Abstract

The utility model relates to an electromagnetic valve for braking speed regulator, which is characterized in that the upper end or the lower end of a casing is provided with a guide lengthening joint 10 which can make a movable iron core move up and down in the casing; the combined length of the movable iron core and a fixed iron core is greater than or equal to the length of a coil; a push rod 8 or a guide rod 13 is provided with an initial zero adjustment screw of the movable iron core. The utility model can enhance the electromagnetic attraction, decrease magnetic loss, and reduce exciting electric power so as to reach the goal of power saving. The utility model is suitable for being served as the braking electromagnetic valve of the speed regulator of the internal-combustion engine.

Description

Speed regulator parking solenoid valve

The utility model relates to solenoid valve, particularly a kind of internal-combustion engine parking solenoid valve of hydrodynamic governor.

Existing hydrodynamic governor parking electromagnetic valve device has the shelves lid that the moving iron core of restriction moves upward, for guaranteeing that the electromagnetic attraction that produces behind the coil electricity makes iron core to the static iron core adhesive, this grade lid is to be made by non-magnet material, and be the flange dish type, be connected with housing with screw near coil, the working stroke distance that is occurred when cooperating with multiple speed regulator in such apparatus structure is not enough, the moving iron core that inserts in the coil must correspondingly be done shortlyer, owing to this reason, when coil is not switched on, space length between moving iron core and the static iron core, must become length fixes, uncontrollable magnetic circuit working gas gap, in addition since shelves lids every magnetic core, static iron core, form the very big non-working-gap of length in the magnetic circuit that housing constitutes, because the existence of these two kinds of bigger magnetic air gaps certainly will cause great magnetic to move heat loss, in order to obtain enough electromagnetic attractions, therefore need to increase excitatory electric power, thereby also just increased the consumption of electric energy.

The purpose of this utility model is to improve the above-mentioned shortcoming of existing hydrodynamic governor parking electromagnetic valve device and a kind of improved power consumption energy-saving hydraulic speed regulator parking solenoid valve little, rational in infrastructure that has is provided.

The novel above-mentioned purpose of this reality realizes by such technological scheme: i.e. this speed governing parking solenoid valve by coil, be enclosed within the outer housing of coil, the static iron core of fixedlying connected with housing, insert the moving electric core in the coil, moving iron core upper end connect by guide rod and the push rod of lower end form; Wherein the braking of guide rod and hand is lifted head and is connected; It is characterized in that: in the upper end of housing or the lower end have can make iron core within it one, the guiding lengthening joint that moves down, the end of this guiding lengthening joint has every the magnetic door; The composition length of moving iron core and static iron core is more than or equal to stitch length; Has the initial zero-bit controlling mechanism of the moving iron core that constitutes by adjusting nut on the push rod or on the guide rod.

Said structure of the present utility model can further specify by three embodiments that accompanying drawing provides.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the utility model embodiment 1 a structure cut-away view;

Accompanying drawing 2 is the utility model embodiment 2 a structure cut-away view;

Accompanying drawing 3 is the utility model embodiment 3 a structure cut-away view.

Referring to accompanying drawing: among the figure: head is lifted in the braking of 1-hand, the 2-Returnning spring, and 3-is every magnetic shelves lid, and 4-moves iron core, 5-coil, 6-housing, 7-static iron core, 8-push rod, 9-base plate, the 10-lengthening joint that leads, 11-adjusting nut, 12-transiting rod, 13-guide rod.

Referring to Fig. 1. in the present embodiment, guiding lengthening joint 10 is threaded with housing 6, and push rod 8 ends are connected with transiting rod, and the flexible transiting rod of adjusting can change push rod length, has Returnning spring 2 at guide rod and between magnetic shelves lid.Embodiment is energising parking formula solenoid valve.

Referring to Fig. 2, in the present embodiment, has Returnning spring 2 at guide rod and between the magnetic door, guiding lengthening joint 10 and housing 6 expanded joints; Be threaded with guiding lengthening joint 10 every magnetic shelves lid 3, regulate every the magnetic door, can realize the adjusting of the moving initial zero-bit of iron core, the adjusting nut on push rod 8 can be realized this adjusting too.This embodiment is energising parking formula solenoid valve.

Referring to Fig. 3.In this embodiment, the guiding lengthening joint be positioned at housing the lower end and with the housing expanded joint, the position of dynamic and static iron core is upper and lower switches, and has adjusting nut on guide rod 13, can carry out the adjusting of the initial zero-bit of iron core; Push rod 8 is supported by Returnning spring.This embodiment is outage parking formula solenoid valve.

Guiding lengthening joint 10 in the above-described embodiments adopts permeability magnetic material to make, and adopts non-magnet materials such as aluminium or copper to make every the magnetic baffle plate.

This reality is novel owing to said structure has obtained significant technique effect: at first, owing to increased the guiding lengthening joint, increased the length of moving iron core, thereby greatly reduced or eliminated non-working-gap in the magnetic circuit; Owing to increased the initial zero-bit controlling mechanism of moving iron core, can require and as far as possible the magnetic circuit working gas gap is adjusted to minimum according to the cooperation of motor under braking state, two lift and reduced magnetomotive consumption effectively thus, excitatory power is descended, power consumption reduces, thereby reaches the purpose of economize on electricity.

The utility model is fit to do the parking solenoid valve of speed governor of internal-combustion engine.
