Description

Force Double-sealing plate sluice valve
Technical field
The present invention relates to valve technology field, more specifically for, it is more particularly to a kind of to force Double-sealing plate sluice valve.
Background technology
Existing flat gate valve during being turned on and off, particularly during unlatching, due to pressure medium, it is necessary to The valve opening power of application is big, so as to cause stem diameter and handwheel enlarged diameter to cause waste, it is therefore desirable to which this is changed Enter.
The content of the invention
In view of the foregoing, it is an object to provide a kind of pressure Double-sealing plate sluice valve, existing for solving Technology middle plateform gate valve needs the valve opening power applied big when opening, and then causes stem diameter and handwheel enlarged diameter to be made Into the problem of waste.
In order to achieve the above objects and other related objects, the present invention provides following technical scheme:
One kind forces Double-sealing plate sluice valve, and it includes valve body, valve seat, flashboard, valve rod, bonnet, support, handwheel, valve Filler chamber, valve seat is divided into two, and is vertically spaced arranged in the cavity of valve body, and flashboard is arranged between two valve seats, valve rod One end be connected with flashboard, the other end of valve rod is connected by valve packing room and support with handwheel, wherein, the flashboard includes Main gate-board and auxiliary gate-board, the main gate-board and auxiliary gate-board are connected by spring carrier arm, and master is fixed at the two ends of spring carrier arm On the outer surface of flashboard, it is fixed in the middle part of spring carrier arm on the outer surface of auxiliary gate-board, when gate valve is closed, the flashboard includes Main gate-board and auxiliary gate-board are merged into a rectangular flat.
Preferably, main gate-board is trapezoidal flat board, and auxiliary gate-board is also trapezoidal flat board;When gate valve is closed, the flashboard includes Main gate-board and auxiliary gate-board are merged into a rectangular flat.
Preferably, main gate-board is provided with the first fixture and the second fixture, and auxiliary gate-board is provided with the 3rd fixture, first Not on the same line, the first end of spring carrier arm is fixed on the first fixture for fixture, the second fixture and the 3rd fixture On, the second end of spring carrier arm is fixed on the second fixture, and the 3rd fixture is bypassed in the middle part of spring carrier arm and institute is fixed on State on the 3rd fixture.
Beneficial effect:Above-mentioned pressure Double-sealing plate sluice valve employs the master/slave flashboard structure with incline configuration of uniqueness, Master/slave flashboard is brought into close contact in the presence of pre-pressure of the spring, and its sealing surface is parallel with sealing surface of seat, in valve opening and closing process In be not in occlusion between flashboard, sealing surface of seat.In valve opening, master/slave flashboard combination thickness is thinning, discharges simultaneously The pretightning force of valve seat, valve opening power is small;When valve is closed, master/slave flashboard thickness to thicken direction change and produce to valve The thrust of seat, when auxiliary gate-board is closed in place, continues to close main gate-board, at this moment relative displacement generation on master/slave flashboard inclined-plane Axial thrust increases, and positive closing power is produced to valve, so that reach valve is fully sealed performance.
Brief description of the drawings
Scheme in order to illustrate the embodiments of the present invention more clearly, will make to required described in specific embodiment below Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for For those skilled in the art, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other attached Figure.
Fig. 1 is a kind of a part of sectional schematic of pressure Double-sealing plate sluice valve.
Fig. 2 is the structure principle chart of main gate-board and auxiliary gate-board in the present invention.
Fig. 3 is a kind of another part sectional schematic of pressure Double-sealing plate sluice valve.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Base In embodiments of the invention, those of ordinary skill in the art obtained on the premise of creative work is not made it is all its Its embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1, present embodiments provide it is a kind of force Double-sealing plate sluice valve, as shown in figure 1, it include valve body 1, Valve seat 2, valve rod 6, bonnet 7, support 8, handwheel 9, valve packing room 10, wherein, valve seat is divided into two, and vertically spaced sets In in the cavity of valve body, flashboard is arranged between two valve seats, and one end of valve rod is connected with flashboard, and the other end of valve rod passes through valve Filler chamber and support are connected with handwheel, wherein, the flashboard includes main gate-board 5 and auxiliary gate-board 3, the main gate-board 5 and auxiliary gate-board 3 It is connected by spring carrier arm 4, the two ends of spring carrier arm 4 are fixed on the outer surface of main gate-board 5, the middle part of spring carrier arm 4 On the outer surface for being fixed on auxiliary gate-board 3, when gate valve is closed, the flashboard includes main gate-board 5 and auxiliary gate-board 3 is merged into a rectangle Flat board.
Specifically, above-mentioned pressure Double-sealing plate sluice valve is connected on pipeline and plays on-off action.The lifting of handwheel valve rod is rotated, Valve rod drives flashboard lifting to reach valve opening and the function of closing.
Wherein, Fig. 2 is seen, main gate-board 5 is trapezoidal flat board, and auxiliary gate-board 3 is also trapezoidal flat board;When gate valve is closed, the lock Plate includes main gate-board 5 and auxiliary gate-board 3 is merged into a rectangular flat.
Wherein, main gate-board 5 is provided with the first fixture and the second fixture, and auxiliary gate-board 3 is provided with the 3rd fixture, first Not on the same line, the first end of spring carrier arm 4 is fixed on the first fixture for fixture, the second fixture and the 3rd fixture On, the second end of spring carrier arm 4 is fixed on the second fixture, and the middle part of spring carrier arm 4 bypasses the 3rd fixture and is fixed on On 3rd fixture.
Above-mentioned pressure Double-sealing plate sluice valve employs the master/slave flashboard structure with incline configuration of uniqueness, master/slave flashboard It is brought into close contact, its sealing surface is parallel with sealing surface of seat, will not goes out during valve opening and closing in the presence of pre-pressure of the spring Existing occlusion between flashboard, sealing surface of seat.In valve opening, master/slave flashboard combination thickness is thinning, while discharging the pre- of valve seat Clamp force, valve opening power is small;When valve is closed, master/slave flashboard thickness to thickening direction change and produce to the thrust of valve seat, When auxiliary gate-board is closed in place, continue to close main gate-board, the axial thrust that at this moment relative displacement is produced on master/slave flashboard inclined-plane increases Greatly, positive closing power is produced to valve, so that reach valve is fully sealed performance.
