The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of sand setting formula washing well ball-and-seat that is applicable to high angle hole; Comprise the top connection and the body that connect successively from top to bottom; Said body is the tubular that is provided with back cover; Said top connection top is provided with supporting positive cover, and its generatrix direction of sidewall upper edge of said supporting positive cover is provided with the sand setting hole; Be provided with the valve rod that is tightly connected with it in the said upper part of body; Said valve rod comprises the body of rod and the valve seat that is integrally formed, and the said body of rod is installed in the said supporting positive cover, and said valve base sealing is connected on the said body; Be set with spring on the said body of rod, said spring clip is pressed between said supporting positive cover and the said valve seat; Said body is a bridge architecture, and its its generatrix direction of sidewall upper edge is provided with the feed liquor side opening of crescent sand setting passage and symmetric arrangement, and said feed liquor side opening is positioned at said upper part of body.
Be provided with two seals between said valve seat and the said body; Be sealed into the face contact seal that is positioned at said body upper end together; Another road is sealed into the double T packing_seal that is positioned at said contact seal below, and said double T packing is arranged between pressure ring and the said body, and said pressure ring is sleeved on the said valve seat; Be provided with pressure cap below the said pressure ring, said pressure cap is threaded on the said valve seat.
The sealing contact surface of said body upper end is provided with overlay cladding.
Said sand setting hole is a plurality of, and all said sand setting holes are Crossed Circle and arrange on the sidewall cross section of said supporting positive cover.
Advantage and the good effect that the utlity model has are: the stem structure that adopts the body of rod, valve seat to be integrally formed, the body of rod are used for guiding, are used with supporting positive cover, are applicable to high angle hole, have desilting and backwash passage, and be safe and reliable; Valve seat adopts double containment to cooperate with body, and reliability is higher; Simultaneously the sand setting channel outlet is positioned at the body bottom, and the sealing of valve seat and body is positioned at body top, can prevent that desilting from getting into sealing surface, perhaps buries the ball-and-seat valve seat and causes the ball-and-seat inefficacy.And the utility model compactness rational in infrastructure, easy to use.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Fig. 3, a kind of sand setting formula washing well ball-and-seat that is applicable to high angle hole comprises from top to bottom the top connection 1 and body 7 that connect successively, and said body 7 is provided with the tubular of back cover for the bottom,
Said top connection 1 top is provided with supporting positive cover 1-1, and its generatrix direction of sidewall upper edge of said supporting positive cover is provided with a plurality of sand settings hole 1-1-1; All said sand setting hole 1-1-1 are Crossed Circle and arrange that the sand setting aisle spare is big on the sidewall cross section of said supporting positive cover 1-1.
Be provided with the valve rod 3 that is tightly connected with it in the top of said body 7;
Said valve rod 3 comprises body of rod 3-1 and the valve seat 3-2 that is integrally formed, and said body of rod 3-1 is installed in the said supporting positive cover 1-1, and said valve seat 3-2 is sealedly connected on the said body 7;
Be set with spring 2 on the said body of rod, said spring 2 crampings are between said supporting positive cover 1-1 and said valve seat 3-2; Cooperate supporting positive cover 1-1 to accomplish radial location, prevent lateral tilt.
Said body 7 is a bridge architecture, and the body sidewall is provided with the backwash liquor feed liquor side opening 7-2 of crescent sand setting passage 7-1 parallel with its bus and symmetric arrangement, and said feed liquor side opening 7-2 is positioned at the top of said body 7.
The main channel on body 7 tops is the seal channel of valve seat 3-2, and its upper end sealing contact surface is provided with overlay cladding, contacts the location sealing with valve seat 3-2 face through overlay cladding; Secondary seal is carried out through double T packing 4 in body 7 main channels and valve seat 3-2 bottom; The double T packing is arranged between pressure ring 5 and the said body 7; Said pressure ring 5 is sleeved on the said valve seat 7, is provided with pressure cap 6 below the said pressure ring 5, and said pressure cap 6 is threaded on the said valve seat 3-2.Sealing ring adopts the double T structure, prevents conventional seals structure stress deformation, rolls, and causes seal failure.
The operating principle of the utility model:
During ordinary production, valve rod 3 and the sealing of body 7 main channels are realized the single current function, and sand setting passage 7-1 lower end can connect oil pipe 9, and oil pipe can connect circle for 9 times and block up 8, carries out sand setting and handles; During anti-flushing well, liquid gets into from body 7 symmetrical side opening 7-2, and water pressure pushing valve rod 3 breaks away from sealing contact surface and moves upward, and forms flow channels, and anti-circulation well cleanup makes progress.For preventing that double T packing 4 from coming off when the anti-flushing well, adopt pressure cap 6 structures to fix.
