How much knowledge do you have about BURKERT angle seat valves in Germany?
Many people will ask what the function of pneumatic angle seat valve is when they see the German BURKERT angle seat valve? In fact, pneumatic angle seat valves have many uses, such as maintaining flow rate and saving space. They use a single acting pneumatic actuator with spring safety protection to operate the guide angle seat valve. When using, it should be selected as normally open or normally closed. Let's take a detailed look below.
1. The German BURKERT angle seat valve can maintain flow rate and save space It adopts a single acting pneumatic actuator with spring safety protection to operate the guide angle seat valve When using, one should choose between normally open or normally closed.
2. The German BURKERT angle seat valve is widely used for short-term frequent starting, with the characteristics of sensitive response and accurate action. When used in conjunction with solenoid valves, it can accurately control gas and liquid flow rates through pneumatic control. It can meet the requirements of accurate temperature control and liquid dripping.
By using the action of a spring to push the valve stem, the valve can be controlled to open or close; The sealing part of the guide angle seat valve is operated by a single acting or double acting pneumatic actuator inside the cylinder. Choose the normally open or normally closed setting when using. The valve body of pneumatic steam valves is generally cast from stainless steel and copper materials, and the sealing material is made of polytetrafluoroethylene or high temperature resistant materials; It can be used for the circulation of most gases, liquids, vapors, and corrosive materials. It comes with a radiator to protect the actuator and ensure that the steam valve has a long service life.
Single acting and double acting principles of BURKERT angle seat valve:
The working principle of single action; Pneumatic heads are usually a hole, which can be divided into normally open and normally closed types based on the spring reset to achieve opening and closing.
Double acting working principle: The pneumatic head usually has two holes, which are controlled by the air source to open or close the valve.
BURKERT angle seat valves and medical equipment, chemical, high-temperature sterilization, foaming machinery, water treatment equipment, etc. The main connection methods include thread, flange, welding, and clamp connection. Widely applicable, high cost-effectiveness, and long service life.
1. The poor processing of the sealing surface is mainly manifested by defects such as cracks, pores, and inclusions on the sealing surface, which are caused by improper selection of welding and heat treatment specifications and poor operation during welding and heat treatment. The high or low hardness of the sealing surface is caused by improper material selection or heat treatment. The uneven hardness and corrosion resistance of the sealing surface are mainly caused by blowing the underlying metal onto it during welding, diluting the alloy composition of the sealing surface. Of course, there are also design issues involved here.
2. Damage caused by improper selection and poor operation. This is mainly manifested in the failure to select valves according to operating conditions, using block valves as throttling valves, resulting in excessive closing pressure, rapid or lax closing, and erosion and wear of the sealing surface. Improper installation and inadequate maintenance resulted in the sealing surface not functioning properly, causing the valve to operate with defects and prematurely damaging the sealing surface.
3. Chemical corrosion of the medium, the medium around the sealing surface directly interacts with the sealing surface without generating current, corroding the sealing surface. Electrochemical corrosion, contact between sealing surfaces, contact between sealing surfaces and closing bodies and valve bodies, as well as differences in medium concentration and oxygen concentration, can all generate potential differences, leading to electrochemical corrosion and corrosion of the sealing surface on the positive side.
4. The erosion of the medium is the result of the wear, erosion, and cavitation of the sealing surface during the flow of the medium. At a certain speed, the floating fine particles in the medium collide with the sealing surface, causing local damage. The high-speed flowing medium directly flushes the sealing surface, causing local damage. When the medium mixes and vaporizes locally, bubbles burst and impact the sealing surface of the sampling valve, causing local damage. The erosion of the medium combined with the alternating effect of chemical corrosion will corrode the sealing surface.
5. Mechanical damage can cause scratches, bumps, and squeezes on the sealing surface during opening and closing. Atomic permeation occurs between two sealing surfaces under high temperature and pressure, resulting in adhesion. When the two sealing surfaces move towards each other, the adhesive area is prone to tearing. The higher the surface roughness of the sealing surface, the more likely this phenomenon is to occur. During the closing process of the valve and the reseating process of the valve disc, the sealing surface may be damaged or squeezed, causing local wear or indentation on the sealing surface.
6. Fatigue damage occurs when the sealing surface is subjected to alternating loads during long-term use, resulting in fatigue, cracking, and delamination of the sealing surface. Rubber and plastic are prone to aging and deterioration after long-term use.
From the analysis of the causes of sealing surface damage above, it can be seen that in order to improve the sealing surface and service life of the valve, it is necessary to select appropriate sealing surface materials, reasonable sealing structures and processing, operation and maintenance methods
Manufacturing is a crucial project, so what is the process of manufacturing pneumatic angle seat valves? The following is a detailed introduction to the manufacturing process of pneumatic angle seat valves:
1. BURKERT angle seat valve consists of a valve body and accessories, and there are various materials available in the market to make it;
The manufacturing process of BURKERT angle seat valves involves the preparation of stainless steel elements, which are melted into liquid form at high temperatures and modeled using silica sol.
