Abstract
The utility model discloses a pressure regulating and limiting valve which changes the rigid connection of a valve core and a valve stem into flexible connection. The valve core and the pressure adjusting valve stem are connected by a spring, a piston and a steel ball. The pretightening force of the spring is changed by the displacement of the pressure adjusting valve stem, the grouting pressure can be directly and effectively adjusted to cause the valve core to always work in an open state, and the valve core is separated from a valve seat. The utility model utilizes a force balance principle to cause the valve core to automatically and immediately adjust the opening extent of a valve according to the variation of the grouting pressure, and the utility model achieves the pressure adjusting and limiting effect to ensure the high-pressure grouting quality. The utility model has the advantages of automatic pressure adjustment, limitation and stabilization, flexible adjustment and convenient disassembly, and reduces labour intensity. The utility model can be widely suitable for the grouting equipment of every industry or trade.
Description
The utility model belongs to the filling equipment pressure regulation pressure limiting utensil field of boring.
Grouting is technical measures commonly used in the foundation treatment engineering, and grouting pressure is the key factor of control grouting quality and grouting effect.Based process to complexity adopts the high pressure grouting technology more, and amplitude improves by reason of heavy pressure, and the pressure control facility are had higher requirement.Existing stopcock, mainly be made up of taper cock and valve body, the taper cock has rectangular through-hole, rotates cock and makes alternately aligning and staggering of hole corresponding on through hole and the valve body in the cock, slurry is produced the flow resistance that varies in size, before valve, obtain corresponding pressure in the pipeline.Its deficiency is: 1. higher pressure all acts on a side of taper cock, produces very big lateral thrust, causes the stopcock control lag, malfunctioning so that inefficacy; 2. the rotation angle of taper cock and be seriously non-linear, wayward between the governor pressure; 3. grouting construction overall process, stopcock is all by manual operation, and labor intensity is big, and spirit is very nervous; 4. very easily wearing and tearing, the life-span is short.Improved modulating valve, spool is rigid the connection with the pressure regulation bar, still has regulation range little, and is insensitive, the deficiency of unreasonable structure.
Provide a kind of regulation range big, sensitivity, safe and reliable high pressure grouting pressure-regulating and pressuring-limiting valve is a purpose of this utility model.
Structure of the present utility model as shown in the figure.Accompanying drawing is the pressure-regulating and pressuring-limiting valve sectional drawing, wherein 1, bonnet; 2, pressure regulation valve rod; 3, hollow bung flange; 4, steel bowl; 5, ball; 6, axle bumper; 7, piston; 8, seal ring; 9, valve body; 10, grout outlet; 11, valve core housing; 12, spool; 13, valve seat; 14, spring; 15, rubber band; 16, hang the muscle hook up and down; 17, bottom flange; 18, tightening nut; 19, steel ball.
Characteristics of the present utility model are that spool 12 connects with pressure regulation valve rod 2 mutually by spring 14, piston 7, steel ball 19, hardening is connected to and flexibly connects, one end of spool inserts among the spring, be connected with spring, the end that piston protrudes is connected with the other end of spring, and steel ball 19 is located on the piston and is connected with regulating valve stem, works the displacement effect of transmitting, bottom flange 17 is welded with valve seat 13, cooperates spool work.
The end that spool protrudes has valve core housing (11) and spool welding, with the location spool.
The muscle hook (16) of extension is arranged on piston and the valve core housing, and rubber band (14) passes from spring center, hangs over and hangs up and down on the muscle hook, utilizes elastic force that piston, spring, spool are connected as a single entity, and during off-load, spring, spool together can be mentioned again.
Body surface at piston is equipped with seal ring 8, in case cement slurry infiltrates piston and body cavity upper half part.
Embodiment of the present utility model:
Spool is made with the rigid alloy of W-Co kind, and taper shape is when the pulp-inlet pipe bore is 0.0254m(lin), when setting pressure was 2～5MPa, spool weighed 300～600g, the high 65mm of spring, external diameter 30mm, mesopore 20mm, rigidity 6kg/mm.
According to the size of grouting setting pressure, only need to improve or reduce the rigidity of spring, to change spring and get final product, spring should guarantee the compression zone of 25mm.
Distance need 〉=spool the height of hollow nut 3 and bonnet 1.
Rubber band passes from spring center, and one hangs on the piston hook, and one hangs on the valve core housing, utilizes elastic force that piston, spring, spool are fused.When the pressure regulation bar unclamps, spring, spool together can be mentioned thoroughly off-load; When the pressure regulation valve rod compresses, do not influence camber of spring.
The grouting beginning according to setting pressure, is rotated the pressure regulation valve rod earlier, makes piston produce displacement, carries out pressure regulation; When advancing to starch, pulp-inlet pipe pressure strengthens, spool always works in the opening state of lifting off a seat, and utilizes force balance principle, spool can be changed according to grouting pressure adjust the spool aperture automatically immediately, when surpassing setting pressure, the spool aperture is along with increase, and slurries flow out from the overfall mouth, carry out the automatically pressure limiting voltage stabilizing like this, to guarantee grouting quality and effect, safe and reliable.After grouting is finished, unclamp the pressure regulation valve rod, piston drives the rubber band on the hook to top offset, spool is together mentioned off-load together with spring.
Under the effect of pressure-regulating and pressuring-limiting valve, grout hole is starched the grouting operation overall process of not inhaling slurry from suction, and grouting pressure changes little; to realize pressure stabilization function; can frequently regulate with manpower midway, alleviate labor strength greatly, play the effect of safety protection.
The utility model has the advantage of:
1. can precompute the accessible pressure of grouting, the spool aperture can be regulated under elastic force and grouting pressure effect voluntarily, and the pressure limiting pressure stabilization function is outstanding.
2. be linear relationship between piston stroke and the grouting pressure, operating characteristic is good.
3. regulate sensitivity, no control lag phenomenon.
4. change different springs, can enlarge control range.
5. spool, valve seat are used the rigid alloy material of W-Co kind instead, and be wear-resistant, long service life.
6. alleviate working strength of workers greatly.
7. dismounting and change is convenient.
The utility model can be widely used in the provisions for grouting of industries such as based process, dam, building, tunnel, mining.
