Description
Technical field
The present invention is more particularly directed to a kind of delay switch and its working principles.
Background technique
Flushing valve is widely used in the water-closet of family or public place, structure include valve body, float valve and
Drive the switch of float valve movement.Currently, one is simple and mechanical drivings, and one is electromagnetism there are mainly two types of switches on the market
Driving.
The patent of invention of simple and mechanical driving, the Publication No. CN2033412U as disclosed on 2 25th, 1988 discloses
A kind of hand presses, pedal double-purpose water-saving flushing valve, it includes valve body, float valve and compression bar, and high pressure chest and low pressure chamber, pressure are equipped in valve body
When bar is first state, the sealing ring on compression bar side wall blocks high pressure chest and low pressure chamber, switches to the second state by moulded rod, high
Pressure chamber is connected to low pressure chamber, and further, float valve moves under the action of pressure at both sides difference, completes primary bath.However it is such
Structure, compression bar are necessarily mounted on valve body as actuator, and directly contact valve intracorporal water is easy when pressing, more unhygienic, together
When, compression bar comes since the needs of pressing must expose outside, so that the installation of flushing valve has been more limited.
Electromagnetic drive, also known as solenoid valve, it is divided into Direct Action Type, distribution Direct Action Type and pilot-operated type.Wherein, direct-acting electromagnetic valve
Coil including valve body, float valve and driving float valve movement, valve body is interior to be equipped with intake tunnel, water flushing channel, and float valve is the first shape
When state, the opening of water flushing channel to be blocked in the effect of spring force, and the second state is switched to after energization, coil generates magnetic field,
Overcome the elastic force of spring to pick up float valve, open water flushing channel, completes primary bath.But such structure, the material of float valve
It needs to be the ferrimagnet that can be picked up, and the intracorporal medium of valve body material, valve also there are certain requirements.
To sum up, need to develop it is a kind of installation, the better simply driving switch of material requirements.

Water route is unimpeded until the gas bleeder valve 200 exhaust terminates.
Embodiment two
It refers to the difference shown in Fig. 7 and Fig. 8, with embodiment one to be: further including gas storage air bag 500, the gas is defeated
Song Guan 400 separates the first, second, third branch after by the check valve 410, and the first branch connects the control air bag
130, second branch connects the gas bleeder valve 200, and third branch connects the gas storage air bag 500.
Its working principle is that: the control air bag 130 also connects the gas storage air bag 500, and the gas generator 300 is simultaneously to this
Control air bag 130 and the gas storage air bag 500 are supplied；The gas outlet of the gas generator 300 connects the gas transmission pipeline
400, which is arranged check valve 410 in the middle, and the gas transmission pipeline 400 is after by the check valve 410
It separates three branches and is separately connected the gas storage air bag 500, the air bag processed of control 130 and the gas bleeder valve 200, which increases
The stability of the delay switch air-flow is added.
Embodiment three
Shown in Figure 9, the difference with embodiment two is: the gas of three-port structure being arranged in the second branch
Reversal valve 600,600 3 interfaces of the gas commutating valve respectively with the gas generator 300, the gas bleeder valve 200, the check valve
410 docking.When the interface docked with the gas generator 300 is opened, the interface docked with the gas bleeder valve 200 is closed, conversely, with
When the interface of the gas generator 300 docking is closed, the interface docked with the gas bleeder valve 200 is then opened.
Its working principle is that: the interface docked when the gas commutating valve 600 is inflated with the gas bleeder valve 200 is closed, and is inflated
Journey gas will not be exhausted from gas bleeder valve 200, and gas fully enters control air bag 130 and gas storage air bag 500.When the gas commutating valve
600 stop inflating the interface closing docked afterwards with the gas commutating valve 600, control the gas in air bag 130 and gas storage air bag 500
It is vented again from gas bleeder valve 200.
The gas commutating valve 600 can prevent gas during inflating from exhausting from the gas bleeder valve 200, only inflate knot
After beam, the interface docked with the gas bleeder valve 200 is just opened, in this way, the control air bag 130 and the gas storage air bag can be extended
The total time of gas exhaust in 500, to extend the time of draining.
The above is only the preferred embodiment of the present invention, the range implemented of the present invention that therefore, it cannot be limited according to, i.e., according to
Equivalent changes and modifications made by the invention patent range and description, should still be within the scope of the present invention.
