Abstract
The utility model relates to a self-sealing valve. An upper sealing assembly (6) is screwed on a body (1). A threaded rod (7) is positioned in the upper sealing assembly, and is matched with the upper sealing assembly. A wrench (8) is positioned on the upper end of the threaded rod. A valve seat body (9) is positioned in the body (1), and forms a two-way valve seat body with a valve seat in the body. The two-way valve seats of the two-way valve seat body are corresponding to each other. A valve head of a valve core (5) is positioned in a lower valve cavity of the two-way valve seat body. The valve rod and a guide groove on the lower part of the threaded rod are in the clearance fit. A seal gasket I (2) is positioned on a valve seat in the body. A seal gasket II (4) is also positioned on a valve seat body. The utility model has the advantages of novel, peculiar and simple structure design, reliable operation, and long service life.
Description
The utility model belongs to valve and makes the field.
Background technique of the present utility model: present most widely used water tap, on structural design, all adopt and force sealing means, the direction that flows out from water blocks this sealing means of osculum at first makes sealing gasket bear the pressure of water, the sub-transferee is the pressure that water is not leaked that applies, sealing gasket bears extra pressure, damages easily.
Purpose of design of the present utility model: avoid the deficiencies in the prior art part, design a kind of self-sealed valve (water tap) with self-sealing function.
Design proposal of the present utility model: utilizing the one-way valve principle, on the basis of existing technology, is the automatic type sealing with the compulsory type Seal Design.Its organization plan: self-sealed valve, last sealing assembly (6) is screwed on the body (1), screw rod (7) is positioned at sealing assembly and supporting with it, spanner (8) is positioned at the upper end of screw rod, valve body (9) is arranged in body (1) and constitutes the two-way valve pedestal with the valve seat of body, the two-way valve seat of two-way valve pedestal is relative, the guide groove that the valve head of spool (5) is positioned at two-way valve pedestal lower valve chamber, valve rod and screw rod bottom is Spielpassung, sealing gasket I (2) is arranged on the valve seat of body, and sealing gasket II (4) is positioned on the valve seat of valve body.The section of valve body (9) is the H type and is provided with valve seat in the middle.The top of valve body (9) has pod apertures.The valve head of spool (5) is valve port among the frustoconic shape sealing structure pad II (4) and the frustoconic shape valve head of spool is complementary.Sealing gasket I has valve port on (2).
The utility model compared with prior art has structural design novelty, uniqueness, simple, reliable operation, long advantage of life-span.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1 pair of the utility model is done with narration in conjunction with the accompanying drawings.
When screw rod (7) was in topmost, spool (5) was not subjected to axial force.When passing to the water of pressure in the body (1), current are located the closed hole (valve seat) that spool rushes at valve body (9), automatically water seal are lived, and the pressure of water is big more, and the suffered pressure of spool is also big more, and water seal is dead.Turn screw rod, promote valve core movement, water flows out from the hole, realizes the open and close function.Continue to twist screw rod,, the large end face of spool is contacted with the water inlet end face, water can be sealed as existing water tap again to the water intake end motion.When using one-way valve, sealing gasket is stressed stressed littler than existing water tap sealing gasket, thereby longer than the existing water tap life-span; When one-way valve damages, can be used as existing faucet valve and use, therefore, the life-span exceeds one times at least than existing water tap.
Claims (6)
