Abstract
The invention discloses a kind of low flow resistance check valve with damping structure, it includes housing, valve and joint, shell one end is check valve inlet, the other end of housing is used with joint and is threadedly coupled, the other end of joint is one-way valved outlet, valve is housed in the housing cavity, guide sleeve is installed at the valve inner hole and sealed by sealing ring, throttle orifice is provided with joint, spring is housed on valve, a spring cavity is formed, is an oil passage inside joint, is only capable of penetrating by throttle orifice between the spring cavity and oil passage.The spring cavity is between valve and joint.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, in light weight, good appearance.
Description
Technical field
Particularly suitable frequent in break-make the present invention relates to a kind of line check valve, high-volume hydraulic uses in loop.
Background technology
With the continuous upgrading of hydraulic system, existing hydraulic system requires that flow is big, operating pressure is high, pipeline parts resistance
Small, it is small to produce 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.
The content of the invention
The task of the present invention is that a kind of flow of proposition is big, resistance is small, can buffer shock-absorbing, a kind of band damping structure that weight is small
Low flow resistance check valve.
The task of the present invention is done in such a way that it includes housing, valve and joint, it is characterised in that：Shell one end is
Check valve inlet, using being threadedly coupled, the other end of joint is one-way valved outlet for the other end of housing and joint, in the housing
Valve is housed in chamber, guide sleeve is installed at the valve inner hole and sealed by sealing ring, throttling is provided with joint
Hole, spring is housed on valve, forms a spring cavity, be an oil passage, the spring cavity and oil passage inside joint
Between be only capable of penetrating by throttle orifice.The spring cavity is between valve and joint.The axis direction of the valve upper oil hole
It is parallel with fluid flow direction.
The present invention has the following effects that：This structure have flow is big, flow resistance is small, band damping, prevent product from trembling, making a whistling sound
Cry, reversely end the characteristics of reliable, in light weight, good appearance.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Drawing explanation：1st, joint, 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 passage.
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
Joint is using threaded connection, preferred HB4-3 standard thread forms, and the other end of joint is one-way valved outlet 7, the housing cavity
In valve 4 is housed, the valve inner hole is sealed by sealing ring 3, is provided with throttle orifice 101 on the joint 1, on valve
Equipped with spring 2, a spring cavity 201 is formed, furtherly, the spring cavity is inside joint between valve and joint
One oil passage 202, it is only capable of penetrating 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（Connect shown in arrow）It is parallel, form one
Cleanliness passage, flow resistance can be effectively reduced.
During work, when valve is to left movement, spring cavity is compressed, and internal oil will be flowed out by throttle orifice, produces resistance
The power for hindering valve to move, when valve moves right, spring cavity becomes big, and fluid needs to enter spring cavity by throttle orifice, equally
The power for hindering valve motion is produced, the resistance effectively can prevent valve from trembling, and generation is uttered long and high-pitched sounds.
Product design designs 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, in light weight, good appearance.
Claims (3)
