Abstract
The utility model discloses a sealing ring for connecting polyethylene double-wall corrugated pipe, which comprises 2-5 positioning rings (1) which are clamped on the wave bottom of a double-wall corrugated polyethylene tube, wherein the 2-5 positioning rings (1) are mutually connected, and the upper ends of the positioning rings (2) are provided with water stop rings (2). The sealing ring can increase the contact area between the water stop rings and the double-wall corrugated polyethylene tube, water can not be leaked under the condition that the interface is locally pressed, and the sealing property of the sealing ring is improved. The water stop rings are in helical teeth shape, when jacketing, the double-wall corrugated polyethylene tube is sleeved along the teeth, the connection of a pipeline is easier, when the double-wall corrugated polyethylene tube is drawn, the helical teeth shaped water stop rings can generate bigger resistance for preventing being dropped on the interface, and water stop effects can be improved through adopting the helical teeth shaped water stop rings.
Description
Technical field
The utility model relates to a kind of seal ring, particularly a kind ofly connects the seal ring that polyethylene double-wall corrugated pipe is used.
Background technique
The connection of polyethylene double-wall corrugated pipe now more adopts socket joint to connect.Socket end in not enlarging when connecting puts seal ring, and the socket that the mouth of pipe that will be with seal ring then inserts enlarging gets final product.The positioning ring that existing seal ring is connected with the trough of polyethylene double-wall corrugated pipe mostly is one, cause the mouth of pipe area of contact of seal ring and polyethylene double-wall corrugated pipe less, in use leak easily, it is special when the interface position of polyethylene double-wall corrugated pipe is squeezed, the probability that leaks will further increase, and has restricted the popularization of polyethylene double-wall corrugated pipe.Simultaneously the water-stop ring on the existing seal ring mostly is cylinder type or direct tooth type, and like this, first sealability is bad, second when the polyethylene double-wall corrugated pipe tension, the very easy pull-off of jointing.
Summary of the invention
The purpose of this utility model is, a kind of good seal performance is provided, can prevents the seal ring that the connection polyethylene double-wall corrugated pipe of pull-off is used, and can overcome the deficiencies in the prior art.
The technical solution of the utility model; It comprises the positioning ring that is connected to polyethylene double-wall corrugated pipe trough place, and the quantity of positioning ring is 2～5, and 2～5 positioning rings interconnect; Upper end at positioning ring is provided with water-stop ring.
The quantity of positioning ring is 2～3.
Water-stop ring be shaped as the helical teeth shape.
Compared with the prior art, the utility model adds most 2～5 with the quantity of positioning ring, and 2～5 positioning rings interconnect, and establish water-stop ring in the upper end of positioning ring, so just can strengthen the area of contact of water-stop ring and polyethylene double-wall corrugated pipe, under the situation of interface local compression, can not leak yet, improve the sealing of seal ring.The quantity that positioning ring is generally chosen is 2～5, is preferably 2～3, and these data all are claimants through a large amount of test gained, can guarantee sealing, again too much waste material not; Water-stop ring is shaped as the helical teeth shape, when socket, polyethylene double-wall corrugated pipe is inserted in along tooth, make the connection of pipeline very light, when the polyethylene double-wall corrugated pipe tension, the water-stop ring of helical teeth shape will produce bigger resistance, prevents that jointing from coming off, and adopts the helical teeth water-stop ring can improve stagnant water effect.Simultaneously the utility model also have make simple, service life is long, can increase the advantage of polyethylene double-wall corrugated pipe mouth of pipe hardness.

Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, the head and the tail socket joint that is connected to of polyethylene double-wall corrugated pipe 3 connects, connect for convenient, end at polyethylene double-wall corrugated pipe 3 is provided with bellmouth 4, for guaranteeing the sealing at bell and spigot joint place, tail end at another root double-wall corrugated pipe polyethylene pipe 3 is with seal ring, seal ring is to be connected in the trough of polyethylene double-wall corrugated pipe 3 by positioning ring 1 to position, for increasing the area of contact of seal ring and bellmouth 4, the quantity that positioning ring 1 is selected for use is 2～5, is preferably 2～3, and is to interconnect between several positioning ring 1, for improving sealing effect, be processed with water-stop ring 2 in the upper end of positioning ring 1.With water-stop ring 2 be shaped as the helical teeth shape, can further increase sealing effect like this, can increase the resistance to plucking pulling force of polyethylene double-wall corrugated pipe 3 again.
Claims (3)
1. one kind connects the seal ring that polyethylene double-wall corrugated pipe is used, and it comprises the positioning ring (1) that is connected to polyethylene double-wall corrugated pipe trough place, it is characterized in that: the quantity of positioning ring (1) is 2～5, and 2～5 positioning rings (1) interconnect; Be provided with water-stop ring (2) in the upper end of positioning ring (1).
2. the seal ring that connection polyethylene double-wall corrugated pipe according to claim 1 is used is characterized in that: the quantity of positioning ring (1) is 2～3.
