Abstract
A multi-function cylinder stop valve is characterized in that: A. a handle wrench 5 is sleeved and arranged at the upper end of a nut 1; B. a valve body 8 which is arranged at the lower end of the nut 1 is a three-way structure, a lower through hole of the valve body 8 is provided with an automatic valve core 9 and is located by a bolt 11, while a return spring 10 is sleeved and arranged on the automatic valve core 9 which is positioned on the same axis with a manual stop valve core 6. The utility model has the switch function as well as the function of propping up the automatic valve to guide a gas channel, which can automatically cut a valve gas passage in emergency and avoid the dangerous accidents, such as fire, explosion and so on caused by the gas leakage. The stop valve is simple in structure, practical and easy to be produced in bulks.
Description
One, technical field:
The utility model relates to a kind of stop valve, compressed natural gas especially, the multi-functional gas cylinder stop valve of bottled gas such as oxygen.
Two, background technique:
At present, in the industry of gases such as bottled compressed natural gas, using maximum is compressed natural gas used as vehicle fuel cylinder valve and oxygen cylinder valve, and they all are stop valve or ball valve.These valves are two logical or three-port structures, it opens or closes the air valve passage by handwheel or handle spanner, when the safe spool of this air valve surpassed safety relief pressure in the gas cylinder internal pressure, the energy releasing pressure automatically guaranteed gas cylinder safely, but when in a single day the pipeline that connects gas cylinder takes place to leak, because this cylinder valve does not have the passage of dying automatically,, can not in time control leakage therefore for being filled with inflammable gas or gas cylinder poisonous, harmful gas, the fire that causes thereby Yi Fashengyin leaks, danger such as blast.
Three, summary of the invention:
The purpose of this utility model provides a kind of multi-functional gas cylinder stop valve, by changing the internal structure of original cylinder valve, solution is equipped with inflammable, the poisonous unexpected gas leakage problem that takes place of gas cylinder pipeline that waits gas, thereby avoid the fire that causes because of gas leakage, perils such as blast.
The concrete scheme of the purpose of this utility model is: comprise nut,, screw, valve rod, seal ring, hand stop valve core, sealing valve pad, valve body, valve port, safety valve is characterized in that: A. nut upper end is set with the handle spanner; B. the valve body that is installed in the nut lower end is a three-port structure, and automatic spool is installed in its lower through-hole, by the bolt location, is being set with return spring on the spool automatically, and spool and hand stop valve core are positioned on the same axis automatically.
Adopt such scheme to have switching function and back down self-acting valve, the function of conducting gas circuit can automatic emergency cutting-off valve air flue, can avoid the fire that causes because of gas leakage, perils such as blast.It is simple in structure, and practicality is produced in batches easily.
Four, description of drawings:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Five, embodiment:
Please see Figure 1, Fig. 2, the utility model mainly is made up of nut 1, screw 2, valve rod 3, seal ring 4, handle spanner 5, hand stop valve core 6, sealing valve pad 7, valve body 8, automatic spool 9, return spring 10, bolt 11, safety valve 13 etc., wherein valve body 8 tops are threaded with nut 1, nut 1 interior being equipped with between valve rod 3, valve rod 3 and the nut 1 through screw 2 has seal ring 4, valve rod 3 belows are stretched in the hand stop valve core 6, hand stop valve core 6 is threaded in the valve body 8, and is positioned at valve body 8 triple channel top.Structure outline of the present utility model is: A. nut 1 upper end is set with handle spanner 5; B. the valve body 8 that is installed in nut 1 lower end is three-port structures, and automatic spool 9 is installed in its lower through-hole, by bolt 11 location, is being set with return spring 10 on the spool 9 automatically, and spool 9 is positioned on the same axis with hand stop valve core 6 automatically.
As can be seen from Figure 1: automatically spool 9 centers are porose 14, and it is step-like that profile is.The handle spanner 5 that is sleeved on the nut 1 is connected with valve rod 3 by screw 2.
Working principle of the present utility model is: the stop valve suction port is connected on the gas cylinder air outlet, open gas cylinder valve, stop valve upper handle spanner 5 is in full-gear, gas enters in the stop valve in the gas cylinder, when stop valve is worked under normal flow rate, automatically spool 9 is in full-gear, when pipe breakage that connects gas cylinder or gas leakage, pressure difference in stop valve outlet end pressure and the gas cylinder surpasses design load, the output flow that is stop valve surpasses design load, and at this moment spool 9 is at action of pressure lower compression return spring 10 automatically, and the small end head of spool 9 stretches into valve port 12 automatically, self acting stop valve mouth 12, stop valve quits work.After treating that hidden danger is eliminated, handle spanner 5 is in half-open position, at this moment hand stop valve core 6 backs down automatic spool 9, makes stop valve be in normal opening state, and when handle spanner 5 was in fully open position, hand stop valve advanced shutoff, the exhaust passage.
