Abstract
The utility model relates to a hand-press valve. A pressure handle bolt which is an improvement on the prior art is disclosed to overcome the defects of high possibility of water seepage, large operation resistance force, fast abrasion, and short service life of valves in similar class. A valve core which is composed of a valve core rod, a seal ring, a sealing pressure pad, a positioning slider is arranged between the front and the back two pressure sealing caps, penetrating through the valve body. The combined working part of the front pressure sealing cap and the handle is made into spherical surface, and thereby, the inventing purposes of no leakage, little resistance, and long service life are achieved.
Description
The utility model relates to the valve that uses on a kind of building industry, relates in particular to a kind of valve of hand-operated.
The valve of present commercially available hand-operated is by valve body, last lower cover, and spring, spool and handle are formed.Use often because of spool easily leaks, resistance is big during operating grip, and handle and loam cake abrasion are serious, and damaged condition happens occasionally.
The purpose of this utility model is to provide a kind of keying flexible, ne-leakage, long-life a kind of Pressure handle bolt.
The purpose of this utility model is achieved in that promptly and is having now by valve body, glue bowl pressure ring, and the glue bowl is on the basis of the Pressure handle bolt that handle and spring are formed, between back envelope pressure cap and preceding envelope pressure cap.In valve body, be provided with by the sliding mother in valve core rod, seal ring, seal ring pressure pad and location, form a kind of spool by mechanical connection manner, one end of valve core rod is inserted in the center hole of back envelope pressure cap, the other end penetrates in the valve body ante-chamber, the part that the top passes the glue bowl is connected with the conduction pressure cap, sinks at the handling portion of preceding envelope pressure cap interdependent therewith.In addition, valve core rod left side section has for seal ring the fastening spacing baffle ring of seal ring pressure pad; Preceding envelope pressure cap and handle binding site all are made as sphere; Back envelope pressure cap has for the center hole of valve core rod location and the ring casing of spring location.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of a kind of Pressure handle bolt of the utility model.
As shown in Figure 1, in valve body (1), glue bowl pressure ring (3), glue bowl (4) on the basis of the Pressure handle bolt that handle (6) and spring (10) are formed, has carried out technological improvement.Promptly between back envelope pressure cap (11) and preceding envelope pressure cap (2), in valve body (1), be provided with by valve core rod (12), seal ring (8), sealed pressure pad (9) and location sliding female (7) form a kind of spool by mechanical connection manner.One end of valve core rod (12) is inserted in the center hole (a) of back envelope pressure cap (11), the other end penetrates in valve body (1) ante-chamber (b), the branch that the top passes glue bowl (4) is connected with conduction pressure cap (5), sink in handle (6) branch of preceding envelope pressure cap (2) interdependent therewith, loosening for preventing seal ring (8) and seal ring pressure pad (9), section is provided with shelves rings (c) on the left side of valve core rod (12), friction for envelope pressure cap (2) and its binding site of handle (6) before reducing, all make sphere (d.e), for preventing valve core rod (12) moving, misplace under the quiet situation, back envelope pressure cap (11) has the ring casing (f) for the center hole (a) of valve core rod (12) location and spring (10) location, thereby realizes manual dexterity, ne-leakage, the goal of the invention of long service life.
The utility model has following advantage compared to existing technology:
1, because spool is by valve core rod, sealing ring, sealed pressure pad and location Sliding female the composition, and the one end is inserted in the centre bore of rear envelope pressure cap, the other end is inserted In the valve body ante-chamber, thereby overcome the disadvantage that dislocation is leaked.
2, because fastening one of valve core rod right-hand member conducts pressure cap, thereby make sealing Effect improves.
3, the position because preceding envelope pressure cap and handle combine is spherical working surface, so promptly reaches the operation light and flexible, reduces friction, and can increase the service life again.
Claims (4)
1, a kind of by valve body (1), glue bowl pressure ring (3), glue bowl (4), the Pressure handle bolt that handle (6) and spring (10) are formed, it is characterized in that between back envelope pressure cap (11) and preceding envelope pressure cap (2), in valve body (1), be provided with by valve core rod (12) seal ring (8), seal ring pressure pad (9) and location sliding female (7), pass through mechanical connection manner, form a kind of spool, one end of valve core rod (12) is inserted in the center hole (a) of seal pressure cap (1), the other end penetrates in valve body (1) ante-chamber (b), the part that the top passes glue bowl (4) is connected with conduction pressure cap (5), sinks in handle (6) part of preceding envelope pressure cap (2) interdependent therewith.
2, a kind of Pressure handle bolt according to claim 1 is characterized in that said valve core rod (12), and its left side section has for seal ring (8) seal ring pressure pad (9) fastening spacing baffle rings (e).
3, a kind of Pressure handle bolt according to claim 1 is characterized in that said preceding envelope pressure cap (2) and its binding site of handle (6) are sphere (d.e).
4, a kind of Pressure handle bolt according to claim 1 is characterized in that said back envelope pressure cap (11) has for the center hole (a) of valve core rod (12) location and the ring casing (f) of spring (10) location.
