Description
Technical field
The present invention relates to pipe joint field, especially a kind of pipe joint structure of preventing water leakage.
Background technique
At present, leak free design when water pipe adapter and water pipe are spirally connected is generally around soft band on water pipe thread face, when being bolted on water pipe to make joint, oppress soft band and embedded squeezing on flank of thread, reach the object of leakproof.This leak-proof manner, when mounted, its tightness is not easily grasped, the technology of the operator that places one's entire reliance upon, therefore, leak preventing effect is not good, when particularly installing water tap, because there is requirement water discharge of water faucet position, when being screwed in by joint to the tightest position, possible water outlet direction is not in optimum position.Now, again must screw out water tap, again curl up soft band, to reach best water exit position.Therefore, leakage proof structure that is time-consuming during installation, effort cannot meet modern construction requirement far away.
Summary of the invention
The object of the invention is, according to above-mentioned the deficiencies in the prior art, to provide a kind of pipe joint structure of preventing water leakage, pad is set by the end in pipe joint, to hold out against the water pipe be connected with pipe joint, avoid both joints to produce the situation of leaking.
The object of the invention realizes being completed by following technological scheme:
A kind of pipe joint structure of preventing water leakage, comprise joint body, described joint body inside is provided with flank of thread, it is characterized in that: bottom described flank of thread, offer a concave ring groove, pad is embedded with in described concave ring groove, the shape of the outer contour shape of described pad, size and described concave ring groove, size are coincide adaptive, form between the two and are tightly connected.
The width of rebate of described concave ring groove is greater than its slot bottom width.
The inwall of described concave ring groove is provided with ladder, and the width of described concave ring groove, from its notch to bottom land direction, diminishes gradually along described ladder.
The width of rebate of described concave ring groove equals its slot bottom width.
The inwall of described concave ring groove is provided with bulbous protrusion.
The One-sided Widths of described pad is 0.13-0.19 times of the internal diameter of described flank of thread.
The height of described pad is 0.02-0.08 times of the internal diameter of described flank of thread.
Advantage of the present invention is: leak resistance is good, easy to install, is suitable for using in Modern Construction, is suitable for making leakage protection device when connecting as all size water pipe and uses; Simple and reasonable, manufacturing is easy; Only by water pipe precession pipe joint, and need can realize preventing water leakage without the need to soft band or other auxiliary items.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the present invention;
Fig. 2 is the second structural representation of the present invention;
Fig. 3 is the third structural representation of the present invention;
Fig. 4 is the 4th kind of structural representation of the present invention.
Embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As Figure 1-4, mark 1-5 in figure to be expressed as: joint body 1, flank of thread 2, concave ring groove 3, ladder 4, bulbous protrusion 5.
Embodiment one: as shown in Figure 1, and the preventing water leakage pipe joint in the present embodiment comprises joint body 1, and joint body 1 is for connecting water pipe.The inwall of joint body 1 is provided with the flank of thread 2 for being connected with water pipe thread.The bottom of flank of thread 2 is provided with concave ring groove 3, and concave ring groove 3 inside is embedded with pad (not shown), and the shape of the outer contour shape of pad, size and concave ring groove 3, size are coincide adaptive, forms between the two and is tightly connected.When water pipe is tightened onto the inside of joint body 1 by screw thread, its end holds out against being inlaid on the pad in concave ring groove 3, the gap now between water pipe and joint body 1 just seal by pad, thus realize the preventing water leakage between water pipe and joint body 1.
As shown in Figure 1, the width of rebate of concave ring groove 3 is greater than its slot bottom width, its role is to water pipe and directly can hold out against pad along the direction of concave ring groove 3, thus improves the waterproof effect between water pipe and joint body 1.
Embodiment two: as shown in Figure 2, the something in common of the present embodiment and embodiment one is, the width of rebate of concave ring groove 3 is greater than its slot bottom width, but be with the difference of embodiment one: on the inwall of concave ring groove 3, be provided with ladder 4, the width of concave ring groove 3, from its notch to bottom land direction, diminishes gradually along ladder 4, and namely the top of ladder 4 is arranged on notch, the bottom of ladder 4 is arranged on bottom land, thus forms the concave ring groove 3 diminished gradually along ladder 4 setting direction width.
Owing to being provided with ladder 4 in concave ring groove 3, after pad is held out against in concave ring groove 3 by water pipe, not easily loosen in concave ring groove 3 or come off, thus improving the waterproof effect between water pipe and joint body 1.
Embodiment three: as shown in Figure 3, and the difference of the present embodiment and embodiment one, two is: the width of rebate of concave ring groove 3 equals slot bottom width, while waterproof effect between guarantee water pipe and joint body 1, improve the efficiency of installing.
Embodiment four: as shown in Figure 4, and the difference of the present embodiment and embodiment three is: on the inwall of concave ring groove 3, be provided with bulbous protrusion 5, and ball bumps 5 is towards the inside of concave ring groove 3.In use, by bulbous protrusion 5, the frictional force between water pipe and joint body 1 can be increased, namely avoid pad loosen from the inside of concave ring groove 3 or deviate from, increase the sealing effect of pad simultaneously further.
Above-described embodiment is in the specific implementation: pad is made by elastic material.Utilize the elasticity of pad, the sealing effect between water pipe and joint body 1 can be strengthened, avoid the situation of leaking between the two.
The shape of pad and concave ring groove 3, size coincide adaptive could form seal, therefore the shape of pad, size determined by concave ring groove 3.If concave ring groove 3 is too shallow, then pad is corresponding too thin, and now the working life of pad is not long; Otherwise concave ring groove 3 is too dark, then pad is corresponding too thick, and now pad is easily out of shape, and easily leaks.Therefore, the height of pad is 0.02-0.08 times of flank of thread 2 internal diameter, and concave ring groove 3 is identical adaptation with pad.If concave ring groove 3 is too wide, then pad is corresponding too wide, and now pad is equally easily out of shape, and easily leaks; Otherwise concave ring groove 3 is too narrow, then pad is corresponding too narrow, and that pad just cannot play sealing effect.Therefore, the One-sided Widths of pad is 0.13-0.19 times of flank of thread 2 internal diameter, and concave ring groove 3 coincide adaptive with the width of pad.
Although above embodiment elaborates the design of the object of the invention and embodiment with reference to accompanying drawing, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the present invention, as: the concrete shape of concave ring groove 3, size; The shape, size etc. of pad, therefore do not repeat one by one at this.
