Description

Technical Field

[0001] This utility model relates to the field of fluid valve technology, and in particular to a five-way valve. Background Technology

[0002] A flow control valve is a key component used to control the switching or distribution of fluid between multiple channels. It is widely used in many fields such as HVAC, water treatment, industrial process control, medical devices, and irrigation. Existing flow control valves typically employ a design with stationary and moving plates working together. By overlapping the stationary and moving plates and making mirror-sealed contact, they rotate in opposite directions, connecting the different through holes on the stationary and moving plates to open and close each water passage and control the water flow rate in each passage.

[0003] In many scenarios, multi-way valves need to simultaneously regulate multiple passages. Currently, some multi-way valves employ an inner and outer valve body structure. The inner valve body has two sets of flow channels. Water first enters the outer valve body, and then the two sets of flow channels enter through the upper and lower end faces of the inner valve body, respectively. Regulation is achieved through two sets of static and dynamic plates, which improves the control flexibility of the multi-way valve. However, after water enters the outer valve body, it needs to flow vertically within the outer valve body to enter different flow channels from the upper and lower ends of the inner valve body. This results in a significant reduction in the flow velocity of the water after entering the valve body, causing a decrease in the outlet pressure of the multi-way valve and severely weakening its remote delivery performance. Utility Model Content

[0004] In view of this, the present invention proposes a five-way valve to solve the problem that water needs to flow up and down inside the outer valve body after entering the valve body so that it can enter different flow channels from the upper and lower ends of the inner valve body, resulting in a significant reduction in water flow velocity.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a five-way valve, including a valve shell, which is hollow inside; an inner cylinder, which is disposed inside the valve shell; and four water outlet pipes, which are disposed on the valve shell. The cross-sectional shape of the valve shell is elliptical or rectangular, and the vertical direction of the cross-section of the valve shell is the axial direction of the valve shell and the inner cylinder. The two axial end faces of the inner cylinder are spaced apart from the interior of the valve shell, and the two axial end faces of the inner cylinder are open. The interior of the inner cylinder is connected to the interior of the valve shell through the open surfaces. The maximum inner diameter of the inner cylinder is smaller than the minimum outer diameter of the valve shell. One end of the water outlet pipe is connected to the outer peripheral wall of the inner cylinder and is connected to the interior of the inner cylinder. The other end of the water outlet pipe extends outward through the valve shell. A channel is provided between the portions of adjacent water outlet pipes located inside the valve shell.

[0006] Based on the above technical solutions, preferably, the four water outlet pipes located inside the valve body are arranged in an X-shape or a cross shape, forming four channels between the four water outlet pipes. Two channels are located at both ends of the long axis of the valve body cross-section, and the other two channels are located at both ends of the short axis of the valve body cross-section.

[0007] Even more preferably, the four water outlet pipes are simultaneously arranged in a mirror-symmetrical manner with respect to the major and minor axes of the valve body cross-section.

[0008] Even more preferably, all four outlet pipes extend along the short axis of the valve housing cross-section.

[0009] Based on the above technical solutions, preferably, the inner cylinder has two first cavities and two second cavities. The two first cavities pass through one end face of the inner cylinder and are connected to the inside of the valve shell. The two second cavities pass through the other end face of the inner cylinder and are connected to the inside of the valve shell. The water outlet pipe is connected to the end of the outer peripheral wall of the inner cylinder and is connected to the first or second cavity.

[0010] More preferably, notches are provided on the outer peripheral walls at both ends of the inner cylinder along the axial direction. The two notches face the two ends of the long axis of the valve shell cross-section, and the two notches face away from the first cavity and the second cavity, respectively.

[0011] More preferably, the two first cavities are arranged symmetrically with respect to the long axis of the valve housing cross-section, and the two second cavities are also arranged symmetrically with respect to the long axis of the valve housing cross-section.

[0012] More preferably, it also includes two valve plate assemblies, which are respectively disposed on the two end faces of the inner cylinder; wherein, one valve plate assembly is disposed between the two first cavities and the inside of the valve housing, and the other valve plate assembly is disposed between the two second cavities and the inside of the valve housing, and the valve plate assembly is used to adjust the communication cross-sectional area between the first cavity or the second cavity and the inside of the valve housing.

[0013] Based on the above technical solutions, preferably, the valve shell includes a housing with both axial ends through it; a cover and a seat, which are respectively covered on both axial ends of the housing and form a valve shell with the housing; wherein, an inner cylinder is provided inside the housing, and the two end faces of the inner cylinder are respectively spaced apart from the inner walls of the cover and the seat; four water outlet pipes are connected to the housing, and the channels are set inside the housing.

