Abstract
The utility model relates to a no-leakage valve rod for a valve body, which is arranged on a water valve and an IC card intelligent fuel gas pipeline and uses an IC card for controlling a switch of a natural gas, liquefied gas or coal gas pipeline. The structure is that a spring (5) is connected with a spherical connecting rod axle (1), the spherical surface of the spherical connecting rod axle (1) is connected with a rubber pad (3), and the rubber pad (3) is fixed on a valve body (4). The utility model has the advantages that in work, a spring on a positioning pin pushes the spherical connecting rod axle of which the spherical surface is pushed to the rubber pad for seal. Thus, when the pressure is higher, the sealing performance is better and the leakage rate is lower. The rotating force of the spherical connecting rod axle is low, and even the spherical connecting rod axle rotates for a long time, the abrasion of the spherical surface of the spherical connecting rod axle or the abrasion of the rubber pad can not have leakage. In addition, the utility model has the characteristics of simple and reasonable entire structural design, long service life, low cost, etc.
Description
Technical field
The utility model relates to and a kind ofly be installed on water valve and the IC-card intelligent gas and control valve body Leakless valve bar on rock gas, liquid gas, the gas piping switch with IC-card.Belong to electric-controlled ball valve and manually-operated gate technical field.
Background technique
What adopted on the existing valve body valve rod is O shape circle, because it can not compress, so it is easy to leak, if compressed, the rotatory force that it produced is very big, also is easy to wearing and tearing after long-time the use, and causes leakage during use.Also useful Tao Zhi valve rod in the prior art, however the Tao Zhi valve rod used, and the precision requirement of its cost height, processing is also high, processing is improper a little is easy to break.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of good seal performance, antileakaging valve body Leakless valve bar.Technical solution of the present utility model: its structure is that spring links to each other with the spherical connecting bar axle, and the sphere of spherical connecting bar axle links to each other with rubber pad, and rubber pad is fixed on the valve body.Advantage of the present utility model: the spring on the locating stud promotes the spherical connecting bar axle when work, yet the sphere by the spherical connecting bar axle is pushed to realization sealing on the rubber pad again, the big more sealing effect of its pressure is good more, can not leak more, and the power that the spherical connecting bar axle rotates is quite little, the spherical pitman shaft of long-time rotation, even the sphere abrasion of spherical rod shaft or rubber gasket abrasion, leakage phenomenon can not take place, this mainly is the effect that spring pushes away forward, because spring can be passed forward, be impossible so leak, the power of its rotation is also quite light simultaneously.Also sign an undertaking characteristics such as structure advantages of simple, long service life, cost be low of the utility model in addition.
Description of drawings
Accompanying drawing is an example structure schematic representation of the present utility model.
Among the figure 1 is spherical connecting bar axle, the 2nd, rubber pad pressing plate, the 3rd, rubber pad, the 4th, valve body, the 5th, spring, the 6th, locating stud, the 7th, fan-shaped pylone plate.
Embodiment
Main structure is that spring 5 links to each other with spherical connecting bar axle 1, and the sphere of spherical connecting bar axle 1 links to each other with rubber pad 3, and rubber pad 3 is fixed on the valve body 4.
The contrast accompanying drawing, it comprises spherical connecting bar axle 1, rubber pad pressing plate 2, rubber pad 3, valve body 4, spring 5, locating stud 6, fan-shaped pylone plate 7, wherein establish locating stud 6 in the fan-shaped pylone plate 7, spring 5 in locating stud 6 and the spherical connecting bar axle 1 is connected, spring 5 links to each other with spherical connecting bar axle 1, the sphere of spherical connecting bar axle 1 links to each other with rubber pad 3, and rubber pad 3 links to each other with rubber pad pressing plate 2 and is fixed on the valve body 4.Spherical connecting bar axle 1 is following facing cut limit, the center of milling the limit has an aperture can put spring 5, open little being pickled with grains or in wine in the 90 degree directions of milling the place, limit simultaneously, can put locating stud 6, and the spherical connecting bar axle is the plane below 1 centre, shape top spherical in shape in the middle of the spherical connecting bar axle 1, its top are opened poor in order to connect other parts.
Mainly be that spring on the locating stud promotes the spherical connecting bar axle and the sphere of spherical connecting bar axle is pushed to and seals on the rubber pad, so pressure is big does not more leak more, and the power that the spherical connecting bar axle rotates is also very little, the spherical pitman shaft of long-time simultaneously rotation, if have the sphere abrasion of spherical rod shaft or the words of rubber gasket abrasion also not to leak, because because the effect that spring pushes away forward, it can be passed forward, can absolutely not leak thus, the power of Zhuan Donging is also quite light simultaneously.
