Abstract
The invention discloses a self-cleaning ball valve, which comprises a valve body, wherein a valve base and a ball spool or semi-ball spool are arranged in the valve body; the ball pool or semi-ball spool is connected with a valve rod which penetrates outside the valve body; and a sealing device is arranged between the valve rod and the valve body. The self-cleaning ball valve is characterized in that: the ball pool or semi-ball spool comprises a guide-in section and a sealing section of the valve base; a hole is formed on the guide-in section along the spherical surface; and a solid lubricating medium is embedded in the hole. When fine solid particles appear in the medium, the medium passes through the guide-in section of the spool first before entering the sealing surface between the spool and the valve base. The embedded material functions as an absorbent due to low hardness and certain plasticity, the particles carried by the medium are filled in pores of the embedded materials, and thus, the ball spool or the valve base are prevented from scratching when the solid particles are brought to the sealing surface between the spool and the valve base. Therefore, the service life of the valve is prolonged.
Description
The invention belongs to valve, be specifically related to a kind of ball valve.
Background technique
Existing ball valve, semispherical valve and eccentric half-ball valve are to rely on sealing between ball valve core or hemisphere spool and the valve seat to realize the keying of valve.There is friction in spool in opening-closing process and between the valve seat.If when having the tiny solid particle in the swiftly flowing medium (as: steam), very easily bring between spool and the valve seat with the ball core of motion, cause spool to scratch.After in a single day spool face had cut, the easier fine particle of bringing into caused the spool face cut to increase.And so forth, the very fast inefficacy of the sealing between spool and the valve seat causes valve to produce too early leaking and scraps.Existing solution is in the MEDIA FLOW inlet side of valve filtrating equipment to be set, complex structure like this, and the valve pipe connection device is many, the cost height.Second workaround is to concentrate on to seek on the new high-abrasive material, and it is wear-resisting that expectation improves spool, the scratch resistance ability.But effect is also not obvious, and manufacture cost significantly raises.
Summary of the invention
The object of the present invention is to provide a kind of self-cleaning ball valve that can adsorb (existing in the flowing medium) little solid particle, to overcome above-mentioned defective of the prior art.
Technological scheme of the present invention is: it comprises valve body, valve seat is set in the valve body, ball valve core or hemisphere spool, ball valve core or hemisphere spool connect valve rod, valve rod passes valve body, establishes seal arrangement between valve rod and the valve body, it is characterized in that ball valve core or hemisphere spool comprise the introduction segment face and with the seal section face of valve seat, introduction segment face upper edge sphere is offered porose, is inlaid with the solid lubrication material in the hole.
The hole that described introduction segment face upper edge sphere is offered be longshore current road circle distribution on the sphere of introduction segment face, the hole has two rows at least.
Described two adjacent rounds shift to install.
Described hole is located on the introduction segment face of ball valve core seal section face both sides or on the introduction segment face of a side.
It is the hemisphere spool, and described hole is located on the side introduction segment face of semispherical valve seal spool section face.
Described hemisphere spool is eccentric the setting.
The present invention embeds solid lubricant in the facial position of the introduction segment of ball valve core or hemisphere spool, boring.According to different media and serviceability temperature etc., the material of embedding can be graphite carbon rod or slicker solder low-melting alloy.When ball valve core or hemisphere valve core movement, insert material serves as oiling agent, reduces the frictional force between spool and the valve seat greatly, the mechanical wear when reducing the interaction of spool and valve seat.If when occurring the tiny solid particle in the medium, at first to just can enter the sealing surface of spool and valve seat through the introduction segment face of spool.Insert material has certain plasticity because hardness is low, can play the effect of sorbent, and the particle that medium is brought into can be filled among the hole of insert material.Prevent that like this sealing surface that solid particle is brought between spool and the valve seat from scratching ball valve core or valve seat, thereby prolonged the working life of valve.It also is quite simple with the existing mechanical manufacturing process ball valve core or hemisphere spool being changed a social system, and low production cost has better solved the wearing and tearing and the scuffing problem of spheroid in the ball valve.Ball valve of the present invention can be that the ball valve of ball valve core also can be the semispherical valve of hemisphere spool, eccentric half-ball valve.More be applicable to the ball valve of ball valve core.

Embodiment
Present embodiment is illustrated with the ball valve of ball valve core, and the valve core structure of semispherical valve and eccentric half-ball valve is the hemisphere spool, and the hole is located at a side of semispherical valve seal spool section face.
As shown in Figure 1, valve body is formed by connecting by nut bolt 3 by left valve barrel 1 and right valve barrel 2, is provided with sealing gasket 4 between left valve barrel 1 and the right valve barrel 2.Be provided with both sides valve seat 5 in left valve barrel 1 and the right valve barrel 2, ball valve core 6 is located between two valve seats 5.Ball valve core 6 tops connect valve rod 7, and valve rod passes valve body, and and valve body between seal.Establish seal arrangement in the present embodiment between valve rod and the valve body and comprise the stuffing box packing 8 (seal ring, seal ring etc.) that is provided with between valve rod and the valve body, stuffing box packing pressure ring 9, stuffing box packing 8 is provided with fireproof pad 10; Stuffing box packing pressure ring 9 is provided with butterfly spring 11 and loosens and covers 12.
Be not limited to foregoing description for the sealing configuration between valve body, valve rod and valve body and the valve rod, the structure of existing ball valve, semispherical valve and eccentric half-ball valve all is suitable for.Core of the present invention is on spool.
Shown in Fig. 2,3, ball valve core 6 comprise introduction segment face 13 and with the seal section face 14 of valve seat.When introduction segment face described here and seal section face are valve closing, the contact seal face punishment circle of ball valve core and valve seat, this moment, relative with medium sphere section was introduction segment face (the ball valve core segment outside the valve seat), and the ball valve core section within the valve seat is a seal section face 14.The introduction segment face of semispherical valve and the seal section face also be like this.It is porose 15 that introduction segment face 13 upper edge spheres are offered, hole 15 be longshore current road circle distribution on the sphere of introduction segment face, the hole has two rows at least, is 2 rounds 15 in the present embodiment, two adjacent rounds shift to install.The end face diameter in hole 15 is less than the bottom surface diameter.(the end face diameter that can also be hole 15 equals the bottom surface diameter).Be inlaid with solid lubrication material 16 in each hole 15, solid lubrication material 16 is graphite carbon rod or slicker solder low-melting alloy.Graphite carbon rod or slicker solder low-melting alloy stick on the hole wall.The present embodiment mesopore is located on the introduction segment face of both sides of ball valve core seal section face; Solid lubrication material 16 is graphite carbon rods.
