Abstract
The utility model discloses an automatic inflation device for an inflation sealing valve and aims to solve the complicated problems of a synchronization mechanism for valve core operation of a sealing valve and inflation operation of an inflator. The automatic inflation device for the inflation sealing valve comprises a valve body, the inflator which is connected with the valve body, a rocking arm which is fixedly connected with a valve core in the valve body, a power device which is connected with the rocking arm, and an inflator pressing plate which is fixed on the rocking arm, wherein an air channel is formed in the valve body; one end of the air channel is provided with a sealing ring, and the other end of the air channel is connected with the inflator through a pipe; and the inflator and the power device are arranged outside the valve body. The automatic inflation device for the inflation sealing valve is simple in structure, low in cost and convenient to operate, and the operation synchronization of the valve core and the inflator can be realized without an electric control device.
Description
Technical field
The utility model relates to a kind of gas-flow closure valve self-filler.
Background technique
The spool action of gas-flow closure valve and the inflation action request of seal ring are corresponding synchronous, promptly in the spool action, also require inflator work; To the seal ring inflation, but the actuating mechanism of the actuating mechanism of spool and inflator is two cover mechanisms, in order to satisfy synchronous requirement; Corresponding control panel must be set; Complex structure, expense is high, has also increased rate of fault simultaneously.
The model utility content
To the problems referred to above, the utility model provides a kind of spool action that does not need control panel just can realize the gas-flow closure valve to inflate the device that carries out simultaneously with inflator.
For achieving the above object; The utility model gas-flow closure valve self-filler; Comprise valve body, the inflator that is connected with said valve body, the rocking arm that is fixedly connected with said valve body inner spool, with the hinged power plant of said rocking arm and be fixed on the inflator pressing plate on the said rocking arm; Be provided with air flue in the wherein said valve body, said air flue one end is provided with the seal ring the other end and connects said inflator through pipe.
Further, said power plant be oil hydraulic cylinder, cylinder or hydraulic push rod wherein any one.
Further, said inflator, said power plant are arranged on outside the said valve body.
Especially, said spool is connected through key with said rocking arm.
It is a cover that the startup inflator inflation in the spool action of the self-filler of the utility model gas-flow closure valve makes two cover mechanism simplifyings, no longer need control both synchronous electrical control mechanisms, simple and reliable for structure, cost, and rate of fault is low.
Description of drawings
Fig. 1 is the inflator inflation pre-structure schematic representation of the utility model gas-flow closure valve self-filler;
Fig. 2 is the inflator inflation back structural representation of the utility model gas-flow closure valve self-filler.
Embodiment
Below in conjunction with Figure of description the utility model is done further description.
Shown in Fig. 1-2; Gas-flow closure valve self-filler; Comprise valve body 1, the inflator 5 that is connected with said valve body 1, with hinged rocking arm 7, the power plant 9 that are connected with said rocking arm 7 of said valve body 1 inner spool 3 and be fixed on the inflator pressing plate 6 on the said rocking arm 7; Said inflator pressing plate 6 can be pressed onto on the gaseous core of said inflator 5 when said spool 3 rotates, and in addition, is provided with air flue in the said valve body 1; Said air flue one end is provided with seal ring 2 the other ends and connects the inflator 5 that charges and discharge gas through pipe 4.
Said power plant 9 can select else into oil hydraulic cylinder, cylinder, hydraulic push rod wherein any one, can drive valve core rotation and get final product, be preferably hydro cylinder at present relatively more commonly used.
Preferred embodiment: when the said rocking arm 7 of oil hydraulic cylinder 9 promotions is swung; Said rocking arm 7 drives said spool 3 and rotates simultaneously with inflator pressing plate 6, thereby when said spool 3 rotated, said inflator pressing plate 6 was pressed to the inflator gaseous core; Said inflator 6 gives seal ring described in the said valve body 12 inflations; Said seal ring 2 is heaved to the working position, and the gas-flow closure valve reaches working state, so reaches valve core rotation and the inflator inflation purpose of action simultaneously.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
