Abstract
The utility model relates to a liquid level meter which comprises a quartz glass tube and cocks on both ends thereof. The inner surfaces of the cocks and a medium contact member and the sealing surface of a connecting flange are lined with fluorine materials, and the utility model has the advantages of strong corrosion resistance. The utility model is a liquid level indicating device which can be suitable for strong acid containers, strong alkali containers and strong oxidant containers.
Description
Technical field
The utility model relates to a kind of liquid level gauge.The utility model is applicable to the level instruction device on the liquid medium container.
Background technology
Liquid level gauge is an indispensable position indicator on the liquid medium container of industries such as oil, chemical industry, environmental protection, iron and steel, generating, general by two cocks that are installed in the container upper and lower sides respectively, and be connected two quartz glass tubes between the cock and form, cock is made up of joint flange, valve and quartz glass tube installing port, after opening the valve of cock up and down, can show liquid level the container from quartz glass tube.Yet the cock of existing liquid level gauge is to be made by metal material, and major defect is a poor corrosion resistance, can not be applicable on the container of strong acid, highly basic, strong oxidizer medium.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of strong acid, highly basic, lining fluorine liquid level gauge strong oxidizer, that corrosion resistance is strong of being applicable to is provided.
The technical scheme of realization the utility model purpose comprises the cock at quartz glass tube and two ends thereof, mainly is the inside surface of cock and medium contact component and the sealing surface lining fluorine material of joint flange.
In above technical scheme, described fluorine material is a perfluoroethylene-propylene.
Preferably, backing layer thickness is 2mm.
The utility model beneficial effect compared with prior art is the sealing surface lining fluorine material at the inside surface of cock and medium contact component and joint flange, has the strong advantage of corrosion resistance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure cut-away view of cock among the utility model Fig. 1.
Embodiment
Now further describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments.
Lining fluorine liquid level gauge as shown in Figure 1, structure comprises the cock at quartz glass tube 7 and two ends thereof.Cock is made of stopcock, and as shown in Figure 2, the faucet body of stopcock and valve rod 5 manufacture one.At the passage lining fluorine material 4 that valve body 2 contacts with medium, the outside surface lining fluorine material 6 of faucet body and valve rod 5, the sealing surface lining fluorine material 2 of flange 1.Described fluorine material is perfluoroethylene-propylene (F46), and backing layer thickness is preferably 2mm.Perfluoroethylene-propylene (F46) backing layer adopts precompressed sintering process sintering on the metalwork surface.
