Abstract
A mute check valve comprises a valve body, a guide bush, a guide rod type valve disc, a valve base, an O-shaped ring and a spring, wherein the guide bush is arranged in the valve body, a guide rod of the guide rod type valve disc is arranged in the guide bush, the valve base is arranged on the guide rod of the guide rod type valve disc through an inner hole and is connected to the valve body through threads in a matched mode, the O-shaped ring is arranged on the inner end face of the valve base, and the spring is arranged between the guide rod type valve disc and the guide bush. The mute check valve is safe and reliable, stable in operation, free of noise and good in sealing performance and can be widely applied to pipeline systems with the water as the industrial media.
Description
Technical field
The present invention relates to a kind of DRV, can be widely used in pipe-line system that industrial media is water.
background technique
Existing DRV, cushion rubber, because being damaged by excess compression, causes and leaks, and sealing effect is poor, and the system that affects is normally worked, and working life is low.
summary of the invention
The object of the present invention is to provide a kind of safe and reliable, operate steadily, the DRV of noise free, good seal performance.
In order to achieve the above object, DRV of the present invention, comprise valve body, be arranged on the guide bush in valve body, guide rod packs the guide bar valve disc in guide bush into, by endoporus, be arranged on guide bar valve disc guide rod and by screw-thread fit and be connected to the valve seat on valve body, be arranged on the O type circle on valve seat interior edge face, be arranged on the spring between guide bar valve disc and guide bush.
DRV of the present invention, said guide bush, its material is plastics.
DRV of the present invention, its working principle is: when not having MEDIA FLOW to cross valve body, rely on the elastic force of spring, guide bar valve disc is tightly pressed on valve seat O type circle sealing surface and in closed condition.When if the pressure of entrance point is greater than the summation of outlet end pressure and spring force, guide bar valve disc is opened automatically, as long as there is pressure difference to exist, guide bar valve disc is always in opening state, and the pressure extent between entrance point and outlet end has determined the size of guide bar valve disc open degree.When if the summation of outlet end pressure and spring force is greater than entrance point pressure, guide bar valve disc is closed automatically.
DRV of the present invention, its effect is only to allow medium to flow to a direction, and stops mobile in the other direction.Common this valve is automatic operation, and under the mobile fluid pressure action of direction, guide bar valve disc is opened; When fluid flows in the other direction, by the effect of hydrodynamic pressure and spring force, guide bar valve disc is closed automatically, thereby cut off, flows.
DRV of the present invention, because the opening and closing of guide bar valve disc are in a dynamic force balancing system, no matter how the pressure medium of entrance point changes, all operates steadily, and noise free.
DRV of the present invention, its effect is: rely on medium itself to flow and automatic open and close guide bar valve disc, produce destructive water energy to prevent medium from flowing backwards, protection water pump and pipeline miscellaneous equipment.Therefore, the present invention is safe and reliable.
DRV of the present invention, shutoff stroke is short, can realize the quick closedown of valve, and operate steadily, shockproof, noise free, safety.Adopt O type coil structures, rational in infrastructure, good seal performance.
In sum, DRV of the present invention, safe and reliable, operate steadily, noise free, good seal performance.
accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
Fig. 1 is structural representation of the present invention.
embodiment
In Fig. 1, DRV of the present invention, comprise valve body 1, be arranged on the guide bush 2 in valve body, guide rod 7 packs the guide bar valve disc 3 in guide bush into, by endoporus, be arranged on guide bar valve disc guide rod and by screw-thread fit and be connected to the valve seat 4 on valve body, be arranged on the O type circle 5 on valve seat interior edge face, be arranged on the spring 6 between guide bar valve disc and guide bush.
Claims (2)
1. a DRV, it is characterized in that, comprise valve body, be arranged on the guide bush in valve body, guide rod packs the guide bar valve disc in guide bush into, by endoporus, be arranged on guide bar valve disc guide rod and by screw-thread fit and be connected to the valve seat on valve body, be arranged on the O type circle on valve seat interior edge face, be arranged on the spring between guide bar valve disc and guide bush.
2. DRV according to claim 1, is characterized in that, said guide bush, and its material is plastics.
