Abstract
The utility model discloses a stop valve which comprises a valve body, further comprises a ceramic spherical valve element and a valve rod, wherein a valve element placing room is arranged in the valve body, a liquid inlet channel and a liquid outlet channel are arranged on the valve body, a round seal opening is formed at the bottom of the valve element placing room, an output connection opening is formed on the side wall of the valve element placing room, the liquid inlet channel is communicated with the round seal opening, the liquid outlet channel is communicated with the output connection opening, the ceramic spherical valve element is placed in the valve element placing room, the diameter of the round seal opening is less than the diameter of the ceramic spherical valve element, and one end of the valve rod extends to the valve element placing room, is movably connected with the ceramic spherical valve element, and tightly presses the ceramic spherical valve element on the round seal opening. The stop valve is simple in structure, convenient to use, low in abrasion, convenient to maintain and good in sealing performance, and can effectively and rapidly achieve blocking and opening of channels.
Description
Technical field
The utility model relates to the valve field, is specifically related to a kind of stop valve, is applicable to the industries such as electric power, water conservancy, chemical industry.
Background technique
Stop valve mainly is comprised of parts such as valve body, valve rod, spools at present, promotes spool by valve rod in use, so that seal spool is blocked on the passage that need to close, realize closing of stop valve, when unclamping valve rod, spool leaves blocking position, and pent passage is opened.But spool is taper valve core at present, and when realizing stopping up, spool is the face contact with contacting of valve body, so that the serious wear of spool needs more power to remove to compress and push open spool simultaneously, uses inconvenient like this.
The model utility content
The purpose of this utility model is the problems referred to above that are for the prior art existence, and a kind of stop valve is provided, and spool is the ceramic spherical spool, realizes that spool and contacting of valve body are the line contact of random position, and is easy to use and reliable.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of stop valve, comprise valve body, also comprise ceramic spherical spool and valve rod, be provided with the spool holding chamber in the valve body, be provided with feed pathway and liquid outlet channel on the valve body, spool holding chamber bottom offers the circular seal mouth, spool holding chamber sidewall offers the output connecting port, feed pathway is communicated with the circular seal mouth, liquid outlet channel is communicated with the output connecting port, the ceramic spherical spool is placed in the spool holding chamber, and the diameter of circular seal mouth is less than the diameter of ceramic spherical spool, and valve rod one end stretches in the spool holding chamber and is flexibly connected and the ceramic spherical spool can be pressed on the circular seal mouth with the ceramic spherical spool.
Aforesaid valve rod stretches on the end of spool holding chamber and is arranged with sealing drilled packing ring, and sealing drilled packing ring is fixed on the valve body.
The end that aforesaid valve rod and ceramic spherical spool are flexibly connected is provided with the containing groove adaptive with ceramic spherical spool profile, and the ceramic spherical spool is fastened on and contains in the groove.
The utility model compared with prior art has the following advantages:
1, simple in structure, easy to use;
2, wearing and tearing are little, are convenient to safeguard;
3, good seal performance can realize closing and opening of passage effectively efficiently;
4, existing zirconium oxide, aluminium oxide, silicon nitride ceramics spool have highly corrosion resistant, strong alkali-acid resistance, resistant to elevated temperatures performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1-valve body; 2-spool holding chamber; 3-ceramic spherical spool; The 4-valve rod; The 5-feed pathway; The 6-liquid outlet channel; 7-circular seal mouth; The 8-sealing drilled packing ring; 9-exports connecting port.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of stop valve, comprise valve body 1, also comprise ceramic spherical spool 3 and valve rod 4, be provided with spool holding chamber 2 in the valve body 1, be provided with feed pathway 5 and liquid outlet channel 6 on the valve body 1, spool holding chamber 2 bottoms offer circular seal mouth 7, spool holding chamber 2 sidewalls offer output connecting port 9, feed pathway 5 is communicated with circular seal mouth 7, liquid outlet channel 6 is communicated with output connecting port 9, ceramic spherical spool 3 is placed in the spool holding chamber 2, the diameter of circular seal mouth 7 is less than the diameter of ceramic spherical spool 3, and valve rod 4 one ends stretch in the spool holding chamber 2 and are flexibly connected and ceramic spherical spool 3 can be pressed on the circular seal mouth 7 with ceramic spherical spool 3.Valve rod 4 stretches on the end of spool holding chamber 2 and is arranged with sealing drilled packing ring 8, and sealing drilled packing ring 8 is fixed on the valve body 1.Sealing drilled packing ring 8 materials are graphite.Valve rod 4 is provided with the containing groove adaptive with ceramic spherical spool 3 profiles with the end that ceramic spherical spool 3 is flexibly connected, and ceramic spherical spool 3 is fastened on and contains in the groove.
In use, when needs were closed stop valve, valve rod 4 promoted ceramic spherical spool 3 and is blocked on the circular seal mouth 7, and feed pathway 5 disconnects with liquid outlet channel 6 and being communicated with; When the needs opening stop valve, valve rod 4 unclamps, and drives ceramic spherical spool 2 and moves up, simultaneously because the seal action of stuffing box packing 8 so that medium is exported by liquid outlet channel 6, is realized the unlatching of stop valve.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
