Example (b):

referring to fig. 1-5, the present invention provides a technical solution: a hydraulic transmission water valve for preventing backwater comprises a valve body 1, wherein joints 2 are arranged on the front side and the rear side of the valve body 1, when the valve is used, the joints 2 on the two sides are respectively connected with an external pipeline, guide pipes 5 extending to the inner side of the valve body 1 are arranged on the inner sides of the joints 2 on the two sides, single through pipes 4 are connected between the guide pipes 5 on the two sides, the number of the single through pipes 4 is two, a one-way valve 7 and an adjusting valve 8 are arranged on the body of the single through pipe 4, through the limitation of the one-way valve 7, fluid can only pass through one single through pipe 4 once, when the fluid enters from the joint 2 on the front side, the fluid flows through the single through pipe 4 on the front side, the single through pipe 4 on the rear side cannot flow, otherwise, when the fluid enters from the joint 2 on the rear side, the fluid can only flow through the single through pipe 4 on the rear side, the adjusting valve 8 is communicated with the other single through pipe 4 through a pipeline, fluid entering the regulating valve 8 through another single-way pipe 4 can move through the hydraulic pressure pushing valve core 810, the regulating valve 8 comprises a shell 820, the valve core 810 is movably installed in an inner cavity of the shell 820, a return spring 830 is connected between one side of the valve core 810 and the inner cavity wall of the shell 820, when the fluid in the single-way pipe 4 flows away, the return spring 830 can push the valve core 810 to return, the valve core 810 comprises a sealing core 811, firstly, the sealing core 811 can avoid fluid streaming between the two single-way pipes 4, secondly, after the sealing core 811 enters the single-way pipe 4, the single-way pipe 4 can be closed through blocking of the sealing core 811, a convection core 812 is connected between the sealing core 811 and the return spring 830, a convection hole is formed in the body of the convection core 812, and after the convection core 812 enters the single-way pipe 4, the fluid can pass through the convection hole, so that the single-way pipe 4 is opened.

Be provided with spacing ring 821 in the inner chamber of shell 820, spacing ring 821 is located reset spring 830's the outside, carries on spacingly through spacing ring 821 to case 810, when case 810 displacement is too big, case 810 and single-pass tube 4 can not want to intersect, two single-pass tubes 4 can communicate through shell 820 this moment, and the existence of spacing ring 821 for the displacement of case 810 is limited, thereby makes case 810 intersect with single-pass tube 4 all the time, and then gets two single-pass tubes 4 and can not communicate each other.

The outside that both sides connect 2 all is provided with the screw thread, can make things convenient for joint 2 and external pipe connection through the screw thread.

The honeycomb duct 5 of both sides has buffer tube 6 through the pipe connection respectively, because check valve 7 is when closing, form the water hammer effect easily, consequently, need a buffer area to cushion, thereby avoid check valve 7 and governing valve 8 to receive great impact force, the other end of both sides buffer tube 6 all is connected with transition pipe 10, the other end of both sides transition pipe 10 all is connected with hydraulic pressure pipe 9, the inboard of hydraulic pressure pipe 9 is provided with hydraulic oil, be provided with piston 13 in the inner chamber of hydraulic pressure pipe 9, the activity is provided with sealing plug 11 in the inner chamber of transition pipe 10, be connected with guide bar 12 between sealing plug 11 and the piston 13, when the pressure of fluid increases suddenly, fluid pressure can promote sealing plug 11 to remove, sealing plug 11 promotes piston 13 through guide bar 12 and removes, piston 13 extrudes hydraulic oil through removing, realize the buffering, when the fluid is steady, hydraulic oil promotes piston 13 to reset, piston 13 promotes sealing plug 11 through guide bar 12 to reset, hydraulic pressure pipe 9 is located the top of honeycomb duct 5, like this when there is no fluid in honeycomb duct 5, the fluid in 6 can be discharged under the action of gravity.

Both sides hydraulic pressure pipe 9 intercommunication each other can reduce the volume of hydraulic pressure pipe 9 on the one hand like this to reduce the quantity of hydraulic oil, the buffer area of two one-way pipes 4 of on the other hand can share, also can increase piston 13's stroke, thereby makes piston 13 when pressurized, has longer buffering line, and then improves buffering effect.

The downside of valve body 1 is provided with fixed plate 3, has seted up the through-hole on the body of fixed plate 3, runs through the through-hole of trading fixed plate 3 through the bolt, can fix this device.

The working principle is as follows: when fluid enters from the front-side connector 2, the fluid sequentially passes through the front-side flow guide pipe 5, the front-side one-way pipe 4, the front-side regulating valve 8, the front-side check valve 7 and the rear-side flow guide pipe 5, when the fluid enters the front-side one-way pipe 4, the pressure of the fluid pushes the valve core 810 of the rear-side regulating valve 8 to move towards the return spring 830, at the moment, the sealing core 811 of the valve core 810 enters the one-way pipe 4, the one-way pipe 4 is sealed, when the fluid stops injecting, the front-side one-way pipe 4 is blocked by the front-side one-way valve 7 and does not return, and the rear-side one-way pipe 4 is blocked by the sealing core 811 of the rear-side regulating valve 8 and does not return;

when fluid backflow is needed, the hydraulic pressure in the front side draft tube 5 is firstly reduced, at the moment, the return spring 830 of the rear side adjusting valve 8 releases elastic potential energy to push the valve core 810 to move, after the convection core 812 of the valve core 810 enters the single-pass tube 4, the rear side single-pass tube 4 is opened, and at the moment, the circulation flows back through the rear side draft tube 5, the rear side single-pass tube 4, the rear side adjusting valve 8, the rear side check valve 7 and the front side draft tube 5 in sequence.
