Description
Technical field
The utility model is related to gas spray valve technical field, more particularly to a kind of Electromagnetic Control valve element is opened and closed
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 uses integrally formed double valve air intake structure, and gas injection flow is big, fast response time, structure letter
Single, easily assembling, it is to avoid assembling difficult isostructuralism that combined type dual-valve structure is brought, manufacturability, sealing problem, 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, manufacturing cost can also be increased by processing this some holes.
Utility model content
For a kind of more than above-mentioned prior art not enough, double containment gas spray valve of the utility model offer, 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 offers in air inlet and gas outlet, the valve body and is provided with valve seat and valve pocket；Valve element, the valve element bag
Include valve rod and be arranged at the conjuncted valve block of the valve rod, the valve stem slides are installed in the mounting hole of the valve seat, described
Body valve block is engaged with the valve seat and realizes being turned on and off for the injection valve；The air inlet is with being located at the conjuncted valve block
The body cavity connection of side；The conjuncted valve block include body and be arranged at two of the body outer peripheral face it is annular
Flange part, the flange part have part between the sealing surface that is adapted with the valve seat, described two flange parts with it is described
The inner surface formation annular chamber of valve body, the annular chamber is connected with the gas outlet, and the body offers axial pass-through holes,
The axial pass-through holes connect the body cavity of the conjuncted valve block both sides.
Wherein, the conjuncted valve block is set to one with the valve rod.
Wherein, the conjuncted valve block sets and linked together with the valve rod split.
After adopting the above technical scheme, having the technical effect that acquired by the utility model：
On the body that the conjuncted valve block of valve element is opened in due to axial pass-through holes, thereon processing axial pass-through holes than
Handling ease is more on valve body, in the case where valve body has same external dimensions, and the conjuncted valve block of valve element can have what is done
It is bigger, thus the area of passage of gas can be improved, and reduce manufacturing cost.
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；
Fig. 3 is the longitudinal sectional view of valve element in another embodiment；
In figure, 100- valve bodies, 101- air inlets (air inlet position instruction is adjusted in figure), 102- gas outlets, 103- valve pockets,

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of double containment gas spray valve, valve body 100 offers air inlet 101 and gas outlet
102, valve seat 104 and valve pocket 103 are provided with valve body 100.Valve element 200 includes valve rod 201 and is arranged at the conjuncted valve of valve rod 201
Piece, valve rod 201 is slidably mounted in the mounting hole of valve pocket 103, and conjuncted valve block is engaged with valve seat 104 and realizes the injection valve
It is turned on and off.
Air inlet 101 is connected with the body cavity positioned at conjuncted valve block side, in the present embodiment, conjuncted valve block and valve rod
201 are set to one.Conjuncted valve block includes body 202 and is arranged at two annular flange parts of the outer peripheral face of body 202
203, flange part 203 have part between the sealing surface that is adapted with valve seat 104, two flange parts 203 with valve body 100
Surface forms annular chamber, and the annular chamber is connected with gas outlet 102, and body 202 offers axial pass-through holes 204, axially passes through
Through hole 204 connects the body cavity of the conjuncted valve block both sides.
As shown in figure 3, for the ease of manufacture, as another embodiment, conjuncted valve block can also split with valve rod 200
The mode for manufacturing and being fixedly connected eventually through interference or welding etc. links together.
