Abstract
The utility model relates to a check valve, and particularly provides a cushion swing check valve applicable to the conditions of high temperature and severe working condition. The cushion swing check valve structurally comprises a valve body provided with an inlet passage and an outlet passage; a valve cover is arranged above the valve body; a valve seat is arranged inside the valve body; a valve clack arranged on the valve seat is connected with one end of a rocking bar through a nut and a gasket; the other end of the rocking bar is fixed onto a rocking bar shaft inside the valve body; and a linkage device arranged outside the valve body is further fixed onto the rocking bar shaft. Compared with the prior art, the cushion swing check valve has the advantages of reasonable design, simple structure, low noise and capabilities of controlling flow and performing remote operation under high-temperature and high-pressure conditions.
Description
Technical field
The utility model relates to a kind of safety check, and a kind of buffering Swing check valve that is applicable under high temperature and the working condition condition of severe specifically is provided.
Background technique
Existing safety check all adopts 5 ° of inclined-plane flaps, it is contact with valve body sealing surface by self weight, and this structure noise of valve generation in actual use is big, and lacks the working life of valve, limited its using scope greatly, again the flow of uncontrollable valve.
Summary of the invention
The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, noise is little, can use and carry out flow control and remote-operated buffering Swing check valve under high temperature and high pressure environment.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of buffering Swing check valve, comprise and be provided with the valve body of importing and exporting passage, described valve body top is provided with valve gap, be provided with valve seat in the described valve body, described valve seat is provided with flap, described flap is by an end of nut and pad connection rocking bar, and the other end of described rocking bar is fixed on the interior rocker shaft of valve body, also is fixed with the connecting rod means that is arranged at described valve body outside on the described rocker shaft.
The other end of rocking bar is maintained fixed by flat key and rocker shaft.
Connecting rod means comprises connecting rod, described connecting rod one end is fixed on the rocker shaft, the other end is provided with weight, described connecting rod middle part connects an end of cylinder apparatus, the set oil cylinder stationary axle of the other end of described cylinder apparatus is fixed on the described valve outer wall, and the upper and lower return tube place of described cylinder apparatus is provided with pneumatic ball valve.
Valve gap is provided with suspension ring.
Rocker shaft is outside equipped with divided ring, and the graphite packing of packing between rocker shaft and axocoel, and its axocoel outermost end is by the fixing Gland of high-pressure bolt.
Buffering Swing check valve of the present utility model, it is provided with the valve body of importing and exporting passage, and connecting rod means is set outside valve body, make the interior flap of valve open Shi Buhui and cause the big problem of noise, connecting rod and heavily beat the Slow Close effect of having played when it designs, improve the working life of valve so greatly, sealed tight effect.Flap is by connecting rod Unscrew and the design of closing, designed pneumatic ball valve on the oil cylinder of valve body outside connecting rod device, flow when can the telecontrol valve opening, pneumatic ball valve can be when valve open fixing flap, flap is under any state, and then the flow when can control valve opening and and make other telecontrol.Compared with prior art, its have more reasonable in design, simple in structure, noise is little, can use and carry out flow control and remote-operated characteristics under high temperature and high pressure environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural front view that cushions Swing check valve;
