Description

Multi-period from control draining valve

Technical field

The utility model relates to electromagnetism drain valve product manufacturing technology field, especially refers to a kind of structure technology of drain valve body cavity runner.

Background technique

The technician of pneumatic industry knows all that generally common atmospheric air is after compressing at high proportion, because the variation of pressure and temperature can produce a spot of liquid water of condensation and impurity; Therefore compressed gas source need carry out filtration treatment before entering the pneumatic control system loop, in time gets rid of these water of condensation and impurity, prevents to cause that inner-walls of duct corrosion and valve core through hole stop up, and ensures the proper functioning and the working life of each Pneumatic component.For those water of separating and impurity, early stage way is to shut down the back by getting rid of manually, wastes time and energy; The someone had invented a kind of electronic drain valve product afterwards, had solved preferably in an automatic draining difficult problem of not shutting down under the band operating air pressure situation.But in sum; because the atmospheric air after the compression is isolated some impurity through regular meeting; the filter screen that these impurity are easy to stop up in the drain valve by spool the time causes the draining difficulty; so also necessary regular dismounting drain valve of operator; the impurity that is attached on the filter screen is removed, could be guaranteed its proper functioning.

The model utility content

The technical problems to be solved in the utility model is to overcome to remove inconvenient defective and deficiency after the impurity that has the like product existence now is attached to filter screen, provide a kind of to society and can remove the drain valve product that impurity on the filter screen and the multi-period setting drain valve of tool open and close function quickly and easily, discharging is required automatically to satisfy the water of condensation of middle-size and small-size air compressor, compressed air line system.

The technological scheme that its technical problem that solves the utility model adopts is: the multi-period valve body that comprises tool water inlet interface, vertical joint and drainage interface from control draining valve; Described vertical joint is connected with solenoid valve, and the coil of described solenoid valve is connected with multi-period timer; Described vertical joint is provided with the draining valve port corresponding to described electromagnetism valve actuation iron core, described draining valve port inner chamber is communicated with described drainage interface, exocoel is communicated with described water inlet interface through vertical passage, and the described water inlet interface internal chamber wall of described vertical passage lower end mouth is embedded the ring-type filter screen; Described valve body is provided with and the coaxial sewage draining exit of described water inlet interface, and described sewage draining exit inner chamber is established the ball valve core, and the Joystick of described ball valve core is located at described valve outer wall.

The described ball valve core left and right sides is established sealing gasket and is fixed by gland.

Described sewage draining exit port is provided with internal and external screw thread; Described water inlet interface is connected with the transit joint of tool internal and external screw thread, is embedded seal ring between described transit joint and the described water inlet interface.

The utility model is multi-period from control draining valve, and the keying work by multi-period timer control electromagnetic valve realizes automatic drain function.When the operation of this product need be removed impurity on the filter screen a period of time, only the Joystick that need press valve outer wall is opened sewage draining exit, having the air of operating air pressure and water of condensation passes through fast from the inner chamber of ring-type filter screen, formation is to the scouring effect of its internal chamber wall, thereby the impurity that will be attached to ring-type filter screen inwall is peeled off removal, and is simple and fast.Compare than existing product, this product has simple in structure, easily manufactured advantage, is widely used in the automatic discharging of the water of condensation of middle-size and small-size air compressor, compressed air line system.

Embodiment

As shown in Figure 1, the utility model is multi-period to comprise that from control draining valve section is the valve body 1 of threeway shape, and an end of described valve body 1 is water inlet interface 10, and the other end is a sewage draining exit 2, the vertical joint 3 that is positioned at the middle part is connected with solenoid valve 5, and the coil of described solenoid valve 5 is connected with multi-period timer 4.Described vertical joint 3 centers are provided with draining valve port 8, and described draining valve port 8 is corresponding to the moving iron core 6 of described solenoid valve 5; One side of described draining valve port 8 is provided with vertical passage 9 and is communicated with described water inlet interface 10 inner chambers, is embedded ring-type filter screen 13 corresponding to described water inlet interface 10 internal chamber walls of described vertical passage 9 lower end mouth; Valve body 1 inner chamber of described sewage draining exit 2 inboards is established ball valve core 11, and described ball valve core 11 left and right sides are established sealing gasket 12 and fixed by gland 14.As shown in Figure 2, the Joystick 19 of described ball valve core 11 is located at described valve body 1 outer wall.As shown in Figure 3, described vertical joint 3 is provided with drainage interface 15 radially, and described drainage interface 15 inner chambers are provided with the inner chamber that radial passage 16 is communicated with described draining valve port 8.Connection for the convenience of the user, described sewage draining exit 2 ports are provided with inside and outside two screw thread, and described water inlet interface 10 is connected with the transit joint 17 of the inside and outside two screw threads of tool, is embedded seal ring 18 between described transit joint 17 and the described water inlet interface 10.

Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.During the work of this product, power supply is connected with solenoid valve 5 through multi-period timer 4; The user can produce flow and set up the blanking time of draining on their own according to the water of condensation of the middle-size and small-size air compressor that is connected, compressed air line system, thereby reaches self-draining function.When multi-period timer 4 conductings, spring 7 resistances that the moving iron core 6 of solenoid valve 5 overcomes its upper end rise, draining valve port 8 is opened, the water of condensation that is entered by water inlet interface 10 rises to draining valve port 8 outsides through vertical passage 9, is discharged by drainage interface 15 behind the radial passage 16 of draining valve port 8 inner chambers, drainage interface 15.When ring-type filter screen 13 that the water of condensation that has impurity is embedded through water inlet interface 10 internal chamber walls, impurity is barred from ring-type filter screen 13 inboards.When the operation of this product need be removed impurity on the filter screen a period of time, only need to press the Joystick 19 of moving valve 1 outer wall, ball valve core 11 is opened sewage draining exit 2, having the air of operating air pressure and water of condensation passes through fast from the inner chamber of ring-type filter screen 13, formation is to the scouring effect of its internal chamber wall, thereby the impurity that will be attached to ring-type filter screen 13 inwalls is peeled off removal, and is simple and fast.
