Abstract
The utility model relates to a novel unidirectional valve, which is a novel unidirectional value capable of normally working at high temperature and high pressure. The novel unidirectional valve is composed of a valve body, a valve core male, a valve core female, a spring and an O-shaped ring. The O-shaped ring is arranged in an O-shaped groove of the valve core male and the valve core female; the valve core male and the valve core female are used for fixedly fastening the O-shaped ring; the surface area of the installed O-shaped ring exposing out of the valve core is 1/3 of the O-shaped surface area. At the presence of quite high temperature and quite large pressure difference, the O-shaped ring, which is very liable to deform, is fixedly fastened in the valve core so that the O-shaped ring, which is very liable to deform, does not easily deform and release. And such a unidirectional valve greatly improves the reliable operation index of equipment.
Description
Affiliated technical field
The utility model relates to a kind of novel one-way valve, be a kind of can be under high temperature, high-pressure situations the novel one-way valve of proper functioning.
Background technique
At present, O type circle very easily was out of shape with the increase of temperature when the one-way valve on the market was used for the environment of high temperature, high pressure, cause coming off of 0 type circle at last, and still be blank out on our this novel one-way valve market, we are to be the research basis with the one-way valve, change the practical product that the one-way valve cored structure extends out with the screens method that changes O type circle.
Summary of the invention
Technical problem to be solved in the utility model is in order to overcome one-way valve O type circle yielding coming off under the environment of High Temperature High Pressure, and the problem that causes pressurized gas to be played a reversed role provides a kind of novel one-way valve in line with the principle of practicality.
Principle in line with practicality provides a kind of novel one-way valve: it is characterized in that it being by valve body, and the spool son, the spool mothers and sons, spring and O type circle are formed, O type circle and spool son and spool mother and sons' degree of adaptability threaded adjusting; The Placement that it is characterized in that spool son and spool mothers and sons is a screw thread; The inclined-plane tapering that it is characterized in that assembling good spool son and spool mothers and sons is at same horizontal plane; The degree of depth that it is characterized in that spool inclined-plane O type groove equals 2/3rds of O type cross section circular diameter.
This novel one-way valve not only can be under the huge situation of temperature and pressure proper functioning, and overcome one-way valve O type circle yielding coming off under the environment of High Temperature High Pressure, improved equipment reliable operation index greatly.
Description of drawings
Fig. 1 one-way valve structures schematic representation.
Fig. 2 one-way valve structures is broken view.
1 is valve body, and 2 is valve body, and 3 is the spool mothers and sons, and 4 is O type circle, and 5 is the spool son, and 6 is spring.
Embodiment
Referring to Fig. 1,2, a kind of novel one-way valve is to be made of valve body, spool son, spool mothers and sons, spring, O type circle.O type circle is installed among the O type groove with spool son and spool mothers and sons, and with spool son and the spool mothers and sons O type that fastens circle inflexibly, and it is 1/3rd of O type surface area that the surface area that good O type circle exposes spool is installed.When high temperature with greatly during pressure reduction, very easily the O type circle of distortion is by being buckled among the spool inflexibly, do not make the O type circle of very easily distortion yielding and come off.Such one-way valve has improved equipment reliable operation index greatly.
