Abstract
The utility model relates to a special ball valve for chlorine and pertains to a valve for transfer line in chemical industry. The utility model comprises a ball valve body that is positioned in a valve seat and a valve stem that is connected with the ball valve body; the utility model is characterized in that: the ball valve body and the valve stem are connected fixedly into one integrated structure and a ptfe gasket is arranged between the two sides of the axial via of the ball valve body and the valve seat. Having being improved, the ball valve body and the valve stem are connected into a whole and the appearance of the utility model is covered with an erosion resistant coating, therefore, the demand for the material of the ball valve body is decreased and some cheap materials can be chosen, consequently, the utility model has the advantages of simple operation, accurate opening, closing and location as well as low production cost.
Description
Technical field
The utility model belongs to chemical industry transfer line valve, specifically is the special-purpose ball valve of a kind of chlorine.
Background technique
On the transfer line of chemical industry at different purposes, different valves all is installed, in the production or course of conveying of chlorine, the special-purpose ball valve of chlorine also must be installed, mostly the special-purpose ball valve of prior art is simply to process ball valve body by the mode that adopts unlike material, to guarantee antiseptic effect, and the ball valve body of the materials processing of extraordinary material, difference because of material, price is also inequality, but all existed price higher, caused the deficiency of using the manufacturer production cost to increase, and the split-type structurals that adopt between such special-purpose ball valve body and the valve rod more, after the long-time use of ball valve, be easy to generate looseningly between the two, cause ball valve to close or open to put in place inaccurate, bring some disadvantageous potential safety hazards for the production of enterprise.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and prior art is improved, and provides a kind of easy to implement, closes or open accurate positioning, the special-purpose ball valve of the chlorine of low cost of manufacture.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be the special-purpose ball valve of a kind of chlorine, comprise the ball valve body that is arranged in the valve seat and with the valve rod that ball valve body links, it is characterized in that ball valve body and the valve rod formula structure that is fixedly connected, and between ball valve body axial hole two ends and the valve seat polytetrafluoroethylene sealing gasket be set.
The surface of described ball valve body and valve rod all covers the teflon anti-corrosion layer, or is the vinylidene fluoride layer, or the Teflon layer for spraying.
The utility model is after above-mentioned improvement, because ball valve body and valve rod are connected firmly for an integral body, again because outer surface all is covered with anticorrosive coat, therefore the requirement to the ball valve body material reduces, can select some cheap materials for use, event has easy to implement, closes or open accurate positioning, advantage of low manufacturing cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model embodiment sectional structure schematic representation.
Embodiment
As shown in Figure 1, the special-purpose ball valve of this chlorine, comprise the ball valve body 4 that is arranged in the valve seat 1 and with the valve rod 5 that ball valve body 4 links, it is characterized in that ball valve body 4 and the valve rod 5 formula structure that is fixedly connected, and between ball valve body 4 axial hole two ends and the valve seat 1 polytetrafluoroethylene sealing gasket 2,7 be set.
Described ball valve body 4 all covers teflon anti-corrosion layer 6 with the surface of valve rod 5, or is the vinylidene fluoride layer, or the Teflon layer for spraying.
The utility model is after above-mentioned improvement, because ball valve body 4 and valve rod 6 are connected firmly for an integral body, again because outer surface all is covered with anticorrosive coat, therefore the requirement to the ball valve body material reduces, can select some cheap materials for use, event has easy to implement, closes or open accurate positioning, advantage of low manufacturing cost.
Claims (2)
1, the special-purpose ball valve of a kind of chlorine, comprise the ball valve body that is arranged in the valve seat and with the valve rod that ball valve body links, it is characterized in that ball valve body and the valve rod formula structure that is fixedly connected, and between ball valve body axial hole two ends and the valve seat polytetrafluoroethylene sealing gasket be set.
2, the special-purpose ball valve of chlorine according to claim 1 is characterized in that the surface of ball valve body and valve rod all covers the teflon anti-corrosion layer.
