Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment:
As illustrated in fig. 1 and 2, this utility model is mainly made up of many spray orifices main valve, hydraulic cylinder drive mechanism, controlling organization three part.
Primary clustering of the present utility model forms by driving beam 1, inner rocker arm 10, outer rocker arm 3, Withdrawing pin, rotary shaft 4, hydraulic cylinder 6, outlet 11, inlet tube 7, air deflector, valve body 2 and commutator 13.
Jet pipe 12 is many jet orifice structures, and many jet orifice structures can realize the cavitation resistive property under High Pressure Difference, low discharge, can realize flow linear regulation simultaneously, improve the service life of valve, thus promote whole valve Long Service Life.
Hydraulic cylinder 6 controls the different directions of piston movement by piston left and right pressure difference, valve opening utilizes hydraulic cylinder drive mechanism, by pressure relief pilot-actuated valve induction system front end hydraulic pressure, regulates hydraulic cylinder 6 piston pressure at both sides, realize water hydraulic cylinder piston motion, thus realize valve switch and aperture regulation.
Hydraulic cylinder 6 of the present utility model automatically controls, and power source is system pressure itself, need not any external power supply, source of the gas and hydraulic power source single-candidate exterior power source.
Hydraulic cylinder 6 drives many spray orifices pressure release holding valve to utilize the spray orifice head-on collision principle being distributed on jet pipe 12 circumference, changes nozzle hole number, orifice size, consumes fluid energy, thus reaches reduce pressure energy dissipating or control the purpose of flow.The work of many spray orifices pressure release holding valve is to move before and after the aperture size by the pressure relief pilot-actuated valve on control piper controls water vat, thus band moving sleeve lock 9 seesaws, and changes nozzle hole area, reaches the purpose maintaining system pressure less than setting value.Spray orifice is circumferentially, and water flows through head-on collision kinetic energy and cancels out each other, and reduces the erosion to valve body；Many spray orifices type holding valve design uniqueness, its aperture is linear with negotiability, and driving force is little, flexible operation, and anti-seismic performance is strong, and when valve wide open, its flow resistance coefficient is low, and is difficult to jam.
Controlling organization of the present utility model is as shown in Figure 3, controlling organization is the sub-pipeline of redundancy that two nested structures are identical, substantially ensure that the safety of system, during normal work, two reduce pressure pilot valve JA, JB outlet pressure is set in about 0.7MPa (shown in table G2/G2 '), the discharge pressure of pressure relief pilot-actuated valve XA is set in 1.8MPa, the discharge pressure of pressure relief pilot-actuated valve XB is set in about 1.9MPa, the discharge pressure that during valve working, pressure relief pilot-actuated valve XA opens, maintain system front end pressure less than 1.8MPa, just in case pressure relief pilot-actuated valve XA breaks down, in emergency circumstances pressure relief pilot-actuated valve XB automatically opens up release system pressure, ensure that system pressure is less than about 1.9MPa.
Operating principle of the present utility model and operating procedure are as follows:
1), after confirming to carry out according to erection code, can debug.
2) before debugging, before this valve, isolating valve should open a part (about 50%), not standard-sized sheet.
3) whether PLSCONFM many spray orifices holding valve is in open position, please guarantee that debugging early gate is in the open position (aperture is more than 50%).
4) when debugging, two overlap the sub-pipeline of redundancy, a set of need is closed, ball valve BV1 ', BV3 ' are closed, needle-valve NV and NV ' standard-sized sheet, remaining control piper valve is both needed to open, two pressure relief pilot-actuated valve regulation bolts all loosen, two decompression pilot valve JA, JB regulation bolt pressure half, it is ensured that the safety of system.
5) open water pump, open on hydraulic cylinder venting ball valve PQ straight up, water in cylinder, will be full of, close two venting ball valve PQ straight up.
6) the regulation bolt of pressure relief pilot-actuated valve XA is the most slowly rotated, gradually rise valve inlet pressure (Pressure gauge G1/G1 ' show value), observed pressure table G2/G2 ' show value simultaneously, whether at about 0.7MPa (when Pressure gauge G1/G1 ' show value is at about 1.0MPa), if pressure does not meets, please regulate the regulation bolt of decompression pilot valve JA, Pressure gauge G2/G2 ' show value will be increased clockwise, reduce Pressure gauge G2/G2 ' show value counterclockwise, locking regulation bolt and nut after regulation.
7) continuing the most slowly to rotate the regulation bolt of pressure relief pilot-actuated valve XA, gradually rise valve inlet pressure, until system pressure maintains 1.8MPa, i.e. Pressure gauge G1/G1 ' show value is when about 1.8MPa, locking regulation bolt and nut.
8) ball valve BV1 ', BV3 ' being opened, close ball valve BV3, now system pressure will be gradually lowered.The most slowly rotating the regulation bolt of pressure relief pilot-actuated valve XB, gradually rise valve inlet pressure, until system pressure maintains about 1.9MPa, i.e. Pressure gauge G1/G1 ' show value is when about 1.9MPa, locking regulation bolt and nut.
9) closing ball valve BV1, now system pressure will be gradually lowered.Inspection water in-cylinder pressure after pressure stabilisation, i.e. Pressure gauge G2/G2 ' show value, if at about 0.7MPa, Pressure gauge G2/G2 ' show value will be increased clockwise, reduce Pressure gauge G2/G2 ' show value counterclockwise, locking regulation bolt and nut after regulation.
10) opening ball valve BV1, BV3, now system pressure will be maintained at about 1.8MPa.
11) finally check that ball valve is except on water vat two in addition to venting ball valve PQ is normally closed straight up, remaining ball valve all should be normally opened, and debugging completes.
