Abstract

The no-leakage spherical valve rod has the structure comprising spherical link rod shaft with spherical surface contacting closely with the end surface of the holding rubber plate with O-ring, planar bearing contacting with the holding rubber plate, planar bearing holding plate on the planar bearing, positioning pin inserted inside the spherical link rod shaft, and fan-shaped positioning plate together with the holding rubber plate set on the valve body. The present invention has the advantages of excellent sealing performance, simple and reasonable structure, long service life, low cost, etc.

Description

No-leakage spherical valve rod
Technical field
What the present invention relates to is a kind of being installed on IC-card intelligent gas and the IC-card intelligence water valve, and controls valve body---no-leakage spherical valve rod on rock gas, hydraulic pressure gas, the gas piping switch with IC-card.Belong to electrically-controlled valve and manually-operated gate technical field.
Background technique
What adopted on the existing valve body valve rod is that park pin and O type circle cooperate, because it can not press De Taisong, pine is easy to leak during use, if press tension, the rotatory force that it produced is very big, also is easy to wearing and tearing after long-time the use, is caused leakage by wearing and tearing.Also useful ceramic valve rod in the prior art, yet the cost height of ceramic valve rod, the required precision of processing is also high, and difficulty of processing is big, improperly a little is easy to break.
Summary of the invention
The objective of the invention is to the defective at above-mentioned existence, propose a kind of no-leakage spherical valve rod, it has good seal performance, is difficult for characteristics such as leakage.Technical solution of the present invention, it is characterized in that comprising the spherical connecting bar axle, the rubber pad pressing plate, plane bearing, the plane bearing pressing plate, protect the tower spring, locating stud, fan-shaped positioning plate, valve body, wherein the spherical connecting bar axle is by the through hole of rubber pad pressing plate, the end face that has disjunctor O shape circle on the sphere that makes the spherical connecting bar axle and the rubber pad pressing plate is close to and is linked to each other, plane bearing is close to the top of rubber pad pressing plate by the spherical connecting bar axle, the plane bearing pressing plate is arranged on the plane bearing by spherical rod shaft, guarantor's tower spring is pressed on the plane bearing pressing plate by the axle of spherical connecting bar axle, the horizontal bolt of locating stud is on the axle of the spherical connecting bar axle that has cross-drilled hole, fan-shaped positioning plate is placed in the middle of the locating stud by the axle of spherical connecting bar axle, and fan-shaped positioning plate and rubber pad pressing plate are fixed on the valve body.
Advantage of the present invention, during work, the sphere of spherical connecting bar axle, with continuous being close to of O type circle end face that rubber pad presses newspaper to have disjunctor playing sealing, simultaneously, plane bearing on the rubber pressing plate and plane bearing pressing plate play unresisted effect, guarantor's tower spring on the plane bearing pressing plate plays tension, the sphere of spherical connecting bar axle has disjunctor O type circle end face with the rubber pad pressing plate and seals, the locating stud of protecting on the tower spring plays the spherical connecting bar axle, the rubber pad pressing plate, plane bearing, the plane bearing pressing plate, the integral body of protecting the tower spring links up and acts on, and plays the positioning action of fan-shaped positioning plate 90 degree simultaneously.So it is big more to work as pressure, sealability is just good more, can not leak more.Leakage phenomenon can not take place in the wearing and tearing that the sphere abrasion of spherical connecting bar axle and rubber pressing plate have disjunctor O type circle yet, owing to passing forward under the effect of guarantor's tower spring.Tool total design assembling advantages of simple in addition, long service life, characteristics such as cost is low.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention
Among the figure 1 is the spherical connecting bar axle, the 2nd, and the rubber pad pressing plate, the 3rd, plane bearing, the 4th, the plane bearing pressing plate, the 5th, protect the tower spring, the 6th, locating stud, the 7th, fan-shaped positioning plate, the 8th, valve body,
Embodiment
Contrast accompanying drawing 1, its structure are spherical connecting bar axle 1 through holes by rubber pad pressing plate 2, and the end face that has disjunctor O shape circle on the sphere that makes spherical connecting bar axle 1 and the rubber pad pressing plate 2 is close to and is linked to each other, and plays sealing.Plane bearing 3 is close to the top of rubber pad pressing plate 2 by spherical connecting bar axle 1, plane bearing pressing plate 2 is arranged on the plane bearing 3 by spherical rod shaft 1, play lossless friction, guarantor's tower spring 5 is pressed on the plane bearing pressing plate 4 by the axle of spherical connecting bar axle 1, the horizontal bolt of locating stud 6 (earlier guarantor's tower spring compression) is on the axle of the spherical connecting bar axle 1 that has cross-drilled hole, the sphere that plays spherical connecting bar axle 1 is with the friction of the circle of the disjunctor O shape on the rubber pad pressing plate 2, even the ageing of rubber of rubber pad pressing plate 2, and the wearing and tearing of spherical connecting bar axle 1 sphere, still can keep not leaking, can keep overall structure.Fan-shaped positioning plate 7 endoporus are placed on locating stud 6 centres by the axle of spherical connecting bar axle 1, can make locating stud play 90 degree position-limiting actions during rotation with fan-shaped positioning plate, fan-shaped positioning plate 7 and rubber pad pressing plate 2 are fixed on the valve body 8, when pressure big more, sealability is just good more, good seal performance can not leaked more, when spherical connecting bar axle 1 rotates because the effect of plane bearing 3, resistance is quite little, even rotate spherical pitman shaft 1 for a long time, the sphere abrasion of spherical connecting bar axle 1 and rubber pad pressing plate have the wearing and tearing of disjunctor O shape circle, also leakage phenomenon can not take place, and this is owing to pass forward under the effect of protecting tower spring 5.Tool total design assembling advantages of simple in addition, long service life, characteristics such as cost is low.
Spherical connecting bar axle 1 bottom is convex shape, the ball that can connect various ball valves, it with the axle sphere that the spherical connecting bar axle 1 bottom first half at center is half garden shape, this sphere links to each other, is close to the end face that rubber pad pressing plate 2 has O shape circle, can play sealing and unresisted rotation, pressure is big more simultaneously, and sealability is good more.One horizontal small through hole is arranged at the sphere top of spherical connecting bar axle 1, this through hole, be mainly the disjunctor of sphere, rubber pad pressing plate 2, plane bearing 3, plane bearing pressing plate 4 and guarantor's tower spring 5 of spherical connecting bar axle 1, the superincumbent locating stud 6 of horizontal bolt and play coherent seal action, play the positioning action of 90 degree simultaneously with fan-shaped positioning plate 7, the top of spherical connecting bar axle 1 is concave shape, and the top of spherical connecting bar axle 1 can connect other rotatable parts.
