Description

Built-in insert of plastic gate valve

Technical Field

The utility model relates to a plastic gate valve field especially relates to a plastic gate valve embeds inserts.

Background

Due to the advantages of light weight, corrosion resistance, no scale adsorption, integral connection with plastic pipelines, long service life and low cost, the plastic valve has the advantages of incomparable application in pipeline systems of water supply (especially hot water and heating) and other industrial fluids.

However, the plastic valve needs to be connected with the metal pipe through threads, and because the hardness and rigidity of the metal pipe are much stronger than those of the plastic valve, if the plastic valve is directly screwed with the metal pipe, the internal threads of the plastic valve are damaged, and the sealing effect cannot be achieved. Therefore, a method for learning a plastic joint is needed to embed an insert in an interface of a plastic valve, and the insert is screwed with a metal pipe by using internal threads arranged in the insert, but how to firmly combine the insert with the plastic gate valve is a problem to be solved in the field.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above problem that prior art exists, provide a plastic gate valve embeds inserts.

For realizing above-mentioned technical purpose, reach above-mentioned technological effect, the utility model discloses a following technical scheme realizes:

the utility model provides a plastic gate valve embeds inserts, is including the annular inserts body that has the internal thread, the outside of inserts body is provided with the annular first flange of many circles outside outstanding, every circle set up a plurality of first through-hole that link up from top to bottom on the first flange.

Furthermore, a downward bent flanging is arranged on the outer side of the top end of the insert body, and a first annular accommodating groove is formed in the bottom end of the flanging.

Furthermore, the bottom end inner side of the insert body is provided with a limiting portion protruding inwards, the bottom end inner side of the limiting portion is provided with an extending portion extending downwards, and the bottom end of the extending portion is provided with a second annular accommodating groove.

Furthermore, a circle of annular second flange protruding outwards is arranged on the outer side of the extending portion, and a plurality of second through holes penetrating up and down are formed in the second flange.

Furthermore, a chamfer is arranged on the inner side of the top end of the insert body.

The utility model has the advantages that: set up many rings of first flanges in the outside of inserts body, set up the first through-hole that link up from top to bottom of a plurality of on first flange for plastic gate valve is when production, and it has plastics to fill in the first through-hole, thereby makes the plastics of first flange both sides form a whole, has increased the fastness that inserts and plastic gate valve combined.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the invention without undue limitation to the invention. In the drawings:

fig. 1 is a schematic structural view of an insert in an embodiment of the present invention;

fig. 2 is a schematic structural view of the embodiment of the present invention, wherein the insert is combined with the plastic gate valve.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

In the description of the present invention, it is to be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", and the like, indicate positional or positional relationships, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the plastic gate valve built-in insert comprises a circular insert body 1 with internal threads 2, wherein four circles of circular first flanges 3 protruding outwards are arranged on the outer side of the insert body 1, a plurality of first through holes 4 penetrating up and down are formed in each circle of first flange 3, and the first through holes 4 in the same first flange 3 are arranged in an annular array.

Set up many rings of first flange 3 in the outside of inserts body 1, set up a plurality of first through-hole 4 that link up from top to bottom on first flange 3 for plastic gate valve 13 is when production, and it has plastics to fill in first through-hole 4, thereby makes the plastics of first flange 3 both sides form a whole, has increased the fastness that inserts body 1 and plastic gate valve 13 combined.

The top outside of inserts body 1 is provided with downwarping turn-ups 5 to the annular first holding tank 6 of a circle is seted up to the bottom of turn-ups 5. The turn-ups 5 forms the parcel structure to the tip of plastic gate valve 13, prevents the tip and the separation of inserts body 1 of plastic gate valve 13, and the setting of first holding tank 6 further increases the fastness of combining between turn-ups 5 and the plastic gate valve 13.

The bottom inboard of inserts body 1 is provided with spacing portion 7 of inside salient, and the bottom inboard of spacing portion 7 is provided with downwardly extending's extension 8, and annular second holding tank 9 of a circle is seted up to the bottom of extension 8.

Spacing portion 7 plays the length of injecing tubular metal resonator and plastic gate valve 13 looks spiro union when tubular metal resonator and plastic gate valve 13 spiro union, and extension 8 is favorable to the inner wall smooth connection of inserts body 1 and plastic gate valve 13, and the setting of second holding tank 9 further increases the fastness that combines between extension 8 and the plastic gate valve 13.

A circle of annular second flange 10 protruding outwards is arranged on the outer side of the extending part 8, and a plurality of second through holes 11 penetrating up and down are formed in the second flange 10. Set up round second flange 10 in the outside of extension 8, set up the first and through-hole 11 that link up from top to bottom of a plurality of on second flange 10 for plastic gate valve is when production, and it has plastics to fill in the second through-hole 11, thereby makes the plastics of second flange 10 both sides form a whole, has increased the fastness that inserts body 1 and plastic gate valve 13 combined.

The inner side of the top end of the insert body 1 is provided with a chamfer 12. The chamfer 12 facilitates the butt joint of the end of the metal tube with the internal thread 2 in the insert body 1.

In the description herein, references to the description of "one embodiment," "an example," "a specific example," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
