Abstract
The utility model relates to a pipe joint. The pipe joint is a cylindrical hollow pipe. The diameter of the pipe joint is slightly greater than that of a pipe to be connected; the inner walls of both ends of the pipe joint are respectively provided with a thread section; the inner sides of the thread sections are provided with raised edges projecting to the inside of the pipe; and the thread directions of the thread sections of both ends are opposite. The utility model has the advantages of high tightness and long service life.
Description
Technical field
The utility model relates to the pipeline connection technology field, particularly a kind of pipe joint that is used for water pipe or tracheae connection.
Background technique
Being connected in the engineering construction of pipeline is very important, often needs good pipe joint can guarantee the sealing of pipeline and the intensity of connection in pipeline connects.During existing pipeline connects, because the hand of spiral in the pipe joint is generally identical direction, be forward, so when carrying out the pipeline connection, need at first pipe joint to be connected earlier with the pipe of a side, and then be connected with the pipe of opposite side, assemble cumbersome, and smooth cylndrical surface, position in the pipe joint, the pipe of both sides is by after being threaded of pipe joint, and sealing is not fine on the one hand, the leakage of medium in causing easily managing after long-time the use, particularly water pipe makes helical thread portion get rusty easily, and the connection of pipe can't be unclamped.
Summary of the invention
The purpose of this utility model is that the problem that connects inconvenience and poor sealing at the existing pipe joint described in the background technique when connecting pipe provides a kind of pipe joint.
The realization the technical solution of the utility model is as follows:
A kind of pipe joint, it is cylindric hollow tubular, and its slightly larger in diameter is in the diameter of the pipe that will connect, and inwall is provided with thread section at the two ends of pipe joint, and the thread section inboard is provided with to the inner convex edge of protruding of pipe, and the thread section hand of spiral at two ends is opposite.
For the ease of the connection of pipe, the outer wall of described pipe joint is provided with hex surface.
In order to strengthen sealing effect, position, described convex edge is provided with seal ring.
The beneficial effects of the utility model are because the hand of spiral of the thread section of pipe joint of the present utility model both sides is opposite, so in assembling if with the screw thread of the pipe of both sides and pipe joint to good, rotating pipe joint just can be screwed into the pipe of both sides in the pipe joint, because the thread section inboard of pipe joint is provided with the convex edge, so when connecting the end face of the interface end of pipe is close on the convex edge, the sealing of pipe joint is improved, and can prevent the screw thread over-tightened and thread damage is caused the decline of pipe seal.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
1 is hollow tubular among the figure, and 2 is thread section, and 3 is the convex edge, and 4 is seal ring.
Embodiment
With reference to a kind of pipe joint shown in Figure 1, it is cylindric hollow tubular 1, and its slightly larger in diameter is in the diameter of the pipe that will connect, and inwall is provided with thread section 2 at the two ends of pipe joint, thread section 2 inboards are provided with to the inner convex edge 3 of protruding of pipe, and thread section 2 hand of spirals at two ends are opposite.For the ease of the connection of pipe, the outer wall of described pipe joint is provided with hex surface, can be rotated with the outer wall of instrument gripping tube fitting like this, can very easily pipe and pipe joint be coupled together.For the sealing of reinforced pipe joint, 3 positions, described convex edge are provided with seal ring 4, and after pipe was tightened like this, the pressure between the end face of pipe connecting end and the convex edge 3 can compress seal ring 4, can guarantee that like this seal ring 4 has good sealing effect.The hand of spiral of the thread section 2 of pipe joint both sides is opposite, so in assembling if with the screw thread of the pipe of both sides and pipe joint to good, rotating pipe joint just can be screwed into the pipe of both sides in the pipe joint, because the thread section of pipe joint 2 inboards are provided with convex edge 3, so when connecting the end face of the interface end of pipe is close on the convex edge 3, the sealing of pipe joint is improved, and can prevent the screw thread over-tightened and thread damage is caused the decline of pipe seal.
