Abstract
The utility model discloses a combined pressure restricting valve which utilizes the plus-minus of ring weights on a radical valve to comprise an adjustable pressure limiting valve. The utility model is characterized in that the combined pressure restricting valve utilizes the different combinations of the ring weights to obtain different working pressures of the adjusted device between the minimum working pressure established by the radical valve and the maximum pressure capable of being adjusted by the radical valve after adding all the ring weights. The utility model is mainly used for a device using a pressure limiting valve for insurance and sealing, in particular to being suitable for a pressure cooker adjusting and using pressure.
Description
The utility model relates to a kind of pressure-limit valve, is specially adapted to the device that uses the pressure-limit valve sealing, protects limit and pressure regulation.
A lot of devices utilize pressure-limit valve sealing and insurance, and it is that the sealing awl cooperates with the sealing column of operative installations and reaches the purpose of sealing, and the weight of pressure-limit valve self acts on and seals taper and become positive pressure and insure.But some device also needs to regulate working pressure, is exactly like this as pressure cooker, as can not be according to the corresponding working pressure of different food selection, and will be very sorry.
This is suitable for novel purpose and provides a kind of improved combined type pressure-limit valve, can satisfy the requirement of the device that needs sealing, insurance, pressure regulation.
The purpose of this utility model is achieved in that to start with from the weight that changes former pressure-limit valve valve body former pressure-limit valve is divided into basic valve and one group of circle sign indicating number, by the various combination of circle sign indicating number on basic valve, reaches the purpose to device sealing, insurance, pressure regulation.
This is suitable for novel because of only changing the valve weight of former pressure-limit valve, pressure-limit valve working principle before still adopting, and without any change, so this device popularization is easy, applicability is strong to the device that utilizes pressure-limit valve.
Existing this suitable new structure of accompanying drawings and enforcement.
Fig. 1 is the sectional drawing of the utility model combined type pressure-limit valve.
Details and the working condition that is suitable for the concrete device of novel proposition according to this is described below in conjunction with Fig. 1.
This device comprises cover shape base valve (1), sealing awl (4) is equipped with along axial direction in its top, radially all do not have several exhaust ports (5) on base valve (1) sidewall, there is a flange (6) base valve (1) lower end, one group of circle sign indicating number (2) is held by flange (6), sealing awl (4) places on the sealing column (3) of operative installations and finishes sealing, by adding and subtracting the circle sign indicating number (2) that basic valve (1) is gone up, cause different positive pressures to put on the sealing awl (4), when raising, the sealing column internal pressure of operative installations causes when whole pressure-limit valve backed down that unnecessary pressurized gas are overflowed and when exhaust port was discharged, the operative installations internal pressure was set pressure.
Claims (3)
1, a kind of combined type pressure-limit valve, comprise a cover shape base valve (1), upper end edge axial direction at basic valve (1) is equipped with sealing awl (4), the top of base valve one sidewall has several exhaust ports (5) uniformly along warp-wise, it is characterized in that the lower end of basic valve (1) is provided with as on flange (6) the holder sign indicating number frame that holds in the palm the sign indicating number frame one group of circle sign indicating number (2) being housed.
2, pressure-limit valve according to claim 1 is characterized in that basic valve (1) lower end is provided with the flange (6) as holder sign indicating number frame.
3, pressure-limit valve according to claim 1 is characterized in that the circle sign indicating number is one group.
