Description
Technical field
The present invention relates to ball valve sealing field, in particular to a kind of processing technologys of U-shaped elastic hard sealed ball valve valve seat.
Background technique
Ball valve is one of most common accessory in pipeline transmission field, and the spherical valve core of through-hole is provided in runner
And two pieces of valve seats in a ring, and so that two valve seats is located at the two sides of spherical valve core, therefore rotation spherical valve seat can be passed through
The positional relationship of through-hole and valve seat is adjusted, to control the opening and closing of runner.
It is a kind of reliable and common seal means that wherein valve seat and spherical valve core, which use hard sealing structure,.By metal material
Valve seat and spherical valve core directly offset, and using compressed spring is arranged between valve seat and valve body, by compressed spring by valve
Seat is resetted towards spherical valve core direction, is sealed so that valve seat is closely realized with spherical valve core.
However aforesaid way with the following drawback that: first, return unit is used as using compressed spring, and when compressed spring
The working condition in compression is carved to use after a certain period of time easily since compressed spring service life itself is shorter
Failure, so that valve seat and spherical valve core depressurization cooperate, so that runner is revealed；Second, due to the fluid media (medium) of transport
In adulterate the biggish solid impurity of some particles sometimes, therefore solid impurity has certain probability to enter pressure in transmission process
In contracting spring, so that not only Compression and Expansion is inconvenient for compressed spring, and easily interact with solid impurity, so that compressed spring
It is destroyed.
To solve the above-mentioned problems, as shown in Fig. 2, devising one kind can be bonded with spherical valve core, but can simultaneously itself
Elastic force is provided, U-shaped elastic hard sealed ball valve valve seat of the valve seat squeezed tight between valve body and spherical valve core is made comprising cyclization
The valve seat body 1 ' of shape setting, 1 ' periphery of valve seat body offer the U-type groove 11 ' of a U-shaped profile radially inward, and
Inner circumferential and axial left and right sides are in setting is smoothly connected, so that left and right sides are in U-shape with inner circumferential, in addition, valve seat body 1 '
It is provided with welding position 12 ' at circumferential one, so that valve seat body 1 ' constitutes the closure ring body of a sealing.
Summary of the invention
In view of the deficienciess of the prior art, the first purpose of this invention is to provide a kind of U-shaped elastic hard sealing ball
The processing technology of valve base, the technical scheme comprises the following steps:

It is dynamic to be set to rack, and the second one-tenth U deflector roll periphery is recessed inwardly and is provided with U compatible with the first U-shaped lobe shape size
Type recessed portion, the cyclization deflector roll is rotatably dispose in rack, and cyclic deflector roll periphery outwardly protrudes and is provided with and the first U-shaped protrusion
The identical second U-shaped protrusion of portion's shape size, the cyclization deflector roll, the first one-tenth U deflector roll and the second one-tenth U deflector roll are axially set in parallel
It sets, and the first one-tenth U deflector roll, cyclic deflector roll are symmetrically arranged in the second one-tenth U deflector roll two sides, so that three center is in isosceles
Triangle setting, the first U-shaped protrusion and the second U-shaped protrusion extend partially into U-shaped recessed portion, and the feed member is set
Be equipped with width, thickness guide rail compatible with smooth steel plate, and the orbital direction of guide rail perpendicular to the first one-tenth U deflector roll axial direction,
And with the first U-shaped tangent setting in protrusion periphery.
The multistage spiral coil of screw cylindrical blank is cut into the spiral coil that radian is 350-360 ° by step 2, and will
Two of spiral coil cut section and are mutually aligned shaping；
Step 3 cuts section for two of spiral coil and is welded by solder, and the U-shaped elasticity for constituting generally circular ring shape is hard
Seal ball-valve valve seat semi-finished product；
Step 4, Re-stress heat treatment, specifically: U-shaped elastic hard sealed ball valve valve seat semi-finished product are heated to 960
DEG C, keep the temperature 17 hours, natural cooling；
Step 5, crystal enhancing heat treatment, specifically: it will be through step 4 treated U-shaped elastic hard sealed ball valve valve seat
