AI Technical Summary

Technical Problem

The existing sleeve valve has poor noise reduction effect and only one pressure reduction process for the water flow, which cannot effectively reduce noise and improve flow performance.

Method used

A sleeve valve is designed, by providing italics at the lower part of the sleeve to form the first and second overflow channels, and through holes are provided between the italics and the sleeve to realize multiple channels of pressure reduction and noise reduction of water flow. , ensure the normal lifting and lowering control of the valve core.

Benefits of technology

After the water flow hits the italic, it is reduced and noise reduction is reduced again, which significantly improves the overall performance of the sleeve and improves the noise reduction effect without affecting the normal operation of the valve core.

[0005] A sleeve valve comprises a sleeve, a sleeve plug cavity fits with a plug-mounted valve core, the lower part of the sleeve is turned inwardly and provided with an oblique body, the upper part of the sleeve is provided with a sleeve body, a first flow channel is formed between the outer wall of the sleeve and the oblique body, a second flow channel is formed between the oblique body and the sleeve body, the second flow channel is connected to the first flow channel, a through hole corresponding to the oblique body is provided in the lower part of the sleeve, the first flow channel is connected to the through hole, and the second flow channel is connected to the sleeve plug cavity.

[0006] As a further description of the above technical solution:

[0007] The lower part of the italic body is in contact with the valve core.

[0008] As a further description of the above technical solution:

[0009] The inner side of the sleeve body is in contact with the valve core.

[0010] As a further description of the above technical solution:

[0011] The outer side of the sleeve body is contracted obliquely to form an inclined surface.

[0012] As a further description of the above technical solution:

[0013] The inclined surface is arranged parallel to the italic body.

[0014] As a further description of the above technical solution:

[0015] The opening of the second flow passage is located at the lower part of the plug cavity.

[0016] Compared with the prior art, the utility model provides a sleeve valve, which has the following beneficial effects:

[0017] 1. In the utility model, the original sleeve valve structure is improved, and a through hole is used for pressure reduction and noise reduction. The water flow impacts the inclined body and then rises and flows through the second flow channel, and is again reduced in pressure and noise, thereby improving the overall performance of the sleeve in pressure reduction and noise reduction;

[0018] 2. In the utility model, the improved design of the sleeve structure does not affect the normal lifting and lowering control and adjustment of the valve core. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a schematic diagram of the cross-sectional structure of the sleeve of the utility model;

[0020] Figure 2 This is a schematic diagram of the external structure of the sleeve of the utility model.

[0021] Legend:

[0022] 1. Sleeve; 2. Valve core; 3. Italic body; 4. Sleeve body; 5. First flow passage; 6. Second flow passage; 7. Through hole. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] See also Figure 1-Figure 2 The utility model provides a sleeve valve, including a sleeve 1, a plug cavity of the sleeve 1 fits a plug-mounted valve core 2, the lower part of the sleeve 1 is turned inwardly and provided with an oblique body 3, the upper part of the sleeve 1 is provided with a sleeve body 4, a first flow passage 5 is formed between the outer wall of the sleeve 1 and the oblique body 3, a second flow passage 6 is formed between the oblique body 3 and the sleeve body 4, the second flow passage 6 is connected to the first flow passage 5, a through hole 7 corresponding to the oblique body 3 is provided at the lower part of the sleeve 1, the first flow passage 5 is connected to the through hole 7, and the second flow passage 6 is connected to the plug cavity of the sleeve 1.

[0025] Specifically, Figure 1 As shown, the lower part of the inclined body 3 is in contact with the valve core 2, and the inner side of the sleeve body 4 is in contact with the valve core 2, so that the valve core 2 can be raised and lowered to control the flow.

[0026] Specifically, Figure 1 As shown, the outer side of the sleeve body 4 is contracted obliquely to form an inclined surface, and the inclined surface is arranged parallel to the inclined body 3 to facilitate the opening of the second flow passage 6.

[0027] Specifically, Figure 1As shown, the opening of the second flow passage 6 is located at the lower part of the plug cavity, which is convenient for the valve core 2 to rise and fall and control the flow.

[0028] Working principle:

[0029] By improving the sleeve 1 structure of the sleeve valve, when the valve core 2 descends, water enters the first flow channel 5 from the through hole 7, and then enters the second flow channel 6 along the first flow channel 5. Since the opening of the second flow channel 6 is blocked, the water flow is disconnected. When the valve core 2 rises, water enters the plug cavity of the sleeve 1 from the opening of the second flow channel 6, and the water flows.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
