Description

Technical Field

[0001] The utility model relates to the technical field of multi-way valves, and more specifically, to a multifunctional valve. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. The valve allows the medium in pipes and equipment to flow or stop and can control its flow. The valve is a control component in a fluid delivery system.

[0003] In applications, four-way valves are often needed. The existing four-way valves are usually cross-shaped, and the four fluid inlets and outlets (referred to as valve ports) on the same plane are connected to four fluid pipelines respectively. The valve core of the four-way valve usually has two fluid passages that are not connected to each other. These two fluid passages are on the same plane and are connected to the four valve ports respectively. The four-way valve can control the conduction of four fluid pipelines at the same time and control the flow direction of the fluid medium in the pipelines. The use of four-way valves saves the use of two-way valves and reduces the manufacturing cost of process pipelines.

[0004] However, the four fluid inlets and outlets (referred to as valve ports) of the existing four-way valve are all on the same plane, which is a planar conduction. As a result, the existing four-way valve can only conduct fluid pipelines adjacent to each other, while the two opposite pipelines cannot be conducted, resulting in the problem of a single usage of the four-way valve in the prior art.

[0040] A multifunctional valve of the present application is described in detail through the following embodiments.

[0041] In this embodiment, if Figures 1 to 8 As shown, the multifunctional valve comprises: an outer shell 1, an inner shell 2, an adjusting member 3, a first handle 4 and a second handle 5; the outer shell 1 is provided with a first inner cavity 105 and a first opening 101, a second opening 102, a third opening 103 and a fourth opening 104 respectively connected with the first inner cavity 105, and the first opening 101, the second opening 102, the third opening 103 and the fourth opening 104 are all used for external pipes;

[0042] The inner shell 2 is rotatably disposed in the first inner cavity 105, and the outer side wall of the inner shell 2 is sealed with the side wall of the first inner cavity 105. The inner shell 2 is used to block one of the first opening 101, the second opening 102, the third opening 103 and the fourth opening 104. The inner shell 2 is provided with a second inner cavity 204 and a fifth opening 201, a sixth opening 202 and a seventh opening 203 respectively communicated with the second inner cavity 204. The fifth opening 201, the sixth opening 202 and the seventh opening 203 are respectively used to communicate with one of the first opening 101, the second opening 102, the third opening 103 and the fourth opening 104;

[0043] The adjusting member 3 is rotatably disposed in the second inner cavity 204, and the adjusting member 3 and the second inner cavity 204 are sealed, and the adjusting member 3 is used to adjust the communication state among the fifth opening 201, the sixth opening 202 and the seventh opening 203;

[0044] The first handle 4 passes through the outer shell 1 and is fixedly connected to the inner shell 2 , and is used to drive the inner shell 2 to rotate. The second handle 5 passes through the inner shell 2 and the outer shell 1 and is connected to the adjustment member 3 , and is used to drive the adjustment member 3 to rotate.

[0045] Furthermore, the first opening 101 and the second opening 102 are respectively arranged on the first pair of side surfaces of the outer shell 1, the third opening 103 and the fourth opening 104 are respectively arranged on the second pair of side surfaces of the outer shell 1, the first handle 4 and the second handle 5 are respectively located on the third pair of side surfaces of the outer shell 1, and the directions in which the first pair of side surfaces, the second pair of side surfaces and the third pair of side surfaces are located are arranged perpendicular to each other.

[0046] In the present technical solution, the first pair of side surfaces are the upper and lower side surfaces of the outer shell 1, the second pair of side surfaces are the front and rear side surfaces of the outer shell 1, and the third pair of side surfaces are the left and right side surfaces of the outer shell 1. The first opening 101 is arranged on the upper side of the outer shell 1, the second opening 102 is arranged on the lower side of the outer shell 1, the third opening 103 is arranged on the front side of the outer shell 1, and the fourth opening 104 is arranged on the rear side of the outer shell 1. The first inner cavity 105 is located at the intersection of the four openings, and the first inner cavity 105 is arranged as a spherical surface as a whole. The first opening 101 to the fourth opening 104 are all circular hole-shaped structures extending from the outside to the inside, and are all connected to the first inner cavity 105. The inner shell 2 is arranged as a hollow part with the left and right side surfaces being planes and the front and rear upper and lower side surfaces being a spherical surface. The hollow part of the inner shell 2 forms the aforementioned second inner cavity 204, and the outer side surface of the second inner cavity 204 is arranged as a spherical surface equal to the first inner cavity 105, and the inner side surface of the second inner cavity 204 is arranged as a plane. In the initial state, the fifth opening 201 to the seventh opening 203 are circular hole structures respectively arranged on the lower side, the front side and the rear side of the inner shell 2, and the fifth opening 201 at this time makes the second opening 102 communicate with the second inner cavity 204, the sixth opening 202 makes the third opening 103 communicate with the second inner cavity 204, and the seventh opening 203 makes the fourth opening 104 communicate with the second inner cavity 204. At this time, the upper side of the inner shell 2 blocks the first opening 101, so that the first opening 101 and the second inner cavity 204 are not connected.

