Abstract
The utility model discloses a valve sleeve structure of a grouting pump for slurry suction and discharge, in particular to a plug-pin type valve sleeve for the slurry suction and the discharge. The valve sleeve comprises a valve sleeve body for the slurry suction and the discharge and a valve base connected with the lower end of the valve sleeve body for the slurry suction and the discharge, wherein the upper end of the valve sleeve body for the slurry suction and the discharge is provided with a slurry outlet, the lower end of the valve base is provided with a slurry inlet, a valve ball is arranged in an inner cavity of the valve sleeve body for the slurry suction and the discharge, the valve ball can seal the slurry inlet in a one-way mode, the upper portion of the inner cavity of the valve sleeve body for the slurry suction and the discharge is provided with a plug-pin inserted transversely, and the plug-pin is located between the slurry outlet and the valve ball. By means of the structure, the plug-pin type valve sleeve is simple and convenient to process, high in processing efficiency and low in processing cost due to the fact that the valve sleeve for the slurry suction and the discharge is integrally formed. Holes are directly drilled in the side wall of the valve sleeve for the slurry suction, the discharge and the plug-pin is inserted, and therefore the valve ball can be limited. Only the plug-pin portion needs to be welded and sealed, so welding quantity is small, and normal work of the grouting pump can be ensured.
Description
Technical field
The utility model relates to a kind of valve pocket structure of grouting pump suction slurry, specifically a kind of bolt-type suction slurry valve pocket.
Background technique
The valve body that has the grouting pump suction pulp-expelling valve of unidirectional fluid function in the prior art generally is divided into interconnective valve pocket and valve seat two-part, and the valve pocket upper end arranges the slurries outlet, and the valve seat lower end arranges the slurries entrance, in the valve pocket inner chamber valve ball is set.Valve pocket upper end slurries exit portion is shut when working in order to prevent the valve ball in the grouting pump suction slurry valve pocket, affect the grouting pump normal operation, therefore usually to limit structure be set in the slurries outlet port, common limit structure is to be milled with criss-cross groove at the bottom end face that slurries export, like this when slurries flow out, although valve ball can stop slurries outlet lower end, slurries still can enter into proper flow in the slurries outlet by criss-cross groove.Adopt such limit structure, on the one hand owing to carry out groove milling at the bottom of upper valve sleeve end face, amount of finish is large, work efficiency is low, need on the other hand valve pocket is divided into two-part, processing adopts the form of welding to connect to form an integral body more respectively, welding capacity is also very large, and work efficiency is low, cost is high.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, amount of finish is little, work efficiency is high and can guarantee the bolt-type suction slurry valve pocket of grouting pump normal operation.
In order to solve the problems of the technologies described above, bolt-type suction slurry valve pocket of the present utility model comprises a suction slurry valve pocket and is connected in the valve seat that the valve pocket lower end is starched in suction that the upper end of suction slurry valve pocket is provided with the slurries outlet, and the lower end of valve seat is provided with slurry inlet; Be mounted with valve ball in the inner chamber of suction slurry valve pocket, valve ball can the unidirectional blocking slurry inlet; Described suction slurry valve pocket inner chamber top is provided with a laterally inserted latch, and latch is between slurries outlet and valve ball.
After adopting above-mentioned structure, because suction slurry valve pocket integral body processes, process simple and convenient, work efficiency is high, processing cost is also low, it is spacing directly just can to carry out valve ball after then the sidewall boring of suction slurry valve pocket insert latch, only need latch place welded seal is got final product, welding capacity is little and can guarantee the normal operation of grouting pump.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, valve ball limit structure in the bolt-type grouting pump suction slurry valve pocket of the present utility model is described in further detail.
As shown in the figure, bolt-type suction slurry valve pocket of the present utility model comprises a suction slurry valve pocket 1 and is connected in the valve seat 2 that valve pocket 1 lower end is starched in suction that the upper end of suction slurry valve pocket 1 is provided with slurries outlet 3, and the lower end of valve seat is provided with slurry inlet 4; Be mounted with valve ball 6 in the inner chamber of suction slurry valve pocket 1, valve ball can unidirectional blocking slurry inlet 4; Described suction slurry valve pocket 1 inner chamber top is provided with a laterally inserted latch 5, and latch 5 is between slurries outlet 3 and valve ball 6.After latch 5 inserts with its end welded seal.
