Abstract
The utility model relates to a turning spherical stop valve, which comprises a valve body, and the valve body is provided with a water inlet and a water outlet. The utility model is characterized in that spherical valve core is arranged in the valve body, and the spherical valve core is arranged on a shifting fork via a pin shaft; the spherical valve core is contacted with a spherical surface of a valve port, and the shifting fork is fixed on a main control shaft which arranged on the valve body and is connected with a servo mechanism. The utility model has the advantages of simple structure, easiness for opening and closing the valve port, high fit precision between the valve core and the valve port, favorable sealing performance, no leakage, long service life, automatic opening and closing due to the connection with the servo mechanism, etc.
Description
Technical field
The utility model relates to valve field, is a kind of convertible spherical stop valve, is specially adapted to be connected with servomechanism the convertible spherical stop valve of realizing closing automatically, opening valve port.
Background technique
Existing flashboard type stop valve is by valve body and the flashboard that is provided with in valve body, and flashboard and threaded stem connect to form.This valve makes upper and lower the moving of flashboard realize cutting out or opening valve port by rotary valve rod, and its deficiency is, because of flashboard cooperates for the side face friction pair joins with inner valve body, closes, opens the valve port effort; Because of valve rod is threaded with flashboard, often because of thread damage or loosening, and flashboard is separated with valve rod, flashboard is in the close port position, and can not open valve port, and working life is low; Because of flashboard and inner valve body serious wear, sealing is poor, easily produces and leaks; This valve can not be connected with servomechanism, can not realize closing automatically and opening of valve port.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, closes, to open valve port easy, spool and valve port quality of fit height, good airproof performance does not leak, long service life can be connected with servomechanism, realizes closing automatically, opening the convertible spherical stop valve of valve port.
The technological scheme that solves its technical problem employing is, a kind of convertible spherical stop valve, it comprises valve body, on valve body, be provided with entery and delivery port, its special way is: be provided with spherical valve core in valve body, spherical valve core is loaded on the shift fork by bearing pin, and spherical valve core contacts with the valve port sphere, and shift fork is fixed on the master axis that is provided with on the valve body with servomechanism is connected.
Convertible spherical stop valve of the present utility model, stir the structure that the sphere valve port that matches with it was closed or opened to spherical valve core owing to adopt master axis by shift fork, it is simple in structure, and spool cooperates with the valve port sphere, the quality of fit height, good airproof performance, not easy to wear, do not leak long service life, master axis is connected with servomechanism, can realize closing and opening of autocontrol valve mouth.
Description of drawings
Fig. 1 is convertible spherical stop valve structure cross-sectional schematic.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
With reference to Fig. 1 and 2, convertible spherical stop valve has valve body 1, on valve body 1, be provided with entery and delivery port 8,9, in valve body 1, be provided with spherical valve core 3, spherical valve core 3 contacts with valve port 10 spheres, spherical valve core 3 is connected with fork 2 by bearing pin 4, and fork 2 is fixed on setting and master axis 6 that servomechanism 7 is connected on the valve body 1, is provided with seal ring 5 at master axis 6 and valve body 1 cooperation place.The valve body 1 of present embodiment, shift fork 2, master axis 6, the bearing pin 4 best stainless steels that adopt are made, and spherical valve core 3 adopts nylon material to make.The servomechanism 7 that master axis 6 connects is the commercially available prod, is the technology that those of ordinary skills are familiar with.
