Referring to fig. 1, 2 and 5, in one embodiment, a connecting valve 100 comprises: the valve body 110, the first connecting member 120, the second connecting member 130 and the control assembly 140 are connected. The connecting valve body 110 is provided with a first flow passage 111 and a second flow passage 112, and the connecting valve body 110 is used for being connected with a water supply pipe. The first connecting piece 120 is installed on the connecting valve body 110, and the first connecting piece 120 and the connecting valve body 110 form an included angle, the first connecting piece 120 is used for being connected with the water inlet end of the wall-mounted boiler, the first connecting piece 120 is provided with a third flow passage 121, and the third flow passage 121 is communicated with the second flow passage 112. The second connecting piece 130 is installed on the connecting valve body 110, the second connecting piece 130 is used for being connected with the filter bowl 200, and the second connecting piece 130 is provided with a fourth flow passage 131 and a fifth flow passage 132. The fifth flow passage 132 communicates with the third flow passage 121. The control assembly 140 is disposed on the connecting valve body 110, and the control assembly 140 is used for controlling whether the second flow channel 112 and the fourth flow channel 131 are respectively communicated with the first flow channel 111.
The connecting valve 100 comprises a connecting valve body 110, a first connecting piece 120, a second connecting piece 130 and a control assembly 140, wherein the first connecting piece 120 and the second connecting piece 130 are arranged on the connecting valve body 110, and the first connecting piece 120 and the connecting valve body 110 form an included angle, so that the connecting valve 100 can be used for conveniently arranging a pre-filter on a wall-mounted furnace and a water supply pipe. In addition, the connecting valve body 110 is provided with a first flow passage 111 and a second flow passage 112, the first connecting piece 120 is provided with a third flow passage 121, the third flow passage 121 is communicated with the second flow passage 112, the second connecting piece 130 is provided with a fourth flow passage 131 and a fifth flow passage 132, and the fifth flow passage 132 is communicated with the third flow passage 121, so that water in the fifth flow passage 132 can flow into the third flow passage 121; the control assembly 140 is mounted on the connecting valve body 110, and the control assembly 140 can control whether the second flow passage 112 and the fourth flow passage 131 are respectively communicated with the first flow passage 111. As can be seen, in operation, the control unit 140 connects the first flow channel 111 to the fourth flow channel 131, and the first flow channel 111 and the second flow channel 112 are disconnected, so that water flows into the fourth flow channel 131 from the first flow channel 111, and the water flowing into the fourth flow channel 131 is filtered by the filter bowl 200 due to the second connecting member 130, and flows out of the fifth flow channel 132, and the filtered water finally flows out of the third flow channel 121 and further flows into the wall-hanging stove due to the fifth flow channel 132 being connected to the third flow channel 121. Thus, by installing the connection valve 100 on the wall-hanging stove and the water supply pipe, water can be conveniently controlled to enter the filter bowl 200 for filtering.
Alternatively, the first connector 120 and the connecting valve body 110 may be angled according to the angle between the wall hanging stove and the water supply pipe.
Specifically, the first connector 120 is at right angles to the connecting valve body 110. Therefore, the wall-mounted boiler, the pre-filter and the water supply pipe are more reasonable in overall structural arrangement, and the overall effect of the pre-filter is improved.
In one embodiment, the connecting valve body 110 is designed as a tube with one end closed; the first connecting piece 120 is designed as a pipe with two communicated ends; the second connecting member 130 is configured to cover the filter bowl 200, so that the second connecting member 130 is more tightly matched with the filter bowl 200, thereby effectively preventing water from seeping between the second connecting member 130 and the filter bowl 200 during the process of flowing into the filter bowl 200. Referring to fig. 1, the end cover is connected to the connecting valve body 110, two through holes are formed in the end cover, and an opening is also formed in the connecting valve body 100, so that the end cover is communicated with the connecting valve body 100 through the through holes and the opening.
Further, the inner diameter of the fourth flow channel 131 increases from the end of the second connecting member 130 near the connecting valve body 110 to the end of the second connecting member 130 far from the connecting valve body 110. Thus, the flow rate of water into the filter bowl 200 can be slowed, and the purpose is firstly to slow down the impact of water on the filter bowl 200; 2. the residence time of the water in the filter bowl 200 is increased so that the water is adequately filtered. Specifically, referring to fig. 2, the fourth flow channel 131 of the present embodiment is divided into a first flow channel section 1311, a second flow channel section 1312, and a third flow channel section 1313, wherein the inner diameter of the third flow channel section 1313 is larger than the inner diameter of the second flow channel section 1312, and the inner diameter of the second flow channel section 1312 is larger than the inner diameter of the first flow channel section 1311. Meanwhile, in order to make the water smoothly flow, the present embodiment connects the inner side wall of the second flow path section 1312 and the inner side wall of the third flow path section 1313 in a smooth transition. In addition, in order to enable the filtered water to rapidly flow out of the fifth flow passage 132, the present embodiment also designs that the inner diameter of the first flow passage section 1311 is larger than the inner diameter of the fifth flow passage 132.
