Problems solved by technology

Since construction machinery mostly works in the open air, the harsh working environment often causes dust to enter the gap between the valve body and the valve body from the gap between the rotating valve core and the valve body, resulting in oil leakage of the stop valve or stuck valve core.

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0014] Embodiment of the present invention: when making the cut-off valve, a kind of dust-proof method for the cut-off valve of the present invention is used to make the cut-off valve. When performing dust protection on the rotary spool of the globe valve, the dust-proof rubber ring is placed on the upper end of the rotary spool of the globe valve so that the dust-proof rubber ring is flush with the upper end surface of the valve body of the globe valve. This method can be effective. To prevent dust from entering the valve body from the gap between the rotating valve core and the valve body.

[0015] The structure of a dust-proof shut-off valve of the present invention made according to the above method is as follows: figure 1 As shown, the dust-proof globe valve includes an existing ...

Abstract

The invention discloses a dust control method of a shutoff valve and a dustproof shutoff valve. The method comprises the following steps that: a dustproof rubber ring is adopted for preventing dust; the dustproof rubber ring is arranged at the upper end of a rotary valve core of the shutoff valve when the dustproof rubber ring is arranged on the rotary valve core of the shutoff valve to prevent dust, so the dustproof rubber ring is parallel and level to the upper end face of the valve body of the shutoff valve. With the adoption of the method, the dust can be effectively prevented from entering inside the valve body from a gap between the rotary valve core and the valve body. The dustproof shutoff valve has the advantages that the dustproof effect is good, the service life is long, and the work performance is reliable, and also has the advantages that the use efficiency of engineering machinery can be improved, and good economic efficiency can be brought.

Description

technical field [0001] The invention relates to a dust-proof method for a shut-off valve and a dust-proof shut-off valve, belonging to the technical field of hydraulic shut-off valve production. Background technique [0002] The stop valve is usually used in the pipeline of the hydraulic system. By manipulating the rotation of the spool, the pipeline oil of the hydraulic system is in the on-off state. [0003] Globe valves are often used in the pipelines of construction machinery hydraulic systems. The globe valve consists of a valve body, which is provided with a core hole, and a rotating valve core is provided in the core hole; there are interface threaded holes at both ends of the valve body, and a through hole is provided on the rotary valve core corresponding to the interface threaded hole, and the rotation One end of the spool is provided with a dust-proof ring. The current dust-proof ring and the core hole of the valve body are not provided with a dust-proof rubber ...
