Abstract
The invention provides an energy-saving and safe gas valve capable of automatically opening and closing. A valve body (1) is linked with a motor (10). The gas valve is characterized in that a screw rod (7) is matched on an output gear (9) on a motor retarding mechanism; a screw barrel (18) is matched on the screw rod; the front end of the screw barrel is connected with a spring seat (3); the spring seat is provided with a spring (2) and a support (5) integrally formed by a sleeve part and a baffle part; the sleeve part of the support can be radially sleeved outside the spring seat and the spring in a movable manner; the inner end of the spring pushes against the retaining wall with caliber extending inwards in the sleeve part of the support; a valve seal (6) used for sealing the valve seat at the exit of the valve body leans against the front of the baffle part of the support; and the valve seal is sleeved in the sleeve part of the support. The gas valve is suitable for gas systems.
Description
Technical field
The present invention relates to gas valve, particularly a kind of gas valve with automatic on-off function.
Background technique
The development and utilization of fuel gas source not only brings great convenience to people's lives, has created advantage also for the development of all conglomeraties comprise industry, service trade, utilize fuel gas generation for civilian use and industrial be an example.When a large amount of development and utilizations of fuel gas source offer convenience to the mankind, also at a large amount of consumption of natural resource, and produce inevitably pollution.The enforcement of the exploitation in the western gas field of China and transfering natural gas from the west to the east one lineman's journey, two wires engineering is improved for the national economic development and people's living standard and has produced very large effect.But the same with other energy, always there is contradiction in the supply of fuel gas source with consumption, and the situation that supply falls short of demand is long-term existence always.On the other hand, because combustion gas is flammable explosive gas, if improper use or because a variety of causes causes leakage all major accident may occur.
Just there are many potential safety hazards with regard to Domestic cylinder liquid gas and pipeline gas.Bottled gas has generally just been installed a reduction valve and has then directly been connect gas cooking range at present, if kitchen range or adapter are because of quality or a large amount of leakages of personal factor appearance, and reduction valve does not possess automatic closing function, just causes the combustion gas waste and very likely produces security incident.The Household pipe gas user side has also just been installed gas meter and common valve, causes waste and produces security incident because can not automatically cutting off source of the gas in case occur to leak also.
On combustion gas is used, economizing on gas and the safe gas of using in a word, is two large important topics all the time.
A kind of valve is installed in the gas pipeline system, except opening and closing by normal mode, valve energy autoshutdown or unlatching when the inlet/outlet directional pressure changes, this valve has very big meaning for economizing on gas and safe usefulness gas.But yet there are no simple in structure in the prior art and gas valve that have the automatic on-off function also has no relevant report.
Summary of the invention
The present invention will solve the gas valve of the energy automatic on-off of installing and using on the present shortage gas supply pipeline, thereby may cause the problem of combustion gas waste and generation security incident, the gas valve of a kind of energy automatic on-off of the present invention is provided for this reason, this gas valve is energy autoshutdown or unlatching when the inlet, outlet directional pressure changes, thereby reaches the purpose of economizing on gas and safe usefulness gas.
For addressing the above problem, the technical solution used in the present invention is to be associated with motor at valve body, its special way is to be combined with screw mandrel on the output gear of motor decelerating mechanism, be combined with swivel nut on the screw mandrel, the swivel nut front end is connected with spring seat, be provided with spring on the spring seat, be provided with the support that is consisted of by sleeve part and baffle part one, the sleeve part of this support can be placed on described spring seat and spring outside with moving radially, described spring the inner relies on the footpath of bracket sleeve tube part internal orifice and inwardly prolongs retaining wall, and support baffle part front is by being provided with the jam pot cover for closed valve outlet valve seat.
Described jam pot cover can be placed on the sleeve part of support.
Described valve rear end should be associated with front shroud and the back shroud of axial space, the reducing gear of described motor is comprised of motor gear, the described output gear that is engaged in a gear of motor gear and is engaged in a gear, and gear and output gear are between described front shroud and back shroud.
Be combined with on the described output gear screw mandrel refer to screw mandrel through the coaxial corotation of key be coupled to output gear, screw mandrel is arranged with screw rodb base outward, this screw rodb base is fixed in described front shroud.
Be provided with out vent plug in the described bracket sleeve tube part front end, be provided with sealing gasket in the annular groove of back-end support.
The present invention can be installed on the pipe-line system use to be placed in gas pipeline in the valve body.
The present invention is owing to be combined with swivel nut on the motor-driven screw mandrel, be associated with spring seat on the swivel nut, spring seat is provided with spring, be provided with support, the sleeve part of support can be placed in spring seat and spring outside with moving radially, support baffle plate front is provided with the jam pot cover of closing valve seat, described spring the inner relies on the back-end support retaining wall, so motor driving screw mandrel band movable snail sleeve, when spring seat and spring move radially and move to valve opening position, spring can drive support and jam pot cover moves to valve opening position, Open valve, at this moment, support is to drive by mobile spring together with the opening movement of jam pot cover; When support and jam pot cover are opened under the valve seat state, airintake direction pressure is greater than the outgassing direction certain value, when acting on airintake direction pressure on support and the jam pot cover and being enough to overcome spring pressure, support together with jam pot cover from trend valve seat direction motion throttle down; And when inlet, outlet directional pressure relative equilibrium, the two pressure difference is during less than spring pressure, and valve will be opened (it is prerequisite that swivel nut, spring seat are in out the valve state) automatically.So the present invention is when swivel nut and spring seat are in out the valve state, along with the inlet, outlet directional pressure changes, valve can autoshutdown or is automatically opened.As, this valve is under the normal opening state, when valve body outgassing direction system gas leakage build-up of pressure drops to certain value, and valve meeting autoshutdown, thus guaranteeing safety, Accident prevention occurs.
