Furthermore, they have weak resistance to alternating stress, structural rigidity, and safety. Modular and standardized design is also difficult to achieve, which makes it difficult to significantly reduce leakage risk, reduce downtime, extend the life of key components, and improve the safety factor, thus failing to provide a solid guarantee for the long-term stable operation of the pump. Their practicality is relatively limited. Utility Model Content

[0014] The following is in conjunction with the appendix Figures 1-3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0015] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] Example 1:

[0018] Please see Figures 1-3 The present invention relates to a ceramic plunger pump, comprising a valve box body 1, a valve seat 2 sealed and fitted inside the lower part of the valve box body 1, a rubber ball 3 sealed and connected at the center of the valve seat 2, the top of the rubber ball 3 floatingly contacting the bottom of the valve core 4, a valve cover 5 provided on the top of the valve box body 1, and a retaining bracket 6 provided on the upper part of the outer wall of the valve box body 1, the retaining bracket 6 facilitating the clamping of all parts and forming a seal.

[0019] The top center of the retaining bracket 6 is threaded with a fastening bolt 7, the top of the valve body 1 is threaded with bolts 8, the valve body 1 and the valve cover 5 are threaded with fastening bolts 7 at the center, and the valve body 1 and the valve cover 5 are connected by bolts 8 around the perimeter. Bolts 8 provide a solid guarantee for the long-term stable operation of the pump.

[0020] A spring is fixedly connected to the bottom of the valve cover 5, and the spring is sleeved on the upper part of the outer wall of the valve core 4. The retaining bracket 6 is set in an inverted U-shape.

[0021] The working principle of a ceramic plunger pump based on Embodiment 1 is as follows:

[0022] During use, the valve body 1 uses the valve seat 2 as a sealing base, the rubber ball 3 as the opening and closing core, the valve core 4 as the guiding and limiting element, the valve cover 5 as a spring seat and guide hole, and the locking bracket 6 as the final clamping unit to press all parts together and form a seal. When the valve body 1 is working, the liquid pressure pushes up the rubber ball 3 and the valve core 4 to open and allow flow. When the pressure drops, the spring on the outer wall of the valve core 4 pushes the valve core 4 back to the rubber ball 3, making it fit tightly against the valve seat 2, thereby achieving closure and sealing and ensuring one-way liquid flow. At the same time, the preload is controllable through the fastening bolts 7 and four sets of bolts 8, which improves the resistance to alternating stress, structural rigidity, and safety. It also achieves modular and standardized design, thereby significantly reducing leakage risk, reducing downtime, extending the life of key components, and improving the safety factor, providing a solid guarantee for the long-term stable operation of the pump.

[0023] This utility model provides an improved ceramic plunger pump, which achieves controllable preload through fastening bolts 7 and four sets of bolts 8, thereby improving resistance to alternating stress, structural rigidity, and safety. It also realizes modular and standardized design, which significantly reduces leakage risk, reduces downtime, extends the life of key components, and improves the safety factor, providing a solid guarantee for the long-term stable operation of the pump.
