Description

Technical Field

[0001] The utility model relates to the field of water treatment, and particularly to a valve core structure for a water softener. Background Art

[0002] The water softening valve is a key component of a water softener. It mainly functions to control the water flow and regulate the regeneration process. Through the water softening valve, the softening treatment of water can be achieved, removing calcium, magnesium and other ions in the water, thereby reducing the water hardness and making the water softer, which has a better effect on some scenarios that require the use of soft water, such as washing and bathing.

[0003] The water softening valve usually has the following structural components:

[0004] Valve body: It is the main part of the entire water softening valve, providing a channel for the water flow.

[0005] Valve core: It is used to control the direction, flow rate, etc. of the water flow, and realizes various functions through its movement or rotation.

[0006] Drive device: It can be a motor, an electromagnetic device, etc., used to drive the valve core to act.

[0007] Sensors: Such as flow sensors, hardness sensors, etc., used to monitor relevant parameters of the water so that the water softening valve can make corresponding adjustments.

[0008] Connection ports: Include water inlet, water outlet, regeneration liquid inlet, etc., used to connect with external pipelines.

[0009] Internal control circuit or mechanism: Used to coordinate and control the operation of each part of the water softening valve, realizing automatic control and operation logic.

[0010] Sealing components: Ensure the sealing between various parts of the valve body to prevent water leakage.

[0011] The existing water softening valve control valve core has the following disadvantages;

[0012] 1. Most of the existing water softening valve control valve cores adopt separate control of the main valve core and the salt valve core, requiring two sets of control systems.

[0013] 2. The moving seals such as the valve core and the pull rod inside the control valve are sprayed with a Teflon coating on the surface to play a lubricating role. With the restriction of the use of fluorine-containing materials in various countries, the existing Teflon coating is gradually restricted from use, and the control valve of the water softening valve needs to be updated. Content of the Utility Model

[0014] A series of simplified concepts are introduced in the utility model content section. These simplified concepts are simplified from the prior art in this field and will be further elaborated in the detailed implementation section. The utility model content section of the present utility model does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0015] The technical problem to be solved by the present utility model is to provide a water softener valve core structure that does not contain fluorine, has self-lubricating properties, and meets the requirements of PAFS certification.

[0016] To solve the above technical problem, the water softener valve core structure provided by the present utility model includes: a salt valve core 1, a main valve core 2, and a pull rod 3 that are sequentially connected in series and made of polyetheretherketone material;

[0017] The salt valve core 1 has a maximum diameter smaller than the full diameter of the main valve core 2 and is connected to the end face of the first large-diameter section of the main valve core 2;

[0018] The main valve core 2 is formed into a variable-section cylinder with larger diameters at both ends and a smaller diameter in the middle. Its small-diameter section can be aligned with different passages on the valve body through axial displacement to form different water flow passages, and at the same time, its first large-diameter section and second large-diameter section can block the remaining passages on the valve body;

[0019] The pull rod 3 is connected to the end face of the second large-diameter section of the main valve core 2 and is used to connect an external power source to push and pull the water softener valve core structure to reciprocate axially in the valve body.

[0020] Polyetheretherketone, namely Peek, has self-lubricating properties and high strength, and can also meet the requirements of PAFS certification. Polyetheretherketone can be directly injection-molded to form the water softener valve core structure of the present utility model, greatly reducing the part cost compared with the prior art of using metal surface coated with polytetrafluoroethylene.

[0021] Preferably, to further improve the water softener valve core structure, the axial length of the first large-diameter section of the main valve core 2 is greater than the axial length of the small-diameter section and greater than or equal to the axial length of the salt valve core 1.

[0022] Preferably, to further improve the water softener valve core structure, the axial length of the second large-diameter section of the main valve core 2 is greater than or equal to the axial length of the small-diameter section.

[0023] Preferably, to further improve the water softener valve core structure, the main valve core 2 is formed into a dumbbell shape.

[0024] Preferably, to further improve the water softener valve core structure, the end of the pull rod 3 away from the main valve core 2 is formed with a thread for connecting an external drive.

[0025] Preferably, the structure of the water softener valve core is further improved. The salt valve core 1 can be inserted into the main valve core 2 from the end face of the first large-diameter section of the independent valve core 2, and its insertion end is limited by the end face of the first large-diameter section of the main valve core 2 and cannot be separated from the main valve core 2.

[0026] The present invention provides a water softener valve having the water softener valve core structure described in any one of the above. The other structures of the water softener valve can be manufactured according to actual needs. The key improvement lies in using the water softener valve core structure made of polyether ether ketone of the present invention.

[0027] The present invention can at least achieve the following technical effects;

[0028] 1. The salt valve core and the main valve core of the present invention form an integrated structure. Only one set of control system is required to drive the axial displacement to close the salt valve and open different waterways. Compared with the prior art, the structure is simple and the production cost can be reduced.

