Abstract

The utility model discloses an automatic drain valve for a muffler, which comprises an elastic connector which is fixed on the muffler and communicates with the muffler, a drain outlet and a bottom plate arranged at the bottom of the elastic connector. The drain outlet is formed on the side wall at the lower end of the elastic connector; and the elastic connector is made of rubber. The drain valve can be opened due to its own gravity to be in a drain state when an exhaust system is out of work; and can be sucked on the muffler due to the suction pressure generated by the exhaust gas when the exhaust system works, without noise. The drain valve can drain the accumulated water in time, so as to prolong the service life of an engine and the muffler.

Description

The silencing apparatus automatic drain valve
Technical field
The utility model relates to a kind of automatic drain valve, particularly a kind of silencing apparatus automatic drain valve.
Background technique
At present, the silencing apparatus that existing truck exhaust is used on the market, particularly the silencing apparatus of vertically installing often has into water phenomenon, but corresponding drainage means is not installed on the silencing apparatus, owing to have ponding in the silencing apparatus, thereby greatly reduce the working life of silencing apparatus and motor.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of energy self-draining silencing apparatus automatic drain valve.
In order to solve the problems of the technologies described above, silencing apparatus automatic drain valve of the present utility model, comprise be fixed on silencing apparatus on and the nonrigid connector, the drain opening that are connected with silencing apparatus and be arranged on the base plate of nonrigid connector bottom, described drain opening is arranged on the sidewall of nonrigid connector lower end.
Silencing apparatus automatic drain valve of the present utility model, described nonrigid connector is made by rubber.
The beneficial effect that the utility model is obtained is: when did not work when vent systems (1), drain valve was opened because of self gravitation, is in hull-borne; When the vent systems exhaust, drain valve can be pull-in on the silencing apparatus because of the negative pressure that exhaust produces, and does not produce noise; (2) can in time ponding be discharged, can prolong the working life of motor and silencing apparatus.
Description of drawings
Schematic representation when Fig. 1 is the utility model draining on silencing apparatus.
Schematic representation when Fig. 2 is not draining of the utility model on silencing apparatus.
Fig. 3 is the structural representation after the utility model amplifies.
Among the figure: 1, silencing apparatus, 21, nonrigid connector, 22, drain opening, 23, base plate.
Embodiment
As shown in Figure 3, silencing apparatus automatic drain valve of the present utility model, comprise be fixed on silencing apparatus 1 on and the nonrigid connector 21, the drain opening 22 that are connected with silencing apparatus 1 and be arranged on the base plate 23 of nonrigid connector bottom, described drain opening is arranged on the sidewall of nonrigid connector 21 lower ends; Described nonrigid connector 21 is made by rubber.
As shown in Figure 1, when vent systems was not worked, drain valve was opened because of self gravitation, is in hull-borne.
As shown in Figure 2, when the vent systems exhaust, drain valve can be pull-in on the silencing apparatus because of the negative pressure that exhaust produces, and does not produce noise.
