Abstract
The utility model provides an inflating-deflating check valve. According to the technical scheme, the inflating-deflating check valve comprises a valve body, a mandrel is arranged inside the valve body, one end of the mandrel, close to an air valve of the valve body, is a cone-shaped body with a groove, a spring and a vent shaft are sleeved at the other end of the mandrel, the spring is clamped between the vent shaft and the mandrel, a check ring is fixed at the tail end inside the valve body, the vent shaft tightly abuts against the check ring, and an inner sealing ring is arranged on the groove of the mandrel. The inflating-deflating check valve is capable of preventing the mandrel from being touched due to incorrect operation, and guarantees normal operation of a device.
Description
Technical field
The utility model relates to a kind of venting gas appliance, especially a kind of exhaust check valve that fills.
Background technique
In the prior art, technique known is that most single-pass outlet valves is not taked protective gear to mandrel, and the touching of personnel's misoperation meeting sometimes mandrel causes mandrel to damage, and this is the existing in prior technology deficiency.
The model utility content
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of exhaust check valve technological scheme of filling is provided, and this scheme can prevent that misoperation from running into mandrel, the assurance device proper functioning.
This programme is realized by following technical measures: a kind of exhaust check valve that fills, include valve body, and be provided with mandrel in the valve body; Mandrel is the taper that has groove near an end of valve body valve; Mandrel the other end outside is with spring and ventilating shaft; Spring clip is between ventilating shaft and mandrel; Tail end in the valve body is fixed with back-up ring; Ventilating shaft abuts against on the back-up ring; The groove of mandrel is provided with inner seal ring.
Preferred as this programme: the valve body outside is with exterior seal ring.
Preferred as this programme: the valve body front end is provided with protective cap.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to be provided with mandrel in the valve body in this scheme; Mandrel is the taper that has groove near an end of valve body valve; Mandrel the other end outside is with spring and ventilating shaft; Spring clip is between ventilating shaft and mandrel; Tail end in the valve body is fixed with back-up ring; Ventilating shaft abuts against on the back-up ring; The groove of mandrel is provided with inner seal ring, can effectively reach the function that the valve body single-pass fills exhaust; The valve body front end is provided with protective cap, can protect mandrel, prevents that misoperation from damaging mandrel, and the equipment of destruction sealing.
This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is protecting jacket, and 2 is valve body, and 3 is exterior seal ring, and 4 is back-up ring, and 5 is ventilating shaft, and 6 is spring, and 7 is mandrel, and 8 is inner seal ring.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing as can be seen, be provided with mandrel in the valve body of this programme; Mandrel is the taper that has groove near an end of valve body valve; Mandrel the other end outside is with spring and ventilating shaft; Spring clip is between ventilating shaft and mandrel; Tail end in the valve body is fixed with back-up ring; Ventilating shaft abuts against on the back-up ring; The groove of mandrel is provided with inner seal ring; The valve body outside is with exterior seal ring; The valve body front end is provided with protective cap.
