Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is the corrosion-proof solenoid valve providing a kind of good sealing effect.
For achieving the above object, the utility model provides following technological scheme: comprise valve body, bonnet, electromagnetic assembly, valve rod and diaphragm, electromagnetic assembly is installed in above valve body by this bonnet and electromagnetic assembly drives with valve rod and coordinates, described diaphragm is installed on valve rod lower end and between bonnet and valve body, the runner passed through for fluid is provided with in described valve body, this runner is provided with liquid entering hole and liquid outlet, it is characterized in that: between described valve body and bonnet, be provided with chamber of confluxing, described diaphragm chamber of confluxing is divided into epicoele and cavity of resorption, described runner comprises by the feed liquor runner of cavity of resorption and liquid entering hole UNICOM with by the fluid runner of cavity of resorption and liquid outlet UNICOM, described feed liquor runner and all L-shaped setting of fluid runner and towards the opposite, described feed liquor runner and the position of cavity of resorption UNICOM are as First Transition mouth, ferry is crossed as second in described fluid runner and the position of cavity of resorption UNICOM, described First Transition mouth and second cross ferry all corresponding with diaphragm and when valve rod declines while fit to form with diaphragm and seal.
By adopting technique scheme, arrange two runners and two cross ferries and adopt diaphragm to seal simultaneously, even if there is distortion or gap because being corroded for a long time in diaphragm side like this, crossing between ferry and diaphragm still for being sealed and matched of opposite side, ensure the normal work of corrosion-proof solenoid valve, the liquid revealed then can be gathered in epicoele.
The utility model is set to further: the position that described valve body is corresponding with diaphragm outboard end is provided with swing Seal cage, and this swing Seal cage is respectively arranged with diaphragm to joining the secondary seal face forming and seal at the relative First Transition mouth of diaphragm and the second opposite side crossing ferry.
By adopting technique scheme, to the secondary seal face laminating swinging Seal cage when being subject to outside diaphragm being initially subject to larger fluid impact, fluid can not be revealed from diaphragm outboard end, even if still can keep sealing under ensureing large pressure fluid, optimizes sealing effect further.
The utility model is set to further: described diaphragm and First Transition mouth and second are crossed position corresponding to ferry and be respectively provided with opening crosses ferry respectively arcuate segment towards First Transition mouth and second.
By adopting technique scheme, arcuate segment increases First Transition mouth and second and crosses the fluid at ferry and the area of contact of diaphragm, reduces per unit contact area pressure, namely reduces the deformation quantity of diaphragm, ensure sealing effect while extending its working life.
The utility model is set to further: described valve body is crossed between ferry at First Transition mouth and second and is provided with the manifold coordinated with diaphragm seal, the position that described diaphragm is corresponding with manifold is provided with the pressure relief plate that can extrude and open, and described manifold is when pressure relief plate is opened and epicoele UNICOM.
By adopting technique scheme, when due to pressure excessive, when seepage is carried out in the gap of fluid inside diaphragm and between valve body, then manifold can be gathered in, being full of by fluid in manifold, can open pressure relief plate and make liquid stream to epicoele, guarantee will make fluid continue the runner of creeping to the other end along gap due to pressure, ensures overall sealability.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
