Abstract

The utility model relates to a hose capable of eliminating pulsation. The hose comprises a tube body and a quick connector and is characterized in that the tube body is formed by an inner layer and an outer layer, and a plurality of annular reinforced bodies are arranged between the inner layer and the outer layer. The hose can be applied to a conveying pipeline of a piston pump, a hose pump, a diagram pump and the like capable of pumping out materials intermittently. The hose can be connected at any position of the conveying pipeline to eliminate pulsation caused by pumping out materials intermittently to finish accurate gauge and construction spray of conveyed materials.

Description

Eliminate the flexible pipe of pulsation

Technical field

The utility model relates to a kind of flexible pipe, relates in particular to a kind of flexible pipe of eliminating pulsation.

Background technique

Eliminate the interruption pumps such as reciprocating pump, peristaltic pump, diaphragm pump in the past and adopt diaphragm type, air sac type ripple damper to be installed in delivery outlet in the pulsation of carrying that solid content is low, produce during the good fluidity material more, can eliminate 90% pulsation, be enough to satisfy industrial requirements.Progress along with Building technology has proposed Secretary to construction plant, and applying of building industry dry-mixed mortar particularly is badly in need of solving the reliability of Mortar spraying machine novel device mechanized construction technology.The new type mortar spraying machine is to finish interior external wall surface spraying to plaster and ground, the lay bricks conveying of mortar, it is steady that wherein wall surface spraying requires the material flowing pressure, just can finish this task continuously, and the utility model is developed for addressing this problem, and has no before this and carries high solid content, uses this structural pipeline to eliminate the equipment of pulsation without mobile material.In the past diaphragm type, air sac type ripple damper, be used on the good mass transport of solid content lazy flow, good results, but it is high to be used for solid content, viscosity is large, poor fluidity, solidify fast slush and carry, but reason one is the cement rapid solidification in the mortar, material is formed in the damper gateway block, thereby damper was lost efficacy; The 2nd, diaphragm type, air sac type ripple damper are because the reasons in structure reflection lags behind, and because of poor flexibility, effect is bad.

The model utility content

The purpose of this utility model is for the deficiencies in the prior art, and a kind of flexible pipe of eliminating pulsation is provided.Be used in the interruptions such as reciprocating pump, peristaltic pump, diaphragm pump and pump on the conveyance conduit of material, the pulsation that is caused is pumped to eliminate to be interrupted in any position that can be connected to conveyance conduit, with accurate measurement and the construction spraying of finishing conveying material.

The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of flexible pipe of eliminating pulsation, comprise body and rapid pipe joint, and it is characterized in that, described body is made of internal layer and skin, at internal layer and outer middle a plurality of ring-types enhancing bodies that are provided with.

Further, the number that described ring-type strengthens body is more than 3, and the spacing that adjacent two ring-types strengthen body is 1～10cm.

Further, described body internal layer and outer field material are the elasticity macromolecular material.

Further, the material of described ring-type enhancing body is metal or high pressure resistant macromolecular material.

The beneficial effects of the utility model are: the material of body internal layer is the elasticity macromolecular material, has the performance of high elasticity, high abrasion, chemical resistance, anti-certain pressure; The outer field material of body is the elasticity macromolecular material, has high elasticity, high wear resistance.Weather resisteant plays a protective role and ring-type is strengthened the fixation of body internal layer; The material that ring-type strengthens body is metal or high voltage bearing macromolecular material, plays effect and styling and anti-certain pressure of restriction inner tube demi-inflation; Two ends are rapid pipe joint in order to be connected with the far-end pipeline with import; Ring-type strengthens flexible pipe between the body under the internal pressure effect, can radial expansion, play the effect that hig pressure storage material low pressure discharges.

Embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.

To shown in Figure 3, a kind of flexible pipe of eliminating pulsation comprises body 5 and rapid pipe joint 4 such as Fig. 1, it is characterized in that, described body is made of internal layer 2 and outer 1, is provided with a plurality of ring-types and strengthens body 3 in the middle of internal layer 2 and outer 1.

Further, the number that described ring-type strengthens body 3 is more than 3, and the spacing that adjacent two ring-types strengthen body 3 is 1～10cm.

Further, the material of described body internal layer 2 and skin 1 is the elasticity macromolecular material.

Further, the material of described ring-type enhancing body 3 is metal or high voltage bearing macromolecular material.

The material of body internal layer 2 is the elasticity macromolecular material, performance with high elasticity, high abrasion, chemical resistance, anti-certain pressure, according to conveying material to require different-thickness be 0.5～4.0cm begins to expand when pressure 0.5 MPa, working pressure 〉=5.0 MPa rupture pressures are more than 10.0 MPa; The material of body skin 1 is the elasticity macromolecular material, has high elasticity, high wear resistance and plays the protective action of internal layer 2 and ring-type is strengthened the fixation of body 3, and thickness is 0.2～0.3cm; The material that ring-type strengthens body 3 is metal or high pressure resistant macromolecular material, play effect and styling and anti-certain pressure of the demi-inflation of restriction inner tube, different according to pressure and output quantity, generally being designed to spacing is 1～4cm, the ring-type width is 0.5-5cm; Thickness is 0.1-0.5cm, and two ends are rapid pipe joint 4 in order to be connected with the far-end pipeline with import; The flexible pipe that ring-type strengthens between the body 3 can radial expansion, plays the effect that hig pressure storage material low pressure discharges.

Working principle, the rapid pipe joint 4 at two ends and import and far-end pipeline are connected to form a complete conveyance conduit, this structural tube can be installed in the intermediate portion of conveyance conduit as required, usually this type of outlet pressure is 0～1.2 MPa, main equipment is 0～3.0 MPa, radial expansion occurs in body under the effect of gateway pressure, every increase by 0.1 MPa of pressure, outwards expansion 0.1%-0.2% makes pipeline capacity when high pressure increase like this, play the effect of storing material, when pressure drop, rely on the rebound elasticity of pipeline and the binding force of annular enhancing body to keep certain pressure in the tube chamber, and discharge the material of storage, make whole tube chamber form a relatively continuous mode of the relatively stable material stream of pressure, thus the requirement of satisfying spraying and carrying.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
