Abstract
The utility model discloses a magnetism theftproof soft sealing gate valve, which comprises the following components: a valve body, the valve body about both ends be equipped with respectively with the inlet and the liquid outlet of valve pocket UNICOM, the upper end of valve body is fixed with the valve gap, valve rod in stretching into the valve pocket in addition on the valve gap, sealing connection between outer wall of valve rod upper end and the valve gap inner wall, valve gap and valve rod upper end are equipped with the end cover, the case is installed to the lower extreme of valve rod, the case includes inner supporting rod, the inner supporting rod overcoat is equipped with the EPDM rubber sleeve, the last end rotation of inner supporting rod closes installs anti -loosening nut, anti -loosening nut withstands EPDM rubber sleeve tip, the cladding has the neck bush of metal tube -shape in the EPDM rubber sleeve. The utility model discloses structural design is novel, can guarantee the performance of blocking of in mechanical strength and the use of case through equitable case structure, and anti -loosening nut can guarantee that liquid can not get into valve rod and case link, guarantees reliability and the fastness connected.
Description
Technical field:
This utility model relates to gate valve, particularly relates to a kind of magnetic anti-theft soft sealing gate valve.
Background technology:
Gate valve is a kind of modal keying valve, utilizes flashboard (i.e. opening and closing element, opening and closing element is called flashboard or gate in flashboard, and lock seat is called flashboard seat) connect (standard-sized sheet) or block the medium in (entirely closing) pipeline.It does not allow as use of damming, and should avoid opening flashboard trace, because the erosion of swiftly flowing medium can accelerate the damage of sealing surface in using.
There is certain defect on soft sealing gate valve valve core structure in the market, spool mechanical strength is low, in use poor with the sealing of cavity, causes that result of use is poor, and service life is short.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of magnetic anti-theft soft sealing gate valve, novel in structural design, and mechanical strength is high, good airproof performance, long service life.
The technical solution of the utility model is as follows:
Magnetic anti-theft soft sealing gate valve, including valve body, the left and right of valve body is respectively arranged at two ends with the inlet with valve pocket UNICOM and liquid outlet, the upper end of valve body is fixed with valve gap, also has the valve rod extending in valve pocket from valve gap upper end, it is tightly connected between valve rod outer wall upper end and valve gap inwall, valve gap and valve rod upper end are provided with end cap, it is characterized in that: the lower end of described valve rod is provided with spool, spool includes inner bracing piece, EPDM rubber set it is set with outside inner bracing piece, inner bracing piece upper end screws and is provided with screwed retaining ring, screwed retaining ring withstands EPDM rubber set end, the neck bush of metal tub it is coated with in described EPDM rubber set.
Described magnetic anti-theft soft sealing gate valve, it is characterized in that, described screwed retaining ring outer wall is provided with the external seal groove of annular, screwed retaining ring outer wall lower end is provided with the exterior seal ring installation step of annular, external seal groove constitutes the positioning boss of annular with exterior seal ring installation step, is arranged at intervals with multiple tracks inner seal ring mounting groove in screwed retaining ring endoporus.
The utility model has the advantages that:
This utility model novel in structural design, what be can ensure that spool in the mechanical strength of spool and use procedure by rational valve core structure blocks performance, and screwed retaining ring can ensure that liquid will not enter valve rod and spool link, it is ensured that the reliability of connection and fastness.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model screwed retaining ring.
Detailed description of the invention:
Referring to accompanying drawing:
Magnetic anti-theft soft sealing gate valve, including valve body 1, the left and right of valve body 1 is respectively arranged at two ends with the inlet 2 with valve pocket UNICOM and liquid outlet 3, the upper end of valve body 1 is fixed with valve gap 4, also has the valve rod 5 extending in valve pocket from valve gap 4 upper end, it is tightly connected between valve rod 5 outer wall upper end and valve gap 4 inwall, valve gap 4 and valve rod 5 upper end are provided with end cap 6, the lower end of valve rod 5 is provided with spool, spool includes inner bracing piece 7, EPDM rubber set 8 it is set with outside inner bracing piece 7, inner bracing piece 7 upper end screws and is provided with screwed retaining ring 9, screwed retaining ring 9 withstands EPDM rubber and overlaps 8 ends, the neck bush 10 of metal tub it is coated with in EPDM rubber set 8.
Screwed retaining ring 9 outer wall is provided with the external seal groove 9-1 of annular, screwed retaining ring 9-1 outer wall lower end is provided with the exterior seal ring installation step 9-2 of annular, external seal groove 9-1 and exterior seal ring installation step 9-2 constitutes the positioning boss 9-3 of annular, exterior seal ring is provided with and does not come off, screwed retaining ring endoporus is arranged at intervals with multiple tracks inner seal ring mounting groove 9-4, it is ensured that liquid will not enter in valve rod and spool joint gap.
