The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment in the present invention is described in further detail.
As depicted in figs. 1 and 2, the hydraulic controller with check function with precision adjusting the present invention relates to, include control circuit 1, intake pressure transmitter 2 and intake pressure transmitter interface 4, also include main valve 24, water inlet guiding loop 18 and water outlet guiding loop 19, described main valve 24 is by valve body 5, upper valve distinguishes 7, lower valve distinguishes 10, valve rod 9 and valve pocket 20 form, on described valve body 5, be provided with water inlet pipe 21 and outlet pipe 22, on the intersection of water inlet pipe 21 and outlet pipe 22, be provided with cut-off mouth 23, described upper valve distinguishes that 7 are arranged in valve pocket 20, the upper end of valve rod 9 is fixed on valve and distinguishes on 7, described lower valve distinguishes that 10 are fixed on the lower end of valve rod 9, lower valve distinguishes that 10 are pressed on cut-off mouth 23, described water inlet guiding 18 two ends, loop are connected with water inlet pipe 21 and valve pocket 20 respectively, described water outlet guiding 19 two ends, loop are connected with outlet pipe 22 and valve pocket 20 respectively, described intake pressure transmitter interface 4 is arranged on water inlet pipe 21, intake pressure transmitter 2 is inserted in intake pressure transmitter interface 4, intake pressure transmitter 2 is electrically connected mutually with control circuit 1.
Described water outlet guiding is parallel with flap valve 17 and motor operated valve 3 on loop 19, on water inlet guiding loop 18, be serially connected with reducing valve 15, on water inlet guiding loop 18, be provided with pressurizer 16 and guiding loop pressure transmitter 14, described motor operated valve 3 is electrically connected with control circuit 1 respectively mutually with guiding loop pressure transmitter 14.
Be positioned on the valve body 5 of valve pocket 20 belows and be provided with sealing ring 11, described valve rod 9 upper ends are in sealing ring 11 extend into valve pocket 20, on described valve rod 9, be set with spring 12, the lower end of described spring 12 is pressed on lower valve and debates on 10, and the upper end of spring 12 is pressed on valve body 5 inwalls.
Be positioned on the valve body 5 of valve pocket 20 tops and be provided with discharge opening 6, on discharge opening 6, be provided with capping 8.
Described water inlet guiding is provided with pressure meter 13 on loop 18.
When work, intake pressure transmitter 2 detects upper end while coming water pressure to approach setting pressure, and signal is passed to control circuit 1, and control circuit 1 is controlled motor operated valve 3 slowly closings, reduce the water yield of valve pocket 20, thereby cause the cavity pressure of valve pocket 20 to rise, and be applied on flap 7, the downward pressure of generation increases, by valve rod 9, connecting lower Disc 10 moves downwards, reduced the open degree of valve, thereby reduced the water withdrawal from city planting ductwork, to ensure the pressure of upper end pipe network; When intake pressure transmitter 2 detects upper end and comes water pressure higher than setting pressure, through intake pressure transmitter 2, signal is passed to control circuit 1, control circuit 1 is controlled motor operated valve 3 and is slowly opened, increase the water yield of valve pocket 20, cause valve pocket 20 pressure drops in valve body 5, the downward pressure that is applied to flap 7 reduces, and by valve rod 9, connects upwards action of lower Disc 10, increased the open degree of valve, thereby increased the water withdrawal of fetching water from city planting ductwork.
Described water inlet guiding loop 18 is connected with pressurizer 16, then is connected with the valve pocket 20 of main valve 24 after reducing valve 15, by reducing valve 15, can expand the pressure reduction with valve pocket 20, reduces the response time of main valve 24; When intake pressure transmitter 2 detects upper end water and approaches setting pressure, motor operated valve 3 slowly closings, pressurizer 16 can make valve pocket 20 pressure rises steadily slow, there will not be obvious fluctuation, improves the control accuracy of valve.
When the valve pocket 20 of main valve 24 guides main valve 24 outlet pipe 22 pressure in loop 19 to be greater than water inlet pipe pressure by water outlet, the water of outlet pipe 22 can enter valve pocket 20 by flap valve 17 paths, main valve 24 is closed, make valve itself there is the function of non-return, described control circuit 1, the pressure detecting through intake pressure transmitter 2, the switching of controlling motor operated valve 3 realizes allomeric function, on valve rod 9 in valve body 5, spring 12 is installed, can strengthens downward dynamics, be conducive to the opening and closing of valve; By guiding loop pressure transmitter 14, send to control circuit 1 and carry out alarm.
