Abstract

The utility model discloses a plunger type electromagnetic valve. Two sides of a valve body 7 are provided with air inlet holes 13, and a valve core 6 can move inside the valve body 7 by screw rods 4 under mutual actions of two magnetic blocks 8 and 9, realizing the opening and closing of gas circuits. The utility model has the advantages of good sealing properties, easy opening and closing under higher pressure, separated electricity and the gas circuits, and safety. The utility model is suitable for controlling various inflammable and poisonous gas with lower pressure.

Description

The plunger type solenoid valve
The utility model relates to a kind of plunger type solenoid valve, is to be used for the control gear of switch gas meter gas circuit for various controllable type gas meters are supporting.
Because pipeline gas users' such as rock gas, coal gas growth year by year in the city is carried out scientific management to combustion gas, use the controllable type gas meter imperative, and these gas meters all must possess the controller that can open or close gas circuit---solenoid valve.Though Chinese patent discloses several solenoid valves, can satisfy the requirement that opens or closes gas circuit, but exist that valve seal is tight, energy consumption is big, the hydrodynamic pressure loss is big, switch valve deficiencies such as relatively higher, the anti-negative pressure ability of negative pressure that produces in igniting or when flame-out of difficulty, user is more weak under elevated pressures.
The purpose of this utility model is exactly the deficiency that exists in the above-mentioned background technology in order to overcome, and provide that a kind of energy consumption is little, good seal, fluid crushing are little, more convenient, the plunger type solenoid valve with anti-negative pressure ability of switch valve under the supply gas pressure.
The purpose of this utility model realizes by following technical solution: this plunger valve comprises a motor, in valve body, be provided with a valve body with inlet hole and air outlet hole, screw rod rotates in spool by swivel nut, cause spool to move radially, magnetic patch in the valve casing external shielding layer is connected with motor shaft, and corresponding with the magnetic patch of valve casing inner screw termination.Leave the gap between the both sides of valve body and the valve casing inwall, inlet hole is positioned at the both sides of valve body, and air outlet hole is positioned at the valve body bottom.
Fig. 1: overall structure schematic representation of the present utility model.
The A-A sectional view of Fig. 2: Fig. 1.
The B-B sectional view of Fig. 3: Fig. 2.
As shown in Figure 1, the bilateral symmetry of the valve body 7 in valve casing 1 is provided with inlet hole 13, and the bottom of valve body 7 also has air outlet hole 14.This valve body 7 has between the inwall of the both sides of inlet hole 13 and valve casing 1 and leaves the gap (referring to Fig. 2) that air communication is crossed.The spool 6 that is arranged in valve body 7 and valve body 7 inwalls are located (referring to Fig. 3) by feather key and keyway 15 for being slidingly matched between the two, and spool 6 can not be rotated.One end of the screw rod of installing with valve body 7 and spool 6 coaxial lines 4 is embedded in the lasso 3, and its other end headband has magnetic patch 8, is connected by swivel nut 5 between screw rod 4 and the spool 6.For preventing the interference of external magnetic field to this solenoid valve, on valve casing 1 outer wall, be provided with the screen layer of making by permeability magnetic material 2,12, wherein screen layer 12 is a hollow body, the double support of making motor 11, an end of motor shaft is by the magnetic patch 9 of the opposite setting of magnetic patch 8 polarity in axle sleeve 10 fixedly connected one and the spool 6 in this screen layer 12.Under 7 valve casing 1 be by making as nonmagnetic substances such as copper, aluminium, it is connected between gas meter and the steam line, and valve body 7 is positioned at valve casing 1 inner chamber.
The working procedure of this solenoid valve is such: when motor 11 rotated, the magnetic patch 9 that is connected as a single entity with its axle sleeve 10 rotated by magnetic patch 8 and the screw rod 4 that the action of a magnetic field drive is positioned at spool 6 thereupon.Because the effect of installation swivel nut 5 and keyway 15 between spool 6 and screw rod 4, spool 6 vertically moves in valve body 7, thereby can realize the unlatching of inlet hole 13 and air outlet hole 14 or close.During two end positions in spool 6 moves to valve body 7, the moment of motor 11 is greater than the moment in magnetic field between two magnetic patch, and two magnetic patch 8,9 just produce and skid relatively, can not cause any infringement to motor 11.Also, can't produce misoperation, increase the reliability and the anti-negative pressure ability of this valve because of valve casing 1 internal air pressure too high (or negative pressure height) makes spool 6 because the moving direction and the airflow direction of spool 6 are orthogonal.Being symmetrical arranged of two inlet holes 13 makes the make a concerted effort minimum of air inlet to spool 6 pressure on the valve body 7, and minimum degree is reduced in the friction between spool 6 and the valve body 7, and the phenomenon that can not leak air, and has also reduced the energy consumption of motor 11 simultaneously.
Structure of the present utility model is comparatively simple, and electricity and gas two-part are isolated, and can therefore not produce contingency.The structural design of this valve has good seal performance, and under high pressure the open and close valve all is easier to, and anti-negative pressure ability is stronger, and its screen layer also can prevent the advantages such as interference of external magnetic field, is applicable to that various low pressure are inflammable, the control of poisonous gas circuit.
