Embodiment 1

[0012] Such as figure 1 A kind of water level height keeping device described, comprises straight water pipe 3 and the pillar 9 that is vertically connected with the middle part of straight water pipe 3, and the interior of pillar 9 is provided with the wiring hole 10 that communicates with the inside of straight pipe 3, so The inside of the straight water pipe 3 is provided with a switch device, the switch device includes a fixed ring 6 coaxially arranged with the straight water pipe 3, and the inside of the fixed ring 6 is provided with a sliding rod 7 that can move axially along the fixed ring 6. One end of the rod 7 is provided with a sealing head 4 and the other end of the sliding rod 7 is connected with a backguy 11, and the backguy 11 is connected with a floating ball 12 after passing through the wiring hole 10, and the fixing ring 6 is located inside one end of the sealing head 4 and is also provided with a There is a compression spring 5, and a sealing seat 1 is arran...

Embodiment 2

[0015] This embodiment adds the following structure on the basis of Embodiment 1, specifically: the inside of the straight water pipe 3 is also provided with a rotating column 8, and the pull wire 11 is connected to the sliding rod 7 through the rotating column 8 and the floating ball 12 connections.

[0016] In this embodiment, since the floating ball 12 moves up and down, the contact friction between the backguy 11 and the water straight pipe 3 is very easy to wear and break, causing the device to lose the function of water level adjustment. Therefore, this embodiment reduces the cost of the backguy 11 Abrasion, especially in the straight water pipe 3, there is also a rotating column 8 inside. When the pull wire 11 is pulled up and down, under the action of the rotating column 8, it can not only reduce wear, but also move more flexibly and smoothly, which improves the sensitivity and device of water level adjustment. service life.

Embodiment 3

[0018] This embodiment is optimized as follows on the basis of embodiment 1 or embodiment 2: the sealing end of the sealing head 4 and the end corresponding to the water hole 2 are all tapered surfaces, and the sealing head 4 and The conical surface of the water passage hole 2 is ground by grinding.

[0019] The sealing end of the sealing head 4 of this embodiment and the corresponding end of the water hole 2 are all tapered surfaces, so that the two seals are more fit, and it can ensure that the sealing head 3 will not leak when sealing. At the same time, the sealing head 4 and the The conical surface of the water passage hole 2 is ground by grinding, which can further improve the bonding degree of the two, can ensure the sealing performance, and improve the accuracy of water level adjustment.

Abstract

The invention discloses a water level height keeping device. The water level height keeping device comprises a water passing straight tube and a supporting column which is vertically connected with the middle part of the water passing straight tube. A wire passing hole which is communicated with the inside of the water passing straight tube is formed in the supporting column. A switching device is arranged inside the water passing straight tube, the switching device comprises a fixing ring which is coaxially arranged with the water passing straight tube, and a slide bar which can move in the axial direction of the fixing ring is arranged inside the fixing ring. A sealing head is arranged at one end of the slide bar, the other end of the slide bar is connected with a pulling wire, and the pulling wire penetrates through the wire passing hole and then is connected with a floating ball. A compression spring is further arranged at the position, located at one end of the sealing head, inside the fixing ring. A sealing base corresponding to the sealing head is arranged inside the water passing straight tube, and the sealing base is provided with a water passing hole. The designed automatic water level height keeping device is simple in structure and low in cost, no electric device or control system is used, the cost is low, water level adjustment can be conducted automatically by connecting and disconnecting a water pipe according to the water level, and thus the water level height keeping device is economical and practical.

Description

technical field [0001] The invention relates to a water level maintaining device, which belongs to the field of mechanical control, in particular to a water level maintaining device. Background technique [0002] In some mechanical processing and manufacturing, metallurgy, petroleum, pharmaceutical and other fields, limited by the environment and use conditions, some buckets and water tanks for storing water need to maintain a certain water level to meet normal use, that is, if the height of the stored water is not enough , the normal water supply or insufficient water supply due to insufficient pressure difference will lead to errors in processing water and affect production. In the past, the water level was controlled by detecting devices such as sensors and liquid level gauges, and then notifying the staff through the control system or controlling the valve to cut off the water level. In some pipelines with low requirements, the cost is high and it is not economical, so i...
