Abstract
The utility model provides an electromagnetic valve for a pulse generator. The electromagnetic valve for the pulse generator is composed of a static iron core, a coil, a movable iron core, screws, an energy storage device, a reset spring, a stroke adjusting device and a valve head. The static iron core is in threaded connection with the energy storage device. The coil is wound around the outer face of the movable iron core. The movable iron core, the stroke adjusting device and the valve head are connected through the screws. The energy storage device and the stroke adjusting device are sleeved with the reset spring. According to the difference of impact or residual magnetism of the movable iron core, the energy storage device is replaced. The distance between the stroke adjusting device and the energy storage device is adjustable. Abrasion to the movable iron core and the static iron core is reduced, the movable iron core is rapidly separated from the static iron core, pressure signal change of the ground is obvious, and the trailing phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of pulse oscillator solenoid valve, particularly oil, gas drilling is measured with pulse generation solenoid valve.
Background technique
At present, in oil drilling measuring equipment, in underground equipment, pulse signal generator is that the data transfer of underground survey is become to pulse signal, and by the solenoid valve transmitted signal on its pulser, to ground acquisition equipment, ground installation converts survey data again to.Solenoid valve transmitted signal is mainly the break-make of utilizing solenoid valve, drives the pull-up of valve head to put down, and ground hydrodynamic pressure is changed, thereby underground signal is passed to ground.During existing solenoid valve adhesive, moving iron core and static iron core impact force are large, cause moving iron core and static iron core serious wear; When solenoid valve is thrown off, because iron core exists remanent magnetism phenomenon, disengage speed is excessively slow, causes ground signal to change not obvious, occurs conditions of streaking.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides pulse oscillator solenoid valve, to solve the aforementioned problems in the prior.
The technological scheme that the utility model adopts is: pulse oscillator is comprised of static iron core, coil, moving iron core, screw rod, energy storage device, returning spring, adjusting device for travel, valve head with solenoid valve, wherein static iron core is threaded with energy storage device, coil is around moving iron core outside, moving iron core, adjusting device for travel, valve head connect by screw rod, and returning spring is enclosed within on energy storage device and adjusting device for travel.Different according to moving iron core impact force or remanent magnetism, change energy storage device.The distance of adjusting device for travel and energy storage device is adjustable.At moving iron core and static iron core adhesive last section stroke, adjusting device for travel contact energy storage device also does work to it, and iron core and static iron core impact force are obviously reduced, and reduces moving iron core and static iron core wearing and tearing; When moving iron core and static iron core will be thrown off, energy storage device releases energy to moving iron core acting, and disengage speed is accelerated, and ground signal changes obviously, without conditions of streaking.
The beneficial effects of the utility model are: reduce moving iron core and static iron core wearing and tearing, moving iron core and static iron core disengage speed are fast, and ground pressure signal intensity is obvious, without conditions of streaking.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model sectional view.
1. static iron cores in figure, 2. coil, 3. moving iron core, 4. screw rod, 5. energy storage device, 6. returning spring, 7. adjusting device for travel, 8. valve head.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, pulse oscillator is comprised of static iron core (1), coil (2), moving iron core (3), screw rod (4), energy storage device (5), returning spring (6), adjusting device for travel (7), valve head (8) with solenoid valve, wherein static iron core (1) is threaded with energy storage device (5), coil (2) is around moving iron core (3) outside, moving iron core (3), adjusting device for travel (7), valve head (8) connect by screw rod (4), and returning spring (6) is enclosed within on energy storage device (5) and adjusting device for travel (7).Different according to moving iron core (3) impact force or remanent magnetism, change energy storage device (5).Adjusting device for travel (7) is adjustable with the distance of energy storage device (5).During coil (2) energising, moving iron core (3) and static iron core (1) adhesive, static iron core (3) drives screw rod (4) adjusting device for travel (7) and valve head (8), and compression reaction spring (6).In the final stage of attracting process, form regulating device (7) contact energy storage device (5), and to its acting, reduce moving iron core (3) speed, reduce the impact force of moving iron core (3) and static iron core (1), thereby reduce moving iron core and static iron core wearing and tearing; During coil (2) power-off, moving iron core (3) and static iron core (1) are thrown off, and energy storage device (5), to static iron core acting, makes static iron core Quick release, and ground pressure signal intensity is obvious, without conditions of streaking.Form regulating device (7) and can adjust upper-lower position, thereby change energy storage device (5) effect stroke.
Above the utility model embodiment is described in detail, and set forth embodiment, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as the restriction that the utility model is used.
