Abstract
The utility model discloses a fast closing check valve, including a valve body provided with a water inlet and a water outlet. A valve seat is arranged in the valve body, and a valve cover is connected with the valve body. The axis of the valve seat is not vertical with the axes of the water inlet and outlet of the valve body, and the valve door is sealed with the valve seat. The valve door is connected with the core shaft, and the axis of the core shaft is overlapped with the one of the valve seat; the valve cover is provided with a guiding sleeve, and the core shaft passes the guiding sleeve through a sealing device; a spring is arranged between the valve door and the valve cover. The valve can avoid the appearance of water hammer, and can be closed without sound, has small water tap damage, and is suitable for the system of light water, original water and sewage water.
Description
The utility model belongs to safety check, is specifically related to a kind of quick-closure check valve.
Present disclosed quick-closure check valve 99231596 has two valve bodies up and down, and there is the problem of producing moulding at twice in the structure relative complex, has loss of head during use.
The purpose of this utility model is to provide a kind of valve body that has, and mandrel and valve inleting water, water outlet axis off plumb quick-closure check valve are to address the above problem.
For realizing the purpose of this utility model, the inventor proposes following technological scheme: quick-closure check valve comprises the valve body of bringing the mouth of a river, water outlet into, establish valve seat in the valve body, valve gap is connected with valve body, valve seat axis and valve inleting water, water outlet axis out of plumb, valve and valve base sealing, valve is connected with mandrel, mandrel axis and valve seat dead in line; Establish guide sleeve on the valve gap, mandrel passes guide sleeve by seal arrangement; Establish spring between valve and the valve gap.
This valve can prevent that water hammer from producing, and closes voiceless sound, and loss of head is little, is applicable to clear water, former water and foul sewer system.
Accompanying drawing quick-closure check valve configuration diagram
Embodiment:
As shown in drawings, the water intake 2 of valve body 1 and the axis horizontal of water outlet 3.Valve gap 10 is connected with valve body 1.Valve seat 4 axis and the horizontal axis out of plumb of establishing in the valve body 1.Valve 5 and valve seat 4 sealings, concrete valve 5 comprises valve dish 6, and valve dish 6 is divided into seal ring 7, and seal ring 7 is fixing by seal washer 8.Seal ring 7 and valve seat 4 sealings.Valve 5 is connected with mandrel 9, mandrel 9 axis and valve seat 4 deads in line; Establish guide sleeve 11 on the valve gap 10, mandrel 9 passes guide sleeve 11 by seal arrangement 12, and seal arrangement 12 is 0 RunddichtringO.Establish spring 13 between valve 5 and the valve gap 10.
This valve working principle is: during turn on pump, valve moves to the upper right in the thrust of water inlet, opening of valves, and spring is compressed simultaneously.After the termination of pumping, hydraulic pressure reduces gradually in the pipe, and under the effect of spring, valve is closed gradually; When water velocity approached zero, spring was pushed valve to close fully to.Therefore do not have the aqueous reflux phenomenon, no water hammer produces.Owing to adopt the metal pair rubber seal, good sealing effect.
