Abstract

The utility model relates to a close plastic electromagnetic valve with external source nipples at both ends, which can be installed at the end of a fluid pipeline, can be also installed at the middle segment of the pipeline, and can be used for automatically controlling the pipeline. The utility model overcomes the disadvantages that the existing plastic electromagnetic valve can not be installed at the middle segment of the pipeline, and a body on the valve is exposed. The utility model is that both sides of a valve body 11 are respectively provided with a segment of hexagon F of a clamping wrench. The external ends of the valve body are external source nipples B and D, and a valve hood 13 is clamped on the valve body 11 to close down the body on the valve. The utility model has close performance, and the utility model can accomplish that the utility model can be installed at the middle segment of the pipeline and automatically controls the pipeline. Therefore, the utility model can be widely used in the fluid pipeline.

Description

Closed two ends outside thread interface plastics solenoid valve

The utility model relate to a kind of not only can be contained in the fluid circuit terminal but also can be contained in the pipeline stage casing pipeline is implemented the closed two ends outside thread interface plastics solenoid valve of control automatically.

Existing plastics solenoid valve is contained in the electromagnet on the valve body mainly by valve body, is provided with the spool that is used for controlling the open and close through flow hole in electromagnet core portion, and the through hole lid and the elastomer diaphragm that are contained under the spool are formed, and spool is by magnet control.The shortcoming of this solenoid valve is: the valve upper body exposes in the environment that uses, wiring terminal corrosion-vulnerable and clashing and breaking; The inlet end of valve is the outside thread interface, and water outlet end then is threadless round shape pipe, can not proceed the scyewed joint of sealing again with pipeline.Therefore, it can only be contained in the terminal of pipeline, and control is automatically implemented to pipeline in the stage casing that can not be contained in pipeline.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of terminal that both can be contained in pipeline can be contained in automatic control is implemented in the pipeline stage casing to pipeline closed two ends outside thread interface plastics solenoid valve.

The technical solution that the utility model is taked is, closed two ends spiral shell outside thread interface plastics solenoid valve by valve body, be contained in valve body electromagnet, be contained in spool and spring in the electromagnet inner chamber, be contained in through hole lid under the spool and elastomer diaphragm and valve bonnet and form, there is interface at the valve body two ends, there are two valve pockets to communicate with two interfaces respectively, two valve pockets are lived by elastomer diaphragm and through hole cap seal at the top, spool is pressed on the through hole lid flow-out hole, it is characterized in that: respectively there are six sides of one section clamp hand the valve body both sides, and its outer end is the outside thread interface; Valve bonnet is installed on the valve body, and the valve upper body is sealed.

The utility model has encapsulation compared to existing technology, can be contained in the stage casing of pipeline, and is easy for installation, and sealing is reliable; Processability of product structure is good, easy processing.

The utility model will be described in further detail in conjunction with the accompanying drawings.

Fig. 1 is closed two ends outside thread interface plastics electromagnetic valve structure figure.

Fig. 2 is the A-A sectional drawing among Fig. 1.

Fig. 3 is the top view of Fig. 1.

In Fig. 1, load onto electromagnet with screw 10 on plastics valve body 11, the constituting of electromagnet: be wound with coil 8 on the valve upper body 4, valve upper body 4 is made of plastics, and magnet case 3 and last magnet case 6 are housed down in it, and upper and lower magnet case all is a cylindrical shell annular shape; Valve upper body 4 also is equipped with two wiring terminals 12, and wiring terminal connects with coil 8 by lead; Magnetic conducting plate 5 tops are sleeved on the magnet case 6, and the bottom is plugged on valve upper body 4 and the following magnet case 3.Three screws 10 of valve upper body 4 usefulness are contained in (referring to Fig. 3) on the valve body 11.Valve upper body inside is hollow, a spring 7 is housed in hollow, and spring bottom is a spool 9, spool 9 is pressed on the through hole N of through hole lid 2, valve pocket E in through hole N and the valve body 11 communicates, and through hole lid 2 is placed on the elastomer diaphragm 1, and elastomer diaphragm is contained between valve upper body 4 valve bodies 11.Also have a through hole H on the through hole lid 2, this through hole is communicated with the valve pocket C in the valve body with the cavity M of valve upper body.The six side F that one section clamp hand is respectively arranged in the valve body both sides, its outer end is outside thread interface B, D, and threaded coupling B communicates with valve pocket C, and threaded coupling D communicates with valve pocket E, and valve bonnet 13 is installed on the valve body 11, with 4 sealings of valve upper body.

The working procedure of closed two ends outside thread interface plastics solenoid valve shown in Figure 1 is: when fluid enters the C chamber from threaded coupling B, enter the M chamber through through flow hole H, because spool is closed through flow hole N, make fluid can not enter the E chamber, solenoid valve is in closed condition.When the connection power supply, work of electromagnet, spool 9 moves upward under the effect of electromagnetic force, opens through flow hole N, and fluid enters the E chamber, enters the hypomere pipeline through threaded coupling D, at this moment, the state that solenoid valve is out.After cutting off the electricity supply, spool 9 is closed through flow hole N, and solenoid valve is in state.

Claims

1. closed two ends outside thread interface plastics solenoid valve, it is by valve body 11, be contained in the electromagnet on the valve body 11, be contained in spool 9 and spring 7 in the electromagnet inner chamber, be contained in through hole lid 2 and elastomer diaphragm 1 under the spool, and valve bonnet 13 is formed, there is interface at the valve body two ends, there are two valve pockets (C, E) to communicate with two interfaces respectively, two valve pockets are covered 2 envelope Cui at the top by elastomer diaphragm 1 and through hole, spool 9 is pressed on the flow-out hole N of through hole lid, and it is characterized in that: respectively there are six side F of one section card spanner valve body 11 both sides, and its outer end is outside thread interface B, D; Valve bonnet 13 is installed on the valve body 11, with 4 sealings of valve upper body.
