Description

Valve well pre-opening pipe orifice core supplementing structure

Technical Field

The utility model relates to a valve well field specifically is a valve well is opened mouth of pipe in advance and is mended core structure.

Background

The valve well is a prefabricated well body for protecting the valve in the process of laying the water pipe, and the valve well is consistent with the valve well and is prefabricated by utilizing a hot-press forming process. Two pipe holes are needed to be formed at the bottom of the valve well, the pipe holes are used as openings through which the pipelines penetrate, and the pipelines are connected with the valves in the valve well. However, in different pipe laying, the diameters of the pipes are different according to the water supply amount, and in order to ensure the sealing requirements of the pipes and the valve wells, the valve wells with different specifications need to be processed to meet the installation requirements of different pipes in the prefabrication of the valve wells. This just leads to the specification of valve well more, and required mould is more, is unfavorable for production storage, has improved manufacturing cost and storage cost.

SUMMERY OF THE UTILITY MODEL

For solving the not enough of prior art, the utility model provides a valve well is opened mouth of pipe in advance and is mended core structure, its very big reduction the specification quantity of valve well, reduced manufacturing cost and storage cost.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides a valve well preforging mouth of pipe mends core structure, includes valve well main part and base, valve well main part passes through flange joint with the base, valve well main part bottom sets up the upper shed, the base top sets up the lower shed, the upper shed combines to be the mouth of pipe with the lower shed, the nested core of mending in the mouth of pipe, set up the trompil on the mend core.

The upper opening and the lower opening are both provided with annular edges, and the annular edges of the upper opening and the lower opening form a circular ring shape.

The middle part of the bushing is provided with a ring groove, and the ring groove is matched with the ring edge.

The valve well main body is formed by connecting a plurality of arc-shaped pieces through flanges.

The arc-shaped sheet is provided with a plurality of arc-shaped bulges in a linear manner.

And the base is provided with a reinforcing rib.

Contrast prior art, the beneficial effects of the utility model are that:

the utility model discloses an opening on valve well main part and the base only has a specification, fills the vacancy through mending the core, mends opening on the core as passing hole of water pipe to can only can realize the piping erection of different specifications through mending the core die sinking. The size of the complementary core is small, and the cost of the die is much lower than that of the valve well, so that the production cost can be saved. Meanwhile, the core is small in size and easy to store, so that the warehousing cost is low.

Detailed Description

The invention is further described with reference to the accompanying drawings and the specific embodiments. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in fig. 1-3, a valve well preforging mouth of pipe mends core structure, including valve well main part 1 and base 2, valve well main part 1 is formed through flange joint by a plurality of arcs 10, and through the fashioned mode of components of a whole that can function independently, makes valve well main part 1's forming die can the miniaturized lightweight to reduce valve well main part 1's the shaping degree of difficulty. The top of the valve well main body 1 is provided with a well mouth which is covered with a well cover when being installed. A plurality of arc-shaped bulges 11 are linearly prefabricated on the arc-shaped sheet 10. The arc-shaped protrusion 11 can increase the strength of the arc-shaped sheet 10, and when the valve well is buried in soil, the strength of the valve well can be improved, and the deformation of the valve well is avoided. The reinforcing ribs 12 are prefabricated on the base 2, and the reinforcing ribs 12 can improve the strength of the base 2, so that the valve well 1 is not easy to deform in use.

Valve well main part 1 passes through flange joint with

base

2, 1 bottom of valve well main part has

upper shed

3, 2 tops of base have under shed 4, when carrying out being connected of valve well main part 1 and base 2, upper shed 3 and under shed 4 butt joint, and upper shed 3 makes up for mouth of pipe 5 with under shed 4. The pipe orifice 5 is internally nested with a patch core 6, and the patch core 6 is provided with an opening 7. Mend core 6 and filled mouth of pipe 5's position, trompil 7 is the mounting hole of water pipe, and after the water pipe passed in trompil 7, mend core 6 and carry out the shutoff to the gap between mouth of pipe 5 and the water pipe to play good sealed effect, avoid the entering of silt insect. The supplement core 6 can also support the valve well to prevent the valve well from deforming.

The core 6 is consistent with the valve well, and is hot-pressed in a mould by adopting SMC material. The sizes of the outer circles of the bushing cores 6 are consistent, and only the sizes of the openings 7 are different according to the diameter of the water pipe. Wherein the different sizes of the openings 7 determine the different specifications of the patch core 6. This device turns into the specification of mending core 6 with the specification of valve well main part 1, the specification of base 2, promptly through the mend core 6 of many specifications of preparation just can satisfy the specification demand to the valve well under the different operational environment to reduce the production degree of difficulty of valve well, reduced manufacturing cost, reduced many specifications valve well simultaneously because the space that the deposit caused occupies, reduce the storage cost.

The upper opening 3 and the lower opening 4 are provided with an annular edge 8 which is integrally formed, and the upper opening 3 and the annular edge 8 of the lower opening 4 form a circular ring shape. The outer edge of the annular edge 8 is neat, and the annular edge is used for positioning the installation of the bushing 6. The middle part of the bushing 6 is provided with a ring groove 9, and the ring groove 9 is matched with the ring edge 8. The bushing 6 can be stably positioned and installed by the matching installation of the bushing 6 at the annular edge 8. Meanwhile, the arrangement of the ring groove 9 enables the two ends of the bushing 6 to form ring sleeves, and the ring sleeves are matched with the ring edges 8, so that the sealing effect between the bushing 6 and the pipe orifice 5 is better.
