Description
Technical field
The present invention relates to valve field, is a kind of throttle valve specifically.
Background technique
Throttle valve is by changing orifice size or the chock length valve with the control fluid flow, the throttle valve of prior art generally comprises valve body, spool and adjustable lever, described valve body is provided with liquid entering hole and liquid outlet, described spool is arranged in the valve body, described adjustable lever is in order to the position of regulating spool in valve body, thus the fluid flow in the regulation valve body.
Because throttle valve generally is used in the hydraulic system, and often need hollow hinge bolt to connect between hydraulic part in the hydraulic system and the pipeline, when needs use throttle valve, need throttle valve is installed on pipeline separately, both throttle valve separated with hinge bolt, need distinguish installing and locating when installing and use, operation bothers relatively, this moment, rate of fault was also higher, was unfavorable for maintenance, had brought inconvenience to use.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of throttle valve that can play interconnect function to the hydraulic part and the pipeline of hydraulic system is provided, and promptly collecting hinge bolt and throttle valve is one.
Technical solution of the present invention is, a kind of throttle valve of following structure is provided, and comprises valve body, spool and adjustable lever, and described spool is arranged in the valve body; The external diameter of described valve body upper end head is greater than the external diameter of head with the bottom, described valve head is provided with outside thread with the bottom, the head of valve body is provided with some crosspassages with the valve wall of bottom, described valve body up/down perforation, adjustable lever partly places in the valve body from top to bottom and withstands an end of spool, the other end of described spool is connected with the end of spring I, and the other end of spring I is fixed on the valve body lower end opening.
Adopt above structure, the present invention compared with prior art has the following advantages: adopt structure of the present invention, can the valve body lower end opening be liquid entering hole both, with the crosspassage is liquid outlet, can crosspassage be liquid entering hole also simultaneously, the valve body lower end opening be a liquid outlet, comes the position of regulating spool in valve body by adjustable lever, thereby the circulation area between regulation valve body lower ending opening and the crosspassage, the purpose of realization throttling; The external shape of valve body is equivalent to a hinge bolt, can play interconnect function to hydraulic part and pipeline, makes the present invention collect hinge bolt and throttle valve is an one.
As improvement, be provided with valve core channel in the described spool, be provided with one-way valve in the described valve core channel, also be provided with the some return flow lines that communicate with valve core channel on the described valve body, described return flow line is positioned at the top of crosspassage, like this, in the time of feed liquor, one-way valve does not circulate, during backflow, the liquid of locating of liquid outlet can be pushed one-way valve open, liquid return has been accelerated the speed that refluxes to the liquid entering hole place, thereby has made things convenient for the backflow of liquid, be particularly useful for the fast hydraulic system of needs backflow, increased the function of throttle valve.
As improvement, described valve body lower end opening is a liquid entering hole, crosspassage is a liquid outlet, described one-way valve comprises back-up ring, spring II and nonreturn valve core, described back-up ring is installed in the lower end of valve core channel, and described spring II one end is fixed on the back-up ring, and the other end is fixed on the nonreturn valve core, described valve core channel is set to shoulder hole near the place, return flow line, and described nonreturn valve core withstands shoulder hole.This structure is to be liquid entering hole with the valve body lower end opening, and crosspassage is a liquid outlet, and when liquid entered, because one-way valve does not circulate, liquid can only flow out from crosspassage, regulates the discharge value of liquid entering hole and liquid outlet by the position of regulating spool; When liquid return, liquid enters the valve core channel in the spool from the return flow line, and pushes nonreturn valve core open, thereby makes liquid be back to the liquid entering hole place fast, has strengthened the controllability of throttle valve.
As improvement, described valve body lower end opening is a liquid outlet, crosspassage is a liquid entering hole, described one-way valve comprises back-up ring, spring II and nonreturn valve core, described back-up ring is installed in the upper end of valve core channel, and described spring II one end is fixed on the back-up ring, and the other end is fixed on the nonreturn valve core, described valve core channel is set to shoulder hole near the valve body lower end opening, and described nonreturn valve core withstands shoulder hole.This structure is to be liquid outlet with the valve body lower end opening, crosspassage is a liquid entering hole, when liquid when crosspassage enters, because one-way valve does not circulate, liquid flows out from the valve body lower end opening, the discharge value of regulating liquid entering hole and liquid outlet by the position of regulating spool; When liquid return, liquid enters valve core channel in the spool from the valve body lower end opening, and pushes nonreturn valve core open, thereby makes liquid be back to the liquid entering hole place fast, has strengthened the controllability of throttle valve.
As improvement, described adjustable lever is an adjusting screw rod, described adjusting screw rod screws from top to bottom in valve body and withstands spool, like this, by the handwheel on the manual rotation adjusting screw rod, make adjusting screw rod precession or back-out, thereby can control the position with regulating spool better, made things convenient for the adjusting of flow.
As improvement, described adjustable lever is a depression bar, be provided with the depression bar cover between described depression bar and the valve body, like this, by depression bar is exerted pressure, just can promote depression bar and move downward, thereby regulate fluid flow, promptly the stroke by the control depression bar comes the controlling liquid flow, makes the present invention become stroke throttle valve
As improvement, described depression bar puts and is provided with the depression bar limit structure, the effect of depression bar limit structure is to prevent that the elastic force of spring I from promoting spool and depression bar moves upward, make the complete and crosspassage disengaging of spool, thereby lose the effect of regulating flow, the depression bar limit structure moves upward spool and depression bar and is controlled in certain scope, has prevented above-mentioned phenomenon effectively.
As improvement, described depression bar limit structure comprises spring III and gland, and described gland is arranged between depression bar cover and the depression bar, described depression bar is provided with step, described spring III one end withstands step, and the other end withstands gland, thereby has realized spacing to spool and depression bar.
As improvement, the top of described depression bar is provided with roller, and like this, when depression bar was exerted pressure, the friction between object and the depression bar was rolling friction, thereby had reduced the loss of depression bar, had prolonged the working life of depression bar.
