[0001] This utility model belongs to the field of pump and valve assembly technology, specifically a pump and valve assembly that is easy to maintain. Background Technology

[0002] A pump-valve assembly is an integrated system consisting of a pump, valves, and related pipelines and connectors. It uses a pump to provide power for fluid transport and valves to control flow rate, pressure, and direction, achieving functions such as fluid transmission, distribution, and regulation. It is widely used in water supply and drainage, chemical, and energy fields, and can improve the efficiency and stability of fluid control systems.

[0003] Currently, existing pump valve assemblies are usually composed of a pump valve assembly body and a sealing ring. However, the service life of the pump valve assembly is reduced by continuous high pressure over a long period of time. Therefore, it is necessary to return it to the factory for replacement every once in a while. Since replacing the sealing ring is very cumbersome and the pressure needs to be readjusted, it greatly increases the workload of the staff. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a pump valve assembly that is easy to maintain. It solves the problem that the existing pump valve assemblies are usually composed of a pump valve assembly body and a sealing ring. However, the service life of the pump valve assembly is reduced when it is continuously under high pressure for a long time. Therefore, it needs to be returned to the factory for replacement every once in a while. Since replacing the sealing ring is very cumbersome and the pressure needs to be readjusted, it greatly increases the workload of the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pump valve assembly that is easy to maintain, comprising a pump valve assembly body, wherein the pump valve assembly body has several positioning grooves, and a positioning block is slidably engaged in the positioning grooves. A sealing ring is connected to the pump valve assembly body, and the positioning block is fixedly installed at the bottom of the sealing ring. The pump valve assembly body has several inner cavities, with two inner cavities forming a group. Two slots are provided on the positioning block, and the positions of the slots correspond to the inner cavities. A telescopic rod is installed in the inner cavity, and a spring is sleeved on the telescopic rod. A locking block is fixedly installed at the end of the telescopic rod, and the locking block is engaged in the slot. Corresponding mounting grooves are provided on the pump valve assembly body and the sealing ring. A connecting column is fixedly installed in the mounting groove, and a main output hole is provided on the connecting column.

[0006] As a further embodiment of this utility model: the sealing ring is provided with a plurality of fixing grooves, and a plunger is installed in the fixing groove.

[0007] As a further embodiment of this utility model: the sealing ring has several slots, and a one-way valve is installed in the slot.

[0008] As a further embodiment of this utility model: a first throttle and a second throttle are respectively installed on the pump valve assembly body, and the first throttle and the second throttle are respectively connected to the low-pressure valve and the high-pressure valve inside the pump valve assembly body.

[0009] As a further embodiment of this utility model: a plurality of connecting posts 2 are installed on the pump valve assembly body, and an input hole is provided on the connecting posts 2.

[0010] As a further embodiment of this utility model: a pressure gauge is installed on the pump valve assembly body, and a sealing ring is installed at the connection between the pump valve assembly body and the sealing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This easy-to-maintain pump valve assembly, through the setting of a sealing ring, a retaining block, a spring, and a telescopic rod, allows for easy replacement of the sealing ring when it is damaged due to high pressure after prolonged operation. The operator holds the sealing ring with both hands and moves it upwards. Since the positioning block is connected to the sealing ring, the sealing ring moves the positioning block. As the positioning block moves upwards within the positioning groove, it presses against the retaining block. The pressure generated by this pressing causes the retaining block to move and separate from the groove. The movement of the retaining block presses against the telescopic rod and the spring. The elastic force generated by the spring is transmitted to the retaining block. Once the sealing ring has separated the positioning block from the positioning groove, a new sealing ring can be reinstalled. During reinstallation, when the groove aligns with the inner cavity, the spring force causes the retaining block to re-engage within the groove. This eliminates tedious disassembly and assembly steps, facilitating subsequent maintenance.

[0013] 2. This easy-to-maintain pump and valve assembly, equipped with a throttle handle, a plunger, and a pressure gauge, connects the entire device to the eight-hole plunger pump during operation. When adjusting the low pressure, the operator rotates the throttle handle to control the internal low-pressure valve. When adjusting the high pressure, the operator rotates the throttle handle to control the high-pressure valve. During the adjustment of low and high pressure, the pressure gauge accurately controls the appropriate pressure, avoiding significant errors. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a pump valve assembly that is easy to maintain, including a pump valve assembly body 1, a pressure gauge 11 installed on the pump valve assembly body 1, and a sealing ring 15 installed at the connection between the pump valve assembly body 1 and the sealing ring 2. Because of the installation of the sealing ring 15, the gap between the pump valve assembly body 1 and the sealing ring 2 can be blocked by the sealing ring 15, preventing gas leakage in subsequent operations and improving the stability of operation.