[0014] A further preferred embodiment includes a water inlet pipe connected to the cover or seat; wherein the water inlet pipe is connected to the inside of the valve housing.

[0015] The five-way valve of this utility model has the following advantages over the prior art: (1) The present invention designs the outer valve shell as a long rectangle or ellipse, so that there is a larger flow space between the valve shell and the inner cylinder, so that water can flow up and down through multiple channels formed between multiple outlet pipes after entering the valve shell, which can avoid weakening the inlet flow rate and flow volume, and ensure that the water pressure at the far end of the five-way valve outlet passage remains high.

[0016] (2) By opening notches on the outer peripheral sidewalls at both ends of the inner cylinder, the internal space of the valve body is further increased, so that the water entering the valve body has a larger range of movement and the dead zone inside the valve body is eliminated, so that small impurities will not accumulate in large quantities in certain blind areas of the valve body and cause blockage, and can maintain a large water flow rate entering the valve body to flush away impurities, thereby avoiding the risk of blockage and stalling of the passage valve.

[0017] (3) The valve shell of this utility model is designed to be an integral structure formed by the upper and lower covers and the seat covering the upper and lower ends of the shell, which facilitates the assembly and maintenance of the internal structure of the valve shell.

[0027] like Figure 1 As shown, combined with Figure 2 , Figure 3 and Figure 4This utility model discloses a five-way valve, comprising a valve body 1, an inner cylinder 2, and a water outlet pipe 3. The valve body 1, the inner cylinder 2, and the water outlet pipe 3 can be made of metal, plastic, or ceramic materials.

[0028] The valve housing 1 is hollow inside, and its cross-sectional shape is elliptical or rectangular. The vertical direction of the cross-section of the valve housing 1 is the axial direction of the valve housing 1 and the inner cylinder 2. The cross-sectional shape of the valve housing 1 has a major axis A and a minor axis B, which makes the valve housing 1 form a laterally expanded structure, and the interior of the valve housing 1 is wider than that of a traditional circular valve body.

[0029] The inner cylinder 2 is installed inside the valve body 1. Both axial end faces of the inner cylinder 2 are spaced apart from the interior of the valve body 1. The function of the inner cylinder 2 is to connect with the water outlet passage for water separation. Both axial end faces of the inner cylinder 2 are open, and the interior of the inner cylinder 2 is connected to the interior of the valve body 1 through the open surfaces. Water can flow into different water outlet passages from the upper and lower ends of the inner cylinder 2. Therefore, by adjusting the flow area at the upper and lower ends of the inner cylinder 2, the flow control of multiple water outlet passages can be more flexible. The maximum inner diameter of the inner cylinder 2 is smaller than the minimum outer diameter of the valve body 1, so that there is a large flow space between the inner cylinder 2 and the valve body 1. After the water enters the valve body 1, it can maintain a high flow velocity and a large flow rate in the valve body 1 and flow up and down, and enter different passages from the upper and lower ends of the inner cylinder 2 respectively.

[0030] Four water outlet pipes 3 are installed on the valve body 1. The outer ends of different water outlet pipes 3 are connected to different output pipes. One end of the water outlet pipe 3 is connected to the outer peripheral wall of the inner cylinder 2 and is connected to the inside of the inner cylinder 2. The other end of the water outlet pipe 3 extends outward through the valve body 1. A channel 101 is provided between the parts of adjacent water outlet pipes 3 located inside the valve body 1. After water enters the valve body 1, it can maintain a high flow rate and a large flow volume in the valve body 1 through the channel 101 to flow up and down, so that the far end of the output pipe connected to the water outlet pipe 3 maintains a high water pressure and a large water flow rate.

[0031] exist Figure 2 In one embodiment shown, the four water outlet pipes 3 are arranged in an X-shape or cross shape within the valve housing 1, forming four channels 101. Two channels 101 are located at both ends of the long axis A of the valve housing 1's cross-section, and the other two channels 101 are located at both ends of the short axis B of the valve housing 1's cross-section. The large number of channels 101 provides a larger and more sufficient flow space between the inner cylinder 2 and the valve housing 1, avoiding weakening the water flow velocity when the water flows up and down. At the same time, it allows water to pass through more channels 101 when flowing upwards, maintaining a large flow rate for the upward-flowing water.

[0032] exist Figure 3In one embodiment shown, the four water outlet pipes 3 are simultaneously arranged in a mirror-symmetrical manner with respect to the major axis A and minor axis B of the cross-section of the valve body 1, so that the internal structure of the valve body 1 is symmetrical, ensuring the balance of the water flow between the upper and lower parts, and facilitating mass production of the product.

