Abstract
The invention discloses a spring tubular pressure gauge, comprising a body (9), a reading mirror (4), an indicator (5), and a dial plate (6). The body is provided with a spring tube (7) inside, and the bottom of the body is provided with a center hole (10), which is connected with the spring tube. The spring tubular pressure gauge is characterized in that an indicator frame (1) is positioned inside the body. The terminal of the indicator is connected with a crank (2), and the indicator can be pivotally positioned on the indicator frame. A groove (12) is positioned on the spring tube, and the crank is arranged inside the groove. The spring tubular pressure gauge has the advantages that the length of the indicator meets the national standard, and the indicator is convenient to observe and adjust and finally improves the precision of the pressure vessels.
Description
[technical field]
What the present invention relates to is a kind of tensimeter, is used for the pressure indication of various containers, is specially adapted to the pressure indication of flame snuffer.
[background technology]
At present, the pressure-indication means that is used for pressure vessel is more, and structure is also varied.The most frequently used flame snuffer tensimeter, its structure all includes table body, table mirror, in the table body, be provided with multi-turn bourdon tube, pointer and dial plate, bottom at the table body has the center pit that gas imports, and is provided with filtrator in the described center pit, and described multi-turn bourdon tube is arranged on the center in the table body, and the multi-turn bourdon tube has a free end, the end of its pointer directly links to each other with the free end of multi-turn bourdon tube, expands when the multi-turn bourdon tube is subjected to air pressure and when rotating, drives pointer and rotate with indicated pressure.The tensimeter of this structure, because the end of pointer directly links to each other with the free end of multi-turn bourdon tube, cause the length of its pointer to be restricted, thereby finally make the tensimeter pointing accuracy of this structure not high, observe to adjust inadequately and make things convenient for, particularly tensimeter has national standard, requires the pointer length should be less than 9 millimeters, and the tensimeter of this structure has not reached national standard.
[summary of the invention]
In view of the deficiency that background technology exists, the technical problem to be solved in the present invention provides a kind of being convenient to and observes adjustment, can make pointer length elongated, and a kind of bourdon gauges that can be up to state standards.
For this reason, the present invention takes following technical scheme to realize: a kind of bourdon gauges, include table body, table mirror, pointer and dial plate, be provided with bourdon tube in described table body, have the center pit that gas imports in the bottom of table body, this center pit is communicated with described bourdon tube, it is characterized in that in the table body, pointer being installed, the end of described pointer be installed in rotation on the pointer after a crank is connected, on described bourdon tube, be connected with allocating slot, described crank places described allocating slot; Described dial plate is installed in the top of pointer, and described pointer is then above described dial plate; Inboard at the table body is provided with projection, and described pointer is placed on the described projection; Described pointer is arc, its arc circular arc and table body circumferential inner wall coupling, and the end of its pointer is installed in the mid point of bowstring.
Among the present invention, adopt a pointer that pointer is installed, and adopt allocating slot to be connected with crank " moving ", make that observation and adjustment pointer are comparatively convenient, and the length of the pointer that extended meets it and is not less than 9 millimeters national standard, in its table body projection is set, pointer just can be placed on this projection easily, and it is extremely convenient to install; The pointer that it is arc and the end of pointer are installed in the mid point of bowstring, more can prolong the length of pointer, improve its pointing accuracy.
[description of drawings]
Further describe relevant details of the present invention below more in conjunction with the accompanying drawings.
Fig. 1 is a structural drawing of the present invention;
Fig. 2 is the vertical view of Fig. 1 of the present invention;
Fig. 3 is the structural drawing of pointer of the present invention.
[embodiment]
With reference to accompanying drawing, this bourdon gauges, include table body 9, table mirror 4, pointer 5 and dial plate 6, in described table body 9, be provided with multi-turn bourdon tube 7, bottom at table body 9 has the center pit 10 that gas imports, this center pit 10 is communicated with described bourdon tube 7, in described center pit 10, be provided with filtrator 11, be provided with projection 8 at table body 9 inwalls, be placed with pointer 1 on this projection 8, its pointer 1 is arc, arc circular arc and table body 9 circumferential inner walls coupling, one rotating shaft 3 is installed on the mid point of the bowstring of pointer 1, the end and the crank 2 that connect described pointer 5 at the two ends of rotating shaft 3 respectively are so the rotation of crank 2 just can drive the rotation of pointer 5, mid point with rotating shaft 3 installation pointers 1 bowstring makes that its pointer length of tensimeter of this structure is the longest; Be welded with allocating slot 12 on described bourdon tube 7, the end of described crank 2 places described allocating slot 12; Described dial plate 6 is installed in the top of pointer 1, and then above described dial plate 6, the scale on 5 indication dial plates 6 of pointer is to show the pressure size for described pointer 5.When being installed in the present invention on the pressure vessel, the size of its container pressure, all import this manometric center pit 10 by gas in the container, gas flows into multi-turn bourdon tube 7 through center pit 10, multi-turn bourdon tube 7 is subjected to the gaseous tension after expansion and rotates, and the allocating slot 12 that then drives on the bourdon tube 7 rotates, and drives crank 2 simultaneously and rotates, thereby make pointer 5 rotate the pressure in the indicated pressure container.This bourdon gauges is simple in structure, and indication is accurate, and is convenient to observe and adjust, and meets the standard of country about pressure indicator.
Claims (4)
