The reversing valve is widely applied to petroleum and chemical production and is most commonly used in a synthetic ammonia gas making system. In addition, the reversing valve can also be made into a valve clack type structure, is mostly used in occasions with small flow, and when the reversing valve works, the hand wheel is rotated, and the flow direction of fluid is controlled through the change of the valve core.
Most of manual reversing valves in the prior art are of an integrated structure, so that the manual reversing valves are inconvenient to disassemble and relevant maintenance such as cleaning of the manual reversing valves is realized.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a manual reversing valve has solved the most formula structures as an organic whole of current manual reversing valve, and the not convenient to detach is to its inside problem of relevant maintenance such as clearing up.
The technical scheme is as follows: the utility model relates to a manual reversing valve, include the main part and install at its outside action bars, the main part is including closely laminating each other and through bolt fixed connection's first valve body and second valve body, the inside of second valve body is equipped with mobile cavity, one side of second valve body be equipped with mobile cavity communicating manhole and first discharge hole, the second valve body be equipped with mobile cavity communicating second discharge hole with one side that the action bars is relative, the action bars is close to one side of second valve body and installs the actuating lever that stretches into to mobile cavity, the actuating lever is located mobile cavity's one end fixed mounting has the case that the mobile cavity of control opened and shut.
Furthermore, a sealing rubber ring is arranged between the second valve body and the first valve body.
Furthermore, the four corners of the top end face of the second valve body are provided with positioning screw holes, the four corners of the first valve body are provided with mounting holes penetrating through the first valve body, and the positions of the mounting holes correspond to the positions of the positioning screw holes.
Further, a bolt is installed in the installation hole along the vertical direction and is in threaded connection with the positioning screw hole.
Further, the inlet hole and the first discharge hole are arranged in parallel, and the inlet hole is arranged perpendicular to the flow chamber.
Further, the flow chamber, the inlet orifice, the first outlet orifice and the second outlet orifice all have the same inner diameter.
Has the advantages that: the utility model discloses a dismantle the bolt in the mounting hole, can make first valve body and the separation of second valve body to be convenient for clear up flowing the cavity inside, make the maintenance of manual switching-over valve more convenient.

FIG. 2 is a schematic structural view of a first valve body;
fig. 3 is a schematic structural view of the second valve body.
Detailed Description
The invention will be further described with reference to the following figures and examples:
as shown in fig. 1 to 3, the present invention relates to a manual directional control valve, which comprises a main body 1 and an operating rod 2 installed outside the main body, wherein the operating rod 2 is installed on the main body 1 in the same way as the rod body of a directional control valve with the model number of 34SM-L10H-W, the main body 1 comprises a first valve body 11 and a second valve body 12 which are tightly attached to each other and fixedly connected by bolts, a sealing rubber ring 3 is arranged between the second valve body 12 and the first valve body 11, and the sealing rubber ring 3 increases the sealing performance of the manual directional control valve;
a flow chamber 4 is arranged in the second valve body 12, an inlet hole 5 and a first discharge hole 6 communicated with the flow chamber 4 are arranged on one side of the second valve body 12, the inlet hole 5 and the first discharge hole 6 are arranged in parallel, the inlet hole 5 is arranged perpendicular to the flow chamber 4, a second discharge hole 7 communicated with the flow chamber 4 is arranged on one side of the second valve body 12 opposite to the operating rod 2, the inner diameters of the flow chamber 4, the inlet hole 5, the first discharge hole 6 and the second discharge hole 7 are the same, a driving rod 8 extending into the flow chamber 4 is arranged on one side of the operating rod 2 close to the second valve body 12, and a valve core 9 for controlling the opening and closing of the flow chamber 4 is fixedly arranged at one end of the driving rod 8 positioned in the flow chamber 4;
four corners of the top end surface of the second valve body 12 are provided with positioning screw holes 121, four corners of the first valve body 11 are provided with mounting holes 111 penetrating through the first valve body 11, and the positions of the mounting holes 111 correspond to the positions of the positioning screw holes 121; a bolt 112 is arranged in the mounting hole 111 along the vertical direction, and the bolt 112 is in threaded connection with the positioning screw hole 121; the first valve body 11 and the second valve body 12 can be separated by detaching the bolt 112 in the mounting hole 111, so that the inside of the flow chamber 4 can be cleaned conveniently, and the maintenance of the manual reversing valve is more convenient.
The working principle is as follows: when in use, hydraulic oil enters from the inlet hole 5, and a person operates the operating rod 2 to control the driving rod 8 to move, so that the valve core 9 moves to a proper position in the flow chamber 4, and the hydraulic oil is determined to be discharged from the first discharge hole 6 or discharged from the second discharge hole 7; if operations such as cleaning the inside of the flow chamber 4 or maintenance of the valve element 9 are required, the four sets of bolts 112 are removed to separate the first valve element 11 from the second valve element 12, and then the maintenance can be performed easily.
