Specific embodiment
With reference to Fig. 1-3, the invention will be further described.
A kind of control system for excrement collector system with Slide value fault detection function, including guiding valve 10, guiding valve 10 wraps
Include slide valve 11 and cylinder 12, the cavity of cylinder 12 inner carrier side pass through two-position-five-way solenoid valve 20 respectively with electromagnetic valve 30,
Pressure switch 40 is connected, and the cavity of cylinder 12 inner carrier opposite side passes through two-position-five-way solenoid valve 20 and vacuum dirt box 50 phase
Even, the both sides of slide valve 11 connect with vacuum dirt box 50, closet 60 respectively, and slide valve 11 opens up air pressure test mouth 111, pressure
Power switch 40 is tested mouth 111 with air pressure and is connected.
The Cleaning Principle of the system is as follows:
1st, dead electricity after two-position-five-way solenoid valve 20 accepts during flush signal, for the ease of description, by two-position-five-way solenoid valve
20 mouth is labeled according to 1-5 described in accompanying drawing 1, and vacuum dirt box 50 passes through 1-2 mouth and the cylinder of two-position-five-way solenoid valve 20
12 connections, 5 mouthfuls of connection electromagnetic valves 30 of two-position-five-way solenoid valve 20, because electromagnetic valve 30 is to cut out, cylinder 12 can not be to the right
Motion, the interface of pressure switch 40 can form negative pressure simultaneously, is postponing some time (the demand adjustment setting controlling according to system
Time delay) electromagnetic valve 30 must be electric afterwards, and the piston of cylinder 12 promotes the valve block in guiding valve 10 to move right, and guiding valve 10 is open shape
State, as described in Figure 3, the dirt of closet 60 is arranged to vacuum dirt box 50 in the presence of negative pressure of vacuum.
Before and after electromagnetic valve 30 energized action, the pressure of the interface of pressure switch 40 can change, thus leading to pressure switch 40
Contact action output switching signal, if guiding valve 10 fault leads to the piston of cylinder 12 can not move, electromagnetic valve 30 obtains electric beating
After opening, the air pressure of the interface of pressure switch 40 does not have significant change, and control system does not receive pressure switch at the appointed time
The switching signal of output produces fault it can be determined that haveing guiding valve 10.
2nd, closet 60 is before blowdown process terminates, first electromagnetic valve 30 dead electricity and close.Blowdown process terminates, two-position five-way
Electromagnetic valve 20 first electric, vacuum dirt box 50 is connected with the cylinder 12 of guiding valve 10 by 1,4 mouthfuls of two-position-five-way solenoid valve 20,
Cylinder 12 promotes the valve plate movement of guiding valve 10 to close guiding valve 10 to the left, as shown in Fig. 2 subsequent electromagnetic valve 30 dead electricity is closed, one
Individual flushing pollution discharge process terminates.
3rd, before accepting next flush signal, the interface of pressure switch 40 is atmospheric pressure, guiding valve 10 and vacuum dirt
Case 50 connector is negative pressure state, if guiding valve 10 inner seal ring has leakage phenomenon to occur, guiding valve 10 inner chamber also forms negative pressure, sliding
The air pressure of valve 10 is tested mouth 111 and is also produced negative pressure with the interface of pressure switch 40, leads to pressure switch 40 action, now pressure is opened
Close 40 switching signals sending and show that guiding valve 10 inner seal ring produces leakage failure.
As further preferred version: connect vacuum tank between described vacuum dirt box 50 and two-position-five-way solenoid valve 20
70, connect the first check valve 80 between vacuum tank 70 and vacuum dirt box 50, the flow direction of the first check valve 80 is from vacuum tank 70
Flow at vacuum dirt box 50 place at place.First is installed unidirectional between vacuum dirt box 50 and two-position-five-way solenoid valve 20
Valve 80 and vacuum tank 70, the pressure in the vacuum dirt box 50 when guiding valve 10 cuts out reaches the negative pressure value of setting, in vacuum tank 70
Pressure consistent with the pressure of vacuum dirt box 50.Open guiding valve 10, when vacuum dirt box 50 receives dirt, vacuum reduces, the
One check valve 80 guarantees that the negative pressure value in vacuum tank 70 keeps constant it is ensured that there being enough pressure reduction to promote the piston in guiding valve 10,
The normal operation of guarantee system.
Preferably, it is connected by the second check valve 90 between described pressure switch 40 and air pressure test mouth 111, second is unidirectional
The flow direction of valve 90 is to flow at air pressure test mouth 111 place from pressure switch 40 place.
It should be appreciated that specific embodiment described above is only used for explaining the present invention, it is not intended to limit the present invention.By
Obvious change that the spirit of the present invention is extended out or change among still in protection scope of the present invention.
