Problems solved by technology

[0003] Since throttle valves are generally used in hydraulic systems, hollow hinge bolts are often required to connect hydraulic parts and pipelines in hydraulic systems. Throttle valve, both the throttle valve and the hinged bolt are separated, they need to be installed and positioned separately during installation and use, the process is relatively troublesome, and the failure rate is also high at this time, which is not conducive to maintenance and brings inconvenience to use

Abstract

The invention discloses a throttling valve comprising a valve body (1), a valve core (2) and a regulating rod (3), wherein the valve core (2) is arranged in the valve body (1), the external diameter of the head part at the upper end of the valve body (1) is larger than that of the part below the head part, the part below the head part of the valve body (1) is provided with an external thread, thevalve wall below the head part of the valve body is provided with a plurality of horizontal channels (4), the valve body (1) is in a vertically through mode, the regulating rod is partially arranged in the valve body (1) from top to bottom and supports against one end of the valve core (2), the other end of the valve core (2) is connected with one end of a spring I (5), and the other end of the spring I (5) is fixed at an opening at the lower end of the valve body. By adopting the invention, the traditional function of the throttling valve can be realized, and the outer shape of the valve body is equivalent to that of a hinged screw so as to ensure the connecting function for a hydraulic part and a pipeline. Therefore, the invention integrates the hinged screw and the throttling valve.

Description

technical field [0001] The invention relates to the field of valves, in particular to a throttle valve. Background technique [0002] A throttle valve is a valve that controls fluid flow by changing the throttle area or throttle length. The throttle valve in the prior art generally includes a valve body, a valve core and an adjusting rod. The valve body is provided with a liquid inlet and a For the liquid outlet, the valve core is arranged in the valve body, and the adjusting rod is used to adjust the position of the valve core in the valve body, thereby adjusting the liquid flow in the valve body. [0003] Since the throttle valve is generally used in the hydraulic system, and the hydraulic parts in the hydraulic system and the pipeline often need hollow hinge bolts to connect, when the throttle valve needs to be used, it is necessary to install a throttle on the pipeline The throttling valve, i.e. the throttling valve and the hinged bolt are separated, and need to be inst...
