Description

Nuclear island Y shape adds pipe arrangement High Temperature High Pressure pressure-relief type Double-clack stop valve
Technical field
The utility model relates to stop valve field, is specifically related to a kind of nuclear island Y shape and adds pipe arrangement High Temperature High Pressure pressure-relief type Double-clack stop valve.
Background technique
Tradition stop valve is mainly used in the pipeline of the flowing such as vapour road, water route, oil circuit in the fields such as petrochemical industry, On The Oil And Gas Transportation, mine metallurgy, electric power, for connecting and blocking ducted medium, ensures the normal operation of equipment Pipe-Line.
The MEDIA FLOW of conventional stop valve is to being generally low in and high out, but this kind of MEDIA FLOW is to several shortcoming below existing for high pressure and the larger valve of bore: 1. poor sealing performance.2. operational torque is large.3. working life is short etc.
The stop valve being open-shut device with pressure-relief type Double-clack is widely used in unlatching or the closing control in the field such as nuclear island, electric power, has the series of advantages such as good seal performance, operational torque are little, long service life with traditional open-shut device design comparison.This project change in design MEDIA FLOW to, changed into " high in and low out " by original " low in and high out ", big valve flap increases relief hole, by controlling pressure and the flow of fluid, valve opening moment is reduced relatively, can relatively reduce valve rod size, also can reduce operation equipment specification, thus saved material, reduce cost.
Summary of the invention
