Description
Technical field
The utility model relates to a kind of manufacturing technology field of valve, particularly a kind of formation testing when test, manufacturing technology field of the valve that setting-out is used of being used for.
Background technique
All-pass footpath setting-out valve is connected between LPR-N valve and the RD safety circulating valve usually, be used to release pressure and setting-out between two valves, mainly comprise, valve body, the setting-out plug, spool, pipe close, stop nut is formed, lay down the setting-out plug with hexagon wrench during setting-out, connect sample transfering device, unload loose stop nut then, with special tool the setting-out valve body is carried out the setting-out operation again, there is irrationality in design in this valve, place, setting-out valve body hexagonal top is short and thinner partially, wear and tear easily when dismantling with special spanner, in the using process, the setting-out valve body is if be damaged, just can't produce the high pressure sample of trap between RD safety valve and LPR-N valve, there is potential safety hazard, in addition, existing all-pass footpath setting-out valve, its complex structure, use loaded down with trivial details, processing also the difficulty.
The model utility content
Existing all-pass footpath setting-out valve is fragile in order to solve, the shortcoming of complex structure, complex operation, and the utility model provides a kind of all-pass footpath setting-out valve.
The utility model comprises valve body, upper connection is threaded in the upper end of described valve body, lower contact is threaded in the lower end of described valve body, outside described valve body, be nested with sliding sleeve, described sliding sleeve is arranged between described upper connection and the lower contact, connect swivel nut in the upper end of described sliding sleeve outside screw, described swivel nut is arranged between described upper connection and the sliding sleeve, on the valve body between described upper connection and the sliding sleeve, step surface is set, the upper end of described swivel nut is arranged between described upper connection and the described step surface, setting-out hole on described valve body, being provided with, setting-out hole outside on described sliding sleeve, being provided with.
The utility model is when setting-out, for being threaded, it is up to spur sliding sleeve by rotary threaded sleeve between swivel nut and the sliding sleeve, when inside and outside setting-out hole is communicated with, sample in the tubing string flows out setting-out from the setting-out hole, simple, the handling safety, easy to use of this all-pass footpath setting-out valve arrangement.
