Description
Technical field
The present invention relates to a kind of gate valve, particularly a kind of mechanical automatic shutoff gate valve.
Background technique
In the bigger area of rainfall rate, the agricultural drain engineering must satisfy the requirement of water logging control, in time to get rid of because the field area water that heavy rain produces reduces waterflooding time and flooding depth, guarantees the normal growth of crop.In the nonirrigated farmland, if level of ground water is too high, crop will be subjected to the stain evil and the underproduction, so the agricultural drain requirement of engineering satisfies the requirement of control and dewatering.Because soil desalination and salification all have confidential relation with phreatic buried depth, in production practices, usually judge according to bury of groundwater whether a certain area the salinization of soil can take place again.Therefore, in agricultural production, need to adopt suitable agricultural drain engineering.
Drainage measure at present commonly used has: field gutter drainage system, underground closed drainage system, mole drainage, drainage by shaft wells etc.
" field gutter drainage system ": by draining the water away at field excavation drainage channel.
" underground closed drainage system ": mainly form by several sections such as suction sleeve, collector pipe, inspection shaft, sumps.It is land drainage, prevent the effective measures of irrigateing land salinization of soil and improving the low and medium-yield farmland.Compare with gutter drainage that to have a drainage effect good, effectively control level of ground water, save the soil, reduce characteristics such as maintenance cost.
" mole drainage ": with special facility, on the face of land following certain depth place extruding soil layer and form rat hole shape passage, to get rid of the drainage measure of excessive moisture in the agricultural land soil.Its less investment, recruitment are few, instant effect, high efficiency.
" drainage by shaft wells ": by laying gang of wells, pumping underground water is with the engineering measure of control level of ground water.Drainage by shaft wells can form regional large size groundwater recession, irrigates land secondary salinization of soil or gets rid of high salinity underground water thereby prevent and treat, and also can be used for transforming shallow-layer salt water water-bearing layer.It is suitable for having the draining area employing of better water permeability soil layer.Whether if draining area soil layer bad hydraulic permeability, water yield of well is low, adopt this draining form relatively could determine by Technological Economy.

Embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
Embodiment 1
Referring to Fig. 1-4, a kind of mechanical automatic shutoff gate valve, it comprises valve body 3, valve body comprises valve chest 12, be provided with spool 13 in the valve chest, valve chest inside is divided into feed-water end 17 and waterexit end 18 by spool, feed-water end communicates with upper water box 21, the waterexit end communicates with lower header 22, water in two water tanks can circulate in two water tanks by water pump, the waterexit end is arranged with arm 6, and the arm below is provided with container 8 (the container here can be selected graduated cylinder etc. for use), and the water that utilizes container 8 to collect is heavily realized automatic shutoff for power.Container upper end is provided with hook 5, the container lower end is provided with pulley 10, pulley can slide on the skewback below the pulley 11, displacement before and after skewback can produce, outside of containers is provided with support 19, and support has scale 7, and support top is provided with switch bearing 1, be hinged with brake lever 4 on the bearing, brake lever has the first flow control cantilever 9 and the second flow control cantilever 20; The spool upper end is installed with valve rod 14, and valve rod is provided with spring 15 outward, and the valve rod upper end is hinged with switch spiral arm 2, and described brake lever lower end links to each other with hook, and master cylinder bar upper end links to each other with the switch cantilever by the first flow control cantilever or the second flow control cantilever 21; The outside, described valve chest upper end also is provided with supporting frame 16, and the switch cantilever can be around the strong point rotation of supporting frame.
Working principle of the present invention: this gate valve is a kind of automatic shutoff gate valve, utilizes Der Grundsatz der Maschinen to realize closing automatically of gate valve.When current passed through gate valve, fraction was shunted by arm, flowed in the container.The water yield increases gradually in the container, and the pipe gross weight increases.(set as required) when the water yield reaches certain value in the container, the switch cantilever overcomes the brake lever resistance, breaks away from the control cantilever, and gate valve is closed.
After switch cantilever 2 pressed, gate valve was opened, and by water pump, the water in two water tanks begins circulation up and down.The shallow bid current flow into containers 8 by shunt pipe 6, can be got the discharge relation of flow and main flow in its liquide separating tube by total stream energy equation.Hold in the graduated cylinder water-column can read by calibrated scale 7.The weight of water makes the skewback of graduated cylinder below, skewback drive roller 23 to be had and overcomes resistance and produce trend to front slide, the trend that pulley 10 and graduated cylinder 8 produce to lower slider.Its stressed equation is (as shown in Figure 3):
F=G-f
ResistanceCos θ-F
NSin θ (frictional force of chute in the skewback is only considered in the f resistance in this equation), wherein θ is the angle of skewback at vertical direction.
Container makes hook 5 produce downward power, and when the water in the container reached constant weight, hook produced enough big downward power, makes brake lever 4 produce clockwise rotation around fulcrum.When brake lever disappeared to the restraining force of switch cantilever 2, the switch cantilever was upspring under the effect of gate valve inner spring, and gate valve is closed.Because brake lever has two-stage flow control cantilever (as Fig. 2), gate valve can be realized the control of secondary effluent amount.
The present invention has purposes widely:
A) this device can combine with drainage patterns such as underground water closed drainage, mole drainages, is applied to groundwater level control, and groundwater level is controlled at a zone of reasonableness;
B) prevent from often to open the water resource waste that causes because of gate valve in the family;
C) with gate valve in the flush toilet combination, substitute the water tank on the existing flush toilet, quantitatively control water outlet, save space saves money;
D) at swimming pool, this gate valve of public place that fountain etc. need often change water also has the market competitiveness, and to change water more convenient because this gate valve can make, and manages easier;
In addition, can combine, be used for the place that needs control water level or the like of living with various devices in the life.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
