Abstract
A pressure gauge damper comprises a damper body, one end of which is connected with a pressure gauge; and the pressure gauge damper is characterized in that the other end of the damper body is provided with an inner threaded hole which is internally provided with a cylindrical pin, and the cylindrical pin and the inner threaded hole are in interference fit to form a spiral runner. As for the pressure gauge damper, one end of the damper body is provided with the threaded hole which is internally provided with the cylindrical pin, the spiral runner is formed between the cylindrical pin and the threaded hole, the pressure pulse of a detected medium is greatly weakened after passing through a solenoid damper, and stable pressure is transmitted to the pressure gauge, therefore, the pressure gauge is effectively protected; and the pressure gauge damper has good damping effect, is simple in machining, and has a simple structure.
Description
Technical field
The utility model relates to the pressure piping measurement mechanism, relates in particular to a kind of tensimeter damper.
Background technology
Existing tensimeter damping unit comprises pressure pulse decompression body 1 and fittings body 2, one end of described pressure pulse decompression body 1 is connected with tensimeter, the other end is connected with described fittings body 2, described pressure pulse decompression body 1 and fittings body 2 are provided with elongated hole 3, filter the pressure surge on the pipeline of surveying by this elongated hole 3, reduce pressure pulse manometric impact.Elongated hole 3 processing difficulties on the pressure pulse of this tensimeter damping unit decompression body 1 and the fittings body 2 add and are easy to the drill bit that fractures man-hour, processing cost height not only, and also because the length and the aperture of this elongated hole are limited, its damping is not obvious.
The utility model content
The purpose of this utility model is to provide a kind of and is easy to process and tensimeter damper that damping is good.
The purpose of this utility model is to realize like this, a kind of tensimeter damper, comprise the damping body, one end of described damping body is connected with tensimeter, it is characterized in that: the other end of described damping body is provided with internal thread hole, in the described internal thread hole straight pin is housed, described straight pin and described internal thread hole interference fit form helical flow path.This helical flow path is a solenoid damper, and the pressure pulse of measured medium is greatly weakened after by this solenoid damper.
The utlity model has following beneficial effect; the utility model is provided with internal thread hole at an end of damping body; and in described internal thread hole, straight pin is installed, and forming the solenoid damper between described straight pin and the internal thread hole, the pressure pulse of measured medium is greatly weakened after by this solenoid damper; pass to tensimeter pressure stably; effectively protected tensimeter, not only damping is good, and handling ease; simple in structure, cost is low.
