Abstract
The utility model discloses a multistage sealing valve seat of a flat brake valve, which comprises a valve body, a valve plate, a valve rod, a valve cover, a lengthening section assembly and a power-driven execution structure. The valve plate is arranged in a valve body, the power-driven execution structure is connected with the valve plate in transmission mode through the lengthening section assembly and the valve rod, the valve seat is arranged on the combining portion of the valve body and the valve plate, a hard sealing ring is arranged on the inner side of the valve seat, and a sealing ring is arranged on the outer side of the hard sealing ring. A soft sealing ring is added on the valve seat based on the existing hard sealing ring, so that the sealing effect of the valve plate is improved. The soft sealing ring in the multistage sealing valve seat adopts an O-shaped sealing ring, the effect of zero leakage is achieved, the soft sealing ring is matched with the hard sealing ring on the valve seat, and the effect of multistage is achieved due to the combination of the soft sealing ring and the hard sealing ring. Therefore, the inner structure of the valve body has better sealing effects, and leakage of media in the valve body can be prevented.
Description
Technical field
The utility model relates to a kind of plate valve, relates in particular to the multi-stage sealed valve seat on a kind of plate valve.
Background technique
Plate valve is applicable to transfer line such as rock gas, oil, chemical industry, environmental protection, urban duct, burning line, on blowdown system and the vapour storage device, as opening and closing device.Band pod apertures Single disc formula plate valve is applicable to the long-distance transport pipes of natural gas extraction and purification.
The flow resistance of plate valve is less, and its flow resistance is similar with short flow resistance by all means.The plate valve of band pod apertures is installed on the pipeline and also can directly carries out pigging with wiper.Because flashboard is on two valve seat surfaces, to slide, so the plate valve fluid power is applicable to that the sealing surface of medium, the plate valve of band suspended particulate is actually automatic location.But be sealed with certain slit between the valve seat of existing plate valve and the valve plate, be easy to generate leakage.
The model utility content
The purpose of the utility model is to solve the problems of the prior art, a kind of good airproof performance is provided, can makes medium reach the plate valve of zero leakage.
The technological scheme of the utility model is: the multi-stage sealed valve seat of a kind of plate valve; Comprise valve body, valve plate, valve rod, valve gap, extension assembly and electronic execution architecture; Said valve plate is arranged in the said valve body, and electronic execution architecture is in transmission connection through said extension assembly, valve rod and said valve plate, is provided with valve seat in the connecting part of said valve body and valve plate; The inboard of said valve seat is provided with the gravity die seal ring, in said gravity die seal ring arranged outside seal ring is arranged.
Said seal ring is soft RunddichtringO.
Said soft RunddichtringO is the O RunddichtringO.
Said O RunddichtringO is fixedly installed on the valve seat outside through compact heap, and said compact heap is through being bolted on the valve body.
Valve seat in the utility model adds soft RunddichtringO on the basis of original gravity die seal ring, increased the sealing effect of valve plate; Soft RunddichtringO adopts the O RunddichtringO in the utility model; Reach the effect of zero leakage, cooperated original two O RunddichtringOs on the valve seat, realized multi-stage sealed effect; Make the valve inner structure have better sealing effect, prevented the leakage of medium in the valve body.
Description of drawings
Fig. 1 is the utility model construction of parallel gate valve schematic representation;
Fig. 2 is the valve seat enlarged view among Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1: as to be a kind of plate valve; Comprise valve body 14, valve plate 13, valve rod 12, valve gap 11, extension assembly 10 and electronic execution architecture 9, closed fixed between valve body 14 and the valve gap 11, said valve plate 13 is arranged in the said valve body 14; Valve plate 13 is under the drive of valve rod 12; Control action has been played in circulation to valve body 14 interior medias, can realize the effect that the interior media accent flows through valve plate 13, such as the adjusting to media such as oil or rock gases.
Electronic execution architecture 9 is in transmission connection with said valve plate 13 through said extension assembly 10, valve rod 12; When electronic execution architecture 9 is rotated; Extension assembly 10 can move under the power of electronic execution architecture 9, thereby drives the rotation of valve rod 12 and valve plate 13.
As shown in Figure 2: the connecting part at said valve body 14 and valve plate 13 is provided with valve seat 8, is provided with gravity die seal ring 3 in the inboard of said valve seat 8, on valve seat 8, also is provided with spring 6; Spring 6 is arranged in the hole that valve seat 8 one sides offer; Bottom and valve body 14 connecting parts at valve seat 8 are provided with two O RunddichtringOs 4,5, in the arranged outside of said gravity die seal ring 3 soft RunddichtringO 2 are arranged; For the O RunddichtringO has best sealing effect, can reach the effect of zero leakage in the present embodiment.Said soft RunddichtringO 2 is fixedly installed on the inboard of valve seat 8 through pressure strip 1, and said pressure strip is through being bolted on the valve seat 8, has prevented in valve plate 13 motions generation with the phenomenon of soft RunddichtringO 2 extruding landings.
Being merely the utility model preferred embodiment in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
