Abstract
A pull breaking valve for preventing the medium delivering pipeline from being broken off is composed of primary valve, secondary valve, safety unit, and fixing unit. The tops of valve rods of primary and secondary valves are in contact with each other. Said safety unit consists of spring and internal plastic sleeve. The spring is between the peripheral shoulder of primary valve and internal plastic sleeve with the jaws at its one end. Said jaw has the inward inclined shoulder to match with the outward inclined shoulder of secondary valve. After the both valves are separated from each other, the internal plastic sleeve can be restored to its original state under the action of spring and its elasticity, so the produt can be connected again for normal use.
Description
Technical field
The present invention relates to a kind of pipeline medium control setup, specifically about a kind of Pull breaking ualve that prevents the medium pipeline fracture.The present invention is applicable to and is installed on the fuel charger oil pipeline.
Background technology
Pull breaking ualve is mounted in a kind of safety guard on the fuel charger oil pipeline, is made up of main valve, secondary valve, bindiny mechanism's three parts, and main valve and secondary valve are made up of valve body, valve seat, flap, spool respectively, and main valve body and auxiliary valve body are fixed by connecting pin.Pull breaking ualve is installed between fuel charger and the nozzle, in normal operation, main valve body and auxiliary valve body are linked together by connecting pin, and its main valve plug and auxiliary valve core contact mutually, the valve seat that main valve clack and secondary flap are cooperatively interacted with it respectively is separated, and medium can pass through from Pull breaking ualve.When the pipeline that connects Pull breaking ualve or nozzle are subjected to pulling force and surpass setting value, connecting pin on the Pull breaking ualve can be broken, main valve body is separated with auxiliary valve body, main valve clack and secondary flap cooperate with corresponding valve base sealing under action of the spring respectively, prevent in the pipeline that oily medium is from the past external leakage of fracture and the safety misadventure that meets accident.Yet the connecting pin of existing product is subjected to pulling force that strict demand is arranged to it, pass through strict calculating processing, can not arbitrarily adopt, so after connecting pin was broken, Pull breaking ualve can not recover to use, and can only discard, and causes the very big economic loss and the wasting of resources.
Summary of the invention
The shortcoming that can not recover to use after the objective of the invention is to break at existing product provides the Pull breaking ualve that can recover to use after a kind of the breaking.
The technical scheme that realizes the object of the invention comprises main valve, secondary valve, safety device, anchor fitting, main valve stem and auxiliary valve rod contact mutually, its key problem in technology is that safety device is made up of cover in spring and the plastics, spring is installed between the shoulder and the interior cover of plastics of main valve body periphery, an end of cover is shaped on claw in the plastics, inclined-plane convex shoulder in each claw end is shaped on; The auxiliary valve body peripheral end is shaped on outer inclined-plane convex shoulder, cooperates with the interior inclined-plane convex shoulder setting-in of cover claw in the plastics, is located by anchor fitting between the two.
In above technical scheme, anchor fitting is made up of nest and retainer spring, nest one end be shaped on plastics in the draw-in groove that cooperatively interacts of cover claw, axially be movably installed in the auxiliary valve body periphery, the convex shoulder aligned in position of its draw-in groove position and auxiliary valve body end, the other end of nest connects retainer spring.
In technique scheme, the spring of safety device is the ripple laminated structure.
The advantage that the present invention compares with existing product is to adopt between main valve body and the auxiliary valve body safety device that cover is formed in spring and the plastics to be connected, after pulling out in the interior inclined-plane convex shoulder of external force with auxiliary valve body cover claw in the plastics, main valve body separates with auxiliary valve body, be enclosed within the plastics under self elasticity and the action of the spring and restore to the original state, make product plug-in mounting recovery use again, avoid the economic loss and the wasting of resources.

The specific embodiment
Pull breaking ualve as shown in Figure 1 is made up of main valve, secondary valve, safety device, anchor fitting and sealing member.Main valve is made up of main valve body 1, main valve clack 17, main valve stem 16 and spring 18, and the structure of secondary valve is identical with main valve.One end of main valve stem and auxiliary valve rod contacts mutually, and the other end is installed in main valve body and the auxiliary valve body by locating rack 15 respectively, and main spool spring 18 and auxiliary valve spring 11 are installed in respectively between separately the flap back side and locating rack, and locating rack is by ring washer 10 extreme position.Be respectively equipped with seal ring 14 on main valve clack and the secondary flap, be provided with seal ring 13 between main valve body 1 auxiliary valve body.Main valve and secondary valve are connected together by safety device.Safety device is made up of cover 4 in spring 3 and the plastics, and spring 3 is installed between the shoulder and the interior cover 4 of plastics of main valve body 1 periphery, and cover 4 ends that are positioned at auxiliary valve body 9 sides evenly are shaped on claw in the plastics, inclined-plane convex shoulder in each claw end is shaped on, as shown in Figure 2.Spring 3 adopts the ripple laminated structure, keeps the stability of elastic force, as shown in Figure 4.The end periphery of auxiliary valve body 9 and main valve body 1 contact position, evenly be shaped on plastics in the corresponding outer inclined-plane of the claw convex shoulder of cover 4, this outer inclined-plane convex shoulder cooperates with the interior interior inclined-plane convex shoulder setting-in that overlaps 4 claws of plastics, is located by anchor fitting between the two.Anchor fitting is made up of nest 7 and retainer spring 12, nest 7 one ends be shaped on plastics in the draw-in groove that cooperatively interacts of cover 4 claws, as shown in Figure 3.Nest 7 is installed in auxiliary valve body 9 peripheries, and with axially movable cooperation the between the auxiliary valve body 9, the back side heads on retainer spring 12, and on auxiliary valve body 9 ring washer 8 is set, and limits the position that moves axially of nest 7.The convex shoulder aligned in position of nest 7 draw-in groove positions and auxiliary valve body 9 ends, when cover 4 claws in the plastics insert from the draw-in groove between auxiliary valve body 9 adjacent two convex shoulders, and the rotate to an angle interior inclined-plane convex shoulder that makes claw and outer inclined-plane convex shoulder on the auxiliary valve body 9 align setting-in when cooperating, nest 7 draw-in grooves block the claw of cover 4 in the plastics under retainer spring 12 effects, prevent that main valve body 1 and auxiliary valve body 9 from relatively rotating.Main valve body 1, auxiliary valve body 9 are respectively equipped with shell 5,6, and ring washer 2 fixed housings 5 are set on main valve body 1.Shell 5,6 is the oil resistant plastics material, adopts the PA material in the present embodiment.Cover 4, nest 7 adopt Mitsubishi's acetal plastic in the plastics.Main valve body 1, auxiliary valve body 9 adopt the die casting of metallic zinc material to form.
