Abstract
DRV, main body is valve body, it is characterised in that：The valve body upper end is provided with flow-guiding mouth, the valve body lower end is provided with valve seat, the flow-guiding mouth lower end is connected with buffering road, the buffering road is S-shaped, acoustical cotton is enclosed with the outside of the buffering road, buffering road lower end is provided with outside arc valve element, the valve element upper end and is cased with spring, the valve element is arranged on valve seat, and sealing ring is provided between the valve element and valve seat.The utility model design science is reasonable, flow-guiding mouth and being arranged on for the buffering road of S-shaped play a part of reducing pressure by regulating flow effect while also playing reduction noise on valve body, the acoustical cotton set on the outside of simultaneous buffering road more serves Jing Yin effect, it is effectively reduced noise, arc valve element and sealing ring are provided with simultaneously, can preferably it be sealed, it is to avoid medium leakage, adverse current.
Description
Technical field：
The utility model is related to field of chemical equipment, specifically DRV.
Background technology：
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its main function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.Check-valves can also be used to rise to pressure therein
There is provided to the accessory system for exceeding system pressure on the pipeline of supply.Check-valves can be divided mainly into swing check valve and (be revolved according to center of gravity
Turn) and lift check valve (being moved along axis).
Utility model content：
The utility model provides a kind of DRV.
Technical problem to be solved in the utility model is realized using following technical scheme：
DRV, main body is valve body, it is characterised in that：The valve body upper end is provided with flow-guiding mouth, the valve body
End is provided with valve seat, and the flow-guiding mouth is that upper end open is big, and the small turbination of lower ending opening, the flow-guiding mouth lower end connection is set
Buffering road is equipped with, the buffering road is to be enclosed with acoustical cotton on the outside of S-shaped, the buffering road, and buffering road lower end is provided with
Spring is cased with outside arc valve element, the valve element upper end, the valve element is arranged on valve seat, is provided between the valve element and valve seat
Sealing ring.
Guiding gutter is provided with the flow-guiding mouth.
The guiding gutter is arranged in a crossed manner to tilt, and water conservancy diversion is more accurate, slows down flow velocity, while having reducing effect.
Rationally, being arranged on for road of buffering of flow-guiding mouth and S-shaped plays reducing pressure by regulating flow to the utility model design science on valve body
Effect also plays the acoustical cotton set on the outside of the effect for reducing noise, simultaneous buffering road and more serves Jing Yin effect simultaneously,
Noise is effectively reduced, while there is provided arc valve element and sealing ring, can preferably be sealed, it is to avoid medium leakage,
Countercurrently.
Brief description of the drawings：
Fig. 1 is cross-sectional view of the present utility model；
Fig. 2 is overlooking surface structural representation of the present utility model.
Embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1 and Figure 2, DRV, main body is valve body 1, and the upper end of valve body 1 is provided with flow-guiding mouth 2, the lower end of valve body 1
Valve seat 3 is provided with, flow-guiding mouth 2 is that upper end open is big, and the small turbination of lower ending opening, the lower end of flow-guiding mouth 2 is connected with slow
4 are rushed, buffering road 4 is S-shaped, the outside in buffering road 4 is enclosed with acoustical cotton 5, and the buffering lower end of road 4 is provided with arc valve element 6, valve element
Spring 7 is cased with outside 6 upper ends, valve element 6 is arranged on valve seat 3, is provided with sealing ring 8, flow-guiding mouth 2 and sets between valve element 6 and valve seat 3
Guiding gutter 9 is equipped with, guiding gutter 9 is arranged in a crossed manner to tilt, and water conservancy diversion is more accurate, slows down flow velocity, while having reducing effect.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
