Abstract
The utility model provides a monitoring-type pressure valve, and relates to the technical field of reducing valves. The monitoring-type pressure valve comprises a valve body, a high-pressure air intake small hole, and a piston, wherein a cone is arranged in the central position at the top of the piston; the bottom diameter of the cone is larger than the pore diameter of the high-pressure air intake small hole; the top end of the cone can extend into the high-pressure air intake small hole; and a pressure sensor is arranged in the valve body. The monitoring-type pressure valve can stabilize and adjust the flow rate of input air, so as to enable the output flow rate to be stable and reliable; and the sensing-type reducing valve also can monitor the air pressure in the valve body, thereby improving the security.
Description
Technical field
The utility model relates to reduction valve.
Background technique
Gas pressure reducer is the throttling by open-shut device, and inlet gas pressure is reduced to the outlet pressure of a certain needs, and makes outlet pressure keep stable equipment.It is connected use with gas cylinder, at first pressurized gas are delivered to decompressor, and high pressure air reducing to the low-pressure gas of required force value, is controlled its gas output flow again.
Existing gas pressure reducer comprises valve body, is provided with the high pressure admission aperture in the valve body, opens and closes the high pressure admission aperture by piston, and gas has just entered low-pressure cavity after the high pressure admission aperture comes out.During use, when the pressurized gas promotion piston of turning right, piston is opened in a flash, and the flow area of high pressure admission aperture just increases severely to maximum, and it is maximum that flow also reaches.After low-pressure cavity reaches certain pressure, piston is pushed to the left side, close the valve port of high pressure admission aperture, at this moment flow reaches minimum.Such structure causes the instability of flow by the input of high pressure admission aperture, causes the instability of flow of output.
The model utility content
In order to address the above problem, the utility model provides a kind of band monitor-type pressure valve, and this band monitor-type pressure valve can stable regulation for the gas flow of input, and then makes output flow reliable and stable, and can monitor the valve body internal pressure, improves Security.
The utility model adopts following technological scheme, a kind of band monitor-type pressure valve, comprise valve body, high pressure admission aperture, piston, the top center position of described piston is provided with a cone, the footpath, the end of cone is greater than the high pressure admission small aperture, described cone top can be stretched in the high pressure admission aperture, is provided with pressure transducer in the valve body.
The beneficial effects of the utility model are, owing to adopt said structure, this reduction valve can stable regulation for the gas flow of input, and then makes output flow reliable and stable, and can monitor the valve body internal pressure, improves Security.
Description of drawings
Fig. 1 is the structural representation of band monitor-type pressure valve of the present utility model.
Embodiment
As shown in Figure 1, a kind of band monitor-type pressure valve, comprise valve body 1, high pressure admission aperture 2, piston 3, the top center position of described piston 3 is provided with a cone 4, the footpath, the end of cone 4 is greater than high pressure admission aperture 2 apertures, described cone 4 tops can be stretched in the high pressure admission aperture 2, are provided with pressure transducer 5 in the valve body 1.Described cone 4 tops can be stretched in the high pressure admission aperture 2, and can move forward and backward to regulate air-flow air inlet area along the little axially bored line of high pressure admission with piston 3.The footpath, the end of above-mentioned oval cone 4 is greater than the high pressure admission small aperture, and the sealing of high pressure admission aperture gas channel relies on fully between cone and the high pressure admission aperture inwall and realizes like this.Owing to be provided with pressure transducer 5 in the valve body 1, be convenient to monitor valve body 1 internal pressure, improve operating security.
Claims (1)
