Description
Technical field
The utility model relates to a kind of gate valve, relates in particular to a kind of gate valve of fast opening and closing.
Background technique
In the pipe-line system of conveyance fluid medium, gate valve is the most frequently used valve of making the control media break-make.The gate valve that uses now is from the full cut-off to the standard-sized sheet both at home and abroad, flap needs lift stroke to equal the latus rectum of valve, be also referred to as bore, adopt the lifting of bolt rod driving valve flap, the number of turns=latus rectum/screw pitch of rotating of screw rod then is as DN100 gate valve: latus rectum=100mm, drive screw pitch=4mm, the number of turns that screw rod rotates during valve opening and closing=100mm ÷ 4mm=25 circle, operation was both wasted time and energy, but also influence utilize valve pilot line system process parameter accurately.
Summary of the invention
But the purpose of this utility model provides a kind of gate valve of fast lifting, to solve the defective of above-mentioned prior art.
The utility model is achieved in that a kind of fast opening and closing gate valve, comprise: valve body, flap, can drive the valve rod of flap lifting, and the device of drive valve rod lifting, flap is located on the overflow section of valve inner, on the overflow section of valve body, also respectively be provided with the logical grid of valve body of the identical permission overcurrent in some cross sections and do not allow the valve body of overcurrent to end grid, on flap, also respectively be provided with the logical grid of flap of the identical permission overcurrent in some cross sections and do not allow the flap of overcurrent to end grid, flap ends the residing overflow section of grid and is positioned at the downstream that valve body ends the residing overflow section of grid, and spacing is the thickness that valve body ends grid, but described flap ends the front end surface of grid and the rear end surface close fit that valve body ends grid.
Flap only need promote the height that a flap ends grid and just can realize overcurrent or choked flow like this, has therefore just finished keying in very short stroke, and has not influenced flow, makes the simple and easy and leicht fallen D/A of operation.

Embodiment
The quick gate valve of the utility model comprises handwheel 1 as shown in Figure 1, valve rod 2, flap 3, valve body 4, valve rod 2 is fixedlyed connected with flap 3 and is embedded in valve body 4 inside, it is outer and can drive with it by fixedly connected valve rod 2 liftings of screw cap 5 that handwheel 1 is positioned at valve body 4, valve rod 2 can drive flap 3 liftings, between the surface of contact of valve rod 2 and valve body 4, be provided with dirt-proof boot 6 successively, seal ring 7, separation sleeve 8, to prevent that valve rod 2 from damaging because of friction, also avoid owing to dust fall results in blockage simultaneously, the big both sides of the middle latus rectum latus rectum of valve body 4 is little, the flaring angle that the minimum place of the latus rectum biggest place of described valve body 4 and latus rectum constitutes, taper angle is 25 degree, the vortex phenomenon and the noise phenomenons that can reduce or avoid causing because of overcurrent like this.The latus rectum of valve body 4 is minimum to be located to inflow port or goes out head piece to be called valve 14.Described flap 3 is located on the overflow section of latus rectum biggest place of valve body 4 inside, on the overflow section of valve body 4, also respectively be provided with the logical grid 9 of valve body of the identical permission overcurrent of some height and do not allow the valve body of overcurrent to end grid 10, also respectively being provided with some and valve body on flap 3 ends the logical grid 12 of flap of the highly identical permission overcurrent of grid 10 and does not allow the flap of overcurrent to end grid 11, described valve body leads to grid 9, the logical grid 12 of flap are all hollow, valve body ends grid 10, flap ends grid 11 and is the horizontal stripe grid, flap ends grid 11 residing overflow sections and is positioned at the downstream that valve body ends grid 10 residing overflow sections, and spacing is the thickness that valve body ends grid 10, but flap ends the front end surface of grid 11 and the rear end surface close fit that valve body ends grid 10, so just can guarantee its sealing, be that current can not pass through, end at flap and also to be provided with some valve bodies on the overflow section that the downstream of grid 11 residing overflow sections and spacing are the flap thickness that ends grid 11 and to end grid 10, but described valve body ends the front surface of grid 10 and rear end surface that flap ends grid 11 and close fit, being in conplane two valve bodies ends 10 of grid and can hold a flap just and end grid 11, described valve body ends grid 10, it is trapezoid shaped that flap ends grid 11 its longitudinal sections perpendicular to overflow section, when valve body 4 is close valve state, between the top of flap 3 and valve body 4, leave a volume and equal the gap 13 that valve body ends grid 10 volumes, described flap ends grid 11 and is positioned on the identical plan-position with the logical grid 9 of corresponding valve body, make originally can overcurrent the logical grid 9 of valve body ended grid 11 by flap that can not overcurrent and substitute, close the purpose that valve stops overcurrent thereby reach, because valve body ends grid 10, it is that this structure of trapezoid shaped makes valve body end grid 10 and flap ends better tightness between the grid 11 that flap ends grid 11 its longitudinal sections perpendicular to overflow section, purpose that two valve bodies end grid 10 is set also is for sealing more to prevent leakage current.
As shown in Figure 2: valve rod 2 is risen when rotating handwheel 1, valve rod 2 drives flaps 3 and moves upward a valve body when ending grid 10 height, flap 3 tops just contact with valve body 4, and can not move upward again, at this moment, flap ends grid 11 and is in corresponding two valve bodies and ends 10 of grid, the logical grid 9 of valve body overlap with the logical grid 12 of corresponding flap, make fluid to flow through in the logical grid and reach the purpose of overcurrent, make the latus rectum of the height summation of the logical grid 9 of valve body more than or equal to valve 14 by the length that valve body 4 is set, total like this area of passage still equals the valve area.
As shown in Figure 3: valve 14 be square in rounded on the overflow section, valve body 4 its upper end on overflow section, and the lower end is a semicircle, so just can guarantee that the length that flap ends grid 11 is not more than the length that corresponding valve body ends grid 10.
Certainly; described valve body ends grid, flap, and to end grid also can be other shape except the horizontal stripe grid; as the arcuation grid; described valve rod also can be for being located at the rising stem (RS.) of valve body outside; described handwheel also available motor substitutes; flaring angle, taper angle also are provided with can be in certain scope, and as 20 °-30 °, attainable simple structure conversion all drops in the protection domain of the present utility model all technician without creative work.
