Abstract
The utility model discloses a self-sealing pressure type stop valve with double valve clacks. The self-sealing pressure type stop valve is composed of a valve body, a large valve clack, a small valve clack, a valve rod, a valve cover and a support, wherein one end of the valve rod penetrates through a valve rod nut on the support and is connected with a hand wheel, the other end of the valve rod penetrates through the valve cover and is connected with the small valve clack and the large valve clack, a packing seat, a packing, a spacer ring and a packing bushing are sequentially arranged between the valve cover and the valve rod from bottom to top, a packing pressure plate is arranged on the packing bushing, wedge-shaped sealing pads are arranged at the cooperating positions of the valve body, the valve cover and the lower end of the support, a single-direction thrust ball bearing is arranged at the upper end of the support, a bearing pressing cover is arranged at the upper end of the single-direction thrust ball bearing, the valve rod and the support are fixed by a guide clamping plate, and an oil cup is arranged at the position, corresponding to the position of the single-direction thrust ball bearing, of the upper end of the support. The self-sealing pressure type stop valve with the double valve clacks effectively improves the sealing property and the working stability, reduces the abrasion of the valve rod and prolongs the service life.
Description
Technical field
The utility model relates to a kind of stop valve, particularly relates to a kind of pressure self-sealing Double-clack stop valve.
Background technique
The open-shut device of stop valve (stop valve, Globe Valve) is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat.According to the mobile form of flap, the variation of valve seat port is and flap stroke relation in direct ratio.Because valve rod unlatching or the shutoff stroke of such valve are relatively short, and there is cutting function very reliably, due to the variation of valve seat port and the stroke of flap relation in direct ratio, be very suitable for the adjusting to flow again.For current this kind of used valve, in use there is the not too good situation of certain sealing in it.
Model utility content
It is better that the technical problems to be solved in the utility model is to provide a kind of sealing, long service life, the pressure self-sealing Double-clack stop valve that stability is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is to provide a kind of pressure self-sealing Double-clack stop valve, comprise valve body, big valve flap, little flap, valve clack cover, valve rod, valve gap and support, one end of this valve rod is connected with handwheel through the Stem Mut on support, realized the driving of valve, its the other end is connected with little flap through valve gap, it is peripheral that this big valve flap is positioned at little flap, and this big valve flap is fixed by valve clack cover and valve rod, between this valve gap and valve rod, be equipped with successively from top to bottom Packing seat, filler, spacer ring and filler pressing sleeve, and hold-down grid is set on filler pressing sleeve, prevented the leakage of filler, this valve body, valve gap and the support three place of cooperatively interacting are equipped with wedge type sealing gasket, improved the sealing of valve, the upper end of this support and the Stem Mut place of cooperatively interacting are provided with single direction thrust ball bearing, and single direction thrust ball bearing upper end is equipped with bearing gland, guaranteed the stable of single direction thrust ball bearing.
Optimization as technique scheme: valve rod is fixed by guiding clamping plate and support, has increased the stability in using process.
Further optimization as technique scheme: upper end and single direction thrust ball bearing corresponding section at support are provided with lubricating cup, have reduced the abrasion between valve rod and single direction thrust ball bearing, thereby have increased the working life of valve.
The beneficial effects of the utility model are: effectively improved sealing and the working stability of valve, reduced the wearing and tearing of valve rod, increased the working life of valve.
