Embodiment Construction

[0011] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] see figure 1 , the present invention has a valve body 1, and the valve body 1 is equipped with two flaps 2 arranged opposite to each other. The ends of the two flaps 2 are butted to form a right angle structure. The pin shaft A9 is fixedly installed, and the two ends of the pin shaft A9 protrude outwards to be rotatably connected with the valve body 1, and the ends of the two pin shafts A9 are fixedly equipped with a counterweight rod 12, and the counterweight bar 12 is equipped with a counterweight 14; In particular: the valve body 1 is provided with an arc-shaped baffle 10 above the pin axis A9 to block the pin axis A9.

[0013] In this embodiment, the side wall of the valve body 1 is equipped with an inspection door seat 5, and the inspection door seat 5 is equipped with an inspection door 7. The inspection door 7 is installed ...

Abstract

The invention discloses a gravity flap valve. The gravity flap valve comprises a valve body. Two turning plates which are horizontally and oppositely arranged are arranged in the valve body. The ends of the two turning plates are connected in a butt joint mode to form a right-angle structure. Sleeves are arranged at the other ends of the turning plates. Pin shafts A are fixedly arranged in the sleeves. The two ends of each pin shaft A extends outwards to be connected with the valve body in a rotating mode. Balance weight levers are fixedly arranged at the ends of the two pin shafts A. Balancing weights are arranged on the balance weight levers. The gravity flap valve is characterized in that arc-shaped baffles blocking the pin shafts A are arranged on the portion, located above the pin shafts A, of the valve body. The arc-shaped baffles are additionally arranged, materials which fall down can block the pin shafts A, the rotation of the turning plates is prevented from losing efficacy, and the gravity flap valve is mainly used as an industrial valve.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a gravity flap valve. Background technique [0002] At present, the traditional gravity flap valve has a valve body, and two flaps arranged opposite to each other are installed in the valve body. The ends of the two flaps are butted to form a right angle structure. Pin shaft A is arranged, and the two ends of pin shaft A protrude outwards and are connected with the valve body in rotation, and the ends of the two pin shafts A are fixedly equipped with counterweight rods, and counterweight blocks are housed on the counterweight rods. This traditional gravity flap valve is used for a long time, and the falling materials are prone to block the pin shaft A, causing the flap to fail to rotate. Therefore, it is very necessary to design a gravity flap valve that can well solve the above problems. Contents of the invention [0003] The object of the present invention is to improve the ...
