Abstract
The utility model provides a pilot-operated pneumatic stop valve comprising a valve body, a cylinder arranged in the valve body, a rod cavity connected with the lower end of the cylinder, and a valve base disposed at the bottom of the valve body. The stop valve is characterized in that a guide valve core is arranged at the upper end of the valve base and between the valve base and a main valve core, the area of the main valve core is larger than that of the guide valve core, two sides of the main valve core are respectively provided with a flow guide body, and the rod cavity and the main valve core are connected through a piston. The guide valve core is arranged between the main valve core and the valve base and the area of the main valve core is larger than that of the guide valve core, so starting force to open the guide valve is small. Meanwhile, due to the flow guide bodies, force applied by a medium on the main valve core is reduced. The guide valve core drives the main valve core to move so that air pressure opening of the valve cores is achieved and the stop valve is simple to operate.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of stop valve.
Background technique
Stop valve refers to that closure member prolongs the valve that the valve seat center line moves.The structural type of valve body has straight-through type, direct current type and right-angle type.The right-angle type valve body adopts forging more, is applicable to the stop valve of less latus rectum, elevated pressures, and the spool in this stop valve has been disposed radially the water port, and the rotation by spool in valve body changes the water flowing area of water port, thereby changes the current size.Reduce the water flowing area, can cause hydraulic pressure to become large, water velocity accelerates, and noise increases.When flowing water passed through the water port, current attenuated and can not be full of whole follow-up water pipe, bring error to flow monitoring.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of stop valve, comprise valve body, be arranged on the valve body two ends water intake and water outlet, be arranged on spool and valve rod in valve body, be connected to the handle of valve body upper end, it is characterized in that: constant-current stabilizer is set in valve body, and it is inner that this constant-current stabilizer is arranged on the valve body water outlet.
The beneficial effects of the utility model are: valve body water outlet inside arranges constant-current stabilizer, reduced the water velocity of valve body water outlet, the buffering water flow impact pressure, and reduced the noise of current in valve body and to the impact of follow-up component, improved the precision of flow monitoring.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further explained explanation, as figure, 1-valve body, 2-spool, 3-valve rod, 4-constant-current stabilizer, 5-water intake, 6-water outlet, 7-handle.
Embodiment
As shown in Figure 1, at valve body 1 two ends, water intake 5 and water outlet 6 are set respectively, interior spool 2 and the valve rod 3 of arranging of valve body 1, valve rod 3 lower ends are connected with spool 2, and the upper end is connected with handle 7, in water outlet 6 inside of valve body 1, constant-current stabilizer 4 is set.
In concrete using process, rotatable handle 7 is opened spool 2 by the effect of valve rod 3, and current are flowed in spool 2 by water intake 5, flows out after constant-current stabilizer 4 processing of water outlet 6 inside, and rotatable handle 1 is closed spool 2, and current stop.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
