Abstract
The utility model relates to a damper of a pressure meter, which is used for measuring the pressure of media. The utility model is composed of an upper casing 1, a lower casing 2, and a taper screw 3. The utility model is characterized in that the bottom position of the notch 5 of the upper casing 1 and the upper end of a through hole 4 are tapered; the inner side of the utility model is provided with screw threads which can be matched with the taper screw 3. The middle of the upper casing 1 is additionally provided with a damper chamber and a diaphragm type bellow. The utility model has the advantage of simple structure, and the utility model has the function of preventing corrosion because the diaphragm type bellow 7 is adopted.
Description
The utility model relates to a kind of pressure ga(u)ge damper of measuring media pressure.
When with tensimeter medium being measured, the surge pressure during owing to startup is bigger, can damage tensimeter, has reduced manometric serviceable life.Utility model patent CN2132173Y provides a kind of protector (see figure 1), the surge pressure when starting to alleviate.It is made of the piston of a time-delay cushion chamber and an on-off action, the valve piston cover that in cushion chamber, is provided with the piston that has throttle orifice on it and has throttling channel, along with the mobile throttle orifice and the throttling channel of piston opens or closes automatically in turn, also be provided with the retaining valve of release effect on the piston, put at valve piston and to be provided with spring, piston is slowly moved right, also be provided with O-ring seal in this exocoel.The shortcoming of this utility model is a complex structure, and does not have anti-corrosion function.
The purpose of this utility model provides a kind of shatter-proof pressure ga(u)ge damper simple in structure.
Another purpose of the present utility model provide a kind of can be shatter-proof again can the corrosion-resistant diaphragm pressure gage impact damper.
Embodiment of the present utility model is: it is made of upper shell 1, lower house 2, cone screw 3.Fixedly connected with the upper end of lower house 2 in the lower end of upper shell 1, and there is a through hole 4 to link to each other end to end, there is a recess 5 to link to each other in the upper end of upper shell 1 with through hole 4, in this recess, be provided with the internal thread that can match with tensimeter, be provided with the external thread that can match with working equipment at the afterbody of lower house 2, it is characterized in that: the bottom position of the recess 5 of upper shell 1, the upper end of through hole 4 are taper, and its inboard is provided with the screw thread that can match with cone screw 3.
Another embodiment that this practicality is newly moulded is: a cushion chamber 6 and a diaphragm type corrugated tube 7 are set in the centre of above-mentioned upper shell 1 again.
The utility model has the advantages that simple in structure, and owing to adopted the diaphragm type corrugated tube, so have corrosion proof function.
Now be described as follows in conjunction with the accompanying drawings and embodiments:
Fig. 1 is one of a utility model embodiment cut-away view;
Fig. 2 is two cut-away views of the utility model embodiment.
Upper shell 1 of the present utility model is connected with working equipment by the screw thread of its afterbody with tensimeter engagement, lower house 2 by the internal thread of recess 5, also can be threaded.
Fig. 1 is one of the utility model embodiment, the bottom position of the recess 5 of upper shell 1, and the upper end of through hole 4 is taper, its inboard is provided with the screw thread that can match with cone screw 3.Actuating medium passes to tensimeter by through hole 4 with pressure, pore size between its screw thread of cone screw 3 scalable, thereby when regulating pressure jump to manometric impulsive force, can greatly prolong manometric mission life like this.
Fig. 2 is two of embodiment of the present utility model, it is on the basis of the foregoing description, a cushion chamber 6 and a diaphragm type corrugated tube 7 are set in the centre of shell body 1, the medium of tested equipment acts on diaphragm type corrugated tube 7, make it to produce distortion, working fluid is formed pressure, conduction by working fluid, gap through cone screw 3 flows to tensimeter, corrugated tube of the present utility model has buffer action, it is isolated the tested media and the manometric actuating medium of equipment, and the equipment medium of avoiding is turbid to manometric corruption.
