Description
Technical field
This utility model belongs to valve field, is specifically related to a kind of stop valve.
Background technology
Stop valve, is also pipe valve, due in its opening and closing process between sealing surface frictional force little, relatively durable, Lift is little, easy to manufacture, easy to maintenance, is applicable not only to mesolow, and is applicable to high pressure, is use one of relatively broad valve. The Guan Bi principle of stop valve is, relies on valve thick stick pressure, makes valve clack sealing surface and sealing surface of seat fit tightly, and stops medium circulation.
The opening and closing element of stop valve is the flap of stopper, and in use, the sealing property between flap and valve seat reduces the flap of stop valve, it is easy to the situations such as leakage occur, the service life of product is affected. Based on this, this utility model provides a kind of stop valve, can improve the sealing property between flap and valve.
Summary of the invention
For the problem of sealing between flap and the valve seat of the stop valve mentioned in solution background technology, this utility model provides a kind of stop valve.
This utility model solves the technical problem that and is achieved through the following technical solutions:
A kind of stop valve, including: valve body 1, fluid intake 2, flap 3, valve rod 4, handle 5, Pressure gauge 6, valve gap 7, sealing ring 8, fluid issuing 9 and connector 10. Described valve body 1 top and valve gap 7 weld; It is internal that described valve rod 4 stretches into valve body 1 through valve gap 7, and described valve rod 4 top is connected to Pressure gauge 6, and described valve rod 4 top is connected to handle 5; The design of described valve rod 4 lower end has flap 3; Described flap 3 is vertical profile cross section is two cylindrical structures up and down of " T-shaped ", and on described flap 3, below column structure, edge is provided with sealing ring 8, and 3 times column structures of described flap insert connector 10 and close contact when Guan Bi; Described valve body 1 left end is fluid intake 2, and described valve body 1 right-hand member is fluid issuing 9.
Beneficial effect
The beneficial effects of the utility model are:
This utility model provides a kind of stop valve, easy to manufacture, easy to maintenance, and range of application is relatively wide, can improve the sealing property between flap and valve, avoids the generation of the situations such as leakage preferably, improves the service life of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-valve body, 2-fluid intake, 3-flap, 4-valve rod, 5-handle, 6-Pressure gauge, 7-valve gap, 8-sealing ring, 9-fluid issuing, 10-connector.
Specific embodiments
Below in conjunction with accompanying drawing, this utility model is described further:
A kind of stop valve, including: valve body 1, fluid intake 2, flap 3, valve rod 4, handle 5, Pressure gauge 6, valve gap 7, sealing ring 8, fluid issuing 9 and connector 10. Described valve body 1 top and valve gap 7 carry out sealing welding, and it is internal that described valve rod 4 stretches into valve body 1 through valve gap 7, and described valve rod 4 top is connected to Pressure gauge 6, and described Pressure gauge can show the fluid pressure within valve body 1.
Described valve rod 4 top is connected to handle 5, and turning handle 5 can band ovable valve stem 4 so that it is rotate downward or upward, thus controlling Guan Bi and the unlatching of this stop valve. To have flap 3, described flap 3 be vertical profile cross section to the design of described valve rod 4 lower end is two cylindrical structures up and down of " T-shaped ", and on described flap 3, below column structure, edge is provided with sealing ring 8, effectively prevents the leakage of fluid; 3 times column structures of described flap insert connector 10 and close contact when Guan Bi, and convection cell is stopped. Described valve body 1 left end is fluid intake 2, and described valve body 1 right-hand member is fluid issuing 9.
