Abstract
The utility model relates to a consequent flow-stop union type lever valve, which is composed of a main body, a valve core and a lever driving part. The utility model adopts consequent flow stop, needs not to change the flow direction of media, uses the main body which is a union integral body, and enlarges the inlet inner diameter of the media. The switching part of the lever valve adopts dynamic fit and has the advantages of small abrasion and good sealing effect, and a lever is used as the switching member which has the advantages of low cost long service life and good part interchangeability. Due to the adoption of the union integral body, the utility model has the characteristics of convenient installation and wide material source, and the phenomenon of cheating on government contracts in construction is avoided.
Description
The utility model relates to a kind of industrial used shutoff valve.
Existing stop valve, general valve body is to be enclosed in the middle of the pipeline, the flow of controlling plumbing fixtures medium.Controlling method is in valve body, it at first is structure with low in and high out, change direct current for become 90 ° the flow direction with direct current after, open and close are carried out in the axial motion that is provided with one group of screw thread rotation movement means generation under the cover sealing configuration in the top, and the polished rod on screw thread top partly is to work under the sealing configuration of tight lock.Valve is installed on the pipeline of sealing, and common process is that the outlet end of pipeline is loaded onto a loose joint pipe fitting, connects valve by connecting tube again, and the back continuity is by dress.
Because it is more that stop valve is used for industry, in order to guarantee its performance, structure is also complicated, and for open and close part good airproof performance, cost is often very high, and the Sealing of valve is to work under tight lock, and is fragile; And the construction of switch of valve makes the sectional area of medium import on the valve have only half of pipeline opening, thereby has weakened flow; Because of existing valve adopts the pressurization fluid stopping, to press greatly more in the medium, the fluid stopping effect is inversely proportional to, and performance is also poor more, and control piece is once damage, just can't fluid stopping, cause damage; Existing valve mechanism also easily causes the phenomenon of using inferior materials and turning out substandard goods in the construction.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of simple in structure, and it is very little to wear and tear, and is difficult for leaking the climb-flow-stop loose joint formula lever valve of long service life.
Technical solution of the present utility model is as follows:
A kind of climb-flow-stop loose joint formula lever valve, by body, spool and lever actuated are partly formed, it is characterized in that body (1) is a three-way body, front end inlet is provided with spool (2) at body (1), body (1) rear end is a valve export, in body (1) vertical suitable for reading, be provided with by lever (3), lever supporting ball (4) and and the lever actuated part formed of cap (7), and the top of lever (3) is from vertical suitable for reading the passing of body (1), spool (2) in its lower end and the body (1) links to each other, make spool (2) under the effect of lever (3), move forward and backward, the break-make of the working medium in the control body (1).
The utility model is because of adopting climb-flow-stop, need not change MEDIA FLOW to, and increase with the body of loose joint formula disjunctor, import internal diameter, its inlet annular cross-sectional area is greater than the pipe outlet internal diameter, therefore can not weaken flow, opening and closing when out of control, only be that valve is not opened in addition, can not cause the medium after out of control to run off.Opening and closing part, adopt dynamic fit, it is little to wear and tear, and good sealing effect is made opening tool with lever, and cost is low, long service life, and parts interchangeability is good.The utility model is with loose joint formula disjunctor, and is convenient by dress, extensive with material, stopped the phenomenon of using inferior materials and turning out substandard goods in the construction.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the valve rod (14) of spool of the present utility model (2) can be the mast that a cross section is a cross muscle shape, also can be the hollow tubular that a tube wall has the medium inlet, the internal diameter that their external diameter and body (1) medium enters hole (8) matches, the front end of valve rod (14) stretches out body (1) medium and enters hole (8) and be connected with its diameter enters hole (8) greater than medium seal face (9), the rear surface of sealing end face (9) just is against body (1) medium and advances on the seal washer of locating in hole (8) (10), the rear end of valve rod (14) has through hole (11), it is positioned at the corresponding vertical position suitable for reading of body (1), and the through hole (11) of valve rod (14) rear end is just passed in the lower end of the lever (3) in the lever actuated part.Lever (3) and lever supporting ball (4) in the lever actuated part are an integral body, lever supporting ball (4) is in the centre, the upper and lower lever (3) that is connected with, and lever supporting ball (4) is positioned at the vertical suitable for reading of body (1), the lower surface of this lever supporting ball (4) flexibly connects by the vertical lower seal suitable for reading with body (1) of lower peripheral surface seal washer (6), the upper surface of lever supporting ball (4) is provided with spacing shim (5) and is pushed down by the also cap (7) that the vertical top suitable for reading of body (1) links to each other, and makes lever (3) to move forward and backward in body (1).The front end outer wall of body (1) is provided with outside thread, and it and seam spare (12) and loose joint and cap (13) are combined into the loose joint body, links to each other with the outlet with the working medium pipe, and the medium that can enlarge body (1) simultaneously again enters hole (8).
The utility model climb-flow-stop loose joint formula lever valve is applicable to multiple medium, not only can be used as gas stop valve, also can be used as the liquid stop valve.The loose joint body of its body (1) front end links to each other with the outlet of medium supply tube during use, and body (1) back outlet links to each other with the import of user pipe.In use, adopt dynamic seal (packing), so when closing and cap (7) should be loosening state, at this moment, shifting lever (3) to MEDIA FLOW to direction firmly, lever supporting ball (4) is made fulcrum, and make sphere and roll, interlock lever (3) is in body (1), valve rod (14) is stirred in through hole (11) lining of spool (2), its contrary MEDIA FLOW is moved to doing to open, and seal face (9) leaves seal washer (10), and medium can enter body (1) inner chamber in the supply tube in the seal face of opening gradually (9) flows into poor hole, then flow to the lower end user pipe, big more with opening, pressure was big more in lower peripheral surface seal washer (6) bore, and at this moment matched with opening degree, gradually lock and cap (7), to guarantee sealing effect, lever (3) is firmly tightened and cap (7) after opening and putting in place, at this moment and cap (7) the lever supporting ball (4) that will go up sphere spacing shim (5) lower peripheral surface seal washer (6) and centre be in the fixed lock state, lever supporting ball (4) is fixed, promptly finished breakdown action.When doing closing motion, slowly loosening earlier and cap (7), under interior pressure effect, seal face (9) is made closing motion to seal washer (10), and interior pressure is big more, and closure is good more, and the closing force size is directly proportional with pressure condition in the reality.
The utility model precise structure is reasonable, and it is little significantly to wear and tear, and has improved the life-span of valve, makes the better tightness of valve.
