Abstract
The utility model relates to a pressure gauge with an adjustable alarming device. The pressure gauge comprises a gauge plate (1), an outer transparent cover (2), a reading pointer (3) and a connector (4), wherein the outer transparent cover (2) is arranged at the outer part of the gauge plate (1) in a sleeving manner; the reading pointer (3) is connected with a pressure measuring mechanism; and the connector (4) is connected with the pressure measuring mechanism. The pressure gauge with the adjustable alarming device further comprises a green lower limit pointer (5), a red upper limit pointer (6) and a shaft sleeve; a fixing supporting column is arranged at the bottom part of the sleeve shaft and is fixedly connected to a central position in the gauge plate (1); the lower limit pointer (5) and the upper limit pointer (6) are respectively fixed to the middle part of the shaft sleeve; the upper part of the shaft sleeve is fixed to the center of the outer transparent cover (2) through a cap; and a groove shaped adjusting knob (8) is arranged at the top part of the shaft sleeve. The pressure gauge with the adjustable alarming device has the advantages that the alarming range can be adjusted by the groove shaped adjusting knob, and the adjustment is simple and convenient; the green pointer represents low-pressure alarm, and the red pointer represents high-pressure alarm, thereby, good alarming effect is realized; and the original structure of the pressure measuring mechanism is not changed.
Description
Technical field
The utility model relates to a kind of instrument and meter for test pressure, particularly a kind of tensimeter with adjustable alarming device.
Background technology
Tensimeter is used for measuring and indicates instrument higher than environmental pressure.Manometric application is very general, and it almost spreads all over all industrial flows and scientific research field.Be seen everywhere in fields such as heat distribution pipe network, oil gas transmission, water and air supply system, vehicle maintenance maintenance factory shops, especially in industrial process control and commercial measurement process, because the elastic sensing element of mechanical compression table has very high physical strength and the characteristic such as convenient for production, make the mechanical compression table obtain using more and more widely.
In industrial circle, tensimeter for detection of the pressure of device interior, is the requisite instrument that prevents security incident, damage equipment.especially when gasser is exploited, the down-hole pressure fluctuation changes larger, the down-hole pressure in different gas production period also has obvious cyclical variation, for example: the initial stage of production sometimes wellhead pressure up to 100MPa, exploitation mid-term and late period pressure drop to 40～50 MPa, perhaps lower below 10 MPa, but, this situation is also also unstable, often also have repeatedly, for this situation, in order to guarantee the safety of gas production and transmission pipeline network, just must monitor at any time the variation of pressure, so that the operative employee in time takes corresponding measure to guarantee to adopt the normal operation of transfer device safety.In order to guarantee the safety of operating personnel and plant equipment, usually load onto tensimeter on the equipment with pressure.But complicated due to working environment, change soon, add most of well site and carry out rotation break tour system, next class personnel inevitably can occur sometimes ignore the situation that pressure changes, thereby cause serious security incident.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of tensimeter with adjustable alarming device of regulating caution scope, good warning effect and not changing pressure survey mechanism original structure is provided.
the purpose of this utility model is achieved through the following technical solutions: a kind of tensimeter with adjustable alarming device, it comprises dial plate, be sleeved on the transparent housing of dial plate outside, the reading pointer that is connected with pressure survey mechanism and the joint that is connected with pressure survey mechanism, it also comprises the lower limit pointer, upper limit pointer and axle sleeve, the axle sleeve bottom is provided with anchor post, the center of anchor post and dial plate is fixedly linked, the middle part of axle sleeve is fixed with respectively lower limit pointer and upper limit pointer, the top of axle sleeve is fixed on the center of transparent housing by nut, the top of axle sleeve is provided with adjusting knob.
Described lower limit pointer is surperficial greeny pointer.
The pointer that described upper limit pointer takes on a red color for the surface.
Described adjusting knob is the flute profile knob.
The utlity model has following advantage:
1, be provided with the flute profile knob at the top of axle sleeve, can regulate manometric caution scope by tablet (bottle opener, blade etc.), easy to adjust, simple.
2, the low pressure limit pointer is set to green, and upper limit pointer is set to redness, meets conventional caution color, and its good warning effect is guaranteed equipment in the situation that normal pressure is moved.
3, only need to install one additional with the axle sleeve of bound pointer between dial plate and transparent housing, need not change the original structure of pressure survey mechanism.
Description of drawings

Fig. 2 is the structural representation of alarming device;
In figure: 1-dial plate, 2-transparent housing, 3-reading pointer, 4-joint, 5-lower limit pointer, 6-upper limit pointer, 7-axle sleeve, 8-adjusting knob, 9-anchor post.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
as depicted in figs. 1 and 2, a kind of tensimeter with adjustable alarming device, it comprises dial plate 1, be sleeved on the transparent housing 2 of dial plate 1 outside, the reading pointer 3 that is connected with pressure survey mechanism and the joint 4 that is connected with pressure survey mechanism, it also comprises lower limit pointer 5, upper limit pointer 6 and axle sleeve 7, axle sleeve 7 bottoms are provided with anchor post 9, anchor post 9 is fixedly linked with the center of dial plate 1, the middle part of axle sleeve 7 is fixed with respectively lower limit pointer 5 and upper limit pointer 6, the top of axle sleeve 7 is fixed on the center of transparent housing 2 by nut, the top of axle sleeve 7 is provided with adjusting knob 8, adjusting knob 8 is the flute profile knob.
Wherein, lower limit pointer 5 is surperficial greeny pointer; The pointer that upper limit pointer 6 takes on a red color for the surface.
in the situation that do not change original pressure survey mechanism, the axle sleeve 7 with upper limit pointer 6 and lower limit pointer 5 is installed in center between dial plate 1 and transparent housing 2, and the bottom of axle sleeve 7 is fixed on dial plate 1 by anchor post 9, the top of axle sleeve 7 is fixed on transparent housing 2 by nut, axle sleeve 7 passes transparent housing 2, be provided with the flute profile knob in the end of axle sleeve 7, lower limit pointer 5 and upper limit pointer 6 can be transferred to the position that the pressure caution line need to be set with bottle opener, and the appearance of lower limit pointer 5 is set to green, the appearance of upper limit pointer 6 is set to redness, when reading pointer 3 points to regional between lower limit pointers 5 and upper limit pointer 6, expression pressure is normal, during lower than the numerical value of lower limit pointer 5 indications, expression pressure is on the low side when the reading of reading pointer 3, during higher than the numerical value of upper limit pointer 6 indications, expression pressure is higher when the reading of reading pointer 3.Be conducive to like this operating personnel and carry out whether normally judgement of pressure.
