Embodiment
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
With reference to Fig. 1, the present embodiment provides a kind of manual diaphragm type cylinder body combination normally open valve door, comprises valve body 2, valve body 2 be provided with the water intake 2-1 of level and with the vertically disposed water outlet 2-6 of water intake 2-1, valve body 2 water intake 2-1 places are provided with import interface 2-2; Diaphragm type cylinder body 1 is positioned at valve body 2 tops, and between diaphragm type cylinder body 1 and valve body 2, by screwed connection and sealing, diaphragm type cylinder body cuts off into epicoele 1-2 and cavity of resorption 1-7 through diaphragm 1-9, and the cavity of resorption of diaphragm type cylinder body is provided with cavity of resorption interface 1-8; The epicoele of diaphragm type cylinder body is provided with epicoele interface 1-1; Valve rod 2-5 through cut off body 2-3 and and cut off slipper seal body 2-3; In position, described valve rod 2-5 top diaphragm type cylinder body 1; Diaphragm 1-9 is fixed on valve rod 2-5 top by membranous disc 1-10 and hold down gag 1-3, and diaphragm 1-9 periphery is clipped between epicoele 1-2 and cavity of resorption 1-7, and by screw fixing seal; Between cavity of resorption 1-7 and diaphragm hold down gag 1-3, be provided with spring 1-6; Diaphragm 1-9 internal diameter in diaphragm type cylinder body 1 is greater than the internal diameter of water intake 2-1.The withstand voltage pliable and tough thing that diaphragm 1-9 becomes for folder fabric rubber.Cut off between body 2-3 and membranous disc 1-9 and be provided with guide cup 1-5, spring 1-6 one end is positioned at guide cup 1-5.Cut off between body 2-3 and membranous disc 1-9 and be provided with guide cup 1-5, spring 1-6 one end is positioned at guide cup 1-5.Between hold down gag 1-3 and diaphragm 1-9, be provided with positive stop cup 1-4.Guide cup 1-5 and positive stop cup 1-4 side are provided with thin discharge orifice, are convenient to the inside and outside liquid communication of positive stop cup.The control loop 3-1 that passes through of two-position four-way hand-operated direction valve 3 connects respectively import interface 2-2, epicoele interface 1-1, cavity of resorption interface 1-8 and water tank.
In the time of valve opening, import interface 2-2 and cavity of resorption interface 1-8 form the loop that communicates; Described epicoele interface 1-1 becomes dump circuit with water tank shaped.
Now, the pressure P that epicoele 1-2 produces diaphragm 1-9
on=0.The pressure P that cavity of resorption 1-7 produces diaphragm 1-9
under, diaphragm 1-9 is also subject to the tension force P of spring 1-6 simultaneously

Work as valve closing, operation two-position four-way hand-operated direction valve 3 makes import interface 2-2 and epicoele interface 1-1 form the loop that communicates; Described cavity of resorption interface 1-8 becomes dump circuit with water tank shaped.
Now, the pressure P that cavity of resorption 1-7 produces diaphragm 1-9
under=0.The pressure P that epicoele 1-1 produces diaphragm 1-9
onwith the pressure P of the 2-1 of inlet to spool 2-9 generation
coreacting in conjunction overcomes the tension force P of spring 1-6
bulletthereby, make the spool 2-9 of valve at diaphragm 1-9 effect throttle down.And while closing, sealability is along with the pressure of pipeline increases, airtight performance strengthens.
This valve mechanism is simple, and cost of production is low; Under normal circumstances, the opening force of valve is more than or equal to the tension force of spring 1-6 to this valve, all the time in opening state, and irrelevant with pipeline pressure size; When valve closing, sealability is along with the pressure of pipeline increases, and airtight performance strengthens; This valve can be in a state of often opening simultaneously.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
