Working principle: the water supply pump 1 is installed to the one end of water supply main pipe 2, water supply pump 1 can supply water for water supply main pipe 2, water in the water supply main pipe 2 can shunt to the desuperheating water pipe 3, then these water can flow and get into in the water supply main pipe 4 through desuperheating water pipe 3, can be for the steam cooling in the water supply main pipe 4, in this process, left side block valve 6 and right block valve 7 can separate desuperheating water pipe 3 for the water in the water supply main pipe 2 can't pass through desuperheating water pipe 3, so that the steam temperature in the water supply main pipe 4 can't reduce, can also open left side block valve 6 and right block valve 7, then adjust the water flow of water supply main pipe 2 through desuperheating water pipe 3 through governing valve 5, so that the ration cooling to water supply main pipe 4 is realized.
When the main pipe 4 for supplying the cooling water is needed, the left block valve 6 and the right block valve 7 can be opened firstly, then the left adjusting shaft 10 and the right adjusting shaft 11 are respectively rotated according to the requirement and the reading of each pressure gauge, the left adjusting shaft 10 can be opened to the left hand throttle valve 8 after rotating, the right adjusting shaft 11 can be opened to the right hand adjusting valve 9 after rotating, when the internal pressure of the cooling water pipe 3 is larger, the opening speed and the amplitude of each hand throttle valve can be slowed down, thus the impact of the large pressure to the adjusting valve 5 can be effectively reduced, the adjusting precision of the adjusting valve 5 can be improved, the service life of the adjusting valve 5 can be prolonged, and when the internal pressure of the cooling water pipe 3 is smaller, the opening speed and the amplitude of each hand throttle valve can be increased, so that the working efficiency is improved.
Because the left hand throttle valve 8 and the right hand throttle valve 9 are respectively located at two sides of the regulating valve 5, if a single hand throttle valve is opened, the pressure on one side corresponding to the regulating valve 5 is suddenly increased, so that the control precision and the service life of the regulating valve 5 can be influenced for a long time, the driving belt 22 is sleeved on the surfaces of the left regulating component 12 and the regulating wheel 13, when the left regulating component 12 is rotated, the driving belt 22 is driven to synchronously rotate by the left regulating component 12, and then the driving belt 22 can drive the regulating wheel 13 to rotate, so that the left regulating shaft 10 and the right regulating shaft 11 are rotated together, and finally, the left hand throttle valve 8 and the right hand throttle valve 9 are synchronously opened, so that the two sides of the regulating valve 5 are simultaneously impacted, so that the impact forces on the two sides of the regulating valve 5 are mutually offset, the service life of the regulating valve 5 is favorably improved, and the driving belt 22 can also enable a single person to finish the synchronous operation of each hand throttle valve, so that the labor cost is reduced.
When the pressure on the left side of the left hand throttle valve 8 is smaller than the pressure on the right side of the right hand throttle valve 9, the opening amplitude of the right hand throttle valve 9 is required to be larger than that of the left hand throttle valve 8, so that the pressures on two sides of the regulating valve 5 can be balanced in the synchronous opening process of the left hand throttle valve 8 and the right hand throttle valve 9, then the constant delivery pump can be controlled to be opened according to the readings of all pressure gauges, the hydraulic medium is supplied to the supply pipe 16 through the control pipe, finally the hydraulic medium can enter the hydraulic pipe 14, the hydraulic pipe 14 is made of elastic materials, the volume of the hydraulic medium is enlarged after the hydraulic medium is supplied to the hydraulic pipe 14, the cross beam 15 is also lengthened, the diameter of the hydraulic pipe 14 cannot be enlarged due to the fact that the hydraulic pipe 14 is positioned in the middle of each telescopic sleeve 18, the diameter of the circular ring formed by the hydraulic pipe 14 is enlarged, after the circular ring formed by the hydraulic pipe 14 is enlarged, the end sections of the telescopic sleeves 18 forming the semicircular telescopic sleeves are respectively connected with the two ends of the fixed sleeves 17, the telescopic sleeves 18 are also enlarged due to the fact that the telescopic sleeves 18 are formed by the diameter of the telescopic sleeves forming the telescopic rings 13 after the telescopic sleeves are enlarged due to the fact that the telescopic rings are formed by the telescopic sleeves 13.
