An internally mounted anti-scaling pull-up valve core

Abstract

This utility model provides a built-in anti-scaling pull-up valve core, belonging to the field of valve core technology. It solves the problem in the existing market where, because both the valve body and valve stem are made of metal, scale will form upon contact with water. Scale buildup at the connection between the valve body and valve stem creates resistance to the valve stem's rebound, thus affecting the valve core's performance. This built-in anti-scaling pull-up valve core includes a valve stem and a valve body fitted onto the valve stem. The valve body has an installation groove, and multiple locking grooves are formed on the side wall of the installation groove for locking and limiting the valve cap during installation. An anti-scaling ring is provided at the connection between the valve body and valve stem at the bottom to prevent scale buildup at this connection. This utility model has the advantages of preventing scale buildup at the connection between the valve body and valve stem, avoiding the impact of scale on the valve stem's rebound, and improving the valve stem's rebound.

Description

Technical Field

[0001] This utility model belongs to the field of valve core technology, and relates to a valve core, particularly to a built-in anti-scaling pull-up valve core. Background Technology

[0002] The valve core is one of the important components of the control system used in faucets, valves and other fluid systems. The valve core is a valve component that uses its movement to achieve the basic functions of directional control, pressure control or flow control.

[0003] An improved valve core, with publication number CN218761494U, is disclosed in Chinese patent literature. This patent achieves a new improvement to the valve core by changing the original copper locking cap to a plastic material, thereby reducing costs while maintaining performance.

[0004] However, in actual use of valve cores, since both the valve body and valve stem are made of metal, scale will be generated after contact with water. Scale generated at the joint between the valve body and valve stem will create some resistance to the rebound of the valve stem, thus affecting the use of the valve core. Therefore, it is of great significance to design a built-in anti-scaling pull-up valve core. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing a built-in anti-scaling pull-up valve core.

[0006] The purpose of this utility model can be achieved through the following technical solution: a built-in anti-scaling pull-up valve core, including a valve stem and a valve body sleeved on the valve stem, characterized in that the valve body has an installation groove, and the side wall of the installation groove has multiple locking grooves for locking and limiting the valve cap during installation; the bottom of the valve body and the valve stem are provided with an anti-scaling ring to prevent scale from forming at the bottom of the valve body and the valve stem, and the anti-scaling ring is sleeved on the valve stem.

[0007] In the aforementioned built-in anti-scaling pull-up valve core, the anti-scaling ring is made of plastic, the valve stem is made of stainless steel, and the valve body is made of copper.

[0008] In the aforementioned built-in anti-scaling pull-up valve core, a sealing ring 1 is sleeved on the outer side of the valve body to provide a sealing effect during valve core installation. Multiple sealing rings 2 are provided between the valve body and the valve stem, forming a multi-layer sealing structure with the outer wall of the valve stem insertion part.

[0009] In the aforementioned built-in anti-scaling pull-up valve core, a slot is provided in the center portion of the inner wall of the valve body that contacts the valve stem, in order to reduce the frictional resistance between the valve body and the valve stem.

[0010] In the aforementioned built-in anti-scaling pull-up valve core, a sealing gasket is fitted at the bottom of the valve stem, and a pressure plate is embedded at the top of the sealing gasket, with the pressure plate fitted onto the valve stem.

[0011] In the aforementioned built-in anti-scaling pull-up valve core, a shaft clip is provided at the bottom of the sealing gasket, and the shaft clip is sleeved on the valve stem. The shaft clip is made of stainless steel.

[0012] In the aforementioned built-in anti-scaling pull-up valve core, the number of locking grooves is 2-6.

[0013] Compared with existing technologies, the built-in anti-scaling pull-up valve core has the following advantages:

[0014] 1. In this utility model, by setting an anti-scaling ring at the connection between the valve body and the valve stem, scale will not be generated at the connection between the valve body and the valve stem, thus avoiding the impact of scale on the resilience of the valve stem and making the valve stem more resilient.

[0015] 2. In this utility model, by opening a locking groove on the valve body and locking it in conjunction with the valve cap, compared with the existing external hexagonal locking method, the production cost of the valve body is reduced without changing the performance. Attached Figure Description

[0018] In the diagram, 1 is the valve stem; 2 is the valve body; 3 is the mounting groove; 4 is the locking groove; 5 is the anti-scalding ring; 6 is the first sealing ring; 7 is the second sealing ring; 8 is the slot; 9 is the sealing gasket; 10 is the pressure plate; and 11 is the shaft clip. Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-2As shown, this built-in anti-scaling pull-up valve core includes a valve stem 1 and a valve body 2 sleeved on the valve stem 1. The valve body 2 has an installation groove 3, and multiple locking grooves 4 are provided on the side wall of the installation groove 3 for locking and limiting the valve cap during installation. An anti-scaling ring 5 is provided at the bottom of the valve body 2 where it connects with the valve stem 1 to prevent scale from forming at the connection. The anti-scaling ring 5 is sleeved on the valve stem 1. The plastic anti-scaling ring 5 will not form scale on its surface after contact with water, so that scale will not form at the bottom of the valve body 2 and the valve stem 1. This avoids the impact of scale on the resilience of the valve stem 1 and improves the resilience of the valve stem 1. By opening the locking groove 4 on the valve body 2 to lock with the valve cap, compared with the existing external hexagonal installation method, this valve body 2 reduces the production cost of the valve body 2 without changing the performance.

[0021] Preferably, the anti-scalding ring 5 is made of plastic, the valve stem 1 is made of stainless steel, and the valve body 2 is made of copper.

[0022] Preferably, a sealing ring 6 is provided on the outer side of the valve body 2 to provide a sealing effect when the valve core is installed. Multiple sealing rings 7 are provided between the valve body 2 and the valve stem 1, forming a multi-layer sealing structure with the outer wall of the part of the valve stem 1 that penetrates through it.

[0023] Preferably, a slot 8 is provided in the center part of the inner wall of the valve body 2 that contacts the valve stem 1 to reduce the frictional resistance between the valve body 2 and the valve stem 1. By providing the slot 8, the contact area between the valve body 2 and the valve stem 1 is reduced without changing the performance of the valve body 2 and the valve stem 1. As a result, the frictional resistance between the valve body 2 and the valve stem 1 is reduced, and the resistance experienced by the valve stem 1 when sliding is reduced.

[0024] Preferably, a sealing gasket 9 is fitted at the bottom of the valve stem 1, and a pressure plate 10 is embedded at the top of the sealing gasket 9, with the pressure plate 10 fitted onto the valve stem 1.

[0025] Preferably, the bottom of the sealing gasket 9 is provided with a shaft clip 11, and the shaft clip 11 is sleeved on the valve stem 1. The shaft clip 11 is made of stainless steel.

[0026] Preferably, the number of locking grooves 4 is 2-6.
