Further, the through-hole horizontal cross-section is less than open ports horizontal cross-section, and through-hole horizontal cross-section is less than float most
Big horizontal cross-section.
Further, the level height of the input port is lower than the level height of delivery outlet.
Further, the magnetic switch is arranged on upper body outer wall at upper body bottom, the float bottom
Portion offsets with lower case, and magnetic switch detects the magnetic field of magnet ring, and in pipeline in the operation of full liquid status, the float floats,
Magnet ring and magnetic switch induction disconnect.
Rationally, liquid is entered in shell by input port in input channel for the configuration of the present invention is simple, design, is injected in liquid
In the process, liquid is entered in upper body by through-hole in lower case, and squeezes air, so that air is through check-valves and bypass
Pipeline enters in output channel, and float rises with liquid level in upper body and risen, and the magnet ring and magnetic switch on float incude
It disconnects, magnetic switch issues signal and shows that output channel is run in full liquid status, and liquid is flowed out by output channel in shell.
Float and magnet ring split-type design, to reduce production cost, input channel and output channel connect with lower case
It connects, the connection of this part is less prone to failure, and float, magnet ring, magnetic switch and check-valves etc. are prone to wear or the part of failure is all provided with
It sets in upper body, upper body can be removed from lower case, easy to repair or renewal part, using more convenient.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of embodiment one.
Fig. 2 is enlarged drawing at A in embodiment one.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments:
Embodiment one, referring to shown in Fig. 1-2, a kind of liquid conducting pipes expire liquid detection device, including float 3, magnetic switch 4 and shell
Body, shell are equipped with the input port 21 connecting with input channel 7 and the delivery outlet 22 connecting with output channel 8, the shell
Including upper body 1 and lower case 2,1 bottom surface of upper body is equipped with open ports 13, and 1 bottom of upper body is outward extended with
Convex edge 14,13 position of open ports is corresponded at the top of the lower case 2 equipped with through-hole 20, corresponding upper convex edge 14 at the top of lower case 2
Position is provided with lower convex edge 15, upper convex edge 14 and lower convex edge 15 and is connected by bolt 5, and the connection of upper convex edge 14 and lower convex edge 15
Face be equipped with sealing element 6, sealing element 6 be preferably sealing ring so that upper body 1 and lower case 2 sealed connection be combined into
The confined space of portion's connection, by-pass port 16 is equipped at the top of the upper body 1, and by-pass port 16 is equipped with check-valves 9, the lower part
Shell 2 is equipped with the input port 21 and delivery outlet 22, and the level height of preferred input port 21 is lower than the level of delivery outlet 22
Highly, check-valves and delivery outlet 22 are connected by by-pass line 10, and the air in upper body 1 is discharged to and delivery outlet 22
In the output channel 8 of connection.
Wherein 20 horizontal cross-section of through-hole is less than 13 horizontal cross-section of open ports, and 20 horizontal cross-section of through-hole is less than 3 maximum of float
Horizontal cross-section.
The float 3 is equipped with magnet ring 11, and float 3 and magnet ring 11 be set along in upper body 1,3 bottom of float with
Lower case 2 offsets, and magnetic switch 4 detects the magnetic field of magnet ring 11, and in pipeline in the operation of full liquid status, the float 3 floats,
Magnet ring 11 and the induction of magnetic switch 4 disconnect, and magnetic switch 4 is arranged on 1 outer wall of upper body.
In the present embodiment, the magnetic switch 4 is arranged on 1 outer wall of upper body at 1 bottom of upper body, float 3
Through-hole 20 can not be passed through to enter in lower case 2, to prevent float 3 from entering in lower case 2, magnet ring 11 and magnetic switch 4 incude
It disconnects, magnetic switch 4 also issues the signal of full liquid operation.
Liquid in input channel 7 is entered in lower case 2 by input port 21, is entered from the output of delivery outlet 22 defeated
Pipeline 8 out form the prevailing transmission channel of liquid.Since input channel 7 is in the lower section of output channel 8, under liquid entrance
The liquid stream of one uplink is formed when portion's shell 2, main liquid stream enters output channel 8 from delivery outlet 22, and part liquid stream passes through through-hole
20 enter in upper body 1 through open ports 13, and upper body 1 is upwards lifted float 3, with the injection of liquid floating
During son 3 rises, 3 top of float is flowed by check-valves 9 through by-pass line 10 with the air in the cavity of upper body 1
To output channel 8, float 3 rises with the liquid level of upper body 1 and is risen rapidly, and the magnet ring 11 of float 3 leaves magnetic switch 4
, stop signal output, display conveyance conduit run in full liquid status.
In the process, it as the air above upper body 1 and float presses to check-valves 9, is flowed through by-pass line 10
To output channel 8, upper body 1, bypass pipe 10 and output channel 8 are hydraulically full, and check-valves 9 is closed after pressure balance, keep away
Exempt from liquid transmission line pressure ratio upper body it is high when float is pushed down on, generate error signal output.
When input channel 7, which is transported to this liquid conducting pipes without liquid, expires liquid detection device, the intracorporal liquid of shell subtracts
Small, float 3 returns to origin-location, and magnetic switch 4 detects the magnetic field of magnet ring 11 and issues signal, prompt conveyance conduit in liquid not
Foot.
