Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only is used for description and interpretation the present invention, is not limited to the present invention.
In the present invention, in the situation that do not do opposite explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
According to an aspect of the present invention, provide a kind of pipe clamp, wherein, this pipe clamp comprises two pipe clamp sections 1 that can be mutually permanently connected, each pipe clamp section 1 has skin 2 and the internal layer 3 of mutual Matching installation, and described outer 2 are made by rigid material, and described internal layer 3 is made by high-abrasive material.
The application of the invention have a double-deck pipe clamp section 1, can utilize outer 2 to provide enough intensity indeformable to guarantee pipe clamp, and can utilize internal layer 3 when the vibration that conveyance conduit produces, pipe clamp to be played a protective role.
Wherein, for alleviating pipe clamp deadweight, can use high strength material (such as steel, alloyed steel, aluminum alloy, titanium alloy etc.) to make outer 2, to reduce outer 2 weight when enough intensity is provided.Further, can use light wear-resistant material (such as High molecular weight polyethylene, composite polyurethane etc.) to make internal layer 3, to reduce the weight of internal layer 3 when enough wear resistance is provided.
In addition, preferably, described internal layer 3 has elasticity, thereby when the assembling pipe clamp, internal layer 3 can closely cooperate with the seal ring of pipeline, to strengthen the sealing of pipeline joint.
To shown in Figure 6, can form pipe clamp section 1 as Fig. 4 by internal layer 3 being arranged on outer 2 inboards.Wherein, outer 2 internal surface and the outer surface of internal layer 3 coupling are so that the relative position of skin 2 and internal layer 3 is firmly constant.
Wherein, can make internal layer 3 be arranged on outer 2 inboard in any suitable mode, as long as can keep its relative position firmly.For example, can make internal layer 3 be bonded in outer 2 inboard.In the preferred embodiment of the present invention, can make internal layer 32 form dismountable connection with being connected, so that when the pipeline docking that is used for different size, can only change the internal layer 3 of dimension.
Preferably, the outer surface of described outer 2 internal surface or described internal layer 3 can have clamping projection 4, and the outer surface of described internal layer 3 or described outer 2 internal surface can have corresponding clamping recess 5, thereby realize dismountable connection by clamping.For example, in mode of execution shown in Figure 7, clamping projection 4 is formed on the internal surface of skin 2, and clamping recess 5 is formed on the outer surface of internal layer 3.
More preferably, as shown in Figure 7, described outer 2 and described internal layer 3 comprise separately circumferential wall and be connected in the sidewall of this circumferential wall both sides, described clamping projection 4 and described clamping recess 5 be arranged on described outer 2 and the corresponding sidewall of described internal layer 3 on.The collision that produces in course of conveying due to pipeline junction is outer 2 and the joint of the internal layer 3 Main Function power of bearing, the location in axial direction of its major effect outer 2 and internal layer 3.By the layout of present embodiment, can by be arranged on outer 2 and the sidewall of internal layer 3 on clamping projection 4 and clamping recess 5 location of guaranteeing axial direction.
