Abstract
The utility model belongs to a novel electromagnetic valve in the valve field and consists of an electromagnetic device, an upper valve body, a middle valve body and a lower valve body. The electromagnetic device, the upper valve body, the middle valve body and the lower valve body are coaxially arranged in sequence. A diaphragm is coaxially fixed and arranged between two adjacent valve bodies, and an arc lug boss is arranged in the circumferential direction of the diaphragm. The utility model has simple structure and easy manufacture. The stress conditions of the diaphragm and the valve port are improved, the abrasions of the diaphragm and at the valve port are reduced and the service life of the electromagnetic valve is prolonged by adopting a structure that the arc lug boss is arranged on the circumference of the diaphragm and bending the valve port towards the axes for a certain radian. In addition, the novel electromagnetic valve has with a self-locking function and the firm reliability of the connection between valve bodies is thus enhanced.
Description
Technical field
The utility model belongs to valve field, particularly a kind of electromagnetic valve.
Background technique
Will use solenoid valve that gas flow is controlled in air-transport system, solenoid valve is made of electromagnet portion and valve body usually, and all is fixed with diaphragm in the middle of two adjacent valve bodies.Present solenoid valve both domestic and external adopts the traditional type diaphragm usually, and promptly diaphragm is a thin discs shape.This diaphragm is subjected to the pressure of gas when working and often is in extended state, because the impact resistance of diaphragm is relatively poor, after long-time the use, diaphragm can loss occur and cause inefficacy, and cause sealing and reliability decrease, and the replacing frequency of diaphragm increases, and the life-span of solenoid valve reduces.
In addition, present solenoid valve valve port is right-angle structure, so gas can produce friction with valve port when flowing into pipeline through valve port, increases the resistance of fluid, reduces the flow velocity of gas, and easily causes the solenoid valve inefficacy, reduces its working life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of strong shock resistance of diaphragm is provided, and the wearing and tearing of valve port place are little, the electromagnetic valve that gas fluidity is strong.It is long that this solenoid valve has service time, is difficult for advantages such as inefficacy.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of electromagnetic valve, constitute by calutron, upper valve body, middle valve body and following valve body, this calutron, upper valve body, middle valve body and following valve body is coaxial successively is installed together, the all coaxial diaphragm that is fixed with between two adjacent valve bodies is characterized in that: the week of this diaphragm upwards all is shaped on an arc convex.
And the made arc convex that makes progress in described diaphragm week can be a circle, also can be the arc convex combination of circular concentric formula.
And the made arc convex that makes progress in described diaphragm week is a semi-circular groove.
And the described exterior edge face at the valve port place of valve body down is the arc to the axle center bending.
And described upper valve body, middle valve body and following valve body are the engineering plastics material.
And the week of the bottom surface outer rim of described upper valve body upwards is shaped on annular protrusion, the outside, last plane of middle valve body week upwards be shaped on annular groove, during the annular protrusion of upper valve body can be installed in the annular groove of valve body.
Advantage of the present utility model and beneficial effect are:
1. this electromagnetic valve adopts and make a circle arc convex on the circumference of diaphragm, this arc convex can effectively increase the lifting surface area of diaphragm, improve the stressing conditions of diaphragm when work, reduce its suffered at work stretch effects, make its fluctuating flexible naturally, and prolonged working life of diaphragm, the frequency that has reduced maintenance and changed.
2. the valve port place structure of this electromagnetic valve changes, and valve port is made radian to the axle center bending, has replaced original right angle type valve port.The change of this structure can reduce the friction between gas and the valve port, suffered resistance when both having reduced gas communication has strengthened the fluency of gas flow, has guaranteed carrying out smoothly of transportation work, reduce the loss at valve port place again, prolonged the working life of solenoid valve.
3. the valve body of this solenoid valve adopts engineering plastics to make, and therefore utilizes the characteristic of engineering plastics, and the joint of each valve body can be made groove and projection accordingly, realizes auto-lock function, has increased the firm reliability of connection between each valve body.
4. because the valve body of solenoid valve adopts engineering plastics to make, reduce the use amount of non-ferrous metal, therefore reduced cost of production, improved economic benefit of enterprises.
5. the utility model is simple in structure, make easily, on the circumference of diaphragm, make arc convex and valve port is made structure to the radian of axle center bending by adopting, improved the stressing conditions at diaphragm and valve port place, the wearing and tearing at diaphragm and valve port place have been reduced, prolong the working life of solenoid valve, and the utlity model has auto-lock function, increased the firm reliability of connection between the valve body.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
This solenoid valve is made of calutron 1, upper valve body 2, middle valve body 3 and following valve body 4.This calutron, upper valve body, middle valve body and following valve body is coaxial successively is solidly installed.All coaxially between every two adjacent valve bodies be fixed with a circular film 5.Two adjacent valve bodies install by uniform bolt with the diaphragm that is installed in therebetween.Because calutron and each valve body structure are prior art, no longer give unnecessary details at this.
Present solenoid valve can be the solenoid valve with two chambers (as shown in Figure 3) that is made of upper valve body, middle valve body, following valve body, also can be by the solenoid valve of upper valve body with the following chamber that valve body constituted.Architecture advances of the present utility model all is suitable for above-mentioned two kinds of solenoid valves.
Innovative point of the present utility model is: upwards be shaped on an arc convex 7 week of this diaphragm, this arc convex can be a circle, also can be the combination of the multi-turn arc convex of circular concentric formula.The shape of arc convex can change, and both can be semicircle, also can be ellipse or the like.Be shaped on a circle semi-cylindrical hill in the present embodiment on the diaphragm.
In order to reduce the friction at gas and valve port place, improve flow velocity, the arc 6 to the axle center bending is made in the exterior edge face at following valve body valve port place.As shown in Figure 3, this valve port is made the fish capitiform.
Upper valve body, middle valve body and following valve body are made by the engineering plastics material, use engineering plastics both can make valve body reach original intensity, can reduce the use amount of non-ferrous metal again, reduce production costs, and reduce the waste of metals resources.
