Chamber is accepted in bar filler, gland, leakage, and the upper end of the lift shaft is fixedly connected with the handwheel, and the lift shaft is provided with
Screw thread, mounting flange is fixedly connected with the valve rod mounting seat, and the valve rod mounting seat is fixedly connected with the valve body, the lift shaft
Spun with the mounting flange screw thread, the lower end of the lift shaft is provided with the first fixture block, and the upper end of the valve rod is provided with the second card
Block, the axle guide pad is provided with neck, and first fixture block, the second fixture block are placed in the neck, the handle and the valve
Bar is fixedly connected, and the valve rod mounting seat is provided with the first heap weld-ring, and the valve plug is provided with the second heap weld-ring, the first heap weld-ring
Matched with the second heap weld-ring, the leakage accepts chamber and is located at valve body, the leakage is accepted chamber and is located at below the valve plug.Institute
State and sealing ring is provided between valve rod mounting seat and the valve body.
The beneficial effects of the utility model：When opening plug valve, handwheel is first rotated into faint angle, the spiral shell in lift shaft 3
In the presence of line, lift shaft 3 is moved upwards, and this axle guide pad 4 can cause valve rod 1, lift shaft 3 are independent of each other to surround central shaft
Rotation, the overall structure that can be also made up of lift shaft 3, valve rod 1 realizes pull-up, downward motion.So that valve plug 2 and valve body 18 are tight
The tactile sealing surface of contiguity departs from, then pulls 90 degree of light Open valves of handle.During cut-out tap valve, reversely pull on the basis of the above
90 degree of fixed handle, and rotate backward handwheel and realize that valve plug 2 and combining closely for valve body 18 reach sealed effect.So that valve is grasped
Make laborsaving convenience；Leakage accept chamber 10 be used for bottom accept for leakage, the leakage when really there is valve leak
In leakage and valve body, without leaking to outdoor, and the first heap weld-ring 16 is matched with the second heap weld-ring 17, in valve rod 1 and valve rod
Increase back seal at mounting seat 7.New technical scheme is provided in the technical problem that plug valve is leaked so that plug valve
Anti- leakage ability greatly enhance.
Brief description of the drawings
Fig. 1 is the structural representation of this lifting type plug valve.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing.
In Fig. 1：Valve rod 1, valve plug 2, lift shaft 3, axle guide pad 4, handwheel 5, handle 6, valve rod mounting seat 7, valve stem packing
8th, chamber 10, mounting flange 11, fix bar 12, the first fixture block 13, the second fixture block 14, neck 15, the are accepted in gland 9, leakage
A pile weld-ring 16, the second heap weld-ring 17, valve body 18, sealing ring 19.
The structure of lifting type plug valve：The valve plug 2 that lifting type plug valve includes valve rod 1, is fixedly connected with the lower end of valve rod 1,
The lifting type plug valve also includes lift shaft 3, axle guide pad 4, handwheel 5, handle 6, valve rod mounting seat 7, valve stem packing 8, filled out
Expect that gland 9, leakage accept chamber 10, the upper end of lift shaft 3 is fixedly connected with the nut of handwheel 5, and lift shaft 3 is provided with screw thread, Method for Installation
Orchid 11 is fixedly connected with valve rod mounting seat 7, and valve rod mounting seat 7 and valve body 18, mounting flange 11 are pacified by fix bar 12 and valve rod
Dress seat 7 is fixedly connected, and lift shaft 3 spins with the screw thread of mounting flange 11, and the lower end of lift shaft 3 is provided with the first fixture block 13, valve rod 1
Upper end is provided with the second fixture block 14, and axle guide pad 4 is provided with neck 15, and the first fixture block 13, the second fixture block 14 are placed in neck 15, uses
The axle guide pad 4 of two halves by the first fixture block 13, the clamping connection of the second fixture block 14 in neck 15, first fixture block 13, the second fixture block
14 can the freely activity in neck 15.Handle 6 is connected with the square key of valve rod 1, and valve rod mounting seat 7 is provided with the first heap weld-ring 16, valve plug 2
Provided with the second heap weld-ring 17, the first heap weld-ring 16 is matched with the second heap weld-ring 17, the first heap weld-ring 16 and the shape of the second heap weld-ring 17
