DETAILED DESCRIPTION
[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0030] Reference Figure 1-9 As shown,
[0031] A bypass valve comprises a valve body 1, an opening and closing assembly 2 arranged on the valve body 1, the opening and closing assembly 2 switches the water path of the valve body 1, the valve body 1 is provided with a first passage 3 and a second passage 4, the opening and closing assembly 2 is located between the first passage 3 and the second passage 4, the two ends of the first passage 3 are respectively a water inlet 11 and a control valve water inlet interface 12, and the two ends of the second passage 4 are respectively a water outlet 13 and a control valve water outlet interface 14; the water inlet 11 and the water outlet 13 are located on the same side of the valve body 1, and the control valve water inlet interface 12 and the control valve water outlet interface 14 are located on the other side of the valve body 1;
[0032] Switching of opening and closing component 2
[0033] The water inlet 11 is connected to the control valve water inlet interface 12 and the water outlet 13 is connected to the control valve water outlet interface 14, or
[0034] The water inlet 11 is connected to the water outlet 13 and the control valve water inlet interface 12 is connected to the control valve water outlet interface 14 .
[0035] In this solution, the first passage 3 and the second passage 4 formed by the combination of the valve body 1 and the opening and closing component 2 are normal passages, which are respectively used to connect the water inlet 11 with the water inlet interface 12 of the control valve, and to connect the water outlet 13 with the water outlet interface 14 of the control valve. When the bypass pipeline is needed, the opening and closing component 2 is used to switch so that the bypass pipeline can be involved. In this solution, only one opening and closing component 2 is needed to switch the first passage 3 and the second passage 4 on the valve body 1, and there is no need to use multiple two-way valves or three-way valves to achieve it, which can reduce costs. At the same time, it is more convenient to connect with the pipeline, and only one opening and closing component 2 needs to be operated when in use.
[0036] In the specific structure, the opening and closing assembly 2 includes a switch component 21 and a driving component 22, and the driving component 22 drives the switch component 21 to switch the passage. The switch component 21 includes a fixed valve plate 211 and a movable valve member 212. The fixed valve plate 211 is circumferentially fixed in the valve body 1, and the movable valve member 212 is linked with the driving component 22 and rotated by the driving component 22; the fixed valve plate 211 is provided with a first through hole 2111, a second through hole 2112, and a third through hole 2113, the first through hole 2111 is connected to the control valve water inlet interface 12, the second through hole 2112 is connected to the control valve water outlet interface 14, and the third through hole 2113 is connected to the water outlet 13; the movable valve member 212 is provided with a first channel 2121 and a second channel 2122; the first channel 2121 is connected to the water inlet 11 (the rotation of the first channel 2121 is used to switch the water inlet 11 to cooperate with the corresponding through hole to achieve passage switching);
[0037] The movable valve member 212 switches by rotating
[0038] The first channel 2121 cooperates with the first through hole 2111 to communicate with the control valve water inlet interface 12 and the water inlet 11, and the second channel 2122 cooperates with the second through hole 2112 and the third through hole 2113 to communicate with the control valve water outlet interface 14 and the water outlet 13 (refer to Figure 3 as shown); or,
[0039] The first channel 2121 cooperates with the third through hole 2113 to communicate with the water inlet 11 and the water outlet 13, and the second channel 2122 cooperates with the first through hole 2111 and the second through hole 2112 to communicate with the control valve water inlet interface 12 and the control valve water outlet interface 14 (refer to Figure 5 as shown).
[0040] The movable valve member 212 in the above structure can be an integrated structure, referring to Figure 3 As shown, the entire movable valve member 212 is made of ceramic material and is connected to the driving member 22 through the shift fork 8. Figure 3 In the structure shown in , the entire movable valve member 212 is made of ceramic material and can be matched with the fixed valve plate 211. The movable valve member 212 and the shift fork 8 can be matched in a circumferential rotation manner by using a keyway, so that the shift fork 8 can drive the movable valve member 212 to rotate circumferentially.
[0041] The driving component 22 can be an electric mechanism or a manual mechanism, such as a motor drive or a handle rotation.
[0042] First of all, it should be noted that the fixed valve plate 211 is circumferentially fixed in the valve body 1, that is, the fixed valve plate 211 will not rotate circumferentially, so the state of the through hole on the fixed valve plate 211 is also relatively stable.
[0043] When the switch component 21 switches the path, the specific process is as follows:
[0044] Based on whether the bypass is involved, it can be divided into the following two states:
[0045] 1. Normal passage state: the water inlet 11 is connected to the control valve water inlet interface 12, and the water outlet 13 is connected to the control valve water outlet interface 14. The first through hole 2111 of the fixed valve plate 211 is connected to the control valve water inlet interface 12, the second through hole 2112 is connected to the control valve water outlet interface 14, and the third through hole 2113 is connected to the water outlet 13. At this time, the first channel 2121 of the movable valve member 212 is connected to the first through hole 2111 and the water inlet 11; the second channel 2122 is connected to the first through hole 2111 and the second through hole 2112. That is, the first channel 2121 on the movable valve member 212 is connected to the first through hole 2111, and the water at the water inlet 11 first passes through the first channel 2121 and enters the control valve water inlet interface 12 through the first through hole 2111; at the same time, the water at the control valve water outlet interface 14 first passes through the second through hole 2112 and enters the second channel 2122, enters the third through hole 2113 through the second channel 2122, and then enters the water outlet 13.
