Abstract

This utility model provides a kind of excessively stream buffer-type DRV, including valve body, valve seat, flap, valve rod and the baffle of valve inner are arranged on, baffle is integrated setting with valve body, and valve seat is arranged on the front end of valve inner, bushing is provided between valve rod and baffle, one end of valve rod is inserted in bushing, and the other end of valve rod is connected with flap, and spring is provided between flap and bushing, the front end of flap has been bolted pressing plate, is provided with sealing ring between the two ends of flap front end and pressing plate.This utility model small volume, it is lightweight, sealing ring is pushed down using pressing plate, so that sealing ring changes convenient, it is time saving and energy saving, while pressing plate is buffer-type pressing plate, when the normal excessively stream of valve works, the water hammer produced as fluid pressure difference is excessive can be reduced, it is to avoid the infringement that valve is caused as impulsive force is excessive, realize the dual function of quiet non-return and cushion plugs.

Description

A kind of excessively stream buffer-type DRV
Technical field
This utility model is related to check-valves manufacture field, more particularly to a kind of excessively stream buffer-type DRV.
Background technology
Check-valves are the primary elements that fluid controls engineering, using quite varied.It plays guarantor by preventing fluid countercurrent current Protect the effect of other fluid machineries and pipeline safety.At present conventional check-valves mainly have DRV, muffling check valve, right Clip check-valves, they all have runner in various degree and have some setbacks, and resistance is big, and the loss of flood peak is larger, after long-time use by In wearing and tearing or getting rusty, valve rod is resetted and is obstructed with valve pocket friction increase, flap, and sealing can decline.
The content of the invention
This utility model is exactly directed to above technical problem, there is provided a kind of excessively stream buffer-type DRV.
This utility model for achieving the above object, is employed the following technical solutions:A kind of excessively stream buffer-type DRV, bag Valve body is included, valve seat, flap, valve rod and the baffle of valve inner is arranged on, baffle is integrated setting with valve body, and valve seat is arranged In the front end of valve inner, bushing between valve rod and baffle, is provided with, one end of valve rod is inserted in bushing, the other end of valve rod It is connected with flap, between flap and bushing, is provided with spring, the front end of flap has been bolted pressing plate, the two ends of flap front end Sealing ring is provided between pressing plate.
The pressing plate is buffer-type pressing plate.
Compared with prior art, the beneficial effects of the utility model are:This utility model small volume, it is lightweight, using pressure Plate pushes down sealing ring so that sealing ring changes convenient, time saving and energy saving, while pressing plate is buffer-type pressing plate, in the normal excessively stream of valve During work, the water hammer that can reduce as fluid pressure difference is excessive and produce, it is to avoid the infringement that valve is caused as impulsive force is excessive, Realize the dual function of quiet non-return and cushion plugs.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As illustrated, a kind of excessively stream buffer-type DRV, including valve body 1, the valve seat 2, valve being arranged on inside valve body 1 Lobe 3, valve rod 4 and baffle 5, baffle 5 are integrated setting with valve body 1, and valve seat 2 is arranged on the front end inside valve body 1, valve rod 4 Bushing 6 is provided with and baffle 5 between, one end of valve rod 4 is inserted in bushing 6, and the other end of valve rod 4 is connected with flap 3, flap Spring 7 is provided between 3 and bushing 6, the front end of flap 3 is fixed with pressing plate 9, two ends and the pressing plate 9 of 3 front end of flap by bolt 8 Between be provided with sealing ring 10.
The pressing plate 9 is buffer-type pressing plate.
This utility model is opened by the power of media flow, and flap 3 moves up and down along cavity axis in valve body 1,3 He of flap Spring 7 is provided between bushing 6, pressing plate 9 is buffer-type pressing plate, and water hammer pressure, sealing can be effectively reduced during its quick closedown Can be good, form muting function.It has small volume, lightweight, and fluid resistance is little, opens and closes flexible, endurance, life-span length etc. excellent Point.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received The restriction of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without Improvement directly applies to other occasions, within protection domain of the present utility model.
