Description
Technical field
The utility model relates to valve field, particularly relates to a kind of clamp mute check-valve.
Background technique
Safety check is also known as one-way valve or check valve, and its effect prevents the medium in pipeline from flowing backwards, and its application is very extensive, and especially in the application process of the devices such as pump class device and plumbing equipment, safety check is indispensable especially.At present conventional safety check mainly contains DRV, damping check valve, Wafer Check Valves, all also exists that runner has some setbacks, resistance large in various degree, and loss of head is larger; Owing to wearing and tearing or getting rusty after long-time use, valve shaft and axle sleeve rub and increase, and valve disc resets and is obstructed, the shortcoming that sealing declines.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of clamp mute check-valve, comprise valve body, valve pocket, valve gap ring, valve seat, axle sleeve, valve shaft, spring, valve disc, self oiling bearing, fairshaped valve pocket is formed in described valve body, be positioned at valve pocket front portion in described valve body and be provided with valve seat, described valve body rear portion is provided with valve gap ring, axle sleeve is provided with in the middle of described valve gap ring, self oiling bearing is provided with in described axle sleeve, described valve shaft is arranged in self oiling bearing, described valve shaft front end is provided with valve disc, is provided with spring between described valve disc and axle sleeve.
The beneficial effects of the utility model are: valve pocket inside adopts Streamline Design, and resistance is little, and loss of head is little, is provided with self oiling bearing in axle sleeve, and valve shaft and axle sleeve will be caused to rub because wearing and tearing or getting rusty and increase, valve disc resets smooth and easy, good airproof performance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, valve body; 2, valve pocket; 3, valve gap ring; 4, valve seat; 5, axle sleeve; 6, valve shaft; 7, spring; 8, valve disc; 9, self oiling bearing.
As shown in Figure 1, fairshaped valve pocket 2 is formed in described valve body 1, be positioned at valve pocket 2 front portion in described valve body 1 and be provided with valve seat 4, described valve body 1 rear portion is provided with valve gap ring 3, be provided with axle sleeve 5 in the middle of described valve gap ring 3, be provided with self oiling bearing 9 in described axle sleeve 5, described valve shaft 6 is arranged in self oiling bearing 9, described valve shaft 6 front end is provided with valve disc 8, is provided with spring 7 between described valve disc 8 and axle sleeve 5.
When current pass through, the spring 7 between valve disc 8 and axle sleeve 5 is compressed, and moves after valve disc 8, valve opening, when valve water inlet place hydraulic pressure is less than normal or when cutting off the water, spring is stretched for 7 times, makes valve closing, because valve pocket 2 inside adopts Streamline Design, resistance is little, and loss of head is little, is provided with self oiling bearing 9 in axle sleeve 5, valve disc 8 resets smooth and easy, good airproof performance.
Be described in detail of the present utility model by embodiment above, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
