Abstract
The utility model relates to a pipe union, which comprises an input end and an output end, wherein two end parts at the outer part of the whole pipe union are hex surfaces or external threads, and the middle part is a cylindrical surface; and the pipe union achieves the purposes of current limiting and pressure boosting by virtue of a aperture ratio of the inner bores of the input end and the output end. Through computing the aperture ratio of the inner bores of the input end and the output end of the pipe union as well as the angle of the bores in the inner conical surface, the flow control for a pipeline system can be realized; and if the hydraulic pressure of the pipeline system is required to be increased, the diameter of a connecting pipe at the output end can be changed. By adopting the pipe union, the pipeline system can perform the current limiting and pressure boosting functions without an additional flow limiting valve and an additional pressure boosting device, the cost is saved, the number of elements used in the pipeline system is reduced, and the risk of leakage is lowered.
Description
Technical field
The utility model belongs to mechanical manufacturing field, but the pipe joint of particularly a kind of automatic current limiting, supercharging.
Background technique
Pipe joint is requisite important components and parts in the various pipe-line systems, and pipe-line system is that various machinery (equipment) provide stable flow rate and ensured the hydraulic pressure of pipe-line system.The common tube joint can only play interconnect function, can satisfy different flow and hydraulic pressure in order to make pipe-line system, need in pipe-line system, increase components and parts such as flow-limiting valve and supercharging device usually, has therefore increased the risk that leakage takes place for cost and pipe-line system.
The model utility content
But the pipe joint that the technical problem that the utility model will solve provides a kind of automatic current limiting, supercharging and do not leak.
A kind of pipe joint is divided into input end and output terminal, and the outside two end part of whole pipe joint are hex surface, and the middle part is a periphery; Interior threaded hole, tool withdrawal groove, inner cone face are arranged in the inside of said input end, and tool withdrawal groove is between interior threaded hole and inner cone face; In the inside of output terminal tool withdrawal groove and interior threaded hole are arranged; The inside of input end and output terminal is communicated with by unthreaded hole, and an end of unthreaded hole connects the inner cone face, and the other end connects tool withdrawal groove.
A kind of pipe joint of external thread structure equally also is divided into input end and output terminal in addition, and the outside two end part of whole pipe joint are outside thread, and the middle part is a periphery; Unthreaded hole, inner cone face are arranged in the inside of input end; There is unthreaded hole inside at output terminal, and unthreaded hole runs through whole output terminal, and an end of unthreaded hole connects the inner cone face.
On the basis of above-mentioned two kinds of structures, the input end of pipe joint is 1, and output terminal can be 1～3.
Adopt the utility model in pipe-line system, need not increase the function that flow-limiting valve and supercharging device just can be realized current limliting and supercharging, practiced thrift cost, reduced the use of components and parts in the pipe-line system, reduced the risk of leakage.

Embodiment
The purpose of the utility model provides the pipe joint of ability automatic current limiting and supercharging.As shown in Figure 1, pipe joint is divided into input end 1 and output terminal 2, and the outside two end part of whole pipe joint are hex surface, and the middle part is a periphery.Interior threaded hole 3, tool withdrawal groove 4, inner cone face 5 are arranged in the inside of input end 1, and tool withdrawal groove 4 is between interior threaded hole 3 and inner cone face 5.Tool withdrawal groove 7 and interior threaded hole 8 are arranged in the inside of output terminal 2.The inside of input end 1 and output terminal 2 is communicated with by unthreaded hole 6, and an end of unthreaded hole 6 connects inner cone face 5, and the other end connects tool withdrawal groove 7.The aperture of input end 1 and output terminal 2 can freely be selected according to the needs of flow and pressure.
The structurally variable of aforementioned tube joint is changed to the male connector structure; That is to say to change the position of hex surface into outside thread that as shown in Figure 2, the pipe joint of external thread structure equally also is divided into input end 1 and output terminal 2; The outside two end part of whole pipe joint are outside thread, and the middle part is a periphery.Unthreaded hole 9, inner cone face 5 are arranged in the inside of input end 1.In the inside of output terminal 2 unthreaded hole 10 is arranged, unthreaded hole 10 runs through whole output terminal 2, and an end of unthreaded hole 10 connects inner cone face 5.The aperture of input end 1 and output terminal 2 can freely be selected according to the needs of flow and pressure.
The structure of aforementioned tube joint is also variable on the basis of above two kinds of structures to be changed to 1 input end, 1～3 output terminal, and other structure is constant.
The utility model pipe joint is on the basis of common tube joint, to improve, and utilizes the endoporus aperture of pipe joint input end 1 and output terminal 2 recently to realize the purpose of current limliting and supercharging.The control to the pipe-line system flow is realized in endoporus aperture through designing and calculating pipe joint input end 1 and the output terminal 2 when angle of inner cone face, and the hydraulic pressure that increases pipe-line system like needs also needs carry out reducing to output terminal 2 connecting tubes.The utility model is applicable to various pipe joints.
The utility model is simple in structure, be easy to produce, effect is safe and reliable, on the basis that does not increase flow-limiting valve and supercharging device, can adjust flow and pressure as required, has good economic benefits and use value.
