Abstract
The utility model relates to a hydraulic brake pipeline safety valve which is mainly composed of a valve core, a valve head, a ball bearing, a guide spring, and a valve body, wherein, a star-shaped path is arranged in the valve body. The valve core is arranged in the lower side of the path. The front end of the valve core is provided with an oil passage hole and a sealing ring. The middle of the valve core is provided with a rubber cup. The rear part of the valve core is fixed by the sealing ring and a sealing bolt. The ball bearing and the guide spring are arranged in the rear end of the path in vertical direction. The rear end of the path in vertical direction is sealed by a positioning fixing bolt. The valve has the advantages of compact structure and excellent design.
Description
Though existing self-propelled vehicle has the dual line braking safety measure, because the time is long, after body is aging, cracking easily; Or reason such as road surface damaged in collision in travelling, in case cause brake-press lead to burst, vehicle just can not travel even lead to the traffic accident accident.
The purpose of this utility model is to create a kind of hydraulic braking pipeline safety valve, is used for preventing that self-propelled vehicle glancing impact pipeline from bursting the traffic accident that leads to.
Main technical schemes of the present utility model is: it mainly is made up of spool, valve head, ball, retainer spring, valve body; Have one in the valve body
The shape passage is provided with spool in the following wing passage, and the spool front end has oil hole and seal ring, and there is leather cup at the middle part, and the rear end is equipped with ball and retainer spring with seal ring and sealing bolt fixed spool in the vertical oil duct in rear end, seals with the positioning and fixing bolt.
The utility model has the advantages that it can prevent that trac., three-wheel vehicle, farm vehicle, hydraulic vehicle braking pipeline from bursting the accident of causing a traffic accident at glancing impact, it is non-leakage that this safety valve can pin braking liquid automatically.Four-wheeled vehicle is installed in and replaces the threeway section header on the forward and backward bridge of vehicle, and four wheels has the brake piping of a wheel to burst, and its excess-three wheel all has brake equipment, still can continue to move; Three-wheel, cart are installed in the back axle threeway, and the brake piping of a fried wheel also has a wheel that brake equipment is arranged, and can guarantee safety.This valve can also be used hydraulic machinery, lathe, coal gas, tap water, oil, chemical industry aspect and do self locking safety valve.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Accompanying drawing is a hydraulic braking pipeline safety valve structural representation;
As shown in drawings, this valve mainly is made up of spool 1, valve head 2, ball 3, retainer spring 4, positioning and fixing bolt 5, valve body 6, section header pad 7, tube coupling head 8, seal ring 9, sealing bolt 10, seal ring 11, leather cup 12, seal ring 13, oil duct 14, valve tail 15, oil hole 16; Have one in the valve body 6
Shape passage 14, down be provided with spool 1 in the wing passage, spool 1 front end has oil hole 16 and seal ring 13, there is leather cup 12 at the middle part, ball 3 and retainer spring 4 are equipped with seal ring 11 and sealing bolt 10 standing valve tails 15 in the rear end in the vertical oil duct in rear end, seal with positioning and fixing bolt 5.The channel outlet of valve body 16 is equipped with section header pad 7 and tube coupling head 8.
The principle of work of this valve is: braking liquid flows in the valve head pipe 17 from brake piping, goes out via the upper channel of the oil hole 16 of spool front end, oil duct 14, the orifice flow of being responsible for section header 8, forms main feed flow road this moment.When operation pressure rises, braking liquid flows to the space of spool 1 by main feed flow road part through the space of retainer spring 4, because of leather cup 12 stops up, braking liquid can not flow to the spool front end and go, this moment, the pressure on both sides reached dynamical equilibrium, and the oil hole 16 of spool just coincide with oil duct 14 holes, can not misplace.When brake piping bursts, main feed flow road pressure decay, the resistance of spool also descends simultaneously, the long-pending tangent plane with oil outlet of the tangent plane of spool 1 front end accumulates in an area difference, and fwd pressure is big, and braking liquid continues stream and comes, having promoted spool 1 retreats, the oil hole 16 of spool front end because of move behind the spool with valve body on oil duct 14 holes stagger, block flowing of braking liquid, reach the purpose of self-locking in danger.After the tube coupling head 8 later pipelines that split are repaired, manually spool is pushed away reset (at this moment spool oil hole 16 is corresponding with oil duct 14 holes) forward, make its normal operation.
Existing farm vehicle, three-wheel vehicle, trac. all do not have safety device, and automobile has dual circuit but do not have the safety measure of four pipelines braking, self-locking when adopting this valve can be to each drg in danger.This valve arrangement compactness, design is exquisite.
