Abstract
The utility model relates to a novel check gate valve structure, which comprises a valve body, a valve cap and a valve core, wherein the valve cap is arranged on the valve body, and the valve core is arranged inside the valve body. A spring is arranged on a valve core positioning column which is arranged on the valve core, a bolt hole and a valve positioning hole matched with the valve core positioning column are arranged on the valve cap, a copper ring is arranged at the bottom of the valve core, and a valve body copper ring cavity for the copper ring to be mounted is arranged inside the valve body. The novel check valve structure is simple in structure, convenient in mounting, long in service life, fine in one-way flow stopping and controlling performance and the like.
Description
Technical field
The utility model relates to the pipe fittings field, particularly be the novel non-return gate valve structure that a kind of pipeline connects control.
Background technique
The pipeline pipeline is used for the mobile conveying of liquid medium, connects in the control at pipeline, and connecting flange docks different pipe fittings usually, flowing medium free flow in pipe; Or connect accessory with the gate valve class pipeline is docked.
Existing pipeline connects accessory can only play the connection or the control purpose of damming, mostly be the one-way flow control that straight-through or gate valve structure And can not play liquid medium, therefore design fluid non-return gate valve structure convenient, fast, simple in structure, become the inevitable choice of numerous pipe fitting manufacturing enterprise research and development design.
The model utility content
At the deficiency that exists on the prior art, the utility model purpose is the novel non-return gate valve structure that is to provide a kind of simple in structure, easy for installation, long service life, and the unidirectional control performance that dams is good.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of novel non-return gate valve structure, it comprises valve body, is arranged on the valve gap on the valve body and is arranged on the interior spool of valve body, described spool is provided with the spool locating column, described spool locating column is provided with spring, on described valve gap, be provided with spool positioning hole and the bolt hole suitable with the spool locating column, described spool bottom also is provided with copper band, is provided with the valve body copper band chamber that copper band is installed in described valve body.
Aforesaid a kind of novel non-return gate valve structure wherein, also is provided with packing ring between described valve gap and the valve body, described valve gap by bolt bolt hole adaptive with it with on the valve gap fixed valve body.
The beneficial effects of the utility model are: simple in structure, easy for installation, long service life, the unidirectional characteristics such as control performance is good of damming.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the utility model non-return gate valve structure schematic representation;
Fig. 2 is the valve cover structure schematic representation of the utility model non-return gate valve;
Fig. 3 is the utility model non-return gate valve valve core structure schematic representation;
Fig. 4 is the utility model non-return gate valve body structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Fig. 1 is the utility model non-return gate valve structure schematic representation, and this novel non-return gate valve structure comprises: valve gap 1, packing ring 2, spool 3, copper band 4, valve body 5, spring 6, bolt 7.
The valve cover structure schematic representation of Fig. 2 the utility model non-return gate valve, non-return gate valve valve gap mainly comprises spool positioning hole 1-1 and bolt hole 1-2, spool positioning hole 1-1 and spool locating column 3-1(are as shown in Figure 3) Spielpassung, spring 6 is enclosed within outside the spool locating column 3-1, and its two ends withstand on valve gap 1 and spool 3 two ends respectively.
Fig. 4 is the utility model non-return gate valve body structural representation, and it contains valve body 5, valve flange 5-1, valve body copper band chamber 5-2, valve water intake 5-3, valve water outlet 5-4; Copper band 4 and valve body copper band chamber 5-2 interference fit; Valve gap 1 is coupled to each other by bolt 7 and valve flange 5-1 with valve body 5; The chamber is a great circle camber structure at the bottom of the valve water intake 5-3.
When the utility model uses, when current by valve water intake 5-3, when intake pressure during greater than the elastic force of spool 3 deadweights and spring 6, spool 3 is opened automatically, current are flowed out by valve water outlet 5-4.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
