Description
Technical field
It the utility model is related to gas spray valve technical field, more particularly to a kind of Electromagnetic Control valve element opens and closes
Gas spray valve.
Background technology
The B of Chinese invention patent CN 104197027 disclose a kind of monoblock type double valve gas spray valve and its assembling side
Method, the gas spray valve use integrally formed double valve air intake structure, and gas injection flow is big, fast response time, structure letter
Single, easily assembling, assembling difficulty isostructuralism, manufacturability, sealing problem that combined type dual-valve structure brings are avoided, and
Power of the gas pressure on valve element is largely balanced, realize the high-speed response of big flow electromagnetic injection valve, make
Technique is simple, easily realizes industrialization.But because the through hole of connection body cavity rear and front end is opened in body wall
On, body wall is thicker, have compressed the volume of body cavity, so that the latus rectum of valve reduces, influences the flow-passing surface of gas
Product.Meanwhile process this some holes and can also increase manufacturing cost.In addition, dual-valve structure is in order to ensure to seal and move back and forth effect
Fruit, a guide rod is set, guide rod is arranged on the outside of double valve sheet, away from valve element center of gravity, easily causes valve rod and valve pocket eccentric wear,
Influence sealing and guide effect.
Utility model content
For more than above-mentioned prior art deficiency, the utility model provides a kind of double containment gas spray valve, same
In the case of valve body appearance and size, the area of passage of gas can be improved, and reduces manufacturing cost.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of double containment gas spray valve, including：
Valve body, the valve body offer air inlet and gas outlet, valve seat and valve element mounting hole are provided with the valve body；Valve element, it is described
Valve element is slidably matched with the valve element mounting hole, and the valve element is engaged unlatching or the pass for realizing the injection valve with the valve seat
Close；The air inlet connects with the body cavity positioned at the valve element side；The outer peripheral face of the valve element is provided with two annulars
Flange part, the flange part has the sealing surface that is adapted with the valve seat, the portion between two flange parts of the valve element
Dividing formation annular chamber corresponding with the inner surface of the valve body, the annular chamber connects with the gas outlet, and the two of the valve element
Part between individual flange part is provided with guide part, and the guide part is corresponding with the valve element mounting hole, and the valve element is led
Axial diversion groove is offered to portion, the valve core inside offers the flow-guiding channel for the body cavity for connecting the valve element both sides.
Wherein, the flow-guiding channel includes being opened in the axial pass-through holes of the valve element and connected with the axial pass-through holes
Logical radial hole.
Wherein, the guide part of the valve element includes two or more spaced guide rings, the axial diversion
Groove is opened on the side face of the guide ring.
Wherein, guide sleeve is provided with the valve element mounting hole of the valve body, the valve element is slidably matched with the guide sleeve.
After adopting the above technical scheme, having the technical effect that acquired by the utility model：
1) because flow-guiding channel is opened on valve element, flow-guiding channel is processed on valve element than the handling ease on valve body
More, in the case where valve body has same external dimensions, valve element can be done bigger, thus can improve the flow-passing surface of gas
Product, and reduce manufacturing cost.
2) valve rod playing the guiding role is eliminated, the guide part of valve element is arranged between two sealing surfaces, it is simple in construction, lead
Good to effect, solving because valve rod is arranged on one end of valve element, makes the center of gravity of valve element easily cause valve element not on guide part
Eccentric wear, reduce seal spool effect the problem of.
Brief description of the drawings
Fig. 1 is the structure sectional view of the utility model embodiment；
Fig. 2 is the longitudinal sectional view of valve element in Fig. 1；
In figure, 100- valve bodies, 101- air inlets, 102- gas outlets, 200- valve elements, 201- flange parts, 202- guide rings,
203- axial diversion grooves, 204- axial pass-through holes, 205- radial holes.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of double containment gas spray valve, valve body 100 offer air inlet 101 and gas outlet 102, valve body
Valve seat is provided with 100, valve element mounting hole is offered in valve body 100, valve element 200 is slidably matched with valve element mounting hole, valve element 200
It is engaged with valve seat and realizes being turned on and off for above-mentioned injection valve.
As shown in Fig. 2 air inlet 101 connects with the body cavity positioned at the side of valve element 200.The outer peripheral face of valve element 200 is set
Two annular flange parts 201 are equipped with, flange part 201 has the sealing surface being adapted with valve seat.Two flange parts of valve element 200
