Abstract
The utility model discloses an air exchange valve with a limiting device. The air exchange valve with the limiting device comprises a shell, an air plate cross shaft used for allowing an air plate to be mounted is arranged in the middle of the shell, a driving pivot shaft is arranged in the shell, a separable driving gear is arranged on the driving pivot shaft, an air plate gear is arranged at the tail end of the air plate cross shaft, and the air plate gear is matched with the driving gear. According to the air exchange valve with the limiting device, through a locating shoulder on the air plate gear and an adjusting screw rod on the shell, a user can adjust the relative positions of a locating pin on the adjusting screw rod and the locating shoulder according to the needed stroke requirement for the air plate, the air plate can automatically stop when the air plate reaches the maximum stroke, the situation that the air plate continues to rotate to cause gear sliding is avoided, reliability of the air exchange valve is greatly improved, and the service life of the air exchange valve is greatly prolonged.
Description
Technical field
The utility model relates to a kind of industrial ventilation equipment, or rather, is a kind of ventilation valve with stopper.
Background technology
Ventilation valve is a kind of common industrial ventilation equipment, is conventionally arranged on main air duct, for controlling the air mass flow on main air duct.When aerofoil continue to rotate while approaching maximum position, due to the effect of inertia, aerofoil still can be rotated further, and causes being rotated further of driven wheel, easily causes gear slip teeth, large-scale aerofoil particularly, and the wearing and tearing of gear are even more serious, and maintenance cost is higher.
Summary of the invention
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of ventilation valve with stopper is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of ventilation valve with stopper, described ventilation valve with stopper comprises a housing, the middle part of described housing is provided with one for the aerofoil transverse axis of aerofoil is installed, in described housing, be provided with a driving pivot, described driving pivot is provided with a separable driven wheel, the horizontal the tip of the axis of described aerofoil is provided with an aerofoil gear, described aerofoil gear matches with described driven wheel, the connection disk body that described aerofoil gear comprises a circle, described connection disk body be circumferentially with a semiorbicular passive sector, the two ends of described passive sector are respectively equipped with a location shoulder, the top of described housing is provided with an adjusting through hole, in described adjusting through hole, be provided with an adjusting screw(rod), described adjusting screw(rod) comprises a screw rod main body, the bottom of described screw rod main body is provided with an alignment pin, described alignment pin matches with described one of them location shoulder.
As the utility model preferred embodiment, described alignment pin is provided with a back-moving spring.
Ventilation valve with stopper of the present utility model utilizes location shoulder on aerofoil gear and the adjusting screw(rod) on housing, the user as required stroke of aerofoil requires to regulate the alignment pin and the relative position of locating shoulder on adjusting screw(rod), when reaching range, aerofoil can automatically stop, prevent it to be rotated further and cause gear slip teeth, greatly having improved reliability and the service life of ventilation valve.This scavenging air valve door with stopper is simple, with low cost, practical.
