Description
Technical field
The utility model relates to solenoid valve, especially relates to a kind of opening and closing of supplying with the Electromagnetic Control automobile cooling, thus the automobile water-based way solenoid valve of heating for automobile urea box mechanism.
Background technique
Solenoid valve is a kind of commonly used with the valve of electromagnetic force as driving force, is widely used for the fields such as automobile, oil, metallurgy.Valve body, valve gap, diaphragm assembly, coil assembly, moving iron core and static iron core are arranged in the solenoid valve.When the electromagnetic coil of solenoid valve was switched on, moving iron core was by adhesive, and spring is simultaneously compressed, valve rod is separated with spool mesopore (pilot hole), fluid moment of spool epicoele, spool upwards floated under the effect of upper and lower cavity pressure reduction fast from the mesopore release, and solenoid valve is opened.During the coil blackout of solenoid valve, valve rod is closed the spool mesopore under the effect of spring force, and promotes spool to moving down, and seals fluid output, closed electromagnetic valve.
At present, because of the versatility of considering that product uses, the working pressure of existing solenoid valve is all larger, generally all more than 1.0MPa, that have even can reach 20.0MPa, for adapting to this hyperbaric environment, valve body and valve gap generally all are as material take stainless steel or brass, in actual production process, general smart casting or the Forging Technology of adopting, for satisfying working pressure needs and processing technology requirement, the thickness of valve body and valve gap generally has 5mm, can reach 8mm partly, can cause like this volume of solenoid valve large, Heavy Weight, the raw material that consume stainless steel or brass are many, and manufacturing procedure is loaded down with trivial details, process-cycle is long, and cost of production is higher.
At present, the waterway electromagnetic valve of using on the automobile generally is to adopt the internal thread Placement with outside the connection, so just must increase at the valve body two ends of solenoid valve two sections metal threaded pipes is connected with solenoid valve again, on the automobile for preventing thread looseness, produce leakage situation, generally can weld together valve body and threaded pipe.The valve gap of waterway electromagnetic valve also is to adopt to be threaded with the Placement of plunger tube group, be Leakage prevention, the rubber ring seal of general employing O shape, the long-time use easily of this O shape rubber washer worn out, easily produce and leak, so need frequent replacing, these all can increase installation time and the extra cost of production of solenoid valve.
Summary of the invention
The purpose of this utility model is to provide a kind of and is guaranteeing that weight is lighter, simple in structure under Product Safety, the reliability prerequisite, cost is lower, the more reliable automobile water-based way solenoid valve of sealing.
The purpose of this utility model is achieved in that
A kind of automobile water-based way solenoid valve, comprise valve body, valve gap, diaphragm, fixed base, moving iron core, spring, coil, static iron core, plunger tube, rubber plug and mounting bracket, be provided with the valve intake pipe at valve body, main valve hole and valve outlet pipe, feature is: the lower end of plunger tube extend into downwards in the valve cover hole on valve gap top of " eight " font, and the top of valve gap and the outer wall of plunger tube are fixed together by seal welding, the diaphragm that is fixed between valve gap and the valve body is divided into the upper chamber of top and the lower chambers of below with the chamber that seals, above in the middle of diaphragm fixed plate and fixed base are installed successively, fixed base is plane contact with the rubber plug that is fixed on below the moving iron core, rubber plug can seal the pilot hole on the fixed base, extension spring is enclosed between moving iron core and the fixed base, the extension spring top is fixed on the moving iron core, the bottom of extension spring is fixed on the fixed base, diaphragm turns over riveting with fixed plate by fixed base and pad and is in the same place, coolant pressure by upper chamber and lower chambers is poor, the pressure of Compress Spring, a plurality of effects of making a concerted effort such as the pulling force of extension spring make the diaphragm opening and closing, realize opening of cooling liquid, disconnected; Pilot hole can be communicated with upper chamber and main valve hole, be processed with the by-pass hole that is communicated with lower chambers and upper chamber at diaphragm, lower chambers, by-pass hole, upper chamber, pilot hole and main valve hole consist of leader channel, and valve intake pipe, lower chambers, main valve hole, valve outlet pipe consist of cooling passage.
Directly be processed with flexible pipe on by the valve intake pipe that strengthens the valve body that Nylon makes and be tightly connected and not threaded valve water inlet interface, on the valve outlet pipe of valve body, directly be processed with flexible pipe and be tightly connected and not threaded valve water outlet mouthpiece.
At the valve gap cover mounting bracket is arranged, four long bolts pass mounting bracket, valve gap, diaphragm and valve body from top to bottom successively, four long bolts and four nuts are fixed together mounting bracket, valve gap, diaphragm and valve body together, and fastening good diaphragm can guarantee that the peripheral sealing of valve gap and valve body is water-tight.
The aperture of by-pass hole is the 1/3--1/2 in the aperture of pilot hole.
The utility model and existing technology difference are:
1, the working pressure of considering auto pump is not more than 0.4MPa, valve gap adopts the stamping part of δ 2.0mm stainless steel materials, just can satisfy Security, reliability requirement that waterway electromagnetic valve uses at automobile, compare with the existing valve gap of producing with the die casting mode and to have reduced raw-material consumption, reduced the weight of product, simplify processing technology, thereby reduced cost of goods manufactured.
2, because the top of valve gap and the outer wall of plunger tube are fixed together by seal welding, cancelled the O shape rubber washer that uses in existing valve gap and the plunger tube sealing installation process, also just do not existed because of the aging leakage problem that causes of O shape rubber washer.
3, valve body has adopted enhancing Nylon spare.Because waterway electromagnetic valve is less in the working pressure that automobile bears, the body strength that strengthens the Nylon material namely satisfies the working pressure needs of waterway electromagnetic valve, reduced again the weight of valve body, the coil of valve gap top and the weight of static iron core two parts account for about 80% of waterway electromagnetic valve gross weight in addition, and all be to be supported by valve gap, this part weight is connected with the screw threads for fastening of mounting bracket by valve gap and all is transmitted on the mounting bracket, avoid coil and static iron core to the jerk of the valve body of enhancing Nylon, guaranteed the sealing requirements that valve gap and valve body are installed.
4, because automobile is in movement process, solenoid valve often is in vibrating state, solenoid valve still adopts the mode that is threaded commonly used at present to produce easily leakage with the Placement of outside, so the utility model is directly made the valve intake pipe at existing solenoid valve two ends and valve outlet pipe and valve body the integral body of an enhancing Nylon material, be processed with respectively at two of valve intake pipe and valve outlet pipe with flexible pipe and be tightly connected and not threaded valve water inlet interface and valve water outlet mouthpiece, the risk of leakage that may occur when so just having avoided thread seal, the while has also alleviated the weight of intake pipe and outlet pipe.
Therefore, the utility model is by changing material and the processing technology of the parts such as valve gap, valve body, valve intake pipe and valve outlet pipe that have waterway electromagnetic valve now, namely satisfied the particularity requirement of automobile water-based way solenoid valve, simultaneously reduced by a relatively large margin again the raw-material consumption of product, reduced product weight, simplified the processing technology of product, thereby reached the applicability that improves product and the purpose that reduces product cost.
