Abstract
The utility model relates to an automatic closing safety valve for the flow quantity of oil, gas and water, which is arranged and connected to the pipe lines of oil, gas and water pipelines and can be automatically closed when the oil, the gas and the water are leaked. The valve comprises a valve head, a valve body and a valve core. The valve head and the valve body are arranged on a same shaft line, and the interior of the valve body is provided with a spherical valve core. One side of the valve core is a blocking spring, and the other side is a pressure spring. When a liquid outlet pipeline generates the leakage, the valve core is immediately forward moved to tightly contacted with the valve base position of the valve body because the pressure of an output end is quickly reduced, and thus the purpose of stopping the flow is obtained.
Description
The utility model relates to a kind of being installed on oil, gas, the waterpipe pipeline, particularly when oil, gas, water take place to reveal, and the safety valve that can close automatically.
In pipeline pipeline collection is defeated, just monitor at present and leakage-preventing in advance by supporting facility such as safety valve, pressure gauges.In case liquid, gas leakage take place, can't solve automatic closing problem, can only carry out leak stopping with conventional way, economy is suffered a loss even make casualties.
The purpose of this utility model is to provide a kind of when the pipeline pipeline take place to be revealed, the safety valve that can in time close automatically, and it is the leakage of control gaseous or liquid at once.
The purpose of this utility model is achieved in that oil, gas, the automatic closed safe valve of water flow
Comprise valve head, valve body and spool, valve head and valve body coaxial line are installed, its technological points is on the inner cylindrical surface of sleeve shape valve head two steps to be arranged, and the valve body front end withstands on the minor diameter step of valve head, and the external cylindrical surface of valve body is processed a boss, this boss withstands on the major diameter step of valve head, one spool that can move horizontally is installed in the valve body, and spool is fixed on the catch spring, and 5 high points are arranged on the catch spring, in 5 horizontal slots of valve body, the spool opposite side is a pressure spring respectively for 5 high points.
Adopt the utility model oil, gas, the automatic closed safe valve of water flow, when liquid, when the gas proper set is defeated, these valve both sides are in relative equilibrium, and this moment, valve was in opening state.When the outlet side of this valve takes place to reveal, because this side pressure reduces at once, cause the valve both sides bigger pressure difference to occur, big at inferior input side pressure, under the little interaction of outlet side pressure, this valve returns and is in closed condition at once automatically.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a sectional view of the present utility model.
1. valve heads, 2. valve bodies, 3. spools, 4. pressure springs, 5. valve seat positions, 6. seal rings, 7. catch springs, 8. horizontal slots among the figure
As shown in drawings, oil, gas, the automatic closed safe valve of water flow comprise valve head (1), valve body (2) and spool (3), and valve head (1) is installed with valve body (2) coaxial line, is embedded with seal ring (6) between valve head (1) afterbody and the valve body (2).Valve head (1) is a sleeve shape, and two steps of large and small diameter are arranged on the inner cylindrical surface of valve head, and valve body (2) front end withstands on the minor diameter step of valve head (1), and the external cylindrical surface of valve body (2) is processed a boss, and this boss withstands on the major diameter step of valve head (1).One spool that can move horizontally (3) is installed in the valve body (2), and spool (3) is spherical, and spool (3) is fixed on the catch spring (7).Valve body (2) inwall 5 horizontal slots (8) that evenly distribute have 5 high points on the catch spring (7), 5 high points are respectively in 5 horizontal slots (8) of valve body (2).Horizontal slot (8) plays the effect that fixing catch spring (7) prevents its rotation.Be pressure spring (4) between spool (3) and the valve head (1).
After liquid, gas entered valve from inlet opening A end, spool (3) was in relative balance state under the interaction of spring (4) and hydrodynamic pressure, made fluid smoothly by this valve.When liquid, gas take place to reveal at delivery outlet B end pipeline, owing to the B end pressure reduces rapidly, under hydrodynamic pressure, this valve pressure at both sides difference is bigger, impels spool (3) to move forward at once, locates tight the contact with valve body (2) valve seat position (5), this moment, valve was in closed condition, reached the cutout purpose.
Claims (3)
1. oil, gas, the automatic closed safe valve of water flow, comprise valve head (1), valve body (2) and spool (3), valve head (1) is installed with valve body (2) coaxial line, it is characterized in that on the inner cylindrical surface of sleeve shape valve head (1) two steps being arranged, valve body (2) front end withstands on the minor diameter step of valve head (1), the external cylindrical surface of valve body (2) is processed a boss, this boss withstands on the major diameter step of valve head (1), one spool that can move horizontally (3) is installed in the valve body (2), spool (3) is fixed on the catch spring (7), 5 high points are arranged on the catch spring (7), and in 5 horizontal slots (8) of valve body (2), spool (3) opposite side is pressure spring (4) respectively for 5 high points.
2. automatic closed safe valve according to claim 1 is characterized in that being embedded with seal ring (6) between valve head (1) afterbody and the valve body (2).
3. automatic closed safe valve according to claim 1 is characterized in that spool (3) is for spherical.
