Description

A kind of water turbine inlet butterfly valve with double containment
Technical field
A kind of water turbine inlet butterfly valve with double containment is the utility model is related to, particularly a kind of water with double containment The drive device of the valve body maintenance sealing ring of turbine water inlet butterfly valve.
Background technology
There is two seals pair in water turbine inlet butterfly valve, be the water turbine inlet butterfly valve with double containment, in butterfly valve body Upstream side have maintenance sealing pair, there is working seal pair in downstream.When working seal is secondary to be needed to safeguard or overhaul, can first by Maintenance sealing pair input reaches sealing state, secondary to working seal in the case of then not cutting off the water in upstream to carry out Maintenance and Repair work Make.
Water turbine inlet butterfly valve with double containment has a cylinder valve, and valve body front portion is delivery port, valve body rear portion be into There is a valve body working seal circle mouth of a river, the delivery port side in valve body, and the water inlet side in valve body has valve body to overhaul sealing ring, valve There is valve shaft on body, butterfly plate is connected with the valve shaft in valve body, have on butterfly plate and sealed respectively with valve body working seal circle and valve body maintenance The butterfly plate working seal circle being engaged and butterfly plate maintenance sealing ring are enclosed, there is the cylindrical shape hydraulic cylinder along valve body cylinder, circle on valve body There is circle tube piston in cylindrical hydraulic cylinder, valve body maintenance sealing ring is connected on circle tube piston.
When butterfly plate is in the closed position, sealing ring is overhauled in cylinder valve during forward and backward slip with hydraulic-driven valve body, Body movable sealing ring can be made to merge and separate with butterfly plate maintenance sealing ring, realize the closing and unlatching of maintenance sealing pair.
In the prior art, the drive device of valve body maintenance sealing ring is fluid pressure drive device, is overhauled with hydraulic-driven valve body Sealing ring needs hydraulic station, once hydraulic station is faulty, cannot realize the closing and unlatching of maintenance sealing pair.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, proposes one kind when hydraulic station is faulty, still The water turbine inlet butterfly valve with double containment of closing and the unlatching of maintenance sealing pair can be realized.
The utility model is realized with the following method.
Water turbine inlet butterfly valve with double containment has a cylinder valve, and valve body front portion is delivery port, valve body rear portion be into There is a valve body working seal circle mouth of a river, the delivery port side in valve body, and the water inlet side in valve body has valve body to overhaul sealing ring, valve There is valve shaft on body, butterfly plate is connected with the valve shaft in valve body, have on butterfly plate and sealed respectively with valve body working seal circle and valve body maintenance The butterfly plate working seal circle being engaged and butterfly plate maintenance sealing ring are enclosed, there is the cylindrical shape hydraulic cylinder along valve body cylinder, circle on valve body Have circle tube piston in cylindrical hydraulic cylinder, valve body maintenance sealing ring is connected on circle tube piston, the water inlet after valve body be connected with into Water short tube, the rear end cylinder bottom of cylindrical shape hydraulic cylinder are evenly equipped with the axis circular hole parallel with valve axis, are installed with circular hole and are connected in circle The screw putter of ring piston rear end, there is sealing ring between circular hole and screw putter, the excircle of short tube of intaking be evenly equipped with through The screw putter seat of screw putter, there is forward and backward drive nut on the screw putter of screw putter seat both sides, screw putter rear end has Pointer, there is graduated scale by the pointer of the excircle for short tube of intaking.
It is rear to slide before screw putter and forward and backward drive nut are pressed by pointer and graduated scale synchronously drives circle tube piston, It is rear to slide before sealing ring can be overhauled with moving valve, realize the closing and unlatching of maintenance sealing pair.Screw putter and forward and backward driving Nut drive is the manual auxiliary drive of the utility model valve body maintenance sealing ring.
In use, when hydraulic station energy normal work, it is rear to slide before can driving circle tube piston with hydraulic pressure, drive valve It is rear to slide before sealing ring is repaiied in physical examination, realize the closing and unlatching of maintenance sealing pair;When the faulty cisco unity malfunction of hydraulic station When, rear to slide before can driving circle tube piston with the manual auxiliary drive of valve body maintenance sealing ring, band moving valve overhauls It is rear to slide before sealing ring, realize the closing and unlatching of maintenance sealing pair.
The utility model valve body maintenance sealing ring has fluid pressure drive device and manual auxiliary drive, when hydraulic station has event When barrier, the closing and unlatching of maintenance sealing pair still can be realized.
Below in conjunction with the accompanying drawings, the utility model is further described.
Brief description of the drawings
Fig. 1 be according to scheme of the invention of the present utility model, a kind of water turbine inlet butterfly valve with double containment of proposition Schematic diagram cuts open in main view office;
Fig. 2 is enlarged diagram at Fig. 1 I;
Fig. 3 is Fig. 2 K to schematic diagram.
Embodiment
In Fig. 1 ~ Fig. 3, the water turbine inlet butterfly valve with double containment has cylinder valve 1, and valve body front portion is delivery port 2, Valve body rear portion is water inlet 3, and there is a valve body working seal circle 4 the delivery port side in valve body, and there is valve the water inlet side in valve body Sealing ring 5 is repaiied in physical examination, there is valve shaft 6 on valve body, and butterfly plate 7 is connected with the valve shaft in valve body, have on butterfly plate worked respectively with valve body it is close The butterfly plate working seal circle 8 and butterfly plate that seal and valve body maintenance sealing ring are engaged overhaul sealing ring 9, have on valve body along valve body and justify The cylindrical shape hydraulic cylinder 10 of cylinder, there is circle tube piston 11 in cylindrical shape hydraulic cylinder, and valve body maintenance sealing ring is connected in circle tube piston On, the water inlet after valve body is connected with into water short tube 12, the rear end cylinder bottom of cylindrical shape hydraulic cylinder and is evenly equipped with axis and is put down with valve axis Capable circular hole 13, the screw putter 14 for being connected in circle tube piston rear end is installed with circular hole, there is sealing between circular hole and screw putter Circle 15, the excircle for short tube of intaking is evenly equipped with the screw putter seat 16 through screw putter, and the screw thread of screw putter seat both sides pushes away There is forward and backward drive nut 17,18 on bar, there is pointer 19 screw putter rear end, has scale by the pointer of the excircle for short tube of intaking Chi 20.
