Abstract
The utility model discloses a pressure gauge isolator, which comprises an upper cover, a lower cover and a membrane sharing the same axis, wherein the upper part of the lower cover is sleeved at the lower part of the upper cover through radial screw thread, the membrane is welded on the lower end surface of the upper cover, an upper step is arranged above the radial screw thread through the upper cover, a lower step corresponding to the upper step is arranged above the screw thread through the lower cover, a sawtooth gap is formed on the lower plane surface of the upper step and the plane surface of the lower step corresponding to the upper step respectively, and an annular sealing gasket is arranged between the lower plane surface of the upper step and the plane surface of the lower step. The thread-adding sealed double sealing structure of the sealing gasket has excellent sealing property and is convenient to change, can protect the isolator from being completely destroyed, and greatly reduce the use cost of the pressure gauge isolator.
Description
Technical field
The utility model relates to a kind of tensimeter field, concretely, is a kind of tensimeter isolator.
Background technology
As shown in Figure 3, the tensimeter isolator that links to each other with tensimeter 5 is made up of the last capping 1 of concentric, following capping 2 and diaphragm 3, and following capping 2 tops are by radially thread bush is in last capping 1 bottom, and diaphragm 3 is welded on the lower surface of capping 1.To after screwing with following capping 2, last capping 1 adopt the argon arc welding welding more earlier.Have the slit because of being threaded, must have medium to arrive the commissure by thread gaps, constantly butt welded seam is exerted pressure.Because of pressure medium is bigger, the time one is long, and the weld generation leakage phenomenon of last capping 1 and following capping 2 replaces with capping or following capping all compares difficulty, thereby causes the whole isolated device to be scrapped.
The utility model content
The utility model improves at the problems referred to above, and a kind of capping or following capping tensimeter isolator eaily all of replacing with is provided, and can not cause the whole isolated device to be scrapped.
For solving the problems of the technologies described above, the tensimeter isolator that the utility model adopts, the last capping that comprises concentric, following capping and diaphragm, described down capping top by thread bush radially at described loam cake basifacial, described diaphragm is welded on the lower surface of described upward capping, the described capping of going up is provided with above screw thread radially and tops bar, described capping down radially is being provided with and described corresponding the getting out of a predicament or an embarrassing situation of topping bar above the screw thread, on the described lower plane of topping bar and the corresponding with it plane of getting out of a predicament or an embarrassing situation, indentation is arranged, be provided with Gask-O-Seal between the plane at this lower plane of topping bar and corresponding getting out of a predicament or an embarrassing situation.
Adopt traditional screw thread will go up capping and couple together, last capping and following capping are sealed, on the upper and lower capping of sealing gasket, indentation is set simultaneously and carries out linear sealing with sealing gasket with following capping.This sealing gasket adds the double sealing structure of linear sealing, and the medium that can keep out the intermediate pressure of coming preferably from thread gaps impacts.Even occur leakage phenomenon in the use, it is all quite convenient to replace with capping or bottom end cover, can not cause the whole isolated device to be scrapped, and has greatly reduced the use cost of tensimeter isolated body.
The indentation that is provided with on last capping and following capping at least respectively is one.Two indentations have formed four potted lines, add the sealing of Gask-O-Seal, just can play the better seal effect.
Description of drawings
Fig. 1 tensimeter isolator of the present utility model.
Capping and following capping are respectively with the tensimeter isolator of two indentations on Fig. 2.
Tensimeter isolator before Fig. 3 improves.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Tensimeter isolator as shown in Figure 1 is made up of the last capping 1 of concentric, following capping 2 and diaphragm 3.Last capping 1 bottom is provided with radially external thread, and following capping 2 tops are provided with corresponding internal thread, following capping 2 tops by thread bush radially in last capping 1 bottom.Diaphragm 3 is welded on the lower surface of capping 1.Capping 1 tensimeter 5 links to each other on the tensimeter isolator.Last capping 1 radially is being provided with the 1a that tops bar above the screw thread, following capping 2 radially is being provided with the get out of a predicament or an embarrassing situation 2a corresponding with the 1a that tops bar above the screw thread, on the lower plane of the 1a that tops bar and the corresponding with it 2a plane of getting out of a predicament or an embarrassing situation, indentation is arranged, be provided with Gask-O-Seal 4 between the 2a plane in lower plane and corresponding the getting out of a predicament or an embarrassing situation of the 1a that tops bar.
The indentation that is provided with on last capping 1 and bottom end cover 2 at least respectively is one, each indentation forms two potted lines, upper and lower two indentations form four potted lines, add the sealing of Gask-O-Seal, can satisfy the seal request of intermediate pressure isolator.As shown in Figure 2, also can respectively be provided with two according to the structure of last capping 1 and following capping 2, or more indentation.Used sealing gasket can be phenyl tetrafluoride pad or other sealing gaskets that is suitable for using in the tensimeter.
Claims (2)
1. tensimeter isolator, the last capping (1) that comprises concentric, following capping (2) and diaphragm (3), described down capping (2) portion is by capping (1) bottom on described of thread bush radially, described diaphragm (3) is welded on the lower surface of described upward capping (1), it is characterized in that: the described capping (1) of going up radially is being provided with top bar (1a) above the screw thread, described capping (2) down radially is being provided with and corresponding the getting out of a predicament or an embarrassing situation of described topping bar (1a) (2a) above the screw thread, on the lower plane of described topping bar (1a) and corresponding with it (2a) plane of getting out of a predicament or an embarrassing situation, indentation is arranged, be provided with Gask-O-Seal (4) between (2a) plane this top bar (1a) lower plane and getting out of a predicament or an embarrassing situation of correspondence.
2. according to the described tensimeter isolator of claim 1, it is characterized in that: the described indentation of going up on capping (1) and the following capping (2) at least respectively is one.
