6. We can customize disc spring as per customer's requirements.
7. Application: Production facilities, instrumentation industry, control valve manufacturer, power station
8. Disc spring stacks are under hydraulic preload in the open position in quick-action valves. After a failure, the hydraulic pressure drops and releases the spring stack, hence closing the valve. This application mainly uses ball bearing centered stacks. In addition, the spring stack has a self-adjusting function by countering the set-loss of gaskets. This conserves overhead costs as it minimizes required maintenance

Split sets rock bolt is used together with dome plate and net for reliable ground support in mines, tunnels, slopes, or wherever .
1.Features :
(1)split sets bolt is made from high strength steel tube that is a slotted steel tube, with one end tapered tip for easy insertion into a drill hole. The other end has a welded ring for holding the bearing plate. A ring, or collar, is welded on the outer end to hold a domed plate to the rock surface.
(2)the bolt is inserted into a hole slightly , the diameter of hole is smaller than the tube. When drive the rock bolt into the hole, the tube of bolt is compressed and the slot is partially closed , that make the strata and the bolt be a whole body, .All strain of bolt wiill support to the strata tightly. When surrounding rock is shaked by explosion, anchor capacity increasesed higher and supporting effect is perfect.
(3) fast and easy installation with hand held or mechanized equipment .
(4) be used in a variety of ground conditions for immediate ground support, but is not suitable for very soft strata and permanent support.
(5) provide support in radial and axial direction .
2. Recommended hole diameter calculation:
(1) in the rock stratum : a diameter of hole: (0.9-0.95) diameter of bolt
Thread bar bolt is composed of screw thread steel bar , high strength plate , casting damping nut , yield tube, washer , and other accessories . According to the structure of steel bar , the bolt has two stypes : rib rebar bolt and non-rib rebar bolt .
The bolt is usually used in thick coal seam , that has high stress, large deformation, difficult to support and other poor environment .
Feature :
(1) The bolts have high strength stress , good support capacity can prevent the roof from sinking down , and the strata sliding .
(2) Fast and easy installation by mechanized tools.
(3) Be used with resin anchoring cartridge for permanent support .
(4) Be used in high stressed , large deformed area .
(5) Low price, widely used in coal mines, railways, hydropower and other types of roadway projects.
(6)thread profile has higher strength than rod and offers excellent mixing capabilities in resins installation
