Joint metal hose
Stainless steel metal hose joint effects first was the net sleeve are connected into integration, and the corrugated pipe, joint is also a metal hydraulic hose assembly and metal hose or other fittings, equipment connected components. It ensure that the medium in pipeline system in normal operation. Joint data usually with bellows, net sets of data, multiple stainless steel based. In order to decrease production cost, some of the larger diameter metal hydraulic hose fitting in the delivery of corrosion is not strong or non corrosive medium, joint can be used for carbon steel manufacturing; joint metal hose on the corrosive medium task conditions, corresponding measures if the description is adopted, and the medium to avoid the touch, can also choose carbon steel to manufacture. The layout mode of joint generally divided into spiral, flange type and fast type three categories:
1, screw type: diameter 50 mm below the joint metal hose, high pressure in an operation under the condition of multi thread based on, when tightening the threaded in the future, close cooperation of two joints on the inner and outer taper surface, complete seal. The cone angle is usually 60 degrees, 74 degrees is also useful. The layout, good sealing, but the device when necessary ensure the concentricity of the two docking part. In order to deal with engineering practice is often seen repeated disassembly and assembly and not easy to be concentric and other issues, will also be described as conical and ball head joint cooperation.
2, the flange disc: diameter for the joint metal hose is more than 25 mm, often in an operation under pressure, with flanged mainly, which cooperate to mortise way seal. Along the radial change, also capable of sliding along the axial direction of the looper flange connection of two bodies in the fastening bolt tension effect. The layout of the sealing function is good, but the processing difficulty, simple sealing surface bumps. Special occasions quick release in need, can cut the fastening bolt through hole, made quick detachable flange.
3, express: diameter for the joints of various metal hose 100 mm below the condition of using requirements, in rapid loading and unloading, usually choose fast type. O shaped it commonly used fluorine plastic or special rubber seal ring seal. When the handle to move the view must be in the future, the equivalent of multiple threads of fingers locked; the O shaped sealing ring is pressed more tightly, the sealing function is better. The layout in the fire, war and other necessary for fast loading and unloading is most suitable for the occasion. In seconds, not to be matched with any special tools, can butt or open a group of joint.

How to buy and use metal hose
Metal hydraulic hose manufacturers occupied in modern industry's position was certain. However, if the selection is not correct, the use of unreasonable or not installed properly, could not get ideal effect, even caused serious economic losses. Therefore, the engineering design personnel, operation and repair personnel, all kinds of metal hose connector on the proper use of knowledge must have a basic understanding of.
The selection of the length of
"Hose, can be short or long". However, metal hose working conditions often due to determine the length of inappropriate, caused by this or that problem. For example: metal hose compensator used for too long, will produce the instability; the pump inlet, pump outlet used metal hose is too long, will produce the additional vibration; metal hose is too long for the pipeline system, will produce large fluid resistance etc.. Of course, put them to shorten the length of some, there can avoid these problems. However, blindly shorten. It is impossible to achieve compensation, vibration, noise elimination purposes. At the same time, the superiority of the metal hose in other aspects are not fully reflect. So, to determine the metal hose length is a very important work.
(1) as a metal hose compensator for, its length depends on the diameter size. The following basic principles: the calculation of diameter less than or equal to 250 mm, diameter less than or equal to 400 mm in diameter, that is less than or equal to 1000 mm,: in the pipeline system, if the compensation of a compensator is not enough, you can use two, three....... If by spatial location conditions, compensator may not install a plurality of, can choose a duplex structure. But the formula (7. (7, 1). (7, 2). 3) principle shall not violate.
(2) for the vibration, the elimination of the pump inlet, pump outlet pipe with noise, depends on the length of the path size, i.e. diameter less than or equal to 100 mm, formula (7. 1) ~ (7. 4), the L compensator or metallic flexible hose length; for the compensator or metal hose diameter.
(3) metal hose angular displacement, length depends on the actual bending radius and displacement angle. That is, (4) metal hose of lateral displacement, length depends on the actual bending and transverse displacement radius size. That is: cut the line refers to the time of the lateral displacement of the metal hose, transitional stage two of the same radius, different direction bending pipe. The calculation, according to the times of the diameter generally consider the length of.
(5) in the bending state, parallel longitudinal movement of the metal hose length depends on the actual bending radius and longitudinal movement quantity. That (6) in the bending state, the parallel sections of lateral movement of the metal hose length depends on the actual bending radius and the transverse moving volume size). That is the formula (7. 5) ~ (7. 2), and L is a metal hose flexible segment length; for metal hose diameter; displacement angle; Y is a single horizontal displacement; T is the total displacement of longitudinal or transverse quantity.
