Abstract
The utility model discloses a hand-operated direction valve which comprises a valve body, a valve rod, a spring, a driving lever, a manual wheel, a hand wheel sleeve and a pin shaft. The valve body is a main body of the direction valve, the valve rod is a valve rod assembly in the valve body, the spring is arranged at the top end of the valve rod, the spring guarantees that the valve rod can move back and forth while the valve rod is driven, the driving lever is sleeved in the hand wheel sleeve, one end of the driving lever is contacted with the head of the valve rod, the hand wheel sleeve is sleeved in an end port of the valve body to do axial sliding rather than vertical sliding, a hand wheel is arranged at the bottom end of the valve body to drive the hand wheel sleeve to rotate, the pin shaft is arranged at the position of the end port of the valve body, and the pin shaft drives the valve rod to advance or draw back to drive the valve rod to move to achieve oil-way connection, oil-way disconnection or switch of the direction valve through the hand wheel sleeve and the driving lever. The hand-operated direction valve is simple in structure, novel in conception, flexible in reversing, compact in structure and strong in generality, saves cost during production, saves space during installation and is convenient to operate.
Description
Technical field
The utility model belongs to the manufacturing of a kind of valve class, and what relate generally to is a kind of hand-operated direction valve.
Background technique
Selector valve is the position control valve with two or more liquid forms and two above hydraulic fluid ports, communication, cut-out and the commutation that realizes hydraulic oil stream, and the valve of discharge degree and sequentially-operating control, this transfer valve has a wide range of applications in oil, Chemical Manufacture, and is the most commonly used in the ammonia system.In addition, selector valve also can make the structure of clack type, and is multiplex in the occasion than small flow.Only need rotate handwheel comes the conversion working fluid by flap the flow direction during work.Hand-operated direction valve of the prior art is to rely on the active force actuate valve stem of hand lever to move to realize the position control valve that switches, the resistance of the manually operated valve manual reverse of direction of this structure is very large, when being pressed increase, it is large that the resistance of seal ring also becomes thereupon, hand-operated direction valve for spring reset, the phenomenon that sometimes can reset and block, and seal ring can wear and tear, and affects the working life of valve.Installation dimension is made troubles with using owing to the restriction of handle height increases in addition.
The model utility content
The purpose of this utility model namely produces thus, proposes a kind of commutation flexible, a kind of hand-operated direction valve of compact structure.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of hand-operated direction valve, comprise valve body, valve rod, spring, driving lever, manual pulley, handwheel sleeve and bearing pin, described valve body is the main body of selector valve, described valve rod is the valve rod assembly at valve inner, described spring is in valve stem tip, when spring had guaranteed actuate valve stem, valve rod can move back and forth, and described driving lever is set in the handwheel sleeve, one end of driving lever contacts with the valve rod head, described handwheel sleeve is enclosed within the port of valve body, does endwisely slipping, and does not do radially sliding, described handwheel is in the valve body bottom, effect is can drive handwheel sleeve to rotate, and described bearing pin is in the port of valve body, through handwheel sleeve and driving lever, by with the propelling of ovable valve stem or retreat, reach the position control valve that actuate valve stem moves to realize oil circuit break-make or switching.
The utility model design is unique, and simple in structure, highly versatile has been saved cost during production, saved space and easy-to-operat during installation.
Description of drawings
Fig. 1 is a kind of sectional drawing of hand-operated direction valve.
Wherein: the 1-valve body, the 2-valve rod, the 3-spring, the 4-driving lever, the 5-handwheel sleeve, 6-is opinion manually, the 7-bearing pin.
Embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1: a kind of hand-operated direction valve, comprise valve body, valve rod, spring, driving lever, manual pulley, handwheel sleeve and bearing pin, described valve body is the main body of selector valve, described valve rod is the valve rod assembly at valve inner, described spring is in valve stem tip, when spring has guaranteed actuate valve stem, valve rod can move back and forth, described driving lever is set in the handwheel sleeve, and an end of driving lever contacts with the valve rod head, and described handwheel sleeve is enclosed within the port of valve body, do and endwisely slip, do not do radially sliding, described handwheel is in the valve body bottom, and effect is can drive handwheel sleeve to rotate, described bearing pin is in the port of valve body, through handwheel sleeve and driving lever, by with the propelling of ovable valve stem or retreat, reach the position control valve that actuate valve stem moves to realize oil circuit break-make or switching.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technological scheme of unrestricted the utility model; Therefore, although the utility model book has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technological scheme and the improvement thereof of the spirit and scope of model utility, and it all should be encompassed in the middle of the claim scope of the present utility model.
