Abstract
The utility model provides a novel check valve, includes valve body, valve gap and cylinder, valve body and valve gap fixed connection, cylinder and valve body contact fixed connection, be provided with the valve shaft in the valve body, a valve seat is arranged inside the valve body, be provided with the rocker on the valve shaft, be provided with the valve clack on the disk seat, the rocker end passes through pivort fixation with the valve clack and is connected, it is outside that valve shaft one end extends to the valve body lateral wall that is provided with the cylinder, the one end that the valve shaft is located the valve body outside is provided with the weight connecting rod, and this weight connecting rod end is provided with the weight, be provided with the cylinder gangbar on the valve shaft, this cylinder gangbar is connected through the pivot with the cylinder. The utility model has the beneficial effects of: this equipment structure is simple, and is with low costs, prevents effectively that the valve clack from following the rotation of the medium vortex and droing, and sealing performance is reliable, simultaneously when the valve clack when closing, through the effect of cylinder, reduce the speed of closing of valve clack, make valve clack slowly closing, have characteristics such as the noise hangs down, the water hammer is little.
Description
First, technical field
The utility model is related to a kind of valve, more particularly to a kind of non-return valve.
2nd, background technology
Check-valves has including two kinds of structures of swing type and lift, and current swing check valve rocking bar passes through one with valve body
Long pin shaft, rocking bar rotates with long pin shaft as rotary shaft in valve body, and flap passes through a short pin shaft attachment valve with rocking bar
Lobe makees opposing oscillatory with short pin shaft as rotary shaft with rocking bar, while flap is pasted with valve body sealing surface in the presence of pressure medium
Close sealing function, swing check valve when in use, flap open and closing course in, by rocking bar endoporus and long pin shaft
Rotate, while flap endoporus rotates with short pin shaft, the rocking bar endoporus and flap bore wear of generation cause rotation
Opening formula check-valves sealing property reduces shortening its service life, and due to flap own wt, rocking bar and flap endoporus are ground into ellipse
Circular hole, therefore easily cause flap and be not closed completely with sealing surface, make swing check valve fail, after swing check valve failure then
Cannot primer liner control effect, additionally, when medium flows backwards, flap can quick closedown and valve seat produce collision, noise height,
Water hammer is big.
3rd, utility model content
In order to overcome now valvular weak point, the utility model to provide a kind of non-return valve.
What the technical solution of the utility model was realized in.
A kind of non-return valve of this programme, including valve body, valve gap and cylinder；The valve body is fixedly connected with valve gap；Institute
State cylinder to be fixedly connected with valve outer wall, valve shaft is provided with the valve body, valve seat is provided with the valve body, on the valve shaft
Rocking bar is provided with, flap is provided with the valve seat, the rocking bar end is fixedly connected with flap by bearing pin；The valve shaft one
End extends to and is provided with outside the body wall of cylinder；The valve shaft is located at the one end outside valve body and is provided with weight connecting rod,
The weight connecting rod end is provided with weight；Cylinder linkage is provided with valve shaft between the weight connecting rod and valve outer wall
Bar, the cylinder gangbar is connected with cylinder by rotating shaft.
The weight is used to drive valve shaft rotation to be brought into close contact flap and valve seat.
The valve body and valve gap are threadedly coupled.
The cylinder is used to reduce the translational speed of flap when flap is moved to valve seat.
It is of the present utility model to be beneficial in that：The device structure is simple, low cost, effectively prevents flap to be vortexed with medium
Rotation comes off, sealing property reliability, while working as flap when closed, by the effect of cylinder, reduces the closing velocity of flap, makes
Flap slowly closing, with noise it is low, water hammer is little the features such as.
The weight that the present invention is arranged improves the sealing of valve..
4th, illustrate
Fig. 1 is front view of the present utility model.
Fig. 2 is front sectional view of the present utility model.
Fig. 3 is top view of the present utility model.
5th, specific embodiment
Below in conjunction with the accompanying drawings brief description is made to specific embodiment of the present utility model.
A kind of non-return valve as depicted, including valve body 1, valve gap 7 and cylinder 9；The valve body 1 and valve gap 7 are fixed
Connection；The cylinder 9 is fixedly connected with the outer wall of valve body 1, is provided with the valve body 1 in valve shaft 6, the valve body 1 and is provided with valve
Seat 5, is provided with rocking bar 4 on the valve shaft 6, flap 2 is provided with the valve seat 5, and the end of the rocking bar 4 passes through pin with flap 2
Axle 3 is fixedly connected；The one end of the valve shaft 6 extends to and is provided with outside the side wall of valve body 1 of cylinder 9；The valve shaft 6 is located at valve body 1
Outside one end is provided with weight connecting rod 10, and the end of weight connecting rod 10 is provided with weight 11；The weight connecting rod 10
Cylinder gangbar 8 is provided with the valve shaft 6 between the outer wall of valve body 1, the cylinder gangbar 8 is connected with cylinder 9 by rotating shaft.
The weight 11 is used to drive the rotation of valve shaft 6 to be brought into close contact flap 2 and valve seat 5.
The valve body 1 and valve gap 7 are threadedly coupled.
The cylinder 9 is used to reduce the translational speed of flap 2 when flap 2 is moved to valve seat 5.
Specific works mode：The utility model is arranged on when playing fluid check function on pipeline, when flap 2 is being closed
When, air pressure increases in cylinder 9, reduces the noise that valve is produced when closed, and water hammer is little；Simultaneously in the presence of weight 11,
The cooperation of flap 2 and valve seat 5 is even closer, improves the sealing of valve.
One embodiment of the present utility model has been described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all to be made according to the utility model application range
Impartial change with improve etc., all should still belong within patent covering scope of the present utility model.
