Technological scheme: for solving the problems of the technologies described above, a kind of hand expansion valve of the present utility model, comprise valve body, be positioned at the valve seat of valve body, be positioned at the valve gap above valve body, the first valve plate and the second valve plate that cooperatively interact is provided with in valve seat, first valve plate upper end is provided with tapped hole, the side of upper end is provided with the first sphenoid surface, lower end is provided with and obtuse-angulate second sphenoid surface of the first sphenoid surface angle, second valve plate upper end is provided with the 3rd sphenoid surface coordinated with the first sphenoid surface, the lower end of the second valve plate is provided with the 4th sphenoid surface coordinated with the second sphenoid surface, valve body, first valve plate and the second valve plate are provided with drain hole, in tapped hole, valve rod is installed, seal arrangement is provided with between valve rod and valve gap, the top of valve rod is provided with handwheel.
As preferably, below described valve seat, be provided with guide plate.
As preferably, described seal arrangement comprises stem packing, Gland, plane thrust ball bearing, separation sleeve, gland nut and locking nut, and stem packing, Gland, plane thrust ball bearing, separation sleeve, gland nut and locking nut are enclosed within valve rod successively.
As preferably, the upper end of described valve body is provided with step trough, and valve gap lower end is cone table shape, is provided with valve bonnet seal circle in step trough, and the cone table shape lower end of valve gap is pressed on valve bonnet seal circle.
Beneficial effect: hand expansion valve of the present utility model, adjusts the position of the first valve plate and the second valve plate by valve rod, adjust the position of drain hole in the first valve plate and the second valve plate, the size of flow in control valve body, and adjustment is simple, good sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of hand expansion valve of the present utility model, comprise valve body 1, be positioned at the valve seat 3 of valve body 1, be positioned at the valve gap 7 above valve body 1, the first valve plate 14 and the second valve plate 4 cooperatively interacted is provided with in valve seat 3, first valve plate 14 upper end is provided with tapped hole, the side of upper end is provided with the first sphenoid surface, lower end is provided with and obtuse-angulate second sphenoid surface of the first sphenoid surface angle, second valve plate 4 upper end is provided with the 3rd sphenoid surface coordinated with the first sphenoid surface, the lower end of the second valve plate 4 is provided with the 4th sphenoid surface coordinated with the second sphenoid surface, valve body 1, first valve plate 14 and the second valve plate 4 are provided with drain hole, valve rod 5 is installed in tapped hole, seal arrangement is provided with between valve rod 5 and valve gap 7, the top of valve rod 5 is provided with handwheel 16.
In the utility model, be provided with guide plate 2 below valve seat 3, the top of guide plate 2 is conical, and valve seat 3 lower end is positioned on conical top; Seal arrangement comprises stem packing 8, Gland 9, plane thrust ball bearing 10, separation sleeve 11, gland nut 12 and locking nut 13, stem packing 8, Gland 9, plane thrust ball bearing 10, separation sleeve 11, gland nut 12 and locking nut 13 are enclosed within valve rod 5 successively, by gland nut 12 and locking nut 13, can better seal; The upper end of valve body 1 is provided with step trough, and valve gap 7 lower end is cone table shape, is provided with valve bonnet seal circle 6 in step trough, the cone table shape lower end of valve gap 7 is pressed on valve bonnet seal circle 6, valve gap 7 is bolted on valve body 1, due to valve bonnet seal circle 6, makes valve body 1 can be good at sealing.
The utility model in use, rotated by handwheel 16, band ovable valve stem 5 rotates, thus drives the moving up and down, when the first valve plate 14 moves down of the first valve plate 14, due to the effect of the first sphenoid surface, second valve plate 4 is moved down, the drain hole on the drain hole on valve body 1 and the first valve plate 14 is staggered, the flow of adjustment valve body 1 fluid, simultaneously due to the effect of the second sphenoid surface and the 4th sphenoid surface, make valve seat 3 tightly be adjacent to valve body 1; When the first valve plate 14 moves up, the second valve plate 4 moves up simultaneously, the drain hole on adjustment valve body 1 and the drain hole relative position on the first valve plate 14, the flow of adjustment valve body 1 fluid.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
