Abstract
The utility model discloses a kind of low flow resistance check valves with damping structure, it includes housing, valve and connector, shell one end is check valve inlet, the other end of housing is used with connector and is threadedly coupled, the other end of connector is one-way valved outlet, valve is housed in the housing cavity, guide sleeve at the valve inner hole is installed and is sealed by sealing ring, throttle orifice is provided on connector, spring is housed on valve, a spring cavity is formed, is an oil passage inside connector, is only capable of penetrating through by throttle orifice between the spring cavity and oil passage.The spring cavity is between valve and connector.The axis direction of the valve upper oil hole is parallel with fluid flow direction.This structure has that flow is big, flow resistance is small, band damping, prevents product from trembling, utters long and high-pitched sounds, reversely ending the characteristics of reliable, light-weight, good appearance.
Description
Technical field
Particularly suitable frequent in break-make the utility model is related to a kind of line check valve, high-volume hydraulic uses in circuit.
Background technology
With the continuous upgrading of hydraulic system, existing hydraulic system requirement flow is big, operating pressure is high, pipeline parts resistance
Small, it is small to generate noise, while requires that weight is small, good appearance.Existing line check valve flow resistance is big, in oil flow height, frequency
It is also easy to produce under the operating modes such as numerous break-make, system pressure mutation or pulsation and trembles, utters long and high-pitched sounds, and structure is more heavy.There is an urgent need to one kind
The Novel check valve that flow is big, resistance is small, vibration-resistant, weight are small can be met.
Invention content
The task of the utility model is that a kind of flow of proposition is big, resistance is small, can buffer shock-absorbing, a kind of band damping that weight is small
The low flow resistance check valve of structure.
The task of the utility model is done in such a way that it includes housing, valve and connector, it is characterised in that：Housing one
End is check valve inlet, and the other end of housing and connector are using being threadedly coupled, and the other end of connector is one-way valved outlet, the shell
Valve in intracoelomic cavity is housed, guide sleeve is installed at the valve inner hole and is sealed by sealing ring, is provided on connector
Throttle orifice equipped with spring on valve, forms a spring cavity, is an oil passage, the spring cavity and fluid inside connector
It is only capable of penetrating through by throttle orifice between channel.The spring cavity is between valve and connector.The axis of the valve upper oil hole
Direction is parallel with fluid flow direction.
The utility model has the following effects that：This structure have flow is big, flow resistance is small, band damping, prevent product from shaking
It quivers, utter long and high-pitched sounds, reversely ending the characteristics of reliable, light-weight, good appearance.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Drawing explanation：1st, connector, 2, spring, 3, sealing ring, 4, valve, 5, housing, 6, check valve inlet, 7, check valve goes out
Mouthful, 101, throttle orifice, 102, oilhole, 201, spring cavity, 202, inner fluid channel.
Specific embodiment
The technical program uses duct type one-way valve structures, and shell one end is check valve inlet 6, the other end of housing 5 with
Connector is using being threadedly coupled, preferred HB4-3 standard thread forms, and the other end of connector is one-way valved outlet 7, the housing cavity
In equipped with valve 4, the valve inner hole is sealed by sealing ring 3, is provided with throttle orifice 101 on the connector 1, on valve
Equipped with spring 2, a spring cavity 201 is formed, furtherly, the spring cavity is inside connector between valve and connector
One oil passage 202 is only capable of penetrating through by throttle orifice between the spring cavity 201 and oil passage 202.
The axis direction of oilhole 102 on the valve 4 and fluid flow direction（It connects shown in arrow）It is parallel, form one
Cleanliness channel can effectively reduce flow resistance.
During work, when valve is to left movement, spring cavity is compressed, and internal oil will be flowed out by throttle orifice, generates resistance
The power that valve is hindered to move, when valve moves right, spring cavity becomes larger, and fluid needs to enter spring cavity by throttle orifice, equally
The power for hindering valve movement is generated, which can be effectively prevented valve and tremble, and generation is uttered long and high-pitched sounds.
Product design is designed according to product cavity variation tendency, everywhere uniform wall thickness；Inside and outside edges and corners are respectively provided with fillet mistake
Degree, in the case where ensureing product compressive resistance, light-weight, good appearance.
