Abstract
A ball valve with the check function is composed of a valve body, a valve deck, a ball body, a valve seat, a valve rod, a piston, a connecting rod, a fixed disc and a spring. The valve body is fixedly connected with the valve deck through a bolt, the valve seat is arranged in the valve body, the ball body can be placed in the valve seat, a groove is formed in the top end of the ball body, the bottom end of the valve rod can be embedded in and fixedly placed in the groove, the fixed disc is arranged in a pipeline of the valve deck, a through hole is formed in the center of the fixed disc, the connecting rod can stretch into the through hole, a fixed piece is arranged at one end of the connecting rod, the spring can be fixed between the fixed disc and the fixed piece, the other end of the connecting rod is connected with the piston, and the connecting rod and the piston are formed integrally. The piston is arranged on a protrusion arranged in the pipeline of the valve deck, the piston is tightly attached to the protrusion, and flow of media can be blocked by the piston. The ball valve has the advantages of being simple in structure and convenient to mount and having the check function.
Description
Technical field
The utility model relates to ball valve, is specifically related to a kind of ball valve with check function.
Background technique
Ball valve is a kind of flow direction that cuts off, distributes and change medium that is used for making, and is to make valve unimpeded or inaccessible by rotatable handle, and switch is light.Ball valve can be widely used in water supply line, and in the time of water supply cut, the water in pipeline refluxes, and the pressure producing that refluxes easily causes Pipeline damage.
Model utility content
The purpose of this utility model is to provide a kind of ball valve with check function, has simple in structurely, is convenient to the advantages such as installation, and with check function.
The utility model adopts following technological scheme:
With a ball valve for check function, formed by valve body, valve gap, spheroid, valve seat, valve rod, piston, connecting rod, fixed tray and spring.
Described valve body and valve gap are bolted to connection, and are provided with a valve seat in valve body, and spheroid can be placed in valve seat, and described spheroid top has a groove, valve rod bottom can embed and fixed in position in groove.
In a described valve gap pipeline, be provided with a fixed tray, described fixed tray center has a through hole, and connecting rod can be stretched in through hole.One end of described connecting rod is provided with fixed plate, spring can be fixed between fixed tray and fixed plate, and the connecting rod the other end is connected with piston, and connecting rod and piston are with being integrated.
Described piston is placed in the high spot being provided with in valve gap pipeline, and piston is close to high spot, makes piston can block medium circulation.
The utility model has the advantages that: simple in structure, be convenient to install, and there is check function.
Accompanying drawing explanation
Fig. 1 is complete section structural representation of the present utility model.
Wherein: 1. valve body, 2. valve gap, 3. spheroid, 4. valve seat, 5. valve rod, 6. piston, 7. connecting rod, 8. fixed tray, 9. spring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of release ball check valve, is made up of valve body 1, valve gap 2, spheroid 3, valve seat 4, valve rod 5, piston 6, connecting rod 7, fixed tray 8 and spring 9 the utility model.
Described valve body 1 is bolted to connection with valve gap 2, is provided with a valve seat 4 in valve body 1, and spheroid 3 can be placed in valve seat 4, and described spheroid 3 tops have a groove, valve rod 5 bottoms can embed and fixed in position in groove.
In described valve gap 2 pipelines, be provided with a fixed tray 8, described fixed tray 8 centers have a through hole, and connecting rod 7 can be stretched in through hole.One end of described connecting rod 7 is provided with fixed plate, spring 9 can be fixed between fixed tray 8 and fixed plate, and connecting rod 7 the other ends are connected with piston 6, and connecting rod 7 is integrated with piston 6 is same.
Described piston 6 is placed in the high spot being provided with in valve gap 2 pipelines, and piston 6 is close to high spot, makes piston 6 can block medium circulation.
In the time of driving handle 90-degree rotation, spheroid 3 passages and pipeline communication, MEDIA FLOW, through the through hole of fixed tray, moves right the pressure promotion piston 6 of medium, thereby makes medium circulation; In the time of water supply cut, spring 9 resets, and makes piston 6 be close to the high spot being provided with in valve gap 2 pipelines, prevents medium back flow thereby block passage, plays non-return effect.
