Disc Springs for Valves, also be known as Belleville Springs for Valves, Belleville Washers for Valves ... Disc springs are widely used in various types of valves such as Ball Valves, Regulating Valves, Globe Valves, Pigging Valves, and Sea Valves. The load of Disc Springs is large with small deflection, they can provide sufficient valve seat sealing force. The role of the Disc Spring inside the valve is to maintain sufficient contact pressure on the joint. Using Hegong Disc Springs Stacks either in series or parallel, obtain the required force and stroke, to meet the needs of each valve. Disc Springs Stacks apply a pressure and absorb the contraction and expansion that may occur due to pressure, temperature, or relaxation. Depending on the working environment, Belleville Springs for Valves can be produced by material such as Inconel750, Inconel718, 17-7PH. These materials have good corrosion resistance and high temperature resistance, can also provide adaptable working loads under harsh conditions and high temperature environments. Disc springs are the key part to fix Ball Valve, its performance will directly affect the sealing effect of the valve. When we design and manufacture Disc Springs for Ball Valves, we should pay attention to the following points.

Disc Springs for Ball Bearing, also be known as “Bearing Preload Disc Springs”, they are assembled with the radial ball bearings, act as a compensator of thermal expansions during their working. Using Disc Springs to preload radial ball bearings, helps to maintain positioning accuracy, eliminate shaft end play, and minimize vibration and shaft deflection by distributing the load evenly around the bearing race, extends the bearing life, eliminate excessive running noise. In most cases, the outer race of the ball bearing is preloaded with the Disc Spring, and in some cases it is desirable to preload the inner race of ball bearing.  The recommended load value is achieved when the disc spring is deflected to 75% of the initial cone heights (ho). The proper designed ho/t ratio makes a load of disc spring remains nearly constant for a large deflection range.  Disc springs for valves are designed to operate within 20%-80% of their total deflection. Misuse can result in overload, bigger error, or premature fatigue failure. If your working environment requires disc springs to work outside this range, HEGONG SPRING ® engineers can provide guidance or recommend other solutions.

Disc spring can be used in a single piece, as well in multi pieces with different combinations. disc springs stack set is usual to use disc spring stacks with various combinations to meet your specified applications. Description The required various load/deflection characteristics of Belleville disc springs China can be obtained from the various stacking combinations. The stack combination methods and load&deflection relation as the table below. The designed & expected load/deflection characteristics of disc springs stack just be reached under the correct installation. A guiding element is necessary to keep the Hegong disc springs stack in position. This should preferably be a mandrel. HEGONG SPRING® can deliver disc springs stack pre- assembled on a guiding element and highly recommend this way. Advantages of wholesale disc springs stack: 1. Provide specific load/deflection data for the whole set of disc springs stack. (HEGONG SPRING®’s load testing machines can measure loads up to 4000KN) 2. Small load tolerance 3. Easier to install

Belleville Disc Springs also was called "Disc Springs" "Conical Disc Springs", include disc spring stacks, Corrosion Resistant Disc Springs, High Temperature / Cryogenic Disc Springs, Disc Springs for Ball Bearing, Disc Springs for Valves. Disc Springs are widely used in petrochemical, electric power, metallurgy, engineering, machine tools, national defense, and other industries. Bearing Preload Disc Springs manufacturer Description The Disc Spring concept was first invented by a Frenchman Louis Belleville in 1865. So, disc spring is commonly known as Belleville Springs. And sometimes it also was called "Conical disc springs" "Belleville Disc Springs" or "Belleville Washers". Hegong Disc Springs are conically washers and have a rectangular cross- section, which is loaded in the axial direction. It has a small volume and large energy storage compared to traditional helical springs and can be used as a single disc spring or in the stack (stack in parallel, in series or parallel & series combination). The standards for disc springs mainly include DIN2092 (Calculation) / DIN2093 ( Quality Specifications-Dimensions ) of Germany, JIS B 2706- Japan, GB/T 1972-2005 of China and ISO 19690 : 2017 ( HEGONG SPRING ® is the drafting team member for international standard ISO 19690 : 2017 and Chinese national standard GB/T 1972-2005 ).
