Problems solved by technology

It may be necessary to empty the oil in the hydraulic oil tank during maintenance of the hydraulic system. Due to the large volume of the hydraulic oil tank of the mining dump truck, the volume of the hydraulic oil tank of the large-tonnage mining dump truck can reach more than 1,000 liters, and it is time-consuming and laborious to empty the hydraulic oil tank. The time of draining and refilling is longer than the maintenance process, and there is a risk of hydraulic oil being contaminated during the process of draining and refilling the hydraulic oil

Embodiment Construction

[0023] The present invention will be further described below according to the accompanying drawings and embodiments.

[0024] Such as Figure 1 to Figure 3 As shown, an integrated butterfly valve includes a valve body 9 , a valve plate 7 , a rotating shaft 4 and a handle 1 . Such as figure 1 As shown, the valve body 9 includes two end faces. When in use, the left end face of the valve body 9 is in contact with the tank mouth end face of the hydraulic oil tank. The valve body 9 is also provided with a sealing ring on the left end face to play a sealing role. Avoid oil leakage at the connection between the valve body 9 and the hydraulic oil tank, and the right end surface of the valve body 9 is connected with the hydraulic hose of the hydraulic system. Port 9-1; oil port 9-1 is used to connect the oil port of the hydraulic oil tank with the hydraulic hose, so that the hydraulic oil in the hydraulic oil tank can be sent into the hydraulic hose through the oil port 9-1 to provid...

Abstract

The invention belongs to the field of hydraulic components, and particularly relates to an integrated butterfly valve which comprises a valve body, a valve plate, a rotating shaft and a handle, and an oil port penetrating through the two end faces of the valve body is formed in the valve body; the rotating shaft penetrates into the valve body from the side face of the valve body and penetrates through the oil port to be supported in the valve wall of the valve body. The valve plate is arranged in the oil port and is connected with the rotating shaft; the rotating shaft outside the valve body is connected with the handle; a magnetic induction switch upper portion is arranged on the handle, a magnetic induction switch lower portion inducting the magnetic induction switch upper portion is arranged on the side face of the valve plate, and the magnetic induction switch lower portion is in signal connection with a mining dump truck controller. A mounting hole I and a mounting hole II are formed in the end face, located on one side of the oil port, of the valve body. When the valve plate is perpendicular to the axial center line of the oil port, the butterfly valve is in a closed state. Before maintenance, the hydraulic oil tank is physically isolated from elements connected with the hydraulic oil tank, so that maintenance of the hydraulic system is facilitated, and hydraulic oil in the hydraulic oil tank does not need to be emptied.

Description

technical field [0001] The invention belongs to the field of hydraulic components, in particular to an integrated butterfly valve. Background technique [0002] Mining dump truck refers to a special load-carrying vehicle used for short-distance transportation on special roads such as open-pit mines or large-scale civil construction sites to complete the tasks of rock and earth stripping and ore transportation. Widely used in various open-pit mines, hydropower projects, railway and highway construction projects and large-scale construction projects. It may be necessary to empty the oil in the hydraulic oil tank during maintenance of the hydraulic system. Due to the large volume of the hydraulic oil tank of the mining dump truck, the volume of the hydraulic oil tank of the large-tonnage mining dump truck can reach more than 1,000 liters. It is time-consuming and laborious to empty the hydraulic oil tank. The time of draining and refilling is longer than the maintenance proces...
