Description
Technical field
The utility model relates to a kind of valve, particularly relates to and blocks and the multi-functional valve of anti-backflow a kind of collection, belong to the technical field of valve.
Background technique
In the application of pipeline, stop valve and safety check are most widely used two kinds of valves, and nearly all pipeline all can require in design to meet simultaneously and blocks medium and prevent these two kinds of functions of medium back flow.
In prior art, be stop valve is installed and safety check could meet application substantially simultaneously, and safety check and stop valve are installed simultaneously have that following some is not enough: one, needs enough installation controls; Its two, be equipped with safety check and stop valve simultaneously and cause cost higher; Its three, in use, safeguard and maintenance require higher, engineering is loaded down with trivial details, and potential potential faults is more.
Model utility content
The purpose of this utility model is to solve above-mentioned technical problem, proposes a kind of multi-functional valve.
The purpose of this utility model, will be achieved by the following technical programs:
A kind of multi-functional valve, comprise the valve body of a Y type, especially, described valve body is made up of supplying tube, output tube and the valve body tube that inside is unimpeded, described supplying tube and output tube are positioned on same axis, the angle of the axis of described valve body tube and the axis of output tube is acute angle, and the tube wall between described valve body tube and output tube also runs through bypass tube
Have spool and valve rod in described valve body tube, described spool slides and is arranged in valve body tube, and valve body tube is extended in described valve rod one end, and the other end abuts against with described spool or is separated,
When valve rod and described spool are separated, described spool has slide displacement along valve body tube inwall, and described bypass tube and output tube are mutually unimpeded with valve body tube all the time,
When valve rod and described spool abut against, described spool is fixed, and spool seals with supplying tube and connects.
Preferably, described spool is made up of the guide portion and solid part splicing one mutually.
Preferably, described guide portion with between solid part for being threaded, and the connection part of described guide portion and solid part has spot welding pin.
Preferably, the inwall of described valve body tube is provided with circumferential four directional posts be evenly arranged, and the peripheral wall of described spool has wearing layer, and the peripheral wall of described directional post and spool offsets.
The beneficial effects of the utility model are mainly reflected in:
1. cut-off and check function are gathered all over the body by this valve, reduce cost, save pipeline space, and are convenient to maintenance and safeguard;
2. spool is spliced integrally by guide portion and solid part, and guide portion has leading role, can limit the movement locus of spool, prevents spool from offseting;
3. the inwall of valve body tube is provided with directional post, and the peripheral wall of spool is provided with wearing layer, and directional post plays the effect of guiding, simultaneously the same with wearing layer, adds wear-resisting property.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of multi-functional valve of the utility model;
Fig. 2 is the structural representation of the valve body of Y type in a kind of multi-functional valve of the utility model;
Fig. 3 is the structural representation of spool in a kind of multi-functional valve of the utility model.
Embodiment
The utility model provides a kind of multi-functional valve, has the features such as structure is simple, complete function, with low cost, maintaining is convenient.
As shown in Figure 1, Figure 2 and Figure 3, a kind of multi-functional valve, comprise the valve body of a Y type, valve body is made up of supplying tube 1, output tube 2 and the valve body tube 3 that inside is unimpeded, supplying tube 1 and output tube 2 are positioned on same axis, the angle of the axis of valve body tube 3 and the axis of output tube 2 is acute angle, and the tube wall between valve body tube 3 and output tube 2 also runs through bypass tube 4
Have spool 5 and valve rod 6 in valve body tube 3, spool 5 slides and is arranged in valve body tube 3, and valve body tube 3 is extended in valve rod 6 one end, and the other end abuts against with spool 5 or is separated,
When valve rod 6 is separated with spool 5, spool 5 has slide displacement along valve body tube 3 inwall, and bypass tube 4 and output tube 2 are mutually unimpeded with valve body tube 3 all the time, and now multi-functional valve is in non-return state,
When valve rod 6 abuts against with spool 5, spool 5 is fixed, and spool 5 seals with supplying tube 1 and connects, and now multifunction valve is in cut-off state.
Wherein, spool 5 is made up of the guide portion 7 and solid part 8 splicing one mutually, and preferably, for being threaded between guide portion 7 with solid part 8, and guide portion 7 has spot welding pin with the connection part of solid part 8.Add guide portion, be convenient to carry out leading role to the motion of spool, ensure that spool is according to normal orbiting motion, adopts the dual means of fixation being spirally connected and welding, add the soundness connected between guide portion and solid part, prevent impaired separation in valve core movement process.
In addition, the inwall of valve body tube 3 is provided with circumferential four directional posts 9 be evenly arranged, and directional post 9 offsets with the peripheral wall of spool 5, this directional post can carry out leading role to spool, can increase the wear-resisting property of valve body tube inwall, the peripheral wall of spool 5 has wearing layer, has stronger wear-resisting property simultaneously, prevent spool from using the situation occurring wear damage for a long time, add the working life of multi-functional valve.
Below working procedure and the principle of the utility model multi-functional valve:
Multi-functional valve of the present utility model has two kinds of working staties, and one is non-return state, and one is cut-off state;
When multi-functional valve is in non-return state, valve rod and spool are separated, spool has and is free to slide displacement in valve body tube, flowing medium is flowed into by supplying tube, and flow out along output tube, when there is backflow situation, the flowing medium of backflow is back to valve body tube along output tube and bypass tube, and the flowing medium compressing spool of backflow closes supplying tube, and now non-return has operated;
When multi-functional valve is in cut-off state, only need to promote spool by valve rod and close supplying tube, now valve rod and spool abut against, and spool seals with supplying tube and connects.
By the description of above work process and principle, further illustrate the set that multi-functional valve of the present utility model achieves non-return and cut-off two kinds of functions.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technological schemes formed, and all drops within protection domain of the present utility model.
