Description

A kind of band buffer mechanism pressure gauge

Technical field

The utility model is related to instrument field, and in particular to a kind of band buffer mechanism pressure gauge.

Background technology

Pressure is the size that pressure is born in pressure physically, i.e. unit area.On the basis of atmospheric pressure, use The instrument of atmospheric pressure is less than or greater than in measurement, and the instrument for measuring fluid (gas, liquid) pressure is all pressure Table.

At present, in use, pressure gauge itself does not carry pooling feature, in tested media, instantaneous pressure to pressure gauge It is excessive or too small, indicator fast reaction or moment back to zero are caused, banking pin is clashed into, indicator bending, deformation are made, when serious even More than banking pin.Therefore, pressure gauge meeting build-up of pressure table service life crosses section or tested media read untrue, gives production band To cut with scissors burden.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems in the prior art, there is provided a kind of buffer mechanism control of band Pressing pressure table, itself carries separator tube, is easy to protect gauge hand, contained spring pipe and transmission mechanism, simple structure, side Just it is practical.

To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the utility model is to be achieved through the following technical solutions：

A kind of band buffer mechanism pressure gauge, including dial plate, separator tube, interface unit, housing, range, bourdon tube, driver Structure, pointer, are provided with housing protection dial plate outside the dial plate, the interface unit connects separator tube, the connection of the separator tube other end Elastic sensing element bourdon tube, bourdon tube other end connection transmission mechanism, transmission mechanism concatenation pointer.

Preferably, the housing is strengthens glass material, prevents from using or breaks when idle, is increased the service life.

Preferably, the interface unit can select the interface unit of unlike material to be connected according to tested media difference Connect.

The beneficial effects of the utility model are：

1st, whole pressure meter structure is simple, convenient and practical, and pressure watch shell is strengthens glass, is effectively protected internal dial plate Deng anti-corrosion, shatter-resistant increase the service life.

2nd, pressure gauge is convenient without the need for installing buffer unit during pressure gauge use per se with separator tube Practicality, in tested media press process, by interface unit pressure gauge is directly connected to, and its internal damping pipe refers to pressure gauge Pin, contained spring pipe and transmission mechanism are effectively protected, simple structure, convenient and practical, and extend pressure gauge service life.

Certainly, implement arbitrary product of the present utility model to it is not absolutely required to while reaching all the above advantage.

Description of the drawings

In order to be illustrated more clearly that the technical scheme of the utility model embodiment, below will be to making required for embodiment description Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present utility model, For those of ordinary skill in the art, on the premise of not paying creative work, can be with according to these accompanying drawings acquisitions Other accompanying drawings.

Fig. 1 is the manometric structural representation of band buffer mechanism described in the utility model；

In accompanying drawing, the list of parts representated by each label is as follows：

1- housings, 2- separator tubes, 3- dial plates, 4- interface units, 5- ranges, 6- bourdon tubes, 7- pointers, 8- transmission mechanisms.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The all other embodiment for being obtained, belongs to the scope of the utility model protection.

Refer to shown in Fig. 1, the utility model is a kind of band buffer mechanism pressure gauge, including dial plate (3), separator tube (2), It is provided with outside interface unit (4), housing (1), range (5), bourdon tube (6), transmission mechanism (8), pointer (7), the dial plate (3) Housing (1) protects dial plate, the interface unit (4) connection separator tube (2), separator tube (2) other end connection elastic sensing element Bourdon tube (6), bourdon tube (6) other end connection transmission mechanism (8), transmission mechanism (8) concatenation pointer (7).

Wherein, housing (1) is strengthens glass material, prevents from using or breaks when idle, is increased the service life.

Wherein, interface unit (4) can select the interface unit (4) of unlike material to be connected according to tested media difference Connect.

One of the present embodiment has particular application as：During using pressure gauge tested media pressure, by interface unit (4) pipeline Connection separator tube (1), tested media buffering in separator tube (1) reduces pressure, and producing elastic deformation by bourdon tube (6) will not Moment is excessive, and the elastic deformation that bourdon tube (6) is produced acts on connected transmission mechanism (8) and also do not allow to be also easy to produce instantaneous variation, Drive pointer (7) to be difficult instant movement change, after tested media pressure terminates, remove the tested media of interface unit (4) connection, Because the reason for separator tube (1), gauge hand (7) will not moment back to zero cause to damage, it is its simple structure, convenient and practical, can Protect pressure gauge tested media instantaneous pressure excessive or too small and cause to damage.