[0021] Several connecting posts 10 are installed on the pump valve assembly body 1, and the connecting posts 10 are provided with input holes.

[0022] The pump valve assembly body 1 is equipped with a first handle 8 and a second handle 9. The first handle 8 and the second handle 9 are respectively connected to the low-pressure valve and the high-pressure valve inside the pump valve assembly body 1. Because the first handle 8 and the second handle 9 are installed, the low-pressure valve and the high-pressure valve inside the pump valve assembly body 1 can be freely adjusted through the first handle 8 and the second handle 9, so that the low pressure or high pressure can be freely adjusted.

[0023] The pump valve assembly body 1 has several positioning grooves 14, and positioning blocks 16 are slidably engaged in the positioning grooves 14. A sealing ring 2 is connected to the pump valve assembly body 1. The sealing ring 2 has several fixing grooves 3, and a plunger 4 is installed in the fixing grooves 3. The sealing ring 2 has several slots 7, and a one-way valve 6 is installed in the slots 7. Because of the installation of the plunger 4, when the entire device is connected to the eight-hole plunger pump through the plunger 4, the mechanical energy is converted into the pressure energy of the medium through reciprocating motion, which drives the medium to flow in the pump valve assembly, thereby achieving pressure increase or pressure decrease.

[0024] The positioning block 16 is fixedly installed at the bottom of the sealing ring 2. The pump valve assembly body 1 has several inner cavities 17, with two inner cavities 17 forming a group. The positioning block 16 has two slots 18, and the positions of the slots 18 correspond to the inner cavities 17. A telescopic rod 20 is installed in the inner cavity 17, and a spring 21 is sleeved on the telescopic rod 20. Because of the spring 21, when the sealing ring 2 moves the positioning block 16, the positioning block 16 will squeeze the locking block 19. The pressure generated by the squeezing of the locking block 19 will cause the locking block 19 to move and separate from the slot 18. The movement of the locking block 19 will squeeze the telescopic rod 20 and the spring 21. The elastic force generated by the squeezing of the spring 21 will be transmitted to the locking block 19. During the reinstallation process, when the slot 18 corresponds to the inner cavity 17, the elastic force generated by the spring 21 will cause the locking block 19 to re-lock into the slot 18, eliminating the tedious disassembly and assembly steps and facilitating subsequent maintenance.

[0025] A locking block 19 is fixedly installed at the end of the telescopic rod 20. The locking block 19 is engaged in the slot 18. The pump valve assembly body 1 and the sealing ring 2 are provided with corresponding mounting slots 13. A connecting column 5 is fixedly installed in the mounting slot 13. A total output hole 12 is provided on the connecting column 5.

[0026] The working principle of this utility model is as follows: When the pump valve assembly body 1 has been working for a long time, the internal components of the sealing ring 2 are damaged due to high pressure and need to be replaced. The operator holds the sealing ring 2 with both hands and moves it upward. Since the positioning block 16 is connected to the sealing ring 2, the sealing ring 2 will move the positioning block 16. When the positioning block 16 moves upward in the positioning groove 14, it will squeeze the locking block 19. The pressure generated by the squeezing of the locking block 19 will cause the locking block 19 to move and separate from the locking groove 18. The movement of the locking block 19 will squeeze the telescopic rod 20 and the spring 21. The elastic force generated by the squeezing of the spring 21 will be transmitted to the locking block 19. After the sealing ring 2 drives the positioning block 16 to separate from the positioning groove 14, the new sealing ring 2 can be reinstalled. During the reinstallation process, when the position of the locking groove 18 corresponds with the inner cavity 17, the elastic force generated by the spring 21 will cause the locking block 19 to re-lock into the locking groove 18.

[0027] During operation, the entire device is first connected to the eight-hole plunger pump via plunger 4. When it is necessary to adjust the low pressure, the operator turns the first handle 8 to control the switch of the internal low pressure valve. When it is necessary to adjust the high pressure, the operator turns the second handle 9 to control the switch of the high pressure valve in the pump valve assembly 1. During the adjustment of low and high pressure, the appropriate pressure can be accurately controlled by the pressure gauge 11.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
