Abstract

The utility model discloses a connecting pipe fitting which comprises a connecting pipe fitting body. Grooves are arranged at pipe mouths of two end faces of the connecting pipe fitting body, and are 1-2.8 millimeters deep and 1-3.2 millimeters wide. According to the connecting pipe fitting, the groove structures at two ends of the connecting pipe fitting body are combined with a layer of plastic injected on the inner wall of the connecting pipe fitting body so that not only is connection of two or a plurality of water supply pipelines achieved, but also pollution caused by direct contact of tap water and the pipe wall is better avoided.

Description

Connection pipe fitting

Technical field

The utility model relates to the feedwater field, is specifically related to a kind of connection pipe fitting.

Background technique

In the aqueduct in feedwater field, the link of moulding water pipe for two linings of connection is generally spheroidal graphite cast iron groove pipe fitting, if the inwall of this spheroidal graphite cast iron groove pipe fitting directly contacts with water, heavy metal or other material in the spheroidal graphite cast iron groove pipe fitting can enter in the tap water, thereby pollution tap water, affect people to the use of tap water, in order to prevent the generation of problem, the inwall of spheroidal graphite cast iron groove pipe fitting of being everlasting in the prior art is coated for the powder of isolation etc., but effect is unsatisfactory, can not reach drinking water standard.

The model utility content

The utility model has overcome the deficiencies in the prior art, and a kind of connection pipe fitting is provided, and is convenient at pipe fitting inner wall injection moulding one separation layer, to solve the easy contaminated problem of tap water.

Consider the problems referred to above of prior art, according to the disclosed aspect of the utility model, the utility model by the following technical solutions:

A kind of connection pipe fitting comprises the connection pipe fitting body, and the mouth of pipe place of described connection pipe fitting body both ends of the surface all is provided with groove.

In order to realize better the utility model, further technological scheme is:

As preferably, the degree of depth of described groove is 1 millimeter to 2.8 millimeters.

As preferably, the width of described groove is 1 millimeter to 3.2 millimeters.

As preferably, the angle of described groove floor and groove outside one side is that 6 degree are to 35 degree.

As preferably, the height of described groove inboard is 1 millimeter to 3.5 millimeters.

As preferably, the height difference between the described groove outside and the groove inboard is 1 millimeter to 3.5 millimeters.

The utility model can also be:

As preferably, described connection pipe fitting body is spheroidal graphite cast iron groove pipe fitting.

As preferably, described connection pipe fitting be lead directly to, a kind of in the threeway, elbow, flange.

Compared with prior art, one of the beneficial effects of the utility model are:

In the technical solution of the utility model, the groove structure at connection pipe fitting body two ends and the combination of injection moulding one deck plastics on the connection pipe fitting inner body wall, not only can well realize the connection of two/many feedwater pipings, and can better avoid tap water directly to contact with tube wall and the pollution that causes.

Description of drawings

For clearer explanation present specification embodiment or technological scheme of the prior art, the below will do simple the introduction to the accompanying drawing of required use in the description of embodiment or prior art, apparently, the accompanying drawing that the following describes only is the reference to some embodiments in the present specification, for those skilled in the art, in the situation of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 shows the structural representation according to an embodiment's of the utility model connection pipe fitting;

Fig. 2 is the generalized section with reference to A-A shown in Figure 1;

Fig. 3 is the enlarged diagram with reference to B shown in Figure 2 place.

Wherein, the corresponding name of the reference character in the accompanying drawing is called:

1-connection pipe fitting body, the 2-groove, 3-is inboard, the 4-outside.

Embodiment

Below in conjunction with embodiment the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.

Fig. 1 shows the structural representation according to an embodiment's of the utility model connection pipe fitting.Structural representation with reference to a kind of connection pipe fitting shown in Figure 1 comprises connection pipe fitting body 1, and the mouth of pipe place of described connection pipe fitting body 1 both ends of the surface all is provided with groove 2.

Fig. 2 is the generalized section with reference to A-A shown in Figure 1.A side of setting in the present embodiment near connection pipe fitting body 1 inwall is inboard 3, and this side of close connection pipe fitting body 1 outer wall is the outside 4, and the height in the outside 4 refers to that 4 tops, the outside are to the perpendicular distance of groove 2 bottom surfaces.

Fig. 3 is the enlarged diagram with reference to B shown in Figure 2 place.As shown in Figure 3, the degree of depth h of groove 2 is 1 millimeter to 2.8 millimeters, and the degree of depth h here refers to the perpendicular distance of inboard 3 tops and groove 2 bottom surfaces.

Continuation is referring to shown in Figure 3, and the width d of described groove is 1 millimeter to 3.2 millimeters, and the width d here refers to the perpendicular distance between place, the upper edge vertical direction in the inboard 3 of groove 2 and the outside 4.

As shown in Figure 3, the angle a of described groove 2 bottom surfaces and the groove outside 3 one sides is that 6 degree are to 35 degree.

The height of described groove inboard 3 is 1 millimeter to 3.5 millimeters, and inboard 3 height refers to that inboard 3 tops are to the perpendicular distance of groove 2 bottom surfaces.

Height difference b between the described groove outside 4 and the groove inboard 3 is 1 millimeter to 3.5 millimeters.

Described connection pipe fitting body can be spheroidal graphite cast iron groove pipe fitting.The description that inventive point is carried out in the embodiment of this specification and the Figure of description, as some other structure also can be arranged for connection pipe fitting body 1 outer wall.

The connection pipe fitting body 1 that above embodiment describes can be lead directly to, a kind of in the threeway, elbow, flange, certainly this be not make exhaustive, except this can also have other type.

Connection pipe fitting body 1 inwall described above arranges a plastic layer, one end of plastic layer and cooperating of groove 2, so that plastic layer is attached on the inwall of connection pipe fitting body 1 is more firm, prevented that by plastic layer tap water from directly contacting with connection pipe fitting body 1, avoided metal and other contaminating impurity tap water in the connection pipe fitting body 1.

Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and other embodiment's difference that identical similar part cross-references gets final product between each embodiment.

" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", etc., refer to specific features, structure or the characteristics described in conjunction with this embodiment and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiments this feature, structure or characteristics also drop in the scope of the present utility model.
