Abstract
The utility model discloses a multi-stage throttling orifice plate group. The multi-stage throttling orifice plate group comprises a joint body, a connecting pipe, a sleeve, a plurality of throttling orifice plates and a sealing gasket, wherein the joint body is in threaded connection with or welded with the connecting pipe through the sleeve, the sealing gasket and an outer sleeve nut; the throttling orifice plates are arranged between the joint body and the connecting pipe through the sleeve at intervals; the joint body, the connecting pipe, the sleeve and the throttling orifice plates are made of metal materials; and the sealing gasket is made of non-metal or metal materials. The utility model has the benefits that the multi-stage throttling orifice plate group is sleeved or welded with pipelines, so that the mounting space is greatly reduced, the materials are saved, convenience is brought for use, and a good throttling pressure-reducing effect is achieved due to multi-stage throttling.
Description
Technical field
The utility model relates to a kind of restriction orifice, particularly a kind of multistage restriction orifice.
Background technique
The restriction orifice of at present domestic production is mostly taked the single-stage restriction orifice, the structure that two ends connect with flange, and consume material not only, and take installing space, current limitation effect is not ideal enough.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of multistage restriction orifice group, has improved the step-down current limitation effect, with specific (special) requirements and the saving material that satisfies craft piping.
To achieve these goals, the utility model solves the technological scheme that its technical problem adopts and is:
Multistage restriction orifice group comprises fittings body, adapter, sleeve, several restriction orifices, gasket seal, and fittings body is threaded by sleeve, gasket seal and cap nut employing with adapter or is welded to connect.
Described restriction orifice is disposed between fittings body and the adapter by sleeve.
The material of described fittings body, adapter, sleeve, restriction orifice is metallic material, the nonmetal or metallic material of gasket seal.
The beneficial effects of the utility model: the restriction orifice of the multistage restriction orifice group that the utility model provides and pipeline socket or welding, these Placements greatly reduce installing space and save material, and offer convenience to use, multistage current limliting particularly, the current limliting antihypertensive effect is good.