Still further, referring to fig. 3 and 4, the control assembly 140 includes a valve stem 141 and a valve core 142 that are interconnected. The valve spool 142 is fitted into the first flow passage 111. The connecting valve body 110 is provided with a first mounting hole 114. The valve stem 141 is coupled to the valve cartridge 142 through the first mounting hole 114, and the valve stem 141 is capable of driving the valve cartridge 142 to rotate within the first flow passage 111. When the valve rod 141 drives the valve core 142 to rotate, the valve core 142 can control whether the second flow passage 112 and the fourth flow passage 131 are respectively communicated with the first flow passage 111. Thus, by rotating the valve rod 141, the valve core 142 rotates in the first flow channel 111, so as to control the water in the first flow channel 111 to flow into the fourth flow channel 131, which is more beneficial to controlling the water to enter the filter bowl 200 for filtering.
In one embodiment, referring to fig. 4, 6, 8 and 9, a valve element 142 is provided with a sixth flow channel 1421, a seventh flow channel 1422 and an eighth flow channel 1424 which are mutually communicated, when the valve element 142 rotates to a first position, the fourth flow channel 131 is communicated with the first flow channel 111 through the sixth flow channel 1421 and the seventh flow channel 1422, and the second flow channel 112 is disconnected from the first flow channel 111; when the valve core 142 rotates to the second position, the second flow passage 112 is communicated with the first flow passage 111 through the sixth flow passage 1421 and the eighth flow passage 1424, and the fourth flow passage 131 is disconnected from the first flow passage 111; when the valve body 142 rotates to the third position, the second flow passage 112 and the fourth flow passage 131 are blocked from the first flow passage 111, respectively. As can be seen, the sixth flow channel 1421, the seventh flow channel 1422 and the eighth flow channel 1424 on the valve element 142 form a three-way structure, when the valve element 142 rotates to the first position, the connecting valve 100 is in a fully opened state, i.e. the sixth flow channel 1421 is communicated with the fourth flow channel 131, and the seventh flow channel 1422 is communicated with the first flow channel 111, i.e. the water flows from the first flow channel 111 into the fourth flow channel 131 through the valve element 142; when the spool 142 is rotated to the second position, the connecting valve 100 is in a bypass state, i.e., the sixth flow passage 1421 is in communication with the first flow passage 111, and the eighth flow passage 1424 is in communication with the third flow passage 111, i.e., water flows directly from the first flow passage 111 through the second flow passage 112 into the third flow passage 121 through the spool 142. When the valve body 142 is rotated to the third position, the connecting valve 100 is in a closed state, i.e., the second flow passage 112 and the fourth flow passage 131 are disconnected from the first flow passage 111, i.e., water cannot flow into the connecting valve 100 from the water supply pipe. Thus, the valve core 142 can satisfy the realization of various operations of the prefilter.
Further, the valve element 142 is located in the first flow channel 111, and the valve element 142 is located at one end of the fourth flow channel 131, so that the valve element 142 can accurately and rapidly control the communication states of the second flow channel 112 and the fourth flow channel 131 with the first flow channel 111 respectively.
In one embodiment, the spool 142 is further provided with a slot 1423. An insert 1411 is provided on the valve stem 141, and insertion of the valve stem 141 into the slot 1423 via the insert 1411 drives the valve core 142 to rotate within the first fluid passage 111. The control assembly 140 also includes a handle 143. The handle 143 is connected to the valve stem 141 such that the valve stem 141 can be easily rotated by the handle 143. The handle 143 is provided with more than one first limiting member 1431, and the second connecting member 130 is provided with a second limiting member 133. The first limiting member 1431 is in limiting engagement with the second limiting member 133. In this way, in the process of controlling the water flow direction, the rotation position of the handle 143 can be accurately controlled by the first limiting member 1431 and the second limiting member 133, so that the water flow direction can be accurately controlled.

In addition, in order to allow water of the fourth flow path 131 to completely flow into the filtering flow path 510, one end of the filtering member 500 of the present embodiment is closely attached to the second connection member 130.
Further, the pre-filter further comprises a magnetic element 600. A magnetic element 600 is positioned within the bowl cavity 210, the magnetic element 600 being used to remove rust from the water. Since the water flowing into the water supply pipe also contains a large amount of rust impurities, the rust in the water needs to be cleaned before the water flows into the fifth flow passage 132. Thus, when water flows into the filter bowl cavity 210, the magnetic member 600 will absorb rust in the water, so that the water flowing into the fifth flow channel 132 will be cleaner.
Specifically, the magnetic member 600 is a magnetic rod, one end of the magnetic rod is mounted on the inner sidewall of the filter bowl 200, and the other end of the magnetic rod extends along the direction towards the second connecting member 130, so that the contact surface between the magnetic rod and water is increased, which is beneficial to improving the adsorption capacity of the magnetic rod to rust.
