Abstract

The utility model discloses a sleeving-type ball valve which comprises a valve body, a valve seat, a valve rod, a ball body, a filler, a filler gland and a handle, wherein the filler is arranged between the valve rod and the valve seat; the lower end of the valve rod is fixedly connected with the ball body; the upper end of the valve rod is fixedly connected with the handle through a screw; the valve body is provided with a water inlet and a water outlet; the water inlet and the water outlet of the valve body are both fixedly connected with a double card through nuts; a seal ring which is movably connected with the valve seat is arranged at the sealed part of the ball body and the valve seat. The sleeving-type ball valve provided by the utility model has the beneficial effects that the sleeving-type ball valve is simple in structure, small in fluid resistance, small in volume, and light in weight, is tight and reliable, has a good seal property, is convenient to operate, can be started and closed rapidly, only needs to be rotated by 90 degrees from full starting to full closing, is convenient to control in long distance, and is convenient to maintain; an air source ball valve is simple in structure, seal rings are generally movable, and are relatively convenient to detach and replace; and in full starting or full closing, seal surfaces of the ball body and the valve seat are separated from media, and when the media passes, the seal surface of the valve can not be eroded.

Description

A kind of FERRULETYPE ball valve
Technical field
The utility model belongs to valve field, particularly a kind of FERRULETYPE ball valve.
Background technique
Gas source valve is mainly used to make cut-out, distributes and change the flow direction of medium in pipeline, what traditional gas source valve adopted is common stop valve, and its shortcoming is that fluid resistance is large, complex structure, operation are inconvenient, fragile, difficult keep in repair etc.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of fluid resistance minor structure simple FERRULETYPE ball valve.
To achieve these goals, technical solution adopted in the utility model is:
A kind of FERRULETYPE ball valve comprises valve body, valve seat, valve rod, spheroid, filler, Gland and handle, is provided with filler between described valve rod and valve seat, the affixed spheroid in valve rod lower end, and the valve rod upper end is by the affixed handle of screw, and valve body is provided with water intake and water outlet; Water intake and the water outlet of valve body all are connected with double card by nut.
As preferably, described spheroid and valve base sealing place are provided with seal ring, and seal ring and valve seat are flexibly connected.
The beneficial effects of the utility model: the utility model is simple in structure, fluid resistance is little, volume is little, lightweight; Closely reliable, the seal face materials of source of the gas ball valve is widely used plastics, good airproof performance at present, also is widely used in vacuum system; Easy to operate, open and close rapidly, need only half-twist from the standard-sized sheet to the complete shut-down, be convenient to remote control; Easy to maintenance, the source of the gas ball-valve structure is simple, and seal ring is all generally movable, and dismounting and change is all more convenient; When standard-sized sheet or full cut-off, the sealing surface of spheroid and valve seat and medium isolation when medium passes through, can not cause the erosion of valve sealing face.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of FERRULETYPE ball valve as shown in Figure 1, comprise valve body 1, valve seat 9, valve rod 6, spheroid 7, filler 2, Gland 3 and handle 4, be provided with filler 2 between described valve rod 6 and valve seat 9, the valve rod 6 affixed spheroids 7 in lower end, valve rod 6 upper ends are by the affixed handle 4 of screw 5, and valve body 1 is provided with water intake and water outlet; The water intake of valve body 1 and water outlet all are connected with double card 10 by nut 8; Described spheroid 7 is provided with seal ring with valve seat 9 sealings place, and seal ring and valve seat flexible connection.
The utility model is simple in structure, fluid resistance is little, volume is little, lightweight; Closely reliable, the seal face materials of source of the gas ball valve is widely used plastics, good airproof performance at present, also is widely used in vacuum system; Easy to operate, open and close rapidly, need only half-twist from the standard-sized sheet to the complete shut-down, be convenient to remote control; Easy to maintenance, the source of the gas ball-valve structure is simple, and seal ring is all generally movable, and dismounting and change is all more convenient; When standard-sized sheet or full cut-off, the sealing surface of spheroid and valve seat and medium isolation when medium passes through, can not cause the erosion of valve sealing face.
Be more than the utility model preferred forms, in related domain, those skilled in the art's simple change and replacement are all within protection domain of the present utility model.
