Abstract
The utility model relates to a liquid-level alarm interlocking device which comprises a floating ball, a connecting rod, a rotating shaft, a fixed shaft sleeve, a pointer and a stroke switch. The liquid-level alarm interlocking device is characterized in that: the rotating shaft and the floating ball are connected into a whole through the connecting rod, a retainer ring is arranged on the rotating shaft, the rotating shaft is inserted into the fixed shaft sleeve and limited by the retainer ring, and the rotating shaft and the fixed shaft sleeve are sealed by using an O-shaped seal ring; the end part of the pointer is provided with a shaft sleeve and fastened with the rotating shaft through the shaft sleeve; the stroke switch is fixedly connected with the fixed shaft sleeve; and a retainer ring is arranged at one end of the rotating shaft. The utility model is suitable for upper-limit or lower-limit alarm control of the liquid level of liquids in various mobile vessels with a certain pressure, can realize the bit-type control of the liquid level by matching with a control circuit and is especially suitable for a special pot-type vehicle for loading liquid. The utility model has the characteristics of simple structure and reliable running without being maintained basically, can not only observe the liquid level in situ, but also carry out remote programmed operation and realize the interlocking control of the liquid level.
Description
Technical field
The utility model relates to the chain control device that a kind of machinery adds electrical equipment, and particularly a kind of level alarm interlock is mainly used on the mobile containers.
Background technology
Development along with national economy, the raising of automaticity, demand to liquid level instrument constantly increases, along with autonomous innovation, own development of technology, the ratio of the liquid level instrument production domesticization that process automation is required is also increasing, and form also is varied, as ultrasonic level gage, magnetic upset liquid level gauge, static pressure (differential pressure) formula liquid level gauge, servo liquid meter, float level meter etc., the complex structure that these products have, the cost height; The volume that has is big, and inconvenience is installed, and the complex operation that has is fragile.
Summary of the invention
The purpose of this utility model is in order to overcome the problem that above-mentioned prior art exists, and a kind of level alarm interlock is provided, and this apparatus structure is simple, and is easy for installation, reliability and durability.
The purpose of this utility model can realize by following technical proposals:.
The level alarm interlock, comprise ball float, connecting rod, turning axle, fixed hub, pointer, travel switch, it is characterized in that: turning axle fuses by connecting rod and ball float, on turning axle, be provided with back-up ring, turning axle inserts in the fixed hub also spacing by back-up ring, and with the O-ring seals sealing, the pointer end is provided with axle sleeve between turning axle and the fixed hub, fastening by axle sleeve and turning axle, travel switch is fixedlyed connected with fixed hub.
The utility model is applicable to the upper limit or the lower limit controlling alarm of various mobile and liquid in container liquid levels that certain pressure is arranged, cooperates with operation circuit, can realize the position formula control of liquid level, is specially adapted to load and unload in the pot type special car of liquid use.The utility model characteristics are simple in structure, and running is reliable, need not safeguard basically.But on-site-inspection liquid level, but also teletransmission program control operation realize the chain control of liquid level.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model comprises ball float 10, connecting rod 9, turning axle 6, fixed hub 5, pointer 1, travel switch 4, turning axle 6 fuses by connecting rod 9 and ball float 10, and corresponding position is provided with back-up ring 8 on turning axle 6, turning axle 6 inserts in the fixed hub 5 also spacing by back-up ring 8, seal with O-ring seals 7 between turning axle and the fixed hub, pointer 1 end is provided with axle sleeve 3, fixing by axle sleeve and turning axle 6 usefulness holding screws 2, travel switch 4 is fixedlyed connected with fixed hub 5, unclamps holding screw 2 backpointers 1 and can regulate direction.
When using the utility model, fixed hub 5 of the present utility model directly is welded on the tank body of container 11 of dress liquid, and the general inserts the fixed hubs 5 from tank body 11 inboards with the turning axle 6 that connecting rod 9 and ball float 10 fuse, again the pointer 1 that has axle sleeve 3 is fixed on the turning axle 6, liquid level in tank body 11 changes, ball float 10 is being with connecting rod 9 to rise or descend, thereby driven rotary axle 6 and pointer 1 motion, pointer 1 promotes the swing arm of travel switch 4, reach contacting or disconnection in the travel switch 4 when setting liquid level, give corresponding topworks such as valve, electric signal such as pump, it is begun or quit work, thereby reach liquid level in the control tank body 11.
The utility model is applicable to the upper limit or the lower limit controlling alarm of various mobile and liquid in container liquid levels that certain pressure is arranged, cooperates with operation circuit, can realize the position formula control of liquid level, is specially adapted to load and unload in the pot type special car of liquid use.Its feature is simple in structure, and running is reliable, need not safeguard basically.But on-site-inspection liquid level, but also teletransmission program control operation realize the chain control of liquid level.
