Description
Technical field
The utility model relates to valve technology field, is specially a kind of stop valve.
Background technique
Valve rod in tradition stop valve is all solid, involve great expense, and the outer pipe in traditional stop valve is in the process be connected with flexible pipe, and the joint of outer pipe and flexible pipe is because of hydraulic pressure often easy distending.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of, stop valve that cost low good with flexible pipe switching performance.
For achieving the above object, the utility model provides following technological scheme: a kind of stop valve, comprise valve body, valve rod in cavity in valve body is threaded connection, valve rod is connected with for opening and closing and the interior water squeezing plate in cavity, back-up ring is provided with in described valve body, described water squeezing plate is connected with the setting-out skin with back-up ring adaptation, described valve body is connected with the valve gap for limiting stem position, sealing gasket is provided with between valve gap and valve body, an O shape circle is provided with between valve gap and valve rod, described valve body is provided with outer pipe, outer pipe has been threaded connection sleeve cap, the 2nd O type circle is provided with successively between outer pipe and sleeve cap, packing ring and cutting ferrule.
Further, described sleeve cap is provided with attachment hole, and described attachment hole comprises macropore and aperture, and macropore is connected by annular slope with aperture.
Further, described cutting ferrule comprises the cover ring body with macropore adaptation, and cover ring body is provided with breach, is provided with the slideproof tooth of ring-type in cover ring body, cover ring body is also provided with the chamfering of annular slope adaptation.
Further, described valve rod is connected with cubic handwheel by latch.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: the 1. outside thread of valve rod of the present utility model is connected with the internal thread of valve body, and the internal thread on valve rod is connected with the outside thread of water squeezing plate, whole connection procedure assembling is simple, and water squeezing plate and valve rod are all interior in hollow, at the bottom of materials'use amount in the valve of Board Lot, and then make cost lower.2. when sleeve cap is tightened, impel cutting ferrule respectively to packing ring and the extruding of the 2nd O shape circle, reach the state of sealing, and when cutting ferrule is expressed to a certain degree, cutting ferrule tightens, cutting ferrule enters in annular slope, and breach closes, and the internal diameter of cutting ferrule reduces, for banding flexible pipe, and be also provided with slideproof tooth in cutting ferrule, increase the frictional force between cutting ferrule and flexible pipe, effectively prevent the phenomenon of joint distending because of hydraulic pressure of the outer pipe of valve and flexible pipe from occurring.

Fig. 2 is the G portion enlarged diagram of Fig. 1.
Fig. 3 is the structural representation of cutting ferrule.
Fig. 4 is the cross-sectional schematic of sleeve cap.
Embodiment
With reference to Fig. 1-Fig. 4, the utility model is described further.
A kind of stop valve, comprise valve body 1, valve rod 2 in cavity in valve body 1 is threaded connection, valve rod 2 is connected with for opening and closing and the interior water squeezing plate 3 in cavity, back-up ring 11 is provided with in described valve body 1, described water squeezing plate 3 is connected with the setting-out skin 31 with back-up ring 11 adaptation, described valve body 1 is connected with the valve gap 4 for limiting valve rod 2 position, sealing gasket 51 is provided with between valve gap 4 and valve body 1, be provided with an O shape between valve gap 4 and valve rod 2 and enclose 52, described valve body 1 is provided with outer pipe 12, outer pipe 12 has been threaded connection sleeve cap 6, the 2nd O type circle 53 is provided with successively between outer pipe 12 and sleeve cap 6, packing ring 54 and cutting ferrule 7.
The outside thread of valve rod 2 is connected with the internal thread of valve body 1, and the internal thread on valve rod 2 is connected with the outside thread of water squeezing plate 3, whole connection procedure assembling is simple, and water squeezing plate 3 and valve rod 2 are all interior in hollow, at the bottom of materials'use amount in the valve of Board Lot, and then make cost lower.
Further, described sleeve cap 6 is provided with attachment hole 61, and described attachment hole 61 comprises macropore 611 and aperture 612, and macropore 611 is connected by annular slope 613 with aperture 612.
Further, described cutting ferrule 7 comprises the cover ring body 71 with macropore 611 adaptation, and cover ring body 71 is provided with breach 72, is provided with the slideproof tooth 73 of ring-type in cover ring body 71, cover ring body 71 is also provided with the chamfering 74 of annular slope 613 adaptation.
When sleeve cap 6 is tightened, impel cutting ferrule 7 respectively to packing ring 54 and the extruding of the 2nd O shape circle, reach the state of sealing, and when cutting ferrule 7 is expressed to a certain degree, cutting ferrule 7 tightens, cutting ferrule 7 enters in annular slope 613, and breach 72 closes, and the internal diameter of cutting ferrule 7 reduces, for banding flexible pipe, and be also provided with slideproof tooth 73 in cutting ferrule 7, increase the frictional force between cutting ferrule 7 and flexible pipe, effectively prevent the outer pipe 12 of valve from occurring with the phenomenon of joint distending because of hydraulic pressure of flexible pipe.
Further, described valve rod 2 is connected with cubic handwheel 8 by latch.
Design cubic handwheel 8, add frictional force, convenient unlatching or throttle down.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
