Description
Technical Field
The utility model relates to the technical field of valves, in particular to a marine double-stop valve.
Background
The stop valve is a valve with a closing member moving along the center line of a valve seat, has the function of stopping or connecting working media in a pipeline, can also adjust the flow of the working media, and is widely applied. The marine stop valve is a marine valve, needs to meet the environmental conditions of ships, is used for controlling the stop or connection of fluid in a ship pipeline, and is mainly applied to a ship hydraulic oil circuit system. When an oil circuit system cannot work normally, the existing marine stop valve cannot switch the oil circuit system which does not work normally under the normal working condition of a steering engine, and the flow regulation performance is poor. In order to solve the technical problems, scientific research institutes and scientific personnel of enterprises are continuously researching and researching, and it is desirable to design a marine double-stop valve which has stronger flow regulation performance and can switch off an oil way system which does not normally work under the normal working condition of a steering engine.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects and provide the marine double-stop valve which is strong in flow regulation performance and can be switched to an oil way system which does not work normally under the condition that a steering engine works normally. The design of two regulating levers, hydraulic oil pressure control range is wide, has improved flow control performance. The oil inlet is shared, the 2 independent outlet flanges are respectively connected into the two sets of oil circuit systems, and when one of the oil circuit systems cannot work normally, the oil circuit system which does not work normally can be switched off under the normal working condition of the steering engine, so that the normal operation of the hydraulic system of the steering engine is ensured.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a marine double-stop valve comprises a left manual adjusting rod, a left adjusting valve sleeve, a left conical valve core, a first outlet flange, a valve body, a second outlet flange, a right conical valve core, a right manual adjusting rod, a right adjusting valve sleeve, an oil inlet and a fixing bolt.
Preferably, the first outlet flange is provided with 4 connecting holes.
Preferably, the valve body is made of stainless steel material.
The technical principle adopted by the utility model is as follows: when the left manual adjusting rod is rotated anticlockwise, the left manual adjusting rod drives the left conical valve core to move leftwards, the valve is in an open state, hydraulic oil can circulate, the left manual adjusting rod is rotated clockwise, and the left manual adjusting rod drives the left conical valve core to move rightwards, so that the hydraulic oil circulation stopping effect is achieved. When the right manual adjusting rod is rotated, the right manual adjusting rod drives the right conical valve core to move, so that the valve is in an opening and stopping state. The design of two regulating levers, hydraulic oil pressure control range is wide, has improved flow control performance. The oil inlet is shared, the 2 independent outlet flanges are respectively connected into the two sets of oil circuit systems, and when one of the oil circuit systems cannot work normally, the oil circuit system which does not work normally can be switched off under the normal working condition of the steering engine, so that the normal operation of the hydraulic system of the steering engine is ensured.
Compared with the prior art, the utility model has the beneficial effects that:
the double-adjusting-rod hydraulic pump has the advantages that the double-adjusting-rod hydraulic pump is designed, the hydraulic oil pressure adjusting range is wide, and the flow adjusting performance is improved. The oil inlet is shared, the 2 independent outlet flanges are respectively connected into the two sets of oil circuit systems, and when one of the oil circuit systems cannot work normally, the oil circuit system which does not work normally can be switched off under the normal working condition of the steering engine, so that the normal operation of the hydraulic system of the steering engine is ensured. The valve body is made of stainless steel materials, and the service life of the valve body is prolonged.
