Abstract
The utility model relates to a valve, particularly an automatic water inlet valve, which comprises a valve seat 2, and a valve stem 1 which is sheathed in the valve seat, wherein, the end part of the valve stem is fixedly provided with an adjusting pad 7; a pressure adjusting spring 3 is arranged between the valve seat and the valve stem adjusting pad; the valve stem is provided with a water inlet hole 8 capable of communicating with a water outlet hole 9 which is arranged at the other end of the valve stem; the rear of the water inlet hole which is arranged on the valve stem is provided with a sealing gasket 4 for matching with the valve seat. The utility model has the advantages of simple structure, convenient operation, water saving, time saving, trouble saving, etc.
Description
The utility model relates to a kind of valve, particularly a kind of automatic water inlet valve.
Existing various valve is by formations such as valve body, valve seats, though can realize unidirectional water inlet, but its structure is complicated, and can not realize automatic water inlet, especially during water tank water intake such as train, passenger vehicle, need the staff connect water pipe, and then drive valve, close valve, take off water pipe etc., both wasted water, time-consuming again bothersome.
The purpose of this utility model is exactly a kind of simple in structure, easy to use, automatic water inlet valve of economizing on water, saving time and saving trouble of design.
The purpose of this utility model realizes by following structure: a kind of automatic water inlet valve, it is characterized in that: it includes valve seat and is enclosed within the interior valve rod of valve seat, the intrinsic spacer in valve rod end, between valve seat and valve rod spacer, pressure adjusting spring is arranged, there is the water inlet to communicate on the valve rod, the sealing gasket that cooperates with valve seat is arranged behind water inlet on the valve rod with the osculum of the valve rod the other end.When using the utility model, this valve is packed in the delivery hose, with pipe collar be locked this valve base and delivery hose, only need during water inlet the intake pipe of outlet pipe and water tank is pegged graft, intake pipe and spring acting in conjunction are offset hydraulic pressure and are backed down valve rod, and water enters water tank from the water inlet by osculum, after water tank water is full, dial lower discharging tube, this valve pushes against spring and promotes valve rod and move under hydraulic action, closes the valve water inlet and realizes closing automatically.
The utility model compared with prior art has simple in structure, uses advantages such as more convenient, especially when being used for train, the water filling of passenger vehicle water tank, not only having saved time and has saved trouble but also economize on water.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. valve rod, 2. valve seat, 3. pressure adjusting spring, 4. sealing gasket, 5. plain cushion, 6. nut, 7. spacer, 8. water inlet, 9. osculum.
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1: the utility model includes valve seat 2 and is enclosed within the interior valve rod 1 of valve seat, the intrinsic spacer 7 in valve rod end, between valve seat and valve rod spacer, pressure adjusting spring 3 is arranged, there is water inlet 8 to communicate on the valve rod, the sealing gasket 4 that cooperates with valve seat is arranged behind water inlet on the valve rod with the osculum 9 of the valve rod the other end; For easy to use, regulate the axial pressure of filling up according to different hydraulic pressure, spacer and valve rod screwed connection, in like manner the valve rod osculum is tapered, when water tank water is filled, because tapered, a part of hydraulic action is at the end face of tank inlet pipe, in this power and water tank under the back pressure effect of water, the intake pipe of outlet pipe and water tank breaks away from, then automatic water inlet valve overcomes the pressure adjusting spring restoring force under the effect of hydraulic pressure, closes automatic water inlet valve automatically.
Claims (3)
1. automatic water inlet valve, it is characterized in that: it includes valve seat (2) and is enclosed within the interior valve rod (1) of valve seat, the intrinsic spacer in valve rod end (7), pressure adjusting spring (3) is arranged between valve seat and valve rod spacer, there is water inlet (8) to communicate on the valve rod, the sealing gasket (4) that cooperates with valve seat is arranged behind water inlet on the valve rod with the osculum (9) of the valve rod the other end.
