New-type finalized vulcanizer overflow control valve

Abstract

The invention relates to a novel excess flow valve of a tire forming vulcanizer, which is mainly used for controlling water coming in or out a water cylinder of the tire forming vulcanizer. The novel excess flow valve comprises a valve body (1), a piston (9), a cylinder rod (3) and a valve cover (8). The valve body (1) has an integrated structure, a piston hole (1.4) and a cylinder rod hole (1.3) are axially formed on the center of the valve body (1), an O-shaped sealing ring I is embedded between the cylinder rod (3) and the cylinder rod hole (1.3), an O-shaped sealing ring II is arranged between the piston (9) and the piston hole (1.4), one side of the valve body (1) is provided with a water outlet (1.1), one end of the valve body is provided with a water inlet (1.2), the other end of the valve body (1) is provided with the valve cover (8), an air inlet (8.1) is axially arranged on the center of the valve cover (8), the other side of the valve body (1) is provided with an air outlet (1.5), the valve cover (8) and the valve body (1) are fixedly connected, an O-shaped sealing ring III (5) is embedded between the hole walls of the valve cover (8) and the piston hole of the valve body (1) to seal. The novel excess flow valve has the advantages of small volume, light weight, good sealing performance and good closing performance.

Description

technical field [0001] The invention relates to a control valve, in particular to an overflow control valve of a novel tire shaping vulcanizer. It is mainly used to control the water in and out of the water tank of the tire shaping vulcanizer. It belongs to the technical field of control components. Background technique [0002] The overflow control valve of the new type tire shaping vulcanizer is a control part for water in and out of the water tank. Before the present invention was made, what the overflow control valve that is used for novel tire shaping vulcanizing machine adopted at present is a kind of split structure, mainly is made up of cylinder body, cylinder body and piston rod. The cylinder body and cylinder body are connected by threads, and the seal ring is used to seal the two, and the piston rod and cylinder body are made of the same material. It mainly has the following deficiencies: [0003] 1. The cylinder body and the cylinder body are connected by thr...

AI Technical Summary

Problems solved by technology

[0003] 1. The cylinder body and the cylinder body are connected by threads, and a sealing ring is used in the middle to seal, the sealing performance is poor, and leakage is easy to occur

[0004] 2. Since the cylinder body and the cylinder body are split, the overflow valve is bulky and heavy, which increases the cost of manufacture and use

[0005] 3. The piston rod and the barrel are made of the same material. When the valve is opened and closed, it is easy to rough the port, causing the valve to not close tightly, causing leakage, resulting in unstable back pressure of the water tank, crushing the mold, and resulting in waste tires
