Abstract

The utility model provides a chemical pipe valve which mainly consists of a metal pipe coated outside a through pipe, a corrosion-resistant plastic pipe built in the through pipe, a valve rod rotating handle, a metal pipe coated outside a valve rod pipe, a corrosion-resistant plastic pipe built in valve rod pipe, an isolator built in the valve rod pipe and a connecting flange coated outside the metal pipe. The chemical pipe valve is characterized in that the inner wall of the metal pipe coated outside the through pipe is provided with the corrosion-resistant plastic pipe built in the through pipe, the inner wall of the metal pipe coated outside the valve rod pipe is provided with the corrosion-resistant plastic pipe built in the valve rod pipe, a connecting opening between the corrosion-resistant plastic pipe built in the through pipe and the corrosion-resistant plastic pipe built in the valve rod pipe adopts thermal adhesion, the corrosion-resistant plastic pipe built in the valve rod pipe is internally provided with the isolator built in the valve rod pipe, and the metal pipe coated outside the through pipe is connected with the metal pipe coated outside the valve rod pipe by the connecting flange coated outside the metal pipe. The chemical pipe valve has the beneficial effects that corrosion resistance is achieved and the damage is unlikely to happen, the production comprehensive cost of a chemical factory can be reduced, the pipe valve is suitable for the chemical factory for a long term, and comprehensive cost performance is high.

Description

The chemical industry pipe valve

Technical field:

The utility model relates to the industry equipment technical field, refers in particular to a kind of chemical industry pipe valve.

Background technique:

Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve also is divided into cast iron valve according to material, cast steel valve, stainless valve, Cr-Mo steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, the nonstandard customized valve that waits.Chemical industry pipeline valve majority used is metal valve, and this valve compression resistance is strong, and safety coefficient is high, but, because it belongs to metallic material, as Chemical valve, still will produce chemical action, reduction of service life, and also price is also relatively expensive.

The model utility content:

The purpose of this utility model is to provide a kind of new-type chemical industry pipe valve, solve existing Chemical valve adopt the metal valve price high, easily the problem that chemical reaction is corroded occurs.

The purpose of this utility model realizes as follows: a kind of chemical industry pipe valve, mainly by siphunculus kalamein pipe, the built-in anti-rot plastic pipe of siphunculus, the valve rod swing handle, valve rod pipe kalamein pipe, the built-in anti-rot plastic pipe of valve rod pipe, the built-in partition of valve rod pipe, kalamein pipe flange connector forms, it is characterized in that: at siphunculus kalamein inner tube wall, be provided with the built-in anti-rot plastic pipe of siphunculus, be provided with the built-in anti-rot plastic pipe of valve rod pipe at valve rod pipe kalamein inner tube wall, the built-in anti-rot plastic pipe of siphunculus and the built-in anti-rot plastic interface tube of valve rod pipe place adopt hot adhesion, in the built-in anti-rot plastic pipe of valve rod pipe, the built-in partition of valve rod pipe is installed, in siphunculus kalamein pipe and valve rod pipe kalamein pipe joint, adopt kalamein pipe flange connector to be connected.

The beneficial effects of the utility model are: corrosion protection, and not fragile, chemical plant produces overall cost and reduces, and is suitable for chemical plant and uses for a long time, and comprehensive sexual valence is higher.

The accompanying drawing explanation:

Fig. 1 is the utility model structural representation.

In figure, siphunculus kalamein pipe 1, the built-in anti-rot plastic pipe 2 of siphunculus, valve rod swing handle 3, valve rod pipe kalamein pipe 4, the built-in anti-rot plastic pipe 5 of valve rod pipe, the built-in partition 6 of valve rod pipe, kalamein pipe flange connector 7.

Embodiment:

With reference to Fig. 1, a kind of chemical industry pipe valve, mainly by siphunculus kalamein pipe 1, the built-in anti-rot plastic pipe 2 of siphunculus, valve rod swing handle 3, valve rod pipe kalamein pipe 4, the built-in anti-rot plastic pipe 5 of valve rod pipe, the built-in partition 6 of valve rod pipe, kalamein pipe flange connector 7 forms, be provided with the built-in anti-rot plastic pipe 2 of siphunculus at siphunculus kalamein pipe 1 inwall, be provided with the built-in anti-rot plastic pipe 5 of valve rod pipe at valve rod pipe kalamein pipe 4 inwalls, the built-in anti-rot plastic pipe 2 of siphunculus adopts hot adhesion with built-in anti-rot plastic pipe 5 jointings of valve rod pipe, the built-in partition 6 of valve rod pipe is installed in the built-in anti-rot plastic pipe 5 of valve rod pipe, in siphunculus kalamein pipe 1 and valve rod pipe kalamein pipe 4 joints, adopt kalamein pipe flange connector 7 to be connected.
