Abstract
The utility model discloses an oxygen stop valve which comprises an executing mechanism, a valve body, a valve deck, a support, a valve rod and a main valve clack, wherein the valve body is connected with the valve deck, the valve deck is connected with the support, one end of the valve rod is connected with the executing mechanism, and the other end of the valve rod is connected with the main valve clack; gas channels are arranged in the valve body, an inlet channel is arranged on one side and an outlet channel is arranged on the other side, and the main valve clack is arranged between the inlet channel and the outlet channel when the stop valve is closed; a through hole is formed between the inlet channel and the outlet channel, a guiding rod is arranged at one end of the main valve clack, and the guiding rod penetrates through the through hole. According to the oxygen stop valve, due to the fact that the guiding rod is arranged below the valve clack and can move up and down in the formed through hole, swinging of the valve clack and the valve rod under pressure is avoided, and the valve is stabilized. Furthermore, the valve clack of the stop valve can also be provided with one or more air channels used for connecting the front side of the valve with the back side of the valve, then the pressure difference between the front side of the valve and the back side of the valve can be reduced, and the valve can be opened and closed fast.
Description
Technical field
The utility model belongs to mechanical device technical field, relates to a kind of stop valve, relates in particular to a kind of oxygen stop valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Existing oxygen stop valve is only provided with a flap conventionally, there is no balance, pooling feature, and pressure reduction is after and before the valve too large, inconvenient fast opening/closing valve.Meanwhile, the easy pressurized of existing stop valve clack rocks, and element easily damages.In addition, existing oxygen stop valve complex structure, cost is higher.
In view of this, nowadays in the urgent need to designing a kind of new oxygen stop valve, to overcome the defect of existing stop valve.
Model utility content
Technical problem to be solved in the utility model is: a kind of oxygen stop valve is provided, can avoids flap, valve rod pressurized to rock, play the effect of firm valve.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
, described stop valve comprises: actuator, valve body, valve gap, support, valve rod, main valve clack;
Described valve body is connected with valve gap, and valve gap is connected with support; One end of described valve rod connects actuator, and the other end connects main valve clack;
In described valve body, be provided with gas channel, a side is inlet channel, and opposite side is outlet passage, and when stop valve is closed, main valve clack is arranged between inlet channel and outlet passage;
Between described inlet channel and outlet passage, be provided with a through hole, one end of described main valve clack is provided with guide rod, and guide rod is through this through hole.
As a kind of preferred version of the present utility model, described actuator comprises handwheel.
As a kind of preferred version of the present utility model, described valve body, valve gap, support form cut-off valve housing, and valve rod is arranged in housing; Valve rod and valve gap contacting point are provided with one or more O type circles.
As a kind of preferred version of the present utility model, the medial axis of described guide rod and the medial axis of valve rod are point-blank.
The beneficial effects of the utility model are: the oxygen stop valve the utility model proposes, and by guide rod is set below flap, make guide rod up and down in the through hole of setting, can avoid flap, valve rod pressurized to rock, play the effect of firm valve.In addition, the flap of the utility model stop valve can also arrange one or more connections gas flow after and before the valve, can reduce pressure reduction after and before the valve, fast opening/closing valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model oxygen stop valve.
