Abstract
The utility model relates to a valve, in particular to a discharging valve device that is characterized in including a gasket seat 1, a sealing rubber pad 2, a pressing piece 3, a repositioning spring 4, a valve body 5, a connecting rod 6 and a ring washer 7; wherein, one end of the connecting rod 6 is provided with a screw thread that is firmly screwed on the gasket seat 1 and fixes the rubber pad 2 on the gasket seat 1 through the pressing piece 3 to form a valve core; the other end of the connecting rod 6 is provided with a groove; the ring washer 7 is arranged on the groove; the repositioning spring 4 is through the connecting rod 6; a space L is arranged between the valve body 5 and the sealing rubber pad 2; and an angle Alpha is formed between the valve body 5 and the sealing rubber pad 2. The space L between the valve body 5 and the sealing rubber pad 2 is from 1mm to 1.5 mm, and the angle Alphas between the valve body 5 and the sealing rubber pad is 90 degrees to 100 degrees.
Description
The utility model relates to valve, is specially a kind of Drainage valve device.
At present, in Drainage valve, can exhausting air under the system low-voltage state, and under high pressure shutoff gas does not also have.
The purpose of this utility model is to provide the Drainage valve device of a kind of simple in structure, with low cost, easy for operation, ventilation, good sealing effect.
The purpose of this utility model is achieved in that it is by gasket base (1), sealing rubber pad (2), compressing tablet (3), Returnning spring (4), valve body (5), connecting rod (6), ring washer (7) constitutes, one end of connecting rod (6) has screw thread to be tightened on gasket base (1) and by compressing tablet (3) sealing rubber pad (2) is fixed on upward composition spool of sealing seat (1), the other end of connecting rod (6) is fluted, ring washer (7) is on its groove, Returnning spring (4) is through on the connecting rod (6), gapped L between valve body (5) and the sealing rubber pad (2) has α degree angle between valve body (5) and the sealing rubber pad (2).L between valve body (5) and the sealing rubber pad (2) is 1mm-1.5mm, and α is the 90-100 degree between valve body (5) and the sealing rubber pad (2).
Advantage of the present utility model is: exhausting air, high pressure lower seal gas shutoff body under the low-pressure state, simple in structure, with low cost, volume is little, in light weight.
Fig. 1 is the utility model structural principle schematic representation.
Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail: it is by gasket base (1), sealing rubber pad (2), compressing tablet (3), Returnning spring (4), valve body (5), connecting rod (6), ring washer (7) constitutes, one end of connecting rod (6) has screw thread to be tightened on gasket base (1) and by compressing tablet (3) sealing rubber pad (2) is fixed on upward composition spool of sealing seat (1), the other end of connecting rod (6) is fluted, ring washer (7) is on its groove, Returnning spring (4) is through on the connecting rod (6), gapped L between valve body (5) and the sealing rubber pad (2) has α degree angle between valve body (5) and the sealing rubber pad (2).L between valve body (5) and the sealing rubber pad (2) is 1mm-1.5mm, and α is the 90-100 degree between valve body (5) and the sealing rubber pad (2).Working procedure is: under the conventional state, Returnning spring backs down the caulking gum rubber cushion in the spool, has formed the space with the α degree conical surface of valve body.The taper pipe thread of valve body lower portion links to each other with system in the use, when the source of compressed air in the system had small leakage, its gas will emit along gap, the vent (8) of the gap L between low pressure drain valve body and the sealing rubber pad, conical surface, connecting rod and valve body.Can not become permanent savings gas, make and produce pressure in the system pipeline.Source of the gas in system is opened, when the pressure of whole system raises suddenly, pressure in the system will overcome Returnning spring and try hard to recommend movable valve plug and move forward, be close to the conical surface of valve body, valve body and sealing rubber pad form closed state, the air cavity of valve body lower portion can not communicate with the vent (8) on valve body top, and pressurized air just can not overflow.The system that reached can exhausting air under low-pressure state, and the effect of shutoff gas under high pressure.
Claims (2)
1, a kind of Drainage valve device, it is characterized in that: it is by gasket base (1), sealing rubber pad (2), compressing tablet (3), Returnning spring (4), valve body (5), connecting rod (6), ring washer (7) constitutes, one end of connecting rod (6) has screw thread to be tightened on gasket base (1) and by compressing tablet (3) sealing rubber pad (2) is fixed on upward composition spool of sealing seat (1), the other end of connecting rod (6) is fluted, ring washer (7) is on its groove, Returnning spring (4) is through on the connecting rod (6), gapped L between valve body (5) and the sealing rubber pad (2) has α degree angle between valve body (5) and the sealing rubber pad (2).
2, according to claim 1 described a kind of Drainage valve device, it is characterized in that: the L between valve body (5) and the sealing rubber pad (2) is 1mm-1.5mm, and α is the 90-100 degree between valve body (5) and the sealing rubber pad (2).
