Description

Technical Field

[0001] The utility model belongs to the technical field related to pump heads, in particular to a pump head for improving the water flow of a central air conditioner. Background Art

[0002] The pump head refers to the rest of the water pump except the engine and pump body, generally including the impeller, bearings, oil rings and sealing rotating parts (including shaft). Generally speaking, except for the motor, all accessories are part of the pump head. The pump head of a centrifugal pump refers to the outer shell that wraps the impeller and the impeller, and also includes the shaft part that drives the impeller. In a systematic way, it is the part after the motor, coupling and base are removed. In central air conditioning, in order to increase the water flow of condensed water, the corresponding pump head will be used to extract the condensed water to ensure the heat exchange of the central air conditioning.

[0003] However, the existing pump head does not have the function of quickly adjusting the water pressure inside it when in use, which will affect the water flow efficiency of the condensed water and cannot quickly increase the water flow. At the same time, when using the pump head, it is impossible to ensure the blocking state of the pump head pipe mouth position, and then when adjusting the water pressure to increase the water flow, it will cause the water inside the pipe to flow back. To this end, we provide a pump head that increases the water flow of central air conditioners to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a pump head for improving the water flow of central air conditioning. The spring pushes the sealing ball to ensure that the sealing ball can be stably located in the internal position of the ball mouth. At the same time, the length between the telescopic cylinder and the movable cylinder is adjusted to increase the water pressure and realize the increase of water flow.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a pump head for improving the water flow of a central air conditioner, comprising a main pipeline; an upper pressure shell is arranged just above the middle of the main pipeline, a telescopic cylinder bolted to the upper pressure shell is arranged just above the upper pressure shell, a moving cylinder is slidably arranged inside the telescopic cylinder, a cylinder is fixed to the upper end of the moving cylinder, and the piston end of the cylinder is tightly fitted with the inner wall of the moving cylinder, square boxes are fixed to both ends of the main pipeline, ball ports connected to the inside of the main pipeline are opened inside the square boxes, sealing balls are rotatably arranged inside the ball ports, connecting rods are fixed to the upper parts of the peripheral sides of the sealing balls, round blocks are fixed to the upper ends of the connecting rods, and springs are fixed to the upper end faces of the round blocks.

[0007] The utility model is further configured that a lower pressure shell is arranged just below the upper pressure shell, and a stamping pipe sealed and connected to the port position of the lower pressure shell is fixed on the upper part of the peripheral side of the middle part of the main pipeline.

[0008] The utility model is further configured that an elastic diaphragm connected to the upper pressure shell and the lower pressure shell is arranged between the upper pressure shell and the lower pressure shell, and two symmetrically arranged electric lifting rods are fixed to the peripheral side of the upper port of the upper pressure shell.

[0009] The utility model is further configured that a retaining ring which is slidably connected with the peripheral side of the moving cylinder is fixed to the upper end portion of the telescopic cylinder, and four positioning rods which are evenly distributed in an annular shape are fixed to the lower end surface of the retaining ring.

[0010] The utility model is further configured that the movable cylinder is slidably arranged inside the telescopic cylinder, a sealing ring is fixed on the peripheral side thereof below the retaining ring, and the peripheral side of the sealing ring is tightly fitted with the inside of the telescopic cylinder.

[0011] The utility model is further configured such that a positioning hole is provided on the upper end surface of the blocking ring at a position corresponding to the positioning rod, and the lower end of the positioning rod is slidably arranged at an inner position of the positioning hole.

[0012] The utility model is further configured that two symmetrically arranged connecting strips are fixed to the peripheral side of the moving cylinder located above the telescopic cylinder, and the connecting strips are respectively connected to the end faces of the adjacent electric lifting rods.

[0013] The utility model is further configured that the lower end surface of the movable hole is provided with a through hole connected with the interior of the square box, the connecting rod slides through the internal position of the through hole, and the round block and the spring are both arranged inside the corresponding movable hole.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the utility model is in use, the movable cylinder is controlled to move in the internal position of the telescopic cylinder, so that the movable cylinder moves the cylinder upward, thereby increasing the distance between the cylinder and the upper pressure shell. When the cylinder is working, the piston distance generated by it will become longer, thereby the cylinder will pressurize the inside of the main pipeline for a longer time, thereby making the water flow faster, thereby increasing the water flow.

[0016] 2. When the utility model is in use, the spring pushes the sealing ball so that the sealing ball can be stably located in the internal position of the ball mouth, ensuring that the sealing ball will not shake at will inside the ball mouth. Therefore, when the cylinder is punching, the water inside the main pipe will push the sealing ball, causing the sealing ball on the left side of the main pipe to move upward, and the sealing ball on the right side of the main pipe to move downward. As a result, the right side of the main pipe is blocked by the sealing ball, and water flows out from the left side of the main pipe, ensuring that the sealing ball can be stably located in the internal position of the ball mouth, and can effectively reduce the backflow of water inside the pipe.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-6The utility model is a pump head for increasing the water flow of a central air conditioner. The spring 503 pushes the sealing ball 5 to ensure that the sealing ball 5 can be stably located in the internal position of the ball mouth 105. At the same time, the length between the telescopic cylinder 3 and the movable cylinder 303 is adjusted to increase the water pressure and realize an increase in the water flow.

