Summary of the invention
The purpose of this utility model be for solve the bathroom water tank run into when automatically water inlet and inlet valve use in some areas hydraulic pressure lower, can not prevent the former thereby abnormal problem of generation use such as siphon, a kind of reasonable in design is provided, utilizes the function of floating ball lever formula piston principle and one-way valve to reach automatic water inlet, moisturizing, prevent the inlet valve of siphon purpose.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: this inlet valve, comprise keg float, keg float guide rod, water inlet valve body, it is characterized in that being provided with one-way valve in the described water inlet valve body, be connected by rotating button bit between keg float guide rod and the water inlet valve body, the lower end of keg float guide rod is provided with sliding bar, one end of the top connection lever of sliding bar, the other end of lever is connected with connecting rod, and upper end one side of water inlet valve body is provided with water-adding pipe.
During water inlet, keg float makes progress gradually, water tank water intake, and water-adding pipe inserts drain valve and enters the ceramic bowl system, and to replenish the water yield of water seal effect in the ceramic bowl system, keg float is intercepted water intake to desired location sliding bar water sealing slice and is stopped into water, and one-way valve prevents siphon.
As preferably, a side of described connecting rod and keg float is fixed, and connecting rod is the screw type structure, and keg float is provided with nut.Connecting rod is as the up-down adjustment mechanism of keg float, and is adjustable up and down, or linkage structures such as buckle, latch mode.
As preferably, the lower end of described sliding bar is provided with the sliding bar water sealing slice, and sliding bar is arranged on the below of keg float guide rod.Connecting rod, lever, sliding bar constitute a kind of leverage, moved up and down by the buoyancy of keg float in water and deadweight drivening rod, and connecting rod interlock lever drives the sliding bar action up and down.
As preferably, described sliding bar and lever adopt and are slidingly connected, and lever is provided with articulating point, and the bearing pin in the articulating point is fixed on the matrix of keg float guide rod.The place of being slidingly connected can adopt globular hinge, reduces wear to reduce friction.
As preferably, the bottom of described water inlet valve body is provided with the intake pipe interface.The inlet valve body is used for being connected with water supply pipe.The intake pipe interface can adopt the structure of various ways.
Effective effect of the present utility model is: be that product structure used floating ball lever formula piston principle instead, simplified product structure, reduced product weight greatly, optimized the utilization ratio of plastics resources, reduce cost, reduced the wasting of resources, made product whole brief beautiful simultaneously.Increase an easy anti-backflow device, can effectively reach anti-siphonage, and simple installation.
Therefore, the utility model is a kind of reasonable in design, and is easy for installation, and the linkage mechanism knee-action is flexible, has the inlet valve of automatic water inlet, automatic water supplement plumbing valve, anti-siphon.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model Fig. 1.
Among the figure: 1. keg float, 2. connecting rod, 3. lever, 4. sliding bar water sealing slice, 5. one-way valve, 51. main body water shutoff mouths, 6. water-adding pipe, 7. keg float guide rod, 8. sliding bar, 9. water inlet valve body.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, present embodiment adopts plastics system bowl-type keg float 1, the main body of keg float 1 is positioned on the keg float guide rod 7, one avris of keg float is adorned the connecting rod 2 of a "T"-shaped screw type, the lower end of connecting rod 2 and lever 3 adopt the rotation collar that slides to fix, connecting rod 2 can be rotated, also can drive lever 3 and move up and down, to regulate the upper-lower position of keg float 1.
The other end of lever 3 is connected with the sliding bar 8 that is contained in keg float guide rod 7 belows, and establishes articulating point on lever 3 and keg float guide rod 7 matrixes, and sliding bar 8 belows are provided with the sliding bar water sealing slice 4 of a rubber system.
Keg float guide rod 7 matrixes below links into an integrated entity by rotation button bit and water inlet valve body 9, is one-way valve 5 in the water inlet valve body 9, and sliding bar water sealing slice 4 can move up and down along with sliding bar 8, fits with the main body water shutoff mouth 51 of water inlet valve body 9.There is the intake pipe interface bottom of water inlet valve body 9, and upper end one side of overflow pipe 10 is established a joint, is used for connecing water-adding pipe 6, and water-adding pipe 6 usefulness flexible pipes are made.
During the water inlet state, keg float 1 is at subsidence position, keg float interlock connecting rod 2 and lever 3 drive sliding bar water sealing slice 4 and raise up, water enters from the intake pipe interface, pass one-way valve 5, enter from the main body water shutoff mouth of opening 51 in the cavity of water valve body 9 into, in the cavity of water inlet valve body 9, flow out again, enter water tank.
Under the water shutoff state, the water level in the water tank constantly rises, and keg float 1 floats gradually, driving sliding bar water sealing slice 4 by connecting rod 2 and lever 3 simultaneously in floating-upward process presses down, up to propping up main body water shutoff mouth 51 tightly, water can not be passed through from main body water shutoff mouth 51, realize the water shutoff function.Because the design of one-way valve 5, the water in the water tank can't enter running water system by one-way valve 5.
Under the siphon state, because the design of one-way valve 5, the water in the water tank can't enter running water system by one-way valve 5.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any structure after the simple transformation of the present utility model is all belonged to protection domain of the present utility model.