[0033] exist Figure 3 In one embodiment shown, all four outlet pipes 3 extend along the short axis B of the cross-section of the valve body 1, so that the extension direction of the outlet pipes 3 is perpendicular to the widening direction of the valve body 1, thereby preventing the overall width of the five-way valve from increasing further and making the overall length-to-width ratio of the five-way valve more balanced, which is beneficial for mass production, storage and transportation of the product.

[0034] exist Figure 6 In one embodiment shown, the inner cylinder 2 has two first cavities 201 and two second cavities 202. Both first cavities 201 pass through one end face of the inner cylinder 2 and communicate with the interior of the valve housing 1. Both second cavities 202 pass through the other end face of the inner cylinder 2 and communicate with the interior of the valve housing 1. The water outlet pipe 3 is connected to the end of the outer peripheral wall of the inner cylinder 2 and communicates with either the first cavity 201 or the second cavity 202. The inner cylinder 2 has a total of four water outlet pipes 3, thus this five-way valve has four water outlet passages. Since the four water outlet passages respectively enter water through the upper and lower end faces of the inner cylinder 2, the flow area at the upper and lower ends of the inner cylinder 2 can be adjusted to more flexibly control the flow of multiple water outlet passages.

[0035] exist Figure 2 In one embodiment shown, notches 203 are provided on the outer peripheral walls at both axial ends of the inner cylinder 2. The two notches 203 face the two ends of the long axis A of the valve housing 1 cross-section, and are respectively opposite to the first cavity 201 and the second cavity 202. Normally, the outer side of the notch 203 position of the inner cylinder 2 is enclosed, making the end face of the inner cylinder 2 a complete circle. However, this design creates a blind zone or dead zone at the notch 203 position. When impurities are present in the water, they may remain in this blind zone or dead zone after entering the valve housing 1. If the impurities accumulate continuously or are large, they can cause blockage or stalling within the five-way valve. Therefore, in this embodiment, by creating the notch 203, the dead zone or blind zone at the end face of the inner cylinder 2 is eliminated. This not only further increases the internal space of the valve housing 1 but also allows for the flushing away of impurities entering the notch 203 position by a larger water flow and flow rate, thereby preventing impurities from remaining in the valve housing 1 and causing blockage or stalling.

[0036] exist Figure 3In one embodiment shown, the two first cavities 201 are symmetrically arranged with respect to the major axis A of the cross-section of the valve housing 1, and the two second cavities 202 are also symmetrically arranged with respect to the major axis A of the cross-section of the valve housing 1, so that the internal structure of the inner cylinder 2 is symmetrical, ensuring the balance of water output through the upper and lower end faces of the inner cylinder 2, and facilitating mass production of the product.

[0037] exist Figure 5 In one embodiment shown, a valve plate assembly 5 is further included. Two valve plate assemblies 5 are respectively disposed on two end faces of the inner cylinder 2; one valve plate assembly 5 is disposed between the two first cavities 201 and the interior of the valve housing 1, and the other valve plate assembly 5 is disposed between the two second cavities 202 and the interior of the valve housing 1. The valve plate assembly 5 is used to adjust the communication cross-sectional area between the first cavity 201 or the second cavity 202 and the interior of the valve housing 1. The valve plate assembly 5 can be a combination of a single stationary plate and a single moving plate, or a combination of a single stationary plate and multiple moving plates.

[0038] exist Figure 1 In one embodiment shown, the valve housing 1 includes a housing 11 with its two axial ends extending through it; a cover 12 and a seat 13 are respectively installed on the two axial ends of the housing 11 and together with the housing 11 to form the valve housing 1; wherein, an inner cylinder 2 is provided inside the housing 11, and the two end faces of the inner cylinder 2 are respectively spaced apart from the inner walls of the cover 12 and the seat 13; four water outlet pipes 3 are connected to the housing 11, and a channel 101 is provided inside the housing 11. This design of the valve housing 1, with the upper and lower covers 12 and the seat 13 covering the upper and lower ends of the housing 11 to form an integral structure, facilitates the assembly and maintenance of the internal structure of the valve housing 1.

[0039] exist Figure 1 In one embodiment shown, a water inlet pipe 4 is also included. The water inlet pipe 4 is connected to the cover 12 or the seat 13; the water inlet pipe 4 is connected to the interior of the valve housing 1. The five-way valve in this embodiment is a vertical valve.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
