When supplying the desuperheating water at the female pipe 4 of steam supply, can open left block valve 6 and right block valve 7 at first, according to the reading of demand and each manometer afterwards, rotate left regulation axle 10 and right regulation axle 11 respectively, left regulation axle 10 rotates the back and can open left hand throttle valve 8, right regulation axle 11 rotates the back and can open right hand regulating valve 9, when 3 internal pressure of desuperheating water pipe is great, can slow down the opening speed and the range of each hand throttle valve, can effectively reduce the impact of big pressure to regulating valve 5 like this, thereby improve regulating valve 5's regulation precision, can also improve regulating valve 5's life, when 3 internal pressure of desuperheating water pipe is less, then opening speed and the range of multiplicable each hand throttle valve, with this improvement work efficiency.
Because the left manual throttle valve 8 and the right manual throttle valve 9 are respectively located at two sides of the regulating valve 5, if a single manual throttle valve is opened, the pressure received by one side corresponding to the regulating valve 5 is suddenly increased, so that great impact is caused to the regulating valve 5, and the control accuracy and the service life of the regulating valve 5 are affected in the past, therefore, a transmission belt 22 is sleeved on the surface of the left regulating assembly 12 and the surface of the regulating wheel 13, when the left regulating assembly 12 is rotated, the left regulating assembly 12 can drive the transmission belt 22 to synchronously rotate, then the transmission belt 22 can drive the regulating wheel 13 to rotate, so that the left regulating shaft 10 and the right regulating shaft 11 rotate together, and finally the left manual throttle valve 8 and the right manual throttle valve 9 are synchronously opened, so that two sides of the regulating valve 5 are simultaneously impacted, so that the impact forces at two sides of the regulating valve 5 are mutually offset, and the service life of the regulating valve 5 is favorably prolonged, and the transmission belt 22 can also enable a worker to complete the synchronous operation of each manual throttle valve by a single person, so that the labor cost is reduced.
When the pressure on the left side of the left-hand-operated throttle valve 8 is smaller than the pressure on the right side of the right-hand-operated throttle valve 9, the opening range of the right-hand-operated throttle valve 9 needs to be larger than the opening range of the left-hand-operated throttle valve 8, so that in the synchronous opening process of the left-hand-operated throttle valve 8 and the right-hand-operated throttle valve 9, the pressures on the two sides of the balance regulating valve 5 can be balanced, then the quantitative pump can be controlled to be opened according to the reading of each pressure gauge, and the hydraulic medium is supplied to the supply pipe 16 through the control pipe, finally the hydraulic medium can enter the hydraulic pipe 14, because the hydraulic pipe 14 is made of elastic material, the volume of the hydraulic medium supplied into the hydraulic pipe 14 can be increased, meanwhile, the cross beam 15 can be extended, because the hydraulic pipe 14 is positioned in the middle of each telescopic sleeve 18, the diameter of the hydraulic pipe 14 cannot be increased, the diameter of a circular ring formed by the hydraulic pipe 14 can be increased, and the diameter of the circular ring formed by the hydraulic pipe 14 can be increased, because the head and tail sections of the semi-circular telescopic sleeves 18 are respectively connected with the two ends of the fixed sleeve 17, and the fixed sleeve 17 can move outwards along with the extension of the cross beam 15, the diameter of the circular ring formed by each telescopic sleeve 18 after the diameter of the circular ring formed by the hydraulic pipe 14 becomes larger can be synchronously expanded, so that the diameter of the circular ring formed by each telescopic sleeve 18 is larger than the diameter of the right regulating wheel 13.
At this moment, the rotating handle 26 drives the adjusting plate 25 to rotate, the adjusting plate 25 is in contact with the fixing sleeve 17 and drives the left adjusting assembly 12 to rotate, and through the contact between the adjusting plate 25 and the fixing sleeve 17, the ring formed by each telescopic sleeve 18 when the adjusting assembly 12 rotates can be ensured not to be deformed by external force, so that the transmission precision of the left adjusting assembly 12 to the transmission belt 22 is ensured, and the stability of rotating the left adjusting assembly 12 can be improved due to the contact between the adjusting plate 25 and the fixing sleeve 17.
