Abstract
A stop valve, specifically provide a set of stop valves for hydraulic system, it has adopted a brand-new cylindrical flat valve core, locate in the middle of the valve block vertically, the flat part couples to inlet, oil outlet, both ends are cylindrical and couples to valve block. When the square head handle rotates 90 degrees, the flat part in the middle of the valve core is communicated with the oil passages on two sides of the valve body, pressure oil passes through the flat part, and the oil passages are closed when the flat part rotates 90 degrees reversely. It is easy to manufacture and maintain, and has improved service life and reliability.
Description
Technical Field
The utility model relates to a stop valve specifically is to provide one set of stop valve for hydraulic system, and it has adopted the flat case of a brand-new cylinder type, and the passageway of advancing, going out pressure oil can be set for wantonly.
Background
The existing stop valves are divided into ball valves, cylindrical valves and conical valves according to the types of valve cores, and the ball valves, the cylindrical valves and the conical valves have the defects of complex processing manufacturability, difficult manufacturing, difficult maintenance, frequent oil leakage, short service life and uneconomical performance and become the bottleneck in the development of hydraulic systems.
Disclosure of Invention
The utility model discloses a hydraulic system provides a processing technology nature is simple, overall dimension is little, the application is nimble, long service life, the stop valve that the reliability is high, and it has adopted the flat case of cylinder type, and when the flat part in the middle of the 90 case of rotating square head handle and the oil duct intercommunication on valve body both sides, pressure oil passes through, and 90 oil circuits of reversal are closed.
The stop valve is connected by valve body, case, retaining ring, sealing washer in proper order, and the case is arranged in the valve body perpendicularly, and middle flat part links to each other with valve body business turn over pressure oilhole, and both ends are cylindrical and link to each other with the valve body, and when rotatory 90 pressure oil passes through, the reversal then closes. The valve core extends to a square head handle at one end of the outer side of the valve body and is controlled to rotate 90 degrees when working. And the upper part and the lower part of the valve core are respectively provided with a sealing ring connected with the valve body. The channels for the inlet and outlet of the pressure oil can be set arbitrarily. Both ends of the valve core are provided with check rings for fixation.
By adopting the scheme, the efficiency, the function and the reliability are improved, the structure is simple, the processing and the maintenance are easy, the parts which are easy to damage are easy to replace, the service life is prolonged, and the adopted components are all common components, so that the realization is easy, and the economic benefit is obvious.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention
FIG. 2 is a cross-sectional view taken along line B-B of FIG. 1
FIG. 3A-A section view of FIG. 1
In the figure, the valve comprises a valve core 1, a valve body 2, valve bodies 3 and 6, an oil inlet, an oil outlet 4, a sealing ring 5 and a retainer ring.
Detailed Description
The valve core 1 is vertically arranged in the valve body 2, the middle of the valve core 1 is flat and is communicated with the pressure oil inlet and outlet holes 3 and 6, the upper part of the valve core is a square-head handle, the upper end and the lower end of the valve core are both provided with check rings 5 for fixation, the inner end of the valve core is provided with a leakage-proof sealing ring 4, when the valve core rotates 90 degrees in work, pressure oil passes through the valve core, and when the valve core rotates.
Claims (5)
