Description

Improvement of the structure of the opening and closing valve

This creation is about "a structural improvement of the opening and closing valve", especially an opening and closing valve structure that can be used to control the opening and closing of fluid in a pipe.

According to the conventional open-close valve (50), as shown in the eighth figure, it comprises: a valve body (51), a valve core (52), a lock screw (53) and a handle (54). Wherein, a valve chamber (511) is provided in the center of the valve body (51), the valve chamber (511) is for providing the valve core (52) to be placed, and the valve body (51) is in the valve chamber ( a first tube portion (512) is protruded from one side of the 511), and a second tube portion (513) is protruded from the other side, by the first tube portion (512), the valve chamber (511) and the first portion The phase connection of the second pipe portion (513) is turned on, and the valve core (52) is rotated by the handle (54) in the valve chamber (511) to allow the middle hole of the valve core (52) ( 521) being aligned or offset with the first tube portion (512) and the second tube portion (513), and can be used to control fluid opening and closing from the first tube portion (512), The outer surface of the valve body (51) is formed with a convex neck (514), and the convex neck (514) is provided with a radial through hole (515) which is consistently inserted into the valve chamber (511), and the radial through hole (515) is Used to provide the valve core (52) into the valve chamber (511), so that the valve stem (522) protruding from the top surface of the valve core (52) can also pass through the radial through hole (515). Out And through the locking screw (53), so that the locking screw (53) screwed smoothly after the upper convex neck (514), then the valve stem (522) The handle (54) is connected, and the outer sleeve of the valve core (52) is provided with a washer (55).

However, the conventional structure as described above still has the following problems in practical applications: (1) The gasket (55) placed on the valve core (52) alone cannot effectively prevent leakage. The opening and closing valve (50) still leaks from the lock screw (53) because the pressure of the internal fluid is too large; (2) the opening and closing valve (50) cannot be regulated, so when the opening and closing is performed When the valve (50) is to be opened from the fully closed state, the valve core (52) is acted on the valve core (52) which is not electrically connected to the valve body (51) because of the internal strong pressure. 52) Those who need to apply greater force between the turning paths that are opened.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional opening and closing valves is indeed the goal of the relevant industry to develop and research. The present creator has the idea of thinking and creation, and has many years of experience. The design, the multi-party discussion and trial sample test, and many corrections and improvements, is the launch of this creation.

The conventional opening and closing valve can not effectively prevent leakage, and it is difficult to open from the fully closed state, which is the technical problem to be solved.

The present invention provides an improved structure of an opening and closing valve, comprising: a valve body, a valve core, a sealing member and a handle, wherein a valve chamber is disposed in the center of the valve body, and the valve chamber is used to provide the a valve core is inserted, and the valve body has a first pipe portion protruding from one side of the valve chamber and a second pipe portion protruding from the other side, wherein the first pipe portion, the valve chamber and the first portion The phase connection of the two pipe portions is turned on, and the valve core is rotated by the handle in the valve chamber, so that the middle hole of the valve core and the first pipe portion and the second pipe portion are aligned or mutually The misalignment can be used to control the opening and closing of the fluid fed from the first tube portion, and the valve body is formed with a convex neck on the outer circumference of the valve body, and the convex neck is provided with a radial perforation that is consistently inserted into the valve chamber. The perforation is for providing the valve core into the valve chamber, so that the valve stem extending from the top surface of the valve core can also pass through the radial perforation, so that the top end of the valve stem can be further worn. After the sealing member, the handle is connected by the valve stem, and the first perforated wall is provided on the wall of the radially perforated hole, and the valve core has a cap-shaped body with an opening facing downward, and the outer periphery is provided Having a central bore extending through the body and sleeved with at least one leak-proof gasket, the closed surface above the body extending from the valve stem, in the middle A bypass groove extending in the same direction of rotation is connected to at least one of the hole edges of the two ends, and a sleeve portion is provided at the center of the sealing member for providing the valve stem for laying, and the inner wall of the sleeve portion has a step The edge and the outer circumference are provided with a ring groove, and the step edge and the ring groove respectively provide at least one first leakage preventing gasket and at least one second leakage preventing gasket to be embedded after the sleeve, so that the sealing member can be blocked inside and outside Stopping the leak, and the outer circumference of the sleeve portion is further connected with a disc body, and the circumference of the disc body is provided with a second thread segment, after the second thread segment passes through the sleeve portion at the top end of the valve stem, The first thread segment of the valve body is screwed so that the valve body can be surely restrained in the valve chamber by the sealing member, thereby obtaining an improved structure of the opening and closing valve.

The present invention provides an improvement of the structure of the opening and closing valve, which utilizes the installation of the first leakage preventing gasket, the second leakage preventing gasket and the leakage preventing gasket to generate multiple leakage preventing effects, and avoids the opening and closing valve due to internal fluid If the pressure is too large, there is a situation in which leakage occurs from the sealing member, and since the opening and closing valve is opened from the fully closed state, the bypass is first performed in the initial stage in which the spool is rotated. The groove provides a small flow of fluid to pass through, and the design can effectively relieve pressure at the initial stage of the rotation, thereby preventing the internal strong pressure from acting on the valve core not forming a conduction with the valve body, and the valve core is The entire rotation path needs to be given to a large force.
