[0028] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0029] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0031] refer to Figures 1 to 6 According to a preferred embodiment of the utility model, a pipe joint capable of discharging gas in a fluid will be described in detail below. The pipe joint capable of discharging gas in a fluid comprises a joint body 10 and a gas exhaust valve body 20. The joint body 10 has a bottom port 101, a side port 102 and a top gas outlet 103. The top gas outlet 103 is arranged at the upper end of the bottom port 101 and the side port 102. In addition, the joint body 10 also forms a communication cavity 104 communicating with the bottom port 101, the side port 102 and the top gas outlet 103.

[0032] Either the bottom port 101 or the side port 102 is defined as an inlet, and the other is defined as an outlet, that is, the fluid flows in from either the bottom port 101 or the side port 102, and then flows out from the other through the connecting cavity 104. In other words, a fluid channel is formed between the bottom port 101 and the side port 102 in the connecting cavity 104. Since the specific gravity of the gas in the fluid is small when the fluid flows through the fluid channel, it will precipitate from the fluid and gradually float upward to float to the top outlet 103.

[0033] The exhaust valve body 20 is disposed on the joint body 10, so that when the exhaust valve body 20 is opened, the communication chamber 104 is connected to the outside through the top gas outlet 103, so that the gas separated from the top of the communication chamber 104 can flow out through the gas outlet. When the gas in the communication chamber 104 is released, the exhaust valve body 20 can block the top gas outlet 103 and the outside, so as to prevent the outside air from entering and mixing into the fluid.

[0034] It is understood by those skilled in the art that when the exhaust valve body 20 is opened, the communicating cavity 104

[0035] The pressure of the gas released at the top is greater than the external pressure, so the gas released at the top of the communicating cavity 104 can flow out through the top gas outlet 103 .

[0036] In one embodiment, the exhaust valve body 20 is implemented as a manual valve body. Specifically, the exhaust valve body 20 includes a guide rod 21 , a valve core 22 and an elastic member 23 .

[0037] It is worth mentioning that, in this embodiment, the top of the joint body 10 has a mounting pipe 11 extending laterally, wherein the mounting pipe 11 forms a mounting channel 1101 and the top air outlet 103 connected to the mounting channel 1101 is formed at the end.

[0038] The inner wall of the installation channel 1101 also forms a step portion, wherein the cross-sectional diameter of the installation channel 1101 from the step portion to the top air outlet 103 is smaller than the cross-sectional diameter of the installation channel 1101 from the step portion to the connecting cavity 104 formed by the joint body 10. The cross-sectional diameter of the valve core 22 is smaller than the cross-sectional diameter of the installation channel 1101 from the step portion to the connecting cavity 104 formed by the joint body 10, but larger than the cross-sectional diameter of the installation channel 1101 from the step portion to the top air outlet 103. The inner wall of the installation channel 1101 extends radially to form a mounting seat 12, wherein a connecting gap 1102 is formed between the mounting seat 12 and the inner wall of the installation channel 1101 to allow fluid to pass through.

[0039] The guide rod 21 has a limit end 211 close to the outside world and a mounting end 212 away from the outside world, wherein the mounting end 212 of the guide rod 21 is fixedly connected to the valve core 22 after passing through the mounting seat 12, wherein the elastic member 23 is maintained in a compressed state and arranged between a side surface of the mounting seat 12 close to the outside world and the limit end 211, and is sleeved on the guide rod 21, and the guide rod 21 is arranged along the axial direction of the mounting channel 1101, so that the valve core 22 tends to slide toward the outside world and press against the step portion to block the mounting channel 1101, thereby preventing outside air from flowing in from the air outlet.

[0040] It is worth mentioning that when it is necessary to manually discharge the gas in the connecting chamber 104, it is only necessary to manually press the limit end 211 of the guide rod 21, so as to drive the valve core 22 to move away from the step portion, and then the blocked installation channel 1101 can be connected with the connecting chamber 104 and the outside world again.

