The angle check valve is installed on the pipeline, the valve cover is in the vertical upward direction, the valve cover falls off, the human body cannot be injured, and the valve is safe to use.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a front cross-sectional view of an embodiment of the present invention;
in figure 1, a valve cover 1, an isolation sleeve 2, a valve seat 3, a valve clack 4, a spring 5, a guide seat 6, a valve body 7, a water inlet A, a water outlet B, a middle hole C and a flow passage hole D.
Detailed Description
In fig. 1, an angle type high-pressure check valve is composed of a valve body (7), a valve cover (1), a guide seat (6), a valve clack (4), a valve seat (3), a spring (5) and an isolating sleeve (2), wherein the valve body (7) is provided with a water inlet (A) and a water outlet (B), the lower end of the valve body (7) is provided with the guide seat (6), the spring (5) is arranged in the guide seat (6), the valve clack (4) is arranged at the upper end of the spring (5), the valve seat (3) is arranged at the upper end of the valve clack (4), the isolating sleeve (2) is arranged at the upper end of the valve seat (3), and the valve. The valve clack (4) is arranged at the lower end of the valve seat (3), the upper end of the valve seat (3) is provided with the isolating sleeve (2), the isolating sleeve (2) is provided with a middle hole (C), the middle side surface of the isolating sleeve (2) is provided with a flow passage hole (D), and the flow passage hole (D) is communicated with the water inlet (A) of the valve body (7).
The water inlet (A) is arranged at the upper part of the valve body (7), and the water outlet (B) is arranged at the lower end of the valve body (7).
The utility model discloses an installation direction: the utility model discloses it is the high state of advancing low when installing high-pressure line, water inlet (A) on the upper portion of valve body (7), delivery port (B) are at the lower extreme of valve body (7), and valve gap (1) is in perpendicular direction up when the valve is installed at high-pressure line. Compared with the existing high-pressure angle check valve with low inlet and high outlet, the water inlet is arranged at the lower end of the valve body, the water outlet is arranged at the upper part of the valve body, and the valve cover is arranged in the horizontal direction when the valve is arranged on a high-pressure pipeline.
The utility model discloses a theory of operation is: when medium pressure exists in the water inlet (A), the valve clack (4) is pushed by the medium pressure to compress the spring (5) to move downwards, a gap is formed between the valve seat (3) and the contact surface of the valve clack (4) to form a medium flow passage opening, a medium reaches the flow passage hole (D) and the middle hole (C) of the isolation sleeve (2) from the water inlet (A) of the valve body (7), and flows to the water outlet (B) of the valve body (7) from the medium flow passage opening formed by the valve seat and the valve clack to output the valve body.
When the water inlet (A) stops feeding water, the valve clack (4) moves upwards under the action of the elastic force of the spring (5) and the return water pressure, the valve seat (3) is in close contact with the sealing surface of the valve clack (4) to realize sealing, and the medium is automatically prevented from reversely flowing.
