Abstract
The utility model relates to a connecting pipe and a bourdon spring of an anticorrosive and antifreezing pressure gauge, which comprises a bourdon spring (1), a sealing head (3), an upper connecting pipe (4) and a lower connecting pipe (7). The utility model is characterized in that anticorrosive liquid (5) is filled in the connecting pipe and the bourdon spring (1), the sealing head (3) at the tail end of the bourdon spring (1) is provided with a small air hole (2), and the contact point of the interior of the lower connecting pipe (7) and the lower end of the upper connecting pipe (4) is provided with a film isolating device (6). The connecting pipe and the bourdon spring of the pressure gauge overcomes the problem of inaccurate measure in a pressure measuring process in the prior art caused by the corrosive function of measured process media entering the connecting pipe and the bourdon spring of the pressure gauge, and also overcomes the problem of inaccurate pressure measure because measured process media can solidify in pipes.
Description
Technical field
The utility model relates to a kind of anticorrosion, anti-freeze pressure meter adapter and bourdon tube
Background technology
The bourdon gauges of prior art, its manometric adapter and bourdon tube are hollow tubular, when not using, be full of air in the pipe, in process with the tested processing medium of gauge measurement, because the temperature in the tensimeter of tested front and back all is approximately equal to environment temperature, therefore, the pressure mechanism is similar to isothermal process, and pressure (P) is the PV=constant with the pass of the volume (V) that air occupies, so pressure is big more, the whole process that air occupies is more little, measured medium can enter in gauge manifold and the bourdon tube, and gauge manifold and bourdon tube are all had corrosive attack, causes pressure measurement inaccurate; In addition, the solidifying point of measured medium, if when being higher than environment temperature, then measured medium easily in gauge manifold and bourdon tube, solidify cause measure inaccurate.
The utility model content
The purpose of this utility model is to provide a kind of prior art medi-spring hook gauge tested processing medium in the pressure measurement process that can solve to enter and play corrosive attack in gauge manifold and the bourdon tube and cause the inaccurate and measured medium of pressure measurement to be easy to solidify two problems that cause pressure measurement inaccurate in pipe.For achieving the above object, this anticorrosion, anti-freeze pressure meter is taken over and the formation of bourdon tube is, adapter is formed by being threaded by upper connecting tube and lower linking tube, upper connecting tube links to each other with the annular elastomeric reed pipe that its end is equipped with seal head, make to take over and communicate with bourdon tube, be characterized in, be full of anticorrosion liquid in adapter and the bourdon tube, one spilehole is arranged on the seal head of bourdon tube end, in the lower linking tube part that links to each other with the upper connecting tube lower end barrier film device is housed, one of formation of this barrier film device is that snap ring is placed on the barrier film, barrier film places on the deck, on deck, the lower end also is equipped with sealing gasket respectively independently; Two of formation is that snap ring places on the barrier film, and barrier film places to have on the externally threaded deck, in the deck upper end one sealing gasket is arranged.
This anticorrosion, anti-freeze pressure meter are taken over and bourdon tube, owing in taking over and in the bourdon tube, be full of anticorrosion liquid, when pressure changes, liquid volume changes much smaller than changes in air volume, therefore, take over and bourdon tube in full of liquid can prevent measured medium enter take over and bourdon tube in, prevented measured medium corrosion adapter and bourdon tube and cause pressure measurement to be forbidden, and prevented measured medium from bourdon tube, solidifying and the problem that causes pressure measurement to be forbidden.Therefore, the utility model has the advantages that:
1, measured medium does not directly contact with pressure gage spring tube, can avoid the corrosion of tested processing medium to pressure gage spring tube, has improved the accuracy and the manometric serviceable life of pressure measurement.
2, tested processing medium does not enter gauge manifold and bourdon tube, and tested processing medium can not solidify in tensimeter.

Embodiment
Narrate the embodiment of this anticorrosion, anti-freeze pressure meter adapter and bourdon tube with reference to the accompanying drawings, can adopt welding or gluing connecing between bourdon tube 1 end and the seal head 3, its intensity will satisfy the pressure needs, spilehole 2 on the seal head 3 can be threaded hole or other spilehole, also can weld a small tubes, should be in the tensimeter use with spilehole 2 sealings.The effect of spilehole is that when upper connecting tube 4 and bourdon tube 1 filling liquid, gas in the vent pipe should seal spilehole after liquid is filled.Bourdon tube 1 other end and upper connecting tube 4 link up by welding, but bourdon tube communicates with upper connecting tube, lower linking tube 7 and upper connecting tube 4 are by being threaded, the part that contacts with upper connecting tube 4 lower ends in lower linking tube 7 is equipped with the barrier film device that is made of snap ring 8, sealing gasket 11, barrier film 9, deck 10 as shown in Figure 2, being about to snap ring 8 places on the barrier film 9, barrier film 9 places on the deck 10, and sealing gasket 11 is installed in deck 10 upper and lower sides respectively.The another kind of version of barrier film device as shown in Figure 3, promptly snap ring 8 places on the barrier film 9, barrier film 9 places to have on the externally threaded deck 10, in deck 10 upper ends one sealing gasket 11 is arranged.This barrier film device is connected with lower linking tube 7 by the external thread of deck 10, and is easy for installation.Barrier film device 6 is used to isolate tested processing medium and bourdon tube and takes over interior liquid, barrier film will have certain surface area and easily deformable, barrier film both sides pressure difference is not more than 1/10 of tensimeter precision, the liquid that fills in adapter and the bourdon tube, preferably flowability is not too strong, but the pseudoplastic fluid that not just can flow by small shearing force, as butter etc.
