Abstract
A manual stop valve is a set of stop valves provided for a hydraulic system, and adopts a brand new cylindrical valve core. When the handle rotates 90 degrees, the through hole in the middle of the valve core is communicated with the oil ducts on two sides of the valve body, pressure oil passes through the through hole, the valve core hole rotates 90 degrees in a reverse mode, the through hole is disconnected with the valve body hole, and the oil duct is closed. It is easy to manufacture and maintain, and has improved service life and reliability.
Description
Technical Field
The utility model relates to a manual stop valve specifically is for hydraulic system provides one set of stop valve, and it has adopted a brand-new cylindrical valve core, and the passageway of advancing, going out pressure oil can be set for wantonly.
Background
The existing manual stop valves are ball valves, are complex in processing manufacturability, difficult to manufacture, prone to oil leakage, inconvenient to install and maintain, short in service life and uneconomical, and become bottlenecks 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 manual stop valve that the reliability is high, and it has adopted the cylinder type case, when turning handle 90, the through-hole in the middle of the case and the oil duct on valve body both sides intercommunication, pressure oil pass through, and reversal 90, case hole and valve body hole disconnection, the oil circuit is closed.
The manual stop valve is connected in proper order by valve body, handle, case, locating pin, stifled, sealing washer, and in the case perpendicular to valve body, upper portion communicated with handle, well through-hole and valve body pressure oilhole intercommunication that advances, pressure oil passes through, and is closed if not. The positioning pin on the handle is inserted into the arc-shaped groove of the valve body, and the control handle rotates 90 degrees when working. And sealing rings connected with the valve body are arranged above and below the valve core. The channels for the inlet and outlet of the pressure oil can be set arbitrarily.
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 original devices are all common original devices, so the method is easy to realize and has obvious economic benefit.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention
FIG. 2 top view of FIG. 1
FIG. 3A-A plan view of FIG. 1
In the figure, the valve comprises a valve body 1, a valve core 2, a valve core 3, a handle 4, a positioning pin 5, a plug 6, an oil inlet and an oil outlet 7, a seal ring 8 and a seal ring.
Detailed Description
The valve core 2 is vertically arranged in the valve body 1, the upper part of the valve core 2 is connected with the handle 3, a through hole in the valve core 2 is communicated with the oil inlet and outlet holes 6 and 7 when pressure oil is introduced, the pressure oil is closed when the pressure oil is not introduced, the positioning pin 4 on the handle 3 is inserted into the arc-shaped groove control handle 3 of the valve body 1 and rotates 90 degrees when the valve core is in operation, the right side of the valve body 1 is provided with a plug 5 for processing a process hole of an oil path channel, and the upper part and the lower part of the valve core 2 are provided with oil leakage-proof sealing.
