Problems solved by technology

[0004] The purpose of the present invention is to provide a self-sealing pipe joint that can rotate and change the direction of the fluid, so as to solve the problem that the current joints are all non-displaceable, which cannot be realized when there is an emergency or when the installation position is not good and the rotational displacement is required. It is difficult to install, and it cannot be self-sealing, and the liquid will flow out directly after the male and female connectors are disengaged

Embodiment 1

[0027] Example 1, such as figure 1 , Figure 4 to Figure 7As shown, the present invention is a fluid rotatable and azimuth-changing self-sealing pipe joint, including a male joint and a female joint. The male joint includes an inner sleeve 40, and one end of the inner sleeve 40 is connected to a pipe joint 37. The outer circumference of the pipe joint 37 An annular slot 36 is arranged on the top, and a sealing air guide valve core 42 is arranged inside the inner casing one 40 to close the inner port of the pipe joint 37. The inner end of the sealing air guide valve core 42 is provided with a spring six 43, and the female joint includes an inner sleeve 2. The inner cavity of the inner casing 22 is provided with a sealing spool 5 that can slide left and right. One end of the sealing spool 5 is provided with a spring 3. The other end of the sealing spool 5 is fixed with a pressure seal that can be inserted into the male joint. The spool guide rod 16 that air guiding valve core 4...

Embodiment 2

[0036] Example 2, such as figure 2 and image 3 As shown, on the basis of Embodiment 1, a normally closed valve is provided on the transverse pipe 22, and the normally closed valve includes a baffle 25 sleeved on the outer wall of the transverse pipe 22, and a lock ring shell 29 is fixed on the outer left end of the baffle 25, The lock ring housing 29 is provided with a lock ring inner sleeve 28, and the lock ring inner sleeve 28 is provided with a step inner hole, the left end of the step inner hole is closed and opened by the left end of the transverse tube 22, and the outer wall of the transverse tube 22 is provided with a step inner hole. The sliding protruding ring 33 that slides left and right at the right end, the inner wall of the right end of the step inner hole is provided with a steel ball mounting hole three, the steel ball mounting hole three is provided with a steel ball three 34 that limits the sliding protruding ring 33, and the lock ring shell 29 is provided ...

Abstract

The invention relates to a fluid rotatable variable-direction self-sealing pipe joint, and belongs to the technical field of joint sealing. The fluid rotatable variable-direction self-sealing pipe joint comprises an inner sleeve; a sealing valve element capable of sliding left and right is arranged in an inner cavity of the inner sleeve; a spring I is arranged at one end of the sealing valve element, and a valve element guide rod capable of extending into a male joint to press a sealing air guide valve element to open is fixed at the other end of the sealing valve element; a first steel ball installation hole is formed in the inner wall of the right end of the inner sleeve; a first steel ball matched with an annular clamping groove in the male joint is arranged in the steel ball installation hole; and a rotating pipe is rotatably installed at the other end of the inner sleeve. By arranging the first steel ball matched with the annular clamping groove of the pipe joint on the male joint, rapid connection can be performed; in addition, the rotating pipe is arranged, and rotating deflection can be performed without being limited by the installation position; liquid can be drained by rotating the position in an emergency state to avoid from dangerous and expensive devices; and in addition, after the female joint is deviated from the male joint, the sealing valve element performs self-sealing on an inner hole of the inner sleeve under the action of the first spring.

Description

technical field [0001] The invention belongs to the technical field of pipe sealing joints, and in particular relates to a fluid rotatable and azimuth-changing self-sealing pipe joint. Background technique [0002] Traditional pipe quick connectors usually use threaded connections, ferrule connections, etc. However, these methods all have certain problems such as difficult installation and unreliable sealing, and certain professional tools are required during installation, especially when disassembling each time, it takes a certain amount of time to tighten it, which is not very convenient to use. [0003] At present, there are many quick connectors with different structures on the market. The quick docking is realized through the male connector and the female connector, but the current connectors are all non-displaceable. When there is an emergency or the installation position is not good, it needs to be rotated. It cannot be realized at the time, which brings difficulties...