[0030] Specifically, the main pipeline 1; an upper pressure shell 2 is arranged just above the middle of the main pipeline 1, a telescopic cylinder 3 connected with the upper pressure shell 2 is arranged just above the upper pressure shell 2, a moving cylinder 303 is slidably arranged inside the telescopic cylinder 3, a cylinder 4 is fixed to the upper end of the moving cylinder 303, and the piston end of the cylinder 4 is tightly fitted with the inner wall of the moving cylinder 303, square boxes 102 are fixed to both ends of the main pipeline 1, and ball ports 105 connected with the inside of the main pipeline 1 are opened inside the square boxes 102, and sealing balls 5 are rotatably arranged inside the ball ports 105, sealing Connecting rods 501 are fixed to the upper parts of the sides of the blocking ball 5, and round blocks 502 are fixed to the upper ends of the connecting rods 501. Springs 503 are fixed to the upper end faces of the round blocks 502. A movable column 103 is fixed to the middle position of the upper end face of the square box 102. A movable hole 104 is provided inside the movable column 103. A through hole 106 connected to the interior of the square box 102 is provided on the lower end face of the movable hole 104. The connecting rod 501 slides through the internal position of the through hole 106, and the round block 502 and the spring 503 are both arranged inside the corresponding movable holes 104.

[0031] The operation process of this embodiment is as follows: through the arrangement and use of the above-mentioned structure, when it is necessary to set the right end of the main pipe 1 in the water source, and connect the left end of the main pipe 1 with the end of the central air conditioner, when the water source flows in the internal position of the pipe, the cylinder 4 can be controlled to work, thereby the cylinder 4 will punch the inside of the moving cylinder 303, so that the internal gas of the telescopic cylinder 3 and the moving cylinder 303 is compressed, and then the water in the main pipe 1 is compressed, so that the water inside the main pipe 1 can be pushed quickly, thereby increasing the water flow, and at the same time, the spring 503 pushes the blocking ball 5, so that the blocking ball 5 can be stably located in the internal position of the ball mouth 105, ensuring that the blocking ball 5 will not arbitrarily move inside the ball mouth 105 The cylinder 4 is shaken, so when the cylinder 4 is punching, the water inside the main pipe 1 will push the blocking ball 5, so that the blocking ball 5 on the left side of the main pipe 1 moves upward, and the blocking ball 5 on the right side of the main pipe 1 moves downward, thereby the right side of the main pipe 1 is blocked by the blocking ball 5, and water flows out from the left side of the main pipe 1. At the same time, when it is necessary to increase the water flow rate, the moving cylinder 303 can be controlled to move in the internal position of the telescopic cylinder 3, so that the moving cylinder 303 will move the cylinder 4 upward, thereby increasing the distance between the cylinder 4 and the upper pressure shell 2, so that when the cylinder 4 is working, the piston distance generated by it will become longer, thereby the cylinder 4 will prolong the pressurization time of the inside of the main pipe 1, thereby making the water flow faster, thereby increasing the water flow rate. Specific embodiment 2

[0033] See also Figure 4 , 5 On the basis of the first specific embodiment, the electric lifting rod 201 works so as to stably control the length between the telescopic cylinder 3 and the moving cylinder 303 .

[0034] Specifically, a lower pressure shell 202 is arranged directly below the upper pressure shell 2, a stamping tube 101 is fixed to the upper part of the peripheral side of the middle part of the main pipeline 1 and is sealedly connected to the port position of the lower pressure shell 202, an elastic diaphragm 203 is arranged between the upper pressure shell 2 and the lower pressure shell 202 and is bolted to the two, two symmetrically arranged electric lifting rods 201 are fixed to the peripheral side of the upper port of the upper pressure shell 2, and two symmetrically arranged connecting strips 306 are fixed to the peripheral side of the moving cylinder 303 located above the telescopic cylinder 3, and the connecting strips 306 are respectively connected to the end faces of the adjacent electric lifting rods 201.

[0035] The operation process of this embodiment is as follows: when it is necessary to stably adjust the length between the telescopic cylinder 3 and the movable cylinder 303, the electric lifting rod 201 can be controlled to work, whereby the electric lifting rod 201 will push the connecting strip 306 to move upward, thereby pushing the connecting strip 306 to directly drive the movable cylinder 303 to slide in the internal position of the telescopic cylinder 3, whereby the length between the movable cylinder 303 and the telescopic cylinder 3 is stably increased, and at the same time, the space between the upper pressure shell 2 and the lower pressure shell 202 is blocked by the elastic diaphragm 203 to prevent water from flowing into the upper pressure shell 2. Specific embodiment three

[0037] See also Figure 5 On the basis of the first specific embodiment, the positioning rod 302 limits the position of the movable cylinder 303 to ensure that the movable cylinder 303 and the telescopic cylinder 3 will not be misaligned.

[0038] Specifically, a retaining ring 301 is fixed to the upper end portion of the telescopic cylinder 3 and is slidably connected to the circumference of the moving cylinder 303. Four positioning rods 302 are fixed to the lower end face of the retaining ring 301 and are evenly distributed in a ring shape. The moving cylinder 303 is slidably set on the circumference of the telescopic cylinder 3 and a blocking ring 304 is fixed below the retaining ring 301. The circumference of the blocking ring 304 is tightly fitted with the interior of the telescopic cylinder 3. Positioning holes 305 are opened on the upper end face of the sealing ring 304 at the position corresponding to the positioning rod 302, and the lower end of the positioning rod 302 is slidably set inside the positioning hole 305.

[0039] The operation process of this embodiment is: the blocking ring 304 is limited by the retaining ring 301 to ensure that the lower end of the moving cylinder 303 is stably located in the internal position of the telescopic cylinder 3. Therefore, when the moving cylinder 303 slides in the internal position of the telescopic cylinder 3, the moving cylinder 303 will drive the blocking ring 304 to move inside the telescopic cylinder 3, and will make the blocking ring 304 slide along the positioning rod 302 through the positioning hole 305. At the same time, the positioning rod 302 is in the positioning hole 305, so it will limit the blocking ring 304 to ensure that the moving cylinder 303 will not rotate arbitrarily in the internal position of the telescopic cylinder 3.
