Abstract
The utility model discloses an automatic reset type ball valve which comprises a valve body, a sphere, a valve rod and a handle. An automatic reset mechanism installed between the valve rod and the handle comprises a restorer shell, a spindle and a reset spring, the spindle and the reset spring are installed inside the restorer shell, the upper end and the lower end of the spindle extend and penetrates out of the restorer shell, the handle is fixedly connected with the upper end portion of the spindle in sleeved mode, and the lower end of the spindle is fixedly connected with the upper end of the valve rod. One end of the reset spring is fixed with the inner wall of the restorer shell, the other end of the reset spring is fixed in the middle of the spindle, so that when a user rotates the handle, the reset spring connected with the spindle is gradually tightened, once the user loosens the handle, the reset spring releases compression force, and the handle is returned to an original position through reverse rotation of the spindle. Therefore, the automatic reset type ball valve effectively overcomes the defects that misoperation of the handle enables the valve not to be in a provision open position or a provision closed position, and eliminates safety accidents caused by misoperation of the valve.
Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of formula ball valve that automatically resets.
Background technique
Existing conventional ball valve mainly comprises valve body, spheroid, valve rod, handle, and spheroid is located in the valve body, and valve rod is arranged on the valve body; The lower end of valve rod is connected with the interior spheroid of valve body, and the upper end of valve rod passes outside the valve body, and the upper end of valve rod and handle Joint; The switch of ball valve mainly rely on manual pull that handle comes actuate valve stem and rotate with spheroid that valve rod fixes realize, but in the application of reality, usually occur because of artificial misoperation; Make ball valve not be in unlatching or the closed position of regulation and cause taking place technology or equipment accident; Particularly,, will cause irreparable damage in case misoperation takes place to must maintenance often opening or the ball valve of normally closed working state.At present, also have both at home and abroad enterprise to prevent misoperation through on the switch knob of valve, adding a location lock, get up complicated loaded down with trivial detailsly but open or close the location latching operation, and the location lock is long-term exposedly also loses effect because of reasons such as extraneous corrosions easily outside.
Summary of the invention
To the deficiency of existing technology, it is a kind of simple in structure, easy to operate and can effectively overcome the formula that the automatically resets ball valve of valve misoperation that the utility model provides.
For realizing above-mentioned purpose, the utility model provides a kind of formula ball valve that automatically resets, and comprises valve body, spheroid, valve rod, handle; Spheroid is located in the valve body, and valve rod is arranged on the valve body, and the lower end of valve rod is connected with spheroid; The upper end and the handle of valve rod link, and are equiped with automatic reset mechanism between valve rod and the handle, and described automatic reset mechanism comprises restorer housing, main shaft, Returnning spring; Described main shaft and Returnning spring are installed in the restorer housing; And the extension of the upper/lower terminal of main shaft passes outside the restorer housing, and socket is fixed with handle on the end, upper end of main shaft, the upper end Joint of the lower end of main shaft and valve rod; One end and the restorer inner walls of Returnning spring are fixed, and the other end of Returnning spring is fixed on the middle part of main shaft.
It is the clockwork spring type spring that the utility model can further be set to described Returnning spring.
The beneficial effect of the utility model is: adopt said structure, because the ball valve that the utility model provided is provided with automatic reset mechanism between its valve rod and handle; When therefore the user passed through the handle with sleeve opening/shutting valve, handle rotated and will drive the main shaft rotation, also just drove with the affixed valve rod of main shaft and reached the spheroid rotation that is connected with valve rod; And then the keying of realization valve; And in user's handle with sleeve process, the Returnning spring that is connected with main shaft will progressively tighten up, in case user's release handle; Returnning spring will discharge compressive force; Make handle be returned to initial position through the counter-rotating main shaft, be not in the position that regulation is opened or closed, also just eliminated the security incident that causes because of the valve misoperation thereby overcome effectively because of the handle misoperation causes valve.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1ly provided a kind of formula ball valve that automatically resets, comprised valve body 1, spheroid 2, valve rod 3, handle 4, spheroid 2 is located in the valve body 1; Valve rod 3 is arranged on the valve body 1, and the lower end of valve rod 3 is connected with spheroid 2, and the upper end of valve rod 3 and handle 4 link; Be equiped with automatic reset mechanism 5 between valve rod 3 and the handle 4, described automatic reset mechanism 5 comprises restorer housing 51, main shaft 52, Returnning spring 53, described Returnning spring 53 preferred clockwork spring type springs; Main shaft 52 is installed in the restorer housing 51 with Returnning spring 53; And the extension of the upper/lower terminal of main shaft 52 passes outside the restorer housing 51, and socket is fixed with handle 4 on the end, upper end of main shaft 52, the upper end Joint of the lower end of main shaft 52 and valve rod 3; One end of Returnning spring 53 and restorer housing 51 inwalls are fixed, and the other end of Returnning spring 53 is fixed on the middle part of main shaft 52.
Adopt said structure, because the ball valve that the utility model provided is provided with automatic reset mechanism 5 between its valve rod 3 and handle 4; When therefore the user passed through handle with sleeve 4 opening/shutting valves, handle 4 rotated and will drive main shaft 52 rotations, also just drove with main shaft 52 affixed valve rods 3 and reached spheroid 2 rotations that are connected with valve rod 3; And then the keying of realization valve; And in user's handle with sleeve 4 processes, the Returnning spring 53 that is connected with main shaft 52 will progressively tighten up, in case user's release handle 4; Returnning spring 53 will discharge compressive force; Make handle 4 be returned to initial position through counter-rotating main shaft 52, be not in the position that regulation is opened or closed, also just eliminated the security incident that causes because of the valve misoperation thereby overcome effectively because of handle 4 misoperations cause valve.
Claims (2)
1. the formula ball valve that automatically resets comprises valve body, spheroid, valve rod, handle, and spheroid is located in the valve body; Valve rod is arranged on the valve body, and the lower end of valve rod is connected with spheroid, and the upper end and the handle of valve rod link; It is characterized in that: be equiped with automatic reset mechanism between valve rod and the handle; Described automatic reset mechanism comprises restorer housing, main shaft, Returnning spring, and described main shaft and Returnning spring are installed in the restorer housing, and the extension of the upper/lower terminal of main shaft passes outside the restorer housing; Socket is fixed with handle on the end, upper end of main shaft; The upper end Joint of the lower end of main shaft and valve rod, an end and the restorer inner walls of Returnning spring are fixed, and the other end of Returnning spring is fixed on the middle part of main shaft.