[0041] In other words, through such an arrangement, the user can manually exhaust the air.

[0042] Preferably, the pipe joint capable of discharging the gas in the fluid further comprises a valve cap 30 , wherein the valve cap 30 is detachably covered on the installation pipe 11 to form the outer wall of the top air outlet 103 , thereby preventing external dust and other debris from entering the installation channel 1101 .

[0043] In one example, an outer wall of the mounting pipe 11 forming the top air outlet 103 is provided with an external thread, wherein an inner wall of the valve cap 30 is provided with an internal thread matching the external thread provided on the outer wall of the top air outlet 103 .

[0044] In another embodiment of the present invention, the exhaust valve body 20 is implemented as an automatic valve body. Specifically, the exhaust valve body 20 includes a guide rod 21 , a valve core 22 and an elastic member 23 .

[0045] It is worth mentioning that, in this embodiment, the top of the joint body 10 has a mounting pipe 11 extending laterally, wherein the mounting pipe 11 forms a mounting channel 1101 and the top air outlet 103 connected to the mounting channel 1101 is formed at the end.

[0046] The inner wall of the installation channel 1101 also forms a step portion, wherein the cross-sectional diameter of the installation channel 1101 from the step portion to the top air outlet 103 is larger than the cross-sectional diameter of the installation channel 1101 from the step portion to the connecting cavity 104 formed by the joint body 10. The cross-sectional diameter of the valve core 22 is larger than the cross-sectional diameter of the installation channel 1101 from the step portion to the connecting cavity 104 formed by the joint body 10, but smaller than the cross-sectional diameter of the installation channel 1101 from the step portion to the top air outlet 103. The inner wall of the installation channel 1101 extends radially to form a mounting seat 12, wherein a connecting gap 1102 allowing fluid to pass is formed between the mounting seat 12 and the inner wall of the installation channel 1101.

[0047] The guide rod 21 has a limit end 211 close to the outside world and a mounting end 212 away from the outside world, wherein the mounting end 212 of the guide rod 21 is fixedly connected to the valve core 22 after passing through the mounting seat 12, wherein the elastic member 23 is maintained in a compressed state and arranged between the valve core 22 and the mounting end 212, and is sleeved on the guide rod 21, and the guide rod 21 is arranged along the axial direction of the mounting channel 1101, so that the valve core 22 tends to slide against the step portion in a direction away from the outside world to block the mounting channel 1101, thereby preventing outside air from flowing into the air outlet.

[0048] It is worth mentioning that when the air pressure in the communication chamber 104 is greater than a preset value and can overcome the force of the elastic member 23 on the valve core 22, the valve core 22 will be automatically pushed to the step portion, so that the installation channel 1101 can be connected with the communication chamber 104 and the outside world. In this way, automatic exhaust can be achieved.

[0049] Those skilled in the art will appreciate that the type of spring can be adjusted so that the valve core 22 can be pressed against the step portion at different pressures, thereby enabling the valve core 22 to automatically exhaust air at different air pressure values.

[0050] Furthermore, the outer wall of the bottom opening 101 at the bottom of the joint body 10 is provided with a first annular groove 105 for installing a first sealing ring 40 so as to facilitate sealing connection with other pipe fittings.

[0051] Also preferably, the side of the joint body 10 extends in the radial direction to form a connecting tube body 13, wherein the end of the connecting tube body 13 forms the side opening 102. In one embodiment, the connecting tube body is detachably mounted on the side of the joint body 10. In another embodiment, the connecting tube body 13 is formed by extending integrally from the side of the joint body 10 in the radial direction.

[0052] Preferably, the outer wall of the end of the connecting pipe body 13 forming the side opening 102 is provided with a second annular groove 106 for installing a second sealing ring 50 so as to facilitate sealing connection with other pipe fittings.

[0053] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
