Detailed Description
The foregoing and other embodiments and advantages of the invention will be apparent from the following, more complete, description of the invention, taken in conjunction with the accompanying drawings. It will be apparent that the described embodiments are merely some, but not all, embodiments of the invention.
In one embodiment, as shown in fig. 1-3.
The water-saving valve provided by the embodiment comprises a valve body 1 and a valve seat 2 arranged on the valve body 1, wherein a valve rod 3 inserted into the valve body 1 is arranged in the valve seat 2 in a penetrating manner, two ends of the valve rod 3 are respectively connected with a valve handle 4 and a valve core 5, a side hole 6 is formed in one side of the valve seat 2, a side pipe 7 communicated with the side hole 6 is further arranged on one side of the valve seat 2, a first bevel gear 8 rotatably connected to the valve rod 3 and positioned at the side hole 6 is arranged in the valve seat 2, a friction plate 9 attached to the upper surface of the valve core 5 and synchronously rotated along with the first bevel gear 8 is arranged below the first bevel gear 8, a driving rod 10 is rotatably connected in the side pipe 7, the driving rod 10 is inserted into the valve seat 2, two ends of the driving rod 10 are respectively provided with a second bevel gear 11 and a winding seat 12 meshed with the first bevel gear 8, a pull rope 13 is wound on the winding seat 12, one end of the pull rope 13 is connected with a handle 14, and the side pipe 7 and the driving rod 10 are connected through a volute spring 15. Wherein the winding seat 12, the driving rod 10 and the second bevel gear 11 can be pulled to rotate in the forward direction relative to the side tube 7 by the handle 14, and the spiral spring 15 provides the winding seat 12, the driving rod 10 and the second bevel gear 11 to rotate in the reverse direction relative to the side tube 7.
In the present embodiment, thawing is achieved by taking the heat generation by operating the friction valve core 5 outside the valve body 1. Because the heat preservation layer can be sleeved outside the pipeline connected with the two ends of the valve body 1, quick thawing can be realized. However, if the valve core 5 in the valve body 1 in direct contact with water is not thawed in time, the water-saving valve is not normally used. The technical problem to be solved by the embodiment is how to enable the water-saving valve to be quickly thawed. The direct frictional heating within the valve body 1 may defrost more rapidly than when hot water is poured outside the valve body 1. Since the water is frozen due to the low outdoor air temperature, it is difficult to transfer heat to the valve element 5 through the valve body 1 because the hot water poured outside the valve body 1 freezes for a short time.
In this embodiment, the winding seat 12, the driving rod 10 and the second bevel gear 11 can be pulled by the handle 14 to rotate forward relative to the side tube 7, and the second bevel gear 11 engages the first bevel gear 8 to drive the first bevel gear 8 and the friction plate 9 to rotate forward relative to the valve rod 3. During this process the pull cord 13 is pulled out and the volute spring 15 is compressed and deformed. And the release handle 14 is provided with a winding seat 12, a driving rod 10 and a second bevel gear 11 by a volute spring 15 to reversely rotate relative to the side pipe 7, so that the first bevel gear 8 and the friction plate 9 are driven to reversely rotate relative to the valve rod 3. In the process, the scroll spring 15 is restored and the stay cord 13 is reeled by the reeling seat 12 again. The two forward and backward processes enable the friction plate 9 to rub the upper surface of the valve core 5 to generate heat, the friction plate 9 is required to rotate continuously and rapidly by utilizing the heat generation of the friction plate 9, and the driving mode that the handle 14 is pulled in a linear driving mode instead of the driving rod 10 is operated in a rotary driving mode is a driving mode which can continuously apply force and saves labor. Thawing is thus achieved by operating the friction valve core 5 outside the valve body 1 to generate heat.
In one embodiment, as shown in fig. 3.
The second bevel gear 11 of the water saving valve provided in this embodiment is a spiral bevel gear. In addition, a ball bearing ring 16 is arranged between the first bevel gear 8 and the friction plate 9, and a ring groove 17 into which the ball bearing ring 16 is embedded is formed in the valve seat 2.
In the present embodiment, the spiral bevel gear may be engaged with the first bevel gear 8, or the common bevel gear may be engaged with the first bevel gear 8. In the present embodiment, by providing the ball bearing ring 16 between the first bevel gear 8 and the friction plate 9, the ring groove 17 is provided on the valve seat 2, facilitating the rotation of the first bevel gear 8 relative to the valve seat 2, i.e. reducing the resistance between the first bevel gear 8 and the friction plate 9 and the valve seat 2.
In one embodiment, as shown in FIG. 1.
The valve handle 4 of the water-saving valve provided by the embodiment comprises a circular rotary table 41 and a plurality of connecting rods 42 uniformly distributed in the rotary table 41, and the connecting rods 42 are connected with the end part of the valve rod 3.
In this embodiment, the connection structure between the valve handle 4 and the valve rod 3 basically uses a conventional structure, that is, the valve handle 4 is rotated to drive the valve rod 3 to rotate, so as to control the valve core 5 to open or close the valve.
In one embodiment, as shown in FIG. 2.
The water-saving valve provided by the embodiment is characterized in that two ends of the valve body 1 are respectively provided with a water inlet port 18 and a water outlet port 19. Furthermore, the inner diameters of the water inlet 18 and the water outlet 19 are smaller than the inner diameter of the valve body 1.
In the present embodiment, the water inlet 18 and the water outlet 19 are provided at both ends of the valve body 1 for water inlet and water outlet, respectively. The pipe diameters of the water inlet port 18 and the water outlet port 19 are made small because of the water saving requirement, especially the water saving valve.
In one embodiment, as shown in fig. 2-3.
The water-saving valve provided by the embodiment is characterized in that the winding seat 12 is cylindrical, an annular winding groove 20 taking the axis of the winding seat 12 as the center is formed in the circumferential surface of the winding seat 12, and the pull rope 13 is coiled in the winding groove 20.
In the present embodiment, the pulling cord 13 is wound in the winding groove 20 of the winding seat 12, so that it can be pulled out when in use and wound when not in use.
In one embodiment, as shown in fig. 2-3.
The water-saving valve provided by the embodiment is characterized in that a first limiting disc 21 is arranged on the end face of a side tube 7, the inner end of a scroll spring 15 is connected with a driving rod 10, the outer end of the scroll spring 15 is connected with the end face of the side tube 7, the scroll spring 15 is close to the first limiting disc 21, a second limiting disc 22 opposite to the first limiting disc 21 is arranged on the driving rod 10, and the second limiting disc 22 is close to the scroll spring 15. Wherein the first and second limit disks 21 and 22 limit the axial deformation space of the scroll spring 15.
In the present embodiment, the space for axial deformation of the scroll spring 15 is restricted by the first stopper disk 21 provided on the end surface of the side pipe 7 and the second stopper disk 22 provided on the drive rod 10. The scroll spring 15 is prevented from being deformed in the axial space, so that the driving force which can be generated by the scroll spring 15 is reduced, and the rotation speed of the friction plate 9 is reduced, thereby affecting the effect of friction heat generation. Therefore, the technical problem to be solved by the technical scheme provided by the embodiment is how to defrost more quickly.
In one embodiment, as shown in fig. 3.
In the water-saving valve provided in this embodiment, one side of the winding seat 12 is provided with the accommodating opening 23, and the first limiting disc 21 and the second limiting disc 22 are located in the accommodating opening 23.
