Abstract
The utility model discloses a low-cost hand-operated reversing valve which comprises a front cover, a valve, a push rod, a rotary sleeve and a rotary knob. The front cover and the valve are connected with each other and form a shaft hole, the shaft hole is perforated through the front cover, both the push rod and the rotary sleeve are axially fittingly mounted in the shaft hole, the push rod can axially move, the rotary sleeve can axially rotate, a lug is arranged on the push rod, a rotary groove is formed in the rotary sleeve, and the plug is arranged on the rotary groove, so that the rotary sleeve can be rotationally matched with the push rod, and the rotary knob is arranged on the outer side of the valve and is fixedly connected with the rotary sleeve. The low-cost hand-operated reversing valve has the advantages of extremely simple structure and low cost.
Description
Technical field
The utility model belongs to a kind of valve body field, is specifically related to the hand-operated direction valve that a kind of cost is low.
Background technique
Traditional hand-operated direction valve includes handle, end cap, push rod, hinge axis and pin; One end of described pin is plugged on push rod, and the other end is fixedly connected with hinge axis, and described hinge axis is connected with handle, and when operation, described handle drives the pin on hinge axis to rotate take hinge axis as axle center, thereby promotes push rod to realize operation.But this structure is very complicated.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to make the structure of hand-operated direction valve simpler.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the hand-operated direction valve that a kind of cost is low, comprises protecgulum, valve body, push rod, rotation set and turn-knob; Described protecgulum is connected with valve body and forms an axis hole, described axis hole runs through protecgulum, described push rod and rotation set all axially coordinate and are arranged in axis hole, wherein push rod can move axially, rotation set can axial-rotation, and described push rod and rotation set are respectively arranged with projection and swivelling chute, and described projection is arranged on swivelling chute rotation set is coordinated with push rod rotation, described turn-knob arranges the outside of valve body, and is fixedly connected with rotation set.
Described axis hole have include at least one take axis hole as shaft axis the uniform draw-in groove of annular; Described push rod also includes at least one fixture block coordinating with draw-in groove, and described fixture block is arranged in draw-in groove also removable.
Described fixture block and draw-in groove all have 2.
Described rotation set includes a hole of not running through, and described swivelling chute is arranged on the side in hole, and described push rod is plugged in hole.
The material of described turn-knob is plastics.
(3) beneficial effect
The hand-operated direction valve that cost of the present utility model is low, by the tooth bar clamping of ratchet and push rod of hinge axis is set, moves thereby start push rod, without the pin that transmission is set, thereby makes the overall structure of hand-operated direction valve simpler, has reduced again cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hand-operated direction valve that cost of the present utility model is low;
Fig. 2 is the sectional view of A-A in Fig. 1;
Fig. 3 be in Fig. 1 B to view;
In figure, 1 is that protecgulum, 2 is that valve body, 3 is that push rod, 4 is that rotation set, 5 is that turn-knob, 6 is that projection, 7 is that swivelling chute, 8 is that axis hole, 9 is that draw-in groove, 10 is that fixture block, 11 is hole.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The low hand-operated direction valve of a kind of cost as shown in Figure 1-Figure 3, comprises protecgulum 1, valve body 2, push rod 3, rotation set 4 and turn-knob 5; Described protecgulum 1 is connected with valve body 2 and forms an axis hole 8, described axis hole 8 runs through protecgulum 1, described push rod 3 and rotation set 4 all axially coordinate and are arranged in axis hole 8, wherein push rod 3 can move axially, rotation set 4 can axial-rotation, and described push rod 3 is respectively arranged with projection 6 and swivelling chute 7 with rotation set 4, and described projection 6 is arranged on swivelling chute 7 and makes rotation set 4 rotate and coordinate with push rod 3, described turn-knob 5 arranges the outside of valve body 2, and is fixedly connected with rotation set 4.Drive the swivelling chute 7 of rotation set 4 to rotate by turn-knob 5, described swivelling chute 7 drives projection 6 to control push rod 3 transverse shiftings, thus realize hand-operated direction valve structure and operation simpler, cost is lower.
Described axis hole 8 have include 2 take axis hole 8 as shaft axis the uniform draw-in groove 9 of annular; Described push rod 3 also includes 2 fixture blocks 10 that coordinate with draw-in groove 9, and described fixture block 10 is arranged in draw-in groove 9 also removable.
Described rotation set 4 includes a hole of not running through 11, and described swivelling chute 7 is arranged on the side in hole 11, and described push rod 3 is plugged in hole 11.
The material of described turn-knob 5 is plastics.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