At this time, the handle 26 is rotated to drive the adjusting plate 25 to rotate, so that the adjusting plate 25 contacts with the fixed sleeve 17 and drives the left adjusting component 12 to rotate, and the contact between the adjusting plate 25 and the fixed sleeve 17 can ensure that the circular ring formed by each telescopic sleeve 18 of the left adjusting component 12 is not deformed by external force when rotating, thereby ensuring the transmission precision of the left adjusting component 12 to the transmission belt 22, and the contact between the adjusting plate 25 and the fixed sleeve 17 can further improve the stability of the rotating left adjusting component 12.
As can be seen from the belt drive ratio calculation formula, the ratio=drive wheel diameter: the diameter of the driven wheel is larger than that of the right adjusting wheel 13, so after the diameter of a circular ring formed by each telescopic sleeve 18 is larger than that of the right adjusting wheel 13, the transmission belt 22 can drive the right adjusting wheel 13 to rotate by more than one unit after rotating the left adjusting assembly 12 by one unit, the left manual adjusting valve 8 and the right manual adjusting valve 9 are synchronously opened, in the synchronous opening process, the opening amplitude of the right manual adjusting valve 9 is ensured to be larger than that of the left manual adjusting valve 8, the impact force born by two sides of the balanced 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 can drive the right adjusting wheel 13 to rotate in the optimal transmission ratio.
After each telescopic sleeve 18 is stretched out by the hydraulic pipe 14, the distance between two adjacent telescopic sleeves 18 can be increased, at this time, the clamping groove 19 on the surface of each telescopic sleeve 18 can be far away from each clamping piece 20 and stop after the hydraulic pipe 14 stops expanding, at this time, the movement of each telescopic sleeve 18 can also stop, the magnetic ball 21 at the front end of each clamping piece 20 can be clamped on the end face of the corresponding clamping groove 19, which faces towards one large round side of each telescopic sleeve 18, so that each telescopic sleeve 18 can be blocked by each clamping piece 20, the telescopic sleeves 18 are prevented from retracting, and the strength of a round ring formed by the telescopic sleeves 18 is ensured during transmission.
Meanwhile, the clamping groove 19 and the clamping piece 20 are only arranged on one side close to the axis of the left adjusting shaft 10, and the adjusting plate 25 is also arc-shaped, so that the left adjusting component 12 and the driving belt 22 have enough contact area to ensure the accuracy of driving.
When the pressure on the left side of the left hand throttle valve 8 is larger than the pressure on the right side of the right hand throttle valve 9, the opening amplitude of the left hand throttle valve 8 is required to be smaller than the opening amplitude of the right hand throttle valve 9, the quantitative 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 the moment, the volume of the hydraulic medium in the hydraulic pipe 14 is reduced, meanwhile, the hydraulic pipe 14 is made of elastic materials, the diameter of a circular ring formed by the hydraulic pipe 14 is reduced, 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 drives the rotation shaft 24 and the regulating plate 25 at the front end of the rotation shaft to rotate together, and the regulating plate 25 is made of magnetic materials, and each card 20 all faces the axis of telescopic shaft 18, therefore it can produce the suction with each magnetic ball 21, and inhale the magnetic ball 21 to the one side of keeping away from telescopic shaft 18 axis, at this moment each card 20 and magnetic ball 21 will laminate the inner wall of telescopic sleeve 18, no longer provide support for draw-in groove 19, thereby make each telescopic sleeve 18 can shrink under the drive of shrink hydraulic pipe 14 together, reduce the ring diameter that telescopic sleeve 18 formed, the same can know according to the transmission ratio formula of belt drive, left side adjusting component 12 diameter is less than right side adjusting wheel 13 diameter after, the opening range of left hand throttle valve 8 will be less than right hand throttle valve 9, in order to balance the impact dynamics that adjusting valve 5 both sides received.
