Embodiment
Below in conjunction with accompanying drawing a kind of high-pressure water low pressure hydraulic control switch valve of the present utility model is described in detail.
With reference to accompanying drawing 1, described switch valve is by valve body 11, and valve seat 6 and valve rod 9 constitute, and at the valve body front end first blanking cover 1 are arranged, on valve body 11 by intake pipe flange 2 and outlet pipe flange 26 respectively fixedly the high pressure water inlet take over 3 and take over 28 with the high pressure water outlet.And between water inlet adapter 3 and water outlet adapter 28 and valve body 11, be respectively arranged with influent side seal ring 4 and water outlet side seal ring 27.The tail end of valve rod 9 is connected with the piston rod end of a hydraulic jack by connecting sleeve 15.
High-pressure water is through water inlet adapter 3, influent side seal ring 4, first setting sleeve 5, valve body 11, valve seat 6, second setting sleeve 7, stuffing box gland 8, water outlet side seal ring 27, water outlet adapter 28 and valve rod 9 are formed the ultrahigh pressure water cavity of sealing, and it will tolerate the hydraulic pressure intensity of 100Mpa.The oil-feed of oil cylinder right oil port promotes valve rod 9 and is moved to the left, and makes the conical surface and the sealing of valve seat 6 sealing strips of valve rod 9, and import and export high-pressure water and close this moment.Oil cylinder left oil port oil-feed pulling valve rod 9 moves right, and the conical surface of valve rod 9 is separated with valve seat 6 sealing strips, and import and export high-pressure water and open this moment.Reached the switching function of high-pressure water.
Valve rod 9 sealed ends are provided with balancing orifice to the valve rod middle part, second blanking cover 10, the 3rd setting sleeve 12, second stuffing box gland 13, valve rod 9 compositions are all pressed the chamber, as long as make oil cylinder that little thrust be arranged, just can guarantee the sealing of valve rod 9, valve seat 6, and only need the hydraulic coupling of 1Mpa can make the flexible opening and closing of switch valve.Realized the purpose of low pressure hydraulic control.Left side cylinder cap 17, piston unt 18, piston 19, cylinder barrel 20, right side cylinder cap 21, piston rod 22 are formed hydraulic jacks, by pull bar 14, supporting sleeve 16 hydraulic jack are fixed on the valve body.By connecting sleeve 15 piston rod is connected with valve rod.
Oil cylinder of the present utility model adopts two oil cylinders of lifting one's head, one end piston rod of described oil cylinder is connected with valve rod 9, the other end connects switch collision block 25, oil cylinder right side cylinder cap 21 is equipped with position limit switch seat 23 and position limit switch 24, it forms the utility model switched electrical signal feedback mechanism, can make the utility model obtain effectively control and telecontrol automatically.
