Embodiment 1

[0046] A throttle valve of this embodiment, such as Figure 1-3 As shown, it includes a valve seat 10 , a valve core 20 and a retaining ring 30 . Wherein, the valve seat 10 is provided with a valve hole 12 communicating with each other and a valve core cavity 11 for installing the valve core 20 , and the valve core 20 can move axially in the valve core cavity 11 .

[0047] Wherein, the inner diameter of the valve core cavity 11 is larger than the inner diameter of the valve hole 12 , and a transition cone surface 13 is provided between the valve core cavity 11 and the valve hole 12 .

[0048] In this embodiment, two liquid flow passages 14 radially penetrating through the wall of the valve core cavity 11 are provided along the circumferential direction near the transition cone surface 13 on the cavity wall of the valve core cavity 11 . Of course, the number of liquid flow channels 14 can be one, or more than two, preferably two.

[0049] In this embodiment, the end of the va...

Embodiment 2

[0059] Such as Figure 5 As shown, the silent throttle valve of this embodiment differs from the first embodiment in that an arc-shaped transition surface 34 is provided at the position where the inner taper hole of the retaining ring connects with the guide hole. The purpose of such setting is that when the retaining ring collides with the outer cone surface on the valve core, the arc surface where the arc-shaped transition surface is located will cause less damage to the outer cone surface, which is beneficial to improve the life of the silent throttle valve.

Embodiment 3

[0061] Such as Figure 6 As shown, a one-way throttle valve assembly of this embodiment includes a valve pipe 40, and the valve pipe 40 is provided with a valve seat installation chamber 41, and the valve seat installation chamber 41 is provided with the mute valve of the first embodiment. Throttle valve, and in the valve tube in this embodiment, filter screens 42 are provided at both ends of the throttle valve.

[0062] Preferably, the filter screen 42 in this embodiment is made of stainless steel with a mesh size of 50-150 mesh.

[0063] It should be noted that this embodiment is a specific application occasion of the silent throttle valve of Embodiment 1. The throttle valve assembly of this embodiment can be directly applied to an air conditioner, and its two ends are connected to the refrigerant pipeline of the air conditioner. . The throttle valve assembly with this structure also has the silent technical advantage of the silent throttle valve in the first embodiment, t...

Abstract

The invention relates to the technical field of throttling valves for air conditioning refrigeration, and particularly discloses a silent throttling valve and a throttling valve component. The silentthrottling valve comprises a valve seat, a valve element and a check ring, the valve element comprises a large-diameter section and a small-diameter section, and a connecting section is arranged between the large-diameter section and the small-diameter section; a guide hole matched with the small-diameter section is formed in the check ring, an inner taper hole is formed in the end, facing the valve element, of the check ring, when the valve element is located at the limit position of the side, away from a valve hole, of a valve element cavity, and a wire contact is formed between the check ring and the valve element. According to the silent throttling valve with the structure, the impact noise generated by axial movement, radial rotation and axis deviation of the valve element is effectively reduced, the valve element is lighter in weight, the valve seat is shorter in length and lower in cost.

Description

technical field [0001] The invention relates to the technical field of throttle valves for air conditioning and refrigeration, in particular to a silent throttle valve and a throttle valve assembly. Background technique [0002] After the air conditioner is turned off, the refrigerant will flow from the high-pressure part to the low-pressure part due to the change in pressure. When the refrigerant flows through the throttle valve, the throttle valve is in a non-throttle state, and the valve core is suspended in the valve seat. During the pressure balance process, the valve core will produce axial movement in the valve seat. [0003] In the prior art, the port of the valve seat restricts the valve core in the valve core cavity of the valve seat by narrowing the mouth, so as to prevent the valve core from detaching from the valve seat. For the throttle valve with this structure, due to the irregular contact between the end of the valve core and the constriction of the valve s...
