Description

Technical Field

[0001] The utility model relates to a three-way valve, in particular to a multi-directional regulating three-way valve used in the valve field. Background Art

[0002] A three-way valve is a valve device with three ports, one inlet and two outlets. According to the fluid action mode, the three-way valve is divided into a combining valve and a diverting valve. The combining valve has two inlets and flows out from one outlet after merging. The diverting valve has one fluid inlet and flows out from two fluid outlets after diversion.

[0003] The specification of Chinese patent CN213745053U discloses a hydraulic three-way valve. A second abutting sealing structure is provided between the valve core and the second channel of the utility model. When the valve core and the first channel are abutted and sealed, the second channel and the third channel are connected. When the valve core and the second channel are abutted and sealed, the first channel and the third channel are connected. The utility model has a reasonable and simple structural design, high structural stability, good sealing, not easy to leak, and easy assembly, which solves the problem that the existing hydraulic three-way valve is prone to loose closure and leakage.

[0004] The above-mentioned three-way valve changes the direction of the fluid by means of a valve core abutting and sealing when in use. However, when in use, only one of the left and right joints can be connected, and the valve core will directly and completely seal the joint when sealing, so that the fluid in the joint can only flow out at a fixed flow rate, thereby reducing the practicality of the three-way valve. Utility Model Content

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that the existing three-way valve changes the direction of the fluid by means of a valve core abutting and sealing. When in use, only one of the left and right joints can be connected, and the flow rate of the fluid in the joint cannot be adjusted, so its practicality is low.

[0006] To solve the above problems, the utility model provides a multi-directional adjustable three-way valve, including a valve body, the left and right ends of the valve body are respectively threadedly connected with a left joint and a right joint, the lower end of the valve body is fixedly connected to the water inlet pipe, the front end of the valve body is rotatably penetrated by an adjusting shaft, the inner wall of the valve body is rotatably connected to the positioning shaft, the end corresponding to the adjusting shaft and the positioning shaft are fixedly connected to a mounting plate 1, the left ends of the two mounting plates 1 are jointly fixedly connected to a baffle 1, the outer surfaces of the adjusting shaft and the positioning shaft are movably sleeved with a mounting plate 2, the upper ends of the two mounting plates 2 are jointly fixedly connected to a baffle 2, the lower end of the front mounting plate 1 is fixedly connected to a push plate, and the left end of the front mounting plate 2 is chiseled with a slot corresponding to the push plate, the front end of the adjusting shaft is fixedly connected to an adjusting block, and the left joint, the right joint and the end of the water inlet pipe close to the valve body are all fixedly connected to a clamping ring.

[0007] In the above-mentioned multi-directional adjustable three-way valve, the structure is simple and easy to operate. Different joints are blocked by baffles one and two, thereby adjusting the flow direction of the fluid inside the three-way valve. At the same time, the flow rate of the three-way valve can be adjusted according to the degree of blocking, which effectively improves the practicality of the three-way valve.

[0008] As a further improvement of the present application, the valve body is spherical as a whole, and the end of the clamping ring close to the adjusting shaft is elastic.

[0009] As a further improvement of the present application, both baffle 1 and baffle 2 are spherical with cross-section processing, and the diameter of baffle 2 is larger than the diameter of baffle 1.

[0010] As another improvement of the present application, a sealing sleeve is rotatably sleeved on the outer surface of the adjusting shaft, and the rear end of the sealing sleeve is fixedly inserted into the valve body.

[0011] As another improved supplement of the present application, an adjusting sleeve is further provided between the adjusting shaft and the sealing sleeve. The adjusting sleeve is movable on the outer surface of the adjusting shaft, and the rear end of the adjusting sleeve is fixedly connected to the second mounting plate in the front.

[0012] To sum up, in actual application, by rotating the adjusting shaft, baffle one rotates around the adjusting shaft, and when the push plate fits into the slot, baffle one can drive baffle two to rotate, so that baffle one and baffle two block the left joint, the right joint and the water inlet pipe, thereby changing the direction of the fluid inside the valve body. At the same time, the flow rate of the fluid can be adjusted according to the different degrees of blocking of the left joint, the right joint and the water inlet pipe. The structure is simple and easy to operate, which is convenient for adjusting the flow direction of the fluid inside the three-way valve. At the same time, the flow rate of the three-way valve can be adjusted according to the degree of blocking, which effectively improves the practicality of the three-way valve.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1 and Figure 2 It shows: a multi-directional adjustable three-way valve, including a valve body 1, the left and right ends of the valve body 1 are respectively threadedly connected with a left joint 2 and a right joint 3, the lower end of the valve body 1 is fixedly connected with a water inlet pipe 4, the front end of the adjusting shaft 5 is fixedly connected with an adjusting block 13, the left joint 2, the right joint 3 and the end of the water inlet pipe 4 close to the valve body 1 are fixedly connected with a clamping ring 14, when the baffle 1 8 and the baffle 2 10 are fitted with different clamping rings 14, the left joint 2, the right joint 3 and the water inlet pipe 4 can be blocked, the valve body 1 is spherical as a whole, the end of the clamping ring 14 close to the adjusting shaft 5 is elastic, the baffle 1 8 and the baffle 2 10 have different inner diameters, and the elastic clamping ring 14 can make the baffle 1 8 and the baffle 2 10 both fit tightly with the clamping ring 14.

