Abstract

The utility model discloses a manufacturing technology of an electromagnetic valve product which comprises a valve body (1), a valve cavity (9), a valve port (8) and a valve cover (4), wherein the valve cover (4) is connected with an electromagnetic loop (5), and a movable iron core (6) is arranged in the center of the electromagnetic loop (5); a spring (7) is arranged at the upper end of the movable iron core (6), and a seal gasket (10) is arranged at the lower end of the movable iron cover (6); a seal gasket (11) is positioned right above the valve port (8); a lower port of the valve port (8) is provided with a throttle lever (11), and the throttle lever (11) and the valve body (1) are fixedly connected; the tail end of a handle part of the throttle lever (11) is provided with screw threads and rotatably connected with the valve body (1); and a frustum-shaped throttle head (12) is arranged at the upper end of the throttle lever (11). In the product, the throttle lever is arranged ina bottom shell of the valve body, thereby not only avoiding increasing the appearance volume of the product, but also reducing the consumption of raw materials of the valve body and being further goodfor flow or pressure adjustment operations in the application process of a gas-liquid system.

Description

The throttling type solenoid valve

Technical field

The utility model relates to a kind of solenoid valve product manufacturing technology, especially refers to the throttling arrangement structure of spool flow and pressure.

Background technique

Solenoid valve is a kind of application area gas-liquid Automatic Control Component extremely widely, the main structure of its traditional product as shown in Figure 1: after electromagnetic coil energising produced magnetic field, the moving magnetic field force induced effect of iron core overcame on the spring force and moves, and opens valve port fully; After the outage, moving iron core is subjected to spring action close port again.Therefore this class solenoid valve product has only and opens fully and close two kinds of working staties fully, and its flow value is set when dispatching from the factory, and the user can't change voluntarily; So when technological process requires to change flow or pressure, then can only satisfy adjusting by the mode of a throttle valve of serial connection to gas-liquid channel.But, after solenoid valve and throttle valve are connected in series, volume increase, cost are risen, what bother most is that the system works reliability descends greatly, the control system application of the adjusting gas-liquid flow that often is difficult to satisfy the demand is required.

The model utility content

The technical problems to be solved in the utility model is to overcome existing general solenoid valve product not have the defective and a deficiency of throttling function, provide a kind of solenoid valve product of self tool throttling function to society, the control system of often regulating gas-liquid flow or pressure to satisfy the demand is used required.

The technological scheme that its technical problem that solves the utility model adopts is: the throttling type solenoid valve comprises valve body, valve pocket, valve port and valve gap, and described valve gap is connected with electromagnetic coil, and described electromagnetic coil center tool moves iron core; Described moving iron core upper end is provided with spring, and the lower end is provided with sealing gasket; Described sealing gasket be positioned at described valve port directly over; The lower end mouth of described valve port is provided with throttling rod, and described throttling rod and described valve body are connected to a fixed.

The shank tail end tool screw thread of described throttling rod spins mutually with described valve body; Described throttling rod upper end tool taper type strangling head.

The peripheral wall of described throttling rod shank is embedded seal ring.

The utility model throttling type solenoid valve product is provided with the throttling rod that spins mutually with described valve body in the lower end mouth of described valve port; By the turn throttling rod, the taper type strangling head of its upper end is approached or away from the passage of valve port, thereby realize changing the function of flow through described valve port gas-liquid flow or pressure.The throttling rod of this product is located in the valve body drain pan, neither increase the overall volume of product, also can reduce the valve body raw materials consumption, be more conducive to the throttle operation in the gas-liquid systems application process, so be widely used in needing often to regulate the gas-liquid control system of flow or pressure.

Description of drawings

Fig. 1 is the structural representation of existing general solenoid valve product.

Fig. 2 is the utility model product structure schematic representation.

Embodiment

As shown in Figure 2, the utility model throttling type solenoid valve comprises valve body 1, valve pocket 9, valve port 8 and valve gap 4, and described valve body 1 two ends are provided with import 3 and outlet 2, and described valve gap 4 is connected with electromagnetic coil 5, and described electromagnetic coil 5 center tools move iron core 6; Described moving iron core 6 upper ends are provided with spring 7, and the lower end is provided with sealing gasket 10; Described sealing gasket 11 be positioned at described valve port 8 directly over; The lower end mouth of described valve port 8 is provided with throttling rod 11, described throttling rod 11 upper end tool taper type strangling heads 12, and the shank tail end tool screw thread of described throttling rod 11 spins mutually with described valve body 1; The peripheral wall of described throttling rod 11 shanks is embedded seal ring 13.

Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.Be illustrated in figure 2 as the structural representation of off-position, described moving iron core 6 is subjected to the effect of spring 7, and the sealing gasket 10 of its lower end is closed valve port 8.After electromagnetic coil 5 energising, described moving iron core 6 overcomes spring 7 resistances and moves in the lump together with sealing gasket 10 and open valve port 8, and import 3 passages and outlet 2 passages are through the valve pocket 9 of valve port 8 tops and conducting.When needs are regulated gas-liquid flow or pressure, then only need the described throttling rod 11 of turn, the taper type strangling head 12 of its upper end is approached or away from the passage of valve port 8, thereby realize changing function by described valve port 8 gas-liquid flows or pressure.The throttling rod 11 of this product is located at valve body 1 drain pan, and the profile compact both can reduce the cost of raw material of valve body 1, also was beneficial to the throttle operation in the gas-liquid systems application process.
