Summary of the invention
Main purpose of the present invention is to provide a kind of antileakaging linked two-step ball heat resistant and wear resistant and damages ball valve.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of linked two-step ball heat resistant and wear resistant damages ball valve, comprise valve body, valve seat, butterfly spring, spheroid, valve rod, valve gap, valve body comprises left valve barrel, middle valve body, right valve barrel, it is characterized in that: described middle valve body is provided with two cavitys, two cavity middle parts connect and respectively establish a spheroid, and each spheroid arranges a valve rod; Oil through on two spheroids be arranged in parallel, and two valve rods are formed and are in transmission connection by synchronous drive mechanism; The operating mechanism that one of them end setting operation spheroid of two valve rods rotates.This structure, two spheroids synchronously rotate, and open or cut-off valve passage simultaneously.In the time of seal failure in a cavity, another cavity still can ensure sealing, has high Security, and the pipeline or the environment that are particularly useful for dangerous toxic liquid gas use.
As preferably, in two cavitys in middle valve body, a valve seat is respectively set, the opposing setting of two valve seats, and between the spheroid of place cavity, butterfly spring is set.Between two cavitys, annular wall is set, annular wall middle part arranges oil through, the concentric setting of oil through on oil through and right valve barrel, left valve barrel.This structure, the sealing between valve seat and spheroid is better, and fluid resistance is little.
As preferably, described operating mechanism is handle or outside driving mechanism.Be convenient to operate manually or automatically.
As preferably, described synchronous drive mechanism is chain transmission or tooth form synchronous belt transmission.Simple in structure, synchronism is good.
As the replacement scheme of such scheme, gear, formation drive mechanism that described synchronous drive mechanism is pair of meshing.Compared to aforementioned chain transmission or tooth form synchronous belt transmission, gear transmission good rigidly, is difficult for producing larger distortion because of factors such as the reduction of burn into elasticity, temperature variation.
As preferably, two gear bodies are plane Cylindrical object, and cylinder partial excircle is provided with tooth; When two gear engagements, maximum angle rotatable is 90 °; In the time of the end of two gears in engagement driving, spheroid at middle valve body in sealing or completely on state completely.This structure is simple in structure, owing to being only provided with tooth on Cylindrical Gear face portion excircle, therefore can reduce manufacture cost, especially, can utilize the end end of tooth engagement as spacing, its maximum rotated position is completely closed between spheroid and valve pocket or conduction position completely exactly.
As preferably, two gears sidewall is outwardly provided with angle index line.Can, according to different flow needs, turn to suitable scale, facilitate the size of adjust flux.
Therefore, cavity leakage of the present invention, another cavity still can seal, have be difficult for leaking, the beneficial effect such as Safety performance is good, long service life.