As can be seen from the belt drive ratio calculation formula, the drive ratio is the diameter of the capstan: the diameter of the driven wheel is larger than that of the right adjusting wheel 13, and after the diameter of a circular ring formed by each telescopic sleeve 18 is larger than that of the right adjusting wheel 13 and one unit of left adjusting assembly 12 is rotated, the transmission belt 22 can drive the right adjusting wheel 13 to rotate by more than one unit, so that the left manual adjusting valve 8 and the right manual adjusting valve 9 are synchronously opened, and in the synchronous opening process, the opening amplitude of the right manual adjusting valve 9 is larger than that of the left manual adjusting valve 8, so that the impact force received by two sides of the balance adjusting valve 5 is achieved, and the diameter of the circular ring formed by each telescopic sleeve 18 can be adjusted according to the reading of each pressure gauge, so that the left adjusting assembly 12 is ensured to drive the right adjusting wheel 13 to rotate with the optimal transmission ratio.
After each telescope tube 18 is propped open by hydraulic pressure pipe 14, the distance between two adjacent telescope tubes 18 can increase, draw-in groove 19 on telescope tube 18 surface this moment can keep away from each card 20 and remove, and stop after hydraulic pressure pipe 14 stops the inflation, the removal of telescope tube 18 also can stop this moment, the magnetic ball 21 of card 20 front end can block on the terminal surface of corresponding draw-in groove 19 towards telescope tube 18 great circle one side, make telescope tube 18 can be blockked by each card 20, prevent that telescope tube 18 from retracting, thereby make the ring that telescope tube 18 formed guarantee self intensity when the transmission.
Meanwhile, the clamping groove 19 and the clamping piece 20 are only arranged on one side close to the axle center of the left adjusting shaft 10, and the adjusting plate 25 is also arc-shaped, so that the left adjusting component 12 and the transmission belt 22 have enough contact area to ensure the transmission precision.
When the pressure on the left side of the left-hand throttle valve 8 is greater than the pressure on the right side of the right-hand throttle valve 9, the opening range of the left-hand throttle valve 8 needs to be smaller than the opening range of the right-hand throttle valve 9, the constant delivery pump can be controlled to pump out a part of the hydraulic medium in the supply pipe 16 and the hydraulic pipe 14 through the control pipe, at this time, the volume of the hydraulic medium in the hydraulic pipe 14 will be reduced, meanwhile, the diameter of a circular ring formed by the hydraulic pipe 14 will be reduced because the hydraulic pipe 14 is made of elastic material, then the handle 26 is rotated, the rotation direction of the handle 26 is consistent with the orientation of each card 20, the handle 26 will drive the rotating shaft 24 and the adjusting plate 25 at the front end to rotate together, because the adjusting plate 25 is made of magnetic material, and each card 20 faces the axis of the telescopic shaft 18, it will generate suction with each magnetic ball 21 and suck the magnetic ball 21 to the side away from the axis of the telescopic shaft 18, at this moment, each card 20 and the magnetic ball 21 will be attached to the inner wall of the telescopic sleeve 18, no longer provide support for the clamping groove 19, thereby enabling each telescopic sleeve 18 to be contracted together under the driving of the contracted hydraulic pipe 14, reducing the diameter of a circular ring formed by the telescopic sleeve 18, and similarly, knowing according to a transmission ratio calculation formula of belt transmission, after the diameter of the left adjusting component 12 is smaller than the diameter of the right adjusting wheel 13, the opening amplitude of the left hand-operated throttle valve 8 will be smaller than the opening amplitude of the right hand-operated throttle valve 9, and balancing the impact force received by two sides of the adjusting valve 5.
