Abstract
The utility model belongs to the field of building drainage accessories in the building industry, and particularly relates to a spiral noise-reduction expansion joint, which includes an expansion joint main body (1), as well as a first bell mouth (11) and a second bell mouth (12) arranged at two ends of the expansion joint main body (1), wherein a plurality of spiral blades (13) are arranged at intervals in the expansion joint main body (1). The plurality of spiral blades are arranged in the expansion joint main body and are evenly distributed according to a certain reasonable angle, so that the appearance is attractive and the water flow impact force is reduced; and the service life of pipe fittings and pipes is improved while the noise reduction function is played. The bell mouths for connection are arranged on the end surfaces of the connecting pipe fitting, and a structure that a seal ring and a gasket are sealed is arranged, so that the seal performance is ensured and meanwhile the installation construction is more convenient and rapid, the construction time is reduced, and the costs for construction and use are lowered.
Description
Technical field
The utility model belongs to the building water drain accessory field of construction industry, relates in particular to a kind of spiral noise reduction slip joint.
Background technique
At present, the domestic noise reduction slip joint that is used for draining, the slip joint main body mainly adopts an end socket joint to connect at two female ends that connect tubing or pipe fitting, and the other end then adopts the mode of the conventional bonding socket joint of draining glue of tradition.The noise reduction slip joint that existing draining is used is not only installed to construction and has been brought inconvenience, and in use noise is bigger, and current are very big to the impact force of tubing and pipe fitting, and the working life of pipe fitting and tubing is short; On sealability, also there is simultaneously certain defective.
The model utility content
The utility model provides a kind of sealability strong and can improve the spiral noise reduction slip joint in the working life of pipe fitting and tubing at above-mentioned the deficiencies in the prior art, simultaneously this slip joint beautiful shape, simple in structure, install convenient.
To achieve these goals, the technical solution of the utility model is:
The utility model kind spiral noise reduction slip joint comprises slip joint main body and first bellmouth and second bellmouth of being located at described slip joint main body two ends, is arranged at intervals with the multi-disc helical blade in the described slip joint main body.
Described helical blade distributes with homogeneous angular.
Described helical blade is three.Helical blade is distributed on pipe fitting inner wall by certain reasonable angle, guides current to greatest extent, reduces water flow pressure and impact force, plays the effect of unhurried current noise reduction.
Described second bellmouth is equipped with seal ring, packing ring and lid from the inside to surface successively, utilizes the direct socket joint of seal ring and packing ring to be connected when connecting tubing, and is easy to assembly.
Described slip joint main body middle part is provided with the inspection socket that is used to check pipeline.Described inspection socket is equipped with seal ring and nut from the inside to surface successively.
The utility model with respect to the beneficial effect of prior art is:
The utility model is provided with the multi-disc helical blade and by uniform not only beautiful shape of certain reasonable angle and reduction water flow impact pressure, is playing sound-deadening and noise-reducing on, the working life of also having improved pipe fitting and tubing simultaneously in the slip joint body interior.End face at connection pipe fitting is provided with the bellmouth connection, and the structure of seal ring and washer sealing is set, and also makes installation more convenient when guaranteeing sealability, has improved the engineering time, has reduced construction and user cost.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model spiral noise reduction slip joint.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, spiral noise reduction slip joint comprises slip joint main body 1 and is located at first bellmouth 11 and second bellmouth 12 at described slip joint main body 1 two ends, the 11 direct and tubing bayonet joints of first bellmouth, second bellmouth 12 is equipped with seal ring 4, packing ring 5 from the inside to surface successively and covers 6, utilize seal ring 4 to be connected when connecting tubing with packing ring 5 direct socket joints, when guaranteeing sealability, also make installation more convenient, improved the engineering time, reduced construction and user cost.
Slip joint main body 1 inwall by angle with rational uniform be provided with three helical blades 13, not only beautiful shape and reduce water flow impact pressure is playing sound-deadening and noise-reducing on, the working life of also having improved pipe fitting and tubing simultaneously.
Slip joint main body 1 middle part is provided with the inspection socket 2 that is used to check pipeline, and inspection socket 2 is equipped with seal ring 21 and nut 22 from the inside to surface successively.Be provided with inspection socket, be convenient to pipe inspection.
Claims (6)
