Description

A kind of Double-clack cast steel stop valve

Technical field

This utility model belongs to valve field, particularly relates to a kind of Double-clack cast steel stop valve.

Background technology

Valve is the control parts in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief. The opening and closing element of stop valve is the flap of stopper, and sealing is plane or the sea conical surface above, can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium. Due to the valve rod of such valve, to be turned on and off stroke relatively short, and has cutting function very reliably. Therefore, the stop valve valve that dams is highly suitable as cut-out and throttling is used. Existing stop valve is two-way valve, valve is only provided with a fluid inlet channel, a fluid outlet channels, it is impossible to realize the connection of three pipelines.

The technical scheme that this utility model adopts is:

A kind of Double-clack cast steel stop valve, it is characterized in that: include valve body, first flap, second flap, connecting rod, valve rod, turn axis fixing plate, limiting plate, check plate, rotating shaft, drainage screen, described valve body offers fluid inlet channel, first fluid exit passageway, second fluid exit passageway, described fluid inlet channel, the first port it is provided with between first fluid exit passageway, described fluid inlet channel, the second port it is provided with between second fluid exit passageway, described first port, second port is oppositely arranged in parallel, described first port is fixed with the first sealing ring, described second port is fixed with the second sealing ring, described first flap is positioned at the inside of described first fluid exit passageway and it is inserted in described first sealing ring, described second flap is positioned at the inside of described second fluid exit passageway and it is positioned at the side of described second port, one end of described connecting rod is connected with the first flap and its other end and the second flap are connected, described valve rod is installed in described valve body, described valve rod be electric expansion bar and its be connected with described first flap, the described axis fixing plate that turns is fixed on the side of described fluid inlet channel, described rotating shaft turns on axis fixing plate described in being fixed on, described limiting plate is fixed on the opposite side of described fluid inlet channel, one end of described check plate is fixed in described rotating shaft and fits and be arranged at the side of described limiting plate in its lower end, described filter network card is located at the end of described fluid inlet channel.

Described check plate is fixed with cushion towards the side of described limiting plate.

Described valve body is cast steel valve body.

The beneficial effects of the utility model are:

1, this utility model is provided with a fluid inlet channel, two fluid outlet channels, forms the version of threeway, it is achieved that by three pipeline connections, expand range of application;

2, in use, one flap is plugged in a passage port, another flap is positioned at the side of another port, after driven the first flap, the second flap to move by valve rod simultaneously, and conversion flap, port closure relation, realizing the switching of fluid outlet channels, conversion is convenient;

3, the setting of two sealing rings, good sealing effect;

4, valve rod is electric expansion bar, and automaticity is high, and manipulation is convenient;

5, the setting of check plate, effectively prevents fluid from driving in the wrong direction;

6, drainage screen is used for filtering dirt, it is prevented that valve internal blocks;

7, check plate is fixed with cushion towards the side of limiting plate, it is prevented that limiting plate damages, long service life.
