Abstract
Description
Technical Field
[0001] This utility model relates to the field of controllers, and more specifically to a water pump pressure controller. Background Technology
[0002] In some hydraulic systems, it is necessary to control the hydraulic pressure to ensure safe and stable operation. Water pump pressure controllers are the main equipment for stabilizing system pressure. Currently, most existing pressure controllers have fixed inlet and outlet interfaces, which results in poor installation flexibility in different application scenarios, especially in confined and enclosed environments, causing significant installation inconvenience. Utility Model Content
[0003] This utility model provides a water pump pressure controller that can change the orientation of the water outlet, making it easier to install.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A water pump pressure controller includes a main pipe with an inlet pipe on its middle side, and both ends of the main pipe are rotatably connected to a draining mechanism, the opening and closing of which is controlled by hydraulic pressure inside the main pipe.
[0005] The drainage mechanism includes a side tube coaxially rotatably connected to the end of the main pipe, and a drainage pipe is vertically provided on the side of the side tube.
[0006] A piston block slides inside the side tube, and a spring is provided between the piston block and the outer end of the side tube.
[0007] Both side tubes have threaded adjustment screws at their outer ends.
[0008] Both adjusting screws have knobs fixed to their outer ends.
[0009] The inner ring of the inner port of the side tube is chamfered.
[0010] The side tube is equipped with a stepped sleeve at the main tube.
[0011] The stepped sleeve is provided with multiple annular grooves for installing sealing rings.
[0012] Both ends of the main tube are fixed with end plates, and two semi-circular plates are symmetrically installed on the end plates to limit the movement of the step sleeve.
[0013] There is a gap between the semi-ring plate and the outer side of the side tube.
[0014] The beneficial effects of this utility model are: By rotating the side tube inside the main tube, the orientation of the outlet tube can be changed, thereby facilitating installation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] The following is combined Figure 1-3 A detailed description of a water pump pressure controller is provided below: A water pump pressure controller includes a main pipe 1 with an inlet pipe 2 on the middle side, and both ends of the main pipe 1 are rotatably connected to a draining mechanism, the opening and closing of which is controlled by hydraulic pressure inside the main pipe 1.
[0019] The drainage mechanism includes a side pipe 5 coaxially rotatably connected to the end of the main pipe 1, and a drainage pipe 6 is vertically provided on the side of the side pipe 5.
[0020] A piston block 7 slides inside the side tube 5, and a spring 8 is provided between the piston block 7 and the outer end of the side tube 5.
[0021] When in use, the inlet pipe 2 is connected to the water pump, so that the water pump sends water at high pressure to the main pipe 1 through the inlet pipe 2, forming a water chamber in the main pipe 1. When the water pressure in the water chamber can push the piston block 7 to overcome the elastic force of the spring 8 and move away from the main pipe 1, the outlet pipe 6 is connected to the water chamber, and the outlet pipe 6 can then flow out the water in the water chamber at high pressure. When the water pressure in the water chamber decreases, the elastic force of the spring 8 will push the piston block 7 to slide towards the main pipe 1, thereby blocking the outlet pipe 6 and closing the outlet pipe 6 to ensure the pressure of the water flowing out of the outlet pipe 6. When it is necessary to adjust the orientation of the outlet pipe 6, simply rotate the side pipe 5 inside the main pipe 1 to change the orientation of the outlet pipe 6, thus facilitating installation in a relatively small and enclosed environment. Meanwhile, the two outlet pipes 6 enable the controller to output from both ends simultaneously.
[0022] Further: Both side tubes 5 have threaded connections to adjusting screws 9 at their outer ends.
[0023] By rotating the adjusting screw 9, the adjusting screw 9 can be moved axially at the outer end of the side tube 5, and then the inner end of the adjusting screw 9 can be moved inside the side tube 5, thereby restricting the position of the piston block 7, and thus achieving manual control of closing the liquid outlet pipe 6 on the corresponding side.
[0024] Further: The adjustment screws 9 are convenient to rotate by fixing knobs at the outer ends of both adjustment screws 9.
[0025] Further: By providing a chamfer at the inner ring of the inner port of the side pipe 5, it is easier for water in the main pipe 1 to flow into the side pipe 5.
[0026] Further: The side tube 5 is provided with a stepped sleeve 4 at the main tube 1.
[0027] The stepped sleeve 4 is provided with multiple annular grooves for installing sealing rings.
[0028] Both ends of the main pipe 1 are fixed with end plates 3, and two semi-circular plates 10 are symmetrically installed on the end plates 3 to limit the step sleeve 4.
[0029] By setting the step sleeve 4, the outer diameter of the side pipe 5 located inside the main pipe 1 is larger than that of the part outside the main pipe 1, thus forming a step. Then, two semi-circular plates 10 are installed on the end plate 3 to intercept the step and prevent the side pipe 5 from being pushed out of the main pipe 1 by water pressure. At the same time, by installing sealing rings in multiple annular grooves, a seal is formed between the stepped sleeve 4 and the main pipe 1, thereby preventing water from flowing out through the gap between the two. Furthermore, by providing a gap between the semi-ring plate 10 and the outer surface of the side tube 5, it is possible to prevent the side tube 5 from contacting the semi-ring plate 10 when it rotates, thus avoiding affecting the rotation of the side tube 5.
[0030] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
