Description

A complete set of inlet and outlet equipment for a water pump with good sealing effect Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a complete set of inlet and outlet equipment for a water pump with good sealing effect. Background Technology

[0002] In manufacturing processes across semiconductor manufacturing, medical and pharmaceutical product manufacturing, food processing, and other industrial sectors, various fluids (such as high-purity pharmaceutical solutions and high-purity chemical reagents) are required. These fluids are transported within machinery using pumps and conduits, necessitating connections between conduits and between conduits and equipment. Insufficient or substandard sealing of these conduit connectors can lead to leakage, a situation that must be avoided. Therefore, conduit connectors with superior sealing performance are needed to prevent such issues. Currently, patent application CN201580030806.8 discloses a resin-made conduit connector, comprising a connector body, a sleeve, and fasteners. In use, the conduit is fitted onto one end of the sleeve, the other end of the sleeve is connected to the connector body, and finally, fasteners are used to further secure the conduit and sleeve to the connector body. This design further limits the insertion rate and magnification of the insertion slot to achieve a better sealing effect. However, our research has revealed certain shortcomings in this patented design. In this design, the width of the groove is significantly smaller than the width (or thickness) of the insertion part, and both the shape of the groove and the cross-sectional shape of the insertion part are rectangular. Although a certain chamfer is provided at the top of the insertion part and the opening of the groove, it is still very difficult to insert or pull out. It is not easy to insert into a deep working position when inserting, and a lot of force is required when pulling out, which is very inconvenient during installation.

[0003] The above-mentioned existing technical solutions have the following drawbacks: therefore, a simple pipe fitting structure that can realize the connection between flexible hoses and rigid pipes is needed. Summary of the Invention

[0004] The purpose of this utility model is to provide a complete set of water pump inlet and outlet equipment with good sealing effect to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A complete set of inlet and outlet equipment for a water pump with good sealing effect includes a water pump, an inlet pipe and an outlet pipe provided on the water pump, both of which are straight pipes. A pipe joint with identical structure is installed on both the inlet and outlet pipes. The pipe joint includes a sleeve, a pressure ring, and a clamp. The sleeve has internal threads, and one end of the inlet and outlet pipes connected to the pipe joint has external threads. One end of the sleeve is screwed onto the inlet / outlet pipe. The outer wall of the pressure ring has external threads that mate with the threads on the inner wall of the sleeve. The pressure ring is screwed into the inside of the sleeve. The inner wall of the pressure ring has a first dovetail groove, and the inner wall of the inlet / outlet pipe has a second dovetail groove corresponding to the first dovetail groove. The same dovetail block is inserted into the first and second dovetail grooves.

[0007] By adopting the above technical solution, when the sleeve is screwed onto the inlet / outlet pipe, the pressure ring presses against the end face of the inlet / outlet pipe, limiting the sleeve from vibrating and spinning during use. This function is achieved by the inserted dovetail block, making the pipe joint connection sufficiently secure because the spinning problem has been solved.

[0008] In a further embodiment, the outer wall of the inlet / outlet pipe is provided with an integrally formed ring, and a sealing groove is provided at one end of the ring near the pipe joint. A sealing ring is provided in the sealing groove, and one end face of the sleeve of the pipe joint is in contact with the end face of the ring.

[0009] In a further embodiment, the outer wall of the sleeve is provided with a plurality of protrusions evenly distributed axially.

[0010] By adopting the above technical solution, the hose to be connected is sleeved on the outer wall of the sleeve and then tied with a clamp. The protrusion increases the resistance, making the connection more stable. Therefore, the size of the protrusion should not be too large. More precisely, an annular groove is set on the outer wall of the sleeve, and then a protrusion is set in the annular groove so that the outer wall of the sleeve can better fit with the inner wall of the hose.

[0011] In a further embodiment, multiple clamps are provided, and the multiple clamps are tied at equal intervals to the outside of the sleeve.

[0012] In a further embodiment, a rubber ring is bonded and fixed to the side of the pressure ring near the end face of the inlet / outlet pipe.

[0013] In a further embodiment, a retaining ring is provided at the end of the sleeve away from the inlet / outlet water pipe.

[0014] By adopting the above technical solution, the flow direction of water can be blocked.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By screwing the sleeve onto the inlet / outlet pipe, the pressure ring presses against the end face of the inlet / outlet pipe, preventing the sleeve from vibrating and spinning during use. This function is achieved by inserting a dovetail block, making the pipe joint connection sufficiently secure because the spinning problem has been solved. Attached Figure Description

One end of the sleeve 41 is screwed onto the inlet pipe 2 / outlet pipe 3. The outer wall of the pressure ring 42 has external threads that mate with the threads on the inner wall of the sleeve 41. The pressure ring 42 is screwed into the inside of the sleeve 41. The inner wall of the pressure ring 42 has a first dovetail groove. The inner wall of pipe 2 / outlet pipe 3 is provided with a second dovetail groove corresponding to the first dovetail groove. The same dovetail block 5 is inserted into the first and second dovetail grooves. The outer wall of inlet pipe 2 / outlet pipe 3 is provided with an integrally formed ring. A sealing groove is provided at one end of the ring near the pipe joint 4. A sealing ring 6 is provided in the sealing groove. One end face of the sleeve 41 of the pipe joint 4 is fitted with the end face of the ring. Multiple protrusions are evenly provided axially on the outer wall of the sleeve 41. Multiple clamps 43 are provided. Multiple clamps 43 are tied at equal intervals on the outside of the sleeve 41. A rubber ring 7 is glued and fixed on the side of the pressure ring 42 near the end face of the inlet pipe 2 / outlet pipe 3. A retaining spring is provided at the end of the sleeve 41 away from the inlet pipe 2 / outlet pipe 3.

[0024] Specific implementation process: After the sleeve is screwed onto the inlet / outlet pipe, the pressure ring is used to press against the end face of the inlet / outlet pipe to limit the sleeve from vibrating and spinning during use. This function is achieved by inserting a dovetail block, making the pipe joint connection sufficiently secure because the spinning problem has been solved.
