Abstract
The utility model discloses a piston end plug. The piston end plug comprises an end plug body, wherein step-type grooves are formed in the bottom end of the contact surface of the end plug body and an externally-connected piston rod, and comprises a first groove and a second groove, a seal ring is arranged in the first groove in a matching manner, and a baffle is fixed on the second groove in a matching manner. Through arranging step-type grooves at the bottom end of the contact surface of the end plug body and an externally-connected piston rod, the processing of the grooves is convenient, and the probability of eccentric grooves is reduced, so that the leakage probability is low; as the seal ring is a dual-lip seal ring, the sealing degree is higher.
Description
Technical field
The utility model relates to a kind of end plug, is specifically related to a kind of piston end plug.
Background technique
In water softening device, an end plug is set between piston and valve body, on end plug, opens a through hole mated with piston rod, in through hole, offer an annular groove, in order to fixed seal ring, this groove generally can only machine by machinery, but the groove that machinery is offered, often because of reasons such as mechanical precisions, it is eccentric groove that the groove completed has certain probability, the seal ring of installing and groove can not be mated fully, have space, produce leakage problem.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of piston end plug, has solved because of eccentric groove, and the seal ring of installing and groove can not be mated fully, has space, produces leakage problem.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of piston end plug, comprise end plug body, the bottom of described end plug body and external piston rod surface of contact is provided with the ladder-type groove, and described ladder-type groove comprises the first groove and the second groove, in described the first groove, be provided with the seal ring of coupling, in described the second groove, be fixed with the baffle plate of coupling.
Described seal ring is double-lip sealing ring, and seal degree is higher, enhanced leaktightness.
Described baffle plate is welded in the second groove, firm and reliable connection.
Beneficial effect: the utility model arranges the ladder-type groove by the bottom at end plug body and external piston rod surface of contact, makes Pocket Machining convenient, and the probability of eccentric groove is low, is difficult for producing leakage problem; Seal ring is double-lip sealing ring simultaneously, and seal degree is higher.
The accompanying drawing explanation
Fig. 1 is the structural drawing that the utility model is connected with piston rod.
Fig. 2 is the structural drawing of end plug body.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As illustrated in fig. 1 and 2: a kind of piston end plug, comprise end plug body 3, described end plug body 3 is provided with the ladder-type groove with the bottom of external piston rod surface of contact, described ladder-type groove comprises the first groove 41 and the second groove 42, in described the first groove 41, be provided with the seal ring 2 of coupling, in described the second groove 42, be fixed with the baffle plate 1 of coupling.
Described seal ring 2 is double-lip sealing ring, and seal degree is higher, enhanced leaktightness.
Described baffle plate 1 is welded in the second groove 42, firm and reliable connection.
In processing during end plug, in the bottom of described end plug body 3 and external piston rod surface of contact manually or machining ladder-type groove, then double-lip sealing ring is arranged in the first groove 41, then baffle plate 1 is welded in the second groove 42 and gets final product.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
