Abstract

The utility model relates to a cone-shaped check valve which comprises an inverted cone valve body. A movable cone-shaped piston is installed at the opening at the bottom of the valve body, the maximum diameter of the piston is greater than the diameter of the opening of the bottom of the valve body, both the lower end of the piston and the opening of the bottom of the valve body are provided with hanging holes, and the hanging hole of the piston is connected with the hanging hole of the bottom of the valve body through a hanging rope. The movable cone-shaped piston is installed in the cone-shaped check valve, and therefore service life of the cone-shaped check valve is prolonged greatly.

Description

Tapered safety check
Technical field
The utility model relates to a kind of tapered safety check.
Background technique
Traditional check valve structure complexity, manufacture cost is higher, and using effect also has and has a greatly reduced quality after long-time the use.
The model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of tapered safety check, solve general check valve short problem in working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of tapered safety check, comprise the inverted cone valve body, valve body bottom opening place is provided with mobilizable tapered piston, the piston maximum diameter is greater than valve body bottom opening place diameter, piston lower end and valve body bottom opening place have all offered hanging hole, and the hanging hole of piston is connected with valve body bottom hanging hole by lanyard.
The beneficial effects of the utility model are to be provided with movable tapered piston in the tapered safety check of the present utility model, thereby to have prolonged the working life of safety check greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. valve bodies, 2. piston among the figure.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of tapered safety check as shown in Figure 1, comprise inverted cone valve body 1, valve body 1 bottom opening place is provided with mobilizable tapered piston 2, piston 2 maximum diameters are greater than valve body 1 bottom opening place diameter, piston 2 lower ends and valve body 1 bottom opening place have all offered hanging hole, and the hanging hole of piston 2 is connected with valve body 1 bottom hanging hole by lanyard.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
