Abstract

The utility model relates to a valve, in particular to a pipeline fluid switching valve. The pipeline fluid switching valve comprises a hollow valve element. A stopper is arranged in the valve element and divides an inner cavity of the valve element into a first cavity body and a second cavity body. A fluid outlet and a fluid inlet are formed in the outer wall of the valve element and communicated with the first valve body and the second valve body respectively. A sliding sleeve is connected to the valve element in a sleeved mode. The inner wall of the sliding sleeve is connected with the outer wall of the valve element through a first sealing ring, a second sealing ring and a third sealing ring, and the distance between the first sealing ring and the second sealing ring or the distance between the second sealing ring and the third sealing ring is larger than the distance between the fluid outlet and the fluid inlet. A first sliding sleeve stop piece and a second sliding sleeve stop piece are arranged at the two ends of the valve element respectively. The pipeline fluid switching valve can save space and is convenient to produce and operate.

Description

A kind of pipeline fluid switch valve

Technical field

The utility model relates to a kind of valve, relates to more specifically a kind of pipeline fluid switch valve.

Background technique

Although existing valve kind is a lot, for fluid valve, existing is all jug switch, has wasted space in the time opening or close, and installation and production have certain difficulty.

Summary of the invention

The utility model has designed a kind of valve, can ensure conserve space, produce and operate all fairly simple, the present invention has adopted following technological scheme: a kind of pipeline fluid switch valve, comprise hollow spool, in spool, be provided with the baffle element that valve core cavity is divided into the first cavity and the second cavity, on spool outer wall, be respectively equipped with the fluid output and the fluid input that communicate with the first cavity and the second cavity; Described valve core upper sleeve is connected to sliding sleeve, sliding sleeve inwall is connected with spool outer wall by the first seal ring, the second seal ring and the 3rd seal ring, and the interval of the interval of the first seal ring and the second seal ring or the second seal ring and the 3rd seal ring is greater than the spacing between fluid output and fluid input; The two ends of spool are respectively equipped with the first sliding sleeve block piece and the second sliding sleeve block piece.

Further, the first described sliding sleeve block piece is and the integrated assembly of spool.

Further, the second described sliding sleeve block piece is the nut matching with screw thread on spool.

Further, described seal ring is that quality of rubber materials is made.

In above-mentioned technological scheme, because seal ring itself has certain thickness, between sliding sleeve inwall and spool, there is so certain space, so just there is an intersegmental gap to be beneficial to flowing of fluid between seal ring and seal ring.

The beneficial effects of the utility model are: adopt the utility model, saved that existing switch is positioned at valve body outside and space has been saved in the space waste that causes, and produce and operation all very simple.

embodiment

Below in conjunction with accompanying drawing and the preferred specific embodiment of the present invention, the present invention is done to set forth further: the first embodiment, a kind of pipeline fluid switch valve, fluid in the drawings for from enter, from lower outflow, comprise hollow spool 1, in spool 1, be provided with the baffle element that spool 1 inner chamber is divided into the first cavity 12 and the second cavity 13, on spool 1 outer wall, be respectively equipped with the fluid output 32 and the fluid input 31 that communicate with the first cavity 12 and the second cavity 13; On described spool 1, be socketed with sliding sleeve 2, sliding sleeve 2 inwalls are connected with spool 1 outer wall by the first seal ring 21, the second seal ring 22 and the 3rd seal ring 23, and the interval of the first seal ring 21 and the second seal ring 22 is greater than the spacing between fluid output 32 and fluid input 31; The two ends of spool 1 are respectively equipped with the first sliding sleeve block piece 16 and the second sliding sleeve block piece 17, wherein, the first sliding sleeve block piece 16 is and the integrated assembly of spool 1, the nut of the second sliding sleeve block piece 17 for matching with screw thread on spool 1, and seal ring is that quality of rubber materials is made.

The second embodiment, be with first embodiment's difference, the interval of the second seal ring 22 and the 3rd seal ring 23 is greater than the spacing between fluid output 32 and fluid input 31, fluid flows into from below, flow out from top, principle is the same with the first embodiment, is just fluid output and fluid input exchange.

Above embodiment is only part preferred embodiment, and any principle is identical with the utility model, is all that the utility model is available, and the embodiment who enumerates is only explanation essence of the present utility model, can not become constraint example of the present utility model.
