Abstract
The utility model discloses an automatic control overpressure and ultra-flow fuel gas valve, one end of a fuel gas pipe joint is screwed into a valve body inlet, between two valve seats of a valve body intra-cavity is provided with a ball valve, a valve lever is installed in the upper sleeve, a knob is fixed on the top of the valve lever, a guiding sleeve is installed in the fuel gas pipe joint intra-cavity, the opposite fuel gas pipe joint inlet is provided with a central hole, around the hole and extending to the guiding sleeve near the central hole is provided with an inlet hole; the regulating valve which comprises the pole installed in the ball shell and the ball shell is installed in the guiding sleeve and may slide, the handle end extending out the guiding sleeve is provided with a blocking platform, between the blocking platform and the guiding sleeve separating sleeve is provided with a compression spring. When the supplying gas is overpressure and ultra-flow, the fuel gas pushes the regulating valve into the valve seat hole and plugs up, solves the problem of that the gas transmission hose installed at the end of the valve body is easy to fall off which occurs danger; when the supplying gas is normal, under the function of the spring, the regulating valve moves back, the valve seat is opened, thus plays the function of automatic control, avoids the stopcock rotating fixedly that occurs the control losing problem.
Description
Technical field
The utility model belongs to daily necessities, uses, can realize the super flow of the superpressure gas valve of control automatically on specifically a kind of fuel gas transportation pipeline.
Background technique
The gas valve that is used for gas range of Chu Shouing mostly is stopcock in the market, be that the moving rotation of armrest cock comes the unlatching of control valve or closes, but after long-term the use, make easily and bond together between cock and valve body and can't open, motionless and the out of hand effect of cock rotation, and when air feed went wrong superpressure, super flow, its terminal air hose that connects easily came off, and can cause danger because of cutting off source of the gas automatically.
The model utility content
For the use that makes combustion gas safer, fuel tube is more reliable with valve, the technical solution of the utility model is: an end of gas kitchen pipe joint is screwed into the outlet side of valve body, two valve base chambers of body cavity have spherical valve, in the sleeve on its top valve rod are installed, and knob is fixed on valve rod top, inner chamber at gas kitchen pipe joint, the setting sleeve of opening subtend valve seat is installed, and an end of setting sleeve subtend gas kitchen pipe joint air inlet has center hole, and the nearly center of the sleeve nose end that is extended down to setting sleeve around the hole has inlet hole; The modulating valve that is installed in interior bar of spherical shell and spherical shell composition is slidably mounted in the setting sleeve, and setting sleeve stretches out in its bar portion, and band one retaining platform in top is with pressure spring on the handle between retaining platform and setting sleeve.
Be the angle of swing of control handle, can open a fan-shaped restraining groove on the sleeve on valve body top, position limit pin laterally is fixed on the valve rod by restraining groove.
Because a modulating valve that can slide at setting sleeve is arranged in the setting sleeve that the inner chamber of gas kitchen pipe joint is installed, the shank of modulating valve is with pressure spring, when air feed superpressure, super flow, combustion gas is pushed modulating valve to valve seat orifice by its spherical shell and it is blocked, and has solved the problem that the air hose that is positioned on the valve body end easily comes off and causes danger; When air demand just often, under the effect of spring, withdraw from modulating valve, valve seat orifice is opened, thereby plays the autoregulation of air feed, has avoided the motionless and out of hand effect of stopcock rotation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the installation enlarged view of modulating valve among Fig. 1;
Fig. 4 is that the B of Fig. 3 is to view.
Embodiment
Among Fig. 1, one end of gas kitchen pipe joint 1 is screwed into the valve body 5 of outlet side band ring head, 4 of two valve seats have spherical valve body 3 in the inner chamber of valve body 5, valve rod 6 is installed in the sleeve on its top, the bottom of valve rod 6 is equipped with seal ring 10, and knob 7 usefulness screws 8 or pin are fixed on valve rod 6 tops, at the inner chamber of gas kitchen pipe joint 1, the setting sleeve 11 of opening subtend valve seat 4 is installed, and an end of setting sleeve 11 subtend gas kitchen pipe joints 1 inlet end has center hole; The modulating valve 2 that is installed in bar and spherical shell 20 compositions in the spherical shell 20 is slidably mounted in the setting sleeve 11, the shank of modulating valve 2 passes the center hole of setting sleeve 11, the top band one retaining platform 15 of handle, on the handle that keeps off 11 of platform 15 and setting sleeves, be with pressure spring 14 (referring to Fig. 3, Fig. 4), around the center hole of setting sleeve 11 gaily decorated basket shape or a plurality of uniform inlet hole 19 are arranged, inlet hole 19 continues up to the spherical shell portion of modulating valve 2 in free installment state.
Be the angle of swing of control handle 7, can open a fan-shaped restraining groove 17 (referring to Fig. 2) on the sleeve on valve body 5 tops, position limit pin 18 laterally penetrates in the valve rod 6 by restraining groove 17.
In combustion gas, have the impurity blocking pipe, can with back-up ring 13 filter screen 12 be pressed on the tube wall at the inlet end of gas kitchen pipe joint 1.
When preventing that gas valve from closing, modulating valve 2 is blocked the valve opening of ball valve 3, can establish a fore-set 16 at the spherical shell top of modulating valve 2, rotates spherical valve body 3 when closing gas valve, and its sphere opens breathing pipe the left end of modulating valve 2 tops to gas kitchen pipe joint 1; Open gas valve again, combustion gas can recover again to have ventilated.
