Abstract
The utility model relates to a coal gas isolating valve with a water seal system alarm function, which comprises a valve body composed of an upper valve body and a lower valve body, a screw rod which is arranged in the valve body, a wedge block which is arranged at the lower end of the screw rod, a valve plate which is positioned on the exterior of the wedge block, and a seal component which is installed on the valve plate, wherein the upper valve body is provided with a water injecting hole pipe, a water level display device and a gas exit hole, and the lower valve body is provided with an observation hole and a blow-off valve. The valve body is also provided with a water level alarm device. The utility model has the advantages that the water injection speed is high, the maintenance is convenient and users can know the water injection situation in the valve body. When the water level in the valve body gradually descends to a set position, the alarm device can send out alarm sound to remind workers to immediately add water to the valve body and the damage of the whole coal gas isolating valve is avoided.
Description
Technical field
The utility model belongs to valve, relates in particular to the shut off gas valve.
Background technique
The sealing of existing shut off gas valve is by a voussoir two valve plates to be strutted, and is pressed on the valve body sealing surface tightly.On the upper valve body of valve, be provided with water filling hole, this valve seal effect is better, and when valve open, the process valve plate that valve plate moves upward draws in to the centre, the valve plate seal ring does not contact fully with valve body sealing surface, has avoided the phase mutual friction between them, when injecting water behind the valve closing from water filling hole in valve cavity, avoided gas to shed, therefore this valve uses more safe and reliable.But what this valve valve plate upper sealing device adopted is a kind of rubber seal that installs thereon, very easily damage, inconvenience replacing again after the damage, when in valve pocket, not discharging smoothly because of intracavity gas during water filling behind the valve closing, therefore water filling is not smooth, this in addition valve also exists water injection rate to be difficult for checking, dirt deficiency such as easy to clean not in the valve body, the inventor is in the patent No. is 02214794.2 patent for this reason, it is better to disclose a kind of sealing effect, and Sealing is easily changed, and can improve waterflood injection rate in the valve body chamber, and water injection rate is easily checked, and can more conveniently observe situation and a kind of novel water seal shut off gas valve of removing dirt in the valve body in the valve pocket, no matter but water level is reduced to any degree to this valve, and it can not give the user with caution, and therefore this valve is fragile.
Summary of the invention
The purpose of this utility model is: provide a kind of easily water filling in the valve body chamber, and water injection rate checks easily, and can more conveniently observe situation in the valve pocket, when again can the water level in valve body being reduced to a certain position, can send the gas stop valve of warning function.
The present invention seeks to be achieved through the following technical solutions: this novel gas cut-off valve with seal water system warning performance, comprise the valve body formed by upper valve body and following valve body, be contained in the leading screw in the valve body, be contained in the voussoir of leading screw lower end and be positioned at the valve plate of voussoir outside and be contained in sealed member on the valve plate; Water injection hole pipe, level displaying device and exhaust port are arranged on upper valve body, on the following valve body peep hole and blowdown valve are housed, the water-level alarm device also is housed on the valve body.
The water-level alarm device is by the switch that links with lead, water level contact, relay, normally closed interlock, alarm, and normally open contact and tutorial light are formed, and the water level contact and the rolling off the production line of drawdown of warning device are touched.
Rolling off the production line of drawdown is arranged on down on the valve body.
The sealed member of adorning on the valve plate is a seal ring.
Described seal ring is that metallic material is made.
Described seal ring is that rubber material or plastics are made.
This shut off gas valve is behind valve closing, open water injection valve and carry out water filling, exhaust port on the valve body, waterflood injection rate has been improved, utilized the structure of valve seat in the sealed member, this has not only increased the sealing of valve body, and after damaging, it changes easily, this has brought very big convenience to maintenance, increased level displaying device on the upper valve body, on the following valve body peep hole is arranged, therefore make operator be convenient to understand the interior water filling situation of valve body and each element condition, be convenient to remove for dirt in the valve body; When water level in the valve body progressively dropped to a certain desired location, warning device will sound the alarm, and the staff will add entry immediately in valve body, guaranteed water seal, had also avoided the damage of whole gas stop valve.

The structural drawing that Fig. 1 cuts open for the utility model office of having;
Fig. 2 partly cuts open side view for Fig. 1's;
Fig. 3 is the electrical schematic diagram of seal water system warning device.
Embodiment
Embodiment: this novel gas cut-off valve with seal water system warning performance, be mainly used in gas pipe line, this valve adds water and forms water seal when valve plate decline and valve seal parts form sealing in valve pocket; This novel gas cut-off valve with seal water system warning performance, comprise upper valve body 1, the following valve body 4 that is assembled together by coupling and upper valve body 1, leading screw 8 is housed in valve body and is contained in the voussoir 9 of leading screw 8 lower ends and is positioned at the valve plate 10 of voussoir 9 outsides, sealed member 11 is housed on valve plate 10, sealing parts 11 can adopt seal ring, also can adopt known other Sealing, according to different media, sealed member 11 can select for use metallic material to make, and also can select for use rubber or plastic materials to make.Water injecting pipe 2 and exhaust port 7 are arranged on the upper valve body 1, water injection valve 2a is housed on water injecting pipe 2, for attractive in appearance, the present position just should be identical on upper valve body with water injecting pipe 2 for exhaust port 7, and should live apart in the both sides of valve body center line.For guaranteeing that more water injection rate is arranged, exhaust port 7 and water injecting pipe 2 all should be positioned at the shoulder of upper valve body 1 upper end.Valve 7a is housed on the exhaust port 7, and this valve 7a opens during water filling, so that run out of with the gas in the body cavity;
