Progress along with engine technology, engine power density improves gradually, the research of heat transfer technology becomes key technology to be solved, for dwindling the temperature heat transfer gradient between engine component, the motor return water temperature improves gradually, cooling system needs more and more higher system pressure, does not at high temperature vaporize to guarantee circulating water.The present invention can meet motor closed cooling system pressure and regulate needs, makes at high temperature vaporization not of cycle of engine cooling water, engine component efficiently radiates heat, the damage of having avoided the cooling water high-temperature evaporation to bring to motor.
Summary of the invention
The present invention is directed to motor enclosed cooling recirculation system, designed the two-way aeration regulation valve of a kind of self-powering type, both can meet system pressure 100～300kPa (relative pressure) pressurize regulates, can meet again negative pressure-5～0 kPa auto-admission requirement in system, avoid the adverse effect of bringing to motor due to systemic circulation water high-temperature evaporation and system negative pressure, thereby make the engine high-temperature cool cycles become possibility, both ensured the efficiently radiates heat of motor parts and components, made again the convenient adjustment of system works pressure.
Technological scheme of the present invention: the two-way aeration regulation valve of a kind of self-powering type, it comprises valve body 1 and the inner pressure regulation system arranged of valve body 1, valve body 1 lower outside is provided with external screw joint, upper inner is provided with internal thread interface, it is characterized in that pressure regulation system comprises exhaust pressure-retaining system and air inlet pressure-retaining system;
Described exhaust pressure-retaining system is by thrust snap ring 2, lower end cap 3, rubber pad 4, big valve core body 5, exhaust spring 6, upper end cap 7 and pressure regulation body 8 form, the lower end cap 3 of center drilling is fixed in 1 time cavity of valve body by the thrust snap ring 2 be nested in valve body 1, the big valve core body 5 that has through hole is arranged on valve body 1 upper plenum bottom, wherein rubber pad 4 is inlayed to be installed on below big valve core body 5 and with the sealing plane of valve body 1 and is fitted, pressure regulation body 8 is connected by internal thread interface with valve body 1 upper plenum port, below pressure regulation body 8, be provided with upper end cap 7, wherein between big valve core body 5 and upper end cap 7, be provided with exhaust spring 6,
Described air inlet pressure-retaining system is comprised of air inlet spring 9, pressure pad 10, look nut 11 and small valve core body 12, small valve core body 12 is arranged in the through hole of big valve core body 5, its upper end and look nut 11 are threaded connection, below look nut 11, be set to pressure pad 10, between pressure pad 10 and big valve core body 5, be provided with air inlet spring 9, wherein small valve core body 12 bottoms are connected with described rubber pad 4 sealing contacts;
Described small valve core body 12 structures are that lower end is disk-like structure, and the disk-like structure center is provided with screw rod.
Described exhaust spring 6 and air inlet spring 9 elongation springs.
Described upper end cap 7 middle parts are offered porose.
Beneficial effect of the present invention: the present invention is applicable to all motor enclosed cooling recirculation systems fluid closed circulation system similar with other, can change quickly and easily internal system pressure, reaches the pressure regulation purpose.And the two-way aeration regulation valve body of this self-powering type is long-pending little, lightweight, cheap, and thread type screws installation, and easy accessibility is convenient to upgrading and the maintenance of engine testing room or vehicle-mounted cooling system.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the two-way aeration regulation valve body of this self-powering type 1 outside has external screw joint, inboard has internal thread interface, and the outer threaded coupling of valve body 1 is installed on the swelling water tank of motor closed system, and internal thread interface is used for fixing spool and realizes the adjusting of exhaust spring 6 decrements.The inner threaded coupling of spool of the two-way aeration regulation valve of self-powering type and the location of the screw-thread fit on pressure regulation body 8, order about moving up and down of upper end cap 7 by forward and reverse rotation pressure regulation body 8, thereby change the decrement of exhaust spring 6.The variation of exhaust spring 6 decrements, changed it and be applied to the active force on big valve core body 5, and the active force that same big valve core body 5 is applied to rubber pad 4 also changes thereupon, makes the sealing force size variation at rubber pad 4 and valve body 1 faying surface place.Valve body 1 bottom is equipped with lower end cap 3, and it is fixed together by thrust snap ring 2 and valve body 1, and lower end cap 3 has through hole, guarantees that this modulating valve can sense the variation of swelling water tank internal pressure in time.That is, by the upper and lower rotation of pressure regulation body 8, just can change the exhaust cracking pressure, just can realize the adjusting of closed circulation system internal pressure.Air inlet spring 9, for the elongation spring, is between pressure pad 10 and small valve core body 12, and air inlet spring 9 is exerted a force in pressure pad 10 and small valve core body 12, and pressure pad 10 is blocked by look nut 11, and its active force orders about the small valve core body and abuts against on rubber pad 4, plays seal action.By the upper and lower turn of look nut 11, just can change the elongation of air inlet spring 9, thereby change the size of small valve core body 12 and rubber pad 4 sealing forces, realize the purpose of air inlet pressure regulation.Pressure regulation body 8 and upper end cap 7 have through hole, and when the closed system internal pressure changed, the system external world can sense the variation of pressure at any time, carried out in time the tonifying Qi pressure regulation.
