Description
Technical field
The utility model relates to pump technology field, relates to New type water pump connecting tube further.
Background technique
China is due to drought and water shortage, and rural area, especially northern country still continues to use well-digging underground water intake.And submersible pump is can't do without in water intaking.Original submersible pump connection water pipe adopts iron pipe usually, and its weight is large, perishable, cost is high, not easily install.So novel plastic water pipe progressively substitutes iron pipe.
Existing plastic water pipe, in order to ensure intensity, is provided with some stiffening ribs (triangle as shown in Figure 1, in Fig. 1: base 1, stiffening rib 2, fixed hole 3, sleeve pipe 4, plastic tube 5) usually between base and sleeve pipe.The shortcoming done like this is, adds materials cost; The existence of stiffening rib have impact on operation when tube and tube docking uses screw (usually having 8 screws) fixing, have impact on efficiency.In addition, also have in order to ensure intensity, sleeve pipe arranges muscle hoop, which increases materials cost.General plastic water pipe also adopts individual layer to arrange usually, and after the sun tans by the sun or when unbalance stress is stacked in transport, yielding generation bends.
Model utility content
The purpose of this utility model is just to provide a kind of New type water pump connecting tube, and its life-span is long, good seal, installs safe and convenient, not easily bending deflection.
The purpose of this utility model is achieved through the following technical solutions:
New type water pump connecting tube, comprises the flange plate at plastic tube and plastic tube two ends, and the sleeve pipe of flange plate is placed on plastic tube, sleeve end fixed base, the two ends of plastic tube are respectively arranged with monoyin and monoyang two bases, on the interface of monoyin and monoyang base, adopt annular groove and convex ridge fitted seal respectively; The cloudy base of one plastic tube is fixedly connected with by screw by fixed hole with the positive base of another plastic tube; Described base is provided with solid cable hole, for station pump cable; Described fixed hole is 6; It is characterized in that: base and the sleeve pipe of flange plate are structure as a whole, and adopt cambered surface transition between base and sleeve pipe.
Further:
The radius of curvature R of described cambered surface is less than 1/3rd of outer length L.
The some grooves of described plastic tube two ends outer installment, when base adopts injection moulding method for filling to make, this groove is injection molding and fills up, thus plays effect base and plastic tube tightened up.
Described plastic tube has three layers; Wherein, mesosphere is muscle material, and layer materials is identical.Mesosphere is muscle material, adopts polypropylene material; Layer materials is identical, is high-density polyethylene material and hindered phenol antioxygen 1010 mixing layer.
Described annular groove or convex ridge are inside and outside twice.
Described solid cable hole is circular or oval.
The beneficial effects of the utility model are: 1, adopt cambered surface transition and proof strength between base and sleeve pipe, do not affect installation again; Avoid the operation affecting thread due to the existence of stiffening rib in prior art.2, scientific offering fixed hole.6 fixed holes, annular groove or convex ridges are adopted to be inside and outside twice, after tested, tighten up intensity and meet the requirements completely with sealing, but compare 8 fixed holes, annular groove or convex ridges for inside and outside three roads, decrease the manufacturing cost of grinding tool, decrease operation link during installation simultaneously.3, described plastic tube has three layers, when guaranteeing intensity and working life, effectively can avoid after the sun tans by the sun or when unbalance stress is stacked in transport, producing bending.
In order to make those skilled in the art person understand the utility model scheme better, and enable above-mentioned purpose of the present utility model, feature and advantage become apparent more, below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is prior art structural representation, and Fig. 2 is the utility model structural representation, and Fig. 3 is that the A of Fig. 2 is to structural representation.
In Fig. 2 Fig. 3: base 1, cambered surface 2, fixed hole 3, sleeve pipe 4, plastic tube 5, solid cable hole 6, annular groove 7.
Embodiment
As shown in Figure 2,3, New type water pump connecting tube, comprise the flange plate at plastic tube 5 and plastic tube 5 two ends, flange plate comprises sleeve pipe 4 and is fixed on the base 1 of sleeve end, sleeve pipe 4 is placed on plastic tube 5, the two ends of one section of plastic tube 5 are respectively arranged with monoyin and monoyang two bases 1, on the interface of monoyin and monoyang base 1, adopt annular groove 7 and convex ridge fitted seal respectively; The cloudy base 1 of one plastic tube 5 is fixedly connected with by screw by fixed hole 3 with the positive base 1 of another plastic tube; After docking, the convex ridge of positive base is placed in cloudy base annular groove 7, and mutually coincide; Described base 1 is provided with solid cable hole 6, for station pump cable; Described fixed hole 3 is 6; Described annular groove 7 or convex ridge are inside and outside twice; Base 1 and sleeve pipe 4 are structure as a whole, and adopt cambered surface 2 transition between base 1 and sleeve pipe 4.
The radius of curvature R of described cambered surface is less than 1/3rd of outer length L.
Described annular groove 7 or convex ridge are inside and outside twice.
Be flat bottom described annular groove; Or circular arc bottom.To play sealing effect further.
Described solid cable hole 6 is circular or oval, and its outward edge is thinner, for being directly pressed into cable, and by solid cable hole attached cable.
Described plastic tube two ends arrange groove, and flange plate adopts high-density polyethylene material injection moulding manufacture, and when flange plate adopts injection moulding process to make, this groove is injection molding and fills up, thus plays fixation.The diameter of described groove is 10-14 millimeter, and the degree of depth is 5-6 millimeter (general plastic tube wall thickness is 7-8 millimeter).Described groove can have 8-12.The present embodiment groove is 12.
