Abstract
The utility model relates to a vacuum air control delay water valve. A radial flow passing opening is arranged between an axial inlet and an axial outlet of a valve body, the radial end of the valve body is provided with an air cylinder, and the other end is provided with a valve rod channel; one end of a valve rod is connected with a piston, the other end passes through the valve rod channel and is connected with a reset spring and a valve cap, the middle part of the valve rod passes the flow passing opening to form a valve, a micro channel is arranged between the air cylinder and the piston, and an air cylinder cover is provided with control opening which is communicated with a vacuum air source. The utility model has the advantages that the structure is simple, the utility model is convenient to directly using in a water saving cleaning system such as a vacuum toilet, etc., the water flushing quantity can be conveniently adjusted, the overall system is simplified, and thereby, the cost is reduced.
Description
The utility model is a kind of valve of controlling liquid flow, can be used in the vacuum closet as Time-delay water valve.
Current, the delay flushing valve that is used for places such as washroom, lavatory is various in style, utility model patent as patent No. ZL94228986.2 discloses a kind of delay-self-closing flushing valve, the valve rod that can directly move the opening and closing valve is arranged, be connected with back-moving spring on the valve rod, cylinder is arranged on valve body, the piston that can move in cylinder is arranged on the valve rod, there is cylinder head the cylinder outer end, and non return valve for outflow and air inlet choke valve are arranged on the cylinder head.When this sharp flushing valve was used for vacuum closet, needing increased a lot of control device and plant equipment, has strengthened the complexity and the cost of system.Rarely seen in document both at home and abroad about the flushing valve that is directly used in vacuum closet, it is reported some occasion in addition with microprocessor to water flow controlling.
The Time-delay water valve that the purpose of this utility model is to provide occasion such as a kind of vacuum closet to use can satisfy water-saving function, and enough scouring forces are provided again, simplifies the whole system structure, thereby reduces cost.
Realize the vacuum gas control Time-delay water valve of the utility model purpose, constitute by valve body, valve rod, back-moving spring, valve body is a cavity body, the axial end of cavity body is that import, the other end are to have between outlet, import and the outlet radially to cross head piece, cavity body radially towards both sides projection, side projection constitute cylinder, the offside projection constitutes valve stem passage, valve rod one end connects that piston, the other end in the described cylinder passes valve stem passage, the valve rod middle part was passed head piece and constituted valve; It is characterized in that: (1) valve stem passage is built-in with back-moving spring, the valve stem passage outer end is with bonnet, and valve rod passes back-moving spring and connects with bonnet; (2) there is cylinder head described cylinder outer end, has control mouthful on the cylinder head, is used for being communicated with vacuum source by control assembly; (3) have small runner on the described cylinder wall.
Described vacuum gas control Time-delay water valve, it is further characterized in that on the described piston and is equipped with sealing ring, is equipped with sealing ring between described back-moving spring bottom valve rod and the valve stem passage.
Described vacuum gas control Time-delay water valve can also be equipped with stop screw on described bonnet and/or described valve stem passage external surface is equipped with stop nut.
The utility model is simple in structure, is convenient to be directly used in water saving such as the vacuum closet cleaning systems, and each discharging quantity of water can arbitrarily be adjusted, and adjusting range is 0.25~0.8 liter/time.
Fig. 1 closes the station generalized section for the utility model.
Fig. 2 opens the station generalized section for the utility model.
Fig. 3 is for using vacuum closet example of the present utility model.
Among Fig. 1, vacuum gas control Time-delay water valve import 33 connects running water pipe, the device that drenches with rain is removed in outlet 26, cross valve 27 shutoffs of head piece 25 by valve rod 23 middle parts, valve rod 23 1 ends connect the piston 28 in the cylinder 29, and the other end passes back-moving spring 22 and valve stem passage 24 and connects with bonnet 21, has control mouth 30 on the cylinder head, be used for being communicated with vacuum source, have small runner 31 on the cylinder wall by control assembly.When needing bath, control mouth 30 is connected with vacuum source, water and air in the cylinder 29 is sucked away, piston 28 also is subjected to negative-pressure sucking, driving valve 27 descends, back-moving spring 22 is compressed into the unlatching station state of Fig. 2, has the tap water of pressure to be able to pour into the device flushing toilet bowl that drenches with rain from import 33, mistake head piece 25, outlet 26.The utility model time-delay principle is: control mouthful 30 shutoff vacuum source passages, tap water enters cylinder 29 from the small runner 31 on the piston 28 next door cylinder walls, back-moving spring 22 is promoted valve 27 and is risen gradually, progressively overcomes residual vacuum negative pressure in the cylinder 29, crosses head piece 25 time-delay closings.
The stop nut 32b of stop screw 32a on the bonnet 21 and/or valve stem passage 24 external surfaces plays the effect that limits piston 28 dropping distances, thereby can adjust the time length of deferred action.
Fig. 3 represents that the utility model is used for the situation of vacuum closet system, this system is made up of vacuum energy storage canister 1, reversal valve 2, vacuum gas control Time-delay water valve 3, the device 4 that drenches with rain, closet 5, interface valve 6, vaccum stop valve 7, one way valve 8 and each unicom pipeline, and the import of vacuum gas control Time-delay water valve 3 is joined with water supply pipe with the city by hand switch 9.
During work, the user presses the button of reversal valve 2, and the control mouth 30 of vacuum gas control Time-delay water valve 3 is connected with vacuum source by reversal valve 2, vacuum energy storage canister 1, one way valve 8, vaccum stop valve 7, crosses head piece 25 and crosses water.After the user discharged the button of reversal valve 2, reversal valve 2 turn-offed the control mouth 30 of vacuum gas control Time-delay water valve 3 and the passage of vacuum source, and vacuum gas control Time-delay water valve 3 time delayed turn-offs are crossed head piece.
