Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to Fig. 1 ~ 5, in the embodiment of the present invention, a kind of ball valve preventing switch excessive, comprises valve body 1, spheroid 2, valve gap 3, handle 6 and valve rod 7; Described valve gap 3 is bolted on valve body 1, valve body 1 comprises valve channel 9 and valve pocket 10, spheroid 2 is arranged in valve pocket 10, offer the spheroid passage 8 corresponding with valve channel 9 in spheroid 2, valve rod 7 is fixed on spheroid 2 upper end, and valve rod 7 is provided with pin rod 5, corresponding restraining groove 4 is offered in valve gap 3, pin rod 5 is in restraining groove 4, and restraining groove 4 limits the rotation angle of pin rod 5, and restraining groove 4 is fan-shaped restraining groove;
Described spheroid 2 is provided with valve seat 13 with the contact position of valve body 1, valve seat 13 and the surface of contact of valve body 1 offer seal groove, seal ring 14 is provided with in seal groove, seal ring 14 can strengthen the sealing between valve seat 13 and valve body 1, seal ring 14 is abrasive rubber seal ring, valve seat 13 is provided with belleville spring 12 and packing ring 11 away from the side of spheroid 2, belleville spring 12 is between valve seat 13 and packing ring 11, belleville spring 12 pairs of valve seats 13 are afterburning towards the direction of spheroid 2, make valve seat 13 and spheroid 2 close contact, valve body 1 is offered the mounting groove installing packing ring 11 and belleville spring 12,
Described spheroid 2 bottom welding connecting rod 15, connecting rod 15 lower end welding block plate 16, valve body 1 inner bottom offers the groove corresponding with block plate 16, on block plate 16, symmetry offers 2 breach 19, the apocenosis passage 17 corresponding with breach 19 is offered bottom valve body 1, apocenosis passage 17 bottom is provided with Air Filter 18, and Air Filter 18 prevents dust from entering apocenosis passage 17, affects proper drainage effect; Described handle 6 is bolted on valve rod 7 top.
Working principle of the present invention is: described in prevent switch excessive ball valve, by arranging pin rod 5 on valve rod 7, offer corresponding restraining groove 4 in valve gap 3, pin rod 5 is in restraining groove 4, when opening or close ball valve, pin rod 5 rotates along with the rotation of valve rod 7, when the boundary of restraining groove 4 encountered by pin rod 5, ball valve just cannot be rotated further, and now ball valve is in standard-sized sheet or full off state, thus prevent ball valve switch not in place, make the convenient position reaching standard-sized sheet or complete shut-down accurately of ball valve;
The described ball valve preventing switch excessive, owing to being provided with seal ring 14 between valve seat 13 and valve body 1, thus make to be formed between valve seat 13 and valve body 1 and seal reliably, prevent due to wearing and tearing or corrosion etc., between valve seat 13 and valve body 1, there is gap and produce leakage phenomenon, by arranging belleville spring 12, to spheroid 2 direction, valve seat 13 is exerted a force, make valve seat 13 and spheroid 2 close contact all the time, even if wearing and tearing appears because of Long-Time Service in spheroid 2 and valve seat 13, also spheroid 2 and valve seat 13 close contact can be ensured, do not make leak of liquid, packing ring 11 can when belleville spring 12 be subject to excessive power, stop that belleville spring 12 is out of shape further and overturns, ensure the normal effect of belleville spring 12,
The described ball valve preventing switch excessive, when ball valve is opened, breach 19 and the apocenosis passage 17 of block plate 16 stagger, block plate 16 blocks apocenosis passage 17, thus when ball valve is opened, liquid medium in ball valve can not flow out from apocenosis passage 17, when ball valve ends, the breach 19 of block plate 16 is positioned at above apocenosis passage 17, apocenosis passage 17 is communicated with valve pocket 10, liquid medium remaining in valve pocket 10 flows out from apocenosis passage 17, thus make ball valve can not solidify because of the liquid medium in valve pocket 10 at cold snap and be frozen in, and greatly reduce the time of spheroid 2 liquid body dielectric corrosion, extend the working life of ball valve.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present invention.As long as any improvement do the present invention or modification all belong within the protection domain of the claims in the present invention opinion.
