A two-position two-way valve structure

Abstract

This utility model belongs to the field of fluid control technology, specifically disclosing a two-position two-way valve structure. The two-position two-way valve structure includes a valve core, a first valve sleeve, a second valve sleeve, a valve body, a sealing ring, and a spring. The first and second valve sleeves are installed in the valve body mounting hole, and the valve core is axially movable within the first and second valve sleeves. The spring acts between the valve core and the second valve sleeve. The valve core has a first sealing surface and a guide groove; the first valve sleeve has a second sealing surface and a first fluid channel; the second valve sleeve has a second fluid channel. The valve core has two working positions: in the first position, the first sealing surface and the second sealing surface abut against each other, cutting off the fluid passage; in the second position, the guide groove connects the first and second fluid channels, establishing a fluid passage. By integrating the core components into a single mounting hole, the problem of large size and low reliability of traditional split-type valves is solved, achieving miniaturization, integration, and high reliability of the two-position two-way valve.

Description

Technical Field

[0001] This utility model belongs to the field of fluid control technology, specifically relating to a two-position two-way valve structure. Background Technology

[0002] Currently, some specialized industrial sectors, such as manned submersibles and flight equipment cabins, impose strict limitations on the weight and size of their hydraulic components. Many handheld hydraulic tools, such as handheld demolition tools, require compact size and ease of operation due to their handheld nature. Most of the applications described above utilize conventional industrial valves paired with valve blocks. Typically, the actuator and control valve assembly are separate structures connected by pipelines, resulting in a bulky product structure and compromising reliability and ease of operation.

[0003] Therefore, it is necessary to provide a product structure that is simpler and more compact. Through optimized structure, the fluid control valve assembly can be made smaller, thereby improving reliability and ease of operation. Utility Model Content

[0004] The purpose of this utility model is to provide a two-position two-way valve to solve the problems of large size and inconvenient operation of existing two-position two-way valves.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a two-position two-way valve structure, including a valve core, a first valve sleeve, a second valve sleeve, a valve body, a sealing ring, and a spring; characterized in that: the valve body is provided with a mounting hole, the first valve sleeve and the second valve sleeve are installed in the mounting hole, and the valve core is axially movable and placed in the center hole of the first valve sleeve and the center hole of the second valve sleeve; the spring acts between the valve core and the second valve sleeve; the valve core is provided with a first sealing surface and a guide groove, the first valve sleeve is provided with a second sealing surface and a first fluid channel, and the second valve sleeve is provided with a second fluid channel; the valve core has a first working position and a second working position: when it is in the first working position, the first sealing surface and the second sealing surface abut and seal, thereby cutting off the fluid passage; when it is in the second working position, the guide groove connects the first fluid channel and the second fluid channel, thereby establishing a fluid passage.

[0006] Preferably, the valve sleeve 2 is provided with an air guide hole 1 for balancing the air pressure in the cavity.

[0007] Preferably, the valve body is provided with a fluid channel three communicating with the fluid channel one, a fluid channel four communicating with the fluid channel two, and a vent two communicating with the vent one.

[0008] Preferably, the sealing ring is installed in the sealing ring grooves of valve sleeve one and valve sleeve two, and cooperates with the valve body and valve core to isolate different fluid channels.

[0009] The above solutions allow for a more compact valve assembly structure, reducing weight and making it particularly suitable for applications with stringent space and weight requirements, such as submarines and handheld tools. The integrated design allows the valve assembly to be directly mounted on the actuator, reducing piping connections and improving product reliability, ease of operation, and flexibility. The addition of an air guide port effectively eliminates the adverse effects of spring chamber pressure changes on valve core movement, ensuring smooth and reliable operation. In summary, this two-position two-way valve structure is simple, compact, and functionally stable, effectively meeting diverse industrial design needs and demonstrating promising application prospects.

Detailed Implementation

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Specifically, Figures 1 to 3 The diagram shown illustrates the structure of this two-position two-way valve in different states. Figures 4 to 7 This is a schematic diagram of the components of the two-position two-way valve structure.

[0020] like Figure 2 As shown, the structure of the two-position two-way valve includes a valve core (1), a first valve sleeve (2), a sealing ring (3), a second valve sleeve (4), a spring (5), and a valve body (6). The valve body (6) is provided with a mounting hole (604), and the first valve sleeve (2) and the second valve sleeve (4) are installed and fixed in the mounting hole (604) in abutment. The valve core (1) is axially movable and placed in the central hole of the first valve sleeve (2) and the second valve sleeve (4). One end of the spring (5) is placed in the central hole of the valve core (1) and abuts against the end face of the central hole, and the other end is placed in the bottom end face of the central hole of the second valve sleeve (4), thereby providing a force to the valve core (1) towards the first valve sleeve (2).

[0021] like Figure 4 As shown, the valve core (1) is machined with a conical sealing surface (102) and an annular guide groove (101); Figure 5 As shown, the valve sleeve (2) is machined with a sealing surface (202) and a fluid passage (201); Figure 6 As shown, the valve sleeve 2 (4) is machined with a fluid channel 2 (401) and a vent hole 1 (402) for balancing the air pressure in the spring chamber; as Figure 7 As shown, the valve body is machined with fluid channel three (602) and fluid channel four (601) as well as air guide hole two (603).

[0022] pass Figure 2 As can be seen, fluid channel one (201) connects to fluid channel three (602), fluid channel two (401) connects to fluid channel four (601), and air guide hole one (402) connects to air guide hole two (603). The sealing ring (3) is installed in the sealing ring groove of valve sleeve one (2) and valve sleeve two (4), and cooperates with valve body (6) and valve core (1) to isolate different fluid channels. The connection between air guide hole one (402) and air guide hole two (603) can conduct the spring cavity to the atmosphere, eliminating the influence of the change of air pressure in the spring cavity on the movement of valve core (1) during the movement.

[0023] The working principle of this utility model is as follows:

[0024] like Figure 2 As shown, this is the first working position of the valve core (1), where the valve core (1) is in the closed state. Under the action of the spring force, the sealing surface one (102) and the sealing surface two (202) abut to form a sealing structure. At this time, the fluid entering from the fluid channel four (601) of the valve body (6) through the fluid channel two (401) of the valve sleeve two (4) will be cut off and cannot flow to the fluid channel one (201) of the valve sleeve one (2).

[0025] like Figure 3As shown, this is the second working position of the valve core (1), in which the valve core (1) is in the connected state. When an external driving force is applied to the valve core (1), it overcomes the spring force and causes the valve core (1) to move. The guide groove (101) of the valve core (1) connects the first fluid channel (201) and the second fluid channel (401), thereby establishing a fluid passage.

[0026] When the external driving force disappears, the valve core (1) is reset under the action of the spring force, so that the valve core (1) returns from the second working position to the first working position, completing the conversion of the fluid passage from connection to cut-off.

[0027] In practical applications, a two-position two-way valve structure can be configured with one or more units to meet actual functional requirements. Multiple configurations better demonstrate the advantages of this example in terms of compact structure, convenient operation, and high reliability.

[0028] In summary, this novel two-position two-way valve structure not only optimizes the product structure and reduces the size of the equipment, but also improves the system reliability, ease of operation, and flexibility. It has broad application prospects, will inject new vitality into the development of fluid control technology, and is expected to play an important role in various industrial designs.

[0029] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
