Description
Technical field
The utility model relates to the hydraulics field, and particularly a kind of one-way valve specifically is a kind of fluid one-way valve or aqueous medium one-way valve.
Background technique
One-way valve is used for control gaseous or liquid can only flow to a direction.At present, the kind of one-way valve is a lot, and the type of one-way valve commonly used has ball-type one-way valve, tapered one-way valve, oscillating-type one-way valve etc.The structure of common one-way valve is made up of valve body, valve seat, spheroid and Returnning spring.Can realize that the control fluid can only flow to a direction, but under the condition of aqueous medium, the easy corrosion of Returnning spring is followed the string, and causes leakage phenomenon; The composite structure of valve body, valve seat, spheroid is not easy dismounting in addition, and the maintain and replace valve core is difficulty relatively.
The model utility content
The purpose of this utility model is: a kind of aqueous medium one-way valve is provided, can controls fluid and flow to a direction.And, have simple in structure, easy to make, easily dismounting, the maintain and replace valve core is more convenient.Overcome the prior art above shortcomings.
The technical solution adopted in the utility model is: aqueous medium one-way valve mainly is made up of valve body, valve seat, spheroid, valve core and valve gap.Import A and outlet B are arranged on the valve body.It is characterized in that: vertical hole is arranged on the valve body, and vertically Kong Yiduan is communicated with import A.Vertically in the hole valve pocket is being arranged, the valve pocket internal fixation has valve seat.The other end screw thread is fixed with valve gap in vertical hole.Valve core is arranged in the bonnet central bore, and valve core and bonnet central bore are slidingly matched.The top of valve core is fixed with spheroid.Valve core can drive spheroid and slide in bonnet central bore, and valve body can be against on the valve seat.
For process, maintenance and easy for installation, outlet B and import A open at grade.Vertical outlet B center line has transverse holes, and transverse holes is communicated with the vertical hole and the outlet B of valve body, and there is plug the transverse holes end.
In order to make the valve core free sliding, valve core has center hole, on the valve core wall intercommunicating pore is arranged, and intercommunicating pore is communicated with the vertical hole of valve core center hole and valve body.Valve core can in time be the fluid infusion of valve core top when sliding.
For improving sealability, reduce leakage, between valve body and valve seat, sealing gasket is arranged.
The beneficial effects of the utility model: the utility model aqueous medium one-way valve, be applicable to the aqueous medium one-way flow, pressure range can be controlled at 1-31.5MPa, good seal performance, leakage rate is lower than 10mL/min.And has easy accessibility, characteristics such as antirust corrosion-resistant, anti-medium pollution.
