A flange, also known as a flange collar or flange; the flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flanges are used in pairs, the low-pressure pipeline can be screwed with the flanges, and the flanges are welded under the pressure of more than four kilograms.
The existing flange still has some shortcomings in the using process, and when in use:
1. the time of a user is delayed due to the connection problem of the flange plate in the use process of the existing flange, and unnecessary troubles are caused to the work of the user when the flange plate is connected in some narrow places.
2. When the existing flange is used, the flange pad at the connecting position is easy to drop, so that inconvenience is brought to installation of a user, and the flange is extremely inconvenient to connect when the flange is used in a narrow space.
3. The existing flange causes inconvenience for connection due to the caliber of a flange interface in the using process, even causes a gap at the connection position and leakage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a location effect is good, the installation precision is high, and is convenient for observe the flange of the convenient to install of the seepage condition.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a flange convenient to installation, includes the flange body, four radial holes have evenly been seted up at the edge of flange body, radial downthehole side is the cambered surface, and the outside is the opening, the axial through-hole of installation pipeline is seted up at the middle part of flange body, still be equipped with the fixed orifices around the flange body, the fixed orifices is totally four and the equidistance is according to annular array distribution, still install the signal hole on the flange body, the signal hole is the through-hole, the bolt hole has still been seted up on the flange body, the bolt hole is located the edge of axial through-hole, and the upper end in bolt hole links to each other with the axial through-hole, the lower extreme in bolt hole communicates with each other with.
Furthermore, the flange bodies are used in pairs, each flange body comprises a first flange body and a second flange body, positioning protrusions are symmetrically arranged on one side of each first flange body, positioning grooves are symmetrically arranged on one side of each second flange body, and the positioning protrusions and the positioning grooves are matched for use.
Furthermore, a sight glass hole for installing a sight glass is further formed in the flange body, and the sight glass hole is a blind hole.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an edge at the flange body opens four radial holes, and radial hole inboard is the cambered surface, and the outside is the opening, therefore two flanges are easy to the hole, and the installation is convenient high; meanwhile, the positioning protrusions and the positioning grooves are arranged on the first flange body and the second flange body respectively, so that positioning is realized, and the mounting accuracy is effectively improved.
