Abstract
The utility model discloses a four-way single-switch washing machine valve, which is aiming at solving the defect of easy abrasion of existing sealing loop. The utility model comprises a pipeline, a valve and a manual switch. On the pipeline is provided with a water inlet, a water outlet and a valve positioning unit. The valve comprises a valve base, a valve cover, a valve rod, and a lifting device. The valve base and the valve cover are connected as an empty chamber. The lifting device is arranged inside the empty chamber. The lifting device is set as U-shaped with the inner surface packed with a screw. The valve rod runs through the valve cover and rotates corresponding to the valve cover. Top end of the valve rod is connected with the manual switch and the outer surface of the bottom end of the valve cover is provided with a screw which is matching with the screw on the inner surface inside the lifting device. The valve base is connected with the lifting devices and the connection between the valve base and the lifting device is provided with a spring. A sealing ring is arranged on the bottom of the valve base. Because the inner radium fixed inside the valve is larger than that of the pipeline; the adoption of the down-press fastening sealing ring, the service life of the sealing ring has been greatly enhanced.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of four-way list switch washing machine valve.
Background technique
The washing machine valve is often to use in the daily life, and particularly automatic washing machine must be connected the water inlet of washing machine with water supply pipe.But because pipeline is prefabricated when all being building,, just must use the washing machine valves that lead to more, an existing water supply pipe is told many paths, Here it is multichannel washing machine valve if reserve special water supply pipe for washing machine.The most rotation check valve that adopt of existing washing machine valve, promptly being provided with one in the pipeline can be with respect to the valve of pipeline rotation, and this valve is provided with seal ring, realizes liquid sealing when the closure to guarantee valve.But, this existing valve all be by rotation compressing the effect that seal ring reaches sealing, so long-term use seal ring can be frequent and the pipeline friction, causes seal ring very easily to wear and tear, and causes the sealing effect reduction, the working life of valve is very low.
The model utility content
At defective that exists in the prior art and deficiency, the purpose of this utility model is to propose the four-way list switch washing machine valve that increase a kind of working life.
In order to achieve the above object, the utility model proposes a kind of four-way list switch washing machine valve, comprising: pipeline, valve, hand switch, described pipeline are provided with water inlet, water outlet, valve fixing part; Wherein, described valve comprises: valve seat, valve gap, valve rod, lowering or hoisting gear, and described valve gap and described pipeline are affixed; Described valve seat and valve gap socket also form a cavity; Described lowering or hoisting gear is located in the described cavity, and described lowering or hoisting gear is the U font, and internal surface has screw thread; Described valve rod runs through valve gap, and can described relatively valve gap does and rotate in a circumferential direction; And described valve stem tip is fixedlyed connected with hand switch, and the valve gap bottom outer surface is provided with screw thread, and the screw thread of this screw thread and described lowering or hoisting gear internal surface is suitable; Described valve seat and described lowering or hoisting gear socket, and valve seat and lowering or hoisting gear joint are provided with spring; Described valve seat bottom is provided with seal ring; The internal diameter of described valve fixing part is greater than described internal diameter of the pipeline.
Wherein, described valve gap is provided with limit stoper, to prevent valve rod when rotation slippage.
Wherein, described pipeline is a four-way pipeline, comprises a water inlet and two water outlets, and a valve fixing part, and when valve closes, at least one water outlet and pipeline are isolated.
Wherein, be provided with the O RunddichtringO between described valve gap outer surface and the pipeline, to guarantee the sealing of valve and described pipeline gas.
Wherein, be provided with the O RunddichtringO between described valve rod and the valve body.
Wherein, be provided with pad between described valve rod and the valve gap.
Wherein, be provided with the O RunddichtringO between lowering or hoisting gear and the valve gap.
The four-way list switch washing machine valve that the utility model proposes, when the user rotated hand switch, hand switch drove the valve rod rotation.Owing to be connected with lowering or hoisting gear by screw thread in the valve rod, therefore when valve rod rotates, can drive the lowering or hoisting gear generation and move axially.When lowering or hoisting gear descends because the compressing valve body of spring moves down, when spring pressure during greater than hydraulic pressure valve body be depressed, the internal diameter of valve fixing part is greater than internal diameter of the pipeline simultaneously, and valve body bottom is provided with seal ring, makes that valve body can closed conduit, and a water outlet and pipeline are completely cut off.Simultaneously,,, make the direct roof pressure valve body of stem bottom, can reach the function of closed conduit if when acting force of the spring causes promoting valve body and moves less than hydraulic pressure when pressing down, only need to continue rotary valve rod because valve body is U type structure.After having adopted said structure, seal ring can not rub with pipeline during throttle down, has prolonged the working life of seal ring, the working life of yet having improved the washing machine valve simultaneously.
Description of drawings
Fig. 1 is a four-way list switch washing machine valve sectional view of the present utility model;
Fig. 2 is the valve sectional view of four-way list switch washing machine valve of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model preferred embodiment comprises a pipeline 22 and a valve 21, and described pipeline 22 is provided with water inlet, water outlet, valve fixing part, pipeline is an inverted T shape, bottom left is a water intake 23, and the right side is second water outlet 29, and the top is first water outlet 28.When valve closing at ordinary times, valve body presses down and makes first water outlet 28 isolated with pipeline 22, when using washing machine, only need open valve first water outlet 28 is communicated with pipeline 22.
As shown in Figure 2, valve comprises valve rod 1, valve gap 5, valve seat 11, and wherein valve gap 5 is affixed with pipeline 21; Valve seat 11 is with valve gap 5 sockets and form a cavity; Described lowering or hoisting gear 8 is located in the described cavity, and lowering or hoisting gear 8 is the U font, and internal surface has screw thread; Valve rod 1 runs through valve gap 5, and valve gap 5 is done and rotated in a circumferential direction relatively; And fixedly connected with hand switch in valve rod 1 top, and valve gap 5 bottom outer surface are provided with screw thread, and the screw thread of this screw thread and described lowering or hoisting gear internal surface is suitable; Valve seat 11 and lowering or hoisting gear 8 sockets, and valve seat 11 is provided with spring 9 with lowering or hoisting gear 8 joints; Described valve seat bottom is provided with seal ring 10; The internal diameter of described valve fixing part is greater than described internal diameter of the pipeline.
As preferably,, be provided with one at valve gap 5 tops with jump ring 2 in order to prevent valve gap slippage when rotated.
