Referring to fig. 1 to 3, a locker for socket-type and flange-type pipe connection includes a first pipe 11, a connecting pipe 21, and a second pipe 41. In this embodiment, the first pipe 11 is a socket pipe, the second pipe 41 is a flange pipe, the connecting pipe 21 is a ductile iron pipe, and the connecting pipe 21 is used to connect the first pipe 11 and the second pipe 41.
One end of the first pipeline 11 is provided with a socket, one end of the connecting pipeline 21 is provided with a socket 22 inserted into the socket, the sealing end of the socket of the first pipeline 11 is provided with a rubber ring, and the socket of the connecting pipeline 21 is inserted into the socket of the first pipeline 11 by applying force to form a closed pipe capable of adapting to displacement and vibration within a certain range.
Wherein, first pipeline 11 cover is equipped with first flange spare 12, and the connecting tube 21 other end is provided with second ring flange 23, and second ring flange 23 is connected with first flange spare 12 through at least one connecting fastener 31. Preferably, the connecting fasteners 31 are provided in two or more, three in this embodiment, and are circumferentially distributed, and each connecting fastener 31 can be pulled into the distance between the second flange 23 and the first flange 12 to lock the connection between the connecting pipe 21 and the first pipe 11.
In addition, one end of the second pipe 41 is provided with a third flange 42, and the third flange 42 is connected with the second flange 23 through a plurality of second fasteners 32. In this way, the connection pipe 21 is connected at one end to the first pipe 11 and at the other end to the second pipe 41, so that the connection between the socket pipe and the flange pipe is realized, and usually, the socket pipe is a nodular cast iron pipe and the flange pipe is a galvanized steel pipe, that is, the connection pipe 21 enables different pipes of the nodular cast iron pipe and the galvanized steel pipe to be connected. The connecting pipeline 21 locks the socket type first pipeline 11 through each connecting fastener 31, so that the socket joint is firmer and can resist ground subsidence in the later period of use.
Specifically, as shown in fig. 2, the first flange 12 includes a semi-arc-shaped hoop flange 121, two ends of each hoop flange 121 are provided with connecting ear seats 122, and the two corresponding connecting ear seats 122 are connected by a first fastening member 123, so as to tightly fit the first flange 12 on the first pipeline 11, where the first fastening member 123 is a bolt fastening member. And, install in the bell and spigot reducing department of first pipeline 11 at first flange spare 12, when connecting fastener 31 locks, because the bell and spigot reducing department pipe diameter grow of first pipeline 11, first flange spare 12 is difficult to slide after locking. The first flange member 12 not only plays a role of locking the socket of the first pipe 11 but also plays a role of a flange connection port. Moreover, the hoop pipe diameter of the hoop flange plate 121 can be adjusted to adapt to bell sockets with different pipe diameters.
The connecting fastener 31 includes a screw and two fastening nuts screwed on the end of the screw, and the hoop flange 121 and the second flange 23 are both provided with a first through hole 124 for the corresponding screw to pass through. The second fastening member 32 is a bolt fastening member, and the second flange plate 23 and the third flange plate 42 are both provided with a second through hole 231 for the second fastening member 32 to pass through. Furthermore, a third through hole for a corresponding screw to pass through is formed in the third flange plate 42, one end of the screw passes through the second flange plate 23 and the third flange plate 42 in sequence, the fastening nut is pressed against the end face of the third flange plate 42, and the screw is screwed with a connecting nut which is pressed against the end face of the second flange plate 23. Referring to fig. 1 and 3, one end of the screw rod passes through the second flange 23 and the third flange 42, and the fastening nut on the screw rod is pressed against the end surface of the third flange 42, so that the second flange 23 is connected with the first flange 21, and the connecting nut on the screw rod is matched with the fastening nut, so as to connect the second flange 23 with the third flange 42. In this embodiment, 3 connecting fasteners 31 are provided, so that the second flange 23 and the third flange 42 are connected to each other by the second fastener 32. It will be appreciated that the attachment fastener 31 acts on the second flange 23 and the third flange 42 not only to pull the second flange 23 and the first flange member 12 in, but also to attach the second flange 23 and the third flange 42. Therefore, in other embodiments, if the connection between the second flange 23 and the third flange 42 is performed entirely using the connecting fastener 31, it is also understood that the equivalent replacement is possible since the connecting fastener 31 functions as the second fastener 32.
In the operation of this embodiment, first, a force is applied to insert the socket of the connecting pipe 21 into the socket of the first pipe 11; secondly, the second flange 23 of the connecting pipe 21 is connected with the third flange 42 of the second pipe 41 through the second fasteners 32; third, the first flange member 12 mounted on the first pipe 11; fourthly, installing each screw rod, and then locking two ends to fasten nuts.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
