Abstract
The utility model provides a spinning type double-passageway one-way valve group for a reciprocation pump. The spinning type double-passageway one-way valve group is composed of a valve seat, a valve body and a valve column and is characterized in that the valve seat is composed of an inner valve seat and an outer valve seat, an annular liquid passageway is arranged between the inner valve seat and the outer valve seat, and the valve column is arranged at the center of the inner valve seat. The valve body matched with the liquid passageway is composed of an inner valve body and an outer valve body, the inner valve body and the outside of the inner valve seat are sealed in matched mode, the outer valve body and the inside of the outer valve body are sealed in matched mode, the horizontal position of the inner valve and the horizontal position of the outer valve body are fixed through valve body press boards having at least three claws, and the valve body press boards are arranged on the valve column in sleeved mode and is matched with the valve column through a press spring. The spinning type double-passageway one-way valve group has the advantages that according to the design of the annular valve body and the claw-shaped press boards, media can flow out from the outside of the valve body and the inside of the valve body, and overflowing areas are greatly enlarged.
Description
Technical field
The utility model relates to a kind of one-way valve group, particularly a kind of reciprocating pump self-rotary double flow channel one-way valve group.
Background technique
In the prior art, the one-way valve group that reciprocating pump is used generally is made of valve seat, valve plate and valve spring.When valve plate is opened, medium outer effluent runner from valve plate behind runner is discharged.This structure valve plate quality is larger, Flow area is less, so that when design, need to adopt large valve body, high valve plate lift to reach designing requirement, cause pump volume greatly to increase, valve plate impacts the easy fatigue damage of increase, valve plate and sealing surface of seat to valve seat, cause simultaneously pump operation vibration, noise large, affect the operational effect of pump.
The model utility content
The purpose of this utility model is to provide a kind of flow large for the deficiency that solves above-mentioned technology, the reciprocating pump of long service life self-rotary double flow channel one-way valve group.
In order to achieve the above object, the designed reciprocating pump of the utility model self-rotary double flow channel one-way valve group, it is by valve seat, valve plate and valve rod form, it is characterized in that described valve seat is comprised of interior valve seat and outer seat, it is the flow channel for liquids of annular between the interior outer seat, described valve rod is arranged on the central position of interior valve seat, described valve body cooperates with flow channel for liquids, valve body is made of interior outer valve, the outside fitted seal of described inner valve body and interior valve seat, the inboard fitted seal of outer valve and outer seat, described interior outer valve is fixed its horizontal position by the valve body pressing plate that has three pawls at least, and the valve body pressing plate is set on the valve rod and by stage clip and cooperates with valve rod.The characteristics of this structure are by the design of annular valve body and pawl type valve body pressing plate so that medium can have the outside of valve body and the inboard of valve body to flow out, and have greatly increased area of passage.
Further scheme is vertically to be provided with turbine blade on the pawl of described valve body pressing plate, when liquid flows out in the valve seat, and through turbine blade, so that turbine blade obtains horizontal rotating force, band moving valve press plate rotary, and then the rotation of band moving valve.
In order to cut down finished cost, improve sealability, seal by seal ring between the described interior outer valve.
The resulting reciprocating pump of the utility model is with self-rotary double flow channel one-way valve group, and the design of the annular valve body by novelty has increased the passage that flows through of ring-shaped inner part, so that the flow of valve group promotes greatly.Compare with existing reciprocal one-way valve group, identical volume down-off larger, less in identical flow lower volume, thus can effectively reduce the volume of reciprocating pump.Consider simultaneously difficulty of processing, valve body has been divided into inside and outside two-part, so that sealing surface can be processed respectively, reduced difficulty of processing.Moreover, be provided with turbine blade at the valve body pressing plate, by media flow and cooperating of turbine blade improving power, but so that valve body automatic rotation, so that effectively break-in between valve body and the valve seat, when improving sealing effect, also so that the bump fatigue point between valve body and the valve seat can evenly distribute, prolonged the working life of whole valve seat.
