The utility model comprises a valve body, a valve rod and a check valve, one side of the valve body is provided with a water inlet channel, and the other side of the valve body is provided with a water outlet channel, a partition baffle is arranged between the water inlet channel and the water outlet channel, and the water inlet channel and the water outlet channel are connected by an ach-shaped pipe at the lower part of the valve body, a check valve block is arranged at the connection position of the ach-shaped pipe and the water outlet channel, one end of the valve block is mounted on the spindle of a valve block fixing seat, the valve block fixing seat is fixed on the water outlet channel side valve body, the water outlet channel side valve body is also provided with a valve rod mounting channel which is vertical and aligned with the check valve block, the valve rod is mounted on the valve rod seat at the upper part of the valve rod mounting channel, and the lower end of the valve rod is aligned with the check valve block. The utility model is mainly applied to the switch for controlling fluid.
Description
Technical field:
The utility model relates to a kind of against current valve, is specifically related to a kind of against current valve with switch gear.
Background technique:
Against current valve is a kind of and allows medium to flow to a direction, and stops the valve that flows in the other direction.This valve is under the fluid pressure action that a direction flows, and flap is opened; When fluid flows, act on valve seat in the other direction, flow, prevent the valve that flows backwards thereby cut off by the flap of coincidence certainly of hydrodynamic pressure and/or flap.Against current valve can divide according to its structure: one, rise-fall type against current valve: the against current valve that flap slides along the valve body vertical center line.Two, rotary-open type against current valve: flap is around the against current valve of the outer bearing pin rotation of valve seat.Three, dish formula against current valve: the against current valve that flap rotates around the bearing pin in the valve seat.Four, pipe type against current valve: the valve that flap slides along the valve body center line.But shortcomings such as inconvenience are used in the restriction that the position that these against current valves are installed has, and complex structure.
Summary of the invention:
The purpose of this utility model has provided a kind of simple in structure, easy to use, the against current valve of belt switch.
The utility model is achieved by the following technical programs:
The against current valve of belt switch of the present utility model comprises valve body, valve rod and non-return valve block, one side of valve body is an intake tunnel, opposite side is an exhalant canal, between described intake tunnel and exhalant canal, be provided with one and separate plate washer, described intake tunnel and exhalant canal are connected by the arc pipe of being located at valve body lower portion, connection mouth place at described arc pipe and exhalant canal is provided with the non-return valve block, one end of this valve block is installed in the rotating shaft of valve block fixed base, described valve block fixed base is fixed on the valve body of exhalant canal one side, also have the valve rod that vertically faces the non-return valve block in exhalant canal one side passage is installed, valve rod is installed in valve rod and installs on the valve rod base on passage top, and the lower end of valve rod faces the non-return valve block.
Described non-return valve block is corresponding with the arc pipe opening, the airtight arc pipe of energy, and this valve block is that fulcrum rotates up and down with the rotating shaft of valve block fixed base, thereby makes arc pipe airtight or open-minded.
Also be provided with stop nut on the described valve rod, this stop nut effect is, when valve rod rises to maximum position, be that stop nut is when blocking valve interior wall, valve block still can be blocked in the lower end of this valve rod, valve block can only be rotated, in certain zone when valve rod descends, valve block can be pushed back airtight arc pipe.Can certainly be provided with banking stop on fixed base, this banking stop only allows valve block to rotate in certain zone, when valve rod descends, valve block can be pushed back airtight arc pipe.
Described valve rod and valve rod are installed between the passage and are fixedlyed connected by screw thread, also can be equipped with handle on described valve rod, with actuate valve stem rotation and lifting easily.
The utility model is such use: current flow into from intake tunnel, the arc pipe of flowing through again, and when valve rod did not compress the non-return valve block, current were washed the non-return valve block open and are flowed out from exhalant canal.When adverse current took place, current flowed into from exhalant canal, the non-return valve block under the pressure of current, the airtight arc pipe of living, thus the blocking-up current prevent adverse current.When valve rod descends, press down the non-return valve block, make the airtight firmly arc pipe of valve block, close this against current valve.
The utility model had both had the effect of against current valve, can prevent the current adverse current, had the effect of switch again, made things convenient for cut-off valve, and simple in structure, easy to manufacture, easy to use.
Description of drawings:
Fig. 1 is that the utility model switch is in the structural representation when opening;
Fig. 2 is that the utility model switch is in the structural representation when cutting out;
Fig. 3 is that the utility model switch is in when opening, the structural representation during the current adverse current;
Embodiment:
As Fig. 1, shown in 2 and 3, the utility model comprises the valve body 1 of a tubulose, the cavity that has in the valve body 1, one side of valve body is an intake tunnel 12, an other side is an exhalant canal 11, between described intake tunnel 12 and exhalant canal 11, be provided with a separation baffles 7, described intake tunnel 12 and exhalant canal 11 are connected by the arc pipe 3 of being located at valve body lower portion, connection mouth place at described arc pipe 3 and exhalant canal 11 is provided with non-return valve block 5, on the valve body of exhalant canal one side, be equipped with valve block fixed base 8, one end of non-return valve block is installed in the rotating shaft of valve block fixed base 8, valve block is that fulcrum rotates up and down with the rotating shaft of valve block fixed base, thereby it is airtight or open arc pipe, also have the valve rod that vertically faces non-return valve block 5 in exhalant canal 11 1 sides path 10 is installed, valve rod 2 is installed in valve rod and installs on the valve rod base 9 on passage top, valve rod 2 is fixedlyed connected by screw thread with valve rod installation path 10, the lower end of valve rod 2 faces non-return valve block 5, also be provided with stop nut 6 on valve rod, the upper end of valve rod is equipped with handle 4.
The utility model is such use: current flow into from intake tunnel, the arc pipe of flowing through again, and when valve rod did not compress the non-return valve block, current were washed the non-return valve block open and are flowed out (as shown in Figure 1) from exhalant canal.When adverse current took place, current flowed into from exhalant canal, and the non-return valve block seals up arc pipe under the pressure of current, thereby the blocking-up current prevent adverse current (as shown in Figure 3).Work as rotating handles, valve rod is descended, press down the non-return valve block, make valve block seal up arc pipe, just closed this against current valve (as shown in Figure 2).
