Abstract
The utility model relates to a quick-closing valve for a ship. The quick-closing valve for the ship comprises a valve body, a valve rod and a valve cover. The valve cover is connected and fixed with the valve body, the valve rod is arranged in the valve cover, and the valve rod, corresponding to the valve cover, can move up and down. A hand wheel is arranged at the upper end of the valve rod, a valve tray is arranged at the lower end of the valve rod, and the valve tray stretches into the valve body and is in sealed connection with the sealing face of the valve body. Threads are arranged on the upper portion of the valve rod, a spring is sleeved on the lower portion of the valve rod, the spring is arranged between the valve tray and the valve cover, a sliding cavity is arranged in the valve cover, a hexagonal nut is arranged in the sliding cavity and is connected with the valve cover through a locking mechanism, and the valve rod can move up and down through the hexagonal nut. After the locking mechanism is unlocked, the hexagonal rapidly slides under the effect of spring force, and the aim that the valve tray is sealed with the valve body is achieved. A rapid locking mechanism is composed of an air cylinder, a connection rod, a positioning pin and the hexagonal nut, and the quick-closing valve for the ship can achieve quick closing through the locking mechanism and the spring. The quick-closing valve for the ship is convenient to control, can quickly close a valve door in emergent conditions, saves emergency rescuing time and avoids loss expanding.
Description
Technical field
The utility model relates to valve, especially a kind of fast valve peculiar to vessel that can quick closedown.
Background technique
At present, existing stop valve peculiar to vessel generally is common cock-type or flat stifled formula structure, and material mainly is cast iron, and existing stop valve exists valve mechanism complicated usually, and intensity is not high, and is not wear-resistant, easy to leak, the shortcoming such as working life is short.Existing stop valve peculiar to vessel is normally realized opening or closing valve by rotating handwheel, and operating process is not only required great effort, and consuming time longer, if run into the situation that needs the emergency cut-off valve, this valve tends to delay and speedily carries out rescue work the time, and expansion causes damage.
The model utility content
For the deficiency of above existing ship with stop valve, the purpose of this utility model provides a kind of fast valve peculiar to vessel that can realize quick closedown.
The purpose of this utility model is achieved by the following technical solution:
Fast valve peculiar to vessel, comprise valve body, valve rod and valve gap, valve body is provided with import and outlet, and the top and valve body that valve gap is located at valve body is connected and fixes, valve rod be located in the valve gap and relatively valve gap move up and down, the valve rod upper end is provided with handwheel, the valve rod lower end is provided with valve disc, and valve disc extend in the valve body and is tightly connected with valve body sealing surface formation, and described valve rod top is provided with screw thread, stem lower portion is arranged with spring, and spring is located between described valve disc and the valve gap;
Be provided with sliding cavity in the described valve gap, be provided with thread bush in the sliding cavity, thread bush is connected with valve gap by locking positioning mechanism, and valve rod can move up and down along valve rod axis by thread bush; After described locking positioning mechanism is removed being connected of thread bush and valve gap, thread bush downward quick sliding under the effect of described spring force, thereby the sealing of realization valve disc and valve body.
As optimal technical scheme of the present utility model, described locking positioning mechanism comprises cylinder, connecting rod and locating stud, and described thread bush is provided with location cotter way or positioning hole, and described cylinder is realized locking location or the release of double thread cover by connecting rod push-and-pull locating stud.
As optimal technical scheme of the present utility model, described thread bush is hexagon nut, and the sliding cavity of described valve gap is made as six structures.
The beneficial effects of the utility model are: with respect to prior art, the utility model adopts cylinder, connecting rod, locating stud and hexagon nut to consist of the quick locking positioning means, six structures of valve gap sliding cavity can guarantee that hexagon nut slides up and down smoothly, limits the rotation of hexagon nut simultaneously in sliding cavity; Open the operation of valve and still undertaken by rotation hand wheel, realize rapid-closure damper by locking positioning mechanism and spring when closing valve.The utility model control is convenient, and in case of emergency, the energy rapid-closure damper is saved and speedily carried out rescue work the time, avoids loss to enlarge.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is structural representation of the present utility model.