[0046] The above-mentioned water flow direction is only used as one of the usages, and the same can be applied by reversing the water flow direction.
[0047] 2. Bypass intervention state: that is, the water inlet 11 is connected to the water outlet 13, and the control valve water inlet interface 12 is connected to the control valve water outlet interface 14. The first through hole 2111 of the fixed valve plate 211 is connected to the control valve water inlet interface 12, the second through hole 2112 is connected to the control valve water outlet interface 14, and the third through hole 2113 is connected to the water outlet 13. At this time, after the movable valve member 212 rotates, the first channel 2121 is in a state of matching with the third through hole 2113, and the second through hole 2112 is in a state of matching with the first through hole 2111 and the second through hole 2112. That is, water from the water inlet 11 enters the third through hole 2113 after passing through the first channel 2121, and enters the water outlet 13 through the third through hole 2113; at the same time, water from the control valve water outlet interface 14 first enters the second channel 2122 through the second through hole 2112, and enters the first through hole 2111 from the second channel 2122, and then flows to the control valve water inlet interface 12.
[0048] Similarly, the above-mentioned water flow direction is only one of the flow directions, and it can also be used in the reverse direction. At the same time, after the water from the water inlet 11 flows out of the water outlet 13, there may be no water flowing between the control valve water outlet interface 14 and the control valve water inlet interface 12. Of course, the same is true in reverse (the control valve water outlet interface 14 and the control valve water inlet interface 12 are connected with water, and there is no water in the water inlet 11 and the water outlet 13).
[0049] In the above-mentioned implementation scheme, in order to facilitate the cooperation between the movable valve member 212 and the fixed valve plate 211, the following implementation method can be selected: the first through hole 2111, the second through hole 2112, and the third through hole 2113 are evenly distributed along the circumference on the fixed valve plate 211, and the first channel 2121 on the movable valve member 212 is adapted to the first through hole 2111, and the second channel 2122 is also adapted to the combination of the second through hole 2112 and the third through hole 2113.
[0050] The three through holes are evenly distributed in three equal parts, that is, refer to Figure 1 , 4 , 8 , and 9 , each through hole is located in the middle of a 120° block.
[0051] The above-mentioned through-hole distribution enables the first channel 2121 and the second channel 2122 to maintain a stable matching state when switching the corresponding states with the through-holes when the movable valve member 212 rotates. Otherwise, the size of the through-holes needs to be reduced to allow the first channel 2121 and the second channel 2122 to adapt to each through-hole, which will reduce the water volume.
[0052] It should be supplemented that when the movable valve member 212 cooperates with the fixed valve plate 211, the two need to fit tightly together to maintain a seal and avoid cross-talk.
[0053] Preferably, the side surface of the first channel 2121 is a hollow surface (see Figure 7 As shown) or formed by the concave side of the movable valve member 212 (refer to Figure 6 As shown); the second channel 2122 is a blind hole arranged on the movable valve member 212.
[0054] Since the first channel 2121 needs to allow the water in the first through hole 2111 to flow to the outside through the water inlet 11, the side of the first channel 2121 needs to have at least a hollow surface to allow water to flow out from the side. Of course, a concave portion can also be directly formed by concave, and the first through hole 2111 is directly connected to the outside by using the concave portion, so that water can directly enter the water inlet 11 from the first through hole 2111. The second channel 2122 is set as a blind hole in order to maintain the passage between the two through holes, and the outside is in a sealed state, so setting it as a blind hole can make the passage sealing effect better.
[0055] In order to make the sealing effect better, refer to Figure 1 As shown, an abutment sheet 5 is provided on the end of the movable valve member 212 corresponding to the fixed valve plate 211. The fixed valve plate 211 and the abutment sheet 5 abut against each other and are used to cooperate to form a seal. The movable valve member 212 is connected to the first through hole 2111, the second through hole 2112, and the third through hole 2113 through the abutment sheet 5.
[0056] The abutment sheet 5 and the fixed valve sheet 211 can be abutted with ceramic sheets, and the hard seal between the two ceramic sheets is used to achieve abutment sealing, thereby making the passage more stable and preventing cross-talk. In this solution, the movable valve member 212 and the abutment sheet 5 are separately arranged. In this solution, the movable valve member 212 can be made of plastic material, and the abutment sheet 5 is made of ceramic material. At this time, it can ensure the sealing cooperation with the fixed valve sheet 211 while reducing the cost. Since the movable valve member 212 can be made of plastic material, it can be directly integrated with the shift fork 8, and the production is also convenient.
[0057] Specifically, a plurality of positioning grooves 6 are provided on the side of the abutment sheet 5 along the circumferential direction, and positioning members 7 are provided at positions corresponding to the positioning grooves 6 on the movable valve member 212. When the movable valve member 212 is assembled with the abutment sheet 5, the positioning members 7 are inserted into the positioning grooves 6 to form circumferential synchronous rotation.
[0058] The coordination mode of the structure can make the structure simpler and easier to install, while having a circumferential linkage effect.
[0059] In further supplementation, it should be noted that good sealing is required at positions such as the shift fork 8 and the fixed valve plate 211, for example, by using sealing rings or sealing gaskets. Those skilled in the art are well aware that when the valve is switching passages, it is necessary to avoid water flow cross-talk and to maintain the sealing state between the various components, so no further elaboration will be given here.
[0060] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
