Abstract
The utility model relates to a break away coupling valve. The break away coupling valve comprises valve bodies, valve seats and valve clacks, wherein the valve bodies are composed of the left valve body and the right valve body, the valve seats are arranged in a channel of the left valve body and a channel of the right valve body respectively, the valve clacks are composed of the left valve clack and the right valve clack, one end of the left valve clack and one end of the right valve clack are respectively fixedly connected with an ejector rod, a left spring is installed between a left spring seat and a left end cover, and a right spring is installed between the right spring seat and a right end cover. The break away coupling valve is characterized in that a plurality of radial conical holes are evenly formed in corresponding positions of the left valve body and the right valve body in the circumferential direction, a steel ball is placed in each conical hole, and an outer cover is installed outside the steel balls and located on the outer surface of the right valve body. When snapping force is exerted, the steel balls roll out of the conical holes along the conical surfaces to enable the left valve body to be separated from the right valve body, the left valve clack is in sealing fit with the valve seat of the left valve body, the right valve clack is in sealing fit with the valve seat of the right valve body, and thus medium leakage is prevented. The break away coupling valve has the advantages of being easy to restore and install, convenient to use and the like. The break away coupling valve is suitable for being installed on an oil outlet pipeline of an oiling machine.
Description
Technical field
The utility model relates to valve field, particularly about a kind of Pull breaking ualve.The utility model is applicable to the Pull breaking ualve on transport pipe between gas station's oilling machine and nozzle.
Background technique
Between the oilling machine of gas station and nozzle, be connected by rubber pipe, nozzle is inserted in tank filler vehicle is refueled.In the time refueling, if vehicle is moved, will pull nozzle and oilling machine, and oilling machine is drawn and turned over, there is security incident, thus when preventing from refueling the vehicle accidental movement accident that meets accident, general employing installed Pull breaking ualve between oilling machine and nozzle.Existing Pull breaking ualve is generally made up of left and right valve body, left and right flap, left and right valve seat, under normal state, left and right flap and left and right valve seat are in disengaged position, and when refueling process generation vehicle accidental movement, Pull breaking ualve is pulled off, the flap of the left and right sides and valve seat are closed respectively, prevent that oil from leaking.But after the left and right valve body of existing Pull breaking ualve is broken, recovery connects more difficult, use inconvenient.
Summary of the invention
The purpose of this utility model is the shortcoming existing for prior art, provides a kind of and breaks that rear easy recovery connects, Pull breaking ualve easy to use.
The technical solution of the utility model comprises valve body, valve seat, flap; Valve body is made up of left valve barrel and right valve barrel, is shaped with respectively valve seat in the passage of left valve barrel and right valve barrel, and flap is made up of left flap and right flap, and one end of left flap and right flap is fixedly connected with respectively a push rod; The other end of left flap is fixedly connected with left spring seat, the other end of right flap is fixedly connected with right spring seat, between left spring seat and left end cap, left spring is installed, right spring is installed between right spring seat and right end cap, left end cap is installed on left valve barrel by screw thread, and right end cap is installed on right valve barrel by screw thread; Under left valve barrel and right valve barrel coupled condition, the push rod of left flap and right flap contacts mutually, and the valve seat in the valve seat in left flap and left valve barrel and right flap and right valve barrel is all in disengaged position; Be mainly along the circumferential direction evenly to manufacture several conical bores radially at left valve barrel and right valve barrel corresponding position, in each conical bore, place respectively a steel ball, at the right valve barrel outer surface in steel ball outside, outer cover is installed.
The utility model has the advantages that left valve barrel and right valve barrel adopt the interior steel ball of installing of conical bore to be connected, utilize steel ball to embed between left valve barrel and the conical bore of right valve barrel, left valve barrel and right valve barrel are interconnected, in the time there is pull-off force, steel ball rolls out along the conical surface in conical bore, left valve barrel is separated with right valve barrel, and left flap coordinates with the valve base sealing of right valve barrel with valve seat and the right flap of left valve barrel, prevents that medium from leaking.Recover Pull breaking ualve and only need, by left valve barrel and the alignment of right valve barrel conical bore, pack steel ball, outer cover into, it recovers to install easy, easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
