The multi-functional water pump controls valve one, use installation and surfaces in the water pump on the pipeline, have electronic valves, dispelling device three kinds of functions of the valve and water hammer against the current concurrently, improve the safe reliability of supplying water effectively, accord with the mechanized and automatic requirement of the apparatus of water engineering.

Second, characteristic 1, dispelling water hammer dependability high. Close the device and open, close with mainly fining one edition of chain movements slowlyRealize automatically that closes rapidly, is not influenced by the actual flow of the water pump, lift fluctuation, do not need to close time to calculate rapidlyDo not need professional and technical personnel to change liveNot needing any electric apparatus and oil pressure component, there are less trouble points. 2, It is effectual to dispel water hammer. Close, close slowly rapidly and who technological principle integrated design that blow it will be water hammer three elimination of absorbing etc., enable and stop pump water hammer pressure and subside to the minimum limit. 3, It is convenient to operate and safeguard. Only need to operate opening and closing the button of the water pump electrical machinery starter, the valve realizes promptly that opens and closes automatically according to the water pump operational procedure. The key part selects the high-quality material for use, does not basically need to safeguard. 4, Energy-conservation is effectual. Adopt streamlined, body of fund valve and latest patent technical design, compare with imported like product, resistance losses are reduced by more than 50%.

Fourth, multi-functional water pump of the structure (Fig. 1) controls the valve and is made up of main valve and appearance attachment, the main valve is made up of major parts such as body of valve, the diaphragm (piston jar), valve stem package, main valve board, valve seat,etc., put the attachment and mainly control the valve, filter, empty the valve, little non-return valve outside, among them the little non-return valve is the purpose-built fittings, stop going back to have and flow the hole limitedly in direction in it. 2, Manual operation opens and closes when the water pump operates, control the control valve which feeds through the diaphragm control room (piston jar) and empty the valve manually first, make P3 or P4 pressure equal zero, diaphragm pressing plate or piston bears pressing one-wayly, the situation of opening and closing of the checkable valve board. When the valve is opened, because close the valve board and rise slowly, the main valve board is cast aside and realized opening movements by the riversWhen the valve is closed, close the valve board and push the valve board to close slowly.

Sixth, install the general attentive matters of attentive matters (Fig. four): 1, Before installing, please check first whether every part of the main valve is intact, firm one is complete, have not become flexible. 2, It is intact to check every connection pipeline, connect and fasten. 3, Guarantee the minimum movement pressure accords with the technical parameter requirement. 4, The best installation way is to install the main valve on the horizontal pipeline, the valve is covered up. 5, If install the main valve in the overcast well, should leave certain space and prepare against a technical staff to overhaul. 6, While installing, please notice the external arrow point of the valve pointing out the direction, can't put instead. 7, If want, go on, adjust, press and observe working pressure, must end install the manometer in imports and exports. 8, Using for fire control should start the inspection regularly, prevent producing the scale, cause the valve not to work. Special attentive matters: 1, At the time of installation, pay attention to checking and washing the pipeline, can't weld foreign matters such as the dreg, bolt,etc.. 2, It should be according to standardizing the requirement to install relevantly into devices such as the vent valve,etc. that the pipeline is installed, guarantee not to produce the water column to cut off. 3, Imports one and does not get installation flexibility connecting or flexible device of pipeline with valve. 4, May produce the pump station that water hammer endangered, should stop the pump water hammer to calculate.

Seventh, debug step 2, manual operation to examine: (1)Open the pump and observe every key and leak, the pressure of imports and exports of the valve is normal. (2)Open, control the valve (14) to closeEmpty the valve (15) to close, and then empty the valve (7) to open, air or water discharges, prove the valve board is openedThe valve board is opened and put in place, have no water to flow out, prove to empty the valve (7) that punishes by law openingThe valve board is opened and put in place, have no water to flow out, prove the diaphragm piston jar intact to empty the valve (7)Emptying the valve (7) stills have water to flow out, then the diaphragm is damaged. (3)The valve is closed manually: Thread a pipe control (2) valve at shut off, control (14) valve turn on, (7) vent valve shut off, and then empty the valve (15) to open, water will be discharged, close the valve board and push the main valve board to close slowlyWhile there is no water to discharge, indicate the valve board has already been totally closed. If valve board shut off after empty by (15) of valves it flow out for water,know sets coherent of diaphragm flat (cylinder block) reveal already (seal enclose already " O " type that put Open and close from two the above movement can examine valve stem movement two reliable. Closing the checkable valve board of the tightness to close, have rivers sound or observe the pipeline flow meter of valve board. 3, Stop the pump and close time to adjust slowly: The ones that stop the pump and close time and can through regulating the by-pass pipe slowly are accused of Make the opening degree and is regulated of valve (14), should control the valve to make fun of first, will lengthen and close time slowly. Enter, close, too long, control to turn on degree increase, or increase and join the pipeline requirements (14) valve slowlyClose time to be too short slowly, can control to turn on degree turn down (14) valve. If find abnormality, please deal with or contact our company directly according to way of Table 2.
