Abstract
The utility model discloses a throttling element with a joint, which is composed of a casing and a throttling component. The casing is provided with a through hole in the axial direction. The radial outer ends of both ends in the axial direction form a welding joint shape. The shape of the part across which a fluid flows in the axial direction of the throttling component is the same as that of the part across which a fluid flows in the axial direction of a common throttling component. The throttling component has four forms of a pore plate, a reducing nozzle, a reducing and diverging nozzle and a diverging nozzle. The throttling component is fixed in the through hole in the axial direction of the casing, and is connected with the casing into a whole. Thus, the throttling element with a joint can be connected with a pipeline in a welding mode. In order to improve the abrasion resistance and the corrosion resistance of the throttling element with a joint and reduce manufacturing cost at the same time, different parts of the throttling element with a joint can be made of different materials. For example, the throttling component is made of abrasion resistant and corrosion resistant materials, and the casing is made of common materials.

When restricting element adopts flange to connect,, there is inadequate natural endowment that the flange connection place may leak working medium and shortcoming such as complexity is installed though be easy to change advantage such as restricting element.These drawbacks limit that flange connects the use of restricting element, perhaps make the application of restricting element produce bad spinoff.
Summary of the invention
When connecting, restricting element and pipeline adopt the existing drawback of flange connecting mode in order to overcome, the purpose of this utility model is to propose a kind of restricting element that has welding joint, this restricting element can connect with the mode of pipeline with welding, connects thereby realize not having leaking.
The technical solution that realizes above-mentioned purpose is: a kind of restricting element of belt lacing, form by throttling element and shell, it is characterized in that, described shell a through hole axially arranged, throttling element is fixed in the shell axially extending bore, and the radial outer end at the axial two ends of shell has the welding joint of groove shape.
The restricting element of belt lacing of the present utility model owing to designed welding joint, can connect pipeline with the mode of restricting element with welding, connect thereby realize not having leaking, and be easy to install.The utility model is particularly suitable for frequently not changing the place that restricting element, working medium can not leak.

Embodiment
A kind of restricting element of belt lacing is made up of shell and throttling element.Enclosure axis is to there being a through hole, and axially the radial outer end at two ends partly has the welding joint shape.The axial flow of throttling element is the same through the shape of fluid section through the axial flow of the shape of fluid section and existing restricting element, comprises four kinds of forms such as orifice plate, convergent jet pipe, convergent divergent nozzle, divergent nozzle.Throttling element is fixed in the shell axially extending bore and shell is connected into an integral body.The restricting element of belt lacing just can connect with welding manner with pipeline like this.
With throttling element the method in the shell axially extending bore of being fixed on welding process is arranged, to four kinds of basic skills such as top method, embedding inlay technique, integration methods, and these four kinds of basic skills method of decomposing, being combined to form.
1. welding process: referring to Fig. 3, throttling element is selected convergent jet pipe 8 for use, adopts the method for welding convergent jet pipe 8 to be welded in the through hole of shell 7, and the radial outer end at the axial two ends of shell 7 has welding joint 6.Constituting throttling element is the restricting element structure of the belt lacing of convergent jet pipe 8;
2. to the top method: referring to Fig. 4, throttling element is selected orifice plate 5, and orifice plate 5 is in the through hole of shell 7, and the radial outer end at the axial two ends of shell 7 has welding joint 6, and constituting throttling element is the restricting element structure of the belt lacing of orifice plate.The fixed form of orifice plate 5 in the through hole of shell 7 is: with the position of orifice plate 5 in shell 7 axially extending bores is object of reference, and shell 7 axially extending bore axial components are called first side, second side in the disalignment of orifice plate 5 to end face portion.Make the diameter of first side equal the external diameter of orifice plate 5, whole or the only close orifice plate section diameter of second side is less than the external diameter of orifice plate 5, and one maintenance ring 9 being set in the first side, this maintenance ring 9 and shell 7 are connected in one with welding manner or spiral shell mosquito connecting mode or other connecting mode.Be fixed ring 9 and second side of orifice plate 5 withstood like this, realizes the purpose that orifice plate 5 and shell 7 is fixing.
In Fig. 4, locating ring 9 connects with the mode and the shell 7 of welding.Certainly locating ring 9 can also adopt other connecting mode and shell 7 to link.In Fig. 4, shell 7 is consistent at the diameter of the through hole of locating ring 9 right side parts, and shell 7 can be inconsistent at the diameter of the through hole of locating ring 9 right side parts certainly.Shell 7 for example is provided with the endless belt (be commonly called as and be seam) of a projection in the through hole of locating ring 9 right side parts, orifice plate 5 can be fixed with this endless belt and locating ring.
3. embedding inlay technique: referring to Fig. 5, throttling element is selected convergent divergent nozzle 10, and convergent divergent nozzle 10 is in the through hole of shell 7, and the radial outer end at the axial two ends of shell 7 has welding joint 6, constitutes the restricting element structure of belt lacing.
The fixed form of convergent divergent nozzle 10 in the through hole of shell 7 is: convergent divergent nozzle 10 is embedded in the shell, and that a part of cross sectional shape that convergent divergent nozzle 10 embeds shell 7 is a rectangle.According to the needs of physical strength, processing technology, that a part of cross section that throttling element embeds shell 7 can also be other shape, as trapezoidal etc.
4. integration method: referring to Fig. 6, throttling element is selected divergent nozzle restricting element structure (being the part that square frame 11 surrounds among Fig. 6), and throttling element and shell are processed into an integral body, and the two is to be processed under the condition that does not have separation by same block of material.
The top method had the throttling element of replacing advantage easily.Welding process, top method, embedding inlay technique are had throttling element can use different materials with shell, the advantage of favourable reduction cost.The integration method has the advantage of being convenient to process.
Among above-mentioned Fig. 3～Fig. 6, the shape of the welding joint 6 of the restricting element of belt lacing (being welding joint pattern and groove size) can be according to the inside nominal diameter and the nominal pressure of pipeline, according to " GB/T 9124-2000 steel pipe flanges technical conditions " or substitute the determining of new standard of this national standard, can meet national standard with restricting element and the welding quality between the pipeline that guarantees belt lacing.
Can adopt monoblock cast to go out blank, and then produce the restricting element of the belt lacing that adopts embedding inlay technique or integration method through the manufacture method of machining.Certainly, also can use other manufacture method to produce the restricting element of the belt lacing that adopts embedding inlay technique or integration method.
Wearing quality, corrosion resistance for the restricting element that improves belt lacing, reduce manufacturing cost simultaneously, the variant part of the restricting element of belt lacing can adopt different materials, and for example throttling element adopts and has wear-resisting, corrosion-resistant material, and the shell common material.
