The lifting-type three-way plug valve comprises a three-way valve body, a packing gland is arranged on the valve body, a valve spool is movably arranged in the valve body, a fluid channel is arranged in the valve spool, the lower portion of the valve spool is provided with an inverted cone, the top of the valve spool penetrates out of the packing gland which is provided with a mounting frame, a threaded bushing capable of rotating freely is penetratingly arranged in the mounting frame, the valve spool is nested in the threaded bushing through a thread arranged on the valve spool, a lifting handle capable of rotating is arranged on the threaded bushing, and a reversing handle is arranged at the top of the valve spool.
Description
Technical field
The utility model relates to a kind of lifting type threeway plug valve.
Background technique
Common threeway plug valve, comprises three way valve, and valve body is provided with Gland, is movably equipped with spool in valve body, and spool is provided with liquid outlet channel, and spool bottom is inverted cone-shaped, and spool top passes from Gland, and spool top is provided with reversing handle.Because spool bottom is inverted cone-shaped, and be sealed and matched between valve body, so extremely require great effort when spool is opened or closes, the operating time is long.
Model utility content
Technical problem to be solved in the utility model is: a kind of unlatching lifting type threeway plug valve is easily provided.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of lifting type threeway plug valve, comprise three way valve, valve body is provided with Gland, in valve body, be movably equipped with spool, spool is provided with liquid outlet channel, spool bottom is inverted cone-shaped, spool top passes from Gland, Gland is provided with scaffold, is equipped with thread bush free to rotate in scaffold, and spool is embedded in thread bush by the screw thread arranging on it, thread bush is provided with rotation lifting handle, and spool top is provided with reversing handle.
As a kind of preferred scheme, described thread bush comprises that inside is provided with the upper press cover of tapped through hole, and upper press cover bottom periphery has been threaded connection setscrew nut.
As a kind of preferred scheme, described three way valve inherence is provided with groove over against place, spool bottom.
As a kind of preferred scheme, in described spool, be provided with L-shaped liquid outlet channel.
As the preferred scheme of another kind, the liquid outlet channel in described spool is in T shape, comprises a liquid entering hole and two liquid outlets.
The beneficial effects of the utility model are: owing to being equipped with thread bush free to rotate in scaffold, spool is embedded in thread bush by the screw thread arranging on it, thread bush is provided with rotation lifting handle, spool top is provided with reversing handle, when opening spool, first rotary lifting handle, then rotate reversing handle, the power of using when spool is opened reduces greatly; Solved the situation that reversing handle can not be opened immediately spool, occur jam of in the past directly rotating.
Because three way valve inherence is provided with groove over against place, spool bottom, the fluid having in groove can make turning to of spool open and become easy.
Owing to being provided with L-shaped liquid outlet channel in spool, can liquid entering hole need to be communicated with corresponding liquid outlet according to using by rotary spool like this.
Because the liquid outlet channel in spool is in T shape, comprise a liquid entering hole and two liquid outlets, can liquid entering hole need to be communicated with two liquid outlets according to using by rotary spool so simultaneously, or only be communicated with corresponding liquid outlet.

In Fig. 1 to Fig. 6: 1. three way valve, 2. spool, 3. liquid outlet channel, 4. groove, 5. Gland, 6. scaffold, 7. thread bush, 71. upper press covers, 72. setscrew nuts, 8. lifting handle, 9. reversing handle.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As Figure 1-3, a kind of lifting type threeway plug valve, comprises three way valve 1 to embodiment 1, valve body is provided with Gland 5, is movably equipped with spool 2 in valve body, and spool 2 bottoms are inverted cone-shaped, wherein be provided with liquid outlet channel in T shape 3, comprise a liquid entering hole and two liquid outlets.Three way valve 1 inherence is provided with groove 4 over against spool 2 places, bottom.Spool 2 tops pass from Gland 5, Gland 5 is provided with scaffold 6, in scaffold 6, be equipped with thread bush free to rotate 7, described thread bush 7 comprises that inside is provided with the upper press cover 71 of tapped through hole, and upper press cover 71 bottom peripheries have been threaded connection setscrew nut 72.Spool 2 is embedded in thread bush 7 by the screw thread arranging on it, and thread bush 7 is provided with and rotates lifting handle 8, and spool 2 tops are provided with reversing handle 9.
As Figure 4-Figure 6, itself and embodiment's 1 difference is embodiment 2, in described spool 2, is provided with L-shaped liquid outlet channel 3.
When opening spool 2, first rotary lifting handle 8, thread bush 7 rotates thereupon, because spool 2 is embedded in thread bush 7 by the screw thread arranging on it, the rotation of thread bush 7 forces the spool 2 micro-stroke that moves upward, because bottom is inverted cone-shaped, after moving upward and between valve body, produce space, rotate so reversing handle 9, the power of using when spool 2 is opened reduces greatly, is easy to just rotatably open spool 2 again.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
