Description

Stop valve with manual emergency function Technical Field The utility model relates to a stop valve, in particular to a stop valve with a manual emergency function, which can realize the opening and closing of a valve through manual operation when an electric system fails. Background When the automobile is reversed, acting force is generated between traction hooks of the main trailer, at the moment, the inertial main cylinder has output pressure, and the trailer can generate braking phenomenon, so that adverse effect on reversing is achieved. On good road surfaces, the adverse effect is negligible because the rolling assistance of the tires is small, but if the tires are in pits during reversing, a large acting force is generated between the traction hooks of the main trailer, and the braking effect of the corresponding trailer is also increased, which is extremely unfavorable for reversing. The reversing stop valve is respectively connected with the trailer inertia master cylinder and the brake in a switching way, and when the tractor is in reverse gear, the stop valve is powered on and closed to prevent brake fluid from entering the brake cylinder from the trailer inertia master cylinder. The reverse stop valve can effectively avoid such adverse effects. The existing reversing stop valve is generally suitable for civil automobiles, and the reliability and environmental adaptability of civil products cannot meet the military requirements. Disclosure of utility model The utility model aims to solve the technical problem of providing the stop valve with the manual emergency function, integrates an electric driving mode and a manual driving mode, improves emergency capacity and can meet the military requirement. In order to solve the technical problems, the utility model adopts the following technical scheme: A stop valve with a manual emergency function comprises a valve body, wherein an oil duct is arranged in the valve body, one side of the oil duct is communicated with the outside through an oil inlet, the other side of the oil duct is communicated with the outside through an oil outlet, a manual throttle valve and an electromagnetic valve are respectively arranged outside the valve body, and the manual throttle valve and the electromagnetic valve are used for manually or automatically disconnecting or communicating the oil duct. The oil duct comprises a manual oil inlet duct and a manual oil outlet duct, one end of the manual oil inlet duct is communicated with the oil inlet, the other end of the manual oil inlet duct is communicated with the inlet of the manual throttle valve, one end of the manual oil outlet duct is communicated with the outlet of the manual throttle valve, the other end of the manual oil outlet duct is communicated with the transition flow passage, the transition flow passage is communicated with the upper part of the installation passage, the valve core of the electromagnetic valve is arranged in the installation passage, and the lower end of the installation passage is communicated with the oil outlet. The valve body is made of an aluminum alloy material. The outer surface of the valve body is anodized. The manual throttle valve, the electromagnetic valve and the valve body are detachably installed, and the joint is sealed through a sealing ring. The transition runner is horizontally arranged, one side of the transition runner is communicated with the outside, and one end of the transition runner, which is communicated with the outside, is screwed into the plug through a screw cap. And the manual throttle valve and the electromagnetic valve are both standard components. The utility model provides a stop valve with a manual emergency function, which has the following technical effects: 1) The electromagnetic valve and the manual throttle valve are arranged on the oil duct of the valve body, compared with a traditional stop valve, the manual throttle valve is added, so that the product has the function of manually closing an oil way, and even if the electromagnetic valve fails accidentally, the product can work normally, and the reliability is improved. 2) The device (reversing stop valve) is mainly applied to a military tractor, the valve body is made of an aluminum alloy material, surface anodic oxidation treatment is carried out, and the outer surfaces of other parts are galvanized with nickel, so that the device can adapt to various severe environments, the salt spray resistance is improved to 256h, the protection level is IP67, and adverse effects on reversing are eliminated.
