Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and in particular to a high-strength anti-torsion valve core. Background Technology

[0002] The valve core is a valve component that enables basic functions such as directional control, pressure control, or flow control through its movement. Currently, the valve core has a valve stem sleeve that can be rotatably mounted at the top of the housing, a valve seat mounted at the bottom of the housing, and a ceramic movable sleeve that can move in the middle of the housing cavity. The valve stem sleeve has a valve stem inserted through its center, and the valve stem has two opposing slots in its middle section. The valve stem sleeve has a matching protrusion for each slot. The valve stem is mounted on the valve stem sleeve by the cooperation of the slots and protrusions. The bottom of the valve stem inserts into the middle of the housing cavity and can move the ceramic movable sleeve to adjust the relative position between the two inlets and one outlet of the valve seat, thereby achieving liquid flow control.

[0003] However, this structure, which uses a combination of bayonet and protrusion to connect the valve stem to the valve stem sleeve, has poor torsional resistance and is prone to breakage, resulting in a short service life for the valve core. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength anti-torsion valve core.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength anti-torsion valve core includes a housing, a valve stem, a valve stem sleeve, and a fixed shaft. The housing has a cavity with openings at both the upper and lower ends. The valve stem sleeve is rotatably mounted in the upper part of the cavity. The valve stem sleeve has a cavity with openings at both the upper and lower ends and two through-holes communicating with the cavity on opposite sides of its outer periphery. The housing has a strip-shaped through-hole corresponding to each through-hole along the rotation direction of the valve stem sleeve. The middle section of the valve stem is housed in the cavity, and the valve stem has a positioning port through-hole on both sides in the middle section. The middle section of the fixed shaft passes through the two through-holes and the positioning port, allowing the valve stem to be oscillatingly mounted on the valve stem sleeve. Each end of the fixed shaft passes through the strip-shaped through-hole and can move along the strip-shaped through-hole as the valve stem and valve stem sleeve rotate.

[0007] As a further technical solution of this utility model: a high-strength anti-torsion valve core includes a ceramic movable sleeve and a valve seat. The valve seat is hung at the lower end of the outer shell to block the lower opening of the shell cavity. The ceramic movable sleeve is movably provided in the lower part of the shell cavity. The top of the valve stem passes through the upper opening of the shell cavity, and the bottom of the valve stem can drive the ceramic movable sleeve to move in the shell cavity.

[0008] As a further technical solution of this utility model: the outer shell includes a main cylindrical shell and an upper cover shell installed on the top of the main cylindrical shell. The upper cover shell has a cover part that is embedded with the top of the main cylindrical shell and a cylindrical part integrally connected above the cover part. The strip-shaped opening is provided on both sides of the outer periphery of the cylindrical part.

[0009] As a further technical solution of this utility model: the outer periphery of the cylindrical part has two partition areas between two strip-shaped openings, and the cover part extends inward to form a block in the area corresponding to one of the partition areas.

[0010] As a further technical solution of this utility model: the bottom of the valve stem sleeve extends outward from one port to the other port with a limiting edge and a limiting port is formed between the two ends of the limiting edge, and the limiting port faces the position of the stop block, so that when the valve stem drives the valve stem sleeve to rotate, either end of the limiting edge can abut against the stop block, thereby achieving a limiting effect.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a high-strength anti-torsion valve core through the cooperation between the outer shell, valve stem, valve stem sleeve and fixed shaft, with the fixed shaft connecting the valve stem and valve stem sleeve, and the two ends of the fixed shaft can move along the strip-shaped through-holes on both sides of the outer shell, so as to achieve high-strength anti-torsion while playing a rotation limit role, thus making the service life of the valve core longer.