[0029] 2. The present invention abandons the scheme of metal spraying Teflon coating in the prior art and is made of polyether ether ketone by injection molding or machining. The manufacturing process is simple and the production efficiency can be improved. At the same time, polyether ether ketone has self-lubricating properties and is suitable for the valve core, and meets environmental protection standards and PAFS certification.

[0030] 3. The present invention can achieve the precise linkage of the salt valve core and the main valve core. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The first embodiment;

[0042] Reference Figure 1 As shown, the present utility model provides a soft water machine valve core structure, including: a salt valve core 1, a main valve core 2, and a pull rod 3 that are sequentially connected in series and made of polyether ether ketone material;

[0043] The salt valve core 1, whose maximum diameter is smaller than the full-section diameter of the main valve core 2, is connected to the end face of the first large-diameter section of the main valve core 2;

[0044] The main valve core 2 is formed into a variable-section cylinder with large diameters at both ends and a small diameter in the middle. Its small-diameter section can be aligned with different passages 5 on the valve body 4 through axial displacement to form different water flow passages. The relatively simple implementation orientation of the passages is through holes. At the same time, its first large-diameter section and second large-diameter section can block the passages 5 on the rest of the valve body 4 of the valve body 4;

[0045] The pull rod 3 is connected to the end face of the second large-diameter section of the main valve core 2 and is used to connect an external power source to push and pull the soft water machine valve core structure to reciprocate axially in the valve body 4.

[0046] Preferably, further improving the above first embodiment, the axial length of the first large-diameter section of the main valve core 2 is greater than the axial length of the small-diameter section and greater than or equal to the axial length of the salt valve core 1. With such a design, the first large-diameter section of the main valve core 2 can block the passages 5 of multiple valve bodies 4 simultaneously.

[0047] Optionally, improving the above first embodiment, the axial length of the second large-diameter section of the valve core 2 is greater than or equal to the axial length of the small-diameter section, and the small-diameter section and the passage 5 aligned therewith form a flow path.

[0048] Preferably, further improving the above first embodiment, the main valve core 2 is formed in a dumbbell shape.

[0049] Optionally, the pull rod 3 in the above first embodiment serves as a transmission member, and a thread is formed at one end of the pull rod 3 away from the main valve core 2, and this thread is used to connect an external drive.

[0050] When the above first embodiment works, the common movement of the salt valve core 1 and the main valve core 2 can be achieved in two ways.

[0051] The first way: The front end of the salt valve core 1 is fixedly installed, and the rear end of the salt valve core 1 can be inserted into the main valve core 2 from the end face of the first large-diameter section of the main valve core 2. That is, when the main valve core 2 is pushed into different positions of the valve body 4, the length of the salt valve core 1 inserted into the first large-diameter section of the main valve core 2 is different. At the same time, one end of the salt valve core 1 inserted into the main valve core 2 is limited by the end face of the first large-diameter section of the main valve core 2 and cannot be separated from the main valve core 2. In this way, when the small-diameter section of the main valve core 2 is pushed to align with different passages, the salt valve core 1 can remain stationary. When it is necessary to close the salt valve core chamber, pushing the first large-diameter section of the main valve core 2 into the salt valve core chamber completes the closing of the salt valve core chamber.

[0052] The second way: The front end of the salt valve core 1 is not fixedly installed, and the front end of the salt valve core 1 can be pushed by the main valve core 2 to leave the salt valve core chamber. In this way, when the small-diameter section of the main valve core 2 is pushed to align with different passages, the salt valve core 1 needs to move accordingly. When it is necessary to close the salt valve core chamber, pushing the first large-diameter section of the main valve core 2 into the salt valve core chamber completes the closing of the salt valve core chamber.

[0053] In addition, it should also be understood that although the terms "first", "second", etc. can be used here to describe different elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Therefore, without departing from the teachings of the exemplary embodiments of the present invention, the first element, component, region, layer, or part discussed below can also be referred to as the second element, component, region, layer, or part.

[0054] Second embodiment;

[0055] Reference Figure 2 As shown, the present utility model provides a water softener valve and the water softener valve core structure described in the above first embodiment.

[0056] It should be further noted that the number and position of the passages 5 provided on the valve body 4 can be selected according to actual needs, but need to be coordinated with the size of the small-diameter section of the main valve core 2. For other structures of the valve body 4, as long as they can adapt to the operation principle of the water softener valve core structure of the present utility model, there are no mandatory requirements.

[0057] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present utility model belongs. It will also be understood that terms such as those defined in a general dictionary shall be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and shall not be interpreted in an ideal or overly formal sense, unless expressly defined herein.

[0058] The present utility model has been described in detail above through specific embodiments and examples, but these do not constitute a limitation to the present utility model. Without departing from the principle of the present utility model, those skilled in the art can also make many modifications and improvements, which should also be regarded as the protection scope of the present utility model.
