Abstract
The utility model discloses a flat gate valve and belongs to the valve manufacturing technical field. The flat gate valve comprises a valve bonnet, a switching joint, an O type sealing ring, an outer hexagonal screw, an outer sleeve of an indicator, a protective sleeve of the indicator, the indicator and a hand wheel, wherein the indicator is arranged at the top of the flat gate valve; the external of the indicator is provided with the outer sleeve of the indicator; the external of the outer sleeve of the indicator is provided with the protective sleeve of the indicator; the outer sleeve of the indicator and the protective sleeve of the indicator are fixed on the valve bonnet through the outer hexagonal screw; the O type sealing ring is arranged between the switching joint and the valve bonnet; and the hand wheel is arranged at the top of the flat gate valve. The flat gate valve has the advantages of being convenient and simple to open and close the flat gate valve for operators due to the fact that a switch press-button is arranged on the outer sleeve of the indicator; greatly extending the service life; and being capable of guaranteeing normal operation of the indicator due to the fact that the external of the indicator is provided with the outer sleeve of the indicator and the protective sleeve of the indicator.
Description
Technical field
The utility model belongs to technical field of valve manufacturing, relates in particular to a kind of plate valve.
Background technique
In the industries such as oil, chemical industry, rock gas, plate valve is low than ball valve because of its compact structure, manufacture cost, open and close the advantages such as moment is little, safe and reliable, is widely used, and plate valve is the abbreviation of Parallel gate valve Parallel slide valve, is a kind of of gate valve.
As shown in Figure 1, the existing product FC type plate valve that uses in the market belongs to dark rod flat plate gate valve, its working procedure is: valve rotates by handwheel (4) and drives the opening and closing that crossover sub (2) rotation realizes valve, yet the opening and closing of valve can only be indicated by the switch bearing mark on handwheel (4) switch of valve, can not clearly indicate the switching position of valve, the operator can only be valve switch on earth, then turn round 1/4 circle, allow valve be in quick condition; When the frequent switch of valve can affect the working life of valve on earth.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of plate valve, has the advantages such as topology layout is reasonable, easy to use, greatly extend the working life of valve.
The utility model is to realize by following technological scheme:
Plate valve; its structure is made of: bonnet, crossover sub, O RunddichtringO, outer-hexagonal bolts, indicator overcoat, indicator protecting jacket, indicator, handwheel; wherein be provided with indicator at valve top part; the outer installment of indicator has the indicator overcoat; the outer installment of indicator overcoat has the indicator protecting jacket; indicator overcoat and indicator protecting jacket are fixed on bonnet by outer-hexagonal bolts, are provided with the O RunddichtringO between crossover sub and bonnet, and handwheel is arranged at the top of valve.
Described indicator overcoat, it is provided with the square groove, indicator puts outward and is provided with the valve switch button, the operator passes through switch button, direct control valve has avoided the operator not understand the stroke of valve or valve opening be closed to the end, and then turns round, and the damage valve, thereby play the working life that extends valve.
Described indicator, it is threaded connection on crossover sub, and external stability is in the square groove of indicator overcoat, and when preventing that crossover sub from rotating, indicator and then rotates together, guarantees the motion that indicator can only upper-lower position.
Described indicator protecting jacket, it plays the effect of protection indicator.
Owing to having adopted above technological scheme, the utility model is than prior art, and the beneficial effect that has is:
1), switch button be arranged at indicator put outward, operator's opening and closing equipment is convenient, simple, and has greatly extended the working life of valve.
2), because the outer installment of indicator has indicator overcoat and indicator protecting jacket, thereby can guarantee the normal operation of indicator.
