Description
Technical field
Patent of the present invention relates to dental medical apparatus, is specifically related to the water route one-way valve that dental medical apparatus is used.
Background technique
Dental medical apparatus is as ultrasonic scaling machine, piezosurgery osteotomy machine etc., its clean one's teeth or deep working procedure in, need to carry out synchronous cleaning and sterilization to affected part, liquid medicine sprays to affected part through handle from operation tip, this just need to be provided with ，Jiang water source, a water supply water route at device interior and guide handle into.Need to be provided with switch on the water supply water route, to realize the switch in water supply water route.What the switch arranged on existing water route was commonly used is solenoid valve, uses solenoid valve to coordinate with electric pump, and during work, solenoid valve is opened, electric pump turns round, and water route starts to supply water to handle; While quitting work, closed electromagnetic valve, electric pump shut down, and no longer supply water in water route.Use the mode of solenoid valve to guarantee that solenoid valve and electric pump coordinate maintainability by complicated circuit design, solenoid valve can increase the certain power consumption of equipment simultaneously.The another kind of switch arranged on water route can use one-way valve, when the hydraulic pressure of water inlet reaches certain value, and one-way valve opens, water route water supply start; When intake pressure, during lower than certain value, one-way valve is closed automatically, and water route stops supplying water.Existing one-way valve due to the lock waterstop ring and lock water-bound design unreasonable, while equipment work easily occurring, water route can not normal water supply or equipment while quitting work, handle insecure situation such as leak.
Summary of the invention
The technical problem to be solved in the present invention is to provide the water route one-way valve that a kind of structure optimization, dental medical apparatus that reliability is higher are used.
For solving above technical problem, the water route one-way valve that dental medical apparatus provided by the invention is used, comprise the bonnet and the bottom flange that connect together, set out the mouth of a river on described bonnet, be provided with water intake on described bottom flange, on, bottom flange connects together in the middle of rear and forms valve pocket, its innovative point is: on the direction in described valve pocket from the bonnet to the bottom flange, be set with successively the conical seal ring with through hole, the ring-type valve pocket, spring and spool, be provided with projection in described ring-type valve pocket and the valve pocket inner chamber be divided into to epicoele and the cavity of resorption communicated, described epicoele bottom is complementary for horn shape and conical seal ring, described spool is by valve core case, valve rod and brake hoop form, described valve core case diameter is greater than the diameter of described spring and is slightly less than the cavity of resorption diameter of valve pocket inner chamber, the length of described spool is less than the height of valve pocket, described spool can Vertical direction move in valve pocket, the valve rod of described spool is through spring, the through hole of valve pocket inner chamber and conical seal ring, the diameter of the brake hoop of described spool is greater than the through-hole diameter of described conical seal ring.
In order more to be fixed on conical seal ring on spool, be provided with near brake hoop one end the snap ring that a diameter is greater than the projection of cone seal ring through hole on described valve rod, the distance between described snap ring and brake hoop equals the height of described conical seal ring.
Preferably, be provided with the snap ring of a projection on described valve rod near brake hoop one end, the end that described cone seal loop diameter is little offers the ring-shaped step of the indent of mating with described snap ring size.
In order to strengthen the sealing of one-way valve, the outside, described valve pocket two ends offers respectively ring-shaped step, is respectively installed with " O " RunddichtringO on ring-shaped step.Preferably, described conical seal ring and " O " shape seal ring are silica gel sealing ring.
For the ease of the fixing of spring and assembling, the valve core case of described spool is the cross partition structure, at each dividing plate, near a side of described spring, offers the step be complementary with spring inside diameter.
Preferably, offer respectively the bayonet socket cooperatively interacted on described bottom flange and bonnet, bottom flange and bonnet are connected together by bayonet socket.
For the ease of the installation of water route water pipe, the water intake arranged on the water outlet arranged on described bonnet and described bottom flange for outside outstanding column structure, offers circular protrusion on water outlet and water intake.
The invention has the advantages that: in the water route one-way valve that dental medical apparatus is used, conical seal ring, ring-type valve pocket, spring and spool closely cooperate, and when water route is closed, on conical seal ring and valve pocket, the area of contact of cavity wall is larger, and sealing is more reliable.Spring force in one-way valve can be set according to the requirement of water supply pressure, and when water pressure surpasses the elastic force of spring, spring inwardly shrinks, and one-way valve is connected water supply start.
At valve pocket outside suit " O " RunddichtringO, can strengthen the sealing of one-way valve, prevent that the one-way valve edge from having water to leak.The valve core case of spool is the cross partition structure, offers respectively the bayonet socket cooperatively interacted on bottom flange and bonnet, and these designs allow one-way valve more be convenient to assembling.
In order to be arranged on the water pipe difficult drop-off on one-way valve, by the water intake arranged on the water outlet that arranges on valve gap and described bottom flange, be designed to outwards outstanding column structure, offer circular protrusion on water outlet and water intake.
