Abstract

The invention provides a heavy-hammer type flap valve, wherein energy is saved in the operating process, the fault rate of equipment is low, and the maintenance cost is low, thereby the economic benefit of the heavy-hammer type flap valve is ensured. The heavy-hammer type flap valve comprises a valve body and a valve plate, wherein the inner part of the valve body comprises an inlet, a passage and an outlet, and the inlet of the valve body is covered by the valve plate in a closed state. The heavy-hammer type flap valve is characterized in that: the valve plate is connected with one end of a rotating shaft through a connecting rod, the rotating shaft is supported on the outer wall of the valve body through a bearing, the other end of the rotating shaft is exposed out of the valve body, the other end of the rotating shaft is sleeved with a threaded rod, and a heavy hammer is connected with the threaded rod in a threaded mode through internal threads.

Description

The heavy hammer type Flap valve

Technical field

The present invention relates to the technical field of the valve mechanism of material import and export in the industrial trade, be specially the heavy hammer type Flap valve.

Background technique

Existing Flap valve comprises electronic, pneumatic and hydraulic pressure Flap valve etc., all through forcing power to carry out work.The energy that this type of Flap valve need utilize mineral fuel to be transformed is unfavorable for energy saving, has also reduced economic benefit; Its equipment failure rates such as electronic, pneumatic and hydraulic pressure that are equipped with can increase maintenance cost than higher, and can influence continuous commercial production, for enterprise makes troubles, and reduce economic benefit.

Summary of the invention

To the problems referred to above, the invention provides the heavy hammer type Flap valve, its running is energy-conservation, and rate of breakdown is low, and maintenance cost is low, has guaranteed its economic benefit.

The heavy hammer type Flap valve, its technological scheme is such: it comprises valve body, valve plate, the inside of said valve body comprises import, passage, outlet; The import of the said valve body of valve plate capping under the closed state; It is characterized in that: said valve plate connects said rotating shaft one end through connecting rod, and said rotating shaft is supported on the outer wall of said valve body through bearing, and the other end of said rotating shaft exposes to said valve body; The other end of said rotating shaft is set with threaded stem, and weight is through the internal thread said threaded stem that is threaded.

It is further characterized in that: said valve plate is positioned at the inside of said valve body, and said weight is positioned at the outside of said valve body, and said rotating shaft runs through the individual layer outer wall of said valve body;

Said channel vertical is to layout, and said import, outlet lay respectively at the vertical two ends of said valve body;

One side of said valve body has access door;

Said rotating shaft horizontal arrangement, the respective side of the position of the installation rotating shaft of said valve body is equipped with cover plate, and said cover plate is parallel with the position of the center line of said rotating shaft.

After adopting structure of the present invention, under the gravity of weight, arm of force acting in conjunction, valve plate is in closed state, and material falls to import afterwards; When accumulation of material on the valve plate arrives constant weight, turn under the valve plate, because valve plate is closed in the weight effect once more, realize the purpose of automatic discharging after the discharging; Its running is energy-conservation, and in addition, because total is simple, its rate of breakdown is low; Even break down, its maintenance cost is low, has further guaranteed economic benefit.Because the other end of rotating shaft is set with threaded stem, weight is through the internal thread threaded stem that is threaded, and weight can arbitrarily be adjusted at the position on the threaded stem, reaches the stepless adjustment of the arm of force, makes its material that can adapt to multiple proportion, and is applied widely.
