    The spring relief valve is mainly composed of spool, seat, stem, spring and adjusting screw.The relief valve mainly USES spring force to press the spool on the seat.When the boiler pressure exceeds the pressure exerted by the spring on the upper part of the spool, the spool and stem are lifted and steam is discharged.When the boiler pressure is lower than the spring pressure acting on the upper part of the spool, the spool falls on the seat and the boiler stops discharging steam.The spool is a cone with a slight protrusion around the edge of the spool.When the steam opens the valve core, the edge of the valve core is also affected by steam pressure, which makes the whole area of action increase suddenly, and the valve opens when the valve stops.When the drop force is reduced, the steam for...

    The corrosion of spring can be divided into chemical corrosion and electrochemical corrosion according to the type of reaction.They are the result of changes in the metal atoms on the surface of the spring or the loss of electrons to an ionic state.If the metal on the surface of the spring simply reacts with the surrounding medium, and the spring causes corrosion, it is called chemical corrosion.For example, the spring is oxidized in the particularly dry atmosphere to form an oxidation film, and the spring is chemically changed with the liquid or impurity in the non-electrolyte liquid, which is a chemical corrosion.If the spring is in contact with the electrolyte solution, the corrosion caused by the action of the micro battery is called electrochemical corrosion.For example, the spring is...

Spring is a kind of elastic element widely used in the mechanical and electronic industries. Spring can produce greater elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state, and the deformation energy is transformed into mechanical work or kinetic energy.The ratio of load and deformation of the spring is called spring stiffness.  There are many kinds of springs. They are used in various fields. According to the deformation condition, they can be divide...

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.Linear springsLinear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and i...

1、What is Passivation?As a post-fabrication method, passivation is intended to maximize the natural corrosion resistance of stainless steel. Stainless steel is a steel alloy that contains a minimum of 10.5% chromium content by mass and along with a number of other alloys. When stainless steel is newly formed it needs to be cleaned of lubricants, oils, greases and other substances used in its fabrication. Once the steel has been cleaned it must be passivated. Passivation is a process that treats metal surfaces with an acid solution to make the surface corrosion resistant.Passive to atmospheric ...

The inner diameter of the spring should be kept to a certain gap, and the friction force and friction torque caused by the contraction of the inner diameter of the spring should be avoided, and the measurement accuracy should be affected. But the spindle can not be too small, otherwise it will cause the offset between the external torque and the measuring torque center, resulting in the error of the torque measurement.

At first, during the experiment, Hooke found that the weight added to the spring was proportional to the elongation of the spring, and he tested his conjectures by many experiments. In 1678, Hooke wrote a spring paper, which introduced the results of experiments on elastic objects, laying the foundation for the development of material mechanics and elastic mechanics.Spring dynamometerIn the early nineteenth Century, under the premise of a lot of experimental work in the former, British scientist Thomas Yang summed up the research results of Hooke and others, pointing out that if the elongation of the elastomer exceeds a certain limit, the material will break, and the law of elastic force is no longer applicable, and clearly points out the scope of application of the law of elastic force.

Springs can also be classified by how they’re made. The first spring that comes to most people’s minds is probably a metal coil spring, also known as a helical spring. However, there are many other types. Even an elastic band can be considered a variable rate spring, since it stores mechanical energy. Coil SpringsLightweight coil springs are made by forming metal wires on an CNC coiling machine. The multi-axis CNC control allows you to create variable pitches and end conditions only limited by your imagination. Springs that come off the coiling machines do not have springy properties. They need to be heated to a high temperature (typically 500 degrees Fahrenheit or more) to relieve stress, then quenched to create shape memory.In contrast, when making heavy duty coil springs, the wire is he...

The spring is often subjected to variable load or impact load. In order to ensure that the spring can work permanently and reliably, the material must have high elastic limit and fatigue limit. At the same time, it should have enough toughness and plasticity and good heat treatment.Spring materials and properties can be consulted in relevant manuals, specifications and standards (GB/T129.6-92, GB4357-89). The common spring steel is mainly:1: carbon spring steelThis kind of spring (such as 65, 70 steel, etc.) has the advantages of cheap price, convenient source of raw materials, low elastic limit, easy to lose elasticity after repeated deformation, and can not work at 130 degrees.2: low manganese spring steelCompared with carbon spring steel, the spring steel, such as 65Mn, has the advantag...

Springs are ubiquitous in all kinds of machines—from consumer products to heavy industrial equipment, take apart anything that involves a mechanism, and chances are, you’ll find a spring inside. Springs are storage devices for mechanical energy—think of them as analogous to batteries! The earliest spring-driven clocks appeared in the 1400s. Fast-forward some 600 years, you still have to charge the Apple Watch everyday, and it’s not nearly as fast as winding a clock…but I digress.My personal fascination with springs began with Slinkies and wind-up toys, and countless mechanical pencils were sacrificed to satisfy my curiosity. These days, I appreciate the grown-up applications of springs, especially when I drive over potholes on Highway!

Spring is no stranger to everyone. This element is seen everywhere in life. It is also one of the important parts of many industrial machinery equipment. There are many kinds, with different forms, specifications and sizes, and are widely used in the field. Now the spring plant is basically able to produce a variety of different springs. This component is made with special steel. The structure is relatively simple, but it is also required for the production process, so the manufacturer's production equipment and technology will affect the finished product.So if you need to choose a better brand or manufacturer to buy, because it is difficult to judge the quality of the quality of the product, it needs to be used to reflect, but to wait for the problem in the solution is more troublesom...
