Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, not do under the situation of opposite explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings like " upper and lower, left and right "; " inside and outside " is meant inside and outside with respect to the profile of each parts itself.
An aspect according to the utility model provides a kind of pipe clamp, wherein; This pipe clamp comprises two pipe clamp portions 1 that can be mutually permanently connected; Each pipe clamp portion 1 has the skin 2 and internal layer 3 that mutual coupling is installed, and said outer 2 are processed by rigid material, and said internal layer 3 is processed by high-abrasive material.
Through using the double-deck pipe clamp of having of the utility model portion 1, can utilize outer 2 to provide enough intensity indeformable, and can utilize internal layer 3 when the vibration that conveyance conduit produces, pipe clamp to be played a protective role to guarantee pipe clamp.
Wherein, for alleviating pipe clamp deadweight, it is outer 2 to use high tenacity material (for example steel, alloyed steel, aluminum alloy, titanium alloy etc.) to make, when enough intensity is provided, to reduce outer 2 weight.Further, can use light wear-resistant material (for example High molecular weight polyethylene, composite polyurethane etc.) to make internal layer 3, when enough wear resistance is provided, to reduce the weight of internal layer 3.
In addition, preferably, said 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 portion 1 like Fig. 4 through 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, as long as can keep its relative position firmly with any suitable mode.For example, can make internal layer 3 be bonded in the inboard of skin 2.In the preferred implementation of the utility model, can make internal layer 3 form dismountable the connection with outer 2, so that when the pipeline butt joint that is used for different size, can only change the internal layer 3 of corresponding specification.
Preferably, the outer surface of said outer 2 internal surface or said internal layer 3 can have clamping convexity 4, and the outer surface of said internal layer 3 or said outer 2 internal surface can have corresponding clamping recess 5, thereby realize dismountable connection through clamping.For example, in mode of execution shown in Figure 7, clamping protruding 4 is formed on the internal surface of skin 2, and clamping recess 5 is formed on the outer surface of internal layer 3.