[0047] The adjusting member 3 is a plate-like structure. In the initial state, the adjusting member 3 is horizontally arranged. At this time, the upper and lower side surfaces of the adjusting member 3 are two planes, and the front and rear side surfaces are spherical surfaces adapted to the second inner cavity 204. The left and right side surfaces are arranged to be planar in order to respectively connect the first handle 4 and the second handle 5, which is also convenient for abutting against the left and right side surfaces of the inner shell 2.

[0048] The left side of the outer shell 1 is provided with a through hole for passing the first handle 4 , and the first handle 4 is fixedly connected to the left side of the inner shell 2 through the through hole. The inner shell 2 can be driven to rotate by rotating the first handle 4 .

[0049] The right side surface of the outer shell 1 and the right side surface of the inner shell 2 are each provided with another through hole for passing the second handle 5. The second handle 5 is fixedly or detachably connected to the right side surface of the adjustment member 3 through the through hole, and the adjustment member 3 can be driven to rotate by the second handle 5.

[0050] When in use, for the sake of convenience, the positions of the inner shell 2, the outer shell 1 and the adjusting member 3 in the above initial state are used for description: in the initial state, the first opening 101 is blocked by the inner shell 2, the second opening 102 to the fourth opening 104 are connected to the second inner cavity 204, and the adjusting member 3 is horizontally placed in the second inner cavity 204. At this time, the adjusting member 3 divides the second inner cavity 204 into two parts, the upper and lower parts, but at this time, the second opening 102 to the fourth opening 104 are in a state of mutual communication; the adjusting member 3 is rotated clockwise by forty-five degrees, and at this time, the adjusting member 3 is The third opening 103 on the front side is blocked, leaving only the second opening 102 and the fourth opening 104 connected; continue to rotate the adjusting member 3 clockwise forty-five degrees, the adjusting member 3 reaches a vertical state, and the second opening 102 to the fourth opening 104 are again connected to each other; then rotate the adjusting member 3 clockwise forty-five degrees again, at which time the adjusting member 3 blocks the fourth opening 104 on the rear side, leaving only the second opening 102 and the third opening 103 connected; then rotate the adjusting member 3 forty-five degrees again, and the adjusting member 3 reaches a horizontal state again.

[0051] The above only describes the process of the adjustment member 3 rotating. The following will fix the adjustment member 3 and rotate the inner shell 2 to illustrate: in the initial state, the adjustment member 3 is horizontally arranged, and the inner shell 2 blocks the first opening 101; the inner shell 2 is rotated forty-five degrees, at which time the first opening 101 is opened, and the area directly connected between the first opening 101 and the third opening 103 is blocked by the inner shell 2 and the adjustment member 3, but at this time the first opening 101 is connected to the fourth opening 104, the fourth opening 104 is connected to the second opening 102, and the second opening 102 is connected to the third opening 103, so that the first opening 101 and the third opening 103 are connected. The state of indirect connection is reached, and then the four openings are in a connected state; the inner shell 2 is continued to be rotated forty-five degrees, and the third opening 103 is blocked by the inner shell 2. At this time, the first opening 101, the second opening 102 and the fourth opening 104 are in a connected state; the inner shell 2 is rotated forty-five degrees again; the state of all four openings being opened is reached again, but the third opening 103 and the second opening 102 are connected to the first opening 101 through the fourth opening 104; thereafter, the inner shell 2 is rotated forty-five degrees again, the second opening 102 is blocked by the inner shell 2, and the other three openings are in a connected state.

[0052] It can be seen from the above process that by simultaneously controlling the positions of the inner shell 2 and the adjustment member 3 , any two openings or any three openings from the first opening 101 to the fourth opening 104 can be connected, or all four openings can be controlled to be connected.

[0055] In the present technical solution, the first locking member 6 is a bolt, and a threaded hole facing the first handle 4 is provided on the left side of the outer shell 1, and the first locking member 6 is adapted to the threaded hole. When in use, the first locking member 6 is screwed so that the inner end surface of the first locking member 6 abuts against the side surface of the first handle 4, thereby achieving a locking effect on the first handle 4 and preventing the first handle 4 from rotating after adjustment. The second locking member (not shown in the figure) has the same structure as the first locking member 6, and is fixed to one side of the second handle 5 through another threaded hole on the right side of the outer shell 1, and is used to lock the second handle 5.

[0056] In this embodiment, a supporting ear 301 is provided on the side of the adjusting member 3 , and the supporting ear 301 abuts against the side wall of the second inner cavity 204 , and the supporting ear 301 is used to support the adjusting member 3 .

[0057] In the technical solution, in the initial state, the support ear 301 is a C-shaped reinforcing rib structure respectively fixed to the upper and lower sides of the adjusting member 3, and the upper and lower sides of the support ear 301 are spherical surfaces of the same size as the second inner cavity 204, so as to form support for both sides of the adjusting member 3. Since the adjusting member 3 is directly impacted by the internal water flow during use, the support ear 301 can improve the structural strength and extend the service life.

[0058] In some technical solutions, through holes are provided on the supporting ear 301 and the main body of the adjusting member 3, and the supporting ear 301 is fixed to the adjusting member 3 by bolts, so as to facilitate installation, disassembly and replacement.

[0059] In this embodiment, the adjusting member 3 is provided with a groove, and the second handle 5 is provided with a protrusion matched with the groove.
