In summer,the medium inside the storage tank evaporates due to heat,and the sudden increase in pressure may cause the tank to crack.The sudden drop in temperature at night in winter and the negative pressure inside the tank can easily cause the tank to collapse-the risk of pressure imbalance in the storage tank is always lurking in industrial storage scenarios.
The stainless steel breather valve is precisely the core equipment to solve this pain point:it automatically regulates the pressure difference inside and outside the tank,and at the same time,with the corrosion resistance and durability of stainless steel,it is suitable for complex working conditions such as acids,alkalis,and high humidity,ensuring the long-term safe operation of the storage tank with low maintenance costs. Compared with other types of stainless valve,it is more specialized in tank pressure balance regulation,while some heavy-duty industrial scenarios also complement the pressure control system with stainless steel gate for double protection.
The stainless steel breather valve is a safety device installed on the top of the storage tank,made of stainless steel.Its function is to automatically adjust the pressure balance inside and outside the storage tank,preventing deformation and damage to the tank due to overpressure or negative pressure,and at the same time reducing the evaporation loss of the medium.
Its working logic is centered around the pressure difference between the inside and outside of the storage tank.
When the medium inside the storage tank evaporates and the internal pressure rises to the preset positive pressure value specified in the breather valve specification,the positive pressure valve disc of the breather valve will be pushed open,and the excess gas inside the storage tank will be discharged outward,thereby reducing the internal pressure and preventing the storage tank from being damaged due to excessive pressure.When the medium inside the storage tank decreases or the external temperature drops,causing the internal pressure to drop and reaching the preset negative pressure value,the negative pressure valve disc will be pushed open by the external atmospheric pressure,allowing external air to enter the storage tank to balance the negative pressure inside and prevent the tank from being sucked in.
Stainless Steel’s Unique Advantages
The surface of stainless steel forms a stable oxide protective film,which can resist the erosion of most acids,alkalis,water vapor and corrosive media,and is not prone to rust,maintaining its own structural integrity.
The material structure of stainless steel itself is stable,with strong hardness and toughness.It can withstand certain external force impacts and pressure changes,and is not prone to deformation or fracture even after long-term use.
Stainless steel has strong stability and is not prone to damage or rusting.It does not require special maintenance operations on a daily basis.Just simple cleaning is enough to maintain a good usage condition.
The surface of stainless steel is smooth and has a low porosity,making it less prone to adhering,retaining stains and bacteria.At the same time,it does not release harmful substances,thus maintaining the cleanliness of the usage environment and the medium it comes into contact with.
A breather valve is a type of valve used to regulate the pressure inside and outside a container.Its main function is to balance the positive and negative pressure of the container,prevent damage to the container due to abnormal pressure,and at the same time reduce the evaporation of the medium inside the container.
It is a breathing valve made of stainless steel,retaining the pressure regulation function of the breathing valve while also having the material advantages of stainless steel,and can operate stably in special working conditions.
It is a ball valve made of stainless steel.The opening and closing of the valve are achieved by the rotation of the ball around the axis of the valve stem.Its main function is to cut off or connect the medium in the pipeline.
It is a check valve made of stainless steel,also known as a one-way valve.It only allows the medium to flow in one direction and can prevent the medium in the pipeline from backflowing,protecting the equipment in the pipeline.
The solenoid valve made of stainless steel controls the opening and closing of the valve by the electromagnetic force generated by the electromagnetic coil.It is mostly used in automated pipeline systems to control the on-off of the medium.
Regularly clean the valve port and sealing surface to remove residual medium impurities,dust and other dirt,to prevent impurities from adhering and causing poor sealing or stuck opening of the valve port, and ensure the normal sealing performance and regulating function of the valve.After cleaning,it is necessary to check the integrity of the sealing surface and remove the residual water in time.
Continuously monitor the composition of the medium flowing through the valve to confirm the compatibility of the medium with the valve material.To prevent damage to the valve material due to changes in the medium’s properties,if incompatible media are found,measures such as replacing the valve or adjusting the medium should be taken promptly.
Monitor the pressure changes in the storage tank in real time to prevent sudden rises and falls in pressure.By reasonably controlling the inflow and outflow of the medium and regulating the ambient temperature,the pressure can be maintained within the preset safe range,reducing the wear of the valve caused by frequent start-stop or high-pressure impact and extending its service life.
Conduct a comprehensive inspection of the valve at the preset cycle,including the wear and deformation of core components such as the valve disc,spring,and seals,and confirm the tightness of component connections. Lubricate and maintain the moving parts, and replace the aged seals.At the same time,verify the valve pressure opening threshold to ensure it is consistent with the design requirements,and keep good maintenance records for archiving.
When a valve blockage is detected,immediately stop the relevant medium transportation operations and isolate the valve area.Remove the blockage by disassembling and cleaning,high-pressure purging and other methods. If the components are damaged,replace them in time. After the handling is completed,conduct a pressure test to confirm that the valve function has returned to normal,identify the cause of the blockage and take preventive measures.
When a leakage occurs,quickly close the associated valves upstream and downstream to cut off the source of the leakage and set up a warning area.Check for leakage points.If it is due to aging of the sealing parts or loose connections,replace the sealing parts in time and tighten the connecting parts.If the valve body is damaged,the valve needs to be replaced.After processi
ng,conduct a sealing test to ensure there is no leakage before resuming operation.
When making a selection,it is necessary to ensure that the specifications match,verify that the nominal diameter is consistent with the interface of the pipeline,and guarantee the installation and circulation efficiency.Confirm that the positive and negative pressure opening values match the design pressure of the storage tank,and at the same time,match the connection method,working temperature and other parameters to ensure compatibility with the system.
The corrosion resistance is evaluated in combination with the characteristics of the medium and the usage environment.For corrosive medium working conditions,high-grade stainless steel such as 316L is selected.In outdoor damp and high-salt spray environments,attention should be paid to the anti-corrosion treatment of valves to ensure that the corrosion resistance parameters of the material match the medium and avoid rusting and failure.
