What is the difference between exhaust valve well and sludge valve well

1、 The two have different purposes

1. Purpose of exhaust valve well: for the valves of underground pipelines and underground pipelines (such as tap water, oil, natural gas pipelines, etc.), a pit (or well) similar to a small room is set to facilitate the opening and closing of some pipe networks or maintenance operations.

2. Purpose of sludge discharge valve well: install and arrange valves in this pit to facilitate regular inspection, cleaning and dredging of pipelines and prevent pipeline blockage.

2、 The composition and classification of the two are different

1. Composition classification of exhaust valve well: the composition classification of exhaust valve well includes micro exhaust valve, composite exhaust valve and sewage composite exhaust valve.

2. Composition and classification of sludge discharge valve well: hydraulic control valve is a valve controlled by water pressure. Hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes, functions and places, it can be developed into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc.

3、 The requirements of the two are different

1. Requirements for exhaust valve well: the connection mode of valve well shaft, well body and well cover shall be reliable, and water shall not seep into the well chamber due to heavy rain or ponding. The valve well is buried underground, which should bear different pressures from all directions, corrosion and infringement of different chemicals, and its pressure bearing capacity and acid and alkali corrosion resistance are required to be good.

2. Requirements for sludge discharge valve well: the valve well itself cannot leak water, and its tightness must be guaranteed. Cast iron valves (such as stop valves, butterfly valves, etc.) are generally used when the buried valve well pipeline is slightly large. The long-term immersion of cast iron valves in water will affect their service life or cause fracture, so the requirements for sealing are higher.
