Abstract
The invention provides an exhaust device for gas meter valves, which can prevent pressure in a cavity of a gas meter valve from increasing and guarantee the long-term normal work of the valve. A sealing cover with a through hole is arranged on a valve body cavity; an exhaust plug (4) is inlaid in the through hole of the sealing cover; the exhaust plug is provided with a blind hole (41) which has the inner end opened and is communicated with the valve body cavity (1); the upper part of the exhaust plug is provided with an exhaust gap (42); the inner mouth of the exhaust gap (42) is communicated with the blind hole of the exhaust plug; and the outer mouth of the exhaust gap (42) is communicated with the external environment of the cavity (1). The exhaust device is suitable to be arranged onthe gas meter valve so as to ensure that the valve can normally work for a long time.
Description
Technical field
The present invention relates to the assembly with degassing function of gas meter electric valve assembly, particularly gas meter electric valve.
Background technique
The electronic opening/shutting valve of gas meter in the prior art is a device of sealing relatively.Under normal circumstances this valve is positive confinement, and the combustion gas of valve cavity outside can't enter the valve inside cavity in gas meter, and this moment, the valve internal pressure balance can realize normal keying.But when valve is in when leaking operating mode slowly, it was worked in gas meter after a period of time, because valve inside cavity and outside exist certain pressure poor, the combustion gas meeting is diffused into the valve inside cavity gradually, enter the combustion gas meeting of valve inside cavity and the parts of valve internal, particularly parts such as plastics, rubber generation chemical reaction and produce gas increases valve internal pressure gradually, and internal gas can not in time be discharged again.When pressure that valve internal pressure can bear greater than valve, valve just loses the keying function, can't open.
Summary of the invention
The present invention will solve the electronic opening/shutting valve of gas meter and cause that because of leaking slowly the increase of valve internal pressure causes the problem that can't open, a kind of exhaust for gas meter valve of the present invention is provided for this reason, this device is arranged at gas meter valve, it can in time get rid of the gas that the valve internal pressure increases part, even leaking slowly, valve can not cause valve not open yet, make valve reliable, long service life.
For addressing the above problem, its special way of the technical solution used in the present invention is the capping that is provided with the tool through hole in valve chamber, the described through hole of capping is embedded with the exhaust plug, blind hole and valve chamber that the exhaust plug has interior end opening connect, exhaust plug top is provided with the slit of giving vent to anger, the blind hole of slit internal orifice and described exhaust plug of giving vent to anger connects slit collar extension and the chamber external environmemt perforation of giving vent to anger.
The capping of described tool through hole is meant this capping: this capping has shroud, and the shroud lower ending opening runs through chamber, and shroud top has the air outlet, and described through hole is meant that shroud lower ending opening, top have the inner chamber of air outlet.
Described exhaust plug is a particularly rubber material system exhaust plug of plastic material.
Chamber external environmemt of the present invention typically refers to gas meter inner chamber environment, and the gas meter inner chamber has combustion gas, and valve is arranged at the gas meter inner chamber.
The present invention is owing to establish through hole in the capping of valve chamber, the through hole is embedded with the exhaust plug, and exhaust plug top is provided with the slit of giving vent to anger, and the blind hole in give vent to anger slit internal orifice and the exhaust plug connects, and give vent to anger slit collar extension and valve cavity outdoor environment connect; When valve cavity pressure increased, opened in the slit of giving vent to anger on the exhaust plug, discharges gas; And during valve extraneous gas extruding exhaust plug, the slit of giving vent to anger on the exhaust plug is closed tightly, extraneous gas can not enter in the valve, so the present invention can in time get rid of the gas that the valve air pressure inside increases part, make the valve pressure that always is in the normal state, pressing in avoiding occurring increases the situation that causes valve not open, and guarantees that valve can long-term proper functioning.

Embodiment
Exhaust for gas meter valve, be in valve chamber, to establish capping 2, this capping has shroud 21, the shroud lower ending opening runs through chamber 1, shroud top has air outlet 211, be embedded with rubber material system exhaust plug 4 in the shroud, exhaust plug outer wall has the two-stage step that radially shrinks successively from bottom to top, exhaust plug lower edge retaining is buckled in shroud lower ending opening portion, has gap 3 between external wall of upper portion that exhaust plug radial dimension is relatively little and the shroud inwall, the blind hole 41 that the exhaust plug has interior end opening connects with valve chamber 1, exhaust plug upper portion side wall is provided with two slits 42 of giving vent to anger of radial symmetric, and exhaust plug end face is provided with the slit 43 of giving vent to anger, and the blind hole 41 with give vent to anger slit internal orifice and exhaust plug end face sidewall connects, described give vent to anger slit collar extension and the perforation of chamber 1 external environmemt, this external environmemt is a gas meter inner chamber environment.
When valve chamber 1 internal air pressure increases, as when the slow leakage situation of valve occurring can, the blind hole 41 that this moment, chamber 1 interior gas entered exhaust plug 4, the slit 42,43 of exhaust plug is opened, form as Fig. 4, shown in Figure 6 opening and stitch 421,431,, discharge by the air outlet hole on the shroud 211 again just gas is discharged from opening seam 421,431, make valve internal keep the normal pressure state, guarantee that valve normally moves.
Claims (3)
1. exhaust for gas meter valve, it is characterized in that valve chamber is provided with capping (2), this capping has shroud (21), the shroud lower ending opening runs through chamber (1), shroud top has air outlet (211), be embedded with exhaust plug (4) in the shroud, the blind hole (41) that the exhaust plug has interior end opening connects with valve chamber (1), exhaust plug top is provided with the slit of giving vent to anger (42), the blind hole of slit (42) internal orifice and described exhaust plug of giving vent to anger connects the slit of giving vent to anger (42) collar extension and the perforation of chamber (1) external environmemt.
