Description

Corrosion-prevention measuring instrument

Technical Field

The utility model relates to a measuring instrument of corrosion prevention belongs to the technical field of automatic instrument.

Background

The corrosive media are widely used in areas such as an ammonia area, water melting, a water collecting tank and seawater chlorine production areas of a thermal power plant, and the measuring instrument is corroded by various corrosive media, so that the service life of the measuring instrument is reduced, the replacement period is accelerated, and the purchasing cost and the maintenance cost are increased.

The prior art usually adopts bellows type manometer and changer to carry out pressure measurement to the equipment in corrosion zone, can satisfy anticorrosive requirement in bellows type manometer and the changer short time, nevertheless because bellows type measuring instrument moves the back for a long time, the measurement deviation appears, has the check-up difficulty, can't guarantee measured data accuracy to bellows type measuring instrument in case the bellows damages, because of the bellows area of contact is great, the on-the-spot volume of revealing is great, and the isolation is difficult, threatens personal safety.

The measuring instrument of the prior art has the easy scheduling problem that corrodes, consequently, the utility model provides a measuring instrument that prevents corrosion is used for solving above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior measuring instrument such as corrosion, the utility model relates to a corrosion-proof measuring instrument, which has simple structure and effectively prevents the measuring instrument from being corroded.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent measuring instrument of corruption, includes that manometer and intercommunication are at the connecting pipe by on the sampling equipment, the manometer sets up in the connecting pipe and keeps away from the below by sampling equipment one side, be provided with the U-shaped pipe between manometer and the connecting pipe, the U-shaped pipe setting just is vertical setting in the connecting pipe below, U-shaped pipe one end and manometer intercommunication, the one end intercommunication by the sampling equipment is kept away from to the other end and connecting pipe, the intraductal grease that is provided with of U-shaped.

And a sampling primary valve is arranged on the pipe section of the connecting pipe, and is a needle valve.

And a sampling secondary valve is arranged on the pipe section of the U-shaped pipe, and the sampling secondary valve is a needle valve.

And the inner walls of the U-shaped pipe and the connecting pipe are coated with anticorrosive paint.

The pressure gauge is fixedly provided with a connector at the bottom and is communicated with the U-shaped pipe through the connector.

Compared with the prior art the utility model discloses there are following characteristics and beneficial effect: the utility model avoids the corrosion medium from directly contacting the measuring instrument through the arrangement of the U-shaped pipe and the grease in the U-shaped pipe, thereby avoiding the instrument from being corroded and prolonging the service life of the instrument;

the utility model can avoid the long-time high-pressure practicality of the pressure gauge by arranging the sampling primary valve and the sampling secondary valve, and simultaneously, the pressure gauge of the utility model can be replaced and the applicability of the utility model is increased;

the utility model discloses a further increase at U-shaped pipe and connecting pipe inner wall application anticorrosive coating the utility model discloses an anticorrosive ability.
