Abstract
The utility model relates to a valve plate mounting structure of blind plate valve. The problem that the current blind plate valve is sealed to effect is poor is mainly solved. The method is characterized in that: the bottom of the box body (1) is provided with a track (4), the lower end of the valve plate (2) is provided with a roller (6), and the roller (6) is positioned on the track (4); guide wheels (5) are arranged on two sides of the lower portion of the valve plate (2). The utility model discloses at valve bottom mounting rail, change the tradition and suspend the structure of valve plate in midair, the track passes through the gyro wheel and supports whole valve plate mechanism, can keep fine support intensity and plane degree for whole valve plate can even running at the switch in-process.
Description
Technical Field
The utility model relates to an industry special valve, concretely relates to valve plate mounting structure of blind plate valve.
Background
The blind plate valve is commonly used in the transmission pipelines of coal gas, natural gas, poisonous and harmful gas and inflammable chemical gas, and is mainly used for preventing leakage and absolutely cutting off during pipeline overhauling or maintenance. The blind plate valve is in an open state under a normal state, and only when parts are checked, maintained and replaced, the blind plate valve needs to be closed to ensure zero leakage of a pipeline. The existing blind plate valve comprises a box body, a valve plate, a middle valve body, a plate walking mechanism and an electric actuating mechanism, wherein the plate walking mechanism is installed above the box body, a rail is installed above the box body, and the valve plate is hung on the rail through rollers. The following technical defects exist when in use: 1. the mechanism is complicated, parts are heavy, a plate moving chain wheel is large, a large-diameter valve guide rail needs to bear the gravity of the whole valve plate mechanism and is easy to deform after being subjected to medium pressure, so that the coaxiality between the valve plate and the left valve body and between the valve plate and the middle valve body is poor when the valve plate is clamped, the sealing effect is poor, and gas such as coal gas and the like is seriously leaked. 2. The lower part of the valve plate mechanism is lack of support, the valve plate is easy to incline in the opening process, the valve plate is not stable in operation, and the sealing effect is affected by the abrasion of rubber on the sealing surface.
SUMMERY OF THE UTILITY MODEL
In order to solve the poor problem of current blind plate valve sealed effect, the utility model provides a valve plate mounting structure of blind plate valve, the valve plate mounting structure of this blind plate valve changes the tradition and suspends the structure of valve plate in midair bottom the valve at valve mounting rail, and the track passes through the gyro wheel and supports whole valve plate mechanism, can keep fine support intensity and plane degree for whole valve plate can even running at the switch in-process.
The technical scheme of the utility model is that: a valve plate mounting structure of a blind plate valve comprises a box body, a valve plate and a plate walking mechanism, wherein the plate walking mechanism is mounted above the box body, a track is mounted at the bottom of the box body, and a roller is mounted at the lower end of the valve plate and is positioned on the track; guide wheels are arranged on two sides of the lower portion of the valve plate.
The plate moving mechanism comprises a chain, and the upper part of the valve plate is connected to the chain.
The utility model discloses following beneficial effect has: due to the adoption of the technical scheme, the track is arranged at the bottom of the valve, the traditional structure for suspending the valve plate is changed, the track supports the whole valve plate mechanism through the rollers, and the good support strength and flatness can be kept, so that the whole valve plate can run stably in the opening and closing process.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of a prior art structure.
In the figure, 1-a box body, 2-a valve plate, 3-a plate moving mechanism, 4-a track, 5-a guide wheel and 6-a roller.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-2, the valve plate mounting structure of the blind plate valve comprises a box body 1, a valve plate 2 and a plate walking mechanism 3, wherein the plate walking mechanism 3 is mounted above the box body 1, a track 4 is mounted at the bottom of the box body 1, a roller 6 is mounted at the lower end of the valve plate 2, and the roller 6 is positioned on the track 4; guide wheels 5 are arranged on two sides of the lower portion of the valve plate 2. Due to the adoption of the technical scheme, the track 4 is arranged at the bottom of the valve, the traditional structure for suspending the valve plate is changed, the track 4 supports the whole valve plate mechanism through the roller 6, and the good support strength and flatness can be kept, so that the whole valve plate can run stably in the opening and closing process.
The plate moving mechanism 3 comprises a chain, and the upper part of the valve plate 2 is connected to the chain. The upper part of the valve plate 2 is limited by the chain, and the valve plate 2 can not incline to two sides. The chain plays the effect of transmission valve plate 2 on the one hand, and on the other hand also the upper portion of valve plate 2 plays limiting displacement.
The above embodiments should not be construed as limiting the present invention, and any of the various changes, modifications, substitutions and variations based on the spirit of the present invention should be considered within the scope of the present invention.
Claims (2)
