Description

Pipe joint element for various pipeline

The utility model system is relevant with joint, more detailed it, refer to a kind of various pipe joint elements that are suitable for especially, it makes connecting moves easily simple and firm, and prolongation pipeline life-span person.

Existing pipe joint component commonly used as shown in Figure 1, system is the body of right angle turnover shape without exception, big caliber of one end (2) tool and external diameter, pipe end also is provided with threeway or the bipass spare (figure do not show) of one section outside thread (3) for the input component that is spirally connected, end (4) then is less caliber and external diameter in addition, rearward end is established one section outside thread (5), preceding pipe end is then established the impaction part (6) that dwindles caliber, appropriate location and ring are established raised line (7), the body (8) of the output member of the corresponding caliber of system's confession forces and is inserted in, owing to making this body (8), raised line (7) is forced to enlarge in herein, make both connections tighter, but mat is tightened element (9) and is buckled such as the C type again, iron wire is tied up around, even need put leak-proof gasket sometimes, in case leak or leak gas, very impracticable, as shown in Figure 2, but because the drop of the internal diameter of joint (1) own, flow is by changeing little greatly rapidly, and the change in fluid pressure that makes stream pass through is big, and the body of output member (8) also the additional element (9) of tightening of a mat come tighten, the body (8) that is easy to generate of a specified duration gets loose even the explosion breakage, cause fluid to leak, therefore need often carry out safety inspection and maintenance, very inconvenient.

The main purpose of the utility model, tying up to provides a kind of new tube joint element that is suitable for various pipelines, and it makes connecting moves easily simple and firm, and the life-span person who prolongs pipeline.

The utility model system provides a kind of new tube joint element that is suitable for various pipelines, it is by the body that generally is right angle turnover shape, within tool is suitable, outer tube diameter, two pipe ends also all are provided with one section outside thread, one end system is for the tube connector of the input component that is spirally connected, end then cooperates and the urgent pipeline that is connected output member with a joint in addition, this joints sleeve outward appearance system is Hexagon like the nut shape, for being beneficial to gripping, its center is arranged with an inner bolt hole, threads engaged outside system and the body, and concentric be convexly equipped with a conical pipe, this taper pipe suitable length size, and do not exceed joints sleeve itself, the thicker upwards reduction gradually in its body bottom, but its center hole then is perforation with the diameter person, is to correspond to caliber within the body, makes the pipeline of output member must stretch in the center hole of conical pipe, when joints sleeve and body screw togather, because the effect of conical pipe and direct packing engages and is its characteristic person to pipeline.

Now lift a preferred embodiment and cooperate the graphic back that is illustrated in:

Fig. 3 is the three-dimensional exploded view of the utility model one preferred embodiment.

Fig. 4 is the enforcement schematic sectional view of the utility model one preferred embodiment.

See also shown in Figure 3, a kind of new tube joint element (10) that is suitable for various pipelines of the utility model, it is by the body (11) that generally is right angle turnover shape, within tool is suitable, outer tube diameter, caliber and connect identical in it, be different from the person of commonly using, can avoid build-up of pressure drop in body (11), two pipe ends (111) (112) also all are provided with one section outside thread, wherein an end (111) is the tube connector for the input component that is spirally connected, generally lead to such as two or three-way pipe (figure does not show), then packing is connected the pipeline (13) (seeing shown in Figure 4) of output member to end with a joints sleeve (12) cooperation in addition; This joints sleeve (12) is to be Hexagon such as nut shape, be beneficial to holding operation, the center is arranged with big inner bolt hole (121), system must be screwed corresponding to screw thread outside body (11) one ends (112), and concentric be convexly equipped with a conical pipe (122), this conical pipe (122) tool suitable length size, and do not exceed joints sleeve (12) itself.This conical pipe (122) tool center hole (123) is perforation with the diameter person, front end is established a supported terminal part (124) tool than minor diameter, and the thicker upwards reduction gradually in its body bottom, and the crack ecto-entad diminishes gradually and is its characteristic person between causing between conical pipe (122) and inner bolt hole (121).When pipeline (13) inserts joints sleeve (12), make pipeline (13) front end cooperate the insertion part of establishing reduced outside diameter, both offset and closely contact during insertion, strengthen connecting effect.

When making up according to above-mentioned construction device, see also shown in Figure 4, when being used in the gas of fluid machine or gas port that fluid piping is used, directly the be spirally connected tube connector of input component of body (11) one ends (111) of the utility model, end (112) is when connecting the pipeline of output member in addition, pipeline (13) front end is provided with the insertion part (131) of reduced outside diameter and directly makes pipeline (13) be inserted in its center hole of conical pipe (122) (123) of joints sleeve (12) by joints sleeve (12) bottom, and stretch out insertion part (131) that conical pipe (122) makes pipeline (13) and the supported terminal part (124) of conical pipe (122) and offset and be tight and contact, make the joints sleeve (12) and the end (112) of body (11) directly screw togather again, and in the action that screws togather, because the crack diminishes gradually between conical pipe (122) and the inner bolt hole (121), but body (11) is so constant being screwed into more of the thickness of itself promptly forces body (11) that the power of compressive strain is produced the compression packing to conical pipe (122), and be in contact with it tight pipeline (13) and produce the effect that compressing is tightened stretching into conical pipe (122), so screw togather finish after, promptly connected body (11) and pipeline simultaneously and (13); The various pipe joint elements (10) that are suitable for of the utility model cooperate with joints sleeve (12) with special body (11), and following advantage is provided.

(a) footpath is constant within the body (11), and fluid does not have pressure difference in interior circulation, and it is smooth and easy to circulate.Can cooperate the needs of different size to make various different size specifications and be applicable to various pipelines;

(b) directly with the design that inner bolt hole (121), conical pipe (122) and its center hole (123) supported terminal part (124) are arranged of joints sleeve (12), make pipeline (13) closely be connected and oppressed distortion and tighten connection with joints sleeve (12), need not be extra tighten element, leak-proof gasket etc., and assemble easily simple;

(c) the utility model pipe joint element (10) of connection output member and input component, the same caliber of two pipe ends, the joints sleeve (12) that connects the less pipeline of input component is also little with the caliber drop of body (11), suitable and pipeline (13) is to stretch into to be contained in joint component (10) inside with the pressure of output in input, can be just like commonly using the breakage of to split, situation that fluid leaks takes place, the phenomenon of the gas leakage that more can prevent to leak in the machine run;

(d) only need to be made up of body and joints sleeve, part is simple, cost is low, and has prolonged the life-span of pipeline.

In sum, the utility model, it cooperates the structure of innovation with special spatial shape, provide the assembling connecting moves easily simple and firm, pipeline can not split damaged its life-span of prolongation, has progressive effect and practicability and novelty, meets the regulation of utility model patent.
