Abstract
The invention relates to the technical field of high-pressure airless spraying equipment. A common high-pressure exhaust valve is sealed by a central metal ball and a soft face in a contacted mode, the tight fit sealing mode is adopted for sealing, under the action of high pressure, the metal ball and the soft sealing face are prone to being damaged by high-pressure cutting when the high-pressure exhaust valve is opened instantly, and consequently a machine cannot work normally. A high-pressure exhaust valve for a high-pressure airless sprayer is provided by the invention and is characterized in that the high-pressure exhaust valve for the high-pressure airless sprayer comprises an exhaust valve body and a hand wheel; the exhaust valve body comprises a base, an exhaust valve bush, a ceramic ball, a ceramic ball fixing rod, an exhaust valve screw, a clamp spring and sealing rings; the base, the ceramic ball, the ceramic ball fixing rod and the exhaust valve screw are arranged in the exhaust valve bush; and the base is in interference fit with an end hole of the exhaust valve bush. The sprayer high-pressure exhaust valve which is high in high-pressure bearing capacity, not liable to be blocked, long in service life and easy to machine is designed by modifying traditional air exhaust valve structures.
Description
Technical field
The present invention relates to high pressure airless spray equipment equipment technical field, be specifically related to a kind of high pressure airless spray equipment high pressure dump valve.
Background technology
High pressure airless spray equipment, utilizes high pressure dump valve by the air existing in high-pressure spraying machine or to be gathered in the highly pressurised liquid discharge within machine, makes high pressure airless spray equipment interior without inclusion of air, it is ensured that machine normal operation.Existing high pressure airless spray equipment uses traditional fast opening ball valve and uses as high pressure dump valve, and opening and closing element is made with the spheroid of manhole in ball valve Shi Yong center, and spheroid rotates the valve realizing switching motion with valve rod.The opening and closing element of ball valve is a porose spheroid, rotates around the axis being perpendicular to passage, thus reaches to open and close the purpose of passage.Ball valve is used mainly for opening and closing pipeline and equipment medium.Existing high pressure dump valve, have the disadvantage in that conventional high pressure dump valve is contacted sealing by the hard spheres at center with soft, tight fit sealing means is used to seal, under high pressure effect, if moment opens easily causes spheroid and the damage of soft seal face impacting with high pressure, machine is caused normally to work.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of high pressure airless spray equipment high pressure dump valve, by transforming conventional evacuation air valve structure, designing one, to bear high pressure ability strong, is not easily blocked, length in service life, the high pressure airless spray equipment high pressure dump valve of easily processing.
The technology of the present invention solution:
A kind of high pressure airless spray equipment high pressure dump valve, it is characterized in that: described high pressure airless spray equipment high pressure dump valve includes that dump valve valve body and handwheel, described dump valve valve body include that base, dump valve valve pocket, Ceramic Balls, Ceramic Balls fix bar, dump valve screw rod, jump ring and sealing ring.Described base, Ceramic Balls, Ceramic Balls fix bar and dump valve screw rod is arranged on inside dump valve valve pocket, base is installed with discharging valve pocket interference fit, Ceramic Balls uses mode of heating press-in Ceramic Balls to fix in bar one stomidium, Ceramic Balls is fixed bar and is contacted sealing by Ceramic Balls sphere with alloy seat arc surface, dump valve screw rod is sealed by O and dump valve valve pocket, dump valve screw rod is fixed in discharge valve pocket by jump ring, and handwheel is connected by self-locking nut, pad and dump valve screw rod.
Described base is alloy base.
Described sealing ring includes inner seal ring and exterior seal ring.
On described inner seal ring is arranged in dump valve screw flutes, exterior seal ring is arranged in dump valve valve pocket groove.
On described high pressure dump valve valve pocket, base one end is provided with external screw thread.
The method have the benefit that
Present configuration is simple, design ingenious, by conventional evacuation valve train is transformed, solve the flimsy shortcoming of conventional high-tension dump valve, designing one, to bear high pressure ability strong, high temperature resistant, be not easily blocked, length in service life, the high pressure airless spray equipment high pressure dump valve of easily processing.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is that the present invention installs combination schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described further by embodiment.
A kind of high pressure airless spray equipment high pressure dump valve, including dump valve valve body and handwheel 8, dump valve valve body includes that base 1, dump valve valve pocket 2, Ceramic Balls 3, Ceramic Balls fix bar 4, dump valve screw rod 5, jump ring 6, inner seal ring 7 and exterior seal ring 12,.Base 1, Ceramic Balls 3, Ceramic Balls fix bar 4 and dump valve screw rod 5 arranges and is arranged on dump valve valve pocket 2 inside, base 1 is installed with discharging valve pocket 2 one stomidium interference fit, it is provided with arc surface on base 1, Ceramic Balls 3 uses mode of heating press-in Ceramic Balls to fix in bar 4 one stomidium, Ceramic Balls is fixed bar 4 and is sealed with base 1 arc surface by Ceramic Balls 3 sphere, dump valve screw rod 5 is sealed by inner seal ring 7 and dump valve valve pocket 2, and dump valve screw rod 5 fixes dump valve screw rod 5 flight by jump ring 6.Handwheel 8 is connected by self-locking nut 9, pad 10 and dump valve screw rod 5, base 1 is alloy base, inner seal ring 7 is arranged in the groove of dump valve screw rod 5, and exterior seal ring 12 is arranged in the groove of dump valve valve pocket 2, and dump valve valve pocket 2 is provided with screw thread 11 near base one end.
Embodiment:
During work, rotation hand wheel 8 counterclockwise, handwheel 8 drives dump valve screw rod 5 to rotate to exits valve body 11 opposite direction, it is high pressure dump valve to open, high pressure matter is through base 1 centre bore, promoting Ceramic Balls 3 and Ceramic Balls to fix bar 4, pushing away base 1, air or other material can discharge outside machine body at dump valve valve body 11 side opening 13.Turn clockwise after air or other material emptying handwheel 8, dump valve screw rod 5 is driven to rotate into, dump valve screw rod 5 promotes Ceramic Balls to fix bar 4 and Ceramic Balls 3 to base 1 moving contact, until Ceramic Balls 3 matches with the arc surface of base 1, compresses, i.e. dump valve closes.Jump ring 6 controls the distance that dump valve screw rod 5 unscrews, and is sealed by inner seal ring 7 when dump valve screw rod 5 rotates.
Described handwheel 8 by flat shim 6 and 10 and self-locking nut 9 be fixed on dump valve screw rod 5 one end.
To sum up, the present invention produces a desired effect.
