Abstract
The utility model relates to a take stop valve of reserve valve, including valve body, valve clack, valve rod, valve gap, hand wheel, characterized by sets up two stop valves in valve bodies, wherein stop valves drop into normal operating condition, and stop valves are in normally open state in addition, and when the stop valve that is in operating condition broke down, stop valves drop into work in addition, keep pipe-line system continuous operation, saved bypass pipe-line system, saved erection equipment, have installation space, advantage such as with low costs.
Description
Technical Field
The utility model belongs to valve field especially relates to stop valves the utility model is suitable for an A level pipe-line system such as hydrogenation, chlorine.
Background
In A-stage pipeline systems of hydrogenation, chlorine and the like, because a medium pipeline is not allowed to stop working, a multi-line pipeline is adopted for conveying a medium in a common way, when a valve fails, a bypass pipeline is opened, and the valve is overhauled under the condition of normal medium conveying.
Disclosure of Invention
The utility model discloses to prior art's shortcoming, provide kinds of equipment fixing space little, the low stop valve of taking the spare valve of installation cost.
The technical scheme of the utility model including the valve body, the valve clack, the valve rod, the valve gap, the hand wheel, characterized by has disk seat and second valve seat at the valve body inner chamber system, the valve clack includes valve clack and second valve clack, the valve rod includes 0 valve rod and second valve rod, the valve gap includes valve gap and second valve gap, the hand wheel includes hand wheel and second hand wheel, disk seat and valve clack, valve rod, valve gap, the stop valve is constituteed to hand wheel, second disk seat and second valve clack, the second valve rod, the second valve gap, the second hand wheel constitutes the second stop valve.
In the above technical scheme, the th valve seat outlet is communicated with the valve body outlet channel, the inlet is communicated with the second valve seat outlet, and the second valve seat inlet is communicated with the valve body inlet channel.
In the above solution, the th valve seat is concentrically arranged with the second valve seat.
The beneficial effects of the utility model are that set up two stop valves in valve bodies, wherein stop valves drop into normal operating condition, and stop valves are in normally open state in addition, and when the stop valve that is in operating condition broke down, stop valves drop into work in addition, keep pipe-line system continuous operation, have saved bypass pipe-line system, have saved the erection equipment, have installation space, advantage such as with low costs.
