Abstract
The utility model belongs to a liquefied gas pressure-regulating valve. The liquefied gas pressure-regulating valve forms a cylindrical shape, wherein, one end of the liquefied gas pressure-regulating valve is a liquefied gas pot connection end, the other end of the liquefied gas pressure-regulating valve is a combustion stove plate connection end, and the middle of the liquefied gas pressure-regulating valve is a hollow cavity which is arranged inside a conic piston. The lower side of the piston is provided with a spring whose lower side is a block regulating thread; since a movable plug in the hollow cavity can be pushed by the pressure in the cavity of the pressure-regulating valve to control the size of the gas outlet, the liquefied gas pressure-regulating valve effectively achieves the automatic regulation of the gas pressure; the liquefied gas pressure-regulating valve has the advantages of simple structure, long lifespan of the metallic elements, good sealing performance and safe work for long-term use.
Description
The utility model belongs to a kind of liquid gas storage tank pressure regulator valve.
The liquid gas storage tank pressure regulator valve is a pressure lever type at present, its structure is that rubber membrane is housed in the middle of valve body, be equipped with the collar in the middle of the film, the collar is enclosed within an end of depression bar, the other end is that air intake opening stops up, because the air inflow size determines the flexible of rubber membrane, because rubber membrane is flexible, decide what of liquefied gas air intake opening air inflow by intermediate collar and depression bar, realized the automatic adjusting of high voltage variable low pressure automatically.The advantage of this device be simple in structure, pressure regulation is flexible, it is also more stable to change its terminal air pressure at former end high pressure, its weak point is to be rubber membrane in the middle of the valve body, easily aged deterioration, the life-span is short, and valve body is a disc in addition, poor sealing performance needs frequent maintenance just can use.
For solving the deficiency of above pressure controlling of liquefied gas valve, the purpose of this utility model provides a kind of piston-type hydro gasification pressure regulator valve, valve body is cylindrical, and the piston in the middle of utilizing moves the purpose that reaches automatic Regulation, has effectively solved deficiencies such as short, poorly sealed and tempering burning of life-span.
Structural design of the present utility model is achieved in that the piston type pressure regulator valve is cylindrical, form by three parts, the one end is and the liquid gas storage tank link, the other end is for using sebific duct and burning stone or metal plate for standing a stove on as a precaution against fire link, the centre is a pressure regulator valve, it is the core of this device, pressure regulator valve is a metal circular tube, and end cover internal thread joins with the external thread of liquid gas storage tank link, the centre is a cavity, the tapered cylinder piston is housed in the cavity, and piston is taper, three evenly have three forward grooves, have a lateral trench below, it below the groove step, the piston cone point is with rubber seal ring facing to liquid gas storage tank link air inlet circular hole on the piston tail end step, is volute spring near tail end, plug wire is housed below the spring, piston can move forward and backward together with sealing ring in cavity, and the outer screw thread of plug wire can be regulated front and back in cavity, is venthole in the middle of the plug wire, pressure regulator valve is terminal for using sebific duct and burning stone or metal plate for standing a stove on as a precaution against fire link, and pressure regulator valve first and last end is all modular connection.
Its principle of work: when pressure regulator liquid gas storage tank link is connected with liquid gas storage tank, the external thread and the liquid gas storage tank of handwheel are tightened, open air release, liquefied gas extrudes from the gas outlet, pipe end of liquid gas storage tank link, liquefied gas is from piston forward groove on every side, enter the pressure regulator middle cavity through the rubber seal ring outside, cavity fills up the back and discharges from the small-sized circular hole in the middle of the plug wire, when the cavity internal pressure strengthens, squeezing the outwards mobile awl point that makes of piston compresses with the gas outlet, the minimizing of giving vent to anger, root falls in cavity pressure, because gas outlet pressure ambassador piston moves inwards, avoided the tempering generation simultaneously, like this because the front and back minute movement of piston makes the pressure in the cavity keep constant substantially, because of regulating before and after the plug wire, by the pressure size in the spring scalable cavity.Realized the automatic Regulation of liquid gas storage tank.
The utility model has following advantage compared with the prior art, and simple in structure, hardware, long, good seal performance of life-span can prevent tempering, and long-term the use is safe and reliable.
Detailed structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a piston-type hydro gasification pressure regulator valve shape assumption diagram;
Fig. 2 is a piston-type hydro gasification pressure regulator valve structure principle chart.
Its structure is by shown in Figure 2, pressure regulator valve is made up of three parts, (2) be and the liquid gas storage tank link, with the liquid gas storage tank link rubber washer (1) is housed, the centre is rotary handle (3), handle has external thread on (3), dock with liquid gas storage tank, the other end is an external thread, is connected with middle pressure regulator valve (5), and middle (4) are rubber seal, pressure regulator valve (5) is a valve body, piston (6) being housed in the middle cavity, spring (7) is housed below, is plug wire (8) with the corresponding end of spring (7), front end is gas outlet joint (10), the centre is added with rubber seal (9), and tapered piston (6) has the following lateral trench (12) of three grooves (11), is with O-ring seal (13) on the step, whole device is one cylindrical, directly is connected between liquid gas storage tank and the furnace gas dish.
