Abstract
The utility model relates to a shock isolator for pressure gauge which solves the problem of the existing same product which has the function of shock absorption but the effect of isolation from tested medium, which results in frequent clogging and effects the test effect. The isolator which is positioned in the pressure chamber of the tested medium is closely connected with a damping body so as to achieve the purpose of isolating the tested medium. The product has the advantages of simple structure, good testing effect, long service life, etc.
Description
The utility model relates to the instrument shock attenuation device, and especially a kind of tensimeter is isolated shatter-proof device.
Existing pressure gauge snubber and general purpose pressure gauge be supporting to can be used for having the pressure measurement of fluctuation pressure occasion, normally adopt liquid to produce damping method and reach damping by elongated hole with certain viscosity, but it is difficult reasonably to determine with the processing slim hole, and shock-proof effect is not good, not only isolated in addition but also shatter-proof device is used for tensimeter, by retrieval, do not find yet.
The utility model purpose is: at the problems referred to above, provide a kind of simple in structure, not only have cushioning effect, and the tensimeter that measured medium can also be isolated from outside the damping body is isolated shatter-proof device.
The utility model is achieved in that the isolator that is positioned at the measured medium pressure chamber and its are full of fluid and link to each other with damping body sealing that pressure gage spring tube is communicated with.Promptly, measured medium is isolated from outside the damping damp channel of pressure gage spring tube by isolator.And the transmission of pressure is according to Pascal law: act on the measured medium pressure on the isolator, by in advance with the bourdon tube transmission of fluid in tensimeter that is full of in pressure gage spring tube, coupled damping body and the isolator.
Adopt the tensimeter of said structure to isolate shatter-proof device, its major advantage:
But 1, the liquid of measured medium different viscosities, gas and susceptible to plugging medium can not produce obstruction.
2, measured medium does not directly enter the damping slit, thereby the viscosity of measured medium and foreign material do not have influence to its shock-proof effect.After as long as design is set up before assembling, its shock-proof effect is just fixing.
3, have antifreeze fluid owing to being full of in Communicating device, this isolates shock-proof pressure gauge and can use in the open at north of china in winter.
4, owing to have and can not stop up, good shatter-proof characteristics of tool again, can improve greatly serviceable life.Be particularly suitable for air pump water pump boiler feed system; The hydraulic system of various stream press, water pressure engine, plastics machinery; Chemical industry, the big and susceptible to plugging occasion measuring pressure of drainage and the first-class vibrations of drilling mud pump.
Below in conjunction with description of drawings the utility model most preferred embodiment.
Accompanying drawing is the utility model outward appearance cut-away view.
In the accompanying drawings, oil storage chamber, 9 sealing gaskets, 11 top connections, 12 pressure gauge connections between 1 measured medium inlet, 2 lower subs, 3 measured medium pressure chambers, 4 corrugated tube isolators, 5 isolator oil storage chambers, 6 damping bodies, 7,10 jackscrews, 8 jackscrews.Among this embodiment, in the cavity of damping body 6 and the top connection 11 that is communicated with it, revolve top set silk 7 and 10 respectively, and between them, leave oil storage chamber 8, two jackscrews, 7,10 head and the tail collided to prevent the oil pressure effect.In addition, isolator 4 adopts corrugated tube in this example, and it can also be diaphragm or rubber diaphragm.
Its course of work of accompanying drawings:
When measured medium enters in the measured medium pressure chamber 3 by inlet 1, the pressure of its fluctuation transmits to damping body 6 by the fluid in the isolator 4, because jackscrew 7 in the damping body 6 and 10 damping action, make tested surge pressure reach damping shock absorption, then by with tensimeter that pressure gauge connection 12 connects in bourdon tube transmit pressure.Thereby make tensimeter reach the purpose of isolation, damping.
Claims (3)
1, a kind of tensimeter of screw-type damper that comprises is isolated shatter-proof device, its feature: be positioned at the isolator 4 of measured medium pressure chamber 3, link to each other with damping body 6 sealings.
2, tensimeter according to claim 1 is isolated shatter-proof device, its feature: in the cavity of damping body 6 and top connection 11 connections, revolve top set silk 7 and 10 respectively, and leave oil storage chamber 8 between them.
3, tensimeter according to claim 1 is isolated shatter-proof device, its feature: isolator 4 can be a corrugated tube, or diaphragm or rubber diaphragm.
