Abstract
The utility model relates to a leakage-proof valve, belonging to the technical field of the class of valves. The utility model relates to a valve used in a liquid (gas) pipe. The utility model is composed of an upper valve body, a lower valve body and a valve rod. The utility model is characterized in that the lower end of the valve rod is provided with a conical valve plug cooperated with a conical valve opening arranged in the lower valve body; a corrugated pipe is arranged on the valve rod. The utility model has the advantages of simple structure, good closing performance and quick on-off. The utility model can not easily be damaged.
Description
The utility model belongs to valve class technical field.
The valve that is used for liquid (gas) pipeline in the prior art is made up of valve body and valve rod, flap, and valve rod and valve body are screw-thread fit, and this kind valve seal is poor, and is fragile.
The purpose of this utility model provides a kind of good seal performance, easy to operate, non-damageable leakproof valve.
The purpose of this utility model is finished like this: it is formed by connecting by upper and lower two valve bodies and valve rod, and there is a through hole at the upper valve body center, in order to valve rod to be installed, following valve body is one to have the cavity of valve port, and the valve rod lower end is a valve plug, and valve plug is a cone, cooperate with the taper valve port, there is bonnet the upper valve body upper end.
The utility model can be used as manually operated valve, also can be used as foot valve.
Fig. 1 is a manually operated valve structural representation of the present utility model
Fig. 2 is a foot valve structural representation of the present utility model
Describe in detail below in conjunction with accompanying drawing
With reference to Fig. 1,1 is following valve body among the figure, and following valve body is connected with upper valve body 2, valve rod 6 is installed at upper valve body 2 centers, valve rod 6 lower ends are cone-shaped valve plugs 4, and valve rod 6 upper ends laterally have hole 11, pin 9 can patchhole 11 in, with location valve rod 6, bellows 5 upper ends are sealedly connected on upper valve body 2 lower ends, and its lower end is sealedly connected on the valve rod 6, and following valve body 1 is connected with pipeline, have taper valve port 3, cone-shaped valve plug 4 cooperates with valve port; There is bonnet 7 upper valve body 2 upper ends, with upper valve body 2 for being threaded.When present embodiment is used for gas, liquid pipeline, can will descend valve body directly to insert pipeline, when bellows 5 is in free state, valve plug sealing valve port, and owing to feed liquor (gas) mouth pressure make close tightr, last poppet-valve bar 6, and sell and go up pin 9, can keep opening state.(the moving direction of stream is for from top to bottom for the liquid of present embodiment.
With reference to Fig. 2,1 is following valve body among the figure, and following valve body is connected with upper valve body 2, valve rod 6 is installed at upper valve body 2 centers, valve rod 6 lower ends are cone-shaped valve plugs 4, and valve rod 6 upper ends are provided with Returnning spring 8, and the upper end of Returnning spring 8 withstands on valve rod 6 tops, the lower end withstands on the upper end of upper valve body 2, bellows 5 upper ends are sealedly connected on upper valve body 2 lower ends, and its lower end is sealedly connected on the valve rod 6, and following valve body 1 is connected with pipeline, have taper valve port 3, cone-shaped valve plug 4 cooperates with taper valve port 3; There is bonnet 7 upper valve body 2 upper ends, and bonnet 7 lower end installing and locating circles 10 with stupefied cooperation of upper valve body 2 upper end edges, make bonnet 7 unlikely coming off.The lower end of following valve body 1 is provided with bottom flange (12), is beneficial to install; Present embodiment in use, liquid (gas) direction flows from bottom to top.
The utility model is simple in structure, and it is good to close performance, and not fragile, switch is fast.
