged partition 6 is equal with the intracavity diameter of bend pipe tube body 8.
The thickness of the water inlet partition 2 is 1.3-1.6 times of 3 wall thickness of straight tube tube body, and the thickness of the water outlet partition 6 is curved 1.3-1.6 times of 8 wall thickness of pipe tube body, the thickness of the decompressing baffle plate 4 are 1.3-1.6 times of 3 wall thickness of straight tube tube body.The straight tube The wall thickness of tube body 3 is equal with the wall thickness of bend pipe tube body 8.
It is provided with locating piece 7 at the water inlet 1 of the straight tube tube body 3 and at the water outlet 5 of bend pipe tube body 8, it is described At least provided with 4 locating pieces 7 on straight tube tube body 3.At least provided with 4 locating pieces 7 on the bend pipe tube body 8.Pipe fitting carries out When machine tooling, the clamping on lathe of locating piece 7 is used, and processing efficiency can be improved, guarantee machining accuracy.
Wherein, it intakes partition 2 and water outlet partition 6 depressurizes and the effect of current limliting.
It, can be rapidly by stream since water inlet partition 2 reduces rapidly inner cavity when water flow is by water inlet partition 2 in pipeline Speed is under pressure drop, and at by water outlet partition 6, secondary current limliting can be by the pressure and reduced velocity flow of water flow after depressurizing.Because common The corner of bend pipe tools elbow all can be directly by the impact of water flow, and the flowing under condition of high voltage can be to the same of bend pipe tools Position carries out greater impact, and impact force is concentrated, and be easy to cause the damage of product, so increasing by a decompression in the nozzle end of pipe fitting Baffle 4, and the thickness of decompressing baffle plate 4 is thickeied, the position that impact force is concentrated carries out especially thickening and handles, and ensure that product Quality and service life.Fig. 6 is the force analysis view of product, is water inlet at A, the water impact after at A will be concentrated At B, pipe fitting then is being flowed out by water export at C, to complete the process of entire water flow decompression current limliting and steering.
The utility model solve existing product local location be hit power it is excessive and generate leak or product rupture danger Etc. security risks integrally reduce the internal pressure of elbow, change the stress position of elbow while by Internal current limit partition It sets, greatly promotes safety, extend the service life of elbow.
The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field The common knowledge of those of ordinary skill.The protection scope of the utility model is based on the contents of the claims, any to be based on this reality The equivalent transformation carried out with novel technical inspiration, is also within the protection scope of the utility model.
