Abstract
The utility model discloses a partial limit type one-way ball valve, which has high particle pass capability, saves the equipment investment and facilitates the construction. The partial limit type one-way ball valve comprises a discharge port, an upper ball limit rod, an upper ball, a lower ball front-limit rod, a cylinder head, a lower ball, a feed port, a low ball rear-limit rod, a cylinder sleeve and a piston. The lower ball front-limit rod is arranged above the horizontal central line of the cylinder head, the lower ball rear-limit rod is arranged on the horizontal central line of the cylinder head, and the lower ball front-limit rod and the lower ball rear-limit rod are arranged rightward relatively to the front end face of the cylinder head, thereby forming a partial limit device. The utility model is used in mortar pump or concrete pump for the delivery of the mortar and the concrete.
Description
Technical field
The utility model relates to the technical field of ball-valve type mortar pump in the mortar conveying mechanism, specifically relates to a kind of limit-type partially non-return valve that is used for mortar or concrete pump.
Background technique
At present, the valve ball of the mortar on the market, concrete pump ball valve, the mode that all adopts cylinder cap middle part that position-limited lever is set limits the rising space of valve ball, to the aperture that the makes ball valve maximization of being unrealized.This situation has seriously influenced the granule size of conveying material, the suction resistance of material is also relatively large, when especially in the floor heating construction, needing to add lid layer pea gravel concreten enhancement layer, this equipment just can not satisfy usage requirement, present way is to increase a pea gravel concreten pump, causes the equipment investment expense to double.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of particle passing capacity height is provided, saves the limit-type partially non-return valve of equipment investment, easy construction.
For achieving the above object, the utility model adopts following technical proposals: limit-type partially non-return valve of the present utility model comprises discharge port, goes up the ball position-limited lever, goes up ball, ball front limit bar, cylinder cap, ball, material feeding mouth, position-limited lever, cylinder sleeve, piston behind the ball down down down.Described ball front limit bar down is arranged on the horizontal center line top of cylinder cap, position-limited lever is arranged on the horizontal center line of cylinder cap behind the described ball down, and relative this cylinder cap front-end face in position of position-limited lever moves to right behind described down ball front limit bar and the described ball down, form the spacing configuration of a kind of biasing, and make the distance of described down ball front limit pole clearance cylinder cap front-end face, and the spacing of position-limited lever behind described down ball front limit bar and the described ball down, also have position-limited lever behind the described down ball all to be slightly less than this time bulb diameter, realize the maximization of the aperture K value of ball apart from the distance of cylinder cap bottom surface.
After adopting technique scheme, the beneficial effects of the utility model are:
Because relative this cylinder cap front-end face in position of position-limited lever moves to right behind described down ball front limit bar and the described ball down, form the spacing configuration of a kind of biasing, and make the distance of described down ball front limit pole clearance cylinder cap front-end face, and the spacing of position-limited lever behind described down ball front limit bar and the described ball down, also have position-limited lever behind the described down ball all to be slightly less than this time bulb diameter, realize the maximization of the aperture K value of ball apart from the distance of cylinder cap bottom surface.This just makes the particle passing capacity of ball-valve type mortar pump improve greatly, possessed the ability of carrying general microlith, can finish the work of pea gravel concreten pump in many aspects, realized the function of dual-use, save equipment investment, improved the comfort level of construction.Effect with particle passing capacity height, saving equipment investment, easy construction.
Description of drawings
Accompanying drawing is the limit-type partially non-return valve structural representation of the utility model.
Among the figure: position-limited lever 8 cylinder sleeves 9 pistons 10 behind 7 times balls of 3 times ball front limit of ball bar, 4 cylinder caps, 5 times balls, 6 material feeding mouths on the ball position-limited lever 2 on the discharge port 1
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The structure of the limit-type partially non-return valve of the utility model comprises discharge port 1, goes up ball position-limited lever 2, goes up ball 3, ball front limit bar 4, cylinder cap 5, ball 6, material feeding mouth 7, position-limited lever 8, cylinder sleeve 9, piston 10 behind the ball down down down as shown in drawings.Described ball front limit bar 4 down is arranged on the horizontal center line top of cylinder cap 5, position-limited lever 8 is arranged on the horizontal center line of cylinder cap 5 behind the described ball down, and relative these cylinder cap 5 front-end faces in position of position-limited lever 8 move to right behind described down ball front limit bar 4 and the described ball down, form the spacing configuration of a kind of biasing, and make described ball front limit bar 4 down apart from the distance of cylinder cap 5 front-end faces, and the spacing of position-limited lever 8 behind described down ball front limit bar 4 and the described ball down, also have position-limited lever 8 behind the described down ball all to be slightly less than this play ball 6 diameters, realize the maximization of the aperture K value of ball 6 apart from the distance of cylinder cap 5 bottom surfaces.
Working procedure of the present utility model is, the piston 10 that is installed in the cylinder sleeve 9 draws back to the right, following ball 6 is opened, the maximum opening of ball 6 under the spacing realization down of position-limited lever 8 behind described ball front limit bar 4 down and the described ball down, mortar or concrete enter in the valve from material feeding mouth 7, and when piston 10 compressed left, following ball 6 was closed, last ball 3 is opened feed, finishes a charging, discharging process.
