Abstract
The utility model discloses a novel elastic seal gas gate valve capable of being connected with a PE pipe. The novel elastic seal gas gate valve comprises a valve body, a cone square head, a gate plate and a valve rod. The lower end of the cone square head is connected with the upper end of the valve rod. The lower end of the valve rod is connected with the upper end of the gate plate. The valve body comprises a round pipe and a calabash-shaped cavity connected with the middle of the round pipe. The interior of the round pipe is smooth. The cavity comprises an upper flange and a lower flange. The lower portion of the cone square head is provided with a back seal compressing ring and a back seal rubber ring. The lower portion of the cone square head and the cavity are sealed through the back seal compressing ring and the back seal rubber ring. Tooth-shaped grooves are formed inside the two ends of the round pipe. Pressing sleeves are arranged outside the two ends of the round pipe. The novel elastic seal gas gate valve capable of being directly connected with the PE pipe is designed according to the characteristic of an urban gas pipe network, no dirt is accumulated, maintenance is not required, and the emission function is achieved.
Description
Technical field
The utility model relates to a kind of Gas-combustion valve, relates in particular to a kind ofly can manage the elastic packing novel gas gate valve being connected with PE.
Background technique
Gas-combustion valve the planning of city gas pipeline with build in extensively use, traditional Gas-combustion valve has comprised buried plate valve and the large class of Wedge gate valve two, buried plate valve, by unsteady valve seat and parallel type flashboard, under elastomer pretightening force and pressure medium effect, is realized sealing; Wedge gate valve rotates by screw thread valve rod, drives flashboard lifting, realizes sealing by the wedging of flashboard and valve seat.Above-mentioned two kinds of Gas-combustion valves exist following shortcoming:
(1) plate valve soft and hard seal and the equal more complicated of floating valve seat structure;
(2) design of bottom groove, easily causes dirt to stockpile;
(3) friction of metal to metal easily causes scratch, and the easy corrosion of metal, causes poorly sealed;
(4) general equal can not directly connection with PE polyethylene gas pipe.
