Abstract
The utility model relates to a leakage prevention direct tube regulation ball valve. A direct tube shape valve body is provided with two ball valves which consist of a ball body, a valve seat pressure sleeve, sealing ring, valve rod connected with the ball body, a gasket between the lower part of the valve rod and the valve body, a handle fixed at the upper end of the valve rod. The valve rod is provided with a convex stop block in the middle of the valve body, and the stop block and the valve rod are provided with a-shape ring, a sealing material and a pressure clamping nut. The back end part of the ball valve handle is provided with a concave groove hole, and the hole is provided with a spring and a steel ball. The steel ball is matched with concave grooves arranged on the valve body for locating. The utility model has advantages of compact structure, convenient operation, strong sealing, and can adjust the volume with practical valve.
Description
The utility model relates to a kind of anti-leak straight tube adjusting ball valve that is used for gas, liquid conducting pipes keying and regulates flow.
At present in manufacturing enterprises such as chemical industry, pharmacy, control valve all is housed on the process pipeline of its retort, great majority adopt stop valve, but common stop valve generally exists poor sealing performance, opens and closes inconvenient problem, the run, drip, leak phenomenon often appears, though what have has installed dual stop valve, still can not stop leakage phenomenon fully.In addition, general stop valve can not be located by switch, can't regulate control flow rate.
The anti-leak straight tube that the purpose of this utility model is to provide a kind of compact structure, preparation process is simple, easy to operate, sealing strong, the switch gear is accurate, can regulate flow is regulated ball valve.
The purpose of this utility model is achieved in that a kind of anti-leak straight tube adjusting ball valve, include a straight tube shape valve body, valve body is provided with two by the spheroid in the valve body, the valve seat gland, seal ring on the gland, pass the valve rod that valve body connects spheroid, pad between stem lower portion and the valve body, the ball valve that the handle that the valve rod upper end is overlapped by nut and spring washer fixing belt etc. constitutes, it is characterized in that valve rod passes the valve body intermediate portion and is provided with outstanding block, be provided with O type circle in block and between the valve rod, stuffing box packing and gland nut, guaranteed the sealing between valve body and the valve rod, stopped liquid toward external leakage.Be provided with recess hole in one of them ball valve handle rearward end, be provided with spring and steel ball in the hole, the groove that steel ball and valve body the are provided with location that is complementary, when moving handle position, steel ball in the rearward end is positioned in the corresponding grooves, spheroid forms different opening degrees with valve pocket, the flow that regulating and controlling is different.So ball valve can standard-sized sheet or complete shut-down reach break-make, another ball valve is regulated control flow rate.
The utility model compact structure, preparation process are simple, easy to install, and sealing is strong, the switch accurate positioning, regulates different flow.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is a valve body sectional view of the present utility model.
Shown in Fig. 1-2, a kind of anti-leak straight tube is regulated ball valve, include a straight tube shape valve body 9, valve body 9 is provided with two by the spheroid in the valve body 2, valve seat gland 3, seal ring 1 on the gland, pass the valve rod 4 that valve body connects spheroid, pad 5 between stem lower portion and the valve body, the valve rod upper end is by the handle 12 of nut 11 with spring washer 10 fixing belt sleeves, the ball valve that 15 grades constitute, it is characterized in that: valve rod 4 passes the valve body intermediate portion and is provided with outstanding block 19, be provided with O type circle 6 in the block and between the valve rod, stuffing box packing 7 and gland nut 8, be provided with recess hole 18 in one of them ball valve handle 12 rearward end, be provided with spring 13 and steel ball 14 in the hole, the groove 17 that steel ball and valve body the are provided with location that is complementary.