[0027] Figure 2 、 Figure 3 and Figure 4It is shown that: the front end of the valve body 1 rotates and penetrates the adjusting shaft 5, the inner wall of the valve body 1 is rotatably connected to the positioning shaft 6, the adjusting shaft 5 and the corresponding end of the positioning shaft 6 are fixedly connected to the mounting plate 1 7, the left ends of the two mounting plates 1 7 are commonly fixedly connected to the baffle 1 8, and the two mounting plates 1 7 can be driven to rotate by controlling the adjusting shaft 5. At this time, the baffle 1 8 and the positioning shaft 6 are both rotated, and the outer surfaces of the adjusting shaft 5 and the positioning shaft 6 are movably sleeved with a mounting plate 2 9, the upper ends of the two mounting plates 2 9 are commonly fixedly connected to the baffle 2 10, the lower end of the front mounting plate 1 7 is fixedly connected to the push plate 11, and the left end of the front mounting plate 2 9 is chiseled with a push plate The plate 11 corresponds to the card slot 12. After the control adjustment shaft 5 is rotated, the baffle 1 8 rotates to the bottom of the baffle 2 10. The push plate 11 is located inside the card slot 12. The adjustment shaft 5 continues to be rotated. The push plate 11 can push the mounting plate 2 9 to rotate, thereby rotating the bag baffle 2 10. Both baffle 1 8 and baffle 2 10 are spherical with cross-section processing. The diameter of baffle 2 10 is larger than the diameter of baffle 1 8, so that baffle 2 10 can be located above baffle 1 8. The outer surface of the adjusting shaft 5 is also rotatably sleeved with a sealing sleeve 15. The rear end of the sealing sleeve 15 is fixed and penetrates into the valve body 1. The sealing sleeve 15 can effectively improve the sealing performance of the valve body 1.

[0028] Figure 5 It is shown that: the baffle 8 is controlled to rotate by adjusting the shaft 5 so that the baffle 8 fits with the clamping ring 14 in the water inlet pipe 4, thereby blocking the water inlet pipe 4, so that the fluid cannot enter the interior of the valve body 1 through the water inlet pipe 4, and the three-way valve is in a closed state.

[0029] Figure 6 It is shown that: baffle 1 8 fits with the clamping ring 14 in the left joint 2, thereby shielding the left joint 2, and baffle 2 10 is located at the upper part of the inner cavity of the valve body 1. At this time, the three-way valve can realize water inlet from the bottom and water outlet from the right.

[0030] Figure 7 It is shown that the second baffle 10 fits with the clamping ring 14 in the right joint 3, thereby shielding the right joint 3, and the first baffle 8 is located at the upper part of the inner cavity of the valve body 1. At this time, the three-way valve can realize water inlet from the bottom and water outlet from the left.

[0031] Figure 8 It shows that: baffle 1 8 and baffle 2 10 are both located in the upper part of the inner cavity of the valve body 1, and baffle 1 8 is located below baffle 2 10. The left joint 2, the right joint 3 and the water inlet pipe 4 are not blocked. At this time, the three-way valve can realize water inlet from the bottom and water outlet from both the left and right sides.

[0032] When in use, the baffle 1 8 is rotated around the adjusting shaft 5 by rotating the adjusting shaft 5, and when the push plate 11 is in contact with the card slot 12, the baffle 1 8 can drive the baffle 2 10 to rotate, so that the baffle 1 8 and the baffle 2 10 block the left joint 2, the right joint 3 and the water inlet pipe 4, thereby changing the direction of the fluid inside the valve body 1. At the same time, the flow rate of the fluid can be adjusted according to the different degrees of blocking of the left joint 2, the right joint 3 and the water inlet pipe 4. The structure is simple and easy to operate, which is convenient for adjusting the flow direction of the fluid inside the three-way valve. At the same time, the flow rate of the three-way valve can be adjusted according to the degree of blocking, thereby effectively improving the practicality of the three-way valve.

[0033] Second implementation method:

[0034] This embodiment is based on the first embodiment, with the addition of an adjustment sleeve 16, and the rest of the parts remain the same as the first embodiment.

[0035] Figure 9 It is shown that an adjusting sleeve 16 is further provided between the adjusting shaft 5 and the sealing sleeve 15 . The adjusting sleeve 16 is movably sleeved on the outer surface of the adjusting shaft 5 , and the rear end of the adjusting sleeve 16 is fixedly connected to the front mounting plate 2 9 .

[0036] During use, when adjusting the baffle 2 10 separately, the baffle 2 10 can be adjusted by rotating the adjustment sleeve 16, and there is no need to adjust the baffle 2 10 again and then reset the baffle 1 8, thereby facilitating use by the staff.

[0037] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