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0018] Please see Figure 1 , Figure 2A high-strength anti-torsion valve core includes a housing 10, a valve stem 20, a valve stem sleeve 30, a ceramic movable sleeve 40, a valve seat 50, and a fixed shaft 60. The housing 10 has a cavity 101 with openings at both the upper and lower ends. The valve seat 50 is hung at the lower end of the housing 10 to seal the lower opening of the cavity 101. The valve stem sleeve 30 is rotatably mounted in the upper part of the cavity 101, and the ceramic movable sleeve 40 is movably mounted in the lower part of the cavity. (See reference [reference needed]) Figure 4 The valve stem sleeve 30 is provided with a sleeve cavity 31 with openings at the upper and lower ends, and two through holes 32 that communicate with the sleeve cavity 31 are opened on opposite sides of its outer periphery. The outer shell 10 is provided with a strip-shaped through hole 102 corresponding to each through hole 32 along the rotation direction of the valve stem sleeve 30. The middle section of the valve stem 20 is housed in the sleeve cavity 31, the top of the valve stem 20 passes through the upper opening of the shell cavity 101, and the bottom of the valve stem 20 can drive the ceramic movable sleeve 40 to move within the shell cavity 101.

[0019] The valve stem 20 has a positioning port 21 that extends through both sides in the middle section; the middle section of the fixed shaft 60 passes through the two ports 32 and the positioning port 21, allowing the valve stem 20 to be swung onto the valve stem sleeve 30; each end of the fixed shaft 60 is inserted into a strip-shaped through-hole 102, and can move along the strip-shaped through-hole 102 as the valve stem 20 and valve stem sleeve 30 rotate, thus connecting the valve stem 20 and valve stem sleeve 30 with the fixed shaft 60. The fixed shaft 60 has stronger anti-torsion capability, which can extend the service life of the valve core, and the fixed shaft 60 and the strip-shaped through-hole 102 cooperate to achieve a limiting effect.

[0020] Furthermore, in this embodiment, in conjunction with reference to... Figure 3 , Figure 5 The outer shell 10 includes a main cylindrical shell 11 and an upper cover shell 12 installed on the top of the main cylindrical shell 11. The upper cover shell 12 has a cover portion 121 that fits into the top of the main cylindrical shell 11 and a cylindrical body portion 122 integrally connected above the cover portion 121. Strip-shaped openings 102 are provided on both sides of the outer periphery of the cylindrical body portion 122. Two partition areas 123 are formed between the two strip-shaped openings 102 on the outer periphery of the cylindrical body portion 122. The cover portion 121 is located at... The area corresponding to the partition 123 extends inward to form a stop 124; the bottom of the valve stem sleeve 30 extends outward from the location of one port 32 to the location of another port 32 with a limiting edge 33 and a limiting port 34 is formed between the two ends of the limiting edge 33, and the limiting port 34 faces the location of the stop 124, so that when the valve stem 20 drives the valve stem sleeve 30 to rotate, either end of the limiting edge 33 can abut against the stop 124, thereby achieving a limiting effect and improving the torsional strength.

[0021] Understandably, the method of using the high-strength anti-torsion valve core of this utility model is as follows: push, pull, or rotate the valve stem 20 to drive the ceramic movable sleeve 40 to move within the shell cavity 101, so that the water passage groove of the ceramic movable sleeve 40 is connected only to the outlet of the valve seat 50, or to the outlet of the valve seat 50 and any inlet, or to the outlet of the valve seat 50 and both inlets. When rotating the valve stem 20, as the valve stem 20 and the valve stem sleeve 30 rotate, the fixed shaft 60 moves along the strip-shaped through-hole 102, which has a limiting effect and improves the anti-torsion capability.

[0022] In summary, the high-strength anti-torsion valve core of this utility model achieves high-strength anti-torsion while also providing rotational limiting effect through the cooperation between the outer shell 10, valve stem 20, valve stem sleeve 30 and fixed shaft 60. The fixed shaft 60 connects the valve stem 20 and valve stem sleeve 30, and the two ends of the fixed shaft 60 can move along the strip-shaped through-holes 102 on both sides of the outer shell 10, thus achieving high-strength anti-torsion and extending the service life of the valve core.
