Abstract
The utility model relates to a soft fitted joint for a pressure gauge, which belongs to the technical field of industrial automatic instruments. The public known technical pressure gauge can be only fixedly installed, which is inconvenient for installation and reading. The utility model is characterized in that a section of flexible conduit or a steel armored pipe which is provided with a capillary serpentine pipe or a high pressure rubber pipe is installed under the pressure gauge. In such a way, the gauge head of the pressure gauge can be higher or lower, facing upward or downward, and can rotate horizontally or vertically; the position and the angle of the sighting surface can be regulated according to the demand of operator; the observation is convenient, and the reading is accurate; the pressure gauge can be renewed without changing the original producing line.
Description
The utility model belongs to industrial automation instrument link technical field.
Pressure is one of important parameter of industrial detection, and tensimeter then is tonometric main instrument.Tensimeter all is to be fixedly mounted on the specific technology position such as machinery and equipment, pipeline, tower pump by nut in prior art.Although can take into account convenient the observation and fit sealing by suitable adjustment when mounted, but, after fixed installation, just can not do any change again, cause some site operation personnel, have to climb up certain height or turn over certain angle in order to observe pressure, go to look up or overlook, so not only make troubles, and make reading produce error easily, influence manometric correct use to the observer.
In order to solve this technical barrier, a connecting hose can be installed between tensimeter and field engineering position, installing one promptly for the pressure gauge outfit can face upward and can bow again, can protract, can after contract and rotatable neck, become original fixed tensimeter and be movable tensimeter, or be band neck formula tensimeter, make the angle of tensimeter sightingpiston with highly all can be along with the different and any adjustment of site operation personnel's requirement.The designed connecting hose of the utility model system adorns one section a little longer capillary spiral pipe by general flexible metal conduit in it and forms.The flexible metal conduit upper end is connected with the pressure gauge outfit of known technology by nut, and its lower end is connected with manometric coupling by nut, and manometric former joint welding is inserted in the upper end of the capillary spiral pipe in the flexible metal conduit, and manometric coupling welding is inserted in its lower end.
Major advantage of the present utility model is that the tensimeter of such connecting hose has been installed, rely on the winding degree of flexible metal conduit and capillary spiral pipe, guaranteeing under the fastening prerequisite of tensimeter installation sealing, can make gauge outfit along with site operation personnel's use intention is done rotation level or vertical, can face upward, can bow, the height of tensimeter sightingpiston is changed within the specific limits by armoured flexural deformation, like this, it is convenient not only to observe, and accuracy of reading.In addition, increased the capillary spiral pipe owing to measure in the pipeline, thereby increased damping action, made the gauge hand indication of under the vibration occasion, using steady.The manometric production line of original production is not done any change, and only such connecting hose on increasing under the gauge outfit of producing can make former tensimeter update, thereby improve this class instrument competitive power in the international market.
Accompanying drawing is the synoptic diagram that facing of one of the utility model most preferred embodiment and one side are cut open.(1), (2) are known tensimeter among the figure, and (3) and (4) are the attaching nut, and (5) are flexible metal conduit, and (6) are the capillary spiral pipe, and (7) and (8) are that attaching nut (9), (10) are pad, and (11) are the tensimeter coupling.
In this embodiment, it is 5～8cm that the snakeskin piping adopts φ 20mm plated metal flexible metal conduit length, and the capillary spiral pipe then adopts φ 2.5～3.5mm carbon steel pipe or stainless-steel tube, and length is 7～10cm behind its spiral.
As a kind of conversion of present embodiment, flexible metal conduit can be used the wire armoring pipe instead, and the capillary spiral pipe also can change high-pressure rubber hose into.
When being used for needing special corrosion-resistant occasion as tensimeter, but the lining teflon flexible pipe can adopt the cutting ferrule ring to be connected with the pressure-resistant seal of joint in the high-pressure rubber hose.
Claims (3)
