Abstract
The utility model relates to a combined sealing washer, which is particularly suitable for a washing basin, the lower side of a water closet, and the upper part of the triangular valve of the point of the water inlet and outlet pipe of a water heater to mount and use. The utility model is composed of a washer, and the washer is composed of an inner washer and an outer washer. The inner washer is inserted in an annular groove on the inner wall of the outer washer, and the sectional plane of the annular groove is matched with the shape of the inner washer. The upper and lower end surface of the inner wall of the outer washer is a circular arc shape and is point-contact with the valve rod of the triangular valve, and a handle is convenient for rotating. Because the utility model is the combined sealing structure, the sealing effect is good, and service life is long.
Description
The utility model relates to a kind of seal ring.The combined type packing ring of installing below the particularly a kind of lavatory basin that is used for, toilet and on the triangle vavle at the inlet tube and outlet tube place of water heater, using.
Its seal ring of existing triangle vavle is trapezoidal packing ring, and its friction factor is big, and feel was very tight when rotation was rotated, and after service time was long, easy to wear again the causing of packing ring leaked, and increased user's trouble.
The purpose of this utility model is to provide a kind of combined type packing ring, is installed on the valve body and uses, and rotation is rotated easily, its good sealing effect, long service life.
The utility model is achieved in that combined type packing ring is made up of packing ring, and packing ring constitutes by inside and outside packing ring is compound, and inner washer embeds in the annular groove on the outer washer inwall, and annular groove cross section and inner washer shape are complementary.
Fig. 1. structural representation of the present utility model.
Fig. 2. user mode figure of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Inner washer (2) is the O RunddichtringO.
Outer washer (1) upper end is a truncated cone, and the lower end is cylindrical.There is an annular groove centre of inwall.The groove cross section is circular, is complementary with the shape of inner washer (2), and the upper and lower end surface of inwall is respectively the arc surface of symmetry.
Inner washer (2) is embedded formation combined type packing ring in the groove of outer washer (1).
During use, it is installed on the triangle vavle, embeds, be close to pad (6) on pressure cap (5) inner chamber top.And be enclosed within and have handle (3).On the valve rod (4) of pad (6), plain seal circle (8).Pressure cap (5), helmet (9) is fixed on the three way valve (7) with screw thread, and triangle vavle assembles just can be installed in the use of inlet tube and outlet tube place.
The utility model is compared with prior art: because the outer washer inner wall surface is arc surface, with valve rod be circular arc The shape contact, therefore, feel was light when handle rotated. Form combined type because being embedded with inner washer in the outer washer again Structure has dual sealing functions, so good sealing effect.
Claims (2)
1. a combined type packing ring is made up of packing ring, it is characterized in that packing ring by inside and outside packing ring (2), and (1) is formed, and inner washer (2) embeds in outer washer (1) inwall annular groove, and annular groove cross section and inner washer (2) shape is complementary.
2. seal ring according to claim 1, it is characterized in that inner washer (2) is the O RunddichtringO, outer washer (1) upper end is a truncated cone, and the lower end is cylindrical, the centre of inwall has a cross section to be circular annular groove, and the upper and lower end face surface of inwall is respectively the arc surface of symmetry.
