Abstract
The utility model relates to the technical field of hydraulic valves, in particular to a three-position four-way manual valve used on a manual hydraulic pump. The three-position four-way manual valve comprises a valve body, a handle, an oil inlet, an oil outlet, an oil flow hole and an oil return hole, wherein the oil inlet, the oil outlet, the oil flow hole and the oil return hole are arranged on the valve body. A rotating shaft connected with the handle is arranged in the valve body. The lower end of the rotating shaft in the valve body is connected with a pin shaft. A composite sealing ring is arranged between the pin shaft and the valve body. A gasket and a sealing ring are arranged between the rotating shaft and the valve body. The handle is connected with the rotating shaft through a spring pin. The utility model has the advantages that the application scope is wide, the three-position four-way manual valve can be widely used in heavy machinery industries such as shipbuilding industry, petrochemical industry, power industry, metallurgy industry, bridge industry, railway industry and the like, the sealing performance of the entire structure is good, the allowable pressure rating is high, and the service life is long.
Description
Technical field
The utility model relates to the hydrovalve technical field, especially a kind of 3-position 4-way manually operated valve that is applied on the hydraulic hand-pump.
Background technique
At present, mostly the 3-position 4-way valve arrangement of widespread is that handle drives the guiding valve operation in the valve body on the market, be that a cartridge type slide-valve piece is installed in three-position four-way valve, the move left and right according to pulling of handle, thereby finishing commutation, is that the motion seal ring seals, and its sealability is not very high, the effect of bearing pressure is also not so good, and the life-span of use is shorter.
The model utility content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of 3-position 4-way manually operated valve is provided, and be widely used in having double-acting Hydraulic power tools.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of 3-position 4-way manually operated valve, have valve body, handle, be opened in oil inlet hole and oil outlet and oil flow hole and spill port on the valve body, be provided with the rotating shaft that links to each other with handle in the valve body, rotating shaft lower end in the valve body is connected with bearing pin, by pulling handle, realize commutation.
Further, in order to make the sealing effect of bearing pin reach best, be provided with composite sealing ring between bearing pin and valve body.
In order to improve the sealability of rotating shaft, be provided with packing ring and seal ring between rotating shaft and valve body.
For convenience handle drives the motion of rotating shaft, is connected by resilient key between handle and rotating shaft.
The beneficial effects of the utility model are 3-position 4-way manually operated valve of the present utility model, applied range, relate generally to heavy machinery industries such as shipbuilding, petrochemical industry, electric power, metallurgy, bridge, railway, integrally-built sealability is better, and the pressure rating of bearing is higher, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the overall structure plan view of Fig. 1.
Among the figure 1, valve body, 2, handle, 3, oil inlet hole, 4, oil outlet, 5, oil flow hole, 6, spill port, 7, rotating shaft, 8, bearing pin, 9, composite sealing ring, 10, packing ring, 11, seal ring, 12, resilient key.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The 3-position 4-way manually operated valve of preferred forms as shown in Figure 1, have valve body 1, handle 2, be opened in oil inlet hole 3 and oil outlet 4 and oil flow hole 5 and spill port 6 on the valve body 1, be provided with the rotating shaft 7 that links to each other with handle 2 in the valve body 1, rotating shaft 7 lower ends in the valve body 1 are connected with bearing pin 8,1 of bearing pin 8 and valve body are provided with composite sealing ring 9,1 of rotating shaft 7 and valve body are provided with packing ring 10 and seal ring 11, and 7 of handle 2 and rotating shafts are connected by resilient key 12.
When the utility model is implemented, driving rotating shaft 7 with handle 2 rotates, according to different positions and bearing pin 8 butt joints, diverse location that rotating shaft 7 is rotated and 8 butt joints of different bearing pins, finish commutation, oil flow hole 5 when handle 2 is up pulled and down pulled with handle 2 is put upside down mutually with spill port 6, and promptly the oil flow hole 5 of handle 2 upwards the time be the spill port 6 of handle 2 downwards the time, and the spill port 6 of handle 2 upwards the time is handle 2 oil flow hole 5 when downward.Sealing is that the plane by rotating shaft 7 and bearing pin 8 seals firmly, can be more perfect than product hermeticity in the past, the pressure rating of bearing is higher, simultaneously, selecting for use of material, critical piece of the present utility model, as rotating shaft 7 and bearing pin 8 all is to support with High Alloy Steel, through hot quenching and grinding, prolonged working life, on valve body 1, made valve body 1 parts such as grade with the fine aluminum alloy, improved in the past the shortcoming in the coarse and quality sheet of the bend pipe of making of foundry goods, further perfect the utility model.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
