Abstract

The utility model relates to a blowing device is used in sensitive explosive production, specifically is a special relief valve of sensitive explosive production. The problem of use the tradition to revolve in the production of sensitive explosive to twist, because more seriously there is the technique of potential safety hazard in the machinery friction during screw rod type valve is solved. A special relief valve of sensitive explosive production, includes sleeve pipe and nested at the intraductal hose of cover, still include one fix on the sleeve pipe outer wall by air powered pump driven air leg, the expansion end of air leg passes the sheathed tube lateral wall and contacts with the hose, the expansion end of air leg has a baffle lieing in the outside partial fixing of sleeve pipe, is connected with the spring between the stiff end of air leg and the baffle. The utility model has the advantages of reasonable design reliably, accomplish closing and flow control of hose through the air powered pump, through the switch of the intraductal hose of the flexible completion cover of spring, reduced the machinery friction that exists when the type of twisting, the use of screw rod type valve are revolved to the tradition, have safe and reliable, simple structure, convenient just low cost's the advantage of processing.

Description

A kind of sensitive explosive production special safety valve

Technical field

The utility model relates to sensitive explosive production emptying device, is specially a kind of sensitive explosive production special safety valve.

Background technique

Because the mechanical sensitivity of sensitive explosive is higher, it should reduce the mechanical friction of equipment as far as possible when producing, but usually the blowing valve that uses in bottom is for traditional to screw, screw type, there is stronger mechanical friction, there is potential safety hazard, therefore need in a kind of using process, to produce the less valve of mechanical friction, ensure the production safety of sensitive explosive.

Summary of the invention

The utility model be use in the production solving sensitive explosive that tradition screws, screw type valve time more seriously there is the technical problem of potential safety hazard due to mechanical friction, a kind of sensitive explosive production special safety valve is provided.

The utility model adopts following technological scheme to realize: a kind of sensitive explosive production special safety valve, comprises sleeve pipe and be nested in the flexible pipe in sleeve pipe; Also comprise an air-leg driven by pneumatic pump be fixed on sleeve outer wall, the movable end of air-leg contacts with flexible pipe through the sidewall of sleeve pipe and realizes the opening and closing of flexible pipe; The partial fixing that movable end is being positioned at jacket exterior of air-leg has baffle plate, is connected with spring between the fixed end of air-leg and baffle plate.

When needing in production to reduce the sensitive explosive flow passed through in flexible pipe, start the degree that pneumatic pump controls air-leg squeezing tube, complete the control to flow in flexible pipe, spring is then stretched; After control terminates, be connected to the spring contraction between baffle plate and air-leg fixed end, regained by movable end, the flow of flexible pipe gets back to normal level.Baffle plate is used for linking springs, prevents movable end activity excessive simultaneously.

The utility model reasonable in design is reliable, closedown and the flow control of flexible pipe is completed by pneumatic pump, the switch of sleeve pipe inner flexible tube is completed by telescopic spring, the mechanical friction existed when decreasing traditional rotary-screw-type, the use of screw type valve, the requirement to equipment when sensitive explosive is produced can be met, there is advantage safe and reliable, that structure is simple, easy to process and with low cost.

1-sleeve pipe, 2-flexible pipe, 3-air-leg, 4-pneumatic pump, 5-baffle plate, 6-spring, 7-pressing plate, 8-end cap.

Embodiment

A kind of sensitive explosive production special safety valve, comprises sleeve pipe 1 and is nested in the flexible pipe 2 in sleeve pipe 1; Also comprise an air-leg 3 driven by pneumatic pump 4 be fixed on sleeve pipe 1 outer wall, the movable end of air-leg 3 contacts with flexible pipe 2 through the sidewall of sleeve pipe 1 and realizes the opening and closing of flexible pipe 2; The partial fixing that movable end is being positioned at sleeve pipe 1 outside of air-leg 3 has baffle plate 5, is connected with spring 6 between the fixed end of air-leg 3 and baffle plate 5.In Fig. 1, flexible pipe is extruded, and explosive circulation is interrupted.

The movable end of described air-leg 3 be connected with a semicircular in shape in the one end being positioned at sleeve pipe 1 inside and with the pressing plate 7 of flexible pipe 2 axes normal, semicircular pressing plate 7 is suitable with the bore of flexible pipe 2; Pressing plate 7 is contacted with flexible pipe 2 by its cambered surface.As shown in Figure 2, semicircular pressing plate 7 really can realize the keying to flexible pipe, can also guarantee that flexible pipe is not punctured simultaneously, drop to minimum to the damage of flexible pipe.

Described sleeve pipe 1 outer wall is fixed with an end cap 8, and the center of end cap 8 has hole, and described air-leg 3 is passed by end cap 8 center hole and is fixed.
