Abstract

The invention discloses a pressure gauge with a protection device, and relates to the technical field of instruments and meters, in particular to the pressure gauge. The pressure gauge comprises a pressure gauge body and a protection cover, wherein the shape of the protection cover is matched with that of a dial protection panel on the pressure gauge body. The protection cover wraps the dial protection panel. Furthermore, a perspective window for observing scales on the pressure gauge is formed in the protection cover. In addition, a protection film is further arranged on the protection cover. Preferentially, the pressure gauge body and the protection cover are respectively provided with a plurality of corresponding connecting holes, bolts are arranged in the connecting holes, and the pressure gauge body is fixedly connected with the protection cover through the bolts. Preferentially, the outer side wall of the pressure gauge body and the inner side wall of the protection cover are provided with matched threads, and the protection cover is connected to the pressure gauge body in a threaded mode. The pressure gauge can be widely used in the fields of automobiles, engineering machines, coal mining equipment, chemical equipment and the like, and can be used for monitoring or controlling pressure of gas in a pipeline.

Description

Tensimeter with protective device
Technical field
The present invention relates to technology of instrument and meter field, especially a kind of tensimeter.
Background technology
Tensimeter is mainly used in monitoring the working pressure of the inner institute filling mediums such as pressure-vessel, pipeline and pipeline; to control rightly pressurized capacity; the safety of protection equipment; or by grasping pressure parameter; for monitoring, control and regulate to produce, operating personnel provide reliable foundation; therefore, tensimeter can be widely used in the fields such as automobile, engineering machinery, coal mine equipment, chemical plant, is a kind of very important instrument and meter.
But existing tensimeter index dial protection panel firmness is not high; when being subject to the external force such as sandstone shock, vibration, easily break; and in use easily there is cut in index dial protection panel; affect the sharpness of index dial protection panel; in addition; if sealing property is bad between index dial protection panel and tensimeter, easily enter steam and dust and other impurities, affect the precision of instrument.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tensimeter with protective device, and this tensimeter has good impact resistance and vibration performance, better wearing quality and sealing, and also its protective device is easily changed.
In order to solve the problems of the technologies described above, the present invention includes tensimeter body, and with tensimeter body on the protective cover of index dial protection panel form fit, described protective cover is wrapped on index dial protection panel.
Further, on described protective cover, be provided with for observing the see-through window of tensimeter scale.
Further, on described protective cover, be also provided with diaphragm.
Preferably, be respectively arranged with the connecting hole of some correspondences on described tensimeter body and protective cover, in described connecting hole, be provided with bolt, described tensimeter body and protective cover are bolted to connection.
Preferably, be provided with the screw thread of coupling on the lateral wall of described tensimeter body and the madial wall of protective cover, described protective cover is threaded on tensimeter body.
The present invention, by tensimeter index dial protection panel, a protective cover being set, has further improved manometric impact resistance and vibration performance, and waterproof and anti-dust performance, and on protective cover, is provided with diaphragm, has improved anti-wear performance.In addition, owing to being bolted between protective cover and tensimeter body, or protective cover is directly threaded on tensimeter body, when protective cover damages, without changing whole tensimeter, only needs to change protective cover, can save use cost like this.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
Embodiment
The embodiment that the present invention is cited; just for helping to understand the present invention; should not be construed as limiting the scope of the present invention; for those skilled in the art; without departing from the inventive concept of the premise; can also the present invention be improved and be modified, these improvement and modification also fall in the scope of the claims in the present invention protection.
As depicted in figs. 1 and 2, the present invention includes tensimeter body 1, be provided with the protective cover 2 of a form fit on the index dial protection panel 3 of tensimeter body 1, described protective cover 2 is wrapped on the index dial protection panel 3 of tensimeter body.If index dial protection panel 3 is boss-shaped, at this moment a size and the groove that index dial panel 3 mates can be set on protective cover, be convenient to protective cover 2 to withhold on index dial protection panel 3.
Protective cover 2 is generally made by transparent material, if protective cover 2 is made by non-transparent material such as metals, on protective cover 2, must arrange one for observing the see-through window of tensimeter scale, and this see-through window is made by transparent materials such as organic glass.
In protective cover use procedure, occur cut, affect the sharpness of tensimeter index dial, the diaphragm of layer of transparent can be set on protective cover surface, the diaphragm directly more renewing when diaphragm can not meet use just can.
As one embodiment of the present of invention, as depicted in figs. 1 and 2, on described tensimeter body 1 and protective cover, be respectively arranged with joint flange, on flange, be provided with 3 corresponding connecting holes, in connecting hole, be provided with bolt, described tensimeter body 1 and protective cover 2 are bolted to connection.
As the another kind of connected mode of tensimeter body and protective cover, on the madial wall of the lateral wall of described tensimeter body 1 and protective cover 2, can be provided with the screw thread of coupling simultaneously, protective cover 2 can directly be threaded on tensimeter body 1.
The present invention can be widely used in the fields such as automobile, engineering machinery, coal mine equipment, chemical plant, for monitoring or control the gaseous tension of pressure-vessel, pipeline and pipeline.The present invention has impact resistance and vibration, anti abrasive advantage, and also the protective cover on tensimeter is easy to change, and after protective cover damages, without changing whole tensimeter, only needs to change protective cover, reduced manometric replacement cost.
