Description
Technical field
The utility model belongs to conveying valve field, more particularly to a kind of sealing plug-in board valve for controlling powder switch.
Background technology
The different fields such as mine, metallurgy, building materials and chemical industry are widely present the storage, conveying and processing of powder, powder material
The keying control and the isolation of powder processing equipment of storehouse inlet and outlet use push-pull valve more.Push-pull valve has simple in construction, action
The characteristics of reliable, but conventional push-pull valve does not have plate sealing structure, during plate opening and closing, high fineness powder can be from
Spilt in the gap of plate and valve body, cause loss of material and environmental pollution.
The patent document of Application No. 201120281663.7《Dual-layer airtight gate valve device》And Application No.
201220224034.5 patent document《Pressurizing sealing type push-pull valve》Inflation seal ring is used, this sealing means need
Extra power source, the patent document with application number 201310282707.1《Push-pull valve》Equally, it is close to obtain using inflating
Seal effect.The patent of Patent No. 201521074304.9《A kind of coal dust sealed type pneumatic push-pull valve》It is close using asbestos cord
Envelope, this sealing means can keep sealing in a short time, with the extension of time, after being used for multiple times, the sealing effectiveness of asbestos cord
Gradually it is deteriorated, changes frequently, make troubles or shut down to production.
The content of the invention
The utility model solve technical problem be：A kind of Manual flashboard sealed using powder pressure itself is provided
Valve, service life length, push-pull valve can not act caused by can preventing power outage.
The utility model adopts the technical scheme that：
Push-pull valve includes sealing structure and manual driving system, and sealing structure includes valve body and plate, in entering for valve body
Material mouth is welded with deflection cone, and below deflection cone and plate is fixed on sealing ring, and sealing ring and plate upper surface composition are close
Seal structure.When plate is closed, it is full of in seal groove by powder, the stock column static pressure of powder makes sealing ring produce elasticity change
Shape, with closely sealed with plate upper surface, so as to form self sealss.When plate is opened, deflection cone constraint powder medium, powder is avoided
Sealing ring is washed away, to protect sealing ring from the abrasion of powder.
Further, to ensure sealing effectiveness, sealing ring is preferred with flute profile or semicircle rubber, can also use L-shaped.
Further, sealing ring is made by elastic rubber material.
The utility model obtain technological progress be：
This push-pull valve is simple in construction, and size is small, and occupancy installing space is small, is active in one's movements, sealed reliable, push-pull valve is opened manually
Pass avoids influence of the forced outage to push-pull valve, realizes self sealss using powder pressure, does not consume the energy.

Embodiment
Embodiment 1
Fig. 1 is powder self sealss hand operated gate valve schematic perspective view, and Fig. 2 is hand operated gate valve structure sectional view, push-pull valve
Including sealing structure and manual driving system.
Push-pull valve manual driving system as shown in Figures 2 and 3, mainly there is turn-screw 6, feed screw nut 5, feed screw nut 5
It is fixed on plate 4, and is penetrated among turn-screw 6 using fastener 14, turn-screw 6 is by lead screw shaft bearings 7 and leading screw branch
Support set 8 is fixed, and rotation can be driven by handwheel 9, flat key 13 is equipped between handwheel 9 and turn-screw 6 to transmit moment of torsion.The band of handwheel 9
Dynamic turn-screw 6 rotates along different directions, and feed screw nut 5 drives plate 4 to move back and forth in plate back-up roller wheel 10, plate branch
Support roller 10 is fixed in the framework of valve body 1 by roller shaft 11 and fastener 14, the both sides consistent with the moving direction of plate 4.
Push-pull valve sealing structure is main to include valve body 1 as shown in Fig. 2 partial enlargement is shown in Fig. 4, the plate 4 of switching valve body,
Be welded on the deflection cone 2 of the charging aperture upper end of valve body 1, below deflection cone 2 and plate 4 above sealing ring 3, sealing ring 3 with
The bottom surface of deflection cone 2 and the upper surface of plate 4 composition sealing structure, realize the sealing of powder medium.Sealing ring 3 is by sealing ring pressing plate 12
The inner peripheral wall of valve body 1 is fixed on screw 15, to ensure sealing effectiveness, sealing ring 3 is preferred with flute profile or semicircle rubber.When slotting
Plate 4 is entirely insertable valve body 1, when powder material is ended, is full of in the groove of sealing ring 3 by powder, for powder material, its
Good fluidity, the stock column static pressure of powder in feed bin can be passed to sealing ring 3, work of the rubber seal 3 in stock column static pressure
With lower generation elastic deformation, the bottom surface of its upper lip and deflection cone 2 is closely sealed, lower lip with and the upper surface of plate 4 it is closely sealed, can so as to be formed
The self sealss leaned on, prevent powder to outward leakage.When plate 4 is opened, and powder circulates, deflection cone 2 constrains powder medium, avoids powder
Washing away to sealing ring 3 is expected, so as to protect sealing ring 3 from the abrasion of powder, the service life of raising sealing ring 3.
For high temperature powder（≤250℃）, resistant to elevated temperatures rubber seal can be selected.
On the valve body framework of the position of turn-screw 6, two pieces of sealing plates can be up and down installed and form confined space, passed with protecting
Dynamic leading screw 6 improves its service life from the pollution of dust.
This push-pull valve is simple in construction, and size is small, and occupancy installing space is small, is active in one's movements, sealed reliable.It is highly suitable as
The plate control of the high fluidity powder such as coal dust, slag micropowder.Push-pull valve hand switch avoids forced outage to push-pull valve
Influence, realize self sealss using powder pressure, do not consume the energy.
Embodiment 2
For the present embodiment in addition to the shape of sealing ring 3 and embodiment 1 are otherwise varied, other structures are same as Example 1.
The present embodiment sealing ring 3 is shaped as L-shaped, and in the presence of stock column static pressure elastic deformation occurs for sealing ring 3, with
The upper surface of plate 4 is closely sealed, so as to form self sealss, prevents powder to outward leakage.
Compared with Example 1, the size of rubber seal reduces the present embodiment, and bulk can further reduce, very
Suitable for the operating mode of narrow space.
