The utility model provides a technical scheme has that structural design is equitable, the design is ingenious, the requirement of rapid switching under can the be really great pressure difference.
Description
Art
This utility model relates to a kind of valve, particularly a kind of pressure-control valve.
Background technology
Existing pressure-control valve is primarily used to meet the requirement of power or the moment that actuator is proposed. Including relief valve, overflow valve, air relief valve and sequence valve. But more special system is required for Stress control, as for a certain pressure system, need to realize rapid opening and closing when intrasystem pressure reaches the upper and lower bound of regulation, and the difference of pressure upper and lower limit is very big in system, opening/closing time requirement is short, operating frequency is high, and these requirements then cannot realize for existing pressure-control valve.
Summary of the invention
The purpose of this utility model is to provide a kind of when the upper and lower bound pressure of regulation, a kind of pressure-control valve that can open and close rapidly.
The technical solution of the utility model is: a kind of pressure-control valve, including valve body and the spool being arranged in valve body, it is characterized in that the above-mentioned through hole having on spool and being perpendicular to valve core axis, on the valve body of pressure-control valve open position, two holes are had with the through hole correspondence position on spool, pressure transmission hole is had in a side end face of valve body, one end of pressure transmission pipe is connected with pressure transmission hole, the other end and vaporization chamber inner chamber UNICOM, be provided with back-moving spring in the valve body of the spool other end and pressure adjusts bolt.
It is provided with on above-mentioned valve body and adjusts the damping unit that spool moves, this damping unit is by being arranged between spool with back-moving spring with spool to match the spheroid contacted and the stage clip for spheroid presses to spool face forms, and spool and spheroid contact portion are spheroid or cone.
The valve body of above-mentioned stage clip one end is provided with adjustment bolt.
Above-mentioned damping unit is made up of the two set damping units being symmetrically mounted on spool both sides.
The technical scheme that this utility model provides has reasonable in design, is skillfully constructed, can the requirement of opening and closing rapidly under really bigger pressure difference value.
The technical solution of the utility model is the pressure in the vaporization chamber controlled will to be needed to be directly passed to spool by pressure transmission pipe, promoting spool to move makes pressure-control valve open, when evaporate room pressure less than valve body in the pressure of back-moving spring time, spool moves rapidly under the effect of the spring force of back-moving spring, is closed by pressure-control valve. For ensureing that the technical program works under bigger pressure difference value, valve body is mounted with damping unit, can fully ensure that this device can work under bigger pressure difference value on the one hand, this device can be made can to realize high-frequency rapid opening and closing on the other hand.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, be provided with nozzle 6 in the upper end of vaporization chamber 1, this pressure-control valve is arranged on nozzle, controls the opening and closing that the gases at high pressure in vaporization chamber are sprayed by nozzle. Vaporization chamber is considered as the pressure system used by this pressure-control valve, and this intrasystem pressure is step, altofrequency height change.
Upper and lower holes on valve body 4 is managed up and down with nozzle respectively and is connected, spool 5 has the through hole 3 being perpendicular to valve core axis, pressure transmission pore pressure power is had in valve body right side, the upper end of transmission pipe 2 is connected with pressure transmission hole, lower end and the inner chamber UNICOM of vaporization chamber 1, be provided with back-moving spring 9 in the valve body of spool left end and pressure adjust bolt 10. For ensureing that this device can in bigger pressure difference value and high-frequency rapid opening and closing, the valve body of above-mentioned pressure-control valve is provided with adjustment spool move and control the damping unit of pressure, this damping unit is by being arranged between spool with back-moving spring with spool to match the spheroid 8 contacted and the stage clip 7 for spheroid presses to spool face forms, and spool and spheroid contact portion are spheroid or cone. The spring thrust overcoming stage clip 7 to pass through the spheroid 8 pressure to spool left end spheroid or cone and back-moving spring is so needed when spool is moved to the left.
During work, when the pressure in vaporization chamber increases rapidly, pressure in vaporization chamber passes through pressure transmission pipe by pressure transmission to the spool right side in pressure-control valve, when the pressure of spool right-hand member is more than the spring force of damping unit and back-moving spring, spool is promoted rapidly to be moved to the left, when the through hole on spool move to two the hole correspondence positions up and down on valve body after, gases at high pressure in vaporization chamber are sprayed by nozzle, the pressure in vaporization chamber is made sharply to decline, under the spring-force driven dual of back-moving spring, spool moves right two bore closures up and down on valve body rapidly.
The pressure of pressure-control valve is to adjust bolt 10 by rotational pressure to adjust pressure size with adjusting bolt 11. For ensureing service life and the sensitivity of this device, damping unit is to be symmetrically mounted on spool both sides by two.
