Abstract

The utility model discloses a curved pipe manometer, which belongs to the technical field of the manometer and comprises a manometer and a curved pipe. The manometer is connected with one end of the curved pipe; the curved pipe is provided with at least a loop of screw bend; the manometer is spirally connected with one end of the curved pipe; the other end of the curved pipe is provided with a connection head; the curved pipe is a copper pipe or a stainless steel pipe; the curved pipe is poured with liquid pressure-passing medium; the inside of the curved pipeline is poured with the liquid pressure-passing medium so as to form the curved pipe manometer; the liquid pressure-passing medium is used as intermediate medium to pass the pressure, thereby avoiding the tested liquid matter directly from entering to the inside of the curved pipe manometer and destroying the curved pipe manometer and preventing the curved pipe manometer from blockage to influence the measured data.

Description

A kind of bent type pipe pressure meter

Technical field:

The utility model relates to the pressure gauge technical field, particularly a kind of bent type pipe pressure meter.

Background technology:

The common fluid pressure gauge is to utilize the pointer of the elastic webbing dynamic pressure meter of metal tube to measure fluid pressure.If measure the liquid that solidifies easily, as glue, resin or the like, it can produce several drawbacks: the firstth, and glue condenses in metal tube, and it is later on unrenewable to make that pressure gauge uses once; The secondth, glue pollutes pressure gauge surface and inner easily, causes reading unintelligible; The 3rd is the inside and outside glue of cleaning pressure meter, needs to use the polar solvent of acetone and so on, and the dial plate of the organic glass of damaging surface, even infiltration easily clings pointer, causes read untrue.

The utility model content:

The purpose of this utility model is to provide a kind of bent type pipe pressure meter at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme:

A kind of bent type pipe pressure meter comprises tensimeter and bent type pipe, and tensimeter is connected with an end of bent type pipe.

Described bent type pipe is at least one circle helical buckling.

One end of described tensimeter and bent type pipe is spirally connected.

The other end of described bent type pipe has connector.

Described bent type pipe is copper pipe or stainless-steel tube.

Be perfused with the liquid pressure transmitting medium in the described bent type pipe.

The utility model beneficial effect is: a kind of bent type pipe pressure meter, pour into the liquid pressure transmitting medium in bent type pipeline the inside, form bent type pipe pressure meter, utilize the liquid pressure transmitting medium to transmit pressure as intermediary, thereby avoid the fluid to be measured material directly to enter bent type pipe pressure meter inside, stop up bent type pipe pressure meter, influence measurement data; Therefore first is stopping of liquid pressure transmitting medium, and the fluid to be measured material can directly not enter bent type pipe pressure meter inside, can not stop up bent type pipe pressure meter, can play the effect of the bent type pipe pressure meter of protection, guarantees the accurate of data.The secondth, the liquid pressure transmitting medium can slowly volatilize at normal temperatures, air pressure under the normality in the pipe can be greater than the outer air pressure of pipe, and when bent type pipe pressure meter left unused, the remaining fluid to be measured material in the pipe can be discharged automatically because of this pressure reduction, can avoid the situation of line clogging, guarantee the accurate of data; The 3rd is the distance that pipeline has increased tensimeter and equipment, and the probability that makes tensimeter polluted by the fluid to be measured material reduces; The 4th is that the liquid pressure transmitting medium exists in bend pipe inside for a long time, and long service life need not often be changed the liquid pressure transmitting medium in the bend pipe.

Description of drawings:

Fig. 1 is the structural representation of utility model

Embodiment:

A kind of bent type pipe pressure meter comprises tensimeter 1 and bent type pipe 2, and tensimeter 1 is connected with an end of bent type pipe 2; Described bent type pipe 2 is at least one circle helical buckling; Described tensimeter 1 is spirally connected with an end of bent type pipe 2; The other end of described bent type pipe 2 has connector 3; Described bent type pipe 2 is copper pipe or stainless-steel tube; Be perfused with the liquid pressure transmitting medium in the described bent type pipe 2.

Pour into acetone soln in bent type pipe 2 pipelines the inside, tensimeter 1 is spirally connected with an end of bent type pipe 2, form bent type pipe pressure meter, and bent type pipe 2 is the copper pipe of a circle helical buckling, utilize acetone soln to transmit pressure as intermediary, thereby avoid the fluid to be measured material directly to enter bent type pipe pressure meter inside, stop up bent type pipe pressure meter, influence measurement data.The connector 3 of bent type pipe 2 other ends is connected with the equipment of fluid to be measured, under the stopping of acetone soln, the fluid to be measured material can directly not enter bent type pipe pressure meter inside, can not stop up bent type pipe pressure meter, can play the effect of the bent type pipe pressure meter of protection, guarantee the accurate of data; Acetone soln can slowly volatilize at normal temperatures, air pressure under the normality in the pipe can be greater than the outer air pressure of pipe, and when bent type pipe pressure meter left unused, the remaining fluid to be measured material in the pipe can be discharged automatically because of this pressure reduction, can avoid the situation of line clogging, guarantee the accurate of data; Pipeline has increased the distance of tensimeter 1 and equipment, and the probability that makes tensimeter 1 polluted by the fluid to be measured material reduces; In the inner existence of bend pipe, long service life need not often be changed the acetone soln in the bend pipe to acetone soln for a long time.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
