Description

The invention relates to the field of measurement technology.

Gauge devices are known in which a membrane is located at one end of a tubular corus, and a contact group at the other end is connected to a stem membrane, and the device is equipped with a spring-setting mechanism for setting its limit.

However, in such a device, there is no simple independent setting of the limit of response and deflection of the membrane to one and the other side.

In the proposed sigalizer, the spring setting mechanism is made in the form of two compressed springs separated by a wheel reinforced in a tubular body, which is a partition, and HITOK is equipped with a protrusion that interacts with M as a function of the direction of movement of the rod with one spring or the other.

This allows for independent adjustment of the triggering of the sigalizer and the upper and lower limit levels.

FIG. 1 shows an alarm device at the lower level of the liquid in the tank; in fig. 2 - the same, with the upper level of the liquid.

On the extended part of the tubular body 1, the membrane 2 is fixed from elastic material, and inside the corns in the sleeves 3, 4, 5 there is a slip-slide;

The rod 6 is mounted. In the upper part, a protrusion 7, washers 8, 9, springs 10 and // and a fork 12 are fixed on the rod. A toggle switch 14 is mounted on the top of the cover 13. A bracket 16 is attached to the flange 15 for mounting the device in the tank body. Inside the corus is placed emphasis 17.

The detector works as follows.

But when the diaphragm reaches the lower level of the water in the reservoir under the action of the weight of the rod and bends downwards, at this moment the toggle lever moves downwards. In this way, the command to turn on the pump can be given to refill the tank.

The stem supports the spring 10, the compression of the spring and the intensity of the lowering of the stem is adjusted by the sleeve 4, which is included in the threaded connection with the flap 15. The upper spring 11 does not participate in moving the stem down, since the action of this spring is limited by the washer 8 on the stop 17.

But as the tank is filled with water (Fig. 2), the pressure on membrane 2 increases and it is pressed inward, moving the rod 6 upwards. Mizhi spring 10 at this moment rests on the washer 9 on the stop 17 and does not participate in the movement of the rod up. Through lines 7 and washer 8, the rod, moving, compresses the spring 11, the degree of compression of the spring is controlled by the sleeve 5, which enters the threaded connections with the cover 13. Upon reaching the upper limit of movement, the fork 12 moves the toggle lever 14 up, thereby giving the command stopping the pump and stopping the supply of water to the tank. The subject of the invention is a gauge liquid level indicator comprising a tubular body, at one end of which a membrane is located. and on the other, a contact group, a rod connecting the diaphragm with a contact group, and a spring adjustment mechanism, characterized in that, in order to ensure an independent adjustment of the operation of the alarm device by the upper and lower limit levels, its spring adjustment mechanism is designed as two compressed the springs are separated by an annular partition fixed in the tubular body, and the brush is provided with a protrusion that interacts with one or the other depending on the direction of movement of the brush.
