Abstract
The utility model discloses a socket-type flexible-seat gate valve which comprises a valve body. A sealing valve deck is connected with the valve body; a center shaft passes through the valve deck and is sealed with the valve deck; the lower part of the center shaft is connected with an elastic flashboard; a seal groove is formed on an inner pipe wall of a medium inlet section and/or a medium outlet section of a valve body flow passage; and a pipeline sealing element is arranged in the seal groove. The socket-type flexible-seat gate valve adopts the pipeline sealing element positioned in the inner pipe wall of the medium inlet section and/or the medium outlet section of the valve body flow passage. A tube can be directly inserted into the medium inlet section and/or the medium outlet section of the valve body flow passage, thereby being convenient to install rapidly; and the selection range of the tube can be wider at the same time. A rubber seal is arranged at a socket interface of the socket-type gate valve, a pipeline can deflect a certain angle, and the stress generated by external loads in the pipeline can be reduced.
Description
Technical field
The utility model belongs to gate valve, is specifically related to a kind of elastic seat sealed gate valve.
Background technique
Valve on the present water supply network is embedded in underground, and it is to adopt flange to be connected with bolt that present most of valves are connected with pipeline, and such is rigidly connected, and the weakness that can not reduce stress is arranged.For example: because the stress that road load or severe cold cause causes underground type fire hydrant or valve to break.In addition, because of valve connect need be on pipeline welded flange, so the corrosion-inhibiting coating of pipeline is destroyed, the etching problem that flange connects is a well-known difficult problem.The flange elastic sluice valve with wedge-shaped sealing face need be at the pipeline welding flange, and the easy destroyed generation of pipeline coatings is leaked during welding; The gate valve of flange connection needs bolt to connect in addition, uses bolt to be corroded for a long time, thereby causes flange to connect blow-by.
Summary of the invention
The purpose of this utility model is to provide the spigot and socket type elastic sluice valve with wedge-shaped sealing face of a kind of valve and the pipeline quick connection that non-flange is connected, to address the above problem.
The technical solution of the utility model is: the spigot and socket type elastic sluice valve with wedge-shaped sealing face, it comprises valve body, connect sealed valve cap on the valve body, central shaft passes valve gap and sealing with it, central shaft connects Flexible disc down, the medium inducer of valve flowing channel and/or the inner tubal wall of media outlet section are offered seal groove, are provided with conduit seals in the seal groove.
The conduit seals of the medium inducer of the utility model employing valve flowing channel and/or the inner tubal wall of media outlet section.Can directly pipe fitting be inserted in the medium inducer and/or media outlet section of valve flowing channel, be convenient to install fast, simultaneously more extensive for the range of choice of pipe fitting.The spigot and socket type gate valve is provided with rubber seal at the bell and spigot joint place, and pipeline can have certain angle excursion, can reduce the stress that external load produces in pipeline.
Description of drawings
Fig. 1 spigot and socket type elastic sluice valve with wedge-shaped sealing face structural representation.
Embodiment
As shown in Figure 1, valve body 1 is connected by bolt with valve gap 2 and seals by valve bonnet seal part 8.Central shaft 4 passes valve gap 2 by sealing between gland 3, Sealing 9 and split bearing and the valve gap 2.Central shaft 4 connects Flexible disc 5.
The medium inducer 11 of valve flowing channel and the inner tubal wall of media outlet section 12 are offered seal groove 13, are provided with conduit seals 6 in the seal groove 13.Be provided with limited step 14 in the medium inducer 11 of valve flowing channel and/or the media outlet section 12.Display medium outlet section 12 internal structure among the present embodiment figure.Conduit seals 9 is an elastomer seal; Elastomer seal is a rubber seal.When this valve is connected with pipeline, can directly pipeline 7 be inserted the medium inducer 11 and the media outlet section 12 of valve flowing channel, seal by conduit seals 6 between pipeline 7 and valve body 1 wall, and spacing by limited step 14.
