Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides an embodiment: go up valve body (14) and lower valve body (1) coaxial orientation, disk seat (3) are located lower valve body (1) inner peripheral surface, and valve rod (2) are located disk seat (3) pole hole inner peripheral surface, and lower valve body (1) export flange becomes 45 with valve rod (2), and valve rod (2) overcoat has valve disc (5), holding down plate (7), and valve disc (5) cooperation portion has the annular groove, and embedded dress sealing washer (8).
The valve rod (2) is located on the inner peripheral surface of the guide rod (17), the guide rod (17) and the upper valve body (14) are in the same axial direction, the spring seat (19) and the valve rod bearing (20) are located on the outer peripheral surface of the guide rod (17), the spring seat (19) and the valve rod bearing (20) are located on a lower groove of an inner shaft hole of the upper valve body (14), the spring seat and the valve rod bearing are in plane contact, the spring (18) is located on the outer peripheral surface of the guide rod (17), between the spring seat (19) and the valve disc (5), the valve rod nut (21) and the valve rod nut seat (22) are located on an upper groove of an inner shaft hole of the upper valve body (14), the plane contact is achieved, and the indicating sleeve (24) is located on the outer peripheral surface of the top of the upper valve body (14).
The guide rod (17) and the hand wheel (26) are coaxial, the guide rod (17) and the hand wheel (26) are connected through a square key and a key, the guide rod (17) and the hand wheel (26) are fixed with a hexagonal nut through a flat gasket, and the indicating cover (23) and the hand wheel (26) are coaxial and in plane contact.
The working principle is as follows: when the device is used, the device can be divided into three working states of two structures, namely valve straight-through installation and angle installation, and three working modes, namely full closing, full opening and partial quantitative opening, wherein the specific working conditions are as follows.
Fully opening a valve: the valve drives the guide rod (17) to move upwards by rotating the hand wheel (26) to achieve a full-open state. At the moment, the valve disc (5) is pressed downwards by the elasticity of the spring (18), so that the sealing ring (8) forms a seal with the valve seat (3). When a medium enters the valve through a flow channel of the lower valve body (1), the medium pressure extrudes the valve disc (5) and the sealing ring (8), so that the valve is opened.
And (3) fully closing the valve: the valve drives the guide rod (17) to move downwards by rotating the hand wheel (26) to achieve a full-closed state. The valve disk (5) is pressed downwards by the guide rod (17), so that the sealing ring (8) forms a seal with the valve seat (3).
The valve is partially opened quantitatively: the valve drives the guide rod (17) to move downwards for a certain distance by rotating the hand wheel (26), and when a medium enters the valve through the lower valve body (1) flow channel through the indication scale formed by the indication cover (23) and the indication sleeve (24), the medium pressure extrudes the valve disc (5) and the sealing ring (8), so that the valve is opened, and the flow regulation is realized.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
