Description
Technical field
The present invention relates to a kind of tensimeter, be specifically related to a kind of anti-shock pressure meter.
Background technology
It is sensitive element that tensimeter refers to flexible member, measures and indicates the instrument higher than environmental pressure, and application is very general, and it is almost throughout 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 stokehold and commercial measurement process, the elastic sensing element due to mechanical compression table has very high physical strength and the characteristic such as convenient for production, makes mechanical compression table obtain applying more and more widely.
The Chinese patent patent No. is CN201410830654.7, discloses a kind of tensimeter, and comprise bourdon tube, gear drive, registration device and shell, bourdon tube is connected with registration device by gear drive.This kind of tensimeter, its movement is that multiple gear and multiple connecting rod assembly form, its complex structure, produces and is provided with certain difficulty, and when the pipeline installing its measured medium trembles, easily there is elastic deformation in bourdon tube, can cause gear or connecting rod generation relative motion, cause indicator to rotate, stability extreme difference, of long duration, gear or the connecting rod of tensimeter inside easily misplace, and cause tensimeter to damage.
Summary of the invention
The object of the present invention is to provide the anti-shock pressure meter that a kind of structure is simple, anti seismic efficiency is good.
Technical scheme of the present invention is: anti-shock pressure meter, comprise shell, described shell has medium entrance, and shell is provided with driving stem, driving stem is provided with pointer, driving stem is plugged in medium entrance, is provided with spring between driving stem and shell, and driving stem is fixedly connected with register pin, driving stem is arranged with sleeve, sleeve is installed on shell, and sleeve has threaded hole, and register pin is located in threaded hole.
Beneficial effect of the present invention is: measured medium enters into enclosure by medium entrance, first measured medium contacts driving stem, and certain pressure is applied to driving stem, the elastic force that driving stem overcomes spring moves to the direction away from medium entrance, and driving stem is fixedly connected with register pin, and register pin can move along the threaded hole on sleeve, and rotate with driving stem, driving stem rotates and drives indicators turn, thus measures the pressure of measured medium, and now spring is in the state of compression or stretching.
When the pressure of measured medium reduces, spring will resilience, and move near the direction of medium entrance with driving stem, register pin is along the threaded hole counter motion on sleeve, and rotate backward with driving stem, driving stem rotates and drives indicators turn, thus measures the pressure after measured medium reduction.
Compared with prior art, the pressure of this tensimeter mainly through measured medium and the cooperation of spring, driving stem is moved up and down, and make driving stem do reciprocal rotation by register pin and threaded hole, this pressure meter structure advantages of simple, matching relationship is few, and register pin and threaded hole coordinate transmission to have good transmission stability, make when the pipeline installing its measured medium trembles, not easily there is elastic deformation in driving stem and sleeve, the position of register pin in threaded hole not easily changes, tensimeter anti seismic efficiency is good, also be not easy to damage, in addition, this kind of drive is without the need to the lever construction of complexity or gear structure, reduce the volume that pressure becomes, applicability is strong.
Further: shell is fixedly connected with inner casing, inner casing is rotatably connected to rotating cylinder, and driving stem is set in rotating cylinder away from one end of sleeve, driving stem and rotating cylinder spline joint, and pointer to be located on rotating cylinder and to be positioned at above inner casing.When driving stem pumps, and when rotating, driving stem can debouch rotating cylinder, driving stem and rotating cylinder spline joint, driving stem can rotate relative to inner casing with rotating cylinder, but can not move up and down with rotating cylinder, rotating cylinder rotates with pointer, pointer to be located on rotating cylinder and to be positioned at above inner casing, index dial can be convenient to be arranged between pointer and rotating cylinder, thus measure the pressure of measured medium.
Further: sleeve is provided with gag lever post symmetrical centered by driving stem, and gag lever post and driving stem are slidably connected.The setting of gag lever post, can making driving stem when moving, can not shake.
Further: being positioned at above sleeve fixed-link on driving stem has two connecting rods symmetrical centered by driving stem, and described spring is two, and being arranged between connecting rod and shell of two spring symmetries.The setting of two springs, can play the effect of spacing driving stem, and make it when moving, its left and right sides stressed more stable, avoids it to shake.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of anti-shock pressure meter embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: shell 1, medium entrance 2, outer casing screw 3, inner casing 4, spring 5, sleeve 6, threaded hole 7, connecting rod 8, rotating cylinder 9, pointer 10, driving stem 11, register pin 12.
