Abstract
The utility model belongs to the field of valves, and particularly relates to a novel noise eliminating check valve which comprises a valve cover, a valve body, a valve core and a valve rod, and is characterized by further comprising a sealing ring, and the sealing ring is arranged at the bottom of the valve core; an opening is arranged at the lower end of the valve cover; one end of the valve rod is fixed on the valve core in an undetachable way, and the other end of the valve rod is clamped on the opening of the valve cover; and a spring is arranged on the valve rod, one end of the spring is fixed on the valve core, and the other end of the spring is fixed on the valve cover. The novel noise eliminating check valve has the benefits that the sealing ring is additionally arranged between the valve core and the valve body so as to play sealing and buffering roles; when the spring is compressed or restored, the valve rod only needs to move along the opening of the valve cover, thus being very convenient; and the threaded detachable connection between the valve core and the valve rod is changed into an undetachable connection so as to lead the valve core and the valve rod to be connected firmly, therefore, the noise eliminating check valve has better noise eliminating effect and can be used more conveniently.
Description
Technical field
The utility model belongs to valve field, relates in particular to a kind of damping check valve.
Background technique
Damping check valve is used for pipeline or device, and flowing and quick open and close spool (or flap) of dependence medium itself is used to prevent that medium from flowing backwards, and can eliminate water hammer effectively, reduces noise.
Damping check valve comprises valve body, spool, seal ring, valve rod, and spool is a valve part of realizing the fundamental function of direction control, pressure control or flow control by moving of it, and seal ring is positioned at the bottom of spool, is connected with valve body.Offer mounting hole on the existing damping check valve spool, an end of valve rod passes mounting hole and is fixedly connected with spool in this end through nut screwing.Can realize the effect that cooperatively interacts between existing spool and the valve rod, but nut is prone to loose or dislocation, need regularly tighten or change, uses inconvenience; The loosening of nut also has noise simultaneously, weakened the noise elimination effect of damping check valve.
The model utility content
The purpose of the utility model is to overcome the problems referred to above, a kind of noise elimination better effects if is provided, uses damping check valve more easily.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is: a kind of novel damping check valve, comprise valve gap, valve body, spool, valve rod, and it is characterized in that: comprise that also seal ring, seal ring are positioned at the bottom of spool; There is opening the lower end of described valve gap; Described valve rod one end is fixed on the spool, and valve rod is on-disconnectable the connection with spool, and the other end of valve rod is connected to the opening of valve gap; Valve rod is provided with spring, and an end of spring is fixed on the spool, and the other end is fixed on the valve gap.
The described spool of the utility model is a planar.Valve gap and valve body are through being threaded.
The beneficial effect that the utlity model has: between spool and valve body, add seal ring, play sealing and buffering; Length of spring compressed only needs valve rod to move along the valve gap opening when perhaps replying, and is very convenient; With between spool and the valve rod by removable connection of screw thread changing on-disconnectable connection into, spool and valve rod are connected firmly, thereby make damping check valve noise elimination better effects if, use more convenient.
Description of drawings
Fig. 1 is the structural representation of the damping check valve of the utility model;
Wherein, 1 seal ring, 2 spools, 3 valve bodies, 4 springs, 5 valve gaps, 6 valve rods.
Embodiment
Figure is the preferred embodiment of the utility model, below in conjunction with accompanying drawing the utility model is further described: wherein, and 1 seal ring, 2 spools, 3 valve bodies, 4 springs, 5 valve gaps, 6 valve rods.
Referring to Fig. 1, damping check valve comprises valve gap 5, valve body 3, spool 2, valve rod 6, it is characterized in that: also comprise seal ring 1, seal ring 1 is positioned at the bottom of spool 2; There is opening the lower end of described valve gap 5; Described valve rod 6 one ends are on-disconnectable to be fixed on the spool 2 (like riveted joint, welding), and the other end is connected to the opening of valve gap 5; Valve rod 6 is provided with spring 4, and an end of spring 4 is fixed on the spool 2, and the other end is fixed on the valve gap 5.
The described spool 2 of the utility model is a planar.Valve gap 5 and valve body 3 are through being threaded.
The working procedure of the utility model is: when liquid applied malleation to damping check valve, liquid flowed into damping check valve from the below (referring to Fig. 1) of spool 2 and seal ring 1, and fluid pressure promotes spool 2 and moves up with seal ring 1; Valve rod 6 is along moving on valve gap 5 openings, and seal ring 1 breaks away from valve body 3, and promptly damping check valve is opened; Liquid passes valve body 3, valve gap 5 flows out; Because valve gap 5 is fixed, along with moving the length of spring compressed between spool 2 and the valve gap 5 on spool 2, the valve rod 6; Work as liquid return; Be that liquid is when applying negative pressure to damping check valve; Liquid flows into damping check valve from valve gap 5 tops (referring to Fig. 1), fluid pressure promotes valve rod 6 and moves down with spool 2, and pressure spring also promotes valve rod 6, spool 2, seal ring 1 and moves down simultaneously; Very fast seal ring 1 closely is connected with valve body 3, and damping check valve is closed rapidly.
Offer mounting hole on the existing damping check valve spool, an end of valve rod passes mounting hole and is fixedly connected with spool in this end through nut screwing, and nut is prone to loose or dislocation, need regularly tighten or change, and uses inconvenience; The loosening of nut also has noise simultaneously, weakened the noise elimination effect of damping check valve.And spool is that on-disconnectable formula is connected with valve rod in the utility model, and spool and valve rod are connected firmly, thereby makes damping check valve noise elimination better effects if, uses more convenient.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technological scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
Claims (3)
1. a novel damping check valve comprises valve gap, valve body, spool, valve rod, it is characterized in that: comprise that also seal ring, seal ring are positioned at the bottom of spool; There is opening the lower end of described valve gap; Described valve rod one end is fixed on the spool, and valve rod is on-disconnectable the connection with spool, and the other end of valve rod is connected to the opening of valve gap; Valve rod is provided with spring, and an end of spring is fixed on the spool, and the other end is fixed on the valve gap.
