Abstract
The utility model relates to a kind of Anti-seismic manometer flexible member, and it adopts hook switch structure, and described hook switch has base, step-shaped hole is shaped with in base, two symmetrical thin beams are arranged at base top, and thin back portion is thicker installation position, and installation position is shaped with mounting hole.What in the utility model, hook switch design adopted is the principle that beam stress is out of shape, the left and right sides is symmetrical, after concentrated force F acts on the center below hook switch, the beam of the inside and the beam of outside produce distortion simultaneously, the deflection of internal and external beam is different, but left and right sides is all by F/2 force action, both sides form outwardly angle α/2 simultaneously, after this displacement transfer to linkage magnification system, formation center corner α, such concentrated force F, by the distortion of hook switch, is indicated by scale with the form of angular displacement, thus achieves the function of instrument.
Description
Technical field
The utility model belongs to industrial automation instrument manufacturing technology field, is a kind of flexible member of shock-proof pressure gauge, compressive deformation in the shock-proof pressure gauge course of work, drive gear train, scale is turned round, and by the amplification of gear train, indicates the mean value of tested fluctuation pressure.Product is mainly applicable to measure liquid pulsation pressure, for the drilling-production equipment of the departments such as oil, coal, geology, also can be used to measure static pressure.
Background technology
Flexible member is the shock-proof pressure gauge of bourdon tube is widely used a kind of instrument in commercial production, there is good earthquake-proof function, be applicable to the situation that environment judder and pressure medium are acutely pulsed, measure the pressure without explosion danger, non-crystallizable, noncondensing liquid, gas or steam.The instruction of this instrument is stable, and clear reading, is widely used in the departments such as heavy-duty machinery, mine, oil, chemical industry, metallurgy, electric power.The flexible member (bourdon tube) of this kind of instrument and physical contact between media, thus can only be used for measuring non-crystallizable, noncondensing liquid, gaseous tension, cannot measure mud, cement etc. easily solidify and easily crystallization, full-bodied pressure medium.In order to expand the usable range of shock-proof pressure gauge, make it can be used on the special medium of performance, we have specially carried out structure improvement, be proposed the anti-shock pressure meter with " anti-blocking " feature, keep apart by medium and the flexible member in table, thus can measure mud, cement etc. easily solidify and easily crystallization, full-bodied pressure medium, the flexible member of this anti-shock pressure meter needs special construction.
Summary of the invention
The utility model is object is a kind of Anti-seismic manometer flexible member of design, is used in Anti-seismic manometer and experiences pressure, produce distortion, thus the part of reflection pressure.
Anti-seismic manometer flexible member, it adopts hook switch structure, and described hook switch has base, is shaped with step-shaped hole in base, and two symmetrical thin beams are arranged at base top, and thin back portion is thicker installation position, and installation position is shaped with mounting hole.
Utilize the Anti-seismic manometer of described hook switch, it is made up of housing, sealing gasket, diaphragm group, plunger tip, hook switch, linkage magnification system, watchcase, diaphragm group is installed on bottom sealing gasket in lower housing portion cavity and seals, plunger tip is equipped with on diaphragm group top, plunger tip upper end is inserted in the step-shaped hole in hook switch base, and installation position, hook switch top is connected with linkage magnification system.
What in the utility model, hook switch design adopted is the principle that beam stress is out of shape, the left and right sides is symmetrical, as shown in Figure 3-4, after concentrated force F acts on the center below hook switch, the beam of the inside and the beam of outside produce distortion simultaneously, the deflection of internal and external beam is different, but left and right sides is all by F/2 force action, both sides form outwardly angle α/2 simultaneously, after this displacement transfer to linkage magnification system, form center corner α, such concentrated force F is by the distortion of hook switch, indicated by scale with the form of angular displacement, thus achieve the function of instrument.

Embodiment
As Figure 1-4, Anti-seismic manometer flexible member, it adopts hook switch structure, described hook switch has base 5-1, step-shaped hole is shaped with in base 5-1, two symmetrical thin beam 5-2 are arranged at base 5-1 top, and thin beam 5-2 top is thicker installation position 5-3, installation position 5-3 is shaped with mounting hole 5-4.
After processing hook switch according to drawing, place storehouse, through the Ageing Treatment of half a year, after eliminating machining stress, can use.Assemble according to general assembly drawing, ensure the reasonable clearance of each parts; By the size of range, by the moment size of regulation, adopt torque spanner to tighten, ensure that each parts closely cooperate, so that effective transmission of power.Qualified instrument is become after adjustment.
As shown in Figure 5, utilize the Anti-seismic manometer of described hook switch, it is made up of housing 1, sealing gasket 2, diaphragm group 3, plunger tip 4, hook switch 5, linkage magnification system 6, watchcase 7, diaphragm group 3 is installed on bottom sealing gasket 2 in housing 1 lower cavity and seals, plunger tip 4 is equipped with on diaphragm group 3 top, plunger tip 4 upper end is inserted in the step-shaped hole in hook switch 5 base, and installation position, hook switch 5 top is connected with linkage magnification system 6.
Principle of work is: medium is not by nethermost rubber gasket transmission of pressure (medium directly enters in flexible member), diaphragm group is above by capillary channel current limliting principle, fluctuation pressure is suppressed to become more stable pressure, become concentrated force by plunger tip again and pass to hook switch, hook switch produces distortion under force, drive the gear train on hook switch, and then amplified by smooth pressure, the mean value of tested like this fluctuation pressure is just indicated by pivotal scale.
The utility model feature:
1) hook switch adopts round steel 30CrMnSiA processing, very high intensity and enough toughness is had after 30CrMnSiA is modified, there is good processability simultaneously, machining deformation is small, and anti-fatigue performance is fairly good, the part processed, through Wetted constructures, stable performance, is applicable to Long-Time Service, ensure that the total quality of product.
2) hook switch adopts the design concept of beam, stress equalization, and steadily, the linearity is good, is easy to adjustment in distortion.
3) instrument of this structure is isolated by rubber gasket, and medium cannot be entered in table, and due to cavity below comparatively large, make easily to solidify, medium that easily crystallization, viscosity are high etc. can flow out faster, decrease the possibility of blocking.
4), in fluctuation pressure transmittance process, by the capillary channel of diaphragm group, thus suppress for smooth pressure; Fill with in watchcase and rush full-bodied silicone oil, play the effect suppressing fluctuation pressure equally, thus this kind of instrument is more suitable for the violent occasion of fluctuation pressure.
5) this kind of instrument is filled with and is rushed full-bodied silicone oil, and weight is about about 5Kg, is more suitable for the occasion that environmental vibration is violent.
Common shock-proof pressure gauge is made up of joint, bourdon tube, gear drive, indicating device and watchcase, table cover, watch glass etc., this instrument is once bourdon tube breaks, pressure medium can enter in watchcase instantaneously, and hook switch formula anti-shock pressure meter medium is difficult to enter table inner chamber, thus safety coefficient is high, and use occasion is wider.
