Description
Technical field
The utility model relates to a kind of water filling device, especially a kind of automatic constant-pressure metering water filling device.
Background technology
In building the highway process, run into the situation that has grotto under the roadbed through regular meeting.At this moment need with cement paste its perfusion to be tamped, the existence that solves because of grotto makes the unsteady problem of roadbed.
Need to adopt hole wall imaging technique and infiltration test that injected hole is tested in the karst roadbed processing procedure, to determine the amount of filling in of cement paste.Infiltration test is to adopt to inject a certain amount of water in the hole, and the loss water yield of observing water defines the development degree of underground karst.The artificial mode is generally adopted in this work, utilizes water pump that water is injected grotto, and the flow meter meter record water injection rate on the discharge pipe line calculates the volume that needs perfusion then.The shortcoming of this method is whole process need personnel nurse, and waste of manpower has greatly increased labour intensity, and 10 personal works just can be finished the perfusion of about 50 left and right sides grottos in 12 hours; In case because of phenomenon appears running, emits, leaks in personnel's carelessness or plant failure, will directly influence the result accurately, contain bubble in the water of being discharged because of the effect of water pump will make simultaneously, influence the counting of flow meter, make the result deviation occur.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of design science rationally, can efficiently carry out the water filling operation and can accurately calculate the automatic constant-pressure metering water filling device of water injection rate.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of automatic constant-pressure metering water filling device, advancing, arrange mouthful inlet pipe, drain pipe that are connected by control cabinet, with the motor of control cabinet electrical connection, with the coaxial mounted water pump of motor and with water pump forms, one flow meter is installed on gutter, the drainpipe outlet end is equipped with a draining valve, it is characterized in that: pressure water pot, flow switch and pressure switch are installed on the gutter of water pump, and flow switch is electrically connected with control cabinet respectively with pressure switch.
And, on the water inlet pipe of described water pump one way stop peturn valve is installed.
Advantage of the present utility model and beneficial effect are:
1, the flow switch of this automatic constant-pressure metering water filling device is used for flowing of water sensing, when it senses flowing of water, and the flow switch closure, thus make starting mode of pump, be system water supply; Pressure switch is mainly used in and prevents to reveal, if when system pressure is lower than the low pressure setting value of pressure switch, starting mode of pump is a system water supply; When hydraulic pressure in the system reaches setting value, the pressure switch action, water pump quits work, thereby has realized the automation of water pump start-stop in the injecting process, has improved the work effect greatly, has saved expenditure.Use this device, 3 people can finish the perfusion of more than 100 grotto in 8 hours.
2, this automatic constant-pressure metering water filling device is equipped with the pressure water pot in the water side, can effectively alleviate the water pressure fluctuations of system, also can drive away the bubble in the draining simultaneously, avoid the influence of bubble to flow meter, therefore, can make the water flow meter of under the situation of constant pressure, flowing through inject grotto smooth-goingly, guarantee precision of test result.
3, this automatic constant-pressure metering water filling device is simple in structure, reasonable in design, and infiltration test technology that the use of this equipment is perfect has improved the ability that solves a difficult problem that runs in the on-the-spot real work.
4, the utility model is simple in structure, reasonable in design, has realized the automation of water pump start-stop in the injecting process, has improved the work effect greatly, has saved expenditure; Can make simultaneously the water flow meter of under the situation of constant pressure, flowing through inject grotto smooth-goingly, guarantee precision of test result.
Description of drawings
Fig. 1 is the schematic diagram of system architecture of the present utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of automatic constant-pressure metering water filling device, as shown in Figure 1, water source 1 links to each other with the water inlet of water pump 4 by water inlet pipe 2, and an one way stop peturn valve 3 also is installed on water inlet pipe; The delivery port of water pump connects gutter 6, and this gutter can communicate with the grotto mouth.One pressure water pot 5 is installed on gutter, simultaneously, flow switch 7, pressure switch 8 and flow meter 9 is installed also on gutter, one draining valve 10 is installed at the port of export of gutter.The control cabinet 11 of system is electrically connected with pump motor 12, flow switch and pressure switch.
When beginning in grotto during water filling, internal system hydraulic pressure is higher, draining valve flows out immediately under can the effect at system pressure once fetching boiling water just and injects grotto, the similar water injecting metering rifle of draining valve this moment.At this moment do not reduce as yet under the too many situation at system's hydraulic pressure, flow switch can sense flowing of water and move, and makes the flow switch closure, and control of pump starts, and is system water supply, avoids system pressure to reduce too much, prevents that system pressure from producing excessive fluctuation.
After the grotto water filling is finished, close draining valve, system water voltage rise height, the pressure electromagnetic device valve events is closed down water pump.
When sewing appearred in system, during particularly little leakage, intrasystem small current were not enough to make the flow switch action, at this moment, when intrasystem pressure dropped to a setting value, the pump motor power supply was connected in the pressure switch action, start water pump, be system's water-filling, keep system's water pressure invariableness.
Claims (2)
1. an automatic constant-pressure measures water filling device, advancing, arrange mouthful inlet pipe, drain pipe that are connected by control cabinet, with the motor of control cabinet electrical connection, with the coaxial mounted water pump of motor and with water pump forms, one flow meter is installed on gutter, the drainpipe outlet end is equipped with a draining valve, it is characterized in that: pressure water pot, flow switch and pressure switch are installed on the gutter of water pump, and flow switch is electrically connected with control cabinet respectively with pressure switch.
